Description

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

  There is a technology for stereoscopically displaying objects such as browser focus and menus when a television or the like displays content. For example, Patent Document 1 describes a technique for stereoscopically displaying a focused component. Further, in Patent Document 2, the convenience for the user to operate the content is improved by stereoscopically displaying an object having a high priority according to the attribute of the object such as usage frequency, importance, and user preference. It is described.

JP 2004-354540 A JP 2005-49668 A

  In the conventional technology described above, the operability when the user actually operates the object is improved by considering the object to be stereoscopically displayed. However, this is always a state in which some object is stereoscopically displayed, and there is a possibility that information that the user originally does not want to see remains stereoscopically viewed. For example, there are cases where the user only wants to see information provided by train operation information of data broadcasting, news that flows in a telop, or only watching video that is being played back by a browser. At this time, if an object such as a menu or icon that the user does not need to be aware of or does not want to be aware of is stereoscopically viewed, it becomes difficult to see information or video that the user originally wants to see.

  The present invention has been made in view of such circumstances, and provides a display device, a display method, and a program capable of terminating stereoscopic display of an object that is not necessary when a user is viewing content. To do.

  In order to solve the above-described problem, the present invention includes a display unit that displays an image, an output unit that displays display data on the display unit, and a determination unit that determines whether or not an operation end has been input. And the output unit displays the object in a three-dimensional display when the determination unit determines a user input to end the operation while displaying the display data for displaying the object in the three-dimensional display on the display unit. Instead, the display device displays display data for displaying the object in a plane on the display unit.

  Further, the present invention is the above-described display device, wherein the output unit displays data for displaying the object constituting the content in a three-dimensional manner on the display unit, and for displaying the other object constituting the content on a plane. When the determination unit determines the user input to end the operation while displaying the data, the display unit displays display data for displaying the object in a plane instead of the display data for displaying the object in three dimensions. It is displayed.

  Moreover, the present invention is the display device described above, wherein the object to be stereoscopically displayed is a menu that allows a user to select an operation.

  In addition, the present invention is a display method executed by the display device, wherein the output unit displays the display data on the display unit included in the display device, and whether the determination unit inputs an operation end. A determination step for determining whether or not the output unit displays display data for stereoscopic display of the object on the display unit, and when the user input for the end of the operation is determined in the determination step, the object is stereoscopically displayed. Instead of the display data to be displayed, there is a stereoscopic display end step of displaying on the display unit display data for planar display of the object.

  Further, the present invention provides an output procedure for causing a computer used as a display device to display display data on a display unit included in the display device, a determination procedure for determining whether or not an operation end is input, and a three-dimensional object. When the display input data to be displayed is displayed on the display unit and the user input for ending the operation is determined in the determination procedure, the object is displayed in a plane instead of the display data for stereoscopic display of the object. And a stereoscopic display end procedure for displaying display data on the display unit.

  According to the present invention, it is possible to end stereoscopic display of an object that is not necessary when the user is viewing content.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an information display device 1 according to an embodiment of the present invention. As shown in the figure, the information display device 1 according to the present embodiment includes, for example, a display device 100 such as a television receiver including a display device 400 and a controller 200 that is an operation device. The display device 400 is a display capable of stereoscopic display (hereinafter referred to as “3D (three-dimensional) display”), and may require dedicated glasses.
Note that when a gesture input or a voice input is possible on the display device 100, an operation device such as the controller 200 may not be provided. The information display device 1 may be a display device 100 that includes an operation device in the same casing, such as a mobile phone terminal, a personal computer, and a game machine.

  FIG. 2 is a block diagram showing an internal configuration of the display apparatus 100, and only functional blocks related to the present embodiment are extracted and shown. As shown in the figure, the display device 100 includes a content analysis unit 110, an input unit 120, a determination unit 121, an output unit 130, and a display device 400 (display unit).

  The content analysis unit 110 acquires display content 300 that is data for displaying a content image. The display content 300 includes data for displaying an image of one or more objects. Objects include, for example, moving images, still images, texts, menu buttons, and the like. The content analysis unit 110 generates display data for each object for causing the display device 400 to display an image of the content from the acquired display content 300.

