A display image outputted by first image processing for expanding or reducing the contents with the display magnification is displayed, and if the display magnification exceeds a range of a first threshold, a display image outputted by second image processing from the contents is displayed.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a content display device that displays content on a display screen integrated with a touch panel.

  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, the contents are pointed with two fingers, and the distance between the fingers is changed (pinch-in / pinch-out) to reduce / enlarge, making it suitable for the user to view on a large screen. Gesture operations that can be compared by size are known (for example, see Patent Document 1).

  Usually, the operation amount of the pinch-in / pinch-out is detected, and the display magnification is changed according to the operation amount. Since the size of the operator's hand is limited, if a similar operation is performed again within a predetermined time after the pinch-in operation is finished (touch state is released), You may judge.

  Also, like Microsoft's Windows (registered trademark), etc., a minimize button is provided to temporarily evacuate the content without erasing it from the screen, and it can be moved to a specific position on the screen by pressing the minimize button. A product having a function of displaying in the form of an icon image indicating the type of content is known.

JP 2013-206317 A

  However, in the conventional method, when the user performs the minimization, the user becomes an icon indicating the type of content, and thus the content cannot be confirmed. For example, Windows has a function of confirming contents by matching a mouse pointer to an icon on a task bar, but a mouse moving operation is necessary for confirming the contents.

  In addition, a reduction operation can be performed instead of an icon operation so that the contents can be visually recognized. However, even when the content is displayed in a reduced size, the title bar and the menu displayed on the title bar have the same size as usual, so there is a problem that the visibility is poor.

  In addition, when a plurality of contents are reduced, each reduction size depends on the finger interval when the pinch-in is released, and thus it is difficult to reduce the same size. Also, since the display position also depends on the position when the pinch-in is released, an alignment operation is separately required when handling a plurality of contents.

  Further, as described above, the reduced display and the iconization operation are different operation systems. When sorting while comparing normal contents, the size of one content is slightly reduced, the next content is evacuated, the next content is kept slightly larger, etc. In many cases, reduction and evacuation are performed, and the fact that these operations are separate systems is not a desirable operation method in consideration of the entire operation system for content selection.

  In view of the above-described problems, the present invention firstly performs an operation for reduction and an operation for retraction within the same operation system, and secondly, when an operation such as enlargement / reduction of content is performed, it is visually recognized by the operator. It is to provide a content display device and the like that are highly versatile and easy to use.

In view of the above-described problems, the content display device of the present invention is
In a content display device capable of displaying one or more contents on a display screen,
Operation detecting means for detecting an enlargement operation or a reduction operation for the displayed content;
Display means for determining a display magnification based on an operation amount of the enlargement operation or the reduction operation, and displaying an enlarged or reduced content whose operation is detected at the determined display magnification;
With
The display means displays a first identification display on the content for which the reduction operation has been detected when the display magnification is equal to or less than a preset first threshold, and when the reduction operation is no longer detected, Content in which a reduction operation is detected is displayed in a specific area of the display screen in place of a reduced image of a predetermined size.

The content display method of the present invention is a content display method in a content display device capable of displaying one or more contents on a display screen,
An operation detecting step for detecting an enlargement operation or a reduction operation for the displayed content;
A display step of determining a display magnification based on an operation amount of the enlargement operation or the reduction operation, and displaying an enlarged or reduced content whose operation is detected at the determined display magnification; and
Including
The display step displays a first identification display on the content for which the reduction operation is detected when the display magnification is equal to or less than a preset first threshold, and when the reduction operation is no longer detected, Content in which a reduction operation is detected is displayed in a specific area of the display screen in place of a reduced image of a predetermined size.

