Technical field

TECHNICAL FIELD [0001] The present invention relates to a control method for embedded devices, and more particularly to an image display device, an image data providing device, an image display system, an image display system control method, and a control for controlling an image display device that displays an image. The present invention relates to a program and a recording medium.

Background art

In recent years, the use of digital home appliances has become widespread. And, as represented by digital TVs and HDD recorders, these digital home appliances with communication functions are connected to the network and can use various services and execute various functions via the network. It ’s been like that.

[0003] However, on the other hand, these digital home appliances are required to be packed with many functions. As a result, the challenges of development sites trying to meet the diversity of digital home appliances are becoming increasingly serious. Specific issues include reducing development and test man-hours, reducing losses due to rework, and responding quickly to changes in device functions in order to respond to rapidly changing markets. It is done.

[0004] Under such circumstances, there is a need for a mechanism that can efficiently develop digital home appliances. In addition, it is desirable that a digital home appliance once on the market can provide a mechanism that allows a user who purchased the device to easily update the device program.

[0005] As a method of changing the function of a digital home appliance, for example, a program such as Java (registered trademark) in a mobile phone is downloaded, or a digital home appliance (eg, HDD recorder) is automatically updated. (For example, see Non-Patent Document 1 and Non-Patent Document 2 below).

However, there is a problem that it is not easy to change the function of the device by changing the program of the digital home appliance.

Specifically, in the methods described in Non-Patent Document 1 and Non-Patent Document 2, digital Internet browsers provided in home appliances are software for browsing data acquired from external devices. Digital home appliances can acquire and display data distributed via the Internet using the Internet browser function. At this time, if the data to be distributed is changed, the display content of the digital home appliance can be changed.

[0008] However, it is not easy to change the function executed by the digital home appliance with respect to the display content. This is because the function of the Internet browser is determined by a program stored in the storage device by the digital home appliance. In order to change the Internet browser function of the digital home appliance, the data distributor needs to update the program and distribute the updated program to the digital home appliance.

[0009] For the distributor, there is a problem that the program must be updated one after another in order to change the function, which increases the development burden. In addition, users of digital home appliances are forced to acquire new programs from the distribution source each time functions are updated, and there is a problem that convenience is impaired.

[0010] Moreover, the mechanism for changing the functions of digital home appliances as described above is not well-equipped compared to the mechanism for changing the functions of personal computers (PCs). This is because many digital home appliances such as televisions and mobile phones are embedded devices, and the functions executed by the embedded devices cannot be rewritten into a nonvolatile storage device such as a ROM (read only memory) during manufacturing. This is because it is realized by a program that can be burned.

[0011] Therefore, even if you try to change the function of digital home appliances that have been put on the market once, R

There is no choice but to replace the OM itself. However, such a method is not an easy task that anyone can do, and it is not realistic because of the enormous cost.

[0012] It should be noted that the above-mentioned problem does not occur only in digital home appliances, as long as it is an embedded device that performs a function by a program burned into ROM at the time of manufacture, such as the digital home appliance. It will occur.

In the present embodiment, as an example, a case will be described in which the image data providing device (display data generating device 2) and the image display device (television 1) of the present invention are applied to a network album system as shown in FIG.

[0039] The network album system is a communication terminal device (computer (PC) 4) such as a PC or a mobile phone. The album (photo or photo) is transferred to the album management server (album management server 3) via a communication network such as the Internet. A system for displaying photos in which an image display device having a communication function acquires and displays the photos (images) of the album stored in the album management server on its own device. It is. More specifically, the image data providing apparatus generates display data for displaying the photograph on the image display apparatus, and supplies the display data to the image display apparatus. The photo can be displayed as intended.

In the present embodiment, the image display device according to the present invention will be described as a television 1 having a communication function connected to the Internet. The image data providing apparatus according to the present invention will be described as a display data generating apparatus 2 that generates display data necessary for the television to display various information such as photographs on its screen. [0041] [Display data]

The display data is information necessary for generating the display screen of the television 1. FIG. 3 is a diagram schematically showing the data structure of the display data. As shown in FIG. 3, the display data 7 according to the present embodiment is such that the television 1 displays a specific display screen or performs various application functions (hereinafter referred to as a photo application function) of the network album. 1 includes a control script 110 in which control commands for 1 are described, and a display object 111 such as a still image such as a photograph, a menu screen, and an operation button image to be displayed on the television 1. In the example shown in FIG. 3, the display object 111 included in the display data 7 is not limited to force S, which is a JPE G format photograph (still image). Any data format can be included in the display data 7 as the display object 111 as long as it can be handled by the television 1 for display on its own device. For example, moving image data or text data may be used as the display object 111. The text data may be included in the display data 7 as an object (* * .txt) different from the control script 110, or the SVG data (**. Svg) for realizing the control script 110 may be included. It may be the one defined in! /.

[0042] In addition, the display data 7 is not limited to an object (display object 111) that is a display process target such as an image, a video, or a text, and is reproduced by the television 1 like audio data. In addition, any type of object (reproduction target) that can be presented to the user may be included. The control script 110 is not limited to the display object 111. The control script 110 includes a description for identifying the object and a description for the object so that the TV 1 can reproduce and present to the user all types of objects included in the display data 7. Various actions of TV 1 can be defined.

In the present embodiment, the control script 110 can be roughly classified into two types. The first is how to display the display object 111 (that is, an image object such as a photograph, or a GUI screen, text data, etc. as a display object defined only on SVG that implements the control script 110). This is a layout definition script 112 that defines whether to display. With this layout definition script 112, the television 1 can determine what data contained in the display data 7 should be displayed and how.

[0044] As an example of the layout definition script 112, a display for uniquely identifying the display object 111 Operation items that can be executed by the TV 1 when the display object specifying script 121 indicating the correspondence between the object identification information and the display position 'display size information or the display data 7 is displayed. Specifies the operation menu identification script 122 that defines the operation menu screen indicating the display method and various information associated with each display data (album title, photo title, comments attached to them, etc.) Attribute information specific stub 123, etc., can be considered.

[0045] Second, in response to an event that has occurred on the television (for example, the passage of a prescribed time, the start / end of a prescribed operation, reception of display data, or key input by the user) This is an operation content definition script 113 that defines the content of the behavior of. With this operation content definition script 113, the television 1 can determine when, what, what and how it should be executed.

[0046] Examples of the operation content definition script 113 include a state transition definition script 131 that defines which display data is to be displayed (requested and acquired) next when an event occurs, As the photo application function, the operation function definition script that defines the predetermined processing (image rotation, color change, text data change, printing, etc.) that the TV 1 should perform on the displayed display data 132 Etc. are considered.

[0047] In more detail, the above-described control script is one of the various types of basic functions (hereinafter referred to as basic functions) pre-installed in the television 1, which is the basis for realizing the photo application function. It defines how to use it. According to this control script, the TV 1 selects each basic function built into its own device as appropriate and combines it to combine one function (Photo application function (first function / second function)). The power to execute is S.

[0048] A basic function is a low-level function called by a control script for realizing a photo application function, and realizes one specific simple function. The control script describes when and which basic function to call. The TV 1 can implement the photo application function by calling and executing several basic functions as appropriate according to the control script. It becomes.

In this embodiment, the control script has a description for calling a basic function. Only the actual execution code, ie, the basic function program,

It is burned into a ROM etc. at the time of manufacture of 1 (Basic function program storage unit 29 in Fig. 1). Therefore, the basic function program of TV 1 cannot be easily rewritten after it goes on the market.

[0050] However, as described above, the basic function is a low-level function called by the control script described above. By combining these various basic functions, various photo application functions can be realized. Therefore, the photo application function executed by the television 1 can be changed only by changing the procedure for calling the basic function, that is, the combination of the basic functions, without changing the basic function itself. The combination of the basic functions can be easily changed using a control script.

[0051] The control script can be configured as text data described in, for example, XML (extensible Markup Language), and can easily be changed in content and provided to the television 1. The layout definition script 112 can be described as, for example, SVG (Scalable Vector Graphics).

It is a configuration. Therefore, when each of the above sections does not limit the configuration of the image display apparatus of the present invention, and the image display apparatus is not realized as the television 1, the image display apparatus may not include the above sections.

[0093] The above-described display control unit 24 further divides the display area of the display unit 15 into a plurality of areas, controls each of the plurality of display areas (draws separately), and displays another display screen. It may have a function. For example, the display control unit 24 divides the display area of the display unit 15 into two, displays the video data included in the broadcast data in the first display area, and displays the album photos in the second display area. You can also control the display (two-screen display). In addition, the display area is divided into three, and the third display area is displayed on the electronic program guide and the Internet. It is also possible to display web pages that are publicly available on! (3-screen display).

[0094] As described above, even when the two-screen / three-screen display is executed on the television 1, the display data generating device 2 can display the normal display area during full screen display. Assuming that, display data for displaying various display screens will be provided to TV 1. In such a case, the television 1 needs to display the received display data on a full screen.

[0095] Therefore, when the display control unit 24 receives the display data from the display data generating device 2, the display control unit 24 has received the display data even when controlling the 2-screen / 3-screen display. Accordingly, the control of the display unit 15 is switched to the control of the full screen display. Then, the display control unit 24 controls the display unit 15 to display the display data on a full screen according to the analysis result of the display data execution processing unit 40. As a result, even if the display control unit 24 controls the display of a plurality of areas until immediately before, the display data provided from the display data generating device 2 can always be displayed on the full screen. As a result, it is always possible to display a photograph at a predetermined display size intended by the display data generating device 2.

The event processing unit 11 detects various events that occur in the television 1 and transmits a predetermined instruction signal to the display data request processing unit 30 or the display data execution processing unit 40. The event processing unit 11 detects the various events based on signals notified from the input / output control unit 20 (for example, the operation receiving unit 21 and the display data reception control unit 23) and a timer unit (not shown). Then, the processing execution timing in the display data request processing unit 30 or the display data execution processing unit 40 is controlled.

[0097] More specifically, the event processing unit 11 determines the display data request processing unit 30 or from the content of the notified signal and the current state of the television 1 based on a predetermined rule. The display data execution processing unit 40 determines a process to be executed. Then, an instruction is sent to the display data request processing unit 30 or the display data execution processing unit 40 to execute the determined process.

The timer unit (not shown) passes a timer notification to the event processing unit 11 when, for example, a predetermined time has elapsed since being activated. When the operation reception unit 21 receives an instruction signal input by the user via the operation unit 13, the operation reception unit 21 notifies the event processing unit 11 of the instruction signal. The display data reception control unit 23 is displayed via the reception unit 14b. When the display data is received from the display data generating device 2, the event processing unit 11 is notified that the display data has been received.

[0099] As described above, as an example of various events detected by the event processing unit 11, when a predetermined time has elapsed since a certain predetermined operation has occurred, a predetermined time of the operation unit 13 is displayed during display of a certain display screen. Or when the display data transmitted from the display data generating device 2 is received.

The display data request processing unit 30 generates a display data request message 6. More specifically, in response to an instruction from the event processing unit 11 (for example, when the user inputs an album display instruction signal), the display data request message 6 for requesting a display screen for displaying the specified album is generated. To do. Details of the display data request processing unit 30 and the display data request message 6 will be described later.

[0101] The display data execution processing unit 40 analyzes the display data, and processes the display data based on the analysis result. The display data execution processing unit 40 includes a control script execution unit 41 that executes the photo application function according to the control script, and a basic function execution unit 42 that executes the basic function program stored in the basic function program storage unit 29. It is equipped with. The control script execution unit 41 analyzes the control script included in the display data in accordance with an instruction from the event processing unit 11 (for example, when receiving display data), and performs basic operations according to the contents of the analyzed control script. The function execution unit 42 is controlled to execute one or a plurality of basic functions and execute a single photo application function.

Specifically, in response to the notification from the event processing unit 11, the control script execution unit 41 starts control script execution processing. That is, the control script is read and the control script is processed from the first line. For example, it manages the control structure such as the If statement included in the control script. Further, the control script execution unit 41 manages calculation variables and key input values (notified from the event processing unit 11).

[0103] Here, when a description for calling a basic function is included in the control script, the control script execution unit 41 passes an argument to the basic function execution unit 42 based on the processing so far. The basic function execution unit 42 executes the basic function specified by the control script execution unit 41 and returns the result to the control script execution unit 41. The control script execution unit 41 receives the result from the basic function execution unit 42 and continues the control script execution process described above. In accordance with the control script, the control script execution unit 41 terminates the control script execution process, for example, by displaying an image obtained based on the basic function.

[0105] As a photo application function that the control script execution unit 41 controls and executes the basic function execution unit 42, for example, according to the layout definition script of the control script, a plurality of album photos can be displayed as a thumbnail list. It is assumed that the displayed photo is rotated 90 degrees and the operation menu (G UI screen) showing a list of operation items that can be operated on the displayed photo is displayed. .

Based on the drawings, specific examples of the basic function executed by the basic function executing unit 42 and the photo application function executed by the control script executing unit 41 are as follows.

For example, the script “rotate (90, 960, 540)” in the broken line frame 251 in FIG. 25 is a basic function for executing rotation of a predetermined frequency image based on an argument passed from the control script execution unit 41. The basic function execution unit 42 executes the basic rotation function.

[0108] The script “rgb (0, 0, 0)” in the broken line 252 in FIG. 26 calls the basic function for setting the background color of the text object based on the argument passed from the control script execution unit 41. The basic function execution unit 42 executes the basic function for setting the background color.

[0109] The script “font_size = 28” in the dashed frame 253 in FIG. 13 is for calling the basic function for setting the font size of the text object. The script “fill = # 000000j” in the dashed frame 254 is This is for calling up the basic functions for setting the color of the text object.The basic functions are executed by the basic function execution unit 42.

[0110] Alternatively, the script “setTrait (“ visibility ”, 'hidden')” in the broken line frame 261 in FIG. 12 is a function for setting the characteristic value “visibility” of the structure to “hidden”. The execution unit 41 executes it.

[0111] The script 132b in Fig. 12 is executed by the control script execution unit 41, and opens / closes the sub operation menu (sub operation menu 1106 in Fig. 11 (c)) and selects the sub operation menu. When calling a function (basic function / photo application function) corresponding to the marked item! /, The photo app function is defined. According to the script 132b, when the control script execution unit 41 detects that a predetermined button is pressed when the sub operation menu is closed, the sub operation menu corresponding to the selected item of the main operation menu (here Then, the function to display “sub menu2”) is executed. On the other hand, when the sub-operation menu is open and a pressing of a predetermined button is detected, the control script execution unit 41 calls the menuFunction function (photo application function) corresponding to the selected item of the open sub-operation menu. Run out and run. A specific example of the menuFunction function is shown in script 132d in FIG. Script 132d defines candidate functions that may be selected during the display of “submenu2” described above.

[0112] The script “setFloatTrait (" r ", '100')" in the broken line frame 262 in Fig. 32 sets the numerical data 100 to the r value of the structure (the value of the circle object in the script 112a). This is a function executed by the control script execution unit 41.

[0113] However, the photo application function is not limited to the above example. Details of the configuration of the display data execution processing unit 40 and details of the photo application function executed by the display data execution processing unit 40 using basic functions will be described later.

[0114] According to the above configuration, the control script execution unit 41 of the display data execution processing unit 40 receives the display data stored in the display data storage unit 51 in response to an instruction from the event processing unit 11. The control script is analyzed, and the basic function is called according to the analysis result. In other words, the basic function executed by the basic function execution unit 42 is appropriately combined to execute one photo-copy function.

[0115] Thus, various photo application functions can be realized on the television 1 without changing the basic function program using the control script. As described above, the control script is generated externally and provided to the television 1. Therefore, even after TV 1 enters the market, it is possible to flexibly change the photo application function executed by TV 1, and update the program stored in basic function program storage unit 29! / It is possible to easily change the functions of TV 1.

[0116] In addition, since functions can be easily changed in this way, a huge amount of functions to be incorporated in advance are assumed to cover all needs before shipping. It is possible to eliminate the waste of having the function in advance. As a result, it is possible to reduce the burden related to the development of TV 1.

[0117] Further, the control script is provided to the television 1 in the display data. Therefore, a control script is provided in association with the display data (display screen), and the display data is also generated on the display data generation device 2 (display data generation device 2). Management is also facilitated on the side that receives and processes (TV 1). By providing a control script for each display data, only the functions that the television 1 needs to execute when displaying the display data can be efficiently provided according to the display data. It becomes Kanakura.

[0118] From the above, it is possible to perform efficient development, and it is possible to easily change the function of a device on the market without updating the program.

[Outline of configuration of display data generation device]

FIG. 4 is a block diagram showing a schematic configuration of the display data generating apparatus 2 according to the embodiment of the present invention. As shown in FIG. 4, the display data generating device 2 includes a communication unit 63, a control unit 60 that performs overall control of the display data generating device 2, and a storage unit 90.

[0120] The control unit 60 controls various operations of each unit included in the display data generation device 2, and includes a request message analysis unit 70, a control script generation unit 80, a pattern data selection unit 61, and display data. A generation unit 62 is included. The control unit 60 reads out various programs recorded in the storage unit 90, controls each unit of the display data generating device 2 of the present invention, and generates display data (and a control script included therein). Perform various processes.

[0121] The storage unit 90 records the control program, the OS program executed by the control unit 60, and various data read when the control unit 60 executes various processes for generating display data. It consists of a non-volatile storage device such as a hard disk. The various data are stored in various storage units inside the storage unit 90, that is, the pattern data storage unit 91, the display object storage unit 92, and the like. However, the various data stored in the storage unit 90 is not limited to the above.

[0122] The communication unit 63 is a display data generation device in the network album system 100. 2 Communicates with external devices via a communication network, and includes a receiving unit 63a and a transmitting unit 63b.

[0123] Specifically, the receiving unit 63a receives the display data request message 6 transmitted from the television 1, and the display data request message 6 received via the receiving unit 63a is Is transmitted to the request message analysis unit 70 of the control unit 60. The transmitter 63b transmits the display data 7 generated in response to the request from the television 1. The transmission unit 63b transmits the display data 7 transmitted from the display data generation unit 62 to the television 1 that has requested it.

[0124] Further, when generating the display data 7, if the communication unit 63 is the display data 7 for display screen for displaying the album photos, the album management server 3 (Fig. 2) Communicates with the album management server 3 and requests the album 5 server (photo) to be displayed from the album management server 3 to obtain the album 5 (photo) from the album management server 3.

[0125] Note that when the display data generating apparatus 2 has the network album DB8, it is not necessary to acquire the album 5 (photo) using the communication unit 63. In this case, the album 5 (photo) received by the receiving unit 63a from the communication terminal device such as PC4 is stored in the network album DB8.

[0126] The request message analysis unit 70 displays the display data request message transmitted from the television 1.

6 is analyzed. For example, when the display data request message 6 is a message requesting slide show display screen display data for a certain album, the request message analysis unit 70 includes the album included in the display data request message 6. ID, display screen ID (information that can determine that a slide show display screen is requested), terminal ID (information that can identify the requesting TV 1), and other related information are extracted.

The pattern data selection unit 61 selects the optimum pattern data for generating the requested display data according to the analysis result of the request message analysis unit 70. The pattern data selection unit 61 selects the optimum pattern data specified by the analysis result from the pattern data storage unit 91. The pattern data selected by the pattern data selection unit 61 is transmitted to a control script generation unit 80 that generates a control script from the pattern data. The pattern data is pattern information (or a combination of fixed scripts) of the control script having the fixed types of various scripts described above. That is, a control script template. Information that shows the correspondence between the display object identification information and its display position's display size information, information that specifically defines the screen of the operation menu, album titles, comments, etc. are called the contents of the control script. If so, it can be said that the pattern data is a container before the contents are embedded.

[0129] For example, when the analysis of the request message analysis unit 70 specifies that the slide show display screen display data is requested from the television 1, the pattern data selection unit 61 receives the slide show from the pattern data storage unit 91. Select the control stub pattern data to configure the display screen. Next, the control script generation unit 80 generates a control script based on the selected pattern data.

[0130] The control script generation unit 80 uses the pattern data selected by the pattern data selection unit 61 to generate a control script to be included in the requested display data.

[0131] Based on the analysis result of the request message analysis unit 70, the control script generation unit 80 extracts all the information to be included in the display data from various information stored in the storage unit 90 (control). Identify the script contents). Then, the specified contents (for example, album title, photo ID, screen transition destination information, etc.) are embedded in the pattern data to complete the control script.

In the above example, the completed control script is a control script for configuring the slide show display screen.

The display data generation unit 62 generates display data designated by the display data request message 6 and transmits it to the television 1. More specifically, the control script generated by the control script generation unit 80 and the display target specified by the display target specifying script included in the control script are combined to display the display requested by the television 1. Display data for displaying the screen is generated.

[0134] The display data generated in this way includes a control script that is optimal information according to the request of the television 1, that is, the content of the display data request message 6.

[0135] According to the above configuration, according to the analysis result of the request message analysis unit 70, the pattern data The optimal pattern data is selected by the data selection unit 61, and the optimal content is specified by the control script generation unit 80. Therefore, the display data generating device 2 can complete an appropriate control script according to the display data requested from the television 1 and provide it to the television 1. The TV 1 can realize the photo application function according to the appropriate control script.

[0136] Based on the above, a control script is used to perform an operation suitable for the display data according to the content of the display screen (display data) requested and displayed by the TV 1. TV 1 can be controlled.

In this way, by generating and providing a control script to the television 1, it becomes possible to easily change the function of the television 1 without updating the program. Further, since the control script is generated in association with the display data, the control script customized according to the content of the display data can be provided to the television 1.

[Network Album System Processing]

FIG. 5 is a sequence diagram showing a processing flow of each device in the network album system 100 according to the embodiment of the present invention.

[0139] When the event processing unit 11 of the television 1 detects a predetermined event (e.g., the elapse of a predetermined time or reception of an instruction signal from the user operation unit 13) (YES in S1), the display data request processing The unit 30 executes display data request processing for requesting display data from the display data generating device 2 (S2). Specifically, a display data request message 6 is generated and transmitted to the display data generation device 2. The display data request processing unit 30 extracts the related information necessary for the display data generation device 2 to generate display data from the display data request message 6 by the related information storage unit 52 (FIG. 1). May be included.

[0140] When display data generation device 2 receives display data request message 6 from television 1 (YES in S3), request message analysis unit 70 analyzes received display data request message 6 The request message analysis process is executed (S4).

[0141] Subsequently, the pattern data selection unit 61 selects optimal pattern data for generating display data to be provided to the television 1 according to the analysis result of S4 (S5). The pattern data is stored in the pattern data storage unit 91 (Fig. 4). The data selection unit 61 selects the optimum pattern data from here.

[0142] Next, the control script generation unit 80 displays the display object to be displayed on the television 1 or causes the television 1 to perform a specific operation based on the selected pattern data. The process for generating the control script (control script generation process) is executed (S6). Subsequently, display data including the control script generated by the control script generation unit 80 and the display target to be displayed stored in the display target storage unit 92 (FIG. 3) is generated (S7).

