DESCRIPTION OF EMBODIMENT

Thanks to the features, multiple page images and an in-folder-icon image are displayed on the screen. This makes it possible to display icons in different hierarchies on the same screen. Hence, the user can efficiently carry out an icon editing task.

For example, the page images each include icon display areas capable of displaying the icons, and the image display control device further includes a third display control unit which, when the receiving unit receives an operation signal for selecting an icon display area which displays no icon, displays a folder icon in the selected icon display area.

Thanks to the features, the user can make a folder icon by simply operating a directional key to move a cursor to an icon display area with no icon displayed and pressing an enter key. Hence, the user can efficiently carry out an icon editing task using an input apparatus such as a remote control equipped with limited keys.

Moreover, the third display control unit may further display, on the screen, an image for entering a name by a user, and designate a name, which is entered by the user and identified by an operation signal received by the receiving unit, as a name of the folder icon displayed in the selected icon display area.

Thanks to the features, the user can name a folder icon.

For example, the above image display control device includes a fourth display control unit which displays, on the screen, an icon list image presenting a list of the icons displayable on the screen.

In addition, when the receiving unit receives an operation signal for selecting an icon from among the icons in the icon list image and the selected icon is associated with a folder icon, (i) the first display control unit may further highlight the folder icon associated with the selected icon and included in the page images, and (ii) the second display control unit may further display the in-folder-icon image of the highlighted folder icon.

When the user selects an icon included in the icon list image, such features allow the folder icon including the selected icon to be highlighted. Hence, the user can easily find out that the icon is included in which folder icon on which page image.

For example, the above image display control device further includes a position changing unit which switches display positions between two of the icons on the screen when the receiving unit receives an operation signal for selecting one of the two icons and then an other one icon, the icons being displayed in the page images and in the icon list image.

Thanks to the features, the user can switch the display positions of two icons through a simple operation to successively select the two icons. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

Moreover, the position changing unit may further move, on the screen, one of the icons to one of the icon display areas which displays no icon, when the receiving unit receives an operation signal for selecting the one icon and then the one icon display area, the icons being displayed in the page images and in the icon list image, and the icon display areas being capable of displaying the icons in the page images and in the icon list image.

Thanks to the features, the user can move an icon through a simple operation to select the icon and then an empty area. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

In addition, the position changing unit may further move, on the screen, one of the icons to the in-folder-icon image, when the receiving unit receives an operation signal indicating an operation which keeps selecting the one icon for a certain period of time or longer, the icons being displayed in the page images while the in-folder-icon image is displayed.

Thanks to the features, the user can move an icon to the in-folder-icon image by operating a directional key to move a cursor to the icon in a page image and then holding an enter key pressed. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

Moreover, the position changing unit may further move, on the screen, one of the icons to one of the icon display areas which displays no icon, when the receiving unit receives an operation signal indicating an operation which keeps selecting the one icon in the in-folder-icon image for a certain period of time or longer, the icon display areas being capable of displaying the icons in the page images.

Thanks to the features, the user can move an icon to an empty area in a page image by operating a directional key to move a cursor to the icon in an in-folder-icon image and then holding an enter key pressed. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

Moreover, when the receiving unit receives an operation signal for selecting a name of a folder icon included in the in-folder-icon image, the second display control unit may further display, on the screen, an image for entering a name by a user, and designate a name, which is entered by the user and identified by an operation signal received by the receiving unit, as a name of the folder icon.

Thanks to the features, the user can change the name of a folder icon.

In addition, the image display control device further may include a deletion control unit which deletes from the screen a folder icon displayed on the screen, when the receiving unit receives an operation signal for indicating an operation which keeps selecting the one folder icon for a certain period of time or longer.

Thanks to the features, the user can delete a folder icon by operating a directional key to move a cursor to the folder icon and then holding an enter key pressed. Hence, the user can efficiently delete a folder icon using an input apparatus such as a remote control equipped with limited keys.

[1-1 Structure]

FIG. 1 represents a block diagram illustrating a structure of animage display system10 according to an embodiment.

Theimage display system10 is used for displaying an image including an icon and editing the icon. Theimage display system10 includes adisplay unit30, an imagedisplay control device20, and aremote control31.

Thedisplay unit30 includes a display and so on, and displays an image on a screen.

