Description

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

In recent years, various devices such as computers and AV devices that display contents have been increasing in size. Until now, operations on small and medium-sized screens have only been performed by displaying at most a few windows, but now it is possible to display large screens, expanding the range of applications for displaying a large number of contents at once. There is.

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

In addition, recently, a function capable of writing characters by handwriting or adding a mark on the displayed content may be installed. By adding such information later, it is possible to make the content stand out and record necessary instructions.

Japanese Unexamined Patent Publication No. 2013-206317

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

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

For example, even if a handwritten mark is placed on the upper left of the content to indicate that the content itself is important, the mark is also reduced when the content is reduced. This causes a problem that the marking becomes invisible.

In view of the above-mentioned problems, the present invention provides a content display device or the like whose size changes at different magnifications between the content and the additional content associated with the content.

In order to solve the above-mentioned problems, the content display device of the present invention
It includes a display unit, a control unit that superimposes a second content on the first content and displays it on the display unit, and an operation detection unit that detects an operation amount.
The control unit
The first content is displayed based on the first display magnification according to the operation amount.
The second content is displayed based on the operation amount and the second display magnification according to the type of the second content.

Moreover, the content display method of the present invention
It is a display method in a content display device including a display unit and an operation detection unit that detects an operation amount.
A step of superimposing the second content on the first content and displaying it on the display unit,
A step of displaying the first content based on the first display magnification according to the operation amount, and
It is characterized by including a step of displaying the second content based on a second display magnification according to the operation amount and the type of the second content.

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

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. For convenience of explanation, an embodiment will be described as an example, but it goes without saying that any device capable of displaying operations can be applied.

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

Here, the display device 10 can be operated by a plurality of operators depending on the size and shape of the display unit. For example, it can be used for business negotiations facing the display and for various meetings by operating from four directions.

In the present embodiment, the touch panel is used as the content as a display device, but other devices may be used as long as the content can be displayed and the operation can be detected. For example, it is sufficient that the content can be displayed by a projector and the same function can be realized, such as a content display system capable of detecting an operation on the content by detecting an operation of a space sensor or an operation pen.

[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 types of information. For example, it is composed of a liquid crystal display (LCD), an organic EL display, and the like.

The input detection unit 130 is a functional unit that can detect an input from an 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, 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 for expanding the content read from a file or the like, outputting a display image, or performing image processing such as a filter on the image. Here, the description of the conventional image processing (for example, extracting an image to be displayed from the content or simply enlarging / reducing the displayed image) will be 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 composed of 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 has a main content data storage area 162 for storing the main content and an additional content data storage area 164 for storing the additional content.

The content (main content) displayed on the display unit 120 is stored in the main content data storage area 162. This content may be, for example, character data, image data, video data, or 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 main content may be received from another device by, for example, a communication means, or may be read from an external storage device. Further, it may be generated by the display device 10 or may be input by a scanner or the like.

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

Then, the additional content is stored in the additional content data storage area 164 in association with the main content. As the additional content, for example, it is stored in association with the identification information of the main content (uniquely identifiable information such as a file ID, a file number, and a content ID).

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

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

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

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

[1.3 Processing flow]
Subsequently, the flow of processing in the first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a main process in the present embodiment.

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

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

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

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

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

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

Although the multi-touch is detected and determined for the reduction operation, which is one of the display magnification changing operations in FIG. 4, it goes without saying that another display magnification changing operation may be used. For example, it may be another gesture input, or another reduction operation such as touching the displayed reduction button may be detected.

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

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

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

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

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

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

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

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

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

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

Since the coordinates of the vector data may be recalculated based on the magnification, for example, in step S156, the calculation may be performed at the timing of displaying the reduced image. That is, the magnification (reduction magnification) may be managed together without generating the reduced image.

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

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

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

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

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

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

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

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

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

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

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

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

The area R210 including the additional content of the handwriting input is determined as the additional area. Then, as shown in R220 of FIG. 11, the main content and the additional area including the additional content are displayed at different magnifications (reduction ratios).

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

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

Specifically, additional content is input to the main content displayed on R300 of the display screen W300 of FIG. Here, the additional content is input at positions distant from R310 and R320. In this case, the additional content of R310 and the additional content of R320 are recognized as different additional contents. This is because R310 and R320 are written at positions separated from each other.

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

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

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

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

[6. 6th Embodiment]
Next, the sixth embodiment will be described. The sixth embodiment describes a case where the additional content is also reduced and displayed in real time. The sixth embodiment has the same configuration as the first embodiment, and the processing of FIGS. 4 and 5 is replaced with that of FIG. The same processing as in FIG. 4 is designated by the same reference numerals, and detailed description thereof will be omitted.

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

Subsequently, in addition to the resizing process of the main content (step S108), the reduction / display process of the additional content is performed (steps S204 and S206). Note that steps S204 and S206 are substantially the same processes as steps S154 and S156 in FIG.

