Description

  The present invention relates to a display device that displays a display image based on content data, a display device control method, a display device control program, and a recording medium on which the display device control program is recorded.

  In recent years, various services have been provided for mobile terminals such as mobile phones. With the spread of this service, mobile terminals have increased the opportunity to download content including image data or text data as display data. By the way, when content is downloaded and viewed on the display screen of a mobile terminal, the display screen range is smaller than the display range of the content, and there are cases where the entire content cannot be displayed at once.

  In such a case, the user of the mobile terminal usually operates the operation unit included in the mobile terminal, and moves the display content up and down, left and right so as to display a portion that cannot be displayed on the screen. Perform scrolling.

By the way, when such scrolling is executed, it is preferable that the display content is set so that it can be moved by an appropriate amount of movement. For example, Patent Document 1 discloses a display device in which an operator can select and set a scroll amount at the time of scrolling in advance. Patent Document 2 discloses a display device that can calculate the number of scrolls and the scroll interval based on display data. Patent Document 3 discloses a scroll control device that determines a scroll amount for displaying an item according to the number of past selections for the item to be selected.
JP 2002-312094 A (published on October 25, 2002) JP 2005-156626 A (released on June 16, 2005) JP 2006-11690 A (published January 12, 2006)

(Hardware configuration of communication terminal)
Next, details of the hardware configuration of the communication terminal 1 having the above-described rotation mechanism will be described with reference to FIG. FIG. 3 shows an embodiment of the present invention, and is a block diagram showing a main configuration of the communication terminal 1.

  As shown in FIG. 3, the communication terminal 1 according to the present embodiment is wireless in addition to the hinge unit 4, the communication antenna 5, the operation unit 6, the microphone 7, the speaker 8, and the display area 9. The communication processing unit 11, signal processing unit 12, display driver (cursor display means) 13, content storage device 14, and main control unit 16 are provided.

  Here, the content storage device 14 is a readable / writable storage device that stores the content 15 acquired from the outside or the content 15 registered in advance in the initial state, and can be realized by, for example, a flash memory, a hard disk, or the like. .

  The main control unit 16 controls each unit included in the communication terminal 1 and can be realized by, for example, a CPU. Here, when the main control unit 16 is realized by a CPU or the like, for example, the CPU reads the system program stored in the ROM or the like (not shown) into the RAM or the like (not shown) to execute the communication. Each unit of the terminal 1 can be controlled.

  And in the communication terminal 1 comprised in this way, a telephone call function, a content display function, etc. can be performed as follows.

  First, in the communication terminal 1, under the transmission / reception control by the wireless communication processing unit 11, a signal is transmitted / received to / from a base station (not shown) via the communication antenna 5, and the signal transmitted from the signal processing unit 12 Is subjected to predetermined signal processing. As a result, the communication terminal 1 outputs the sound transmitted from the partner apparatus via the base station from the speaker 8 or transmits the sound input from the microphone 7 to the partner apparatus via the base station. In other words, a so-called call function is realized.

  In addition, the communication terminal 1 can transmit / receive a signal to / from a base station via the communication antenna 5 and receive content 15 from a server or the like connected to be communicable with the base station (content acquisition). function). The communication terminal 1 receives the content 15 via the base station via the communication antenna 5 under the transmission / reception control by the wireless communication processing unit 11. The received content 15 is stored in the content storage device 14 under the control of the main control unit 16.

  Furthermore, in the communication terminal 1, the main control unit 16 reads the content 15 from the content storage device 14 in response to an instruction from the user input from the operation unit 6, and controls the display driver 13 to display it in the display area 9. (Content display function).

  Further, in a state where an image based on the content 15 is displayed in the display area 9, the pointer displayed on the display screen is moved according to an instruction from the operation unit 6, and the display content is shifted left and right or up and down according to the movement. So-called scrolling can be performed. Thereby, even when the display range (display image range) of the image displayed based on the content 15 is larger than the display range 9 (display range in the display region 9), the communication terminal 1 does not yet display the display range. The display part can be displayed (scroll display processing function).