The imagedisplay control device20 executes control for displaying on thedisplay unit30 an image including an icon. More specifically, the imagedisplay control device20 downloads through anetwork connecting unit29 application software (hereinafter simply referred to as “application”) to be executed on the imagedisplay control device20. The imagedisplay control device20 then executes control for displaying, on the screen of thedisplay unit30, an icon indicating the downloaded application. The imagedisplay control device20 carries out an icon editing task including creating an icon and moving the position of an icon, by following a user operation via theremote control31. Specifically, the imagedisplay control device20 is one of the following application-executable devices: a recording appliance such as a hard-disk drive recorder, a TV, and a personal digital assistance.

Theremote control31 wirelessly transmits the imagedisplay control device20 an operation signal indicating a user operation.

FIG. 2 represents an appearance diagram of theremote control31.

Theremote control31 includes a directional key32 for moving a cursor and anenter key33 for determining an operation, as well as a button for operating the channels on the TV and a button for operating the recording appliance.

The imagedisplay control device20 includes thenetwork connecting unit29, a receivingunit28, and acontrol unit21.

Thenetwork connecting unit29 is a communications appliance including a network interface card and so on for connecting the imagedisplay control device20 to networks such as the Internet and a local area network (LAN).

The receivingunit28 receives an operation signal to be transmitted from theremote control31. Specifically, the receivingunit28 receives from theremote control31 an operation signal indicating a user operation directed to an icon displayed on the screen of thedisplay unit30.

Thecontrol unit21 displays on thedisplay unit30 an icon indicating the application downloaded by thenetwork connecting unit29, and carries out an icon editing task in response to the operation signal received by the receivingunit28.

Thecontrol unit21 includes a firstdisplay control unit22, a seconddisplay control unit23, a thirddisplay control unit24, a fourthdisplay control unit25, aposition changing unit26, and adeletion control unit27.

The firstdisplay control unit22 displays, on the screen of thedisplay unit30, multiple page images each including an icon.

The seconddisplay control unit23 displays, on the screen of thedisplay unit30, an in-folder-icon image presenting at least one icon associated with a folder icon which is a kind of icon.

When the receivingunit28 receives an operation signal for selecting an icon display area which displays no icon, the thirddisplay control unit24 displays a folder icon in the selected icon display area. It is noted that, the icon display area is capable of displaying an icon included in each of the page images.

The fourthdisplay control unit25 displays, on the screen of thedisplay unit30, an icon list image presenting a list of icons displayable on the screen.

Theposition changing unit26 changes the display position of an icon on the screen of thedisplay unit30.

Thedeletion control unit27 deletes, from the screen of thedisplay unit30, an icon displayed on the screen.

Detailed hereinafter are operations of the imagedisplay control device20, with reference to the drawings.

FIG. 3 represents an example of a screen (hereinafter referred to as “operating screen”) displayed in the initial state by thecontrol unit21 on thedisplay unit30. The operatingscreen displays icons101 to108 included in a given page. Each of the icons is associated with an application. For example, each of theicons102 to104 is associated with a game application. Theicon101 is associated with an application for icon editing tasks.

In order to switch the page displayed on the operating screen, the user operates the directional key32 on theremote control31 to move the cursor to abutton111 or abutton112, and presses theenter key33. In response to an operation signal transmitted via such an operation, thecontrol unit21 switches pages and displays on thedisplay unit30 an icon included in the page switched to. In other words, the user can look for a desired icon while switching pages, and execute a desired application.

When the user executes the application indicated by theicon101, thecontrol unit21 displays, on thedisplay unit30, a screen (hereinafter referred to as “editing screen”) for icon editing tasks as represented inFIG. 4. In other words, the firstdisplay control unit22

displays page images

204 to206 on the editing screen. The fourthdisplay control unit25 displays anicon list image201 on the editing screen. Thepage image204 includesicons207 to213. Similar to thepage image204, each of the

page images

205 and206 includes multiple icons.FIG. 4 shows three page images alone. In order to display the fourth page image and after, the user operates thedirectional key32 of theremote control31 downward. When the user operates the directional key32 downward while the cursor is pointing to a bottom icon on thepage image206, the firstdisplay control unit22 scrolls down to a succeeding page image. Such an operation makes it possible to display the fourth page image and after. It is noted that when the user scrolls images to redisplay a page image disappeared from the editing screen, the user can scroll up to a preceding page image by operating the directional key32 upward.