The program of the present invention
To a computer that can display one or more contents on the display screen,
An operation detection function for detecting an enlargement operation or a reduction operation for the displayed content;
A display function for determining a display magnification based on an operation amount of the enlargement operation or the reduction operation, and displaying an enlarged or reduced content in which the operation is detected with the determined display magnification;
Is a program for realizing

  When the display image based on the content is displayed based on the display magnification designated by the first operation, and the display magnification exceeds the predetermined threshold range by the first operation, the second image processing is performed. The output display image is displayed. That is, as an operator, despite the same first operation, a display image that has been subjected to different image processing depending on the display magnification is displayed.

  Therefore, an appropriate display image is displayed without the operator performing a special operation or being conscious of it, and a content display device with improved usability can be provided.

  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 content display apparatus 10 that can be operated by a touch panel to which the content display apparatus 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 content 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.

[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 stores various contents as a data file 162. This content may be, for example, 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.

  Further, the storage unit 160 has a flag storage area 164 for storing a flag and a threshold storage area 166 for storing a threshold. The flags and threshold values stored in these areas will be described in the embodiments described later.

  The process management information 168 is information for managing the process being executed. Here, the display screen (display area) in this embodiment is managed by a process. The operation window that can be displayed by the process may be one or two or more.

  An example of the process management information 168 is shown in FIG. The process management information 168 in this embodiment includes a process ID (for example, “PID 201”) for identifying each process, a state (for example, “Active”), and a display area (for example, “(200, 150) − (400, 500) ") is managed.

  As the process state, “Active” which is currently operable (displayed), “min1” which indicates a special reduced display in an identifiable state, and an icon state which is reduced in an icon state are displayed. States such as “min2” and “sleep” where the process is paused are shown.

[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 a reduction operation is performed (step S104). Here, the reduction operation in the present embodiment is a case where pinch-in is detected on a target display area (window).

  When a reduction operation is detected (step S104; Yes), the size (operation start size, position) of the display image (window) at the start of the operation is stored (step S106). Specifically, the process management information display area is updated.

  Subsequently, an image resizing process is executed (step S108). Here, the image resizing process is a process for reducing or enlarging the display image by an operator's pinch-in / pinch-out process. Specifically, a display image to be displayed on the display unit 120 is generated from the content read from the data file 162 and output. At this time, as the first image processing, content simply enlarged or reduced based on the display magnification is output as a display image.

  A reduced window (enlarged window) is displayed as needed. In the present embodiment, a description will be given on the assumption that reduced display (pinch-in operation) is performed.

  In the present embodiment, the window itself is described as being reduced (enlarged). However, for example, the outer frame of the window is displayed and the size of the area is displayed (that is, the content in the window is not displayed). It may be.

  Here, when the display size (window size) of the reduced display image is equal to or smaller than the reduction threshold (step S110; Yes), it is confirmed whether or not the special reduction flag (special reduction F) is “ON”. (Step S112).

  In other words, it is determined whether or not the display magnification exceeds a predetermined range (here, the reduction ratio is equal to or less than the reduction threshold and thus exceeds the appropriate display magnification).

  The reduction threshold is a value stored in the threshold storage area 166. In other words, when the size of the operated window is equal to or smaller than the reduction threshold value, special reduction display described later is performed.

  As an example of the reduction threshold, for example, a threshold for switching to the special reduction display is stored in advance when the diagonal line is 200 dots or less, or when one side is 150 dots or less. Note that the user may set an arbitrary value for the reduction threshold. Further, this value is not a specified numerical value, but may be set by a ratio when the size becomes 1/10 of the entire screen.

  The special reduction flag is a flag for determining whether or not special reduction display has already been performed. The special reduction flag is stored in the flag storage area 164. For example, if it is “ON”, it indicates that the window has already been subjected to special reduction display.

  When the special reduction F is “OFF”, the special reduction F is set to “ON” and identification display is performed for the window (Step S112; No → Step S114 → Step S116). Here, for the identification display, for example, the outer frame of the content (window) may be a thick line, the color may be changed, or a blinking display may be performed. Further, it may be notified by displaying “special reduction display” in another area, or may be notified by LED or sound.

