Description

  The present invention relates to an electronic device equipped with multi-view directional display means, a method for selecting a function effective for a screen, and a program. The present invention relates to an individual terminal such as a mobile phone or a PDA, a car navigation system, or a TV. It is suitable to apply.

A liquid crystal display panel has a liquid crystal layer having an anisotropic dielectric constant injected between two substrates. By adjusting the strength of an electric field applied to the liquid crystal layer, the light transmitted through the substrate is transmitted. It is a display that adjusts the amount and displays a desired image.
Such a liquid crystal display panel is excellent in weight reduction, thinning, low power consumption, and the like, and is not limited to familiar devices such as a mobile phone, a car navigation system, a PDA (Personal Digital Assistant), a personal computer, and a television receiver. It is used as a display device for measuring equipment, medical equipment, industrial equipment in general.

  Such a liquid crystal display panel is not limited to video display in television reception, but can display video from a source source such as video, CD (Compact Disc), DVD (Digital Versatile Disk), etc. When displaying an image from another source source while displaying an image, an input source source is switched from a certain source source to another source source.

  For example, in a device equipped with a multi-display function, it is possible to divide a display area of a liquid crystal display panel into a plurality of parts and display a video of a channel in each display area and a video from another source source. However, in this case, the images displayed in the respective display areas can be seen at the same time, so that the displayed images cannot be viewed in a concentrated manner, and the respective display areas become smaller, so they are displayed. There is a problem that the image becomes smaller.

Therefore, by adopting the dual view display technology proposed in Patent Document 1 proposed by the present applicant, video from one source source and video from other source sources without changing the size of the display area. Dual view display in which both are displayed simultaneously becomes possible.
That is, dual view display is to display images from two viewpoints separately on the same screen so that different images can be visually recognized depending on the viewing direction.

  Here, the basic principle of the dual view display technology will be described. In the dual view display, as shown in FIG. 17, a parallax barrier (optical system separation element) 2 is arranged on the entire surface of a liquid crystal display panel 1 having a plurality of pixels a and b. The parallax barrier 2 is a screen having a plurality of vertical translucent slits separated by opaque regions.

  The light that has passed through the pixels a of the liquid crystal display panel 1 reaches the viewer A side located at a predetermined viewing angle with respect to the display surface of the liquid crystal display panel 1 through the translucent slits of the parallax barrier 2. . Further, the light transmitted through the pixel b of the liquid crystal display panel 1 passes through the translucent slit of the parallax barrier 2 to the viewer B side positioned at a predetermined viewing angle with respect to the display surface of the liquid crystal display panel 1. To reach.

Different images displayed on the liquid crystal display panel 1 are made visible only by a plurality of translucent slits of the parallax barrier 2 from a predetermined region in the space. Thereby, viewer A and viewer B can see different images, respectively.
Hereinafter, display means that can be displayed in a visually recognizable manner from two or more display directions will be referred to as multi-view directivity display means.

By the way, in a device using a liquid crystal display panel, there is a device that can operate a still image or a moving image displayed on the liquid crystal display panel by an operation of a touch panel without being limited to an operation of a remote controller.
The touch panel is superimposed on the entire surface of the liquid crystal display panel, and touches a touch operation screen on which, for example, a bar or a key switch is displayed in accordance with an operation selection instruction displayed on the liquid crystal display panel. Operation control can be performed.
In other words, the content of the touch operation screen itself becomes a switch, and intuitive operation can be performed. In addition to improving visibility and operability, various functions can be freely controlled. . As a touch panel system, an electromagnetic induction type, an electric resistance type, a capacitance type, a pressure sensitive type, and the like are known.

When each of the images displayed using the dual view display technology of Patent Document 1 is operated with a key, a remote controller, a touch panel, or the like, it is necessary to recognize which image is the operation. is there.
For example, in the display device of Patent Document 2, a viewer A touch-dedicated area and a viewer B touch-dedicated area are provided on the touch panel, and the viewer A touch-dedicated area or the viewing is based on the coordinate data of the touch position detected by the touch panel. It is determined which of the viewer B touch-dedicated areas has been touched, and the display operation is controlled by recognizing the video corresponding to the touched viewer A touch-dedicated area or viewer B touch-dedicated area. Thereby, in the dual view display, it is possible to easily and reliably determine which video the touch operation is effective for.

  Further, the display device of Patent Document 3 recognizes an image corresponding to the position of the remote control detected by the remote control position detection sensor, and remotely operates the image of the recognition result. This eliminates the need for a selection operation for corresponding remote control by the remote controller to each image.

  Further, the display device of Patent Document 4 simultaneously displays an image and an icon that can be viewed from the first viewing angle direction and an image and an icon that can be viewed from the second viewing angle direction, and is displayed at a position indicated by the user. The data supplied to the display means is controlled in accordance with the instructions defined in (1). Thereby, operation suitable for the image visually recognizable from each viewing angle direction can be performed.

