Display device, control method therefor, and program

The present invention relates to a display device, its control method, and a program.

Many information processing devices such as mobile phones, smart phones, tablet-type or notebook-type personal computers are equipped with display devices. Many of the images displayed on such a display device are composed of a plurality of sub-images indicating information such as text, graphics, and tables. In this way, when an image composed of a plurality of sub-images is displayed on the display device, it may be desired to show only some of the sub-images to other people. In this case, the user usually needs to cover the display area of the display device with a hand or the like to cover an area where a sub-image that the other person does not want to show is displayed.

Some display devices have a function of controlling display visibility in a display area by adjusting brightness, contrast, color, image quality, resolution, or adjusting a viewing angle. According to such a display device, the display can be made invisible by reducing the visibility. However, in such a display device, the visibility is generally controlled uniformly over the entire display area. For this reason, it is impossible to control only the visibility of a specific sub-image so as not to show only the specific sub-image among the sub-images included in the display image.

Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2009-122279) and Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2011-180603) detect a contact operation to a display unit and a contact region corresponding to the display region of the display unit, In an information processing apparatus having an operation unit that outputs a position signal indicating a position where a contact operation has been performed, a technique for receiving designation of an area on a display area in accordance with the contact operation and making the display in the designated area invisible Is disclosed.

In the techniques disclosed in Patent Document 1 and Patent Document 2, the user performs a contact operation of tracing the contact area or bringing a plurality of fingers into contact with the contact area. The information processing apparatus accepts the designation of the area on the display area based on the position on the display area corresponding to the position on the contact area indicated by the plurality of position signals output in response to the touch operation. Make the display in the area invisible. According to this technology, by performing a contact operation on an area on a contact area corresponding to an area on a display area where a sub image that the user does not want to display is displayed, the sub image can be prevented from being displayed. it can.

According to the techniques disclosed in Patent Document 1 and Patent Document 2, if the area on the display area specified in accordance with the touch operation and the area on the display area where the sub-image is displayed match, The sub-image can be hidden. Therefore, when the user does not want to show the specific sub-image to other people among the sub-images included in the display image, a part of the specific sub-image can be seen or other than the specific sub-image. It is considered that the region designated in accordance with the touch operation is made to coincide with the region on the display region where the specific sub image is displayed so that the sub image is not visible.

Here, in the techniques disclosed in Patent Literature 1 and Patent Literature 2, when the designation of the area on the display area is accepted according to the touch operation, the area on the display area in which the sub-image included in the display image is displayed Is not considered. Therefore, the area on the display area specified by the user himself / herself in accordance with the touch operation is the area on which the specific sub-image is displayed, and the area on the display area that the user actually wants to specify matches. In addition, it is necessary to adjust the area where the contact operation is performed. As a result, the area on the display area designated in accordance with the touch operation is likely to be smaller or larger than the area on the display area that the user is trying to designate. Therefore, in the technologies disclosed in Patent Document 1 and Patent Document 2, there is a problem that an area on a display area different from the user's intention may be designated as an area for controlling visibility.

In order to achieve the above object, the display device of the present invention provides:
A display unit;
An input unit that accepts input;
In the case where an image composed of a plurality of sub-images is displayed on the display unit, if an input for designating a sub-image included in the displayed image is made on the input unit, the designation is made. And a control unit that causes the display unit to display differently for the sub-image and the non-designated sub-image.

In order to achieve the above object, a display device control method of the present invention includes:
When an image composed of a plurality of sub-images is displayed and an input for designating a sub-image included in the displayed image is made, the designated sub-image is designated. Different display with no sub-image.

In order to achieve the above object, the program of the present invention

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a main configuration of a display device 10 according to an embodiment of the present invention.

The display device 10 includes a display unit 11, a detection unit 12, and a control unit 13. The detection unit 12 is an example of an input unit.

The display unit 11 displays an image in the display area under the control of the control unit 13.

The detection unit 12 detects the contact or proximity of an input unit such as a finger or a stylus pen to the display area of the display unit 11, and outputs a position signal indicating the position where the input unit is in contact or proximity to the control unit 13. Specific examples of the detection unit 12 include a capacitance type, an infrared type touch sensor, and the like. These touch sensors can output a position signal indicating each position where contact or proximity is made even when a plurality of contacts or proximity is simultaneously made to the display area.

The display unit 11 and the detection unit 12 constitute a so-called touch panel.

