Description

  The present invention relates to a content display device that displays content in a display area, and the like.

  2. Description of the Related Art In recent years, screens of various devices for displaying contents, such as computers and AV devices, have been increasing in size. Until now, operations on the small and medium screens had to be performed by displaying at most a few windows at most, but large-screen display is now possible, and the use of displaying many contents at once has expanded. I have.

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

  In addition, recently, a function capable of writing characters by hand on a displayed content or adding a mark may be installed. By adding the information later, it is possible to make the contents 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 displaying the contents in a reduced size or arranging the contents after the reduced display.

  In this case, there is no problem simply by reducing the displayed content. However, for example, as described above, 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 hand at the upper left of the content to indicate that it is important, when the content is reduced, the mark is also reduced and displayed. As a result, there has been a problem that the marking becomes invisible.

  In view of the above-described problem, an object of the present invention is to provide a content display device or the like in which the size changes at a different magnification between the content and the additional content associated with the content.

In order to solve the above-described problems, a content display device of the present invention
In a content display device that displays content in a display area (for example, the display device 10 in FIG. 1),
Additional content display means (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;
Operation detection means (for example, control unit 110 in FIG. 2; step S104 in FIG. 4) for detecting a magnification change operation;
Content reduction display means (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 unit (for example, the control unit 110 in FIG. 2; steps S154 and S156 in FIG. 5; R135 in FIG. 9) for reducing and displaying the additional content at a second magnification equal to or higher than the first magnification.
It is characterized by having.

Further, the content display method of the present invention includes:
A display method in a content display device that displays content in a display area,
An additional content display step of displaying additional content on the displayed content (for example, control unit 110 in FIG. 2; step S114 in FIG. 4; C102 in FIG. 3);
An operation detecting step of detecting a magnification changing operation (for example, the control unit 110 in FIG. 2; step S104 in FIG. 4);
A content reduction display step of reducing and displaying the content at the first magnification detected by the change operation (for example, the control unit 110 in FIG. 2; step S108 in FIG. 4);
An additional content reduction display step of reducing and displaying the additional content at a second magnification equal to or higher than the first magnification (for example, the control unit 110 in FIG. 2; steps S154 and S156 in FIG. 5; R135 in FIG. 9);
It is characterized by including.

  According to the present invention, when a content is displayed in a display area and an additional content is displayed on 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 has been reduced (ie, a magnification with a lower reduction ratio). . As a result, it is possible to prevent the additional content from being unnecessarily small, and the content is displayed in an appropriate size.

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

[1. First Embodiment]
[1.1 Overall configuration]
FIG. 1 is a diagram showing the 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 based on the size and shape of the display unit. For example, it is possible to use business negotiations facing a display or use it in various meetings by operating from four directions.

  In this embodiment, a touch panel is used as the display device for the content. However, another device may be used as long as the content is displayed and the operation can be detected. For example, any device capable of realizing equivalent functions such as a content display system capable of displaying content by a projector and detecting an operation on the content by detecting an operation of a space sensor or an operation pen or the like may be used.

[1.2 Functional Configuration]
Subsequently, a 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 realizes various functions by reading and executing various programs stored in the storage unit 160, and includes, for example, a CPU (Central Process Unit) or the like.

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

  The input detection unit 130 is a functional unit that can detect an input from the operator. In the present embodiment, the touch panel is formed 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. Further, it is possible to detect a plurality of inputs from the operator. For example, five points may be simultaneous or ten points may be simultaneous.

  If 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 the 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 the 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 and 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 necessary for the operation of the display device 10 and various data. The storage unit 160 includes, for example, a semiconductor memory, a hard disk drive (HDD), and the like.

  Further, the storage section 160 has a main content data storage area 162 in which main content is stored, and an additional content data storage area 164 in which additional content is stored.

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

  The main content may be received from another device by, for example, a communication unit, or may be read from an external storage device. Further, it may be generated by the display device 10 or 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. Although a plurality of the main contents can be displayed on the display unit 120, one main content may be displayed as in a full screen display, for example.

  Then, 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 (uniquely identifiable information such as a file ID, a file number, and a content ID).

  Various contents can be considered as the additional contents. In the present embodiment, a handwritten figure when the user performs handwriting input using the touch panel is stored. That is, data input to the handwriting input area is stored as raster data as additional content.

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

  Here, each content is displayed using, for example, each layer. 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 is possible to reduce / enlarge the layer displaying the main content and the layer displaying the additional content (or the additional content) at different magnifications.

  For example, when the processing of the present embodiment is applied, as shown in FIG. 3C, even if the main content is reduced and displayed, 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 uniformly reducing the size as shown in FIG. 3D.

[1.3 Processing Flow]
Next, the flow of processing in the first embodiment will be described with reference to FIGS. FIG. 4 shows the main processing in the present embodiment.

  First, when a 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 performed 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. .