[0143] Finally, the display data generating device 2 transmits the display data generated in S7 to the requesting television 1 (S8).

[0144] The television 1 receives the display data 7 from the display data generation device 2 (S9). When the event processing unit 11 of the television 1 detects a predetermined event (reception of the requested display data or reception of an instruction signal from the user operation unit 13) (YES in S10), the display data execution processing is performed. Unit 40 executes processing of the received display data (display data execution processing) (Sl l) ₀

[0145] The contents of the processing executed by the display data execution processing unit 40 are described in the control script included in the received display data. The control script execution unit 41 follows the control script according to the basic function execution unit. By controlling 42, it is possible to execute various processes (photo application functions) as network album application functions using basic functions.

[0146] For example, if the display data includes a photo as a display object and a control script including a layout definition script that defines the layout for displaying the photo, the display data The execution processing unit 40 displays the photo according to the layout definition script of the control script.

[0147] As described above, the television 1 can execute the photo application function by following the control script included in the display data.

[0148] Therefore, by changing the description of the control script, the function of the television 1 can be easily changed.

[0149] Further, the display data generation device 2 is adapted to the optimal display data ( Control script) and control the operation of the TV 1.

In the following description, the following three examples will be given as examples of the photo application function executed on the television 1. In the following embodiments, a procedure for changing each photo application function of the television 1 using a display data control script and a basic function of the television 1 will be described in detail.

[0151] (Function 1: Display operation menu / execute operation · · · Embodiment 1)

When the display data about the network album application is displayed on the display unit 15 of the TV 1, the TV 1 presents a list of operation items that can be executed by the TV 1 as an operation menu to the user. In addition, the television 1 receives an operation item selected by the user from the displayed operation menu via the operation unit 13 and the operation reception unit 21, and executes the operation.

[0152] If the control script included in the display data is used, the items of the operation menu to be displayed can be changed for each display data, and the items and contents of operations executed by the television 1 can be flexibly changed. Can be changed.

[0153] Furthermore, if the control script is used, display control of the operation menu on the television 1 can be performed. For example, it is possible to flexibly change the operation menu display position, display timing, and design.

[0154] (Function 2: Specify redrawing area ··· Embodiment 2)

The television 1 generates display screen data based on the display data and draws it on the display unit 15 to display the display screen. When switching the display screen to be displayed, TV 1 redraws the data of the new display screen based on the other display data. At this time, when the area where the display content needs to be changed is not a whole area of the display unit 15 but a part thereof, the television 1 efficiently restricts the redrawing area to the part and efficiently displays the display screen. It can be switched.

[0155] By using the control script included in the display data, it is possible to specify a redrawing area for each display data, and flexibly redraw the TV 1 according to the display contents of the display data. An area can be specified. Furthermore, in general, redrawing complex shapes is a heavy-duty process (clipping) that calculates the area to be redrawn as complex shapes. Processing) occurs. In this regard, TV 1 specifies a redrawing area having a simple shape (for example, a rectangular shape) that includes the entire area of a complex graphic, thereby identifying a redrawing area that is not subject to high-load clipping processing, The redrawing process can be performed efficiently.

[0156] Note that the term "draw" (and other grammatical variations) used here (especially in Embodiment 2) broadly means that data is displayed on a display device (such as the display unit 15). It means the operation of a computer (such as TV 1) to display. Therefore, “Draw” writes (= writing) the data to be displayed on the display device, and converts the data to a format that can be displayed on the display device (= _CO n _V erting), rendering, rasterizing, etc. ¾-!

[0157] (Function 3: Remote control button function assignment '··· Embodiment 3)

The television 1 performs various operations in response to instruction signals input to the operation receiving unit 21 when each button provided on the operation unit 13 is pressed by the user.

[0158] Each of the above buttons has a function assigned in advance, and when the predetermined button is pressed, the television 1 executes a corresponding predetermined operation.

[0159] If the control script included in the display data is used, the functions of the buttons assigned to the operation unit 13 can be changed for each display data.

[0160] Specifically, when a certain button is pressed while a certain display data is displayed, the function to be executed by the television 1 is changed to another function, or a certain operation is performed. The button to be pressed at this time can be changed to another button.

[0161] In the following description of each embodiment, the same reference numerals are assigned to the same members. Therefore, the configuration of each device already described is denoted by the same reference numeral, and redundant description is omitted as appropriate.

[0162] <Embodiment 1>

[Background technology and issues]

Conventionally, devices with built-in computers such as TVs and mobile phones had to change the programs of the built-in applications when changing the appearance of the installed applications or changing the specifications. .

[0163] For example, when the GUI screen is realized by a Web browser, Changes can be realized by rewriting the original data (display data).

[0164] In Patent Document 1 [Japanese Published Patent Publication: JP 2005-51563 (published February 24, 2005)], the distribution side grasps the layout of the image displayed on the receiving side screen, A content distribution method and a content distribution system that change the layout with a simple operation are disclosed.

[0165] However, to change the function of the browser itself, it is still necessary to change the program already installed in the device. Moreover, the function of the content receiving side (embedded device (TV 1)) cannot be flexibly changed according to the content of the content to be distributed (display data).

[0166] In the method of Patent Document 1 described above, if the distribution source creates a program in advance so that the configuration file and plug-in can be distributed and modified later, the function of the distribution destination device is changed. This eliminates the need to rewrite the entire software. However, even in this case, in order to flexibly change the function of the device according to the content to be distributed, it is necessary to distribute the operation menu setting file corresponding to the above content in association with the content. For this reason, there is a problem that management of contents and setting files becomes complicated for both the distribution source and the distribution destination device.

[0167] Therefore, in the present embodiment, a control script that is easy to manage because it is included in the display data is used according to the content of the display data (display screen / content) displayed on the television 1. The TV 1 and the display data generation device 2 (network album system 100) that can select the operation items of the operation menu to be displayed and customize the functions that can be executed by the TV 1 will be described.

[0168] [Details of TV configuration 1]

6 and 9 are block diagrams showing the main configuration of the television 1 according to the present embodiment. FIG. 6 is a diagram showing the display data request processing unit 30 of the television 1 shown in FIG. 1 in more detail.

[0170] Each part of the display data request processing unit 30 is shown in FIG. 5 in response to the event processing unit 11 detecting a predetermined event and notifying the display data request processing unit 30 of a predetermined signal. The display data request message 6 is generated by executing the display data request process (S2).

FIG. 7 is a diagram schematically showing the data structure of the display data request message 6 generated by the display data request processing unit 30. As shown in FIG. FIG. 7 shows a display data request message 6 when a slide show display screen (display data) is requested as an example.

[0172] In the example shown in Fig. 7, the display data request message 6 is configured as a structure in which five records are grouped. In the display data request message 6 shown in FIG. 7, the first column C101 indicates the data name, and the second column C102 indicates the contents of the data with the data name. The data type of each data can be selected as appropriate according to the contents, capacity, and usage of each data.

[0173] When the display data request message 6 requests the slide show display screen, the record R1 indicates the album ID (identification information) of the album to which the photo (request image) to be displayed on the display screen belongs. ing. Record R2 indicates a photograph I D (identification information) of the photograph to be displayed on the display screen. In this embodiment, the photo ID is a display order uniquely defined in the album, and “NO. 1” in FIG. 7 is the display order 1 in the album specified by the record R1. A photograph is shown.

[0174] Record R3 indicates a display screen ID for identifying the type of display screen requested by the display data request message 6 concerned. In the example shown in FIG. 7, the display screen ID “Scr_C” means a slide show display screen. Therefore, the display data request message 6 requests a slide show display screen for slidingly displaying the photos in the display order 1 of the album shown in the record R1! /.

[0175] The record R4 indicates a terminal ID for identifying the television 1 that is the request source that generated the display data request message 6. In the example shown in FIG. 7, the IP address of TV 1 is stored. As a result, the display data generation device 2 displays the display data request message. Therefore, it is possible to specify the power from which the page 6 is transmitted, and therefore, it is possible to specify a reply destination to which the generated display data 7 is returned. The terminal ID may be anything as long as the display data generating apparatus 2 can uniquely identify each terminal (TV 1) that receives the display data 7 in the network album system 100. The display data generation device 2 may be a terminal ID that is assigned individually each time the television 1 is registered, or a MAC address or a product serial number may be used as the terminal ID.

[0176] Further, the display data request message 6 may include the specification information of the television 1 as shown in the records R5 to R7. For example, the display data request message 6 includes specification information of the television 1 (specification information related to the display function such as screen size and resolution, or specification information related to the function of the network album such as model name and software version information). As a result, the display data generating device 2 can generate the display data 7 in accordance with the specification of the requesting television 1.

[0177] The display target ID determining unit 31 in FIG. 6 determines a display target to be requested to the display data generating device 2, and specifies the display target ID. Specifically, the album ID and photo ID to be stored in the records R1 and R2 of the display data request message 6 shown in FIG. 7 are specified.

[0178] For example, the display target ID determination unit 31 specifies the album and photo ID as follows.

[0179] The album ID storage unit 53 stores the album IDs of the albums that the user has viewed in the past. Based on the history information stored in the album ID storage unit 53, the albums viewed in the past are stored. Is displayed on the display unit 15 via the display control unit 24.

[0180] When the user presses the button using the operation unit 13, one of the ano- lems displayed on the display unit 15 is selected, and an instruction signal for instructing the start of the slide show is input. The signal is notified to the display target ID determination unit 31 via the event processing unit 11, and the display target ID determination unit 31 specifies the album ID selected by the user from the album ID storage unit 53. Alternatively, in the state where the album ID input screen is displayed on the display unit 15, the album ID is manually input by the user, and the signal of the pressed button is transmitted to the display target ID determination unit 31, which is displayed in the album. It may be specified as an ID. [0181] As a method for specifying a photo ID, for example, a case where a slide show is predetermined to be displayed in the display order is considered. When the event processing unit 11 detects that the instruction input for instructing the start of the slide show has been performed, the display target ID determining unit 31 specifies NO. 1 representing the first display order as the photo ID. In addition, when the event processing unit 11 detects that the button for selecting the next page is pressed while the first slide show display screen is displayed, the display order, NO. N + You can specify 1 as the photo ID.

[0182] The request display screen determination unit 32 determines the type of display screen to be requested by the display data request message 6 among the various display screens described above. The request display screen determination unit 32 determines which display screen is requested according to the event detected by the event processing unit 11 and the operating state of the television 1 at that time.

[0183] The request rule storage unit 54 stores (1) the display screen ID of the display screen to be requested for the combination of (1) the event detected by the event processing unit 11 and (2) the operating state of the television 1. The request display screen determination unit 32 specifies how the display screen should be requested based on the notification from the event processing unit 11 and the request rule storage unit 54. Is possible. For example, when the event processing unit 11 detects that the display data execution processing unit 40 of the television 1 has activated the photo application function, the request display screen determination unit 32 should request the initial screen of the application. Determine as the display screen.

[0184] The display screen ID of the display screen determined by the request display screen determination unit 32 is included, for example, in the record R3 of the display data request message 6 shown in FIG.

The related information extraction unit 33 acquires, from the related information storage unit 52, related information that needs to be included in the display data request message 6 among various types of related information registered in advance with respect to the television 1.

FIG. 8 is a diagram showing an example of the related information table stored in the related information storage unit 52. As shown in FIG. In the present embodiment, the related information stored in the related information storage unit 52 can be classified into three types.

[0187] In the first column group C11, specification information related to the specification of TV 1, such as “model name”, “terminal ID”, “screen size”, and “number of pixels” of TV 1, is stored. ing. In addition, the net “Software version information” indicating the version of the application software of the work album system may be stored as the specification information. The second column group C 12 contains setting information related to album and photo display such as “(slide) frame advance interval”, “repeat playback”, “comment display”, and “operation method display”. It is remembered. Further, “history display number” for setting the number of album information items displayed on the album history screen may be stored as setting information. As shown in the example in Fig. 8, assuming that "History display count" is set to 2, when the album history screen is displayed, two album history information will always be displayed. Yes. The third column group C13 stores user information related to the user of the television 1, such as “viewer age”, “viewer residence”, and “zip code”.

[0188] In the present embodiment, display data 7 is generated on a display screen (such as a slide show display screen or a thumbnail display screen) related to the display of photos according to the number of pixels of the display unit 15 of the television 1. When requesting such a display screen, the related information extraction unit 33 extracts the “pixel number” information of the television 1 from the related information storage unit 52. The extracted “pixel count” information constitutes the record R5 of the display data request message 6 shown in FIG.

[0189] The message generation unit 34 determines (extracts) according to the notification of the display target ID determination unit 31, the request display screen determination unit 32, and each component S of the related information extraction unit 33 and the event processing unit 11. A display data request message 6 including various information for requesting display data is generated. The display data request message 6 (FIG. 7) generated by the message generation unit 34 is transmitted from the transmission unit 14a to the display data generation device 2 via the message transmission control unit 22.

FIG. 9 is a diagram showing in more detail the display data execution processing unit 40 of the television 1 shown in FIG.

[0192] Each part of the control script execution unit 41 detects a predetermined event by the event processing unit 11 (for example, the display data requested as described above is supplied from the display data generation device 2). In response to notifying the display data execution processing unit 40 of a predetermined signal, the display data execution process (S11) shown in FIG. 5 is executed to process the display data 7 .

The control script analysis unit 140 analyzes the display data 7 shown in FIG. 3, in particular, the control script 110 included in the display data 7. For example, the control script analysis unit 140 analyzes the control script 110, extracts scripts related to the operation menu (operation menu specification script 122, operation function definition script 132, etc.), and the analysis result is the operation menu control unit 142. To communicate.

[0194] The slide show execution control unit 141 controls execution of various processes for executing a slide show of album photos. Specifically, the basic function execution unit 42 is controlled to generate the slide show display screen data in accordance with the layout definition script 112 and cause the display control unit 24 to draw the data. In addition, the basic function execution unit 42 is controlled to automatically play back the slide show or to display / hide a character string / graphic displayed on the photograph.

[0195] The operation menu control unit 142 controls display processing of an operation menu that lists items of functions of the television 1 (operations that can be performed by the television 1). Specifically, the operation menu data to be superimposed on the slide show display screen by controlling the basic function execution unit 42 is generated according to the operation menu specifying script 122 of the layout definition script 112 and drawn on the display control unit 24. Let

[0196] Note that each operation item constituting the operation menu specified by the operation menu specifying script 122 is associated with a function to be executed by the television 1 when it is selected. Each function corresponding to the operation item is defined by the operation function definition script 132, and is realized as one of the photo application functions by the control script execution unit 41 and the basic function execution unit 42 controlled by the control script execution unit 41.

An example of the operation function execution control unit is a photo rotation control unit 143.

The photo rotation control unit 143 controls the basic function execution unit 42 to execute a photo rotation 'display process according to the operation function definition script 1 32. For example, when the operation item “90 degrees to the right” is selected by the user, the photograph is displayed on the display unit 15 while being rotated 90 degrees to the right. [0199] The display control unit 24 draws a display area based on the display screen data notified from the control script execution unit 41, and the display screen defined by the display data is displayed on the television 1 on the display unit 15. indicate.

[TV display data execution processing flow]

FIG. 10 is a flowchart showing the flow of display data execution processing in the television 1. In FIG. 10, as an example, a flow of processing of the television 1 that displays the slide show display screen and executes the slide show by receiving the requested slide show display screen display data will be described.

[0201] Upon receiving a notification from the event processing unit 11 to start the display data execution processing, the control script analysis unit 140 follows the notification to display the received slide show display screen display data as a display data storage unit. The control script acquired from 51 and included therein is analyzed (S101).

[0202] The slide show execution control unit 141 executes a script (such as a layout definition script) for displaying the slide show display screen on the display unit 15 (S102). The display control unit 24 draws a slide show display screen according to the control of the slide show execution control unit 141 and displays it on the display unit 15 (S103). Thereby, the first drawing is completed, and for example, as shown in FIG. 11A, a photograph as the display object 111 included in the slide show display screen display data can be displayed. Here, an event standby state is entered (for example, button input by the user's operation unit 13) (S104). When the slide show is played automatically, as shown in FIG. 11A, the slide show execution control unit 141 displays an automatic frame advance icon 1101 indicating that according to the control script. To do. The slide show execution control unit 141 may display a photo title 1102, an operation method screen 1103, and the like according to the control script.

[0203] For example, during the initial drawing ((a) in FIG. 11), a yellow button (not shown) or a determination button (not shown) provided on the operation unit 13 is pressed by a user operation. Then, the signal is transmitted to the event processing unit 11 via the operation receiving unit 21, and the event processing unit 11 detects the event (YES in S104!).

[0204] Event processor 11 determines that the yellow button has been pressed (in S105) In step y), the control script execution unit 41 executes processing corresponding to the control script execution unit 41.

[0205] Here, the yellow button on the operation unit 13 is a button for operating the television 1 to display the operation menu 1104 ((b) in FIG. 11), and the operation menu 1104 is displayed. This button is used to operate the television 1 to close the operation menu 1104 and return to the state shown in FIG. Such correspondence between each button provided on the operation unit 13 and the function to be executed by the television 1 when the button is pressed is described in the operation content definition script included in the control script. ing.

[0206] When the control script execution unit 41 receives the notification from the event processing unit 11, when the yellow button is pressed, the control script execution unit 41 opens the operation menu 1104 to determine whether it is! / (S 106). .

[0207] If it is determined that the operation menu 1104 is not open (NO in S106), the operation menu control unit 142 identifies the operation menu of the control script 110 included in the slide show display screen display data. In accordance with the script 122, the operation menu 1104 having contents corresponding to the display data is displayed (S107). Specifically, the basic function execution unit 42 is controlled to transmit data to be displayed to the display control unit 24. As a result, the display screen of the display unit 15 transitions from (a) in FIG. 11 to (b) in FIG.

On the other hand, when it is determined that operation menu 1104 is displayed (YES in S106), operation menu control unit 142 closes displayed operation menu 1104 according to control script 110. As a result, the display screen of the display unit 15 transitions from (b) in FIG. 11 to (a) in FIG.

[0209] In S105, when the event processing unit 11 determines that the determination button has been pressed (in S105, k), the control script execution unit 41 executes processing corresponding thereto.

Yes

[0210] Here, when the determination button of the operation unit 13 is pressed in a state where any one of the operation menus 1104 is selected, the operation item has a sub operation menu. The button for operating the TV 1 to open the sub operation menu. For example, as shown in (b) of FIG. 11 and (c) of FIG. 11, when the determination button is pressed while the operation item 1105 indicating “Rotate photo” is selected, the operation menu control unit 142 displays the sub operation menu 1106. Alternatively, the selected operation item is displayed in the sub operation menu. If the user does not have a user (unless defined in the operation menu specific script), when the operation item is selected, the control script execution unit 41 corresponds to the operation item according to the control script 110. Execute the process. Furthermore, if any of the menus is not opened and the enter button is pressed, the slide show execution control unit 141 performs a slide show execution process.

[0211] More details are as follows.

[0212] Similar to S106, when the control script execution unit 41 receives the notification from the event processing unit 11, it determines whether or not the operation menu 1104 is opened when the determination button is pressed (S109). ).

If it is determined that the operation menu 1104 is not open (NO in S109), the slide show execution control unit 141 performs a slide show execution process (SI 10). Specifically, when the determination button is pressed while the display screen of FIG. 11A is displayed, the slide show execution control unit 141 displays the next display of the photo displayed on the display screen. Show slides to show photos in order.

[0214] On the other hand, when it is determined that the operation menu 1104 is open (YES in S109), the control script execution unit 41 sets the operation item of the opened operation menu 1104 when the enter button is pressed. It is determined which of these is focused (S111). The focused state means that the operation item is selected by the cursor. In this embodiment, only the display area of the selected operation item is distinguished from other operation items. Are displayed in different colors (for example, the operation item 1105 indicating “rotate photo”).

[0215] As shown in (b) of FIG. 11, when it is determined that the enter button is pressed while the focus is on the operation item 1105 indicating "rotate photo" (YES in S112), the next In addition, the control script execution unit 41 determines the opening / closing of the sub-operation menu and the focus position in the sub-operation item (S113).

[0216] Here, when it is determined that the sub operation menu 1106 is closed (A in S113), the operation menu control unit 142 follows the operation menu specifying script 122 to execute "Rotate photo". The sub-operation menu associated with the operation item indicating "is displayed (S11 4). (C) in Fig. 11 shows an example in which the sub operation menu 1106 of the operation item 1105 is displayed. ing.

[0217] On the other hand, focus on one of the operation items in sub-operation menu 1106 of operation item 1105 (for example, “rotate 90 degrees left” or “rotate 90 degrees right” as shown in FIG. 11C). If it is determined to be! /, (B in S113), the photo rotation control unit 143 controls the basic function execution unit 42 according to the operation function definition script 132 to execute the photo rotation process. (S115). For example, when the Enter button is pressed while the sub-operation item “Rotate 90 degrees left” is focused ((c) in FIG. 11), it is displayed in (c) in FIG. ! /, The photo rotation control unit 143 performs a process of rotating 90 degrees to the left with respect to the landscape photo 1107. Thus, as shown in FIG. 11 (d), the photograph is displayed on the display unit 15 as a vertically long photograph 1108 rotated 90 degrees to the left.

[0218] On the other hand, when it is determined that the operation item other than the operation item 1105 is focused, the operation item has a sub operation menu, and the sub operation menu is closed. In this case (NO in S112 and A in S116), the operation menu control unit 142 displays a sub-operation menu for the other operation items (S117). On the other hand, when the sub-operation menu of the other operation item is opened and any of the sub-operation items is focused (NO in S112 and B in S116), the control stub execution execution unit 41 Then, according to the operation function definition script 132, the function! /, Associated with the sub operation item is executed (S118).

[0219] If the operation item is an item having no sub-operation menu in S116, the control script execution unit 41 is associated with the operation item according to the operation function definition script 132! / Perform the function.

[0220] When the photo rotation control unit 143 displays the rotated photo after the photo rotation processing of S115, if the script "Close the operation menu after photo rotation processing" is included in the control script As shown in Fig. 11 (d), the rotated photo is displayed with the operation menu closed. If the script “Close the operation menu” is not included, the photo rotation control unit 143 displays the rotated photo while the operation menu is open as shown in FIG. .

12 to 15 show that each part of the control script execution unit 41 performs the display data execution process described above. It is a figure which shows the specific example of the control script referred when performing this.

[0222] The script 132a shown in FIG. 12 is included in the operation function definition script 132 shown in FIG. The script 132a describes what function should be executed according to the display state when the yellow button is pressed. The control script execution unit 41 (operation menu control unit 142) uses the force S to execute the processing of S106 to S108 described above with respect to the force S made to the script 132a.

[0223] The script 132b shown in FIG. 12 is included in the operation function definition script 132 shown in FIG. Script 132b executes any function depending on the display status of the main operation menu and sub-operation menu (sub-operation menu 1 106 in Fig. 11 (c)) when the OK button is pressed. Describes what should be done. More specifically, when the OK button is pressed, if the sub operation menu is not open, the sub operation menu is opened, and if the sub operation menu is open, the sub operation menu is hidden. It is described to switch and execute the function of the sub-operation item.