The control unit 13 controls display on the display unit 11.

Next, the operation of the display device 10 of this embodiment will be described.

In the following, it is assumed that the display unit 11 displays an image composed of a plurality of sub-images 21 to 28 indicating information such as text, graphics, and tables in the display area 20, as shown in FIG. . In FIG. 2, it is assumed that the display unit 11 is in a state of being displayed with the visibility determined by the initial setting or the like (hereinafter referred to as a normal state).

In the state shown in FIG. 2, it is assumed that the user shows only the sub image 25 to other people and does not want to show other sub images. In this case, the user places his / her hand in or over the area on the display area 20 where the image 25 is displayed to bring the hand into contact with or close to the display area 20. As a result, a plurality of hand contacts or proximitys to the display area 20 are performed simultaneously.

Detecting unit 12 outputs a position signal indicating each position where the hand touched or approached when detecting a plurality of hands simultaneously touching or approaching to display area 20.

FIG. 3 is a diagram illustrating an example of the area 31 of the display area 20 indicated by the position signal output from the detection unit 12. In FIG. 3, it can be seen that the user has touched or brought close to the display area 20 with the hand arcuate.

When the position signal is output from the detection unit 12, the control unit 13 specifies the shape of the region in which the hand is in contact with or close to the position signal, and the specified shape is a predetermined shape (for example, an arc shape). It is determined whether or not. When the shape of the area in which the hand is in contact or close is a predetermined shape, the control unit 13 controls the display on the display unit 11 as follows.

The control unit 13 determines whether or not the position indicated by the position signal output from the detection unit 12 is included in the area where the sub image is displayed.

When the position indicated by the position signal is included in the area where the sub image is displayed, the control unit 13 determines that an input for designating the sub image has been made.

In FIG. 3, since the sub image 25 is displayed in the area 31 indicated by the position signal, the control unit 13 determines that an input for designating the sub image 25 has been made. In FIG. 3, the sub image 22 and the sub image 23 are also displayed in a part of the region 31 indicated by the position signal. However, the control unit 13 overlaps the region 31 indicated by the position signal, for example. It is determined that an input for designating a sub-image having the largest area has been made. Usually, a blank area, a dividing line, or the like is provided between the sub-images. The control unit 13 detects the blank area and the dividing line, and specifies the area where each sub-image is displayed on the display area.

Next, the control unit 13 causes the display unit 11 to display differently for the designated sub-image and the non-designated sub-image. Specifically, as shown in FIG. 4, the control unit 13 keeps the visibility of the designated sub-image 25 out of the sub-images included in the image displayed in the display area 20 in the normal state. The visibility of the sub-images (sub-images 21 to 24, 26 to 28) that are not performed is lowered. In the following, it is assumed that the area where the visibility is lowered and the sub-image is displayed is hatched upward.

As shown in FIG. 4, by reducing the visibility of the non-designated sub-images (sub-images 21 to 24, 26 to 28), the non-designated sub-images can be made invisible to the user. . The control unit 13 controls, for example, the luminance, contrast, color, image quality, and resolution of the sub image, controls the viewing angle in the area where the sub image is displayed, performs image processing such as mosaic processing, Visibility is controlled by turning on / off the display.

Thus, in the normal state, when the position indicated by the position signal is included in the area where the sub image is displayed, the control unit 13 determines that the sub image is designated. Further, the control unit 13 reduces the visibility of the non-designated sub image while keeping the visibility of the designated sub image out of the sub images included in the display image, so that the designated sub image is not visible. For this reason, the user can hide the sub-image other than the sub-image only by bringing the input unit into or close to a part of the area where the specific sub-image is displayed. As a result, only a part of the area in which the specific sub-image is displayed is specified, or an area in which a sub-image other than the specific sub-image is displayed is different from the user's intention. The possibility that the area on the display area is designated as the area for controlling the visibility can be reduced.

In addition, in FIGS. 2-4, although the visibility of the designated sub image was maintained as it was and it demonstrated using the example which reduces the visibility of the non-designated sub image, it is not restricted to this, You may make it reduce the visibility of the designated sub image, leaving the visibility of the non-designated sub image as it is.

Further, in FIGS. 2 to 4, the control unit 13 has been described using an example in which the display unit 11 performs display control when the display state of the display unit 11 is a normal state. However, the present invention is not limited to this. For example, the control unit 13 may perform display control even when the display state of the display unit 11 is a low visibility state in which the display visibility in the entire display region 20 is reduced.