Theicon list image201 includes anicon202 and acheck box203 for selecting whether or not theicon202 is to be displayed on the page image. Theicon list image201 displays all the icons registered in the imagedisplay control device20. When the user checks thecheck box203, theicon202 that is associated with thecheck box203 is displayed on a given page image. When the user checks thecheck box203 for theicon202, for example, theicon209 is displayed on thepage image204. Selection and deselection of thecheck box203 are made as described below. When the user operates thedirectional key32 of theremote control31 to move the cursor to the positions of thecheck box203 and theicon202 and presses theenter key33, the user makes a binary selection between on and off as a toggle. It is noted that when the user displays an undisplayed icon on theicon list image201, the user may operate the directional key32 upward or downward as does so for page images. Such a feature allows the user to scroll and display an icon within theicon list image201.

[1-2. Operations]

FIGS. 5A to 5C represent flowcharts depicting processes executed by the imagedisplay control device20 when the editing screen is displayed.

Described next is how to edit a folder, with reference to the flowcharts inFIGS. 5A to 5C and exemplary editing screens.

It is noted that the imagedisplay control device20 is to be set to one of a swap mode and a non-swap mode. The swap mode and the non-swap mode shall be described later. In the initial state, the imagedisplay control device20 is in the non-swap mode.

The receivingunit28 receives an operation signal from the remote control31 (S2).

If the received operation signal is the operation signal transmitted from theremote control31 by the user pressing the directional key32 (S4: YES), thecontrol unit21 moves the cursor on the editing screen in a direction in which the directional key is pressed (S6).

[1. Creating a Folder]

FIG. 6 represents a portion of thepage image204. For example, if acursor301 moves to an icon display area with no icon displayed and sets focus on the position (S8: YES), the thirddisplay control unit24 displays a translucent folder icon in the focused icon display area (S10).

Here, if the user presses theenter key33 of the remote control31 (S20: YES, S24: NO, S38: NO, and S44: YES), the thirddisplay control unit24 displays, on the screen, aname entering image311 represented inFIG. 7. The user operates the directional key32 and theenter key33 on thename entering image311 in order to name the folder icon, and the thirddisplay control unit24 displays the named folder icon on the focused icon display area (S46). Such processes make a new folder icon.

[Highlighting an Icon]

FIG. 8 represents an example of how to highlight an icon. For example, if the user operates thedirectional key32 of theremote control31 to move acursor401 to an icon in theicon list image201 so that thecursor401 sets focus on the position (S12: YES), the firstdisplay control unit22 highlights afolder icon402 including the focused icon. For example, the firstdisplay control unit22 presents the background of thefolder icon402 brighter than that of another icon. In addition, the seconddisplay control unit23 displays an in-folder-icon image403 to display therein icons included in thefolder icon402. Then, the seconddisplay control unit23 highlights anicon404 which is the same as the icon that thecursor401 locates (S14). For example, the seconddisplay control unit23 presents the background of theicon404 brighter than that of another icon. It is noted that when atarget folder icon402 to be highlighted is not displayed on the screen, the firstdisplay control unit22 scrolls page images and highlights atarget folder icon402 on the screen. In the case where theicon404 is not displayed on the in-folder-icon image403, as well, the seconddisplay control unit23 scrolls icons and highlights thetarget icon404 on the in-folder-icon image403.

In the state ofFIG. 8, when the user operates leftward thedirectional key32 of the remote control31 (S4: YES), acursor405 moves to the position of the top-left icon on thepage image204 as represented inFIG. 9 (S6). In addition, the seconddisplay control unit23 hides the in-folder-icon image403 (S8: NO, S12: NO, S16: YES, and S18).

[3. Expanding a Folder Icon]

FIG. 10 represents a case where acursor501 is positioned on a folder icon. In the state ofFIG. 9, for example, when the user operates rightward thedirectional key32 of the remote control31 (S4: YES), acursor501 moves right as represented inFIG. 10 (S6). Here, if the user presses theenter key33 of the remote control31 (S20: YES, S24: NO, S38: NO, S44: NO, and S48: YES), the seconddisplay control unit23 displays the in-folder-icon image403 on the screen as represented inFIG. 11 (S50). The in-folder-icon image403 includesicons404 to408 included in a folder icon which thecursor501 locates. The firstdisplay control unit22 shifts leftward the display positions of thepage images204 to206 by the predetermined number of pixels, in order to secure the display area of the in-folder-icon image403.