[0224] For example, in the script 132d, the photo rotation control unit 143 executes when any of the photo rotation sub-operation items (in the sub-operation menu 1106) is selected by pressing the enter button. A function to rotate the photo should be defined.

[0225] The control script execution unit 41 (the operation menu control unit 142 and the photo rotation control unit 143) can execute the processes of S113 to S118 described above in accordance with the script 132b.

[0226] The script 122a shown in FIG. 13 is included in the operation menu specifying script 122 shown in FIG. The description of the script 122a specifies the main operation menu 1104 (for example, (b) in FIG. 11) to be displayed according to the content of the currently displayed display screen. In the above script 132a (Fig. 12), when the yellow button is pressed, the function specified when the operation menu (g id = "menu") specified in the script 122a is displayed is defined! /

[0227] The script 122b shown in FIG. 13 is included in the operation menu specifying script 122 shown in FIG. The script 122b specifies the sub-operation menu 1106 of the operation item 1105 indicating “Rotate photo”. The operation function definition script 132 displays the sub operation menu (g id = "submenu2") specified in the script 122b when the OK button is pressed while the operation item 1105 is displayed! / The functions are defined! / [0228] Here, when the landscape photo 1107 shown in (c) of FIG. 11 is not to be rotated, the operation item 1105 of “Rotate Photo” as in the operation menu 1104 is set to the TV 1 (operation menu control). It is not desirable for part 142) to display. For example, the TV 1 does not have the function to rotate the photo in the first place! /,! /, The circumstances, and it is not appropriate to display the photo in the portrait orientation. It is assumed that the album creator (the owner of the photo) has U force S and wants to rotate! /, Because the orientation of the photo is already appropriate.

[0229] In such a case, an optimal operation menu specifying script 122 may be provided to the television 1 in accordance with a photograph (content of display data) that is a display object.

[0230] When there is a situation as described above, it is desirable to prevent the television 1 from executing the "rotate photo" function with the display data including the photo. In this case, the display data generating apparatus 2 can provide the control script including the script 122a ′ shown in FIG. 14 instead of the script 122a shown in FIG. At this time, the operation function definition script 132 of the control script may not include a script for the photo rotation function. Compared to the script 122a, the script 122a ′ shown in FIG. 14 does not include the operation item 1105 indicating “rotate photo”! /, And specifies the operation menu 1104 (FIG. 16)! /. According to such a script, the operation menu control unit 142 can display the operation menu 1104 on the display unit 15 as shown in FIG.

[0231] From the above, by providing the TV 1 with the optimal control script according to the content of the display data, the TV 1 always displays the optimal operation menu according to the display data. Touch with force S.

[0232] Furthermore, it is also possible to control the television 1 so that only a specific operation item in the operation menu 1104 is displayed in two steps as in the sub operation menu by appropriately changing the control script. For example, suppose that the ability to rotate a photo is not intended to actively use the photo rotation feature on the side providing the photo. In this case, an operation menu identification script is provided in which operation item 1105 is displayed in two steps in the same way as the sub operation menu only when an operation item of “Others” is provided in operation menu 1 104 and it is selected. 12 2 (Fig. 17 (a)) and operation function definition script 132 should be provided to TV 1. [0233] By providing the operation menu specifying script 122 and the operation function definition script 132 to the television 1, the operation menu control unit 142 causes the operation item 1105 to be the same as the sub operation menu 2 as shown in Fig. 17 (b). Stage display is possible. Also, the photo rotation control unit 143 has the power S Kurakura to execute photo rotation processing when such an operation item 1105 is selected.

[0234] Alternatively, when the control script for displaying the same operation menu 1 104 is provided to the television 1 regardless of whether or not the photograph can be rotated, the control script execution unit 41 performs the control. A configuration may be adopted in which it is determined whether or not the photograph can be rotated based on the script, and whether or not to display the “rotate photograph” sub-operation menu 1106 is displayed.

For example, the display data generation device 2 provides the television 1 with the script 132 b ′ shown in FIG. 15 instead of the script 132 b of FIG. Thus, the television 1 operates according to the script 1230 described to execute the subsequent processing only when the photograph can be rotated. That is, only when the control script execution unit 41 determines that the photograph can be subjected to the rotation process, the operation menu control unit 142 performs the sub-operation of “Rotate Photo” specified by the script 122b in FIG. Processing to display the menu 1106 is performed.

From the above, by providing the television 132 with the script 132b ′ shown in FIG. 15, the television 1 can display the sub-operation menu 1106 only when the photograph can be rotated.

Note that the slide show execution process executed by the slide show execution control unit 141 in S 110 shown in FIG. 10 can be controlled by the script 132c shown in FIG.

[0238] If the user presses the enter button on the operation unit 13 when the operation menu 1104 shown in Fig. 11B is not opened, the slide show execution control unit 141 further automatically plays the slide show. It is determined whether it is medium.

[0239] The slide show execution control unit 141 hides the automatic frame advance icon 1101 and displays the frame advance stop icon 1109 when the determination button is pressed while the slide show execution control unit 141 is in its own power S slide show automatic playback. At the same time, the automatic playback of the slide show is stopped. on the other hand If the enter button is pressed while the slide show playback is stopped, the frame advance stop icon 1109 is hidden, the automatic frame advance icon 1101 is displayed, and the slide show automatic playback is resumed. As described above, by providing the script 132c to the television 1, it is possible to realize the television 1 that controls the automatic playback of the slide show by pressing the enter button when the operation menu is not opened.

Next, details of the display data generation device 2 that generates display data including the control script as described above in response to a request from the television 1 and provides the television 1 with the display data will be described.

The operation item selection unit 83 selects an operation item (function of the television 1) to be included in the operation menu based on the determination result / analysis result output from the display target attribute determination unit 81 and the image analysis unit 82. Thereby, the control script for displaying the optimum operation menu corresponding to the contents of the display data (display screen) can be completed. In addition, the control script contains various operation items listed in the operation menu. Functions can be provided for TV 1.

[0281] The operation item selection unit 83 refers to the selection rule stored in the item selection rule storage unit 93, and adds an operation item to be added to the operation menu suitable for the display screen according to the determination result / analysis result. select.

FIG. 22 is a diagram illustrating an example of a rule table stored in the item selection rule storage unit 93 for the operation item selection unit 83 to select an operation item.

[0283] As shown in FIG. 22, in the rule table, each function that can be provided to the TV 1 by the description of the control script is listed in advance, and each function and various information about each function are indicated by function ID ( Stored in association with column C1).

[0284] "Function" in column C2 indicates the content of the function provided to the television 1 described above.

[0285] "Judgment method" in column C3 indicates the procedure of the judgment process for the requested photo or display data request message. Each of these determination processes is executed by the display target attribute determination unit 81, the image analysis unit 82, the operation item selection unit 83, and the like. The operation item selection unit 83 determines whether or not to add the operation item of the function to the operation menu according to the determination result.

[0286] “Selection shell IJ” in column C4 indicates that the operation item selection unit 83 sets the operation item of the function to the operation menu (or sub-operation menu) according to the determination result by the determination method shown in column C3. ) Shows the rules for determining whether or not to add. In column C4, for each “judgment result (if)” of column C41, “selection action (then)” (column C42) that defines actions to be taken by the operation item selection unit 83 is defined.

As described above, the operation item selection unit 83 selects an operation item to be added according to the determination result of the display target attribute determination unit 81 according to “selection shell IJ” in column C4.

[0288] Note that, without making any determination, information on columns C3 and C41 is not necessary for functions that are common to all display data and should always be provided (for example, functions 5 to 7). In this embodiment, functions 5 to 7 are defined in the selection rule as “always add to the operation menu”.

The selection result of the operation item selection unit 83 (for example, the function ID of the function selected by the operation item selection unit 83) is transmitted to the operation function definition generation unit 84 and the operation menu generation unit 85. [0290] Based on the function ID selected by the operation item selection unit 83, the operation function definition generation unit 84 is based on the operation function definition script 132 (Fig. 3) for causing the television 1 to execute the function. That is, the contents are extracted from the operation function storage unit 94 and embedded in the pattern data.

[0291] Based on the function ID selected by the operation item selection unit 83, the operation menu generation unit 85 generates an operation menu (operation menu specifying script 122 (Fig. 3)) including the operation item of the function. It is. Specifically, based on the function ID, the operation item name (text data indicating each operation item (contents) in the operation menu 1104 in FIG. 11 (b) is displayed) from the operation function storage unit 94. Extract and embed in pattern data.

[0292] In addition to embedding the above operation item name (contents), the operation menu generation unit 85 displays the operation position to be displayed when the operation item to be added is determined by the operation item selection unit 83. Calculate the size (start point Χ · Υ coordinates, width, height (contents)) and embed it in the pattern data.

[0293] As described above, the operation menu generation unit 85 may determine the display color of the operation menu or the display position of the operation menu based on the analysis result of the image analysis unit 82. Good.

[0294] As a method of determining the display color, for example, if the color of the entire photo is strong in red, select the blue system, or the color of the position where the operation menu is superimposed is strong in white V In this case, it is assumed that a black color is selected.

FIG. 23 is a diagram showing an example of a function table stored in the operation function storage unit 94. The function table stores information on the contents to be embedded in the pattern data.

[0296] As shown in FIG. 23, each function that can be provided to the television 1 by the description of the control script is listed in advance in the function table, and each function and various information about each function are stored in the function ID. It is stored in association. Unlike the rule table (Fig. 22), each type of information is also stored in association with each sub-operation item (functions 11 and 12) in the sub-operation menu.

[0297] "Operation item name" in column C5 indicates text data indicating each operation item in the operation menu 1104 in (b) of FIG. The operation menu generation unit 85 uses the text data (operation item name) in column C5 and the display position and display size information of each operation item as a pattern. Embed the operation menu specific script by embedding it in the data.

[0298] "Script" in column C6 indicates an operation function definition script that defines a predetermined process to be executed by the television 1 as a photo application function. As shown in Figure 23, scripts are prepared for each function. The operation function definition generation unit 84 embeds the script in column C6 in the pattern data, and completes the operation function definition script that combines the scripts prepared for each function into one.

[0299] In FIG. 23, the script of column C6 is shown in text for the sake of simplicity. However, the information that operation menu generation unit 85 actually extracts from column C6 and embeds in the pattern data is shown in FIG. As shown in the script 132b, it is composed as text data described in XML.

Note that the function table shown in FIG. 23 is an example for explanation, and does not limit the present invention. In addition to the functions shown in FIG. 23, the display data generating device 2 provides the TV 1 with all other functions (second function) that are executed when the TV 1 displays a photograph (first function). It is possible to provide.

FIG. 24 is a diagram showing a specific example of pattern data. FIG. 24 shows only the portion of the operation menu specifying script 122 generated by the operation menu generation unit 85 in the pattern data of the display screen ID “Scr_C” shown in FIG. The script 240 is a script template for specifying an operation menu, and the script 250 is a script template for specifying a sub operation menu.

[0302] In FIG. 24, the location where the operation menu generating unit 85 embeds the contents is indicated by "@ @ — * * *-@ @". Specifically, the replacement position 241 is the name of the operation item, the replacement position 242 is the display position of the operation item (starting Χ · Υ coordinates), and the replacement positions 243 and 244 are the display size of the operation menu ( (Width and height).

[0303] In this way, when the actual values specified by the operation function definition generation unit 84 are embedded in all the replacement positions, the operation menu specifying script 122 (Fig. 13) in the control script is generated.

FIG. 25 and FIG. 26 are diagrams showing specific examples of the operation function definition script generated by the operation function definition generation unit 84. The operation function definition generation unit 84 selects the operation item selection unit 83. Based on the result, the script is identified from the function table (column C6) of the operation function storage unit 94, and the operation function definition script for each function is completed. FIG. 25 shows a specific example of the operation function definition script that defines the “rotation function”. According to the operation function definition script in Fig. 25, when the photo rotation process is executed based on the script 132d in Fig. 12, the currently displayed photo is hidden and the rotation position is calculated. (The variable rotateno is calculated). Based on the calculated rotation position, the rotated photo is displayed (script 132d in FIG. 12), and the photo rotation function is realized. Figure 26 shows a specific example of the operation function definition script that defines the “comment display function”! The operation function definition generation unit 84 embeds the script of each function in the pattern data to complete one operation function definition script.

[0305] The script composition unit 86 stores various scripts (for example, the operation menu specification script 122 (Fig. 13) and the operation function definition script 132 (Fig. 12)) generated by each unit of the control script generation unit 80 described above. To create a control script. The control script generated by the script composition unit 86 includes a script for providing an appropriate function to the television 1 according to the content of the display data requested by the display data request message.

In the above example, only generation of the operation menu specification script 122 and the operation function definition script 132 from each component pattern data of the control script generation unit 80 has been described. However, the present invention is not limited to this. Each part of the control script generation unit 80 (not shown) embeds appropriate contents in the pattern data selected by the pattern data selection unit 61 to display the display object specifying script 121, the attribute information specifying script 123, and the state transition definition script shown in FIG. 131 is completed and supplied to the script composition unit 86.

The control script generated by the script composition unit 86 is supplied to the display data generation unit 62. The display data generating unit 62 generates display data by combining the control script acquired from the script combining unit 86 and the display object, and provides the generated display data to the requesting television 1 via the transmitting unit 63b.

Display objects specified by the display data generating unit 62 include album information, photo information, photos stored in the network album DB 8, and stored in the display object storage unit 92! /, Other images (such as the operation button images! For example).

[0309] Thus, the television 1 that has received the display data can display the requested display screen (for example, a slide show display screen) and control the display data during the display screen display. It is possible to execute a predetermined photo application function according to the script. The display data generating device 2 can change the control script as appropriate according to the content of the requested display data and provide it to the television 1. From the above, it is possible to easily change the function of the television 1 according to the content of the display data to be displayed.

[0310] Furthermore, when a new photo application function is added in the service of the network album system 100, it is desired that the function can be added to the television 1 after being distributed to the market. According to the display data generation device 2 of the present invention, a new function can be easily added to the television 1 simply by generating a control script and providing it to the television 1. For example, if a function to add effects such as photo fade-in to a slide show is added, simply write the function of the effect in the control script and add the corresponding operation item to the operation menu specific script. ,.

FIG. 27 is a flowchart showing in detail the flow of processing for generating display data (S3 to S8 in FIG. 5) in the display data generating apparatus 2.

[0312] When receiving unit 63a receives the display data request message (Fig. 7) from TV 1 (YES in S201), request message analyzing unit 70 analyzes the received display data request message ( S202). More specifically, the display target ID acquisition unit 71 acquires the album ID and the photo ID, the display screen ID acquisition unit 72 acquires the display screen ID, and the related information acquisition unit 73 receives the specification information ( Get the number of pixels on the screen).

[0313] Next, the pattern data selection unit 61 selects the optimum pattern data for generating the requested display data from the pattern data table of the pattern data storage unit 91 based on the display screen ID. (S203). Here, as an example, assume that pattern data for generating slide show display screen display data is selected.

[0314] The control script generation unit 80 generates a control script to be included in the display data based on the selected pattern data. The control script generation unit 80 first adds the album ID and Based on the photo ID, the photo as the display target stored in the network album DB8 is specified.

[0315] The display target attribute determination unit 81 acquires the photo information (Fig. 21) of the specified photo from the network album DB8 (S204).

[0316] Subsequently, the display target attribute determination unit 81 determines the attribute of the photograph based on the acquired photograph information and the specification information included in the display data request message (S205). Specifically, it is as follows.

[0317] (1) Judge whether the top and bottom of the photo is correct.

[0318] The display target attribute determination unit 81 uses the photo information table shown in FIG. 21 to determine whether the vertical direction of the photo is correct based on the value of the “vertical direction” (or “rotation function”) of the identified photo. (Whether or not the rotation function is necessary) is determined.

[0319] (2) The number of screen pixels of TV 1 is compared with the number of photographic pixels.

[0320] The display target attribute determination unit 81 compares the screen pixel number (R5) of the television 1 shown in FIG. 7 with the number of photographic pixels obtained from the “horizontal pixel number” and the “vertical pixel number” shown in FIG. Determine if the number of photographic pixels is smaller than the number of screen pixels!

[0321] (3) Judge whether or not there is a comment on the photo.

[0322] The display target attribute determination unit 81 determines whether or not a comment is stored in the "photo comment" shown in FIG.

[0323] (4) Judge the copyright protection information of the photo.

[0324] Based on the "copyright protection information" shown in FIG. 21, the display target attribute determination unit 81 determines whether or not the copyright protection locking force S is applied to the photo!

[0325] Next, the image analysis unit 82 acquires the specified photo from the network album DB8 and analyzes the photo (S206). More specifically, the color tone of the photograph is specified, and the display position of the subject is specified.

[0326] The operation item selection unit 83 selects an operation item (function provided to the television 1) to be displayed on the operation menu according to the determination result of the display target attribute determination unit 81 (S207).

[0327] If it is determined that the top of the specified photo is not correct according to the selection rule (column C4), the operation item selection unit 83 operates the rotation function operation item and its sub-operations. Decide to add the item to the operation menu. Only when the rotation function is necessary, the rotation function can be provided to the television 1.

[0328] Also, if it is determined that the number of pixels in the photo is smaller than the number of screen pixels on TV 1, select the operation item for the screen size switching function (the function to enlarge the photo and display it on the full screen size of TV 1). Add to the operation menu. Only when the size of the photo is smaller than the screen size of TV 1, the enlarged display function can be provided to TV 1.

[0329] If it is determined that a comment is attached to a photo! /, Te! /, An operation item of the comment display function is added. If it is determined that the copyright protection lock force is not applied to the photo, add the print function operation item to the operation menu. As a result, if the copyright protection lock is strong on the photo displayed on the display screen, the power S can be controlled to prevent the television 1 from printing.

[0330] The operation item selection unit 83 may be configured to select an operation item to be selected based on the content of the related information acquired by the related information acquisition unit 73. For example, in the display data request message, as related information, setting information (information for setting whether or not to display the operation method screen 1103 as shown in FIG. ))) Is included!

[0331] The operation item selection unit 83 determines the content of the setting information "operation method display", and if the operation method display is set to "Shin! /,"! /, The operation method display function Do not add the operation item of! / ヽ (or add it as a sub operation item of the operation item “Others”). On the other hand, when the operation method display is set to “Yes”, it is determined to add the operation item.

[0332] Thus, the operation method display function can be provided to the television 1 only when the requesting television 1 is set to "display operation method screen".

[0333] When the operation item (function) to be included in the operation menu is selected according to the item selection rule storage unit 93 in S207, the operation item selection unit 83 selects the function ID of the selected function as the operation function definition generation unit 84. And supplied to the operation menu generation unit 85.

[0334] Next! /, The operation function definition generation unit 84 is based on the function ID! /, The function table (FIG. 23) of the operation function storage unit 94, and the script of the column C6 (operation function Definition script) The operation function definition script is generated by embedding in the pattern data (S208). The operation menu generating unit 85 extracts the operation item name in the column C5 based on the function ID and embeds it in the pattern data to generate an operation menu specifying script (S209). At this time, the display size, display position, display color, etc. of the operation menu are calculated, and the calculation result is embedded in the pattern data.

[0335] The script synthesis unit 86 synthesizes various scripts generated by the respective units of the control script generation unit 80, and generates a control script (S210).

[0336] The display data generation unit 62 identifies all necessary display objects, extracts them from the network album DB8 and / or the display object storage unit 92 (S211), and generates the control script generated above. The data is synthesized to generate display data (S212).

[0337] The transmitting unit 63b transmits the display data generated by the display data generating unit 62 as a response to the display data request message of the television 1 (S213).

[0338] In the flowchart of FIG. 27, the case where the slide show display screen of one photo included in the album is generated is described. However, the slide show display screen of all the photos included in the album is generated continuously. May repeat the processing of S204 to S212 for each photo.

[0339] According to the configuration and method described above, the display data generation device 2 creates an optimal operation menu screen according to the display data requested by the television 1, and supports the operation menu operation items. This function is provided to TV 1 together with the screen data of the above operation menu. The television 1 that has received the display data can display the requested display screen (for example, a slide show display screen) and, while the display screen is being displayed, according to the control script for the display data. It is possible to execute a predetermined photo application function.

[0340] In other words, functions that can be executed by TV 1 by selecting the operation menu operation items to be displayed for each display data (display screen) displayed by TV 1 using a display data control script Can be customized.

[0341] As described above, by changing the control script and providing it to the television 1, the function of the television 1 can be easily changed. [0342] As a change related to the operation menu, the number of operation items on the operation menu is increased or decreased. Change the presence / absence of the sub-operation menu and the number of sub-operation items for a certain operation item. Change the operation item name as necessary. For example, changing the display position and display color of the operation menu.

[0343] Further, the television 1 can dynamically change the operation menu according to its own operation by following the control script.

For example, the operation menu control unit 142 (FIG. 9) responds to the operation of the slide show execution control unit 141 according to the operation of the operation item 1110 (FIG. 11) of the frame feed control operation item 1110 shown in FIG. In the example of (c), "Automatic frame advance start / stop") may be changed dynamically! /.

[0345] Prepare two types of text data for the operation item names to be displayed in the operation item 1110 part of frame advance control in the control script. The first shows the function to start automatic frame advance, the operation item name "Start automatic frame advance", the second shows the function to stop automatic frame advance, the operation item name "Auto frame advance" "Stop".

[0346] Furthermore, when the operation menu 1104 is displayed, it is specified that the operation item name "stop automatic frame advance" is displayed in the area of the operation item 1110 when the TV 1 is automatically playing a slide show. Prepare a script and a script that stipulates that the operation item name “Start automatic frame advance” is displayed when the TV 1 is in the automatic slide show stop mode.

[0347] As a result, the operation menu control unit 142, if the determination button is pressed while the slide show execution control unit 141 is performing the slide show automatic playback (when the operation menu 1104 is called), (a ), An operation menu 1104 including an operation item 1110a of “stop automatic frame advance” is displayed. On the other hand, when the slideshow execution control unit 141 is pressed when the slideshow automatic playback is stopped, as shown in FIG. 28 (b), an operation including the operation item 1110b of “Start automatic frame advance” is performed. Menu 1104 is displayed. In this way, the television 1 can dynamically change the display of the operation menu 1104 according to the control script described above.

[0348] Alternatively, display methods other than the operation menu can be controlled (automatic frame advance icon 1101, photo title 1102, operation method screen 1103, etc. shown in Fig. 11 (a)). . More specifically, an automatic frame advance icon indicating that automatic playback is in progress is added to the control script that defines a function that stops automatic playback of slideshows of photos in an album. A script may be added to instruct 1101 to be changed to a comma feed stop icon 1109 indicating that automatic playback is stopped.

[0349] Furthermore, the function of the television 1 can be easily changed by changing the behavior of the television 1 when a predetermined event is detected in the control script. For example, for the photo rotation function, you can add sub-operation items that can rotate the photo every 180 degrees instead of every 90 degrees, and control the time span during which one photo is automatically displayed in the slideshow. You may change arbitrarily using.