In the low visibility state shown in FIG. 5, for example, the user places his / her hand in or over the area on the display area 20 where the sub image 25 is displayed to bring the hand into contact with or close to the display area 20. Suppose. As a result, a plurality of hand contacts or proximitys to the display area 20 are performed simultaneously.

Detecting unit 12 outputs a position signal indicating each position where the hand touched or approached when detecting a plurality of hands simultaneously touching or approaching to display area 20.

When the position signal is output from the detection unit 12, the control unit 13 determines whether or not the position indicated by the position signal is included in the area where the sub image is displayed.

In FIG. 6, since the sub image 25 is displayed in the area 61 indicated by the position signal, the control unit 13 determines that an input for designating the sub image 25 has been made. In FIG. 6, for convenience of explanation, a region where the sub image 25 is displayed is indicated by a one-dot chain line, but this one-dot chain line is not actually displayed. However, a line indicating an area where the sub-images 21 to 28 are displayed may be displayed. This makes it easy to understand the area where each image sub-image is displayed.

Next, the control unit 13 causes the display unit 11 to display differently for the designated sub-image and the non-designated sub-image. Specifically, as shown in FIG. 7, the control unit 13 does not designate sub-images (sub-images 21 to 24, 26 to 28) among the sub-images included in the image displayed in the display area 20. The visibility of the designated sub image 25 is improved and the sub image 25 is made visible to the user.

As described above, when the position indicated by the position signal is included in the area where the sub image is displayed in the low visibility state, the control unit 13 has been input to specify the sub image. Is determined. Further, the control unit 13 improves the visibility of the designated sub image so that it can be seen while maintaining the visibility of the non-designated sub image among the sub images included in the display image. Therefore, the user can make the sub-image visible only by bringing the input means into or close to a part of the area where the sub-image is displayed. As a result, only a part of the area in which the specific sub-image is displayed is specified, or an area in which a sub-image other than the specific sub-image is displayed is different from the user's intention. The possibility that the area on the display area is designated as the area for controlling the visibility can be reduced.

In addition, in FIGS. 5-7, although demonstrated using the example which improves the visibility of the designated sub image with the visibility of the non-designated sub image as it is, it is not restricted to this, You may make it reduce the visibility of the non-designated sub-image while maintaining the visibility of the designated sub-image.

As shown in FIG. 4 or FIG. 7, when the position signal is not output from the detection unit 12 in a state where visibility is controlled (that is, when the user releases the display area), the control unit 13 is predetermined. After maintaining the state for the time, it returns to the original display state. Moreover, you may make it the control part 13 maintain the state until it switches the display of the display part 11 according to operation input.

As described above, according to the present embodiment, the display device 10 displays an image composed of a plurality of sub-images, and a position signal that is output in accordance with the contact or proximity of the input means to the display area of the display unit 11. Is included in the area where the sub-image is displayed, it is determined that the input for designating the sub-image has been made, and the sub-image included in the display image is designated. The sub image is displayed differently from the non-designated sub image.

When the position indicated by the position signal is included in the area where the sub-image is displayed, it is determined that the input indicating that the sub-image is designated, and the designated sub-image and the non-designated sub-image are determined. By displaying differently from the image, the sub image is specified only by bringing the input means into contact with or close to a part of the area where the specific sub image is displayed, and the specified sub image is not specified. Different display is performed for the sub-image. As a result, only a part of the area in which the specific sub-image is displayed is specified, or an area in which a sub-image other than the specific sub-image is displayed is different from the user's intention. The possibility that the area on the display area is designated as the area for controlling the visibility can be reduced.

In the above-described embodiment, the display device 10 has been described using an example in which the display unit 11 and the detection unit 12 constitute a touch panel. However, the present invention is not limited to this, and the display device 10 is a screen. It may be a projector that projects and displays an image.

When the display device 10 is a projector, a camera capable of photographing a display area where projection is performed is provided in the display device 10, and a position where the input unit is touched or approached is detected from a photographed image of the camera. Is possible.

The method performed by the display device of the present invention may be applied to a program for causing a computer to execute. In addition, the program can be stored in a storage medium and can be provided to the outside via a network.

As mentioned above, although this invention was demonstrated with reference to embodiment, this invention is not limited to the said embodiment. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