[4. Moving an Icon]

FIG. 12 represents how to move an icon.

Described first is how to switch display positions between two icons. Two icons switch their display positions when one of the icons is selected and then the other icon is selected. Exemplified is how to switch display positions between anicon604 and anicon605 on thepage image205. The user operates thedirectional key32 of theremote control31 to move a cursor onto anicon604, and presses the enter key33 (S20: YES, S24: NO, and S38: YES). Then, the imagedisplay control device20 changes to the swap mode (S40). The swap mode is the state where an icon to move is selected. The imagedisplay control device20 can be set to the other mode—that is the non-swap mode. The non-swap mode is the state where an icon to move is not selected. After changing to the swap mode, theposition changing unit26 designates a selectedicon604 as a first icon (S42). Next, the user operates thedirectional key32 of theremote control31 to move a cursor onto anicon605, and presses the enter key33 (S20: YES, S24: YES, and S26: YES). Then, theposition changing unit26 designates the selectedicon605 as a second icon (S28), and switches, on the screen, the display positions of the selectedicon604 designated as the first icon and theicon605 designated as the second icon (S30). Then, the imagedisplay control device20 changes to the non-swap mode (S32). Such operations make it possible to switch display positions of two icons. It is noted that icons to be switched shall not be limited to regular icons; instead, those icons may be folder icons.

Described below is how to switch display positions between afolder icon602 and theicon605. Exemplified here is a case where afolder icon602 is selected and then theicon605 is selected so that the display positions of the two icons switch. If the user operates theremote control31 to move a cursor onto afolder icon602 and presses theenter key33 when the in-folder-icon image403 is not displayed (S20: YES, S24: NO, S38: NO, S44: NO, and S48: YES), the seconddisplay control unit23 displays the in-folder-icon image403 as represented inFIG. 12 (S50). Here, if the user presses theenter key33 of theremote control31 again (S20: YES, S24: NO, and S38: YES), the imagedisplay control device20 changes to the swap mode (S40). After changing to the swap mode, theposition changing unit26 designates the selectedfolder icon602 as the first icon (S42). Next, the user operates thedirectional key32 of theremote control31 to move the cursor onto theicon605, and presses the enter key33 (S20: YES, S24: YES, and S26: YES). Then, theposition changing unit26 designates the selectedicon605 as the second icon (S28), and switches, on the screen, the display positions of thefolder icon602 designated as the first icon and theicon605 designated as the second icon (S30). After that, the imagedisplay control device20 changes to the non-swap mode (S32). Such operations make it possible to switch the display positions between thefolder icon602 and theicon605. The display positions can be switched when theicon605 is selected first, followed by thefolder icon602.

Icons whose positions are switchable shall not be limited to two of the icons on a page image; instead, the switchable icons may be two of the icons in the in-folder-icon image403 and may be an icon on a page image and another icon in the in-folder-icon image403. For example, the user can switch theicon406 and theicon408 both included in the in-folder-icon image403. Furthermore, the user can switch theicon605 on thepage image205 and theicon404 in the in-folder-icon image403. In other words, as soon as either a regular icon or a folder icon displayed in the in-folder-icon image403 is selected (S38: YES), the imagedisplay control device20 changes to the swap mode (S40). The selected icon is designated as the first icon (S42). The icon selected next is designated as the second icon (S26: YES, and S28). The display positions between the first and the second icons switch (S30). The imagedisplay control device20 changes to the non-swap mode (S32). Such operations make it possible to switch the display positions of two icons.