[0350] [Variation 1 Change the display order of operation items]

When generating the operation menu specific script for displaying the operation menu, the operation menu generation unit 85 of the display data generation device 2 determines the display order of the operation items based on a predetermined condition, and performs the operation in that order. It is possible to specify the operation menu so that the item is displayed.

[0351] For example, it is assumed that the display order of operation items is determined based on the frequency with which each function is used by the user.

[0352] Each time the television 1 executes a function provided from the display data generation device 2, the television 1 transmits menu usage information indicating that the function has been used to the display data generation device 2. The menu usage information includes a function ID for identifying the function used. In addition, the menu usage information includes the terminal ID of the TV 1, user information, and information on the date and time when the function was used!

[0353] The display data generation device 2 has a column for storing the number of uses for each function in the function table shown in FIG.

[0354] When the display data generation device 2 receives the menu usage information from the television 1, the request message analysis unit 70 obtains the function ID from the received menu usage information, and the function used on the television 1 is displayed. Is identified. A function usage count management unit (not shown) of the control unit 60 adds 1 to the usage count of the function specified in the function table of the operation function storage unit 94. In this way, the usage count is stored for each function (operation item). [0355] Then, when the operation menu generation unit 85 generates the operation menu specific script, the operation menu generation unit 85 stores the number of times of use for each operation item selected by the operation item selection unit 83. Read from 94. The operation menu generating unit 85 can generate an operation menu specifying script so that operation items are arranged in descending order of usage.

[0356] FIGS. 29 (a) and 29 (b) are diagrams showing examples of operation menu display before and after the display order of operation items is changed. As shown in (a) of FIG. 29, it is assumed that the television 1 has previously displayed the operation menu 1104 with the operation item 1105 indicating “rotate photo” at the top based on the control script. At this time, the operation item 1111 of “photo list display” is displayed third.

[0357] After that, the television 1 requests the display data generation device 2 again for the slide show display screen display data. The display data generation device 2 determines the display order of display items according to the frequency of use of each function at that time, and generates a new control script. At this point, assuming that the “photo list display” function is used most frequently by the user, the operation menu generation unit 85 of the display data generation apparatus 2 has the “photo list display” operation item 1111 as the first. Generate an operation menu specific script to be displayed above.

[0358] According to the new control script including the above operation menu specifying script, the television 1 sets the operation item 1111 of “photo list display” at the top as shown in FIG. 29 (b). The operation menu 1104 is displayed.

[0359] As described above, according to the number of times the user uses the function, the operation menu design is dynamically changed so that the operation item force selection selection position (for example, the upper part of the list) is used. It becomes possible. This makes it possible to always provide the user with an operation menu that allows easy selection of frequently used functions.

[0360] Alternatively, the display data generation device 2 may store the number of times a photo is requested from the user's television 1 and viewed for each photo in the album. As a result, the display data generating device 2 controls the display of the popular photos that are often viewed so that the photos are displayed prominently decorated or marked. Use the power S to generate script 卜.

[Variation 2—Focus move] If the control script is used, the operation menu control unit 142 (FIG. 9) of the television 1 can be operated as follows.

[0362] Specifically, the operation menu control unit 142 determines the focus position according to the information set in the television 1 and its own operation state according to the control script. Then, the cursor is placed at the determined focus position, and only the operation item is displayed in a conspicuous color (focus display processing).

FIG. 30 is a diagram showing a specific example of a control script for the television 1 to execute the focus display process. As shown in Fig. 30, when the (sub) operation menu is displayed in the control script, (1) read the setting information, (2) read the operation of the slide show execution control unit 141, (3) read It is stipulated that the cursor is placed on the (sub) operation item that matches the content, and (4) the (sub) operation menu is displayed by changing the display color of the (sub) operation item that the cursor is on! /

[0364] According to the control script, the television 1 performs the above-described operations (1) to (4).

[0365] Here, it is assumed that after the main operation item is selected, the sub-operation menu focus display processing is performed, and this will be described in more detail. The operation menu control unit 142 of the display data execution processing unit 40 first reads the setting information according to the control script of FIG. The setting information is setting information (column group C12) in the related information table stored in the related information storage unit 52 shown in FIG. To explain using the example shown in FIG. 8, the operation menu control unit 142 displays “comment display” = “Yes”, “operation method display” = “Yes”, “Repeat play” = “No”, “Frame”. The value “feed interval” = “10 seconds” is read from the related information storage unit 52.

[0366] Next, the operation menu control unit 142 reads the operation state of the slide show execution control unit 141, and determines whether or not the slide show automatic playback is in progress or stopped. Here, it is assumed that playback is in progress.

Subsequently, the operation menu control unit 142 specifies the (sub) operation menu to be displayed on the display unit 15 based on the operation menu specifying script. Then, an operation item that matches the content read above is determined, and the cursor is placed on the operation item.

[0368] The operation menu control unit 142 changes the display color of the operation item to which the cursor is placed and operates the operation menu. Display the menu.

[0369] (a) to (e) of FIG. 31 are diagrams illustrating examples of sub operation menus that the television 1 displays in focus based on the above-described control script.

FIG. 31 (a) shows an example in which the sub-operation menu of the operation item “comment display setting” is displayed. In the above example, the operation menu control unit 142 reads the value of “Comment display” = “Yes”, so the focus position is determined as the sub-operation item “Display photo comment” and the sub-operation menu is displayed. indicate.

[0371] (b) of FIG. 31 shows an example in which the sub-operation menu of the operation item “operation method display setting” is displayed. In the above example, the operation menu control unit 142 reads the value of “operation method display” = “Yes”, so the focus position is determined as the sub operation item of “display operation method” and the sub operation menu is displayed. Is displayed.

[0372] Fig. 31 (c) shows an example in which the sub-operation menu of the operation item of "repeat playback" is displayed. In the above example, the operation menu control unit 142 reads the value of “repeat playback” = “no”, so the focus position is determined as the sub-operation item of “no repeat playback” and the sub-operation menu is displayed. .

FIG. 31D shows an example in which the sub-operation menu of the operation item “Automatic frame advance interval” is displayed. In the above example, the operation menu control unit 142 reads the value of “frame advance interval” = “10 seconds”, so the focus position is determined as the sub-operation item of “frame advance at 10 second intervals”. Displays the sub operation menu.

FIG. 31 (e) shows an example in which the sub operation menu of the operation item “start / stop of automatic frame advance” is displayed. In the above example, the operation menu control unit 142 determines that “the slide show execution control unit 141 is automatically reproducing the slide show”, and therefore the focus position is set as a sub-operation item “start automatic frame advance”. Confirm and display the sub-operation menu.

[0375] In this way, by providing the above-described control script to the television 1, the television 1 can perform a predetermined operation that matches the content according to the information set in the television 1 and its own operating state. It is possible to display an operation menu in a state where the item is focused.

[Embodiment 2] [Background technology and issues]

Conventionally, for image display devices that handle and display large-capacity digital image data, the drawing process of drawing an image in an image buffer such as a VRAM and displaying it on the display unit has been a heavy process. To perform simple drawing processing faster

[0377] Therefore, in order to perform drawing processing at a higher speed, the hardware resources and their mechanisms are enhanced, or the amount of data handled is reduced to reduce the load of drawing processing. Ingenuity to speed up has been made.

[0378] For example, Patent Document 2 [Japanese Published Patent Publication: JP-A-6-149533 (published on May 27, 1994)] describes a segment drawing method having a double buffer in a segment out of the display area. A graphic display device and its high-speed drawing method are disclosed, which enables high-speed drawing processing by omitting processing for one buffer.

[0379] However, in the apparatus of Patent Document 2, even when the information is partially updated, all information (for all screens) must be redrawn, and unnecessary redrawing other than the portions that need to be redrawn is required. There was a problem that drawing processing occurred.

[0380] Therefore, Patent Document 3 [Japanese Published Patent Publication: Japanese Patent Application Laid-Open No. 11-65813 (published on March 9, 1999)] allows partial updating of information, and delays in drawing processing. A drawing processor for preventing is disclosed.

[0381] However, the device of Patent Document 3 calculates a redrawing area that requires application force redrawing built in the device. For this reason, the procedure for the device to calculate the redrawing area cannot be changed dynamically according to the contents of the information (display data), and a certain procedure is required for any redrawing of information. The redrawing area is calculated by. Therefore, for certain information, there is a problem when an area that is not intended by the information provider is included in the redrawing area and wasteful redrawing processing occurs!

[0382] Furthermore, if another information that does not need to be updated (particularly an object having a complicated shape) is partially included in such an unintended redrawing area, the redrawing area may be forced. Must be cut out (clipping process). At this time, part of it There is a problem that the more complicated the object to be drawn, the more the load on the device for clipping processing increases.

[0383] In addition, in the case of image display devices such as TVs and mobile phones, there are restrictions on the hardware resource design in the case of! /, Te! /, Te! / It is not practical to improve resources for speeding up the drawing process without considering them (such as constraints on the size of itself). In particular, it is desirable to realize the redrawing process more efficiently in an image display device such as a television in which the memory area is extremely limited.

[0384] Therefore, in this embodiment, in the display data control script, the display data is displayed in accordance with the contents of the display data (display screen) displayed on the television 1 (Figs. 1, 6, and 9). The optimum redrawing area. The optimum redrawing area means that the redrawing area is the minimum necessary without complicated processing. The television 1 can specify the optimum redrawing area in consideration of the contents of the display data according to the control script, and can efficiently perform the redrawing process. Considering the contents of the display data is not limited to this. For example, which object is updatable on the display screen, and the force at which the display position of the object is fixed moves. It is to consider whether or not.

[0385] The television 1 and the display data generation device 2 (network album system 100) that can designate the optimum redrawing area and execute the redrawing process efficiently will be described below.

[0386] [Control script (redraw control script)! /, Te]]

FIG. 32 is a diagram showing a specific example of the control script included in the display data (FIG. 3) of the present embodiment. In the control script of Fig. 32, a predetermined signal (for example, 'a') is input via the layout definition script 112 that specifies the display of three shapes of circle 'cloud' balloons and the operation unit 13. In this case, an operation content definition script 113 that specifies that the radius of the circle displayed above should be changed from 50 to 100 is displayed.

[0387] In the layout definition script 1 12, the above three figures are defined by being surrounded by tags ("ku" and '/>"! /) (Script 112a) and displayed on the display screen. The image data and text data (or audio / video data) to be processed are defined by a set of tags as described above. In the following description, this is referred to as an object regardless of the data format. [0388] As shown in (a) of Fig. 33, the television 1 displays the above three objects (circle 331, cloud 332, balloon 333) on the display unit 15 according to the layout definition script 112. It becomes the power S Kurakura.

[0389] Next, a redrawing control script for the television 1 of the present embodiment to specify an optimum redrawing area and efficiently execute the redrawing process will be described.

[0390] The redrawing control script constitutes a part of the above-described control script, and includes a redrawing area definition script 112b and a redrawing area change script 113b.

The redrawing area definition script 112b defines the area to be redrawn in a rectangular shape based on the start point (Χ · Υ coordinate) of the area and the width and height of the area. Note that the object in the redrawing area is an object for causing the television 1 to specify the redrawing area, and is not intended to be viewed by the user. Therefore, as shown in FIG. In part 15, the rectangle of the redraw area is not displayed. (The color is set !, N! /, ("None" specified), the display attribute "visibility" is displayed / hidden! /, Even if the setting is shifted, it is invisible to the user! /).

The redrawing area change script 113b acquires the redrawing area defined by the redrawing area definition script 112b, and defines a change process to be performed on the part. In the example shown in Fig. 32, the redrawing area change script 1 13b specifies that the hidden setting is changed to display when the signal 'a' is input (the change function "setTrait (" visibility ',' Visible '); In this way, by defining the change process in the redraw area change script 113b, TV 1 can determine whether the redraw area defined in the redraw area definition script 112b needs to be redrawn at an appropriate timing. Judgment can be made.

[0393] FIG. 33 (b) shows a state after TV 1 executes a change process according to operation content definition script 113 when a predetermined button of operation unit 13 is pressed and signal 'a' is input. 6 is a diagram showing a display example of the display unit 15. FIG. As defined in the operation content definition script 113, the circle 331 is displayed with its radius changed from 50 to 100.

[0394] If the above-described redrawing control script is described in the control script! /, If there is no change in the object (circle 331), the TV 1 will set the circumscribed rectangle ( The shaded area 334) within the broken line frame in FIG. 33C is specified as the redrawing area. If the object (cloud 332 or balloon 333) is partially included in the redrawing area, clipping processing (cutting out the part included in the redrawing area of the object) is performed. The calculation of this clipping region (the black part in (c) of FIG. 33) is more burdensome for the television 1 as the shape of the object is more complex.

[0395] In the present embodiment, when a change occurs in the circle 331, the television 1 has a rectangular area defined in advance by the above-described redrawing control stub (a hatched area in the dashed-dotted line frame in FIG. 33C). ) Is specified as the redrawing area. For this reason, the redrawing area includes the entire object (cloud 332 or balloon 333) (or does not include the entire object! /), So there is no need to perform clipping processing. As a result, the efficiency of the redrawing process on the television 1 can be increased.

[0396] As described above, the redrawing area of the redrawing area definition script is desirably defined so as not to partially include the object in order to avoid the clipping process of the object.

[0397] The display data generation device 2 that generates the display data (consisting of the control script and the display object) is used for all objects (graphics, photos, operation menus, text data, etc.) described in the control script. ) For the redrawing area, determine the redrawing area so that the redrawing area does not include the force including the whole object or the object at all (so that it does not include only part of the object). Generate a region specification script. In other words, the display data generation device 2 calculates the minimum necessary optimum redrawing area according to the content (position outside the object) of the display screen (display data) requested of the television 1, A control script for designating such a redrawing area is provided to TV 1.

[0398] Hereinafter, the configuration of the television 1 for performing redrawing according to the above-described redrawing control script will be described in more detail.

[0399] [TV configuration 2—Details]

FIG. 34 is a block diagram showing a main configuration of the television 1 according to the present embodiment. FIG. 34 is a diagram showing the display data execution processing unit 40 of the television 1 shown in FIG. 1 in more detail, as in FIG. 9 of the first embodiment.

In the television 1 shown in FIG. 34, the difference from FIG. 9 is that the control script execution unit 41 performs control. In addition to the script analysis unit 140 and the photo rotation control unit 143, a change detection unit 144, a redrawing region specifying unit 145, a clipping unit 146, and a drawing unit 147 are provided. This is the point that a storage unit 55 is provided.

[0401] Although not shown here, the control script execution unit 41 includes the slide show execution control unit 141 and the operation menu control unit 142 described above!

[0402] Further, as described above, the television 1 includes the temporary storage unit 18 and the frame buffer 19 configured by a volatile storage device such as a RAM.

[0403] Temporary storage unit 18 temporarily stores display data extracted from display data storage unit 51 and processed by each unit of display data execution processing unit 40.

[0404] The frame buffer 19 temporarily stores display screen data for one screen to be displayed on the display unit 15 generated after the processing of each unit of the display data execution processing unit 40 is completed. It is. The data on the display screen stored in the frame buffer 19 is drawn on the display unit 15 by the display control unit 24 and displayed so as to be visible to the user.

[0405] As described above, the control script analysis unit 140 analyzes the control script.

Hereinafter, the function of the control script analysis unit 140 will be described in more detail.

[0406] (About DOM tree)

In this embodiment, more specifically, the control script analysis unit 140 has a function of expanding a control script, which is an XML document, into a tree structure called a DOM (Document Object Model) tree. A DOM tree defines the logical structure of an XML document. By expanding the control script into the DOM tree, the data in the control script can be handled for each object described by the tag, and the relationship between the objects can be identified. The DOM tree has the advantage of being able to access the desired objects regardless of the order in which the control script is written.

[0407] For example, the control script shown in FIG. 32 is expanded like a DOM tree shown in FIG. Such a DOM tree output by the control script analysis unit 140 is expanded on the temporary storage unit 18 of the television 1 described above, and is read by each unit of the display data execution processing unit 40 as necessary.

[0408] The change detection unit 144 is a script (for example, specifying the change processing described in the control script. For example, a change function of the redrawing area changing script 113b) is detected to determine the necessity of the redrawing process for each object.

[0409] When the change detection unit 144 detects a change processing script describing a process of changing the object being displayed and determines that the object needs to be redrawn, the change detection unit 144 sets a change flag to the object on the DOM tree. Stand up. The change flag is set to indicate that the object needs to be redrawn.

[0410] In the control script shown in FIG. 32 and FIG. 35, the change detection unit 144 uses the rectangle identified by ID = 'updatearea, (the hatched part in (c) of FIG. 33 defined in advance as the redrawing area). The circle identified by ID = 'circle' (circle 331 in Fig. 33 (a)) is detected as an object that needs to be redrawn. Therefore, the change detection unit 144 sets the change flag 341 for the rectangular object “rect” and the circle object “circle” in FIG.

[0411] The change detection unit 144 detects not only the above-described change function, but may also detect, for example, an object of the OKI function. If the object can be detected by changing the object, the object to be changed can be detected under any conditions.

[0412] The redrawing area specifying unit 145 acquires information on the object for which the change detecting unit 144 has set the change flag from the temporary storage unit 18, and specifies the redrawing area.

[0413] Specifically, the redrawing area specifying unit 145 stores the DOM tree stored in the temporary storage unit 18.

(Fig. 35) is scanned to obtain the redrawing area of all objects for which the change flag 341 is set. A list of the redrawing areas acquired by the redrawing area specifying unit 145 is referred to as a redrawing area list. The redrawing area specifying unit 145 generates a redrawing area list and stores it in the redrawing area information storage unit 55. If the object has a circle or other complicated shape, a circumscribed rectangle area including all of the object is calculated, and the calculated rectangle is added to the list as a redrawing area of the object.

[0414] When all the redrawing areas are added to the list based on the DOM tree, the redrawing area specifying unit 145 scans all the redrawing areas listed and merges them into one if there are overlapping areas. To do. That is, the circumscribed rectangle of all the redrawing areas that overlap is calculated.

[0415] Fig. 36 (a) shows an example of a redrawing area list stored in the redrawing area information storage unit 55. It is a figure. An example of the redrawing area list generated by the redrawing area specifying unit 145 based on the control script shown in FIG. 32 and FIG. 35 is shown.

[0416] The redrawing area list is generated for each control script constituting one display screen. In the example shown in Fig. 32 · Fig. 35, since the change flag 341 was set for the rectangular object "rect" and the circle object "circle", the redrawing area of these two objects was added to the list. Yes. In the redrawing area list, the redrawing area of the object is associated with the control script ID for identifying the control script in FIGS. 32 and 35 and the object ID for identifying the object in the control script. Information (Χ / Υ coordinates, width, height, which is the starting point of the rectangle) is stored.

[0417] When the redrawing area specifying unit 145 lists the redrawing areas of all the objects for which the change flag is set, the redrawing area specifying unit 145 then merges the overlapping redrawing areas. Finally, one redrawing area (or multiple if it does not overlap) is confirmed and specified as the confirmed redrawing area.

FIG. 36 (b) is a diagram showing an example of confirmed redrawing area information stored in the redrawing area information storage unit 55. An example in which the redrawing regions in FIG. 36 (a) are merged is shown. Since the redrawing areas listed in the example of FIG. 36 (a) overlap as shown in FIG. 33 (c), the circumscribed rectangular area 334 of the circle 331 in FIG. The rectangular area 335 defined by the drawing control script is merged, and one fixed redrawing area is calculated. Note that multiple confirmed redrawing areas can be calculated by one control script, so each redrawing area can be managed by the redrawing area ID.

In this way, the confirmed redrawing area output from the redrawing area specifying unit 145 is supplied to the drawing unit 147 that executes redrawing processing on the confirmed redrawing area.

[0420] The drawing unit 147 redraws the confirmed redrawing area specified by the redrawing area specifying unit 145. The clipping unit 146 performs clipping processing.

[0421] Specifically, first, the drawing unit 147 reflects the result of the change processing for the change target object (the object for which the change flag 341 is set) in the fixed redrawing area, and the temporary storage unit 18 Write to.

[0422] Next, the drawing unit 147 scans the DOM tree, and at least part of the drawing redrawing area falls within the fixed redrawing area. If there is an object other than the change target that is included, get the script that defines the object. This is because as long as an object that has not been changed is included in the fixed redrawing area, the changed information cannot be correctly displayed unless the drawing is redrawn. If the entire object is included in the fixed redrawing area, the object is written in the temporary storage unit 18 based on the acquired script! /.

[0423] On the other hand, when the acquired object is partially included in the confirmed redrawing area! /, The clipping unit 146 calculates the portion of the object included in the confirmed redrawing area. Then, it is returned to the drawing unit 147 as a clipping region. The drawing unit 147 writes the clipping region acquired from the clipping unit 146 in the temporary storage unit 18.

[0424] The redrawing area specified by the redrawing control script is the object as described above.

The display data generation device 2 can be defined according to the content of the display data so as not to partially include (particularly those having complicated shapes). Therefore, the fixed redrawing area calculated by the television 1 does not include a complicated shape, and a heavy clipping process can be avoided.

[0425] Thereby, all the objects that need to be redrawn in the fixed redrawing area are written in the temporary storage unit 18. Finally, the drawing unit 147 draws the data of the fixed redrawing area after the change process written out to the temporary storage unit 18 in the frame buffer 19 and saves the corresponding fixed redrawing stored in the frame buffer 19. Update the data in the area before the change process. Then, the redrawing of the confirmed redrawing area is completed, and the new information after the change is displayed on the display unit 15.

[0426] According to the above configuration, when the display data including the redrawing control script for designating the redrawing area is received by the television 1, the initial display screen is first displayed according to the display data control script. . After that, when the change detection unit 144 detects that the displayed information has changed, the redrawing area specifying unit 145 specifies the fixed redrawing area according to the redrawing control script included in the control script. To do. The drawing unit 147 displays a new display screen in which the redrawing area specifying unit 145 specifies and redraws the confirmed redrawing area to reflect the change.

[0427] Here, the redrawing area specified by the redrawing control script does not require complicated processing. In addition, the minimum necessary redrawing area is defined in advance according to the contents of the display data. That is, the confirmed redrawing area specified by the television 1 in accordance with such a redrawing control script does not partially include objects. As a result, it is only necessary to redraw only the minimum necessary area while avoiding clipping of the object, and as a result, the redrawing process can be executed efficiently.

[0428] In addition, since the redraw area is specified by the control script, the optimum redraw area can always be specified by TV 1 according to the contents of the display data. It is possible to avoid the processing load and always perform the redrawing process efficiently.

[Redrawing process flow]

FIG. 37 is a flowchart showing the flow of the redrawing process in the television 1. In the redrawing process, the control script of the display data is analyzed by the control script execution unit 41 (Fig. 34) (expanded into a DOM tree) and executed. After the initial screen is drawn, a predetermined event is displayed. When detected by the event processing unit 11, it is executed by each unit of the control script execution unit 41.