The content analysis unit 110 includes a focus position determination unit 111 and a 3D display data generation unit 113. The focus position determination unit 111 identifies the focused object based on the language description of the display content 300.
The 3D display data generation unit 113 generates 2D (two-dimensional) display data of all objects included in the display content 300, and 3D display of the object identified as being focused by the focus position determination unit 111 Data is generated. The 2D display data is display data for displaying an object on a plane as usual without performing 3D display, and the 3D display data is display data for displaying an object in 3D. The 3D display data generation unit 113 outputs the generated 2D display data of each object and 3D display data of the focused object to the output unit 130.

The input unit 120 is an interface that receives an operation input by a user. For example, the input unit 120 receives a user operation performed on the controller 200 by wireless communication such as infrared communication. Alternatively, the input unit 120 may receive an input by a user's gesture or voice. The input unit 120 may be an input device (operation device) such as a key or a button provided in the display device 100.
The determination unit 121 determines the start or end of the operation based on the user operation input to the input unit 120.

The output unit 130 causes the display device 400 to display the display data input from the 3D display data generation unit 113. When the determination unit 121 determines that the operation is started, the output unit 130 outputs the 3D display data of the focused object and the 2D display data of the unfocused object to the output unit 130, and the content image Is displayed. Further, when the determination unit 121 determines that the operation is finished, the output unit 130 outputs 2D display data for all objects to the output unit 130 to display the content image.
The display device 400 is a display capable of 3D display using an existing 3D display method.

  Next, the operation of the display device 100 will be described.

FIG. 3 is a diagram showing a display data generation processing flow in the display device 100 of the present embodiment.
The content analysis unit 110 of the display device 100 acquires the display content 300 (step S11). The content analysis unit 110 may receive the display content 300 by broadcasting or communication, and may read it from an external storage device such as a storage device or a web server (not shown) provided inside.

  The focus position determination unit 111 analyzes the language description of the acquired display content 300 and identifies a focused object among the objects included in the display content 300 (step S12).

For example, the focus position determination unit 111 identifies an object (for example, a menu button or the like) that is described as a focus target by default in the display content 300.
Alternatively, the focus position determination unit 111 identifies an object to be focused among objects included in the display content 300 based on past user input. For example, the focus position determination unit 111 stores the menu button determined by the determination unit 121 to be selected by the user from the user operation input to the input unit 120 and the number of selections. The focus position determination unit 111 determines that the frequently used menu button is the object to be focused based on the stored number of selections of each menu button.

  Alternatively, when the display device 100 is currently in the user operation mode and performing 3D display on the display device 400, the focus position determination unit 111 determines the determination unit based on the user operation input to the input unit 120. The object determined to be the operation target 121 is determined to be the focus target object. For example, if the determination unit 121 determines that a certain menu button has been selected from a user operation input to the input unit 120, the determination unit 121 notifies the focus position determination unit 111 accordingly. The focus position determination unit 111 determines that the notified menu button is an object to be focused.

The 3D display data generation unit 113 generates 2D display data for each object to be displayed, for example, by decoding the display content 300 (step S13).
For example, when the display content 300 is broadcast content, the object to be displayed is a program (moving image) of a channel selected by the controller 200, a weather forecast (still image) of data broadcasting, news (text data), data Broadcast menu button, information selected by the menu button (still image or text data), and the like.

  Further, the 3D display data generation unit 113 generates 3D display data using the 2D display data of the object specified in step S12 (step S14). As a method for generating display data for performing 3D display from display data for performing 2D display, for example, there is a method described in Japanese Patent Laid-Open No. 8-63615, but any existing method is used. be able to. The 3D display data generation unit 113 outputs the generated 2D display data of all objects and the 3D display data of the focused object to the output unit 130 (step S15).

FIG. 4 is a diagram showing a display processing flow in the display device 100 of the present embodiment.
The output unit 130 determines whether or not it is currently in the operation mode (step S21). Note that it is arbitrary whether the initial state of the display device 100 is the operation mode or the browsing mode. When the output unit 130 determines that the current viewing mode is not the operation mode (step S21: NO), the display device 400 displays the 2D display data of each object input from the 3D display data generation unit 113. (Step S22). As a result, an image of content in which all objects are displayed in 2D is displayed on the display device 400.

