Description

  The present invention relates to a content display device that displays content in a display area.

  In recent years, a large screen has been developed in various devices that display content such as computers and AV devices. Up to now, only a few windows at most have been used for operations on small and medium screens, but it has become possible to display large screens, expanding the use of displaying many contents at once. Yes.

  In order to handle a large number of contents, for example, it is necessary to reduce the contents image. For example, there is a gesture operation that allows users to point and point content with two fingers and change the distance between the fingers (pinch-in / pinch-out) to reduce or enlarge the content and to compare the user with a size appropriate for viewing on a large screen. It is known (see, for example, Patent Document 1).

  In addition, recently, there is a case where a function capable of handwriting a character on a displayed content or adding a mark is installed. By adding information later, it becomes possible to make the content stand out and to record necessary instructions.

JP 2013-206317 A

  When a plurality of contents are displayed, the user may perform operations such as reducing the contents and arranging them after the reduced display.

  In this case, there is no problem just by reducing the displayed content. However, as described above, for example, when characters and marks are added, such characters and marks are also reduced and displayed. was there.

  For example, even if the content itself is marked by handwriting to indicate that it is important, if the content is reduced, the mark is also reduced and displayed. As a result, there has been a problem that the marking is not visible.

  In view of the above-described problems, the present invention is to provide a content display device or the like in which the content and the additional content associated with the content change in size at different magnifications.

In order to solve the above-described problem, the content display device of the present invention provides:
In a content display device (for example, the display device 10 in FIG. 1) that displays content in a display area,
Additional content display means (for example, control unit 110 in FIG. 2; step S114 in FIG. 4; C102 in FIG. 3) for displaying additional content on the displayed content;
Operation detecting means (for example, control unit 110 in FIG. 2; step S104 in FIG. 4) for detecting a magnification changing operation;
Content reduced display means (for example, the control unit 110 in FIG. 2; step S108 in FIG. 4) that reduces and displays the content at the first magnification detected by the change operation;
Additional content reduction display means (for example, the control unit 110 in FIG. 2; steps S154 and S156 in FIG. 5;
It is characterized by providing.

The content display method of the present invention includes:
A display method in a content display device for displaying content in a display area,
An additional content display step (for example, the control unit 110 in FIG. 2; step S114 in FIG. 4; C102 in FIG. 3) for displaying additional content on the displayed content;
An operation detection step (for example, the control unit 110 in FIG. 2; step S104 in FIG. 4) for detecting a magnification change operation;
A content reduction display step (for example, the control unit 110 in FIG. 2; step S108 in FIG. 4) for reducing and displaying the content at the first magnification detected by the change operation;
An additional content reduction display step (for example, the control unit 110 of FIG. 2; steps S154 and S156 of FIG. 5;
It is characterized by including.

  According to the present invention, when content is displayed in the display area and additional content is displayed in the content, the content is reduced and displayed by detecting a magnification change operation. At this time, the additional content displayed in association with the content is displayed at a magnification different from that of the content, that is, a magnification larger than the magnification at which the content is reduced (that is, a magnification with a low reduction rate). . As a result, it is possible to prevent the additional content from becoming smaller than necessary, and the content is displayed in an appropriate size.

  The best mode for carrying out the present invention will be described below with reference to the drawings. For convenience of explanation, the embodiment will be described as an example, but it is needless to say that any device can be applied as long as the device can perform a display operation.

[1. First Embodiment]
[1.1 Overall configuration]
FIG. 1 is a diagram showing an appearance of a display device 10 that can be operated by a touch panel to which the content display device of the present invention is applied. The display device 10 is configured integrally with a touch panel and can be operated by an operator.

  Here, the display device 10 can be operated by a plurality of operators from the size and shape of the display unit. For example, it is possible to use a business meeting facing the display or various meetings by operating from four directions.

  In the present embodiment, a touch panel is used as a display device for content. However, other devices may be used as long as they can display content and detect operations. For example, it is only necessary to be able to realize an equivalent function such as a content display system in which content is displayed by a projector and an operation on the content can be detected by detecting an operation of a space sensor or an operation pen.

[1.2 Functional configuration]
Next, the functional configuration of the display device 10 will be described with reference to FIG. As shown in FIG. 2, the display device 10 includes a control unit 110, a display unit 120, an input detection unit 130, an image processing unit 140, a communication unit 150, and a storage unit 160. .