[0430] The redrawing process consists of three main steps. That is, the step of determining the necessity of redrawing from the redrawing area changing script, the step of redrawing area specifying unit 145 identifying the redrawing area from the redrawing area definition script, and the drawing This is a step in which the part 147 redraws the specified redrawing area.

[0431] Details of each step will be described below.

[0432] When the event processing unit 11 detects a predetermined event during the initial screen display (YES in S301), the control script execution unit 41 determines that the event processing unit 11 has the currently expanded DOM tree (control According to the script), the display data is processed (S302). When the change detection unit 144 detects a redrawing area change script such as a change function (or an animation object) in the control script being executed (YES in S303), the change detection unit 144 sets a change flag to the detected change target object. Stand up (S304). At this time, there may be one or more change target objects detected! /.

[0433] Next, the redrawing area specifying unit 145 generates a redrawing area list for each object based on the change target object detected by the change detection unit 144. [0434] First, the redrawing area specifying unit 145 scans the DOM tree of the above-described control script developed in the temporary storage unit 18, and sequentially acquires objects (S305). If the change flag is set on the acquired object (YES in S306), the redrawing area of the change target object is calculated and added to the redrawing area list (S307). Here, if the object area is defined by a rectangle, it is listed as it is. If it is defined by a shape other than the rectangle, the circumscribed rectangle of the object is calculated and listed. The processing from S305 to S307 is executed for all objects on the DOM tree.

[0435] Finally, the redrawing area specifying unit 145 scans each redrawing area added to the redrawing area list, merges any redrawing areas that overlap, and finally finalizes the redrawing area. Is output to the drawing unit 147 (S308).

[0436] Next, the drawing unit 147 writes all the objects included in the specified final redrawing area to the temporary storage unit 18, and uses display data for drawing in the frame buffer 19. .

[0437] First, the drawing unit 147 scans the DOM tree expanded in the temporary storage unit 18, and sequentially acquires the objects (S309). It is determined whether or not even part of the acquired object overlaps the fixed redrawing area (S310). If it is determined that the object overlaps the fixed redrawing area (YES in S310), it is next determined whether or not the acquired object is a change target object having a change flag (S311).

[0438] If the drawing unit 147 determines that the object is a change target object (YES in S311), each part of the control script execution unit 41 executes a change process on the change target object according to the change script. (S312). Then, the changed object obtained by the changing process is written in a predetermined area of the temporary storage unit 18 (S313).

[0439] On the other hand, if it is determined in S311 that the acquired object is not the object to be changed (NO) (NO), the drawing unit 147 then enters the final redrawing area of the object. It is determined whether the partial force overlaps only a part or the whole (S314). If it is determined that the entire acquired object overlaps the fixed redrawing area! / (S3 In NO at 14), the acquired object is directly written in a predetermined area of the temporary storage unit 18 (S315). On the other hand, if it is determined that the acquired object partially overlaps the fixed redrawing area (YES in S314), the clipping unit 146 has a portion where the fixed redrawing area of the object overlaps (clipping Area) is calculated (S316). Then, the drawing unit 147 writes the clipping region of the acquired object in a predetermined region of the temporary storage unit 18 (S317). The processing from S309 to S317 is executed for all objects on the DOM tree.

[0440] Finally, the drawing unit 147 redraws the data of the confirmed redrawing area after the change, which has been written, from the temporary storage unit 18 to the confirmed redrawing area of the frame buffer 19 (S318). Then, the redrawing of the fixed redrawing area is completed, and the new information after the change is displayed on the display unit 15.

[0441] As described above, the redrawing area specified by the redrawing area definition script does not require complicated processing and is defined in advance as the minimum necessary redrawing area according to the content of the display data. It is a thing. That is, the confirmed redrawing area specified by the redrawing area specifying unit 145 according to such a script does not partially include the outside of the object having a complicated shape. This makes it possible to redraw only the minimum necessary area while avoiding clipping of objects with complex shapes. As a result, the redrawing process can be executed efficiently.

[0442] Since the redrawing area is specified by the control script, the optimal redrawing area can always be specified by TV 1 according to the content of the display data. It is possible to avoid the processing load and always perform the redrawing process efficiently.

[0443] As described above, specifying the redrawing area on the display screen in advance with the control script results in a display screen containing many complicatedly shaped objects, and a lot of processing changes depending on the event. This is particularly effective for the display screen.

[0444] In the following, it is possible to redraw only the minimum necessary area while avoiding the tarbing process of an object having a complicated shape by using the display screen examples of Figs. 38 (a) to (i). A specific example of the redrawing area specified so that it can be performed will be described. TV 1 specifies the fixed redrawing area according to the redrawing area (redrawing area definition script) specified in (i) of FIG. For example, it is possible to perform more efficient redrawing processing that does not require the load S of clipping processing compared to the case where the fixed redrawing region is specified by the redrawing region calculated for each object that needs to be changed. .

[0445] FIGS. 38A to 38D are diagrams showing specific examples of a display screen that is displayed on the display unit 15 and includes an object having a complex shape. In addition, the correspondence between the changes that occur between the display screens in (a) to (d) of FIG. 38 and the event that triggers the change is shown with an arrow.

[0446] (e) to (h) in Fig. 38 are (a) → (b), (c) → (d), (a) → (c), (b) → (d) in Fig. 38, respectively. ) And the confirmed redrawing area specified when the display screen is changed. Here, the confirmed redrawing area shown in (e) to (!) Of FIG. 38 is the redrawing area calculated for each object that needs to be changed when there is no redrawing area definition script. Show the confirmed redraw area specified by! /.

[0447] (i) of Fig. 38 shows the confirmed redrawing area specified in accordance with the redrawing area definition script.

[0448] Fig. 38 (a) is a display screen that displays the weather (four events) for a given time of the day and the forecast of the current temperature 'precipitation probability'. The display data is processed first. This represents the initial screen displayed. The cursor 381 indicates the weather forecast for the four times of the day. Of the four weather forecast icons 382, the forecast icon for the future is the closest to the future from the time when the initial screen is displayed. Focus on. The background cloud (object of complicated shape) 383 is a display screen design, and is always placed behind the various types of weather forecast information (all objects) on any screen. Each weather mark 384 in each weather forecast icon 382 is also an object having a complicated shape that takes a load S for clipping processing.

When the yellow button provided on the operation unit 13 is pressed during the display of FIG. 38 (a), the display screen changes from FIG. 38 (a) to the display screen of FIG. 38 (b). That is, the detailed information balloon 385 at 12:00 is displayed. Therefore, as shown in (e) of FIG. 38, an area 380e that is a circumscribed rectangle of the detailed information balloon 385 is specified as the fixed redrawing area.

If the right cross button provided on the operation unit 13 is pressed during the display of FIG. 38 (a), the display screen changes to the display screen of FIG. 38 (c). That is, from the weather forecast icon 382 at 12:00, Weather forecast icon 382 The cursor 381 moves. Therefore, as shown in (g) of FIG. 38, an area 380g that is a circumscribed rectangle of the above-described two weather forecast icons 382 is specified as the fixed redrawing area.

[0451] Similarly, when there is no redrawing area definition script, the circumscribed rectangle of each object that has changed is specified as the fixed redrawing area, so each fixed redrawing area (area 380e 380h) Both display screens partially include objects with complicated shapes such as background clouds 383 and weather marks 384, and as a result, high-load clipping processing must be executed.

[0452] Therefore, as shown in (i) of Fig. 38, an object having a complicated shape may be included in the whole or not at all, and the minimum necessary area. Specify the redrawing area in the redrawing area definition script. As a result, according to the redrawing area definition script, the television 1 can specify the optimum fixed redrawing area that does not partially include the object having a complicated shape as shown in the area 380i.

As a result, it becomes possible to avoid the clipping process and execute the redrawing process efficiently.

[Variation 3—Redrawing when rotating a photo]

In the above example, the power of the control script designating the redrawing area so that it does not partially include objects with complex shapes avoids clipping processing and allows TV 1 to efficiently execute redrawing processing. I explained!

[0455] However, the control script is not limited to the above example. Control script so that an object placed at a given display position is always subject to redrawing processing regardless of the complexity of the shape and whether or not that object is the object to be changed. It is also possible to specify a redrawing area with.

[0456] As described above, as the situation where it is necessary to specify the redrawing area in accordance with the display area of the object, specifically, the following situation can be considered.

[0457] When changing the display screen, the data of the display screen that is actually output to the display unit 15 due to hardware restrictions, that is, the storage capacity of the temporary storage unit 18 is extremely limited. There is a situation in which the area reserved for storing the data (hereinafter referred to as the ARGB area) must be used to temporarily store the data generated during the change process.

[0458] In such a situation, before the display screen data to be output to the display unit 15 is drawn in the ARGB area, the area (dirty area) used in the change process in the ARGB area is cleared. There must be.

[0459] However, it is not sufficient to clear the dirty area. If an object was originally placed in the area before the change, such an object (not the object to be changed) Also need to be redrawn and restored. Therefore, as described above, it is necessary to specify the redrawing area so that the objects involved in the change process (objects that overlap the area stained in the process of change process) are also redrawn properly.

[0460] The following is an example of change processing (S312 in Fig. 37) force photo rotation processing (S115 in Fig. 10). Accordingly, the television 1 that executes the redrawing process according to the control script designating the redrawing area will be described.

[Problems when rotating a photo]

(Configuration of temporary storage)

FIG. 39 is a block diagram showing a main configuration of the television 1 (particularly the temporary storage unit 18) that executes the photo rotation processing. As described in the first embodiment, the photo rotation / display processing is executed by the photo rotation control unit 143 according to the control script. More specifically, the photo rotation control unit 143 uses the temporary storage unit 18 as a work area, acquires the photo to be rotated from the display data storage unit 51, rotates the acquired photo, and rotates it. This photo is sent to the frame buffer 19, and the rotated photo is displayed on the display unit 15.

The temporary storage unit 18 used as a work area by the photo rotation control unit 143 has an ARGB area 181, a spare area 182, and a YUV area 183. The above three areas are fixed by hardware in the temporary storage unit 18.

[0463] The YUV area 183 is an area for temporarily storing J / PEG photographs received in the YUV format and stored in the display data storage unit 51! /.

[0464] ARGB area 181 and spare area 182 are YUV types stored in YUV area 183 This area is used to temporarily store JPEG photos of the formula converted to ARGB format.

[0465] The ARGB area 181 is an area for storing display screen data that is actually output to the display unit 15. The display screen data output to the frame buffer 19 is always supplied from the ARG B area 181. The spare area 182 is a spare area that is used as a work area when the control script execution unit 41 executes a change process such as rotation on the photograph after being converted into the ARGB format.

[0466] Note that the YUV format is a format that expresses color using three types of information: luminance signal (Y), the difference between the luminance signal and the blue component (U), and the difference between the luminance signal and the red component (V). That's it. Since a larger amount of data is allocated to the luminance information, a high data compression rate can be obtained with little degradation in image quality. This has the advantage of adopting the YUV format.

[0467] Therefore, when the display data generator 2 provides the display data with the display data, the photo is always in the YUV format. Therefore, since it is necessary to convert to RGB format (to ARGB format) for display on the display unit 15, the photograph is developed in the YUV area 183 by the control script execution unit 41 and then converted to ARGB format. After being expanded into the ARGB area 18 1 or the spare area 182, it is sent to the frame buffer 19.

[0468] (Status of ARGB area and spare area when rotating a photo)

Next, the state of the ARGB area 181 and the spare area 182 when the photo rotation control unit 143 rotates the photo when the appropriate redrawing area is not specified by the redrawing area definition script included in the control script. The problem in this case is described below with reference to FIG.

FIG. 40 (a) shows the state of the ARGB area 181 and the spare area 182 at the time of initial drawing.

The ARGB area 181 stores display screen data currently displayed on the display unit 15 (circle object 190, portrait 185, background). Nothing is stored in the spare area 182. Or some data may remain in the course of another task

Here, when an instruction to rotate the portrait photo 185 by 90 degrees is input, the photo rotation control unit 143 executes photo rotation processing. Therefore, first, as shown in Fig. 40 (b), the ARGB area Call up portrait 185 converted to ARGB format in area 181 and save it temporarily in ARGB area 181. Next, as shown in FIG. 40 (c), a picture obtained by rotating the vertically stored portrait photograph 185 by 90 degrees is temporarily stored in the spare area 182 as a horizontally long photograph 186. Thereafter, as shown in FIG. 40 (d), the dirty area 188 of the ARGB area 181 (that is, temporarily used in the rotation process) is cleared. Thereafter, the photo rotation control unit 143 specifies the redrawing area, redraws the display screen after the change (after the rotation), and redraws it.

[0471] At this time, if the redrawing area definition script is not specified, according to the above-described flow, the television 1 can display the area before the rotation of the photograph (vertical photograph 185) as shown in FIG. 40 (g). And the area after rotation (landscape photo 186) are specified as redrawing areas, and the circumscribed rectangle of each of these areas is specified as the fixed redrawing area (fixed redrawing area 184)

[0472] When the confirmed redrawing area 184 is specified, as shown in (e) of FIG. 40, the photo rotation control unit 144 stores the landscape photograph 186 temporarily stored in the spare area 182 with ARGB. Write to area 181. Then, the photo rotation control unit 143 detects the circular object 190 that partially overlaps the confirmed redrawing area 184 specified as described above. Then, as shown in (f) of FIG. 40, the clipping region 187 of the circle object 190 that the clipping unit 146 cut out to be redrawn is written in the ARGB region 181. The display screen data saved in this ARGB area 181 is output to the frame buffer 19 and displayed on the display unit 15.

[0473] In this way, unless the redrawing area is specified so as to include the entire circle object 190 in the redrawing area definition script, as shown in FIG. And the circle object 190 must be displayed, but the left side of the circle object 190 is displayed without being restored, and the photo rotation process cannot be performed correctly.

[0474] In order to solve the above problem, it is necessary to change the control script supplied to the television 1. Specifically, as shown in the dirty area 188 shown in FIG. 40 (d), all areas that overlap with the contaminated area are based on the areas that will have a component if they become dirty in advance by a predetermined process! Specify the redrawing area that includes the entire outside of the object with the redrawing area definition script. [0475] In this embodiment, since the called photo is always drawn from the upper left, the dirty region 188 can be identified from the start point coordinates (X, Y) = (0, 0) and the size of the photo. is there. That is, a control script that designates the area 189 as a redrawing area is supplied to the television 1.

FIG. 41 is a diagram showing an example of a control script in which a redrawing area is designated according to the circle object 190 and the area 189 used in the photo rotation process. The redrawing area definition script 112c is a script that designates the area 189 as a redrawing area, and the redrawing area change script 113c is used for causing the change detection unit 144 to recognize the designated redrawing area as a change target object. It is a script.

[0477] Photo rotation processing flow

FIG. 42 is a flowchart showing the flow of photo rotation processing executed by the photo rotation control unit 143 as the change processing in S312 of FIG. Note that the redrawing area specifying unit 145 specifies the area 189 in (i) of FIG. 40 as the confirmed redrawing area in S308 of FIG. In addition, the object determined as the change target object in S311 of FIG. 37 is hereinafter referred to as a rotation target photograph.

[0478] The photo rotation control unit 143 determines whether the rotated data of the photo to be rotated is stored in the spare area 182! /, (S401), and is stored! /, Na! /, In the case (NO in S401!), It is next determined whether or not the rotation target photo is stored in the YUV area 183 (S402). If the photo rotation control unit 143 determines that the YUV format photo to be rotated is saved in the YUV area 183 (! In S402! /, YES), it is saved! /, The photo to be rotated is converted from YUV format to ARGB format and developed in ARGB area 181 (S404). On the other hand, if it is determined that the rotation target photo is stored in the YUV area 183 (NO in S402), the photo rotation control unit 143 is stored in the display data storage unit 51. The rotation target photograph to be rotated is written in the YUV area 183 (S403), and the step of S404 is executed.

[0479] Next, the photo rotation control unit 143 draws the rotated photo obtained by rotating the rotation target photo stored in the ARGB area 181 by the amount determined by the control script in the spare area 182. (S405), and returns to the determination of S401.

[0480] In S401, the rotated data of the rotation target photo is stored in the spare area 182. If it is determined (YES), the photo rotation control unit 143 clears the fixed redrawing area specified by the redrawing area specifying unit 145 in the ARGB area 181 (S406).

[0481] Finally, the photo rotation control unit 143 writes the rotated target photo that has been temporarily stored in the spare area 182 in the ARGB area 181 (S407), and ends the photo rotation process.

[0482] After that, as already described in Fig. 37, other objects included in the confirmed redrawing area other than the rotation target photo (in the example of Fig. 40 (a) to (i), the circular object 190) If there is, it is written in the ARGB area 181, and the confirmed redrawing area updated in the ARGB area 181 is output to the frame buffer 19.

[0483] As described above, even if the temporary storage area (ARGB area 181) where the display screen data should be saved must be used in the process of change processing, An optimal control script that specifies a redrawing area that includes all the areas that overlap and the object that overlaps the dirty area may be generated according to the content of the display data and provided to the television 1.

[0484] According to the redrawing area specified by the control script, TV 1 can correctly identify the object that needs to be redrawn and fi redraw it even if it is an object other than the object to be changed. .

[0485] From the above, even when the storage capacity of the temporary storage unit 18 is extremely limited, it is possible to realize a television 1 that can perform display processing by changing digital image data with a large capacity. It becomes possible.

[0486] Note that the above description assumes that the photo format is JPEG. The format that can be displayed on the TV 1 is not limited to JPEG. Various formats such as bitmap and PNG are available. Format photo · Images may be displayed. Also, if the rotation processing is applicable or not depending on the format, the photo rotation control unit determines the format of the photo to be rotated, and executes the photo rotation processing only for photos in a format that can be rotated. Make up 143! /

[Variation 4-Redrawing process during preloading]

In the above example, the content of the display data (for example, the area that gets dirty by An example of partially specifying the area to be redrawn according to the object to be involved was described. However, the redrawing area definition script for designating the redrawing area is not limited to this, and a redrawing area definition script for designating the entire screen as the redrawing area can be provided to the television 1 as necessary.

[0488] As described above, when the television 1 acquires the display data (first display data), the first control script included in the first display data is expanded in the DOM tree and written to the temporary storage unit 18. (Preload). When displaying the display data for the first time, since there is no previous drawing data, the entire screen is drawn regardless of the redrawing area.

[0489] After that, when the first display screen is changed, only the fixed redrawing region that is the difference from the previous drawing data is redrawn by the above-described configuration and method.

[0490] However, even if a second display screen different from the above is displayed according to another display screen, that is, the second control script of the second display data, the DOM tree of the first control script Therefore, a situation occurs in the television 1 that the data is still stored in the temporary storage unit 18.

[0491] In such a situation, when the pre-loaded first display data is displayed once, then the second display data is displayed, and the first display data is displayed again, the redrawing area It may be judged that there is no. This is assumed when the change script (animation object, change function, etc.) detected by the change detection unit 144 is not included in the first control script of the first display data. Alternatively, even if such a change script exists in the first control script, it is assumed that only a part of the entire screen is specified as the redrawing area.

[0492] As described above, when it is determined that there is no redrawing area or only a part of the redrawing area is determined, an event for returning from the second display screen to the first display screen occurs. Despite detection, the display screen does not transition from the second display screen to the first display screen, or only a part of the display screen returns to the first display screen. The inconvenience of not occurring.

[0493] In such a case, it is necessary to designate the redrawing area for the full screen so that the full screen returns from the second display screen to the first display screen. [0494] Therefore, when processing display data on a display screen different from the display screen that has been displayed so far, a redrawing area definition script that makes the redrawing area the entire screen is included in each control script, and the TV 1 To provide.

[0495] As a result, when the event processing unit 11 detects an input of a signal instructing to return to the first display screen that has been displayed from the currently displayed second display screen on the TV 1. The control script execution unit 41 identifies the entire screen as a fixed redrawing area and redraws the entire screen of the first display screen according to the first control stub for displaying the first display screen. Therefore, even when returning to the original display screen from a different display screen, the screen transition can be performed correctly.

[0496] As described above, the redrawing control script is described in the control script according to the content of the display data and provided to the television 1 so that the display data creator (display data generator 2 ) Can be used to specify the intended redrawing area. By describing it in the control script, you can specify the area that you want to always update, or remove the area that you do not want to update from the specified.

[0497] With respect to the animation object detected by the change detection unit 144 as a change target, the redrawing area required when the object moves is controlled so that the television 1 can specify the circumscribed rectangle of the object. A script may be described.

[0498] Also, the shape of the redrawing area is not limited to a rectangle! /. Any simple figure that does not require complicated clipping processing can be used. For example, a redrawing area having a shape such as a hollow rectangle, a circle, or an ellipse like a frame may be defined in the control script.

[Embodiment 3]

In the description of the first embodiment, the control script is generated according to the content of the display data, the operation menu to be displayed is changed as appropriate, and the photo application function corresponding to the operation menu is provided to the television 1. I explained that.

[0500] Each photo application function provided to the television 1 by the control script is described in an operation function definition script such as the scripts 132a to 132d in Fig. 12 included in the control script, for example. In the operation function definition script, when (event definition), what to do, (to be executed Function definition) is described. As described in the first embodiment, by changing the definition part of the function to be executed according to the content of the display data, the photoablation function of the television 1 can be flexibly changed.

[0501] As shown in FIG. 12, the definition of the function to be executed is associated with the definition of an event that triggers the TV 1 to execute the function. In many cases, these events are detected by the event processing unit 11 when various buttons provided on the operation unit 13 are pressed by the user. For example, script 132a contains

iilevt.data == y)

Therefore, the function for displaying / hiding the operation menu defined by the script 132a is executed when the yellow button ('y' indicates the signal input by the yellow button) on the operation unit 13 is pressed. It is shown that. In other words, the yellow button (event) is associated with the function for displaying / hiding the operation menu!

[0502] In this embodiment, the operation of the television 1 operated by the operation unit 13 is controlled by appropriately setting the combination of the button (event) and the function of the operation unit 13 in the operation function definition script. Will be described. As a result, different functions can be assigned to the same button for each display data, and the same function can be assigned to different buttons for each display data.

[0503] In the display data generation device 2 that generates the control script, the optimal combination of these buttons and functions is selected according to the content of the display data when the control script is generated. In other words, no matter what display data is displayed on the TV 1, the operation function definition script is always generated in consideration of the user's operability, so the user's operability on the TV 1 must be maintained. Is possible.

[0504] Further, the display data generation device 2 may generate an operation function definition script by changing the combination of the button and the function in response to a request from the television 1. For example, TV 1 sends an instruction to display data generation device 2 so that what has been executed in response to the yellow button can be executed in response to the OK button (user power TV You can do that for 1). Based on the instruction, the display data generating device 2 associates the above functions with the enter button instead of the yellow button, Create a rip-up with force S.

FIG. 43 is a diagram showing an example of the operation function definition script. The script 431 defines an event “when the enter button (of the operation unit 13) is pressed”. 'k' indicates a signal input by the decision button.