  The details of the scroll display process in the display area 9 will be described later.

  Further, the function of the communication terminal 1 is not limited to the above-described call function, content display function, and scroll display processing function, and includes a digital TV reception antenna and a tuner and realizes a TV reception function. It may be. Furthermore, it may further include an imaging unit configured by a charge coupled device (CCD) or a CMOS to realize a camera function for taking an image.

(Scroll display processing)
Next, the software configuration of the communication terminal 1 that executes scroll display processing will be described with reference to FIG.

  First, the communication terminal 1 according to the present embodiment is configured to be able to scroll the display content of the content 15 in accordance with an operation instruction input from the operation unit 6 as shown in FIG. More specifically, the display content can be moved in conjunction with the operation of the electrostatic pad 64 in the operation unit 6 as follows.

  That is, the user of the communication terminal 1 presses the finger against the electrostatic pad 64 while the pointer is displayed at the end of the display area 9 (the position in contact with the left side surface of the display area 9 in FIG. 4). Assume that the finger is moved once in the x-axis direction from the right side to the left side in FIG. In response to this operation, the display content (“A”) in the display area 9 moves in the x-axis direction from the left side to the right side in FIG.

  The x axis is the horizontal axis in the rectangular display area 9, and the y axis direction corresponds to the vertical axis in the rectangular display area 9. FIG. 4 shows an embodiment of the present invention and is a diagram for explaining an example of scroll display processing.

  By the way, in the communication terminal 1 which concerns on this Embodiment, with respect to predetermined | prescribed contact time with one operation of the user in this electrostatic pad 64, more precisely the finger | toe electrostatic pad 64 moved to ax or y-axis direction The scroll amount of the display content is defined for each content 15.

  More specifically, as shown in FIG. 5, a value (pixel value) that defines how much display content is moved in the x-axis direction and the y-axis direction in response to one operation by the user in the content 15. Is described in the XML format. For example, in the example of FIG. 5, as the scroll amount for one operation of the user, the display content is moved by 10 pixels in the case of an operation in the x-axis direction and 15 pixels in the case of an operation in the y-axis direction. Information is included in the content 15. FIG. 5 is a diagram showing an example of the scroll amount described in the content 15 used by the communication terminal 1 according to the present embodiment.

  The scroll amount is set by the creator of the content 15 when the content 15 is created, for example. For this reason, the content creator can set the content 15 to be displayed in a desired display mode.

  That is, as shown in FIG. 6, when the scroll amount to be set is changed, the state of the display content after the movement differs depending on whether the scroll amount is large or small. For this reason, the viewer who views the content 15 has a very different impression from the display content. Therefore, how much the display content of the content 15 is moved in response to one operation from the user is an important element for the creator of the content 15.

  FIG. 6 shows an example of display before and after scrolling the display content displayed on the display unit 3 of the communication terminal 1 according to the present embodiment. Each display example with the case where it becomes larger than the movement is shown.

  Next, the software configuration of the communication terminal 1 that reads out the scroll amount from the content 15 in which the scroll amount is embedded as described above and executes the scroll display process will be described below with reference to FIG.

(Software configuration 1 of communication terminal regarding scroll display processing)
FIG. 1 shows an embodiment of the present invention and is a block diagram showing a software configuration of a communication terminal 1 related to scroll display processing. As shown in FIG. 1, the communication terminal 1 includes an operation instruction receiving unit 21, a pointer display management unit (cursor display means) 22, and a scroll amount determination unit 23 as functional blocks. The pointer display management unit 22 and the display driver 13 implement the cursor display means of the present invention.