  If it is larger than the reduction threshold value in step S110 (step S110; No), if special reduction F is ON in step S112 (step S112; Yes), or after the identification display is performed (step S116), is multi-touch canceled? It is determined whether or not (step S118).

  If the multi-touch is not released, the process is repeatedly executed from step S108 (step S118; No → step S108), and if the multi-touch is released, it is determined whether the special reduction F is “ON” or “OFF”. (Step S118; Yes → Step S120).

  If the special reduction F is “OFF”, the window contents are updated and displayed with the window display size when the multi-touch is released (step S120; No → step S124). At this time, the display area of the process management information 168 is updated.

  If the special reduction F is “ON”, the special reduction display process is executed (step S120; Yes → step S122).

  Here, the special reduction display processing will be described with reference to FIG. First, the operation start size (position) is stored (step S152). That is, the display area and size at the start of the operation are stored.

  In the case of the present embodiment, the processing is realized by not updating the process management information display area. Note that the position and size of the window at the start of the operation may be stored separately.

  Subsequently, a special reduced image is generated (step S154), and the generated special reduced image is aligned and displayed (step S156).

  Here, the generation of the special reduced image will be described with reference to FIG. FIG. 6A shows a window L100 displayed on the display screen. The image displayed in the window L100 is an image that is extracted from the content and displayed. In the case of content itself or content composed of a plurality of pages, for example, it may be an image of the currently displayed page.

  As shown in FIG. 6B, the L100 includes a layer L110 and a layer L120. That is, a layer L110 that can be simply reduced and enlarged, such as figures and graphs, and a layer L120 that does not simply reduce or enlarge because characters, operation icons, marks, and the like are described.

  In the case of a special reduced image, the layer L110 is simply reduced, but the layer L120 is reduced and displayed by a different method. Specifically, a process of reducing the reduction rate compared to the layer L110, a process of reducing only the font size to the minimum size, and the like are performed.

  In this case, when characters such as a title no longer enter, a special reduced image is generated by omitting a part or changing the layout. The special reduced image generated in this way is shown in FIG.

  Compared with the general reduced image shown in FIG. 6D, all of which are reduced at the same display magnification, the character portion is displayed larger. Therefore, even if the display is reduced, characters and the like can be visually recognized, and a user-operable content display device can be provided.

  Here, the above-described processing is performed in order to make it easy to visually recognize the text portion of the special reduced image, but of course, the special reduction is applied to FIG. It may be used as an image, or an image generated in advance may be used as a special reduced image

  When a special reduced image is displayed, it may be displayed in a state where it can be identified. For example, in the case of normal display (in the case of a normal window or simply reduced display), the title bar includes a title, a delete button, a content type, a priority, a color display for distinguishing the favorite state, and the like. However, in special reduced display, color display and only a few characters of the title (for example, the first five characters) may be displayed.

  Also, the title may be displayed when the operator touches with a finger or a pen or touches the vicinity without displaying the title on the special reduced image.

[1.4 Operation example]
Subsequently, an operation example in the present embodiment will be described with reference to the drawings. FIG. 7 shows a state where a window R100 is displayed on the display screen W100. In this state, when the operator performs a pinch-in operation on the display area of the window R100, the display image (window) is reduced and displayed. FIG. 8 shows a reduced display state.

  At this time, when the operator P stops the pinch-in operation and cancels the touch state, the reduced display stops at the size of the window R110. At this time, it is a general reduction display, and all the characters and figures displayed in the window R110 are reduced and displayed at the same magnification.

  If the pinch-in operation is continued from the state of FIG. 8, the state transitions to the state of FIG. That is, when the operator P continues to perform the pinch-in operation, the identification display is performed on the window R120. This indicates that the process of performing reduced display has shifted to the process of performing special reduced display.

  In this state, when the operator P stops the pinch-in operation and cancels the touch state, the special window is displayed in a special reduced size. Then, it is displayed on R130 as a special reduced display on the display screen W100.

  Here, the special reduced display is displayed side by side. As a result, the special reduced display is displayed in a list with good visibility for the operator. Note that the images may be displayed in a special reduced size on the spot without being arranged.