[0506] Further, in script 431 and later, functions to be executed by the control script execution unit 41 of the television 1 when the enter button is pressed are defined. Here, as an example, when the TV 1 detects that the enter button is pressed while the display screen of FIG. 11B is being displayed, the operation menu control unit 142 displays the display screen of FIG. That is, sub-operation menu 110

The function to display 6 is defined! /

Here, script 431 of the operation function definition script shown in FIG.

iilevt.data == d)

It is assumed that the display data generation device 2 provides the television 1 with the changed information. In this case, the television 1 displays the sub operation menu 1106 when the right cross button that is not the enter button is pressed. 'd' indicates a signal input by the right cross button.

[0508] As described above, in the operation function definition script, the combination of the button and the function is changed, that is, by changing the definition of the event, the television 1 is executed so that the same function is executed by inputting different buttons. Can be controlled.

[0509] Note that the television 1 can display a display screen different from the currently displayed display screen according to the pressed button in accordance with the state transition definition script (screen transition). In the state transition definition script, transition destination information that defines which display screen to transition to when an event occurs is described. Therefore, in the state transition definition script, for example, the combination of the button and the transition destination information may be changed as follows.

[0510] (a) and (b) of FIG. 44 are diagrams showing the transition of the display screen when the enter button is pressed.

[0511] As shown in FIG. 44 (a), when the TV 1 detects that the enter button is pressed while the album history screen 440a is displayed, the slide show display screen 440b (initially the title screen of the album) Is acquired and displayed. On the operation method screen 1103 of the album history screen 440a, press the enter button to switch to the slideshow display screen 440b (title screen). Let's do a display to explain.

[0512] In this case, in the state transition definition script, the enter button and the slide show display screen

Transition destination information for transitioning to 440b is associated.

[0513] As shown in (b) of Fig. 44, when the television 1 detects that the enter button is pressed while the album history screen 440a is displayed, the television 1 acquires and displays the thumbnail display screen 440c. In this case, unlike (a) of FIG. 44, on the operation method screen 1103, a display explaining that the display is changed to the thumbnail display screen 440c by the OK button may be performed.

In this case, unlike (a) of FIG. 44, in the state transition definition script, the determination button is associated with the transition destination information for transitioning to the thumbnail display screen 440c.

[0515] Thereby, even if the same button is pressed, the display screen on which the television 1 is changed can be changed.

[0516] Furthermore, it is possible for the television 1 to describe a state transition definition script so that the transition destination changes according to a predetermined condition when the same button is pressed. In the example shown in (a) and (b) of FIG. 44, for example, when an album is selected with the enter button on the album history screen 440a by using a state transition definition script that describes conditions, the selection is performed. According to the number of photos included in the album, it is possible to realize the television 1 that determines whether to shift to the slide show display screen 440b or the thumbnail display screen 440c of the album.

FIG. 45 is a diagram showing a specific example of the state transition definition script when conditions are described.

This state transition definition script is assumed to be associated with the decision button. The state transition definition script shown in Fig. 45 is necessary for the control script execution unit 41 of TV 1 to make a condition determination, determine the transition destination according to the condition, and display the transition destination display screen. The following information is described.

[0518] Script 451 defines a method for obtaining information to be determined (here, the number of photos in the selected album). In accordance with the script 451, the control script execution unit 41 acquires the number-of-photographs information of the selected album from a predetermined file (top.svg). In the present embodiment, the file is created so as to indicate a value of “10” if the number of photos in the album is 10 or less and “11” if the number of photos is 11 or more. The above file can be identified by the name “top.svg” as long as it is described in the same control script along with the state transition definition script. The file is created by the display data generating device 2. Specifically, the display data generating device 2 refers to the album information table shown in FIG. 20 and includes a value of “10” or “11” in the above file according to the number of photos of the requested album. To create the above file.

[0519] The script 452 defines a method for determining the information to be determined (here, the number-of-photograph information acquired from the file). The control script execution unit 41 determines whether the number-of-photograph information is “10” or “1 1” according to the script 452.

[0520] Script 453 defines the judgment condition. In the example shown in FIG. 45, the function to be executed by the control script execution unit 41 is defined separately for the case where the number-of-photograph information is “10” and “11”. cpm_title "," cpm.thumbnail ") is defined! /

Yes

[0521] The script 454 defines a function to be executed by the control script execution unit 41 in accordance with each determination condition. That is, the control script execution unit 41 (1) acquires and displays the slide show display screen 44 Ob in accordance with “scripted cpmjitle” when the photo number information is “10” (10 or less), and (2) When the number-of-photograph information is “11” (11 or more), the thumbnail display screen 440c can be acquired and displayed according to the scripted “cpmjhumbnail”.

[0522] Therefore, by defining a condition and a function for each condition and writing a state transition definition script, when one button is pressed, it can be selected from a plurality of actions according to a predetermined condition. It is possible to control the television 1 to select and execute an appropriate operation.

[0523] As described above, the correspondence between various operation buttons provided on the operation unit 13 and the functions of the television 1 assigned to the buttons can be easily changed using the control script.

[Embodiment 4]

If the control script is used, the following functions executed by the television 1 can be controlled.

(1) Control of the display data acquisition function The television 1 transmits a display data request message for requesting desired display data to the display data generation device 2 and acquires the requested display data from the display data generation device 2.

[0525] It is possible to control the display data acquisition function of TV 1 by defining on the display data generation device 2 side which display data is to be acquired in the control script.

[0526] For example, it is assumed that after the first display data of the first display data is displayed, the second display screen of the second display data is always displayed. At this time, if the control script for the first display data describes that the second display data is to be acquired, the television 1 follows the control script and the first display screen for the first display data. And the second display data can be acquired.

Here, it takes a certain time for the television 1 to request display data from the display data generation device 2 via the communication network and to obtain the requested display data. Therefore, if an instruction to display the display data is received from the user and the display is started after the process for obtaining the display data is started, the user's convenience cannot be answered quickly. Is damaged.

[0528] Therefore, when the display screen (display data) to be displayed next can be predicted, the television 1 performs the next second display while processing the first display data according to the control script described above. Obtain data in advance. Thus, when a user instruction is input, it is possible to immediately display the next display screen based on the display data acquired in advance and stored in the own device. As a result, it is possible to increase the response speed of the display data display processing and maintain user convenience.

(2) Controlling the display data management function

The television 1 manages display data acquired from the display data generation device 2 in the display data storage unit 51. Specifically, according to the event detected by the event processing unit 11, the display data is stored in the display data storage unit 51 or deleted from the display data storage unit 51 determined to be unnecessary.

[0529] The control script defines how to manage the display data. Thus, the display data management function in the display data storage unit 51 of the television 1 can be controlled. For example, the acquired display data is stored so as not to be deleted from the display data storage unit 51, or when the display data is processed (displayed) a predetermined number of times, the display data is displayed. It is defined that the data is deleted from 51 or predetermined display data stored in the display data storage unit 51 is deleted.

[0530] As described above, since it takes a certain time to acquire the display data from the display data generation device 2, the display data frequently used (displayed) is stored in the display data storage unit 51. It is preferable to preserve it.

[0531] Therefore, when the display data generation device 2 sends display data frequently used in the television 1 to the television 1, the display data is not deleted from the display data storage unit 51. Provide a control script that defines what is stored in

[0532] The television 1 can always store frequently used display data in the display data storage unit 51 according to the control script described above, reducing the amount of communication with the display data generating device 2, The response speed of the display data display process can be increased.

[0533] The display data generation device 2 counts the usage frequency used in the television 1 for each display data, determines the display data storage method according to the usage frequency, and generates a control script. do it. Each time the television 1 uses (displays) the display data, it transmits the display data usage information to the display data generation device 2. The display data generating device 2 can accumulate the display data usage information sent from the television 1 and manage the usage frequency for each display data.

[0534] The configuration for generating the control script according to the usage frequency of the display data generation device 2 is described in the section of [Modification 1 Change display order of operation items] in the first embodiment. Since the configuration is the same as that described above, the description thereof is omitted here.

[Embodiment 5]

[Modification 5—Addition of visual and auditory effects during thumbnail / slide show display] In the network album system 100 of the present invention, the display data generation device 2 further supplies the control script to the television 1, thereby further providing the television 1. The following functions can be added to. In other words, the contents of the display screen that TV 1 is displaying (album • A function that outputs visual effects and auditory effects according to photos.

[0536] When the television 1 displays the album, the control script generation unit 80 of the display data generation device 2 further performs visual (and auditory) effects according to the album (or photo 'video) to be displayed. It is possible to generate a control script that defines the operation to output effects and sound so as to output. An effect is a visual effect to be attached to an object (for example, an album photo displayed in a slide show) when the object is displayed (or hidden). Specifically, various effects such as fade-in (out), slide-in (out), enlargement, and blinking can be considered. In addition, animations such as moving around the screen for objects other than photographs (such as characters), zooming, panning, and scrolling of characters are also included in the effects.

In the present embodiment, for example, as shown in FIG. 20, in the album information table, audio file information is managed for each album, and effect information is managed for each photo.

[0538] The column of "audio file name" indicates the file name of the audio file associated with the album. Audio files are used for output as audio (music, sound effects, etc.) when TV 1 displays thumbnails or slide shows for albums.

Yes

[0539] The "Effect ID" column indicates an effect ID for identifying an effect associated with each of the photos included in the album. The display data generating device 2 describes the operation of the television 1 related to the effect in the control script so that the television 1 executes the effect specified by the effect ID.

[0540] Fig. 46 is a block diagram showing a main configuration of the display data generating device 2 that generates display data to which visual and auditory effects are added. 18 differs from the display data generation device 2 in FIG. 18 in that the control script generation unit 80 further includes a voice specific script generation unit (control script generation unit) 87 and an effect definition script generation unit (control script generation unit) 8 8 The storage unit 90 further includes an audio file storage unit (effect information storage unit) 95 and an effect information storage unit (effect information storage unit) 96. .

[0541] The voice specific script generation unit 87 generates a voice file to be output together with the album display. The voice specific script including the link information is generated. The effect definition script generation unit 88 generates an effect definition script that can be executed by the television 1 based on the effect definition information stored in the effect information storage unit 96.

[0542] The audio file storage unit 95 stores an audio file. The audio file is stored in a file format that can be processed by the television 1 such as a midi format. The television 1 acquires the audio file from the display data generation device 2 and outputs it to the audio output unit 17 via the audio output control unit 25 (FIG. 1).

[0543] Alternatively, the display data generation unit 62 may include an audio file in the display data 7 and supply it to the television 1.

[0544] The effect information storage unit 96 stores effect definition information for defining an effect. FIG. 47 is a diagram showing an example of the effect definition script stored in the effect information storage unit 96.

[0545] In the example shown in Fig. 47, six columns are prepared for each effect.

[0546] "effectID" in column C21 indicates the above-described effect ID. Column C22 shows the name of the effect. For example, the effect name “FiU-opacity” means an effect that changes the opacity of an object (here, a photo).

[0547] "dur" in column C23 indicates the time (here, seconds) to apply the effect. For example, if it shows 3 seconds, it means that the effect (change in opacity) takes 3 seconds.

[0548] "from" in column C24 indicates the initial value of the object. Specifically, it shows the opacity of the photo before applying the effect. If "from" is shown as "0.8", it means that the photo starts to be displayed with an opacity of 0.8. In addition, it shows that it is transparent, so that the value of opacity is small.

[0549] “to” in column C25 indicates the final length of the object. In other words, it shows the opacity of the photo after the effect is applied for “dur” seconds. If "to" is shown as "0", it means that the photo is changed to 0 opacity.

[0550] “end” in column C26 indicates a key (button) to which a function for interrupting the operation of the effect on TV 1 is assigned. The “end” value is displayed on the control unit 13 of the TV 1 shown in FIG. One of the provided keys is specified. While the TV 1 is executing an effect, when the key of the operation unit 13 specified by “end” is pressed, the TV 1 interrupts the execution of the effect.

[0551] For example, assuming that the effect with the effect ID "effect00" shown in FIG. 47 is applied to the photo, the television 1 displays the slideshow according to the content of the effect definition script. It is possible to change the opacity from 0.8 to 0 over 3 seconds. Until then, if the “y” button (yellow button) is pressed by the user's operation, the effect can be interrupted.

[0552] In the example shown in Fig. 47, the power of three types of effect definition scripts is not limited to this, and various types of effect definition scripts can be stored!

[0553] The television 1 can execute the above-described operation in accordance with the operation function definition script 132 described in the operation content definition script 113 (Fig. 3).

[0554] Next, the operation of the display data generation device 2 that generates a control script with visual and auditory effects added will be described in detail. Hereinafter, a case where the display data generation device 2 generates display data 7 for slide show display in response to a request from the television 1 will be described as an example. However, the present invention is not limited to this, and display data 7 to which visual and auditory effects are added may be generated even in the case of thumbnail display.

FIG. 48 is a flowchart showing a flow of processing for generating display data of the display data generating apparatus 2 in the present embodiment. 48 differs from FIG. 27 in that the speech synthesis slivet generation unit 87 of the control script generation unit 80 generates the audio identification script before the script synthesis unit 86 performs synthesis in S210, and the effect definition script The generation unit 88 generates an effect definition script, and the display data generation unit 62 extracts an audio file in addition to the display object in S211. Note that S20 ;! to S213 are the same as the processing of FIG. 27 except that the extracted audio file is also combined with the display data, and therefore description thereof will not be repeated here.

FIG. 49 schematically shows an example of the layout definition script 112 ′ and the layout definition script 112 included in the pattern data 171 and the control script 110 stored in the pattern data storage unit 91 in the present embodiment, respectively. FIG. In the present embodiment, in the pattern data 171 acquired from the pattern data storage unit 91 by the pattern data selection unit 61 of the display data generation device 2, the layout definition script 112 ′ further includes an image identification script 274, an album basic Contains information 275 and voice specific script 279. Further, the image specifying script 274 includes an effect pattern 274a that is a template of an effect in association with the slide photograph.

Note that the image specifying script 274 (284) and the sound specifying script 279 (289) are specific examples of the display object specifying script 121, and the album basic information 275 (285) is the attribute information specifying script 123. It is a specific example.

[0559] Following S209 (Fig. 48), the control script generation unit 80 embeds an audio file name (that is, link information of the audio file) in the audio specification script 279 shown in Fig. 49, so that the audio specification script 289 Is generated (S209a). The audio file name to be embedded is extracted from the album information table stored in the network album DB 8 based on the album ID (and photo ID) already acquired by the display target ID acquisition unit 71. If you decide to display the slideshow of the first photo of the anomaly ID “01254782 25142584” (see Figure 20), the control scribing section 80 extracts the audio file name “bgml.midi” based on the album ID and embeds the link information to the audio file in the audio specifying script 279. Based on the audio specifying script 289 generated thereby, The TV 1 can acquire the audio file “bgml.midi” from the display data generation device 2 and play it back during the slide show display.

Next, the control script generation unit 80 generates effect definition script 284a by embedding effect attribute information in effect pattern 274a (S209b).

FIG. 50 shows a specific example of effect pattern 274a and effect definition script 284a shown in FIG. The parts between “@ @ —” and “— @ @” correspond to the effect attribute information (column C 2;! To C26) in the effect definition script table shown in FIG. In other words, the control script generation unit 80 extracts the six attribute information of the specified effects from each column and embeds them in the part of “@ @ — * * * — @ @” to generate the effect definition script 284a. . [0562] A specific description will be given using the example of Fig. 20 described above. Based on the TV 1 display data request message, it has been decided to display the first photo (photo ID = NO. 1) of the anomaly ID “01254782 25142584” as a slideshow. And The control script generation unit 80 specifies an effect based on the album ID and the photo ID. In the above example, since the effect ID “effectOO” is associated with the album ID and the photo ID, the effect of “100.00” is specified as the effect to be added to the photo.

Subsequently, the control script generation unit 80 extracts effect attribute information from each column of the effect definition script table of the effect information storage unit 96 based on the identified effect ID. The control script generation unit 80 generates the effect definition script 284a by embedding the extracted attribute information in the corresponding part. The effect definition script 284a in FIG. 50 describes changing the opacity of the white square to be superimposed on the target photograph from 0.8 to 0 over 3 seconds. When the yellow key (key (y)) of the operation unit 13 of the television 1 is pressed, the change process interruption function is assigned to the yellow key so as to interrupt the change process.

[0564] Finally, the display data generation unit 62 synthesizes the control script 110 generated by the control script generation unit 80 with the display object 111 (slide photo) and other objects (such as an audio file). To generate display data 7.

[0565] From the above, when the television 1 acquires the display data 7, the television 1 can display thumbnails and slide photographs in accordance with the control script 110 including the voice specifying script 289 and / or the effect definition script 284a. It can be presented to the user with auditory and / or visual effects. Specifically, in S11 of FIG. 5, when the effect definition script 284a is described in the slide show display data, the television 1 displays a photo by the method defined in the effect definition script 284a. .

[0566] In the present embodiment, the control script 110 can specify the timing for starting the effect processing. For example, in the above-described example, an effect is added to the display / non-display of a photo, so that the control script 110 describes the time when the photo is switched as the start timing of the effect processing. Or on the thumbnail display screen If you want to zoom in on the thumbnail image while the cursor is on one thumbnail image, the control script 110 may define the effect processing start time as the cursor position. it can.

[0567] Further, as described above, if the effect process is described using the control script 110, the target to which the effect is added can be specified for each object. As a result, it is possible to limit the range to which the effect processing is added only to the range of the object that is not on the entire screen. Therefore, compared to the case where the effect processing is performed on the entire screen, the load on the effect processing of TV 1 can be greatly reduced.

[0568] Note that in the slide show display data, the voice specifying script 289 may not be included in all the display data for each photo. For example, the voice identification script 289 is included only in the display data for displaying the first photo, and the control script 110 is described so that it is continuously played back when displaying subsequent photos. It is possible.

[0569] In addition, as described above, in this embodiment, the display data generation device 2 associates the event with the yellow key depression event with the effect definition script 284a. It is described in. As a result, the user can perform the key operation to interrupt the effect processing at an arbitrary timing.

[0570] If effects are processed during the processing of slide show display data, the load on TV 1 increases, and the response to the user's key operations becomes slow, resulting in a lack of operability. This is because the CPU load for effect processing is generally large.

[0571] However, according to the above configuration, the television 1 interrupts the effect processing when the yellow key is pressed, and immediately displays the target photo. Therefore, it is possible to omit the effect processing that the user does not want, to reduce the load on the television 1, and to improve the processing efficiency of the television 1.

[0572] Note that the event that triggers the interruption process is not limited to pressing the yellow key. For example, the control script generation unit 80 may describe the script so as to interrupt the effect processing with “when the GUI screen of the operation menu is called” as a trigger.

[0573] Also, when the function to call (display) the GUI screen of the operation menu is assigned to the yellow key, "When pressing the yellow key" is set as a condition for interrupting the effect processing. As a result (end = "accessKey (y)"), as a result, the GUI screen of the operation menu is called. The script is written to interrupt the effect processing with “when it is released” as a trigger.

[0574] In addition, if there is a key operation instructing the transition to the next slide or the previous slide even during the effect processing, the stub is described so that the effect is interrupted and the transition is made to the specified slide immediately. Also good.

[0575] Further, when the user does not wish to execute the effect processing, the user may display a GUI screen configured to select the presence / absence of an effect from the operation menu. In this case, if the user selects no effect, the script is written so that the television 1 does not execute the etaf process from the beginning.

[0576] Alternatively, the control script 1 can switch the presence / absence of an effect with a simple operation of pressing the key provided on the operation unit 13 of the television 1 without calling the operation menu.

10 may be described.

[0577] FIG. 51 is a diagram showing a specific example of the control script 110 including the operation function definition script 132 that defines the operation of the television 1 so as to switch the presence / absence of the effect according to the user's key operation.

In the example shown in FIG. 51, the control script 110 includes an effect definition script 284b, an operation function definition script 132e that controls the execution of the effect definition script 284b, and an operation function definition script 132e according to the user's operation. It includes an operation function definition script 132f that defines the operation for switching the contents.

[0579] In the operation function definition script 132e, when the processing of the display data 7 is initialized, the effect definition script 284b defines the effect flag power;! "Defined in the script. It is defined to execute the effect.

[0580] The operation function definition script 132f defines an operation for switching the effect flag when the blue key (key (b)) of the operation unit 13 is pressed.

[0581] According to such a control script 110, the television 1 can switch the presence / absence of an effect in response to the user's pressing of the blue key.

In the example in FIG. 51 described above, the description of the force control script 110 configured to control the presence / absence of an effect by changing the attribute “visibility” of the effect definition script 284b. The description method is not limited to this. For example, the television 1 can invalidate the effect according to a script describing an operation for changing the value of the attribute “display” of the effect definition script 284b to “none”. In this case, the television 1 can perform drawing at a higher speed than the drawing processing of the entire SVG related to the visibility attribute.

[0583] In the above description, the case where the effect 'sound is applied when displaying a still image such as a photograph has been described. However, the present invention is not limited to this. It is also possible to apply the effect 'sound to the moving image.

[0584] In the above description, the force described in the case where one effect process is defined for one object is not limited to this. It is possible to describe a plurality of types of effect definition scripts in the control script 110 in advance for one object. As a result, the user can add the effect to the object by simply selecting the effect from the menu! /, And select the desired effect with the above-mentioned multiple types of effects. Become.

[0585] For example, two types of animation (effects) on the theme of spring for a character are prepared for boys and girls and defined in the control script 110. Then, according to the script, the television 1 can add and display the animation selected by the user from the above two types of animation to the character.

[0586] In the present embodiment, the effect definition script table is displayed as a data generation device for display.

2 has the power to include the effect definition script in the display data 7 and supply it to the television 1. However, the present invention is not limited to this. The same effect can be obtained even if the TV 1 has the effect definition script table. That is, the display data generation device 2 associates the effect I with the photo as a script indicating which effect is added to which photo.

You only need to describe D.

[0587] Based on the effect ID included in the display data 7, the TV 1 refers to its own effect definition script table, adds an appropriate effect to the appropriate photo, and presents it to the user. Can do.

[0588] In this way, a diversified album that can be enjoyed by individual users according to user preferences. Network album system capable of providing video content.

[Variation 6—Character display processing when effect is enabled]

When the television 1 adds an effect by the above-described method and displays the photos of the album as a slide show, the character display processing may be performed in addition to the processing of drawing the photo while adding the effect processing. The character display process is a process for displaying the text data included in the display data 7 so as to be superimposed on the photograph.

FIG. 52 is a diagram showing an example of a slide show display screen displayed on the display unit 15 of the television 1. As shown in FIG. 52, in addition to displaying photos when the slide show display screen is displayed, operation information 152 indicating the remote control operation guide, playback status display 153 indicating the slide show playback status, photo title 154, Also, comment 155 added to the photo is displayed. These characters are described as text data in the layout definition information of the display data 7 and are displayed by the television 1 processing the display data 7. The text data is not limited to the above.

[0591] The character display process described above is a process in which the load is relatively high as in the effect process.