  The control unit 110 is a functional unit for controlling the entire display device 10. The control unit 110 implements various functions by reading and executing various programs stored in the storage unit 160, and is configured by, for example, a CPU (Central Process Unit).

  The display unit 120 is a functional unit for displaying various information. For example, a liquid crystal display (LCD) or an organic EL display is used.

  The input detection unit 130 is a functional unit that can detect an input from the operator. In the present embodiment, it is formed as a touch panel integrally with the display unit 120. The input detection unit 130 can detect various operations such as tap, hold, slide, flick, pinch, and hold from the operator. In addition, it is possible to detect a plurality of inputs from the operator. For example, it may be 5 points simultaneously or 10 points simultaneously.

  Further, when the detection range is within the predetermined range and a plurality of detection points are detected, it is possible to detect that the predetermined range is selected.

  The image processing unit 140 is a functional unit for expanding content read from a file or the like, outputting a display image, or performing image processing such as a filter on the image. Here, the description of conventional image processing (for example, extracting an image to be displayed from content or simply enlarging / reducing a display image) is omitted.

  The communication unit 150 is a network interface unit for connecting to an external network of the Internet or other devices. For example, it is configured by a NIC (Network Interface Card) or the like.

  The storage unit 160 is a functional unit that stores various programs and various data necessary for the operation of the display device 10. The storage unit 160 includes, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The storage unit 160 has a main content data storage area 162 in which main contents are stored and an additional content data storage area 164 in which additional contents are stored.

  In the main content data storage area 162, content (main content) displayed on the display unit 120 is stored. This content may be, for example, character data, image data, or video data, and includes a file that can be displayed on the display unit 120 such as a PDF, a document file, or a presentation file.

  The main content may be received from another device, for example, by communication means or may be read from an external storage device. Further, it may be generated by the display device 10 or may be input by a scanner or the like.

  The main content is read from the main content data storage area and displayed on the display unit 120. A plurality of the main contents can be displayed on the display unit 120, but one may be displayed as in a full screen display, for example.

  The additional content is stored in the additional content data storage area 164 in association with the main content. The additional content is stored in association with, for example, identification information of the main content (information that can be uniquely identified such as a file ID, a file number, and a content ID).

  Various contents can be considered as the additional contents, but in the present embodiment, handwritten figures when the user performs handwriting input using the touch panel are stored. That is, data input to the handwriting input area is stored as additional data as raster data.

  Here, the relationship between the main content and the additional content will be described with reference to FIG. FIG. 3A is a diagram when the additional content is displayed superimposed on the main content. It is an example of a display screen when additional content C102 is written by hand in main content C100.

  Here, each content is displayed using each layer, for example. For example, as shown in FIG. 3B, the main content is displayed on the layer L100, and the additional content is displayed on the layer L102. By doing so, it becomes possible to reduce / enlarge and display the layer displaying the main content and the layer displaying the additional content (or additional content) at different magnifications.

  For example, when the processing of this embodiment is applied, even if the main content is reduced and displayed as shown in FIG. 3C, the additional content can be displayed in a large size. This makes it possible to make the additional content stand out as compared with the conventional case of reducing the display uniformly as shown in FIG.

[1.3 Process flow]
Subsequently, the flow of processing in the first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 shows the main processing in this embodiment.

  First, when multi-touch is detected (step S102; Yes), it is determined whether or not the operation is a reduction operation (step S104).

  If a reduction operation (for example, a pinch-in operation with two fingers) is detected, the current operation start size is stored (step S104; Yes → step S106). Then, the display magnification is determined according to the operation amount, and the resizing process is performed on the main content (step S108).

  Here, as the resizing process of the main content, the process may be executed while the main content is displayed, or only the layout frame of the size of the main content may be displayed and the size may be indicated by the layout frame. .

  This display may be either display, or may be arbitrarily selected by the user. Further, the display may be automatically switched according to the processing capability of the display device, or may be switched according to the type of content.

  Here, when the multi-touch is released (step S110; Yes), it is determined that the display magnification changing operation is completed, and the size of the main content is displayed at the current display magnification. For example, if the main content is displayed in real time in step S108, the size is determined based on the size of the main content for which multi-touch is released. When the size is indicated by the layout frame, the main content is displayed in the layout frame.