  The operation instruction receiving unit 21 receives an operation instruction by the user input from the electrostatic pad 64 and grasps the contents of the operation instruction. For example, when the user moves a finger pressed from the top to the bottom in the y-axis direction from the electrostatic pad 64, the operation instruction receiving unit 21 detects the movement. And the information regarding the moving direction of the pointer according to the movement is grasped. For example, in the above-described example, the information related to the movement direction is information that the display position of the pointer is moved from the top to the bottom in the y-axis direction in the display area 9.

  When the operation instruction receiving unit 21 grasps information related to the movement state of the pointer, the operation instruction receiving unit 21 notifies the pointer display management unit 22 of the operation instruction content from the user.

  The pointer display management unit 22 also manages where the pointer is located in the display area 9 of the display unit 3 and the display position of the pointer. When the pointer display management unit 22 receives a notification of information related to the movement of the pointer from the operation instruction receiving unit 21, the pointer display management unit 22 moves the display position of the pointer in the direction indicated by this information. In addition, when the input from the user is continuously received from the electrostatic pad 64, the display position of the pointer according to the input is moved. The movement of the display position of the pointer is executed until the end of the display area 9 is reached as long as the input from the user continues. Further, the amount of movement of the display position of the pointer that moves according to the input from the user is determined in advance by initial setting.

  When the pointer display position moves to the end of the display area 9, the pointer display management unit 22 determines to start scrolling the display content displayed in the display area 9. When the operation input from the user is further received in a state where the display position of the pointer is positioned at the end of the display area 9, the pointer display management unit 22 displays the display on the scroll amount determination unit (scroll amount determination unit) 23. Instructs to determine the scroll amount for the content. When the pointer display management unit 22 transmits this instruction, the pointer display management unit 22 also notifies information regarding the moving direction of the pointer.

  The scroll amount determination unit 23 determines the scroll amount when scrolling the display content based on the content 15. When receiving an instruction to determine the scroll amount from the pointer display management unit 22, the scroll amount determination unit 23 reads the content 15 and acquires information on the scroll amount included in the content 15.

  The information about the scroll amount acquired here is the amount (pixel value) by which the display content is moved in response to one operation by the user as described above. Therefore, the scroll amount determination unit 23 instructs the display driver 13 to move and display the display content of the content 15 by the acquired scroll amount, and causes the display unit 3 to display the content.

(Processing flow 1 of scroll display processing)
Next, a processing flow of “scroll display processing” in the communication terminal 1 having the above-described software configuration will be described below with reference to FIG. FIG. 7 shows an embodiment of the present invention and is a flowchart showing a processing flow of scroll display processing by the communication terminal 1.

  First, it is assumed that the communication terminal 1 holds the content 15 in the content storage device 14 and performs display based on the content 15 as a premise.

  Under such a premise, in the communication terminal 1, it is assumed that the operation instruction receiving unit 21 receives an operation instruction input from the electrostatic pad 64 by a user who desires to move the display content (step S11 and thereafter). S11).

  In response to the operation instruction from the user, the pointer display management unit 22 moves the display position of the pointer in the display area 9 in the direction desired by the user, and instructs the display driver 13 to display the pointer. Instruct. By this instruction, the pointer moves in the direction desired by the user in the display area 9 (S12).

  Here, the input of the operation instruction from the user is continued, and the display position of the pointer in the display area 9 reaches the end in the direction in which the display content desired to be displayed by the user exists. Further, when an operation instruction from the user is further received (“YES” in S13), the pointer display management unit 22 determines the scroll amount set in the content 15 with respect to the scroll amount determination unit 23. The scroll amount determination unit 23 is instructed. In response to this instruction, the scroll amount determination unit 23 analyzes the displayed content 15 and determines the scroll amount for each user operation set in the content 15 (S14).

  The scroll amount determination unit 23 moves and displays the display content of the content 15 by the determined scroll amount (S15). That is, the scroll amount determination unit 23 instructs the display driver 13 to move and display the display content of the content 15 by the determined scroll amount, and outputs the image data of the portion to be displayed of the content 15.

