JP6720387B2 - Content display device, content display method, and program - Google Patents

Description

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

2. Description of the Related Art In recent years, a large screen has been developed in various devices such as computers and AV devices that display content. Up to now, most of the operations on the small and medium screens have been done by displaying at most a few windows, but it is now possible to display a large screen and expand the application to display many contents at once. There is.

In order to handle a large number of contents, for example, by pointing the contents with two fingers and changing the distance between the fingers (pinch in/pinch out), the contents are reduced/enlarged, making it suitable for users to view on a large screen. Gesture operations that can be compared in size are known (for example, see Patent Document 1).

Usually, the operation amount of pinch-in/pinch-out is detected, and the display magnification is changed according to the operation amount. Since there is a limit to the size of the operator's hand, if the same operation is performed again within a predetermined time after the pinch-in operation is finished (the touch state is released), it will be regarded as a continuous operation. You may judge.

Also, like Windows (registered trademark) of Microsoft Corporation, a minimize button is provided to temporarily save the contents without erasing the contents from the screen, and by pressing the minimize button, the minimize button is clicked to a specific position on the screen. A product having a function of displaying in the form of an icon image showing the type of content is known.

JP, 2013-206317, A

However, in the conventional method, when the user minimizes the icon, it becomes an icon indicating the type of the content, so that the user cannot confirm the content of the content. For example, Windows has a function of confirming the contents by placing the mouse pointer on the icon on the taskbar, but a mouse movement operation is required to confirm the contents.

Further, it is possible to perform a reduction operation 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 therein have the same size as in the normal state, and thus there is a problem in that the visibility is poor.

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

Further, as described above, the reduced display and the iconized operation have different operation systems. When selecting while comparing normal content, reduce the size of a certain content a little, save the next content, leave the next content a little larger, and so on. Since reduction and evacuation are often performed, the fact that these operations are separate systems is not a desirable operation method considering the overall operation system for content selection.

In view of the above-mentioned problems, the present invention firstly performs an operation for reducing and an operation for saving in the same operation system, and secondly, when performing an operation such as enlarging/reducing content, the operator visually recognizes it. The purpose of the present invention is to provide a content display device and the like that is highly versatile and easy to use.

In view of the above-mentioned problems, the content display device of the present invention is

When the display image based on the content is displayed based on the display magnification specified 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 the operator, the display image that has been subjected to different image processing depending on the display magnification is displayed despite performing the same first operation.

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

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. Note that, for convenience of description, the embodiment will be described as an example, but it goes without saying that any device can be applied as long as the device can perform display operation.

[1. First Embodiment]
[1.1 Overall configuration]
FIG. 1 is a diagram showing an appearance of a content 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 the touch panel and is operable by the operator.

Here, the content display device 10 can be operated by a plurality of operators depending on the size and shape of the display unit. For example, it is possible to use it for face-to-face business meetings and various meetings by operating from four directions.

[1.2 Functional configuration]
Subsequently, 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 realizes 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) or the like.

The display unit 120 is a functional unit for displaying various information. For example, it is composed of 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, 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 by the operator. Further, it is possible to detect a plurality of inputs from the operator. For example, 5 points at the same time or 10 points at the same time.

Further, when the detection range is within a 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 that expands content read from a file or the like, outputs a display image, and performs image processing such as filtering on the image. Here, description of conventional image processing (for example, extracting an image to be displayed from content, and simply enlarging/reducing display image) is omitted.

The communication unit 150 is a network interface unit for connecting to an external network of the Internet or another device. 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 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

Further, 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 files that can be displayed on the display unit 120, such as PDF, document files, and presentation files.

Further, in the storage unit 160, a flag storage area 164 for storing a flag and a threshold storage area 166 for storing a threshold are secured. Flags and threshold values stored in these areas will be described in an embodiment 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 number of operation windows that can be displayed by a process may be one or may be two or more.

Here, 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, “PID201”) for identifying each process, a state (for example, “Active”), and a display area (for example, “(200,150)- (400,500)”) are managed.

As the process state, the currently operable (displayed) "Active", the special reduced display which is reduced and displayed in the identifiable state "min1", and the icon state which is reduced and displayed in the icon state are shown. States such as "min2", "sleep" in which the process is paused, etc. 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 the operation is a reduction operation (step S104). Here, the reduction operation in the present embodiment is a case where a pinch-in is detected in the target display area (window).

When the 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 display area of the process management information is updated.

Subsequently, the image resizing process is executed (step S108). Here, the image resizing process is a process of reducing or enlarging the display image by the pinch-in and pinch-out processes of the operator. Specifically, the display image displayed on the display unit 120 is generated by the image processing unit 140 from the content read from the data file 162, and is output. At this time, as the first image processing, the content that has been simply enlarged or reduced based on the display magnification is output as a display image.

Then, the reduced window (enlarged window) is displayed at any time. In the present embodiment, description will be made assuming that reduced display (pinch-in operation) is performed.