[2. Second Embodiment]
Next, the second embodiment will be described. In the first embodiment, the case where the reduced display (pinch-in operation) is performed has been described for convenience of explanation, but in this embodiment, the case where the pinch-out operation is performed in the middle will also be described.

  In the second embodiment, the configuration and functional configuration of the apparatus are the same as those of the first embodiment, and thus the description thereof will be omitted and the flow of processing will be described. Further, in the processing flow, the same processes as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  First, when multi-touch is detected (step S202; Yes), it is determined whether or not a pinch operation has been performed (step S204). Here, when a pinch operation is detected, the operation start size disclosed for the pinch operation is stored (step S206).

  Subsequently, a display image resizing process is executed in accordance with the pinch operation (step S208). That is, if it is a pinch-in operation, a reduction process is executed, and if it is a pinch-out operation, an enlargement process is executed.

  If the display size of the current display image is equal to or smaller than the reduction threshold, it is checked whether or not the special reduction flag (F) is “ON” (step S210; Yes → step S212). If the special reduction F is not yet “ON”, the special reduction F is turned “ON” and identification display is performed (step S212; No → Step S214 → Step S216).

  In step S210, when the current display image (window size) becomes larger than the reduction threshold (step S210; No), the special reduction F is set to “OFF” and the identification display is released (step S218 → step). S220).

  When multi-touch is released (step S222; Yes), processing is executed according to the special reduction F (steps S120 to S124).

  As described above, according to the present embodiment, when the display image based on the content is reduced by the pinch-in operation and becomes equal to or smaller than the reduction threshold, the general reduction display processing is switched to the special reduction display processing. When the content is enlarged by the focus-out operation, the special reduction display processing operation is canceled.

[3. Third Embodiment]
Subsequently, the third embodiment will be described. In the third embodiment, a case where a plurality of special reduced display processes can be performed will be described.

  That is, the three operation modes can be switched based on the pinch-in operation and the pinch-out operation.

  Specifically, a plurality of pieces of information regarding the threshold storage area 166 and the process management information 168 are stored. In the case of this embodiment, two cases will be described.

  FIG. 12 is an operation flow for explaining the processing of the third embodiment. This figure is the same processing up to step S206 of the second embodiment, and the subsequent processing is described.

  First, image resizing processing is executed according to the operator's pinch-in and pinch-out processing (step S302). Here, the processing is changed depending on whether the display size (window size) of the display image is equal to or smaller than the second reduction threshold, the range from the second reduction threshold to the first reduction threshold, or a value larger than the first reduction threshold.

  That is, when the value is equal to or smaller than the second reduction threshold, the special reduction F is set to “2” and the second identification display is executed (Step S304; Yes → Step S306; Yes → Step S312 → Step S314).

  If it is greater than the second reduction threshold and less than or equal to the first threshold, “1” is set in the special reduction F and the first identification display is executed (step S304; Yes → Step S306; No → Step S308 → Step S310).

  If it is larger than the first reduction threshold, the special reduction F is set to “0”, and the identification display is canceled (Step S304; No → Step S316 → Step S318). As a result, processing corresponding to the current window size is performed, and further, what kind of processing is performed is understood by performing identification display to the operator.

  That is, after the multi-touch is released (step S320; Yes), if the special reduction F is “1”, the first special reduction process is executed (step S322; No → Step S324; Yes → Step S326), If the special reduction F is “2”, the second special reduction process is executed (step S322; No → Step S324; No → Step S328).

  Here, the first special reduction process and the second special reduction process perform a plurality of different processes. As an example, for example, a reduction process such as a thumbnail is executed as the first special reduction process, and a reduction process such as iconification is executed as the second special reduction process.

  If the special reduction F is “OFF”, the display image is updated with the reduced display image size, that is, the display is continued with the size of the currently displayed window, and the process management information 168 is updated. (Step S330).