  As described above, the communication terminal 1 according to the present embodiment allows the display content of the content 15 to be displayed within the display image range of the content 15 while the input of the operation instruction from the user continues (during “YES” in S16). Move.

  Note that when the operation instruction from the user is not received or the display content cannot be moved any more, the communication terminal 1 stops the movement of the display content of the content 15 (end).

  Thus, in communication terminal 1 according to the present embodiment, per operation according to the user's operation on electrostatic pad 64, that is, the contact time of the user's finger moving on electrostatic pad 64. The display contents can be moved so that the scroll amount is reached.

  In the “scroll display process” described above, scrolling is executed with the scroll amount described in the content 15. The scroll amount is constant over the entire display image range of the content 15.

  However, the scroll amount is not necessarily limited to a configuration in which the entire display image range of the content 15 is constant, and may be configured such that the scroll amount is set for each predetermined position in the display image range.

  A scroll process performed by the communication terminal 1 when the scroll amount is defined for each predetermined position in the display image range in the content 15 will be described with reference to FIGS.

  First, a description example of the scroll amount when the scroll amount is defined for each predetermined range in the display image range will be described with reference to FIG. FIG. 8 is a diagram showing a description example of the scroll amount when the scroll amount is defined for each predetermined range in the display image range in the content 15.

  In the content 15, when the scroll amount is defined for each predetermined position in the display image range, the scroll amount described in the content 15 is described as shown in FIG. That is, first, position coordinates are set in the display image range of the content 15, and an area for setting the scroll amount is defined by the position coordinates.

  More specifically, as shown in FIG. 8, <x-start value = "0"> </ x-start> and <x-start value = "120"> </ x-end> A range between 0 and 120 is shown in the x-axis direction. Furthermore, by <y-start value = "0"> </ y-start> and <y-start value = "120"> </ y-end>, a value between 0 and 120 in the y-axis direction is set. Indicates the range.

  Therefore, by these descriptions, it is possible to specify an area defined by four points of coordinates (0,0), (0,120), (120,0), and (120,120) in the display image range.

  Further, when scrolling in the x-axis direction in the region defined by the description <x-scroll value = "10"> </ x-scroll>, the scroll amount is 10 pixels per user operation. It is set as follows.

  Thus, in the content 15 according to the present embodiment, position coordinates can be set in the display image range, and the scroll amount in the specified range can be set using the coordinates.

(Software configuration 2 of communication terminal for scroll display processing)
Next, the software configuration of the communication terminal 1 that reads out the scroll amount from the content 15 in which the scroll amount is described as described above and executes the scroll process is referred to as “software configuration 2 of the communication terminal related to scroll display processing” as shown in FIG. Will be described with reference to FIG. FIG. 9 is a diagram illustrating a software configuration of the communication terminal 1 regarding scroll processing when different scroll amounts are defined for each predetermined position in the display image range.

  As shown in FIG. 9, the communication terminal 1 is configured to further include a content position monitoring unit (specifying means) 24 in the software configuration 1 shown in FIG. 1. The communication terminal 1 further includes a display range storage device 17 that stores the display range position information 18 as a storage device. In addition, the same code | symbol is attached | subjected to the same member as each part with which the software structure shown in FIG. 1 is provided, and the description is abbreviate | omitted.

  The display range storage device 17 is a readable / writable storage device that stores the display range position information 18, and can be realized by, for example, a flash memory, a hard disk, or the like. The display range position information 18 stored in the display range storage device 17 is information recorded by a content position monitoring unit 24 described later, and is history information of the display range position in the display image range of the content 15 in the display area 9. is there. Details regarding the display range position information 18 will be described later.

  The content position monitoring unit 24 displays the display image of the display area 9 based on the operation instruction for instructing the movement of the display content received from the user via the pointer display management unit 22 and the display range position information 18. The display range position in the range is specified. The content position monitoring unit 24 also records the specified result in the display range position information 18. More specifically, the content position monitoring unit 24 can specify and manage the display range position of the display area 9 in the display image range as follows.