That is, in the present embodiment, in step S108, the content whose main content is reduced by the resizing process is displayed, and at the same time, the content whose additional content is reduced is displayed. As a result, the user can perform the reduction operation while checking the actual size of the added content.

An operation example will be described with reference to the figure. FIG. 15 is a diagram showing an example of the display screen W400. The main content R400 is displayed, and the additional content R410 is displayed. Here, the state in which the reduction operation (pinch-in operation) is performed is shown in FIG. At the same time that the main content is reduced and displayed as R420, the additional content is also reduced and displayed as shown in R430. Here, the magnification (reduction ratio) of R420 and R430 is different.

Then, the case where the pinch-in operation is canceled is shown in FIG. Although the main content is displayed on R440, additional content having different magnifications (reduction ratios) is also displayed. As described above, in the present embodiment, the user can also confirm the size of the additional content and perform the reduction operation.

[7. Seventh Embodiment]
Subsequently, the seventh embodiment will be described. A seventh embodiment describes a case where the additional content is gradually reduced and displayed. The configuration of the seventh embodiment is the same as that of the first embodiment, and the processing of FIGS. 4 and 5 is replaced with that of FIG. The same processing as in FIG. 4 is designated by the same reference numerals, and detailed description thereof will be omitted.

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

Subsequently, in addition to the main content resizing process (step S108), if the additional content matches the reduction condition (step S302; Yes), the additional content reduction / display process is performed (step S108). S304, S306). Note that steps S304 and S306 are substantially the same processes as steps S154 and S156 in FIG.

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

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

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

Then, when the additional content and the main content have almost the same size (the number of pixels in the vertical direction of the main content is the same as the number of pixels in the vertical direction of the additional area including the additional content), the additional content is reduced and displayed. NS.

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

Further, since the additional content is gradually reduced and displayed, it may be reduced and displayed first. In this case, in step S302 of FIG. 18, the processing of “Yes” and “No” is performed in reverse.

For example, the reduced display may be performed up to "100" on one side of the number of pixels of the additional content, but when the number of pixels becomes "100", the reduced display of the additional content may not be performed thereafter.

[8. 8th Embodiment]
Next, the eighth embodiment will be described. The eighth embodiment describes an embodiment in which the method of reducing the additional content is changed depending on the operation method. It should be noted that this embodiment can be applied to any of the above-described embodiments. For example, the configuration is the same as that of the first embodiment, and the processes of FIGS. 4 and 5 are replaced with those of FIG. The same processing as in FIG. 4 is designated by the same reference numerals, and detailed description thereof will be omitted.

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

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

Here, when the second operation is detected (step S404; Yes), the main content and the additional content are integrally reduced and displayed (step S410). That is, the main content and the additional content displayed at that time are subsequently reduced and displayed at the same magnification (reduction ratio), and the main content and the additional content are reduced and displayed in conjunction with each other. It becomes.

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

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

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

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

[9. 9th Embodiment]
Subsequently, the ninth embodiment will be described. A ninth embodiment describes a case where the reduction method is switched according to the type of the additional content. The ninth embodiment has the same configuration and processing as the above-described embodiment (for example, the first embodiment).

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

Here, in the case of the present embodiment, the reduction ratio of the text content is slower than that of the main content, and other contents (for example, the handwritten input content of the lower right star picture) are reduced in the same manner as the main content. It is set to be reduced by the rate.

In this case, like the main content displayed in R710 of FIG. 25, the text content is displayed large, but the handwritten content is displayed small. In this way, it is possible to change the reduction ratio according to the attributes of the content.

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

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

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

For example, four main contents are displayed on the display screen W800 of FIG. 26. That is, although they are displayed as R800, R810, R820, and R830, the additional contents displayed on R800 and R830 are substantially the same.

Whether or not the additional contents are the same may be determined by detecting, for example, substantially the same shape, or by the type of the additional contents. Further, those having the same characters / symbols recognized from the input additional content may be determined as the same additional content.

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

Then, it becomes possible to execute a process such as arranging the selected contents as shown in FIG. 28 or saving as shown in FIG. 29.

[11. 11th Embodiment]
Next, the eleventh embodiment will be described. The eleventh embodiment is an embodiment in which when the main content is expanded, the additional content is suppressed so as not to be unnecessarily expanded.

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

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

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

If this embodiment is not applied, the text content, which is the additional content, will be displayed in a large size as shown in FIG. 31. Compared to this, in FIG. 30, it is enlarged to an appropriate size, and it is possible to suppress unnecessarily large display.

[12. Modification example]
Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and the design and the like within a range not deviating from the gist of the present invention are also within the scope of claims. include.

Although the large content display device has been described in the above-described embodiment, it may be a small content display device or a terminal such as a tablet. Of course, it can also be realized in other devices such as a touch-input TV and a car navigation system.

Further, although the above-described embodiments are described separately for convenience of explanation, they may be operated in combination through the specification as needed.