  However, in the techniques of Patent Documents 2 and 4 using a touch panel, a dedicated area or icon for each screen is provided to identify an operation on the screen corresponding to the selected area or icon. . However, since an area and an icon for each screen are provided, the operation range is limited.

  Further, in the technique of Patent Document 3 using a remote controller, which screen is being operated is identified based on the detected operation position of the remote controller. However, it is always cumbersome to move one remote controller or operate it by preparing multiple remote controllers corresponding to the screen, being aware of which screen is the operation target. .

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an electronic apparatus according to the invention will be described with reference to the drawings.

First, the outline of the present invention will be described.
The electronic device of the present invention is equipped with multi-view directional display means capable of separately displaying images from two viewpoints on the same screen so that different images can be visually recognized depending on the viewing direction. For example, a user, a thing such as a hat or emblem, or a plant or animal) is detected, and an effective function is selected from the detection result.
Then, it becomes possible to perform input / output control and the like with respect to the enabled function (for example, application program). Examples of the input / output control include key operations such as a touch panel and cursor keys, voice input / output control, voice output directivity control, and image input / output control.
Here, the direction in which the detection target is present is determined as follows.

(A) A camera is used.
For example, as shown in FIG. 1A, the display means can display the left and right screens in a multi-view manner, and a music application and mail software are displayed on each screen. The user can check the screen of the music application from the position A, and can check the mail contents of the mail software from the position B.
And the camera which image | photographs in which direction of a display means a detection target (user) is installed in the center of a display means. As shown in FIG. 1B, the image of the detection target (user) at position A is shown on the right and the detection target (user) image at position B is shown on the left. Yes.
If the detection target (user) is shown on the right side of the image captured by the camera as shown in FIG. 1C, the function corresponding to the screen viewed from the position A is effective as shown in FIG. Thus, the music volume can be adjusted.

On the contrary, if the detection target (user) is shown on the left side of the image captured by the camera, the function corresponding to the screen viewed from the position B becomes effective, and the mail software can be operated.
In addition, the detection target is not a user but a specific object (for example, a hat or a patch), and the function corresponding to the screen viewed from the position A is enabled by placing the detection target at the position A. By moving to the position B, the contents of the mail can be viewed from the position B.

(B) A detection target with an RFID attached is used.
For example, as shown in FIG. 2A, the display means can display the left and right screens in a multi-view manner, and a music application and mail software are displayed on each screen. The user can check the screen of the music application from the position A, and can check the mail contents of the mail software from the position B.
A reader that reads the ID card (detection target) with the RFID attached is installed on the side of the user who views each screen. In this case, two readers are installed on the right side and the left side of the display unit, but the reader and the display unit may be provided integrally or separately.

Next, consider a case where a user wants to operate a music application.
As shown in FIG. 2B, when the user has an ID card (detection target) attached with an RFID and moves to position A, the right reader reads the user's ID card (detection target) and the right side The function corresponding to the screen is enabled, and the volume of music can be adjusted.
Conversely, when the user has an ID card (detection target) and moves to the left side of the display means, the left reader reads the user's ID card (detection target), and the function corresponding to the left screen becomes effective. You will be able to operate mail software.
In addition, when using the detection target to which this RFID is attached, by moving only the detection target to the reading range of the left and right readers, the user does not move, and the function for the screen on the opposite side of the position where the user is located is provided. It can also be enabled.

(C) An inclination sensor mounted on a small electronic device is used.
For example, in a small electronic device having display means capable of multi-view display of left and right two screens as illustrated in FIG. 3, a music application is displayed on the screen on the right side when viewed from the small electronic device. Assume that mail software is displayed on the screen. At this time, if the user tilts the small electronic device to the right, the screen of the music application can be viewed by tilting the screen of the music application to the left. When a tilt sensor is mounted on this small electronic device, it can be detected whether the small electronic device is tilted to the left or right side, so that a screen for enabling various functions can be automatically determined.
In this example, if the small electronic device is tilted to the right side, the tilt sensor determines that the small electronic device is tilted to the right side, that is, the user is looking at the screen displaying the music application, The music application can be operated. Conversely, if the small electronic device is tilted to the left, the tilt sensor detects that the small electronic device has been tilted to the left, that is, the user is looking at the screen displaying the mail software. Can be operated.

As described above, a screen for a function that has become effective may be distinguished from a screen for a function that is not effective in combination with any of the following (FIG. 4).
-The color of the frame of the screen corresponding to the activated function is displayed so as to be identifiable (FIG. 4A).
-The thickness of the screen frame for the activated function is displayed so as to be identifiable (FIG. 4B).
Display distinguishable icons, pictures, characters, symbols, etc. on the screen for the activated function (FIG. 4C). These display positions and sizes can be freely set.
When photographing the detection target with the camera, the captured detection target is displayed as a part of the screen for the activated function (FIG. 4D). This display position and size can be freely set.

Further, as shown in FIG. 5, when a plurality of persons are viewing a plurality of multi-view screens, it is necessary to determine which screen can be operated. For this purpose, an operable screen is specified by authenticating the detection target. In this case, the detection target is an authentication target.
However, when a plurality of authentication targets are authenticated, priorities are given to the authentication targets and an authentication target with a higher priority is selected.