  Subsequently, an operation example of the present embodiment will be described with reference to FIG. In FIG. 13A, a normal window (content) is displayed. Here, the window (contents) shown in FIG. 13B is reduced and displayed. Here, the display image of the normal content is reduced and displayed. FIG. 13C shows a state where the content is iconified.

  As described above, according to the present embodiment, a plurality of image processes can be switched and executed by the same operation (pinch operation).

[4. Fourth Embodiment]
Next, a fourth embodiment will be described. The fourth embodiment is an embodiment for explaining that different operations can be executed not by special reduced display processing but by list display processing.

  Here, the operation flow of the fourth embodiment is shown in FIG. The operation flow in FIG. 14 is the same processing up to step S206 in the operation flow of the second embodiment shown in FIG. 11, and the processing from step S208 is replaced with step S402.

  First, after the image resizing process is performed (step S402), it is determined whether or not the current display image size is equal to or smaller than a reduction threshold (step S404). If the display image size is equal to or smaller than the reduction threshold (step S404; Yes), if the list display flag (F) is not “ON”, the list display F is set to “ON” and identification display is performed (step S406; No). → Step S408 → Step S410).

  On the other hand, if the current display image size is larger than the reduction threshold in step S404 (step S404; No), the list display F is set to “OFF” and the identification display is canceled (step S414).

  Here, when the multi-touch by the operator is released (step S416; Yes), it is determined whether or not the list display F is “ON” (step S418). Here, if the list display F is “ON”, a list display process is executed (step S418; Yes → step S420).

  On the other hand, if the list display F is “OFF”, the display image is updated with the reduced display image size, that is, the display is continued with the size of the currently displayed window, and the process management information 168 is updated. (Step S422).

  An example of operation in the present embodiment is shown in FIGS. In the display screen W400 of FIG. 15, the operator P is performing a pinch-in operation. Since the window R400 is equal to or smaller than the reduction threshold, the identification display is performed.

  FIG. 16 shows a state where the pinch-in is released in the state shown in FIG. As shown in FIG. 16, a window group R410 is displayed. Thus, a list display is realized by displaying a plurality of windows.

  Thus, according to this embodiment, it is possible to execute various processes by the same operation by executing the processes. For example, as in the present embodiment, not only the special reduced display process but also a process such as a list display process can be executed.

[5. Fifth Embodiment]
Subsequently, a fifth embodiment will be described. The fifth embodiment is an embodiment in which a display image is enlarged by a pinch-out operation.

  FIG. 17 shows an operation flow of a processing flow in the fifth embodiment. First, when multi-touch is detected (step S502; Yes) and a pinch operation is detected (step S504; Yes), an operation start size is stored (step S506).

  Here, an image resizing operation is executed according to the pinch operation (step S508). For example, in the case of this embodiment, by performing a pinch-out operation, the display magnification is increased and the display image is enlarged and displayed. In the case of a pinch-in operation, any one of the above-described embodiments is executed.

  If the size of the enlarged display image is equal to or larger than the enlargement threshold (step S510; Yes), it is determined whether or not the full screen display F is already “ON” (step S512). If the full screen display F is not yet “ON”, the full screen display F is set to “ON” and identification display is performed (step S521; No → Step S514 → Step S516).

  If the size of the display image is smaller than the enlargement threshold (step S510; No), the full screen display F is set to “OFF” and the identification display is canceled (step S518 → step S520).

  Here, when the multi-touch by the operator is released (step S522; Yes), it is determined whether or not the full screen display F is “ON” (step S524). When the full screen display F is “ON”, the display image is displayed on the full screen (step S526).

  On the other hand, if the full-screen display F is “OFF”, the display image is updated with the enlarged image size, that is, the display is continued with the size of the currently displayed window, and the process management information 168 is updated. (Step S528).

  Examples of operations in this embodiment are shown in FIGS. In the display screen W500 of FIG. 18, the operator P is performing a pinch-out operation. Since the window R500 is equal to or larger than the enlargement threshold value, the identification display is performed.