  The determination unit 121 determines whether an operation start is input to the input unit 120 (step S23). When the determination unit 121 determines that the operation start is not input (step S23: NO), the display device 100 repeats the process of step S22.

  When the determination unit 121 determines that the user operation input to the input unit 120 indicates the start of operation (step S23: YES), the determination unit 121 transitions to the user operation mode and outputs a 3D display request to the output unit 130 ( Step S24). At this time, when the determination unit 121 determines that the user operation indicates the start of an operation for a specific object, the determination unit 121 notifies the focus position determination unit 111 of the object. Thereby, in step S12 in FIG. 3, the focus position determination unit 111 identifies the object notified from the determination unit 121 as a focus target, and in step S14 in FIG. 3, the 3D display data generation unit 113 displays the notified object. The 3D display data is generated.

  When receiving the 3D display request from the determination unit 121, the output unit 130 determines that the operation mode has been changed, and repeats the processing from step S21. Thereby, the output unit 130 determines that the current operation mode is selected (step S21: YES), and the 3D display data of the object to be focused input from the 3D display data generation unit 113 and the object other than the focus target. The 2D display data is displayed on the display device 400 (step S25). As a result, the focused object is displayed in 3D on the display device 400, and an image of the content displayed in 2D is displayed on the other objects.

  The determination unit 121 determines whether an operation end is input to the input unit 120 (step S26). When the determination unit 121 determines that the operation end has not been input (step S26: NO), the display device 100 repeats the process of step S25.

When the determination unit 121 determines that the user operation input to the input unit 120 indicates the end of the operation (step S26: YES), the determination unit 121 transitions to the viewing mode and outputs a 3D display end request to the output unit 130 ( Step S27). When receiving the 3D display end request from the determination unit 121, the output unit 130 determines that the mode has been changed to the viewing mode, and repeats the processing from step S21. As a result, the output unit 130 determines that it is not currently in the operation mode (step S21: YES) and causes the display device 400 to display the 2D display data of each object input from the 3D display data generation unit 113 (step S21). S22). That is, the display device 100 causes the display device 400 to display the 2D display data of the object instead of the 3D display data of the object that has been displayed in 3D during the operation mode.
In this way, the display device 100 ends the 3D display in accordance with an operation end instruction from the user.

  When the user inputs an operation start of another object in step S25, the determination unit 121 determines NO in step S26. The determination unit 121 notifies the focus position determination unit 111 of an object for which an operation start has been newly instructed. Thereby, in step S12 in FIG. 3, the focus position determination unit 111 identifies the object notified from the determination unit 121 as a focus target, and in step S14 in FIG. 3, the 3D display data generation unit 113 displays the notified object. The 3D display data is generated. Accordingly, in step S25, the output unit 130 displays the 3D display data of the object for which the operation start is newly instructed and the 2D display data of other objects including the object that has been displayed in 3D so far. To display.

An example of a user operation that the determination unit 121 determines as an operation start in step S23 is shown below.
(Operation a1) The controller 200 is picked up. For example, when the controller 200 detects that the user has picked up the controller 200 based on an internal sensor, the controller 200 notifies the input unit 120 of the display device 100 to that effect.
(Operation a2) A specific gesture corresponding to the operation start is performed. In this case, the input unit 120 is a gesture input device, and the determination unit 121 determines the operation start from the result of gesture analysis by the input unit 120.
(Operation a3) The user presses the operation start key of the controller 200. The controller 200 notifies the input unit 120 of the display device 100 that the operation start key has been pressed.
(Operation a4) The user's hand existing in front of the display device 400 is started to move. The input unit 120 detects that the user existing in front of the display device 400 starts moving his hand, and the determination unit 121 determines that the operation is started from the detection result of the input unit 120.
(Operation a5) The user verbally instructs operation start. In this case, the input unit 120 is a voice input device, and outputs the result of voice recognition of the user's utterance to the determination unit 121. The determination unit 121 determines that the operation is started from the voice recognition result of the input unit 120.