Described next is how to move an icon to an empty area. An icon moves to an empty area when the user selects the icon and then selects the empty area with no icon located. Exemplified here is a case where theicon404 is moved to anicon display area603 found on thepage image204 and displaying no icon. The user operates thedirectional key32 of theremote control31 to move a cursor onto theicon404, and presses the enter key33 (S20: YES, S24: NO, and S38: YES). Then, the imagedisplay control device20 changes to the swap mode (S40). After changing to the swap mode, theposition changing unit26 designates the selectedicon404 as the first icon (S42). Next, the user operates thedirectional key32 of theremote control31 to move the cursor onto anicon display area603, and presses the enter key33 (S20: YES, S24: YES, S26: NO, and S34: YES). Hence, theposition changing unit26 moves, on the screen, theicon404 designated as the first icon to the icon display area603 (S36). After that, the imagedisplay control device20 changes to the non-swap mode (S32). Such operations make it possible to move the icon to the empty area. It is noted that switchable icons shall not be limited to regular icons; instead, the switchable icons may be folder icons. In addition, an empty area shall not be limited to an icon display area on a page image; instead, the empty area may be theicon display area410 found on the in-folder-icon image403 and displaying no icon. For example, theicon605 on thepage image205 can be moved to theicon display area410 on the in-folder-icon image403. Moreover, an icon can be moved within thepage image205, as well as within the in-folder-icon image403.

[5. Changing the Name of a Folder Icon]

A folder is named when the folder is made (FIG. 7 and S46 inFIG. 5C). For example, the user originally named a folder icon “Game” since the folder icon included multiple game-related icons. Then, the user might desire to change the name of the folder icon to “News” when the user changed the content of the folder icon from the game-related icons to a news-related icon. AsFIG. 13 represents, when the user changes the name of a folder icon, the user operates thedirectional key32 of theremote control31 to move acursor701 to the name of the folder icon in the in-folder-icon image403 (S2, S4: YES, and S6 inFIG. 5A). While thecursor701 is on the name, the user presses the enter key33 (S20: YES, S24: NO, S38: NO, S44: NO, S48: NO, and S52: YES). Then, the seconddisplay control unit23 displays aname entering image702 as represented inFIG. 14. The user can enter a name by operating the directional key32 and theenter key33 on thename entering image702. The seconddisplay control unit23 changes the name of the folder icon to the entered name (S54).

On the screen represented inFIG. 12, suppose the user operates thedirectional key32 of theremote control31 to move a cursor to thefolder icon602, and, while the cursor is on thefolder icon602, holds pressed theenter key33 of theremote control31 for a certain period of time or longer. Then, thedeletion control unit27 deletes thefolder icon602 and all the icons included in thefolder icon602 from thepage image204 and the in-folder-icon image403.

It is noted that if the operation signal from theremote control31 to the receivingunit28 is the operation signal transmitted when the user presses a key other than theenter key33 or the directional key32 (S20: NO), executed is a process associated with a key which the user has pressed (S22). For example, if the user presses a TV program listing key of theremote control31, the icon editing task is canceled and the screen displays a TV program listing.

[1-3. Effects Etc.]

As described above, in the embodiment, multiple page images and an in-folder-icon image are displayed on the screen. Such a feature makes it possible to display icons in different hierarchies on the same screen. Hence, the user can efficiently carry out an icon editing task.

In addition, the user can make a folder icon by simply operating a directional key to move a cursor to an icon display area with no icon displayed and pressing an enter key. Hence, the user can efficiently carry out an icon editing task using an input apparatus such as a remote control equipped with limited keys.

Furthermore, when the user selects an icon included in the icon list image, the folder icon including the selected icon is highlighted. Hence, the user can easily find out that the icon is included in which folder icon on which page image. Especially, in the case where a folder icon is not displayed on the screen of thedisplay unit30, such a feature saves the user the trouble of looking for the folder icon.

In addition, the user can switch the display positions of two icons through a simple operation to successively select the two icons. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

In addition, the user can move an icon through a simple operation to select an icon and then an empty area. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

Furthermore, the user can delete a folder icon by operating a directional key to move a cursor to the folder icon and then holding an enter key pressed. Hence, the user can efficiently delete a folder icon using an input apparatus such as a remote control equipped with limited keys.

The art is applicable to another embodiment—that is the embodiment with appropriate change, replacement, addition, and omission made thereto. A new embodiment may also be implemented by a combination of each of the constituent elements described in the embodiment.

Exemplified below are other embodiments.