  FIG. 19 shows a state where the pinch out is released in the state shown in FIG. 18 (a state where multi-touch is released). As shown in FIG. 19, a full screen is displayed as a window R510.

  Thus, according to the present embodiment, various processes can be executed by the same operation even in the enlargement process of pinch out. For example, as in the present embodiment, when an enlarged display is performed, it is possible to automatically perform a full screen display with a certain size.

[6. Sixth Embodiment]
Subsequently, a sixth embodiment will be described. In the sixth embodiment, a case where a process is canceled by performing another operation while performing an operation will be described. The operation flow of this embodiment is shown in FIG. The operation flow in FIG. 20 is processing in which steps S508 to S522 are replaced in the operation flow in FIG. In addition, parts having the same operation float process in FIG.

  It is detected whether or not the display image size (window size) is equal to or larger than the enlargement threshold value and a rotation operation has been performed in the state of being identified and displayed.

  That is, when the image rotation operation is performed by the operator and the display image is in the rotation state, the full screen display F is set to “OFF” and the identification display is canceled (step S602; Yes → Step S604 → Step S606). ).

  As a result, it is possible to perform processing such as performing an enlargement operation but not performing full-screen display. FIG. 21 shows an example of the operation at this time. As shown in FIG. 21, when the operator P performs a rotation operation, the identification display is subsequently released, and the full screen display is not performed. In FIG. 21, when the rotation operation is performed, the window R600 itself also makes the operator visually recognize that the rotation operation has been performed by rotating the display, but without changing the display of the window R600, The operator may visually recognize the icon by displaying an icon indicating that the full screen display is not performed.

  As described above, according to the present embodiment, it is possible to cancel the current processing by performing the rotation operation during the pinch-out operation.

  In this case, it is possible to use the current enlarged display image without simply performing full-screen display, or to return the display image to the initial value.

  Further, in the present embodiment, the pinch-out operation has been described, but the same can be realized in the pinch-in operation.

  In the present embodiment, the rotation operation has been described as an example, but an operation different from the current operation may be performed. For example, it may be another operation such as a swipe operation or a flick operation, or may newly detect a touch of three or more points.

[7. Seventh Embodiment]
Next, a seventh embodiment will be described. The seventh embodiment describes an embodiment in which the pinch-out operation is continued, and after the processing shifts to the full screen display, the pinch-out operation is further continued to shift to the enlargement process again. The operation flow of this embodiment is shown in FIG. The operation flow in FIG. 22 is processing in which step S508 to step S522 are replaced in the operation flow in FIG.

  After the image resizing process is executed (step S702), it is determined whether or not the current display image size (window size) is greater than or equal to the first threshold value. Here, if it is equal to or greater than the first threshold, if the full screen display F is not yet “ON”, the full screen display F is set to “ON” and identification display is performed (step S704; Yes → Step S706; No → Step). S708; No-> Step S710-> Step S712).

  However, if it is equal to or greater than the first threshold but is further equal to or greater than the second threshold due to further enlargement operation (pinch-out operation), the full screen display F becomes “OFF” and the identification display is It is canceled (Step S704; Yes → Step S706; Yes → Step S714 → Step S716).

  When the multi-touch process is canceled (step S718; Yes), the display image is enlarged or displayed in full screen according to the current state of the full screen display F. That is, when there is a display image size between the first threshold value and the second threshold value, the entire screen is displayed, but when it exceeds the second threshold value, it is enlarged and displayed as it is.

  FIG. 23 is a diagram illustrating an operation example in the seventh embodiment. FIG. 19 is a diagram showing a further enlargement operation from the state of FIG. 18. As described above, in the display screen W700, a part of the window R500 in FIG.

  As described above, in the present embodiment, a plurality of processes can be switched even in the same operation, and the same operation can be realized again. In particular, in the case of an enlargement operation, there is a need to enlarge and display a part, and this is an effective embodiment.