  For example, by setting the authentication target as a specific person or thing (hat, emblem, animal or plant, etc.) and authenticating the specific person or thing from the images taken by the camera, the operation on the screen showing the authentication target is performed. It becomes possible.

Further, when the authentication is denied, the functions corresponding to all the screens of the display means can be invalidated so that these functions cannot be operated.
Further, the authenticated authentication target may be displayed as a part of the operable screen as shown in FIG. This display makes it easy to understand what is authenticated. This display position and size may be fixed or may be set freely in advance.

Further, when the electronic device has a communication function, if an incoming call is notified to a screen during work or viewing, the work or viewing is hindered.
For this purpose, the screen that is in the selected state or the non-selected state is automatically determined, and the screen that is in the selected state becomes the non-selected state according to the function that is enabled on each screen. An incoming call is notified either on the current screen or on both screens.

For example, when notifying a user that an e-mail has arrived, if the user is watching a movie on the selected screen, it will be difficult to view if the notification message is displayed on this screen. The incoming call notification is notified to the non-selected screen.
However, simply displaying the notification message on the non-selected screen may not be noticed by the user, so display the notification message on the selected screen, or It is also possible to make an incoming call notification by ringing.

Also, for example, if the user is watching a movie on a screen that is not selected, and is watching music on a screen that is selected, the notification message is not selected. If it is displayed on the screen, it is difficult to watch a movie. Therefore, the incoming call notification is notified to the selected screen.
However, simply displaying the notification message on the screen that is in the selected state may not be noticed by the user, so it is possible to display the notification message on the screen that is in the non-selected state, or make a sound. It is also possible to make an incoming call notification by ringing.

  Furthermore, when there is one user, the screen that the user is not viewing may be turned off. Thereby, since the display means is not operated, power consumption can be reduced.

Next, when there are a plurality of detection targets (hereinafter referred to as authentication targets in the second embodiment), the detection unit 31 that determines a specific authentication target from among them will be described.
When a plurality of authentication targets are targeted, an authentication system is used to identify one authentication target.

An authentication file 313 storing the following data for each authentication target is prepared in advance.
Authentication object identifier: an identifier for identifying an authentication object.
Authentication image: This is a photographed image to be authenticated, and it is checked whether this authentication image is present in the image photographed by the photographing unit 311.
Priority: When a plurality of authentication targets are found, it is assumed that an authentication target with a high priority is authenticated.

The image authentication unit 312 starts the operation of the photographing unit 311 and searches whether the photographed authentication target image is registered in the authentication file 313.
When there is one search result, the searched authentication target identifier is output.
When there are a plurality of search results, the identifier of the authentication target having the highest priority among the search results is output.
If there is no search result, the fact that there is no authentication target is output.

  The detection unit 31 extracts an authentication image corresponding to the authentication target identifier output from the image authentication unit 312 from the image captured by the imaging unit 311, and determines the authentication target from the position of the captured image where the authentication target exists. A certain direction is determined, a screen corresponding to this direction is determined, and a screen identifier for identifying the screen is output to the function selection unit 32.

  In addition, when the image authentication unit 312 outputs “the authentication target does not exist”, the detection unit 31 outputs “no output to all screens” to the control unit 33, and the control unit 31 In 33, output to all the screens of the multi-view display is not displayed (clear screen).

Next, a process for selecting an effective function will be described with reference to the flowchart of FIG.
An image is acquired by the imaging unit 311 (step S11), and it is searched whether the authentication target image that has been captured is registered in the authentication file 313 (step S12).
Here, when a plurality of authentication targets are registered, it is assumed that the authentication target having the highest priority has been authenticated.

When the authentication is successful (step S13 / YES), an authentication image corresponding to the authenticated authentication target identifier is extracted from the image captured by the imaging unit 311 (step S14).
Next, the direction in which the authentication target exists is determined from the position of the photographed image where the authenticated authentication target exists, and the screen identifier of the screen corresponding to this direction is determined (step S15).

With reference to the function list 36, the function corresponding to the screen identifier is selected as an effective function (step S16).
Here, the screen indicated by the screen identifier may be distinguished from the screen for the function which is in the non-selected state by any one or combination of the following (FIG. 4).
The screen frame color indicated by the screen identifier is displayed in an identifiable manner (FIG. 4A).
The thickness of the screen frame indicated by the screen identifier is displayed so as to be identifiable (FIG. 4B).
A distinguishable icon, picture, character, symbol, or the like is displayed on the screen indicated by the screen identifier (FIG. 4C). These display positions and sizes can be freely set.
The authentication target is displayed as a part of the screen indicated by the screen identifier (FIG. 4D). This display position and size can be freely set.

  On the other hand, if the authentication is denied or there is no authentication target (step S13 / NO), the output to all the screens of the multi-view display is hidden (clear screen) as a denial process (step S17). .