In addition, an example of a user operation that the determination unit 121 determines as the operation end in step S26 is shown.
(Operation b1) The controller 200 is released from the hand. For example, when the controller 200 detects that the user has released his / her hand from the controller 200 based on a sensor provided therein, the controller 200 notifies the input unit 120 of the display device 100 to that effect.
(Operation b2) A specific gesture corresponding to the end of the operation is performed. The determination unit 121 determines the end of the operation from the analysis result of the gesture in the input unit 120 that is a gesture input device.
(Operation b3) The user presses the operation end key of the controller 200. The controller 200 notifies the input unit 120 of the display device 100 that the operation end key has been pressed. Note that an instruction to transition to the viewing mode and an operation instruction for an object different from the object to be focused currently displayed in 3D can also be regarded as an operation end for the object currently displayed in 3D.
(Operation b4) The user existing in front of the display device 400 stops the movement of the hand. The input unit 120 detects that the movement of the user's hand existing in front of the display device 400 has stopped, and the determination unit 121 determines the end of the operation from the detection result of the input unit 120.
(Operation b5) The user verbally instructs the end of the operation. The determination unit 121 determines that the operation is completed from the voice recognition result of the input unit 120 that is a voice input device.
(Operation b6) No operation is performed for a predetermined time. The determination unit 121 determines that the operation is completed when no operation is input for a predetermined time after entering the operation mode.

  FIG. 5 is a diagram illustrating a display example when 3D display is performed on the display device 400 of the display device 100 in step S25, and FIG. 6 is a display device 400 when the 3D display illustrated in FIG. It is a figure which shows the example of a display. In these drawings, an example in which a television data broadcast is displayed as content is shown.

As shown in FIG. 5, when the user operates the content, the menu button A1, which is the focused object, is displayed in 3D on the display device 400, and the other objects are displayed in 2D. When the user selects the menu button A1 with the controller 200, the information selected by the user is displayed in the information display areas A2, A3, A4, and A5 below the menu button A1. In this case, the user wants to view the information displayed in the information display areas A2, A3, A4, and A5 below the menu button A1 in order.
In addition, when the operation of the menu button A1 is terminated in the middle or when the menu button A1 is displayed in 3D by default, the user is displayed in the information display areas A2, A3, A4, A5. Sometimes you want to see the information you have.
However, this is a state in which the menu button A1 is stereoscopically viewed and information that the user does not need is displayed in the foreground. In such a display, the display of the information display areas A2 to A5 can be difficult for the user to see.

Therefore, in the present embodiment, as described above (operation b6), when the determination unit 121 detects that the user does not perform an operation, the operation ends, that is, enters the “browse content” state (browsing mode). (Step S26 in FIG. 4: YES). As a result, the display device 100 transitions to the browsing mode by the end of the operation (step S27 in FIG. 4, step S21: NO), and the output unit 130 displays all content on the display device 400 as shown in FIG. Display content as it is displayed.
In this way, the display device 100 returns to the normal display in which each piece of information is displayed at the same height, avoids unnecessary gaze, and makes it easier to see the information that the user wants to see (step S22 in FIG. 4).

  Further, as shown in FIG. 5, when the menu button A1 is displayed in 3D, the user performs an operation other than the selection operation of the menu button A1, such as an information browsing mode instruction, on the controller 200 (operation b3). The determination unit 121 determines that the operation of the menu button A1 has ended, and instructs the output unit 130 to transition to the viewing mode.

  In the above description, the case where the display device 100 is a television has been described. However, if the display device 100 is a personal computer, for example, content data to be displayed on a browser can be used as the display content 300. If the display device 100 is a game machine, screen data such as a game condition setting screen can be used as the display content 300, for example.

  According to the present embodiment described above, the display device 100 starts and ends 3D display in response to the start and end of an operation by the user. That is, the display device 100 can clearly indicate the operation start and end to the user without changing the color or layout of the original content by switching between 3D display and 2D display. In this way, when the operation is completed, the display device 100 displays the information that is desired to be viewed in an easy-to-view manner by ending the 3D display of the object that was the operation target, thereby avoiding a gaze on information unnecessary for the user. be able to.

  The display device 100 described above has a computer system therein. The operation processes of the content analysis unit 110, the determination unit 121, and the output unit 130 of the display device 100 are stored in a computer-readable recording medium in the form of a program, and the computer system reads and executes this program. Thus, the above process is performed. The computer system here includes a CPU, various memories, an OS, and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