  Either of these displays may be used, or the user may arbitrarily select this display. 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 change operation has been 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 by the size of the main content from which multi-touch has been released. When the size is indicated by the layout frame, the main content is displayed in the layout frame.

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

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

  Next, the additional content display processing will be described with reference to FIG. First, an additional area is specified (step S152). By specifying the additional area, the additional content is determined. For example, when the position where the additional content is input is determined, the content such as the 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 and displayed by 70%, a process is performed such that 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 (for example, 100 pixels as the set size) is executed.

  Subsequently, a reduced image obtained by reducing the additional content is displayed so as to be 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) when the size is a predetermined size. For example, up to a 95% magnification, the additional content may also be reduced at the same magnification.

[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 the display screen W100 in which the main content is displayed in the region R100. The additional content is displayed as the main content. At this time, R110 in FIG. 7 and R120 in FIG. 8 show a state in which the pinch-in operation is performed and the main content is reduced and displayed.

  Here, FIG. 9 illustrates a state in which the touch operation is released (a state in which the reduction operation is completed). The additional content is displayed as R135 in the main content displayed in R130. The change of R135 in which the additional content is displayed is smaller than the reduction rate of the main content. Further, the main contents are arranged and displayed on the display screen W100, and are displayed at the upper left of the display screen W100.

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

[2. Second Embodiment]
Next, a second embodiment will be described. Although the second embodiment has the same configuration and processing as the first embodiment, a case will be described in which vector data is used as additional content.

  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, a reduced image smaller than the original additional content is displayed by recalculating the coordinates of the vector data.

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

  As described above, 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]
Next, a third embodiment will be described. Although the third embodiment has the same configuration and processing as the first embodiment, a case in which 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 the text data, for example, the position where the text is displayed and the character size (font size) are stored together with the normal character data.

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

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

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

  As described above, 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 in any data format such as raster data, vector data, and text data as the data of the additional content. The same applies to the following embodiments.

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

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

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

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

  The region R210 including the additional content of the handwritten input is determined as the additional region. Then, as indicated by R220 in FIG. 11, the display is performed at a different magnification (reduction ratio) from the main content and the additional area including the additional content.

[5. Fifth Embodiment]
Next, a fifth embodiment will be described. The fifth embodiment has the same configuration and processing as the first embodiment, but a case will be described in which the additional content is divided into a plurality of areas.

  In the present embodiment, an arbitrary area including the additional content is specified by the additional area specifying process (step S152) in FIG. At this time, if a plurality of additional contents have been input, for example, if they are separated 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 display screen W300 in FIG. Here, the additional content is input at a position separated from R310 and R320. In this case, it is recognized that the additional content of R310 is different from the additional content of R320. This is because R310 and R320 are written at a predetermined distance from each other.

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

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

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

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

[6. Sixth embodiment]
Next, a sixth embodiment will be described. In the sixth embodiment, a case will be described in which reduced display is performed in real time also on additional content. The sixth embodiment has the same configuration as the first embodiment, and is obtained by replacing the processing in FIGS. 4 and 5 with FIG. Note that the same processes as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof will be 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 specification of the additional area is substantially the same processing as step S152 in FIG.

  Subsequently, the resizing process of the main content is performed (step S108), and the process of reducing and displaying the additional content is performed (steps S204 and S206). Steps S204 and S206 are substantially the same as steps S154 and S156 in FIG.

  That is, in the present embodiment, in addition to displaying the content whose main content has been reduced by the resizing process in step S108, the reduced content of the additional content is displayed. This allows the user to perform a reduction operation while checking the size of the actual 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. The main content R400 is displayed, and the additional content R410 is displayed. Here, FIG. 16 shows a state in which the reduction operation (pinch-in operation) is being performed. In addition to the main content being displayed in a reduced size as R420, the additional content is also displayed in a reduced size as indicated by R430. Here, the magnification (reduction ratio) between R420 and R430 is different.

  FIG. 17 shows a case where the pinch-in operation is released. Although the main content is displayed on R440, additional contents having different magnifications (reduction rates) are also displayed. As described above, in the present embodiment, it is also possible for the user to perform the reduction operation while checking the size of the additional content.

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

  When the user starts the reduction operation (Step S104; Yes), the operation start size is stored, and the additional area is specified (Step S302). Here, the specification of the additional area is substantially the same processing as step S152 in FIG.

  Subsequently, in addition to the resizing process of the main content being performed (step S108), if the additional content matches the reduction condition (step S302; Yes), the additional content is reduced and displayed (step S302). S304, S306). Steps S304 and S306 are substantially the same as steps S154 and S156 in FIG.

  Here, the reduction condition is a condition for determining whether the additional content is displayed in a reduced size.

  As the reduction condition, for example, the size of the additional content is displayed as it is until the size exceeds a predetermined threshold, but when the condition exceeds the threshold, the 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 a situation exceeding the main content is reached. Further, it may be a ratio to the main content. For example, when the size ratio with the main content exceeds 90%, 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 displaying a reduced display of the main content. The main content is displayed on the R500, but the additional content displayed on the main content is not displayed in a reduced size until the size of the additional content becomes substantially the same as the size of the main content.