  Here, when there is additional content, additional content display processing is executed (step S114).

  Note that the reduction operation, which is one of the display magnification changing operations in FIG. 4, is determined by detecting multi-touch, but it is needless to say that other display magnification changing operations may be used. For example, other gesture inputs may be used, and other reduction operations such as touching a displayed reduction button may be detected.

  Next, the additional content display process will be described with reference to FIG. First, an additional area is specified (step S152). By specifying the additional region, the additional content is determined. For example, when the position where the additional content is input is determined, the content such as an image input to the area is determined as the additional content.

  Subsequently, a reduced image of the determined additional content is generated (step S154). Here, as a method of generating a reduced image of the additional content, the reduced image is generated so as to be equal to or larger than the display magnification (reduction magnification) of the main content.

  For example, when the main content is reduced by 70%, the additional content is reduced by 90%. This ratio may be proportional to the main content, or a process of reducing the display to a predetermined size set (for example, 100 pixels as the set size) is executed.

  Subsequently, a reduced image obtained by reducing the additional content is displayed superimposed on the main content (step S156). As a result, the main content and the additional content are displayed at different display magnifications.

  Since the purpose is to prevent the additional content from becoming smaller, the main content and the additional content may be displayed at the same magnification (reduction ratio) in the case of a predetermined size. For example, the additional content may be reduced at the same magnification up to a magnification of 95%.

[1.4 Operation example]
Subsequently, an operation example in the present embodiment will be described with reference to the drawings. FIG. 6 is an example of a display screen W100 in which main content is displayed in the region R100. Additional content is displayed in the main content. At this time, R110 in FIG. 7 and R120 in FIG. 8 indicate a state in which the pinch-in operation is performed and the main content is reduced and displayed.

  Here, FIG. 9 shows a state where the touch operation is released (a state where the reduction operation is completed). The additional content is displayed as R135 in the main content displayed in R130. R135 in which this additional content is displayed has a smaller change than the reduction rate of the main content. The main content is displayed in alignment on the display screen W100 and displayed on the upper left of the display screen W100.

  Thus, according to the present embodiment, the main content and the additional content can be displayed at different display magnifications (reduction ratios). Therefore, it is possible to prevent the additional content from being displayed smaller than expected by the user.

[2. Second Embodiment]
Next, the second embodiment will be described. The second embodiment is similar in configuration and processing to the first embodiment, but the case where vector data is used as additional content will be described.

  In the present embodiment, the additional content stored in the additional content data storage area 164 is stored as vector data. Here, when the additional content is reduced in step S154 of FIG. 5, the reduced image smaller than the original additional content is displayed by recalculating the coordinates of the vector data.

  In addition, since it is only necessary to recalculate the coordinates of the vector data based on the magnification, for example, in step S156, the coordinates may be calculated at the timing of displaying the reduced image. That is, it is only necessary to manage the magnification (reduction magnification) without generating a reduced image.

  Thus, according to the present embodiment, the operation of the first embodiment can be realized even if the additional content is vector data.

[3. Third Embodiment]
Subsequently, the third embodiment will be described. The third embodiment is similar in configuration and processing to the first embodiment, but a case where text data is used as additional content will be described.

  In the present embodiment, the additional content stored in the additional content data storage area 164 is stored as text data. As text data, for example, a position for displaying text and a character size (font size) are stored together with normal character data.

  Here, when the additional content is reduced in step S154 of FIG. 5, the additional content smaller than the original additional content is generated and displayed by changing the font size.

  In this case, image data may be used as a reduced image, or text data may be displayed based on the font size. The input of text data may use handwritten character recognition.

  That is, characters and symbols may be recognized based on handwritten data input as additional content, and the recognized characters / symbols may be stored as additional content. For example, when the user writes a “star mark”, the symbol “star” in the text data is stored as additional content.

  Thus, according to the present embodiment, the operation of the first embodiment can be realized even if the additional content is character data.

  As described in the above-described embodiment, the same processing can be executed for any data format such as raster data, vector data, and text data as additional content data. The same applies to the following embodiments.

[4. Fourth Embodiment]
Next, a fourth embodiment will be described. In the fourth embodiment, the configuration and processing are the same as those in the first embodiment, but a case where an additional content area is set as an arbitrary area, that is, a case where the additionally described content is recognized as additional content will be described. .