Therefore, when the television 1 performs the slide show display process in which the effect is enabled, the television 1 must execute both the effect process and the character display process every time the slide is drawn. In this case, due to the load of character display processing, the added effect processing may not be performed smoothly, and the response to key operations from the remote control (operation unit 13) may deteriorate, impairing user convenience. It might be.

[0592] Therefore, in this embodiment, a device for distributing the load applied to the TV 1 and smoothing the operation of the TV 1 in the slide show display process when the effect is valid will be described.

[0593] [Control script for load balancing]

In the present embodiment, when the slide show is displayed, the execution timing of each process in the TV 1 is controlled using the control script so that the TV 1 is not executed simultaneously with the effect process and the character display process. Specifically, if the effect is enabled, write it in the control script to start the character display process after the effect process ends. FIG. 53 is a diagram showing a specific example of the control script 110 that defines the operation of the television 1 to start the character display process after the effect process is completed.

[0595] In the example shown in Fig. 53, the control script 110 includes an operation function definition script 132g, a jet definition definition script 284b, and a display object specifying script 121a.

[0596] The display object specifying script 121a is a character specifying script that specifies text data to be displayed.

[0597] The operation function definition script 132g describes a script for instructing execution of character display processing and a script for defining the execution timing. Specifically, the operation function definition script 132g defines the operation of the television 1 so that the characters of the display target specifying script 121a are displayed when the effect processing of the effect definition script 284b is completed. .

[0598] Note that the end of the effect processing defined by the script is the effect processing.

1S It may be the time when it is executed to the end, or it may be the time when it is interrupted by a user operation.

[0599] When both the effect processing and the character display processing must be executed according to the control script 110, the television 1 executes the effect processing first, and after that, the character display processing is executed. Can be executed. In other words, it is possible to disperse time-consuming processes with heavy loads. As a result, the load is not concentrated at one time, so the added effect processing cannot be performed smoothly, or the inconvenience such as poor response to key operations from the remote control (operation unit 13) can be solved. It becomes possible.

[0600] It should be noted that the power described with the effect processing and the character display processing as an example of processing with a large load to be time-distributed is not limited to this. The display data generation device 2 can describe in the control script 110 the execution timing of any heavy processing that is preferably not executed simultaneously with the effect processing. For example, the display data generating apparatus 2 may be described in the control script so that the execution of the effect process is interrupted when the operation menu display process that is the function of the television 1 described in the first embodiment is started.

[0601] [Configuration of display data generator]

In the present embodiment, the display data generation device 2 (FIG. 46) responds to a request from the television 1. To generate display data 7 including effect processing.

[0602] In this case, the display data generation device 2 defines a control script that defines the operation (and timing) of the television 1 so that processing that should not be executed during the effect processing is executed after the effect processing. 110 is generated. For the processing with a large load that should not be executed during the effect processing, pattern data in which timing is described so as not to be executed simultaneously with the effect processing is stored in the pattern data storage unit 91 in advance. Specifically, the pattern data selection unit 61 interrupts the effect process being executed when the script described so that the character display process is executed after the effect process and the operation menu display process is started. Pattern data including the described script can be selected from the pattern data storage unit 91. The control script generation unit 80 generates a control script 110 based on the pattern data.

[0603] This makes it possible to control the television 1 so that processing with heavy loads, such as character display processing and operation menu display processing, and ethet processing are executed at different timings. As a result, the concentration of the load on the television 1 is avoided and the user can operate the television 1 smoothly.

[0604] Alternatively, a list in which processing with a large load and the start and end timings of the processing are associated with each other may be registered in the storage unit 90 in advance. When creating a control script that includes a process registered in the list, the control script generation unit 80 stores the control script in the list so that the control script is executed (interrupted) at a timing associated with the process. Create based on!

Note that the display data generation device 2 can generate a control script related to the effect processing in accordance with the contents of the received display data request message 6.

For example, as shown in FIG. 7, when the display data request message 6 including the model name and software version information is received, the related information acquisition unit 73 acquires it.

[0607] The information about the model 'software version and the function corresponding to it is stored in advance in the storage unit 90. Therefore, the display data generation device 2 (pattern data selection unit 61 / control script generation unit 80) The functions of TV 1 can be specified based on the model name and software version information. Specifically, TV 1 has a visual effect ( It is possible to determine whether or not it has a function to output effect processing) and auditory effects (sound effects, music, etc.).

[0608] The control script generator 80 only applies the effect processing when it is determined that the type of effect processing and audio output is possible when the TV 1 displays the photos of the network album as a slide show (thumbnail). And control script for voice output. Alternatively, when it is determined that the television 1 is a type that can execute effect processing and audio output, the pattern data selection unit 61 selects pattern data including a script for performing effect processing and audio output.

[0609] Conversely, if it is determined that the television 1 is a type that cannot perform audio output or effect processing, the description regarding the effect processing or audio output is not necessary, so the control script generation unit 80 Generates a control script for displaying photos in a slideshow (thumbnail) without including their descriptions.

[0610] Thus, the display data generation device 2 always generates and provides a control script in an optimum state for the requesting television 1 except for unnecessary descriptions according to the specifications of the television 1. Is possible.

[0611] <Embodiment 6>

[Modification 7—Control script change function on TV 1]

In each of the embodiments described above, in the network album system 100, the control script generation unit 80 of the server-side display data generation device 2 that provides display data generates a control script based on the pattern data described above. The case where the television 1 operates according to the control script has been described.

[0612] However, the network album system 100 of the present invention is not limited to the above configuration. The television 1 as a client that receives the display data 7 changes a part of the control script supplied from the display data generation device 2 by itself and operates according to the changed control script. It can be configured! /

[0613] Specifically, in the control script supplied from the display data generating device 2, the operation is defined so that the television 1 can change a part of the control script or replace it with another value. Contains the operation definition script 113 that you defined! [0614] The display data execution processing unit 40 of the television 1 supplies the display data generation device 2 according to the information stored in advance in accordance with the operation content definition script 113 described above. It is possible to change a part of the generated control script or replace it with another value.

[0615] At this time, the operation content definition script 113 in the control script supplied from the display data generating device 2 is replaced with information stored in the television 1 or according to the content of the information. A reference script is included to instruct the reference and retrieval of information on the client TV 1 so that it can be changed appropriately. The display data execution processing unit 40 of the television 1 acquires information on the specified device itself according to the reference script, and passes the acquired information to the layout definition script 112 as a variable value, for example. As a result, the information acquired from the device itself is embedded in the control script, and the control script to be finally executed (displayed) by the display data execution processing unit 40 is completed.

[0616] As a result, not only the display data 7 specified from the server side but also the display data 7 changed on the client side can be processed and provided to the user. The ability to provide more specialized services to individual devices and users of the devices. It becomes possible to construct a network album system 100 that can more flexibly respond to the diversifying needs of individual users.

[0617] Hereinafter, the operation of the television 1 will be described by taking as an example a case where the television 1 displays the album history screen 440a shown in (a) of Fig. 44 based on the display data 7. The television 1 changes a part of the control script received from the display data generating device 2 according to the reference script, and displays the album history screen according to the changed control script.

[0618] (Application example 1: Change the number of records displayed in the history)

As shown in FIG. 6, the television 1 stores in the album ID storage unit 53 the album IDs of the albums that the user has viewed in the past (up to three from the most recently viewed items). When the television 1 requests the display data generation device 2 for display data 7 for displaying the album history screen, the television 1 transmits the album ID stored in the album ID storage unit 53 to the display data generation device 2 ( Display data request message 6).

[0619] The display data generation device 2 receives the data request message 6 for display based on the display data request message 6. The display data 7 of the album history screen that displays the history information of the latest three albums browsed in the past in the video 1 is generated and supplied to the TV 1. In this display data 7, the layout of the album history screen, the operation of the television 1 necessary for displaying the screen, and the like are defined in the control script.

[0620] In this embodiment, the television 1 includes the operation content definition script 113 having the reference script in the received control script! /. A part of the control script is changed using data stored in the apparatus. FIG. 54 is a diagram showing a specific example of a control script including a reference script. It is defined that the reference script 160 obtains the value of the setting information “history display number” and sets it as a variable value “h_max”. TV 1 obtains information of “history display number” stored in the related information table of FIG.

[0621] Then, in the example shown in Fig. 8, TV 1 detects that the number of history displays is two, and changes the control script so that only the upper two album histories are displayed. Specifically, the visibility attribute of the album history information is changed to “hidden”.

[0622] Furthermore, the TV 1 can change the control script so that the album selection function assigned to the numeric key to select an album from the album history screen is disabled! That is, since there are two album histories displayed,

Change the control script so that only [1] and [2] are valid. That is, the television 1 changes the control script that defines the button to be pressed and the action to be executed when the button is pressed, as described in the third embodiment, based on the history display number. can do.

FIG. 55 is a diagram showing a specific example of the control script after the television 1 has changed a part of the control script received from the display data generating device 2. Before the change, the visibility attribute 161 indicated by the dashed frame indicates that the TV 1 is set according to the force setting information “History display count” (= 2) supplied to the TV 1 in the “visible” state. It has been changed to "hidden".

[0624] Then, when the display data execution processing unit 40 executes the display data 7 of the album history screen according to the control script after change, only two pieces of album history information are displayed according to the above setting information. The album history screen is output (Fig. 56). Furthermore, when the album history screen shown in Fig. 56 is displayed, the numeric key [3] is disabled. Part of the control script has been changed so that the third level is not selected.

[0625] As described above, the television 1 changes the part of the control script for displaying the album history screen according to the setting information stored in the device itself, and displays the number of display items as the display data generation device. It can be changed from the state when supplied by 2.

[0626] (Application example 2: Always display the album specified by the user)

In the present embodiment, the album ID storage unit 53 of the TV 1 includes the album ID of the album that is always displayed on the album history screen in addition to the album ID of the recently browsed album, regardless of the browse time. I can remember. Then, set the continuous display setting for the album to be valid. This setting may be stored in the related information table shown in FIG. As a result, the user can select another album that is always displayed instead of the third album, and can always display it on the album history screen, regardless of the time when it was browsed in the past.

[0627] First, the television 1 receives display data that is displayed in order from the most recently viewed content. As shown in FIG. 57, the display data 7 includes a reference script 162 for instructing to refer to the always-displayed album ID stored in the television 1. TV 1 obtains the always-displayed album ID according to the reference script 162, and changes the control script part of the current album history screen when the always-display setting is enabled. Specifically, for example, the current third album history information is replaced with the acquired constantly displayed album history information.

[0628] FIG. 58 is a diagram showing a specific example of the control script before replacement by the television 1 and the control script after replacement.

[0629] TV 1 obtains the album ID that is always displayed in accordance with the reference script 162 in FIG. 57, and then, according to the subsequent control script, the third album history information 163a is stored in the album in the album that is always displayed. Replace with history information 163b.

[0630] Since the display data execution processing unit 40 executes the anolebum history screen display process according to the replaced control script, the history information of the album for which the constant display setting is enabled in the third row is displayed. Instead, the displayed album history screen is output. [0631] As described above, the TV 1 controls the control stub tribe so that the album for which the setting is enabled is always displayed on the album history screen according to the information of the constant display setting stored in the device itself. The display content can be changed by changing (replacement) a part of.

Are defined in association with each other. That is, the control script describes a trigger when the control script execution unit 41 executes each function.

[0721] When the image display device accepts a user operation, the control script execution unit 41 is associated with the operation in the control script! / The ability to fi

As a result, the image display apparatus can execute a function defined in advance in the control script in accordance with a user operation as described in the control script.

[0723] Therefore, since the correspondence between the user operation and the function is defined in the control script, the correspondence can be easily changed. As a result, it is possible to easily assign different functions to the same user operation or to execute the same function by different user operations.

[0724] As described above, the control script is included in the display data and provided to the image display device from the outside.

[0725] Therefore, even after the image display device is put on the market, the second function to be executed by the image display device can be flexibly added and changed, and the basic function stored in the basic function program storage unit. Easily change image display device functions without updating the program It becomes possible.

[0726] Further, in the control script, the first function or the second function to be executed by the image display device when the operation is accepted is associated with the user operation. In addition, the conditions for executing the function are described for each function, and the control script execution means is configured to select a function among a plurality of functions corresponding to an operation received from the user according to the control script. The special feature is to execute functions that satisfy the above conditions.

[0727] According to the above configuration, the control script supplied to the image display apparatus is associated with a plurality of functions (first or second function) in accordance with one operation (trigger) received from the user. In addition, conditions are described for each function. The above condition is described such that the function associated with the condition is executed only when the condition is satisfied.

[0728] The control script execution unit 41 executes only a function satisfying a condition among a plurality of functions corresponding to the received operation in accordance with the control script. As a result, the image display apparatus can execute different functions depending on conditions for the same user operation.

As specific examples, it is assumed that there are a function (first function スライドショー) for displaying a plurality of photos included in an album as a slide show and a function (first function Β) for displaying thumbnails. These two functions are defined in the control script in association with one user operation (trigger). In addition, the control script is based on the number of photos in the album. If the number is 10 or less (condition Α), the first function 上記 is executed, and the number of photos is 11. In the above case (Condition B), conditions are described in association with each function so that the first function B is executed.

[0730] When the above user operation is performed, the control script execution unit 41 tries to execute the first function! /, Determines the number of photos in the album, and selects and executes the function that satisfies the condition. The power S to do.

[0731] An image data providing apparatus according to the present invention is an image data providing apparatus for generating display data for an image display apparatus to display an image, in order to achieve the above-described object, The display data defines an image, a first function that displays the image, and a second function that is an operation of the image display device when the image is displayed by the first function. A display object ID acquisition unit 71 for acquiring identification information of the requested image requested from a display data request message for requesting the display data transmitted from the image display device. A first function for displaying a request image specified by the identification information acquired by the identification information acquisition means based on the display data request message, and the image display device when the request image is displayed. A control script generating unit 80 that generates a control script that defines the second function as the operation of the control, the request image, and the control script generated by the control script generating unit 80. A display data generation unit 62 for generating display data including: and the control script generation unit 80 receives a user operation on the image display device and the operation in the control script. The first function or the second function to be executed by the image display device is defined in association with each other.

[0732] According to the above configuration, the image data providing device generates display data for displaying the requested image based on the display data request message. The display data includes a request image and a control script that defines at least a first function for displaying the request image and a second function that is an operation of the image display device during image display.

Specifically, the display target ID acquisition unit 71 acquires the identification information of the requested request image from the display data request message. This identification information identifies the requested image to be included in the display data.

Subsequently, the control script generation unit 80 generates a control script that defines the first function for displaying the request image and the second function. In addition, the following definitions are added to the control script. That is, it defines the correspondence between the first function or the second function and the user operation. The control script generation unit 80 generates a control script defining a trigger (user operation) of the first or second function according to the content of the display data request message.

Finally, the display data generation unit 62 generates display data including the request image and the control script generated by the control script generation unit 80. [0736] This defines the first and second functions according to the display data (image) requested by the image display device, and also generates a control script that defines the trigger (user operation) for each function. The display data including such a control script can be provided as a response to the request of the image display apparatus.

[0737] In addition to the first function for the image display device to display the request image, the control script generation unit 80 displays the control script when the request image is displayed by the first function. The operation of the image display device is defined and generated as the second function. The second function is also a function of the image display device realized by combining the basic functions of the image display device. Furthermore, the correspondence between each of the above functions and the user operation that triggers the function can be described in the control script.

[0738] In this way, the control script is generated according to the content of the display data and provided to the image display device, so that the display of the requested image is not limited, and various second functions can be displayed. It can be provided to the apparatus. It is also possible to specify the user operation that will be the trigger.

[0739] Therefore, even after the image display device is put on the market, the second function to be executed by the image display device can be flexibly added and changed, and the basic function program storage unit in the image display device can be changed. It is possible to easily change the function of the image display device without updating the stored basic function program.

[0740] Further, the control script generation unit 80 operates in accordance with the instruction signal transmitted from the image display device and specifying the combination of the user operation and the function of the image display device. And the first function or the second function may be associated with each other to generate the control script! /.

[0741] According to the above configuration, the control script generation unit 80 defines the correspondence between the first or second function and the trigger (user operation) according to the instruction signal transmitted from the image display device. Generate a control script. The instruction signal is included in the display data request message.

[0742] Thus, the control script in which the user operation and the function are associated with each other is supplied to the image display device as instructed by the image display device. That is, an image display device For such users, it is possible to supply a control script customized to improve operability, so that the operation of the image display apparatus can be easily customized for the user.

[0743] Alternatively, the control script generation unit 80 associates a plurality of the first function or the second function to be executed by the image display device with respect to the user's operation when the operation is received. At the same time, the control script may be generated by describing the conditions for executing the function for each function.

[0744] According to the above configuration, the control script generation unit 80 describes a plurality of functions (first or second function) in association with one operation (trigger) received by the image display device from the user. Furthermore, a control script is generated by describing conditions for each function. The above condition is described so that the function associated with the condition is executed only when the condition is satisfied! /.

[0745] Since the control script generated in this way is supplied to the image display device, the image display device only selects a function satisfying a condition among a plurality of functions corresponding to the received operation according to the control script. Execute. Thus, the image display apparatus can execute different functions depending on conditions for the same user operation.

In order to achieve the above object, an image display system of the present invention is an image display system including the above-described image display device and the above-described image data providing device, and provides the above-described image data The apparatus generates the control script based on the display data request message received from the image display apparatus, transmits display data including the request image and the control script to the image display apparatus, and The image display device is characterized in that the first function or the second function corresponding to the operation received from the user is executed according to the control script received from the image data providing device.

In order to achieve the above object, the image display system control method of the present invention processes an image data providing device and display data generated by the image data providing device to produce an image. An image display system including the image display device, wherein the image display device displays the image using the image, the first function for displaying the image, and the first function. Define the second function that is the operation of the image display device when A request step for transmitting a display data request message requesting display data including a control script to the image data providing device, and the image data providing device transmitting the display data transmitted from the image display device. An identification information acquisition step for acquiring the identification information of the requested request image from the data request message, a first function for displaying the request image specified by the identification information acquired in the identification information acquisition step, and the request The second function as the operation of the image display device when displaying an image is defined, and the user operation on the image display device is executed by the image display device when the operation is received. A control script generation step for generating a control script to be defined in association with the first function or the second function; A transmission step of generating display data including the request image and the control script generated in the control script generation step, and transmitting the data to the image display device; and the image display device provides the image data According to the control script received from the device, by executing the basic function program that is stored in the basic function program storage unit and that is called from the control script, at least V of the first function and the second function, A control script execution step for executing one of the above, and the control script execution step executes the first function or the second function corresponding to the operation received from the user according to the control script. It is characterized by being a step to

Provide as data. Further, the control script describes a correspondence relationship between a user operation accepted by the image display device and a function to be executed by the image display device when the operation is accepted. The image display device that has acquired the display data from the image data providing device receives the first operation associated with the operation when receiving a user operation based on the control script included in the display data. Or perform the second function.

[0749] This makes it possible to construct an image display system that can easily change the function of an image display device that is an embedded device. [0750] [Supplement 3]

In order to achieve the above object, an image display device according to the present invention is an image display device that processes display data for displaying an object and displays the object, wherein the display data is an object And a control script that defines at least a first function for displaying the object, and a basic function execution unit that executes a basic function program that is stored in the basic function program storage unit and that is called from the control script. 42 and the basic function execution unit 42 according to the control script to execute the first function defined by the control script, and the control script defines the second function. A control script execution unit 41 for executing the operation of the own device when the object is displayed by the function of The control script further includes a redrawing area that is a display screen area to be redrawn when the first function or the second function is a change-accompanying function accompanied by a change in the display screen. When the control script execution unit 41 executes the change-accompanying function, the control script execution unit 41 controls the basic function execution unit 42 according to the control script to identify the redrawing region, and It is characterized by executing redrawing.

[0751] According to the above configuration, the image display device acquires display data including an object and a control script that defines at least a function of displaying the object, and processes the display data. , Display the object. Specifically, a basic function execution unit 42 that executes a basic function program called from the control script is controlled by the control script execution unit 41 according to the control script, and functions (objects defined in the control script are controlled). Execute the first function to display) to display the object. That is, one or more basic functions are combined according to the control script to realize one function (such as the first function) of the image display device. An object is an object displayed on an image display device, and refers to any display object such as an image, a movie, a figure, a text, a photograph, or an illustration.

[0752] Furthermore, in addition to the first function for displaying an object, the control script includes an operation of the image display device when the object is displayed by the first function as a second function. Is defined. The second function is also combined with the basic function. This is a function of the image display device realized.

[0753] The control script execution unit 41 controls the basic function execution unit 42 according to the control script to execute the second function.

[0754] This is not limited to displaying objects using control scripts.

Various second functions can be realized on the image display device.

[0755] Furthermore, in addition to the first and second functions, a redrawing area is defined in the control script. The redrawing area is an area of the display screen to be redrawn when the image display device needs to change the display contents in accordance with the execution of the first or second function. Of the first and second functions described above, a function that involves changing the display contents is referred to as a change-accompanying function.

[0756] When the control script execution unit 41 executes the change-accompanying function, the control script execution unit 41 controls the basic function execution unit 42 according to the definition of the redrawing region described in the control script and sets the redrawing region. In particular, redrawing of the redrawing area is executed.

[0757] With this, when the first or second function is executed on the image display apparatus using the control script, the display content in the redrawing area defined by the control script can be changed.

[0758] The control script can be provided to the image display device each time it is included in the display data according to the contents to be displayed. Therefore, depending on the situation such as what kind of object is displayed or what function is executed, the redrawing area is arbitrarily defined and redrawn on the image display device. Can be made.

[0759] From the above, even after the image display device is put on the market, the second function to be executed by the image display device can be flexibly added and changed, and stored in the basic function program storage unit. Therefore, it is possible to easily change the function of the image display device without updating the basic function program. Then, it is possible to easily define the redrawing area dynamically according to the situation and cause the image display apparatus to perform redrawing.

[0760] Even when the basic function program storage unit is realized by a nonvolatile storage device such as a ROM and the stored basic function program cannot be easily rewritten, the image display is performed as described above. The function of the device can be easily changed. Therefore, built-in If the image display device of the present invention is applied to a portable device, the effect is particularly great.

[0761] In addition, since functions can be easily changed in this way, a huge amount of functions are pre-installed in advance to cover all possible functions in advance of shipment. It is possible to save waste. As a result, it is possible to reduce the burden related to the development of the image display device.

Further, the control script defining the first function and the second function is provided to the image display device by being included in the display data together with the image displayed on the image display device. Therefore, it is possible to manage the displayed image and the second function in association with each other, and even on the side that generates and transmits the display data, the side that receives and processes the display data (image Management also becomes easy in the display device.

[0763] Then, since a control script is generated for each display data (and images included in it), the image display device needs the second data necessary for the display data (object) to be processed by itself. Only the functions can be efficiently acquired according to the display data (object), or when these functions are change-accompanying functions, a suitable redrawing area is defined and a control script is acquired. It becomes possible to do.