When the in-folder-icon image403 is displayed as represented inFIG. 12, for example, suppose the user operates thedirectional key32 of theremote control31 to move a cursor to an icon in the page image, and, while the cursor is on the icon, holds pressed theenter key33 of theremote control31 for a certain period of time or longer. When the icon is the selectedicon604, theremote control31 transmits an operation signal indicating an operation which keeps selecting the selectedicon604 for a certain period of time or longer. When the receivingunit28 receives the operation signal, theposition changing unit26 may move the selectedicon604 to anicon display area410 in the in-folder-icon image403. Such features make it possible for the user to efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

As represented inFIG. 12, suppose the user operates thedirectional key32 of theremote control31 to move a cursor to theicon404 in the in-folder-icon image403, and, while the cursor is on theicon404, holds pressed theenter key33 of theremote control31 for a certain period of time or longer. Theremote control31 transmits an operation signal indicating an operation which keeps selecting theicon404 for a certain period of time or longer. When the receivingunit28 receives the operation signal, theposition changing unit26 may move theicon404 to an icon display area (for example, the icon display area603) found on any given page image and displaying no icon. Hence, the user can efficiently change the display position of an icon using an input apparatus such as a remote control equipped with limited keys.

In the above description, examples of the operation that holds pressed theenter key33 for a certain period of time or longer may include an operation which double-taps theenter key33.

In addition, a folder icon may include another folder icon. Here, when the user selects a folder icon in the in-folder-icon image403, for example, the seconddisplay control unit23 further displays on the screen another in-folder-icon image403 for displaying an icon included in the selected folder icon. In other words, two in-folder-icon images403 may be displayed on the screen. Such a feature allows the user to switch the display positions of icons and move an icon over three or more hierarchies.

When icons significantly increase in number, the user has to press the directional key32 very frequently to move a cursor to a desired icon, which could be greatly troublesome to the user. Hence, the imagedisplay control device20 may predict an icon to be chosen next as soon as the imagedisplay control device20 changes to the swap mode, scroll and display a page image or an in-folder-icon image, and automatically move a cursor to the predicted icon. If the prediction is right, such a feature allows the user to switch positions of icons by simply pressing theenter key33 of theremote control31. For example, as soon as a game-related icon in the in-folder-icon image is selected, the imagedisplay control device20 may move the cursor to an icon of any given game in the page image including the most game-related icons. Such a feature contributes to eliminating troubles relating to scrolling by the user if the prediction is right.

Moreover, theposition changing unit26 may automatically rearrange icons based on the attributes of icons. For example, theposition changing unit26 may automatically rearrange icons as much as possible so that game-related icons are placed on the same page or pages close to each other.

In the above embodiment, the imagedisplay control device20 may include, but not be limited to, one of the following application-executable devices: a recording appliance such as a hard-disk drive recorder, a TV, and a personal digital assistance. For example, the imagedisplay control device20 may be one of the following devices that are capable of reproducing content such as recorded video: a recording appliance such as a hard-disk drive recorder, a TV, and a personal digital assistance. Here, each of the icons is associated with a corresponding one of content files.

In the above embodiment, an exemplary icon displayed on the screen of thedisplay unit30 indicates a downloaded application; instead, the exemplary icon may indicate an application previously stored in the imagedisplay control device20.

Specifically, the imagedisplay control device20 may be a computer system including a microprocessor, a ROM, a RAM, a hard disk drive, a display unit, a keyboard, a mouse. The RAM or hard disk drive stores a computer program. The imagedisplay control device20 achieves its functions through the microprocessor's operation according to the computer program. Here, the computer program is configured by combining instruction codes indicating instructions to the computer.

The System-LSI is a super-multi-function LSI manufactured by integrating constituent units on one chip. Specifically, the System-LSI is a computer system including a microprocessor, a ROM, and a RAM. The RAM stores a computer program. The System-LSI performs its functions through the microprocessor's operation according to the computer program.

A part or all of the constituent elements included in the imagedisplay control device20 may be configured as an IC card which can be attached to and detached from the imagedisplay control device20 or as a stand-alone module. The IC card or the module is a computer system configured from a microprocessor, a ROM, and a RAM. The IC card or the module achieves its function through the microprocessor's operation according to the computer program. The IC card or the module achieves its function through the microprocessor's operation according to the computer program. The IC card or the module may also be tamper-resistant.