  That is, as shown in FIG. 10, a predetermined position in the display area 9 is set as a reference point. Then, the content position monitoring unit 24 grasps how much the reference point has been moved by scrolling, and specifies the position of the display area 9 on the coordinates set in the display image range of the content 15. FIG. 10 is a diagram illustrating an example of a movement state in the x-axis direction of the display range of the display area 9 in the display image range of the content 15.

  For example, in the content 15, the scroll amount for each operation of the user is set to 10 pixels in the range from 0 to 120 pixels in the x-axis direction, and the scroll amount is set to 20 pixels in the range from 120 pixels to 240 pixels. It shall be.

  The reference point in the display range at the initial position of the display area 9 is assumed to be located at 0 pixel.

  Under such a premise, when an operation instruction is continuously received from the user so as to move the display range from the left side to the right side of the x-axis in FIG. 10, the reference point set in the display area 9 for each operation is Each pixel moves from the initial position to the right side of the x axis. When the reference point moves beyond 120 pixels, the scroll amount defining the movement is changed to 20 pixels.

  That is, the content position monitoring unit 24 grasps the number of operation instructions input from the user and the moving direction and scroll amount of the display range instructed by the operation, so that the display range can be changed from the initial position. It is possible to specify where the display area 9 has moved, that is, the position of the display range of the display area 9 in the display image range. Each time the scroll amount determination unit 23 determines the scroll amount, the content position monitoring unit 24 is configured to output information about the determined scroll amount to the content position monitoring unit 24. You can figure out the quantity.

  More specifically, as shown in FIG. 12, the content position monitoring unit 24 determines the display range position of the display area 9 before scrolling, that is, the position coordinates of the reference point, and the scroll amount as the display range position information 18. The position coordinates of the reference point when moving by the scroll amount determined by the unit 23 are recorded. By referring to the display range position information 18, the content position monitoring unit 24 can grasp the position of the display range in the display image range of the display area 9 when an operation instruction from the user is received. it can. FIG. 12 shows an example of the display range position information 18 recorded by the communication terminal 1 according to the present embodiment.

  When the content position monitoring unit 24 specifies the position of the display range of the display area 9 in the display image range of the content 15 in this way, the scroll amount determination unit 23 is notified of information regarding the position of the specified display range.

  Based on the notification received from the content position monitoring unit 24, the scroll amount determination unit 23 determines a scroll amount for moving the display contents in accordance with an operation instruction input from the user. Then, the display driver 13 is instructed to move and display the display content with the determined scroll amount, and information on the determined scroll amount is notified to the content position monitoring unit 24.

(Processing flow 2 of scroll display processing)
Next, a processing flow of “scroll display processing” in the communication terminal 1 having the above-described software configuration 2 will be described below with reference to FIG. FIG. 11 shows another embodiment of the present invention, and is a flowchart showing an example of a processing flow of scroll display processing by the communication terminal 1.

  First, the preconditions and the process up to the state where the operation instruction is received from the user and the display position of the pointer is positioned at the end of the display area 9, that is, the processes from step S21 to S23 are steps of the process flow shown in FIG. Since it is the same as the process from S11 to S13, its description is omitted.

  That is, when the display position of the pointer in the display area 9 reaches the end in the direction in which the user wants to display the display content and further receives an operation instruction from the user (“YES” in S23), the pointer display is performed. The management unit 22 instructs the content position monitoring unit 24 to specify the position of the display range of the display area 9 in the display image range of the content 15.

  In response to the instruction from the pointer display management unit 22, the content position monitoring unit 24 specifies the position of the display range in the display area 9 in the display image range (S24). In the state where the display position of the pointer in the display area 9 has reached the end of the display area 9 and when an operation instruction from the user is further received, the content position monitoring unit 24 displays the display range of the content 15 in the content area 15. The initial position in the display image range is specified. Then, the content position monitoring unit 24 notifies the scroll amount determination unit 23 of the specified result together with the direction of the display content instructed by the user's operation instruction.