In the present embodiment, the window itself is described as being reduced (enlarged), but for example, the outer frame of the window is displayed to indicate the size of the area (that is, the content in the window is not displayed). May be

Here, when the display size (window size) of the reduced display image is equal to or smaller than the reduction threshold value (step S110; Yes), it is confirmed whether the special reduction flag (special reduction F) is “ON”. (Step S112).

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

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

As an example of the reduction threshold value, for example, a threshold value for switching to the special reduction display is stored in advance such as when the diagonal line is 200 dots or less or when one side is 150 dots or less. The reduction threshold may be set by the user to any value. Further, this value is not a specified numerical value, and 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 the special reduction display has already been performed. The special reduction flag is stored in the flag storage area 164, and if it is “ON”, it indicates that the window is already in special reduction display.

When the special reduction F is "OFF", the special reduction F is turned "ON" and the window is displayed in an identifiable manner (step S112; No→step S114→step S116). Here, for the identification display, for example, the outer frame of the content (window) may be a bold line, the color may be changed, or blinking display may be performed. Further, it may be notified by displaying "special reduced 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 the special reduction F is ON in step S112 (step S112; Yes) or after the identification display is performed (step S116), the multi-touch is released. 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).

Here, when the special reduction F is “OFF”, the window contents are updated and displayed with the display size of the window 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 reduced display processing will be described with reference to FIG. First, the operation start size (position) is stored (step S152). That is, the display area, size, etc. at the start of the operation are stored.

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

Then, a special reduced image is generated (step S154), and the generated special reduced images are arranged 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 the image extracted from the content and displayed. It may be the content itself, or, for example, in the case of content consisting of a plurality of pages, it may be an image of the currently displayed page.

As shown in FIG. 6B, this L100 is composed of a layer L110 and a layer L120. That is, it is composed of a layer L110 that may be simply reduced or enlarged such as a drawing and a graph, and a layer L120 that is not simply reduced or enlarged because characters, operation icons, marks and the like are described.

In the case of the 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 ratio as compared with the layer L110, a process of reducing the font size to the minimum size, and the like are performed.

In this case, when characters such as a title cannot be entered, the special reduced image is generated by partially omitting it or changing the layout. The special reduced image generated in this way is shown in FIG.

Compared to the general reduced image shown in FIG. 6D in which all are reduced at the same display magnification, the character portion is displayed in a large size. Therefore, the characters and the like can be visually recognized even in the reduced display, and it is possible to provide the user (operator) with a content display device which is easy to use.

Here, the above-described processing is performed to make it easier to visually recognize the text portion of the special reduced image. However, of course, the special reduction of FIG. You can use it as an image, or you can use a pre-generated image as a special reduced image.

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

Further, the title may not be displayed on the special reduced image, and the title may be displayed when the operator touches with a finger or a pen or touches the vicinity.

[1.4 Operation example]
Next, an operation example of this embodiment will be described with reference to the drawings. FIG. 7 shows a state in which the 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 state in which the display is reduced.

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

When 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 continuously performs the pinch-in operation, the identification display is performed on the window R120. This indicates that the process for performing the reduced display has transitioned to the process for performing the special reduced display.

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

Here, the special reduced display will be displayed side by side. As a result, the special reduced display is displayed in a list with good visibility for the operator. It should be noted that the special reduction display may be performed on the spot without being arranged according to the setting.

[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 is described for convenience of explanation, but in the present embodiment, the case where the pinch-out operation is in the middle will be described.

Since the second embodiment has the same device configuration and functional configuration as those of the first embodiment, a description thereof will be omitted, and a processing flow will be described. Further, in the process flow, the same processes as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

First, when multi-touch is detected (step S202; Yes), it is determined whether a pinch operation has been performed (step S204). If a pinch operation is detected, the operation start size disclosed in the pinch operation is stored (step S206).

Then, the resizing process of the display image is executed according to the pinch operation (step S208). That is, a pinch-in operation executes a reduction process, and a pinch-out operation executes an enlargement process.

Then, when the display size of the current display image is equal to or smaller than the reduction threshold, it is confirmed whether or not the special reduction flag (F) is "ON" (step S210; Yes→step S212). Here, if the special reduction F is not "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 turned off and the identification display is canceled (step S218→step). S220).

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

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

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

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 are stored in the threshold value storage area 166 and the process management information 168. In the case of this embodiment, two cases will be described.

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

First, image resizing processing is executed according to the operator's pinch-in and pinch-out processing (step S302). Here, the process 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 of the second reduction threshold to the first reduction threshold, or a value larger than the first reduction threshold.

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

If it is larger than the second reduction threshold and equal to or smaller than the first threshold, the special reduction F is set to "1" 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 value, the special reduction F is set to "0" to cancel the identification display (step S304; No→step S316→step S318). As a result, processing is performed according to the current window size, and by performing identification display for the operator, it becomes possible to understand what processing is to be performed.

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 processing and the second special reduction processing perform a plurality of different processes. As an example, a thumbnail-like reduction process is performed as the first special reduction process, and an icon reduction process is performed 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).