  In the present embodiment, an arbitrary area including additional content is specified by the additional area specifying process (step S152) in FIG. For example, the range of the input additional content may be extracted, the range including the additional content may be extracted as a rectangle, and the region may be determined as the additional region.

  Then, reduced display is executed on the additional content included in the determined additional area based on the magnification (reduction magnification).

  10 and 11 are diagrams for explaining an operation example in the present embodiment. The main content is displayed on R200 on display screen W200. On top of that, additional content is written by handwriting input by the user.

  The region R210 including the handwritten input additional content is determined as the additional region. Then, as shown by R220 in FIG. 11, the main content and the additional area including the additional content are displayed at a different magnification (reduction ratio).

[5. Fifth Embodiment]
Next, a fifth embodiment will be described. In the fifth embodiment, the configuration and processing are the same as those in the first embodiment, but a case where the additional content is divided into a plurality of regions will be described.

  In the present embodiment, an arbitrary area including additional content is specified by the additional area specifying process (step S152) in FIG. At this time, when a plurality of additional contents are input, for example, when they are separated from each other by a predetermined distance, they are recognized as different additional contents and are determined as different additional areas.

  Specifically, the additional content is input to the main content displayed on R300 of the display screen W300 in FIG. Here, the additional content is input at a position distant from R310 and R320. In this case, the additional content of R310 and the additional content of R320 are recognized as different additional content. This is because R310 and R320 are entered at predetermined positions.

  As indicated by R330 in FIG. 13, two additional contents are displayed at different magnifications (reduction ratios) in the main contents. Here, two additional areas are recognized, but different display magnifications may be used for each additional content.

  Further, a plurality of types of additional content may be combined. For example, a combination of raster data additional content and text data additional content may be used.

  In addition, as a method of determining that the additional content is different, it may be determined based on the input time. For example, when additional content included in R310 is described within a predetermined time, R310 is set as one additional content. Then, after the elapse of a predetermined time, R310 and R320 are recognized as different contents by describing the additional content of R320.

  Further, it may be recognized as different additional contents depending on the input means. For example, the area may be set based on the type of pen to be input (terminal ID), or additional content may be set by selection by the user (for example, selecting an attribute from a pull-down menu).

[6. Sixth Embodiment]
Subsequently, the sixth embodiment will be described. In the sixth embodiment, a case where reduced display is also performed in real time for additional content will be described. The configuration of the sixth embodiment is the same as that of the first embodiment, and the processing of FIGS. 4 and 5 is replaced with FIG. The same processes as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the reduction operation is started by the user (step S104; Yes), the operation start size is stored and the additional area is specified (step S202). Here, the identification of the additional region is substantially the same process as step S152 in FIG.

  Subsequently, along with the resize processing of the main content (step S108), the additional content reduction / display processing is performed (steps S204 and S206). Steps S204 and S206 are substantially the same processing as steps S154 and S156 in FIG.

  That is, in the present embodiment, in addition to displaying the main content reduced in the resizing process in step S108, the additional content reduced is displayed. As a result, the user can perform the reduction operation while confirming the actual size of the additional content.

  An operation example will be described with reference to the drawings. FIG. 15 is a diagram illustrating an example of the display screen W400. Main content R400 is displayed, and additional content R410 is displayed. Here, FIG. 16 shows a state where a reduction operation (pinch-in operation) is performed. In addition to the main content being reduced and displayed as R420, the additional content is also reduced and displayed as indicated by R430. Here, the magnification (reduction ratio) between R420 and R430 is different.

  And the case where pinch in operation is cancelled | released is FIG. Although the main content is displayed in R440, additional content with different magnifications (reduction ratios) is also displayed. As described above, in this embodiment, the user can also check the size of the additional content and perform the reduction operation.

[7. Seventh Embodiment]
Next, a seventh embodiment will be described. In the seventh embodiment, a case where additional content is reduced and displayed step by step will be described. The configuration of the seventh embodiment is the same as that of the first embodiment, and the processing of FIGS. 4 and 5 is replaced with FIG. The same processes as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the reduction operation is started by the user (step S104; Yes), the operation start size is stored and the additional area is specified (step S302). Here, the identification of the additional region is substantially the same process as step S152 in FIG.