  When receiving the notification from the content position monitoring unit 24, the scroll amount determination unit 23 determines the scroll amount according to the position of the display range of the display area 9 specified by the content position monitoring unit 24 (S25). For example, the direction indicated by the operation instruction from the user is the direction from the left to the right on the x axis in the display area 9, and in the area to which the display range of the display area 9 belongs, the direction along the x axis is 10 pixels. If it is set to scroll one by one, the scroll amount is determined to be 10 pixels. Then, the display driver 13 is instructed to display so that the display content moves along the x-axis with the determined scroll amount. In this way, in the communication terminal 1, the display content is scrolled and displayed by the scroll amount determined by the scroll amount determination unit 23 (S26).

  Further, the scroll amount determination unit 23 notifies the content position monitoring unit 24 of information on the determined scroll amount. By this notification, the content position monitoring unit 24 can grasp to which position the display position of the specified display area 9 moves after scrolling.

  Here, when an input of an operation instruction from the user is received (“YES” in S27), the process returns to step S24 and the process is repeated. That is, in response to an instruction from the pointer display management unit 22, the content position monitoring unit 24 identifies the position of the display range in the display area 9 in the display image range.

  Here, the display range of the display area 9 is a position moved from the initial position in the display image range of the content 15 by the scroll amount determined in step S25. Therefore, the content position monitoring unit 24 specifies that the display range of the display area 9 is in the position after movement in the display image range. Then, the scroll amount determination unit 23 determines the scroll amount assigned to the specified position based on the content 15 (S25). When the scroll amount is determined in this way, the communication terminal 1 according to the present embodiment executes the processing from step S26 onward, and the above-described processing from step S24 to S27 is repeated until no operation instruction for instructing scrolling is received. .

  Note that in the communication terminal 1, the reference point serving as the reference on the display area is located in which area of the display image range of the content 15 and the position information history after scrolling (display range position information 18) is referred to. To judge. And it was the structure which performs the scroll of the display content by the scroll amount set in each area | region.

  However, the scroll amount may be determined based on the relationship between the display position (coordinates) of the pointer in the display area 9 instead of the reference point and the position (coordinates) in the display image range corresponding to the display position.

  In such a configuration, the content position monitoring unit 24 receives information on the position of the pointer displayed in the display area 9 from the pointer display management unit 22, and this position is in any position in the display image range. The display range position information 18 is specified. In the case of such a configuration, the initial position shown in FIG. 12 is on the display image range corresponding to the display position of the pointer located at the end of the display area 9 before the display content of the content 15 is moved. Coordinates.

In the above-described “processing flow 1 and 2 of scroll display processing”, the scroll amount on the x-axis and the y-axis (horizontal axis and vertical axis) is described in the content 15. When described in this way, when the user moves his / her finger in the diagonal direction of the display area 9 on the electrostatic pad 64 as shown in FIG. 13, the communication terminal 1 according to the present embodiment The scroll amount for moving the display content in the oblique direction can be determined as follows.
FIG. 13 shows an embodiment of the present invention and is a diagram for explaining an example of scroll display processing.

  That is, it is assumed that the finger is moved on the electrostatic pad 64 in a direction (oblique direction) from the center position of the display area 9 toward the left corner in a state where the pointer is positioned at the left corner of the display area 9 as shown in FIG. The scroll amount of the display content at this time is an amount obtained by combining the scroll amounts per operation in the x-axis and y-axis directions described in the content 15, for example, as shown in FIG. When the scroll amount per operation is expressed as a vector, the vector obtained by synthesizing these vectors can be set as the scroll amount of the display content when the operation in the oblique direction is input.

  In addition, in the communication terminal 1 which concerns on this Embodiment, although it was the structure which scrolls a display content according to the movement of the finger contacted on the electrostatic pad 64, it is not limited to this structure. For example, the display content may be scrolled according to the operation of the cross key by the user.