Next, an operation example of this embodiment will be described with reference to FIG. In FIG. 13A, a normal window (content) is displayed. Here, the window (content) shown in FIG. 13B is reduced and displayed. Here, the display image of the normal content is reduced and displayed. And FIG.13(c) has shown the state by which the content was iconified.

As described above, according to the present embodiment, it is possible to switch and execute a plurality of image processes by the same operation (pinch operation).

[4. Fourth Embodiment]
Subsequently, a fourth embodiment will be described. The fourth embodiment is an embodiment for explaining that as a different operation, not only the special reduced display processing but also the list display processing can be executed.

Here, the operation flow of the fourth embodiment is shown in FIG. The operation flow of FIG. 14 is the same processing up to step S206 of 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 the current display image size is equal to or smaller than the reduction threshold (step S404). If the display image size is less than or equal to the reduction threshold value (step S404; Yes), 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 value 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 the list display F is "ON" (step S418). If the list display F is “ON”, the 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 window currently displayed and the process management information 168 is updated. (Step S422).

An operation example in this embodiment is shown in FIGS. It is a figure in which the operator P is performing the pinch-in operation on the display screen W400 of FIG. Since the window R400 has become equal to or smaller than the reduction threshold, the identification display is performed.

The state in which the pinch-in is released in the state of FIG. 15 is FIG. As shown in FIG. 16, a window group R410 is displayed. In this way, a list display is realized by displaying a plurality of windows.

As described above, according to the present embodiment, by executing the processing, it is possible to execute various processing by the same operation. For example, as in the present embodiment, not only the special reduced display processing but also the processing such as the list display processing 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 the processing flow in the fifth embodiment. First, when multi-touch is detected (step S502; Yes) and a pinch operation is detected (step S504; Yes), the operation start size is stored (step S506).

Here, the image resizing operation is executed according to the pinch operation (step S508). For example, in the case of the present embodiment, the pinch-out operation is performed, so that the display magnification is increased and the display image is enlarged and displayed. Note that in the case of a pinch-in operation, any of the above-described embodiments will be executed.

When the size of the enlarged display image is equal to or larger than the enlargement threshold value (step S510; Yes), it is determined whether 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 turned "ON" and identification display is performed (step S521; No->step S514->step S516).

When the size of the display image is smaller than the enlargement threshold value (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 the full screen display F is “ON” (step S524). When the full screen display F is "ON", the full screen display of the display image is performed (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).

18 and 19 show an operation example in this embodiment. 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 displayed.

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

As described above, according to the present embodiment, it is possible to perform various processes by the same operation even in the enlargement process of pinch-out. For example, like the present embodiment, in the case of enlarged display, it is possible to automatically perform full-screen display with a certain size.

[6. Sixth Embodiment]
Subsequently, a sixth embodiment will be described. The sixth embodiment will explain a case where a process is canceled by performing another operation while performing a certain operation. The operation flow of this embodiment is shown in FIG. The operation flow of FIG. 20 is a process in which steps S508 to S522 are replaced in the operation flow of FIG. Further, the same parts as those in the operation float process of FIG. 17 are designated by the same reference numerals and the description thereof will be omitted.

It is detected whether or not the display image size (window size) is equal to or larger than the enlargement threshold value and the rotation operation is performed in the state where the image is displayed for identification.

That is, when the image rotation operation is performed by the operator and the display image is in the rotating 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 the enlargement operation but not performing full-screen display. FIG. 21 is a diagram showing an operation example at this time. As shown in FIG. 21, when the operator P performs a rotation operation, the identification display is released thereafter, and the full screen display is not performed. In FIG. 21, when the rotation operation is performed, the window R600 itself also rotates the display to make the operator visually recognize that the rotation operation has been performed, but the display of the window R600 is not changed, The operator may visually recognize it by displaying an icon indicating that full-screen display is not performed.

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

In this case, the current enlarged display image may be used instead of the full screen display, or the display image may be returned to the initial value.

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

Further, in the present embodiment, the rotation operation is 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 a touch of three or more points may be newly detected.

[7. Seventh embodiment]
Subsequently, a seventh embodiment will be described. The seventh embodiment will describe an embodiment in which after the pinch-out operation is continued and the process is shifted to 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 of FIG. 22 is a process in which steps S508 to S522 are replaced in the operation flow of FIG.

After the image resizing process is executed (step S702), it is determined whether the current display image size (window size) is equal to or larger than the first threshold value. Here, if it is the first threshold value or more, 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, when the value is equal to or more than the first threshold but equal to or more than the second threshold due to the further enlargement operation (pinch-out operation), the full-screen display F is “OFF” and the identification display is It is canceled (step S704; Yes→step S706; Yes→step S714→step S716).

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

FIG. 23 is a diagram showing an operation example in the seventh embodiment. It is the figure which is further expanded operation from the state of FIG. As described above, in the display screen W700, the window R700 is an enlarged display of a part of the window R500 in FIG.

As described above, in the present embodiment, it is possible to switch a plurality of processes even with the same operation, and to realize the same operation again. In particular, in the case of a magnifying operation, there is a need to magnify and display a part, which is an effective embodiment.