  Subsequently, along with the resize processing of the main content (step S108), if the additional content matches the reduction condition (step S302; Yes), the additional content reduction / display processing is performed (step S302). S304, S306). Steps S304 and S306 are substantially the same processing as steps S154 and S156 in FIG.

  Here, the reduction condition is a condition for determining whether or not the additional content is reduced and displayed.

  As the reduction condition, for example, it is displayed as it is until the size of the additional content exceeds a predetermined threshold, but when the condition exceeds the threshold, reduction display is started. For example, when the threshold is set to the size of the main content, the main content is displayed in a reduced size, and the reduced display is started after the situation exceeds the main content. Moreover, the ratio with main content may be sufficient. For example, when the size ratio with the main content exceeds 90%, the reduced display is started.

  An operation example in this case will be described with reference to the drawings. FIG. 19 is a diagram showing a display screen W500 that displays a reduced display of the main content. Although the main content is displayed in R500, the additional content displayed in the main content is not reduced and displayed until it is substantially the same as the size of the main content.

  When the additional content and the main content are approximately the same size (the number of pixels in the vertical direction of the main content is the same as the number of pixels in the vertical direction of the additional area including the additional content), the additional content is reduced and displayed. The

  Accordingly, even in the main content displayed in R510 in FIG. 20, the additional content is displayed in a large size. In this case, even if the additional content is small, it is displayed in the same size as the vertical direction (or horizontal direction) of the main content.

  Further, since the additional content is reduced and displayed step by step, it may be initially reduced and displayed. In this case, the process of “Yes” and “No” is reversed in step S302 of FIG.

  For example, a process may be implemented in which reduced display is performed until one side of the number of pixels of the additional content is “100”, but the additional content is not reduced after that.

[8. Eighth Embodiment]
Next, an eighth embodiment will be described. In the eighth embodiment, an embodiment in which a method for reducing an additional content is changed by an operation method will be described. Note that this embodiment is applicable to any of the above-described embodiments. For example, the configuration is the same as that of the first embodiment, and the processing of FIGS. 4 and 5 is replaced with FIG. The same processes as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the reduction operation is started by the user (step S104; Yes), the operation start size is stored, and the additional area is specified (step S402). Here, the identification of the additional region is substantially the same process as step S152 in FIG.

  Subsequently, it is determined whether or not the second operation is detected. If the second operation is not detected (step S404; No), the main content is resized (step S108), and the additional content is reduced / displayed (steps S406 and S408). ). Steps S406 and S408 are substantially the same as steps S154 and S156 in FIG.

  If the second operation is detected (step S404; Yes), the main content and the additional content are reduced and displayed together (step S410). In other words, the main content and additional content displayed at that time will be reduced and displayed at the same magnification (reduction ratio) thereafter, and the main content and additional content will be reduced in conjunction with each other. It becomes.

  FIG. 22 is a diagram illustrating an operation example in the present embodiment. When the user performs a pinch-in operation at P, the main content displayed on R600 is reduced and displayed. At this time, the main content and the additional content displayed in the main content are displayed at different magnifications (reduction ratios).

  Here, when the user touches the screen with P2, the main content and the additional content are reduced and displayed at the same reduction rate. FIG. 23 is a diagram illustrating a state where the operation is finished. Although the main content is displayed in R610, the additional content is displayed smaller than when the reduced display is simply performed.

  As described above, according to the present embodiment, the reduction rate of the additional content can be changed according to the user's operation. The second operation may be linked with the reduction rate only while the second operation is performed, or may be linked with the reduction rate after the second operation is performed.

  In addition, by combining the fact that the second operation is performed / not performed, for example, the size of the additional content can be adjusted to an arbitrary size. As a result, the operation of changing the reduction ratio as in the first embodiment can be canceled using the second operation as a cancel operation.

[9. Ninth Embodiment]
Subsequently, a ninth embodiment will be described. In the ninth embodiment, a case where the reduction method is switched in accordance with the type of additional content will be described. The ninth embodiment has the same configuration and processing as the above-described embodiment (for example, the first embodiment).

  In the present embodiment, the magnification (reduction ratio) changes according to the type of additional content (for example, attribute information). The main content displayed on R700 of the display screen W700 in FIG. 24 displays text content and image content as additional content. For example, text content is used like a sticky note.

  Here, in the case of the present embodiment, the reduction rate for text content is more gradual than the main content, and other content (for example, content input by handwriting in the lower right star picture) is the same reduction as the main content. It is set to reduce the display at a rate.