  When the additional content and the main content have substantially the same size (the number of vertical pixels of the main content and the number of vertical pixels of the additional area including the additional content are the same), the additional content is reduced and displayed. You.

  Therefore, 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 main content in the vertical (or horizontal) direction.

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

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

[8. Eighth embodiment]
Next, an eighth embodiment will be described. The eighth embodiment describes an embodiment in which the method of reducing the additional content is changed according to the operation method. 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. Note that the same processes as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof will be 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 specification of the additional area is substantially the same as the processing in step S152 in FIG.

  Subsequently, it is determined whether the second operation has been detected. If the second operation has not been detected (step S404; No), the resizing process of the main content is performed (step S108), and the process of reducing and displaying the additional content is performed (steps S406 and S408). ). Steps S406 and S408 are substantially the same as steps S154 and S156 in FIG.

  Here, when the second operation is detected (Step S404; Yes), the main content and the additional content are reduced and displayed integrally (Step S410). In other words, for the main content and the additional content displayed at that time, the image is reduced and displayed at the same magnification (reduction rate) thereafter, and the main content and the additional content are reduced and displayed in conjunction with each other. Becomes

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

  Here, when the user touches the screen at P2, the main content and the additional content are reduced and displayed at the same reduction ratio. FIG. 23 is a diagram showing a state in which the operation has been completed. Although the main content is displayed on R610, the additional content is displayed smaller than when simply reduced display is performed.

  As described above, according to the present embodiment, the reduction ratio of the additional content can be changed according to the operation of the user. Further, in the second operation, the reduction ratio may be linked only while the second operation is being performed, or the reduction ratio may be linked after the second operation is performed.

  Further, by combining performing / not performing the second operation, for example, it is possible to adjust the size of the additional content to an arbitrary size. As a result, the operation of changing the reduction ratio as in the first embodiment can be canceled by using the second operation as a cancel operation.

[9. Ninth embodiment]
Next, a ninth embodiment will be described. The ninth embodiment describes a case where the reduction method is switched according to the type of the additional content. 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 the 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 ratio of the text content is slower than that of the main content, and the other content (for example, the content input by handwriting the picture of the star at the lower right) is the same as the main content. The display is set to be reduced at the 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. Thus, it is possible to change the reduction ratio according to the attribute of the content.

  Here, the attribute of the content may be a type of the content or an attribute (identification ID) of a person who wrote the content. An importance attribute such as an important mark may be used, or a handwritten input form 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 will be described where another process is executed according to the additional content.

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

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

  Whether or not the additional contents are the same may be determined by detecting, for example, substantially the same shape, or may be determined by the type of the additional content. In addition, those in which the characters and symbols recognized from the input additional content are the same 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 a process of selecting a main content on which substantially the same additional content is displayed (written).

  Then, it becomes 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]
Subsequently, an eleventh embodiment will be described. The eleventh embodiment is an embodiment in which, when the main content is enlarged, the additional content is suppressed from being unnecessarily enlarged.

  The above embodiment has described the case where the main content and the additional content are reduced as an example in which different magnifications are applied. The application of different magnifications can also be applied to enlargement processing.

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

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

  If the present embodiment is not applied, as shown in FIG. 31, the text content as the additional content is displayed large. Compared to this, in FIG. 30, the image is enlarged at an appropriate size, and unnecessary display is suppressed.

[12. Modification]
The embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments, and a design or the like without departing from the gist of the present invention is set forth in the appended 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. Further, it is needless to say that the present invention can be realized in other devices such as a television and a car navigation that can perform touch input.

  In addition, the above-described embodiments are described separately for convenience of description, but may be combined with each other and operated as needed. For example, as the additional content, even in the embodiment described as vector data, a character or a symbol may be used as the additional content. Of course, it may be possible.

  In the embodiment, the program that operates in each device is a program that controls a CPU or the like (a program that causes a computer to function) so as to realize the functions of the above-described embodiments. The information handled by these devices is temporarily stored in a temporary storage device (for example, a RAM) at the time of processing, and thereafter stored in a storage device such as various ROMs and HDDs. -Writing is performed.

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

  When the program is to be distributed in the market, the program can be stored in a portable recording medium and distributed, or transferred to a server computer connected via a network such as the Internet. In this case, it goes without saying that the storage device of the server computer is also included in the present invention.

  Further, a part or all of each device in the above-described embodiment may be realized as an LSI (Large Scale Integration) which is typically an integrated circuit. Each functional block of each device may be individually formed into a chip, or a part or the whole 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, in the case where an integrated circuit technology 3 that replaces the LSI appears with the advance of the semiconductor technology, it goes without saying that an integrated circuit based on the technology can be used.