[0764] From the above, it is possible to efficiently develop an image display device and to easily change the function of the image display device on the market.

[0765] Furthermore, the control script is defined so that the redrawing area includes the entire display area of the object or not at all! /, Or not! /, That power S is preferable.

[0766] According to the above configuration, the image display device includes the entire object or no object when specifying the redrawing area required when executing the change-accompanying function according to the control script. The redrawing area is specified as follows. In other words, only a part of the object does not have power in the redrawing area.

[0767] This makes it possible to control the image display device so that the redrawing process is executed only for the object that is entirely within the redrawing area, using the control script.

[0768] As described above, redrawing is executed by the image display device using the control script. Since the area can be arbitrarily specified, the following effects are particularly significant.

[0769] For example, it is assumed that overlapping objects are included in the display screen.

[0770] When a change-accompanying function is executed while an object (hereinafter, a change target object) is displayed, an area (for example, a circumscribed rectangle) including the entire change target object is specified as a redrawing area. However, if there are some other objects that overlap in this redrawing area, it means that you could redraw correctly by simply redrawing the object to be changed included in the redrawing area! / Ena! / It is necessary to redraw all objects included in the redrawing area! /.

[0771] Here, when the redrawing area partially includes other objects outside, for redrawing, the part of the object included in the redrawing area ( It is necessary to specify only the clipping area. In this manner, the process for obtaining the clipping region is referred to as clipping process. This clipping process becomes a process that is more burdensome for the image display device as the shape of the object becomes more complicated. Therefore, it is desirable to specify the redrawing area so that it includes the force including the entire object or not included at all. Furthermore, it is desirable to keep the redrawing area to the minimum necessary to reduce the redrawing processing load.

[0772] Here, if the above control script is used, depending on the content of the display data, the object

(Especially, an object with a complicated shape that increases the load of clipping processing) The ability to specify the redrawing area so that it does not partially contain the area and minimizes the necessary area I'll do it.

[0773] Therefore, if redrawing is performed according to such a control script, the image display apparatus specifies only the minimum necessary area as the redrawing area while avoiding clipping processing, and efficiently. It is possible to execute redrawing processing.

[0774] Alternatively, in the control script, the redrawing area is defined to be the entire display screen of the own device!

[0775] According to the configuration described above, when executing the change-accompanying function, the image display device specifies the entire display area as the redrawing area and executes the redrawing according to the control script. [0776] In this way, the entire display screen is intentionally redrawn, and the switching of the display screen is performed with the force S.

[0777] The method of specifying the redrawing area in the control script is an example, and the present invention is not limited to this. For example, in an image display device having a small working memory area, in order to smoothly switch the display screen, a redrawing area is designated so that a predetermined display area is always redrawn, or a specific object is not displayed. The image display device may be specified by specifying the outside of the object so that the image is always redrawn.

[0778] In order to achieve the above object, the image data providing apparatus of the present invention is an image data providing apparatus for generating display data for displaying an object by the image display apparatus, and displays the object. Display data generation for generating display data including the control script generation unit 80 that generates a control script that defines at least the first function, the object, and the control script generated by the control script generation unit 80 The control script generation unit 80 further defines, as a second function, an operation of the image display device when the object is displayed by the first function. When the function or the second function is a change-accompanying function accompanied by a display screen change in the image display device, the image display device redraws the image. It is characterized by generating a control script that further defines a redrawing area that is a display screen area to be drawn.

[0779] According to the above configuration, the control script generation unit 80 defines the first function and the second function, and when the above functions are functions accompanying changes, an area that needs to be redrawn. A control script defined as a redrawing area is generated.

[0780] This makes it possible to flexibly add or change the second function to be executed by the image display device even after the image display device is put on the market, and the basic function stored in the basic function program storage unit. It is possible to easily change the function of the image display device without updating the function program. Then, it is possible to easily define the redrawing area dynamically according to the situation and cause the image display device to perform redrawing.

[0781] The control script generation unit 80 controls the control script defined so that the redrawing area is either a force including the entire display area of the object or not including at all. Les, which is preferred to produce pigeons.

[0782] Thus, it is possible to control the image display device so as to execute efficient redrawing processing by specifying only the minimum necessary region as the redrawing region while avoiding heavy clipping processing. It becomes possible.

[0783] Alternatively, the control script generation unit 80 may generate a control script that is defined so that the redrawing region covers the entire display screen of the image display device.

[0784] Thus, in the image display device, the entire display screen can be intentionally redrawn, and the display screen can be switched correctly.

In order to achieve the above object, the image display system of the present invention includes the above-described image display device and the above-described image data providing device, and the above-described image data providing device is requested by the above-described image display device. Display data including the generated object and the control script is generated, and the control script execution unit 41 of the image display device operates according to the control script included in the display data. It is characterized by.

[0786] In order to achieve the above object, the image display system control method of the present invention processes an image data providing device and display data generated by the image data providing device. A display data including an object and a control script that defines at least a first function for displaying the object. A request step for requesting the image data providing device, and a first function for the image data providing device to display the object requested by the image display device. A generation step for generating a control script that defines the operation of the image display device as a second function when displaying the object! When the first function or the second function defined in the control script is a change-accompanying function accompanied by a change of the display screen in the image display device, the display screen to be redrawn by the image display device The redrawing area, which is an area, is further defined, and an additional step for adding to the control script generated in the generation step, the requested object, and the control script generated in the generation step and the addition step are A transmission step of transmitting display data to the image display device; and the image display device includes the image data providing device. In accordance with the control script received from the device, the basic function program stored in the basic function program storage unit and called from the control script is executed to execute the first function and execute the requested object. In the first function execution step, the second function execution step for executing the second function by executing the basic function program according to the control script, and the first function execution step. When the first function to be executed or the second function executed in the second function execution step is a change-accompanying function accompanied by a change of the display screen, the basic function is executed according to the control script. A specific step of controlling the function execution unit 42 to specify the redrawing area and a redrawing area specified in the specifying step are re-executed. As it characterized in that it comprises a re-drawing the scan Tetsupu demarcating! /, Ru.

[0787] According to the above method, the image display device requests the image data providing device for display data including an object and a control script that defines at least a first function for displaying the object. In response to the request, the image data providing device generates display data including the requested object. The image data providing apparatus creates a control script to be included in the display data as follows.

That is, first, a first function for displaying a requested object is defined, and an operation of the image display device when the object is displayed by the first function is defined as a second function. Generate a control script defined as Next, when the first function or the second function is a change-accompanying function accompanied by a change of the display screen in the image display device, the display screen to be redrawn by the image display device A redrawing area, which is an area, is further defined and included in the control script.

[0789] The image display device receives display data including the control script generated as described above from the image data providing device, and the control script execution unit 41 operates based on the control script. I do. Specifically, the first function and the second function are executed according to the control script, and when each function is a change-accompanying function, the redrawing area is specified and the redrawing is executed. .

[0790] This allows the image display device to execute various second functions as well as the first function of displaying an object using the control script, and the first or second function. It is possible to realize an image display system that can specify an area to be redrawn when the function is executed to the image display device.

[0791] From the above, even after the image display device is put on the market, the second function to be executed by the image display device can be flexibly added and changed and stored in the basic function program storage unit. Therefore, it is possible to easily change the function of the image display device without updating the basic function program. Then, it is possible to easily define the redrawing area dynamically according to the situation and cause the image display apparatus to perform redrawing.

[0792] [Supplementary Item 4]

In order to achieve the above object, an image display device according to the present invention is an image display device that processes display data acquired from the outside to display an image, and the display data includes an image and an image display device. A first function for displaying the image, and a control script for defining the second function, which is the operation of the device when displaying the image by the first function! / The basic function execution unit 42 that executes the basic function program that is stored in the basic function program storage unit and that is called from the control script, and the basic function execution unit 42 that controls the control script according to the control script. A control script execution unit 41 for executing the first function and the second function defined in the script, and the control script includes an image displayed by the first function with a motion. The visual effect output function to be displayed is defined at least as the second function, and the control script execution unit 41 displays the image according to the control script and visually displays the image. It is characterized by executing an effect output function.

[0793] According to the above configuration, the image display device acquires display data including an image and a control script that defines at least the first function for displaying the image, and processes the display data. The above image is displayed. Specifically, the basic function execution unit 42 that executes the basic function program that is also called the control script force included in the display data is controlled by the control script execution unit 41 according to the control script, and is defined in the control script. Yes The first function is executed and the image is displayed. That is, one or more of the above basic functions are combined according to the control script to realize one function (such as the first function) of the image display device. [0794] Further, in addition to the first function for displaying an image, the control script includes the second function indicating the operation of the image display device when the object is displayed by the first function. Is defined as The second function is also a function of the image display device realized by combining the basic functions.

[0795] The control script execution unit 41 controls the basic function execution unit 42 according to the control script to execute the second function.

[0796] Accordingly, it is possible to realize not only the function of displaying an image using a control script but also various second functions in the image display apparatus.

[0797] Specifically, as the second function, a visual effect output function for displaying an image displayed by the first function with movement is defined in the control script.

Therefore, the control script execution unit 41 displays the image by the first function and executes the visual effect output function for the image. That is, the image is displayed with a motion.

[0799] As described above, by using the control script, the visual effect output function can be provided to the image display device every time it is included in the display data in accordance with the contents to be displayed. Therefore, it is possible to cause the image display device to execute the visual effect output function depending on what kind of image is displayed. The second function, the visual effect output function, can provide more interesting content to the user in accordance with the displayed content.

[0800] From the above, even after the image display device is put on the market, the second function to be executed by the image display device can be flexibly added and changed and stored in the basic function program storage unit. Therefore, it is possible to easily change the function of the image display device without updating the basic function program.

[0801] Even if the basic function program storage unit is realized by a non-volatile storage device such as a ROM and the stored basic function program cannot be easily rewritten, the image display is performed as described above. The function of the device can be easily changed. Therefore, if the image display device of the present invention is applied to an embedded device, the effect is particularly great.

[0802] In addition, since functions can be easily changed in this way, there is a huge amount of functions to be incorporated in advance in order to cover every need before shipment. It is possible to eliminate the waste of having the function in advance. As a result, it is possible to reduce the burden related to the development of the image display device.

[0803] Furthermore, the control script defining the first function and the second function is provided to the image display device by being included in the display data together with the image displayed on the image display device. Therefore, it is possible to manage the displayed image and the second function in association with each other, and even on the side that generates and transmits the display data, the side that receives and processes the display data (image Management also becomes easy in the display device.

[0804] Then, since a control script is generated for each display data (and the image included in it), the image display device has a second function necessary for the display data (image) to be processed by itself. The ability to efficiently acquire only the (visual effect output function) according to the display data (image) is S Kurakura.

[0805] From the above, it is possible to efficiently develop an image display device and to easily change the function of the image display device on the market.

[0806] In the control script, an object display function for displaying an object superimposed on an image displayed by the first function is defined as the second function, and the object is displayed on the own device. The timing of each of the second functions is defined so that the display function is not executed during the execution of the visual effect output function, and the control script execution unit 41 defines the timing defined by the control script. Accordingly, it is preferable to execute each of the second functions.

[0807] The control script may further define an object display function as the second function. The object display function is a function for displaying an object superimposed on an image displayed by the first function. An object is an object displayed on an image display device, and refers to any display object such as an image, video, graphic, text, photo, or illustration!

[0808] Then, the control script execution unit 41 executes the visual effect output function and the object display function for the image displayed by the first function according to the control script. Here, the timing of each function is defined in the control script so that the object display function is not executed during the execution of the visual effect output function. Therefore, the control script execution unit 41 executes each function so that the visual effect output function and the object display function are not executed simultaneously.

[0809] When the visual effect output function and the object display function are executed at the same time, the image display device must display the object superimposed on the image to be displayed with movement. In this way, the process of drawing another character or graphic on the image with animation added is a process with a heavy load. Therefore, the load concentrates on the image display device, and there is a problem that each function cannot be executed smoothly.

[0810] According to the above configuration, the control script execution unit 41 executes each function according to the control script so that the visual effect output function and the object display function are not executed simultaneously. It is possible to avoid the concentration of load on the device.

[0811] Specific examples of the object display function include a text display function (a function that displays comments and titles of photographs (images)), or an operation menu display function (a list of operations that can be performed on the photograph by the user). Table display function).

[0812] In the control script, the start of the object display function is defined as an end condition of the visual effect output function. When the control script execution unit 41 starts executing the object display function, In addition, the execution of the visual effect output function may be terminated according to the termination condition.

[0813] According to the above configuration, when the control script execution unit 41 interrupts a start command for the object display function while executing the visual effect output function (for example, by the user operation, the object display function The execution of the visual effect output function is terminated according to the above termination condition.

[0814] Thus, since the object display function can be executed after the visual effect output function is completed (suspended), it is possible to avoid the load from being concentrated on the image display device.

[0815] Alternatively, in the control script, the end of the visual effect output function is defined as a start condition of the object display function, and the control script execution unit 41 executes the visual effect output function. When finished, follow the start conditions above Execution of the object display function may be started.

[0816] According to the above configuration, the control script execution unit 41, when executing the visual effect output function, interrupts the start command of the object display function, or the visual effect output function and the object display function. When execution is executed at the same time (or almost simultaneously), the visual effect output function is first executed according to the start condition, and then the object display function is started.

[0817] Thus, the object display function is executed after the execution of the visual effect output function is completed, and thus it is possible to avoid the concentration of the load on the image display device.

[0818] The control script further defines an auditory effect output function for outputting audio data associated with the image displayed by the first function as the second function. The script execution unit 41 may execute at least one of the visual effect output function and the auditory effect output function corresponding to the image displayed by the first function according to the control script.

[0819] Thus, the image display device can display an image by the first function and the visual effect output function, and can output audio data associated with the image, thereby providing more enriched content to the user. It becomes possible to do.

[0820] In order to achieve the above object, the image data providing apparatus of the present invention is an image data providing apparatus for generating display data for displaying an image by the image display apparatus. Is a control script that defines an image, a first function that displays the image, and a second function that is an operation of the image display device when the image is displayed by the first function. A display target ID acquisition unit 71 for acquiring identification information of the requested image requested from a display data request message for requesting the display data transmitted from the image display device, and the display The first function for displaying the requested image specified by the identification information acquired by the target ID acquisition unit 71 is defined, and the visual effect output function for displaying the requested image with movement is at least a second function. Define A control script generation unit 80 for generating a control script, and a display data generation unit 62 for generating display data including the request image and the control script generated by the control script generation unit 80. It is characterized by that! /! [0821] According to the above configuration, the image data providing device displays the requested image that is the requested image based on the display data request message that requests the display data generated by the image display device. Generate display data for. The display data includes a request image, a first function that displays the request image, and a control script that defines the second function corresponding to the request image. Here, as the second function, at least a visual effect output function for displaying the request image by adding a motion when the request image is displayed is defined.

[0822] Specifically, the display target ID acquisition unit 71 acquires the identification information of the requested image from the display data request message. This identification information identifies the requested image to be included in the display data.

[0823] Subsequently, the control script generation unit 80 generates a control script that defines a first function for displaying the request image. In addition, the following definitions are added to the control script. That is, this is the definition of the operation as the second function of the image display device when the requested image is displayed by the first function. The control script generation unit 80 generates a control script defining the second function (at least the visual effect output function) according to the content of the display data request message.

[0824] Finally, the display data generation unit 62 generates display data including the request image and the control script generated by the control script generation unit 80.

[0825] Thus, according to the display data (image) requested by the image display device, the first and first

A control script that defines the two functions can be generated, and display data including such a control script can be provided as a response to a request from the image display device.

[0826] In addition to the first function for the image display device to display the request image, the control script generation unit 80 displays the control script when the request image is displayed by the first function. The operation of the image display device is defined and generated as the second function. The second function is also a function of the image display device realized by combining the basic functions of the image display device.

[0827] Thus, the control script is generated according to the content of the display data, and the image display device By providing the image display device, it is possible to provide not only the function of displaying the requested image but also various second functions to the image display device. Since the visual effect output function is defined as at least the second function, the image display device displays the image displayed by the first function with a motion added. This visual effect output function makes it possible to provide more interesting content for the user in accordance with the display content.

[0828] As described above, the second function to be executed by the image display device can be flexibly added and changed even after the image display device is put on the market, and the basic function program is stored in the image display device. It is possible to easily change the function of the image display device without updating the basic function program stored in the unit.

[0829] The above-mentioned basic function program storage unit of the image display device is realized by a non-volatile storage device such as a ROM, and even when the stored basic function program cannot be easily rewritten, as described above. In addition, the function of the image display device can be easily changed. Therefore, if the control script generated by the control script generation unit 80 is provided to an embedded device having the basic function execution unit 42 of the image display device described above, the effect is particularly great.

[0830] In addition, since the functions of the image display device can be easily changed in this way, the functions to be incorporated into the image display device are assumed by assuming all needs before shipping. It is possible to eliminate the waste of installing a huge amount of functions in advance in order to cover all of the above. As a result, it becomes possible to reduce the burden on the development of the image display device.

[0831] Further, the control script defining the first function and the second function is provided to the image display device by being included in the display data together with the image displayed on the image display device. Therefore, the displayed image and the second function can be managed in association with each other, and the display data is also received on the side that generates and transmits the display data (image data providing apparatus). Management on the processing side (image display device) is easy.

[0832] Since the control script generation unit 80 generates a control script for each display data (and images included therein), the display data (images) processed by the image display device is displayed. The second function required for the image) can be efficiently provided to the image display device according to the display data (image).

[0833] From the above, it is possible to efficiently develop an image display device and easily change the function of the image display device on the market.

[0834] The visual effect applicable to the image provided to the image display device is stored in the effect information storage unit in association with the image, and the control script generation unit 80 is associated with the requested image. A visual script that defines a visual effect output function for outputting the visual effect may be generated by identifying the visual effect that is present from the effect information storage unit.

[0835] According to the above configuration, the control script generation unit 80 identifies the visual effect applicable to the requested image requested by the display data request message from the effect information storage unit. Then, a visual effect output function for executing the visual effect on the requested image is defined in the control script.

[0836] This makes it possible to generate and provide a control script so that the image display apparatus can execute a visual effect suitable for the image requested of the image display apparatus.

[0837] The display data request message includes specification information indicating the basic functions of the image display device. The control script generation unit 80 outputs the visual effect according to the specification information. It is preferable to determine whether or not to include the function definition in the control script.

[0838] According to the above configuration, the display data request message transmitted from the image display device includes specification information indicating what basic function the image display device has! /. ing. Based on the specification information, the control script generation unit 80 determines whether or not the image display device has a basic function for executing the visual effect output function. Then, according to the determination, it is determined whether or not to include the visual effect output function in the control script provided to the image display device.

[0839] This makes it possible to provide a more appropriate control script according to the basic functions of the image display device.

[0840] Specifically, when the control script generation unit 80 determines that the image display device is a model capable of executing the visual effect output function, the control script generation unit 80 provides the control provided to the image display device. You can decide to include the definition of the visual effect output function in your script. On the other hand, when it is determined that the image display apparatus is a model that cannot execute the visual effect output function, it can be determined not to include the definition of the visual effect output function.

[0841] Originally having a basic function for executing the second function! /, N! /, Even if the second function is defined for the image display device, it is useless. Therefore, in such a case, by not including the definition of the second function in the control script, the data volume of the control script can be reduced, and the load of transmission / reception processing, control script analysis processing, etc. Can be reduced.

[0842] The control script generation unit 80 further defines an object display function for displaying an object superimposed on the image displayed by the first function as a second function, and the image display device includes the above-described object display function. A control script that defines the timing of each of the second functions may be generated so that the object display function is not executed during the execution of the visual effect output function.

[0843] According to the above configuration, when the control script generation unit 80 defines, as the second function, the object display function that displays an object superimposed on the image displayed by the first function. The control script is generated by defining the timing of each function so that the object display function and the visual effect output function are not executed simultaneously.

[0844] Thus, in the image display device, the object display function and the visual effect output function can be prevented from being executed simultaneously.

[0845] When the visual effect output function and the object display function are executed at the same time, the image display device must display the object superimposed on the image to be displayed with movement. In this way, the process of drawing another character or graphic on the image with animation added is a process with a heavy load. Therefore, the load concentrates on the image display device, and there is a problem that each function cannot be executed smoothly.

[0846] According to the above control script, the visual effect output function and the object display function are not executed at the same time on the image display device, so that it is possible to avoid the concentration of the load on the image display device. Force S Kanakura.

[0847] A specific example of the timing of each of the second functions is as follows. [0848] In the image data providing apparatus, the control script generation means may generate a control script that defines the start of the object display function as an end condition of the visual effect output function.

[0849] Alternatively, the control script generation means may generate a control script that defines the end of the visual effect output function as a start condition of the object display function.

[0850] In order to achieve the above object, the image display system of the present invention includes the above-described image display device and the above-described image data providing device, and the control script execution unit 41 of the image display device includes: According to the control script included in the display data provided from the image data providing device, the visual effect output function corresponding to the requested image is actually executed.

[0851] In order to achieve the above object, the image display system control method of the present invention processes an image data providing device and display data generated by the image data providing device to produce an image. The image display system includes a first display function, and the first function for displaying the image and the first function for displaying the image. A requesting step for requesting the image data providing apparatus for display data including a control script defining a second function, which is an operation of the own apparatus when the image data is provided. Generates a control script that defines a first function for displaying a requested image requested by the image display device and a visual effect output function for displaying the requested image with movement as a second function. Step A transmission step for transmitting display data to the image display device, and the image display device receives from the image data providing device. In accordance with the control script, the basic function program stored in the basic function program storage unit and called from the control script is executed to execute the first function and display the request image. A function execution step and a second function execution step of executing the visual effect output function corresponding to the image as a second function by executing the basic function program according to the control script. As a feature!

[0852] According to the above method, the image display device has an image and a first function for displaying the image. And display data including the control script that defines the second function, which is the operation of the image display device when displaying the image, and requests the image data providing device, and in response to the request, the image data The providing device generates display data including the requested image. The image data providing device creates a control script to be included in the display data as follows.

That is, first, the first function for displaying the requested image is defined, and the operation of the image display device when the image is displayed by the first function is changed to the second function. Generate a control script defined as Here, as the second function, at least a visual effect output function for displaying the image with movement is defined.

[0854] The image display device receives display data including the control script generated as described above from the image data providing device, and the control script execution unit 41 operates based on the control script. I do. Specifically, the first function and the second function (at least the visual effect output function) are executed according to the control script. As a result, the image S displayed with the first function can be displayed with the power S to add the associated visual effect.

[0855] This allows the image display device to execute various second functions as well as the first function of displaying an image using a control script, and the second function is a visual effect output function. In such a case, an image display system capable of displaying the image with a motion can be realized in the image display device.

[0856] From the above, even after the image display device is put on the market, the second function to be executed by the image display device can be flexibly added and changed and stored in the basic function program storage unit. Therefore, it is possible to easily change the function of the image display device without updating the basic function program. Since an image can be displayed with a visual effect corresponding to the image to be displayed, it is possible to provide more interesting content to the user.