  In this case, like the main content displayed in R710 of FIG. 25, the text content is displayed large, but the handwritten content is displayed small. In this way, the reduction ratio can be changed according to the content attribute.

  Here, the content attribute may be the type of content or the attribute (identification ID) of the person who wrote the content. In addition, an importance attribute such as an importance mark may be used, or a handwritten input shape may be automatically recognized and an importance attribute may be added.

[10. Tenth Embodiment]
Subsequently, a tenth embodiment will be described. In the tenth embodiment, a case where another process is executed according to the additional content will be described.

  That is, as a process following the above-described embodiment, each process may be executed based on the added content.

  For example, four main contents are displayed on the display screen W800 of FIG. That is, although R800, R810, R820, and R830 are displayed, additional contents displayed on R800 and R830 are substantially the same.

  Whether or not the additional content is the same may be determined by detecting, for example, substantially the same shape, or may be determined by the type of the additional content. Also, the same character / symbol recognized from the input additional content may be determined as the same additional content.

  In this case, for example, a selection process as shown in FIG. 27 can be performed. That is, it is possible to perform processing such as selecting main content on which substantially the same additional content is displayed (filled in).

  Then, it is possible to execute processing such as arranging the selected contents as shown in FIG. 28 or storing them as shown in FIG.

[11. Eleventh Embodiment]
Next, an eleventh embodiment will be described. The eleventh embodiment is an embodiment in the case of suppressing the additional content from being unnecessarily enlarged when the main content is enlarged.

  In the above-described embodiment, the case where the main content and the additional content are reduced as an example in which different magnifications are applied has been described. Applying this different magnification can also be applied to enlargement processing.

  Specifically, when enlarging the main content, a process of enlarging the additional content at a lower magnification than that may be executed. That is, it is possible to prevent the additional content from being displayed too large.

  FIG. 30 is an enlarged view of content (R900). For example, text content is displayed in R910 as additional content. By performing a pinch-out operation, the main content is enlarged and displayed, but the size of the additional content is suppressed as indicated by R910.

  When this embodiment is not applied, text content as additional content is displayed large as shown in FIG. Compared to this, in FIG. 30, the image is enlarged at an appropriate size, and display of an unnecessarily large image is suppressed.

[12. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.

  In the above-described embodiment, a large content display device has been described. However, a small content display device or a terminal such as a tablet may be used. Needless to say, the present invention can also be realized in other devices such as a TV capable of touch input and a car navigation system.

  Further, although the above-described embodiments are described separately for convenience of description, they may be combined and operated through the specification as necessary. For example, even in the embodiment described as vector data, additional content may be characters or symbols as additional content. Additional content input by handwriting is recognized as text, and the additional content is stored as characters or symbols. Of course, it may be.

  In addition, the program that operates in each device in the embodiment is a program (a program that causes a computer to function) that controls the CPU and the like so as to realize the functions of the above-described embodiments. Information handled by these devices is temporarily stored in a temporary storage device (for example, RAM) at the time of processing, then stored in various ROM or HDD storage devices, and read and corrected by the CPU as necessary. • Writing is performed.

  Here, as a recording medium for storing the program, a semiconductor medium (for example, ROM, a non-volatile memory card, etc.), an optical recording medium / a magneto-optical recording medium (for example, a DVD (Digital Versatile Disc), MO (Magneto Optical), etc. Disc), MD (Mini Disc), CD (Compact Disc), BD, etc.), magnetic recording medium (eg, magnetic tape, flexible disk, etc.), etc. In addition, by executing the loaded program, not only the functions of the above-described embodiment are realized, but also based on the instructions of the program, the processing is performed in cooperation with the operating system or other application programs. The functions of the invention may be realized.

  In addition, when distributing to the market, the program can be stored and distributed in a portable recording medium, or transferred to a server computer connected via a network such as the Internet. In this case, of course, the storage device of the server computer is also included in the present invention.

  In addition, a part or all of each device in the above-described embodiments may be realized as an LSI (Large Scale Integration) that is typically an integrated circuit. Each functional block of each device may be individually chipped, or a part or all of them may be integrated into a chip. Further, the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. In addition, when integrated circuit technology 3 replaces LSI appears due to progress in semiconductor technology, it is of course possible to use an integrated circuit based on the technology.
