## Title
Stereoscopic-image display apparatus and stereoscopic eyewear

## Abstract

In the case of plural viewers viewing the 3D image, it is difficult to implement the display condition requested by the individual viewer without the viewer's burden for manipulating to change to the image requested by the viewer.
A stereoscopic-image display apparatus is provided with a viewer detecting unit that identifies the viewer, and a viewer/stereoscopic eyewear database that stores and manages individual data for each of the viewers and stereoscopic eyewears. The stereoscopic-image display apparatus automatically instructs the stereoscopic eyewear utilized by the viewer to implement the display condition requested by the viewer.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is the national phase under 35 U.S.C.§371 of PCT International Application No. PCT/JP2011/080450 which has an International filing date of Dec. 28, 2011 and designated the United States of America.
FIELD OF THE INVENTION
The present invention relates to a stereoscopic-image display apparatus and stereoscopic eyewear that change a stereoscopic (3D) image and a planar (2D) image based on the display condition requested by the plural viewers who view a stereoscopic (3D) image.
BACKGROUND OF THE INVENTION
Although having become increasingly popular, the 3D image is recently made on the basis of the binocular parallax technology. For example, a non-patent document 1 shows a technical explanation regarding the 3D image and a safety guideline regarding the 3D image. The human recognizes image signals generated from two view points, i.e., the right eye and left eye, and thus determines whether an object is stereoscopic or not. The distance of human's right eye and left eye is about 5-7 cm varied from a child to an adult. Therefore, the images accepted by right and left eyes are respectively different because of the viewer's view points. The difference becomes larger when the distance to the object is closer, and becomes smaller when the distance to the object is farther. The brain perceives on the basis of the parallax caused by the both eyes whether the object is stereoscopic or not.
As respectively giving images made from different view points to the right eye and left eye, the viewer can feel the depth of image. The 3D display utilizing the binocular parallax is a technology, which utilizes a 3D eyewear, such as a liquid crystal shutter, and independently and repeatedly gives images to the right and left eyes. For example, when the right eye's image and left eye's image are sequentially arranged on a display based on that principle, the image shown on the display looks like stereoscopic and the human can perceive the stereoscopic image protruding back and forth with respect to the display surface. When the degree of parallax is increased, the back and/or forth protruding amounts become larger. Thus, using the 3D eyewear, such as a liquid crystal shutter, can enhance the impression and surprise to the viewer who is viewing the image.
Some eyewear is commercially available as the 3D eyewear dedicated for the 3D TV, which includes a changing switch for changing from the 3D image to the 2D image. When a viewer wearing the 3D eyewear views the 3D image and have tired eyes, the viewer can double-click the changing switch for forcibly changing the 3D image into the 2D image. When the changing switch is clicked to select the change into the 2D image with the eyewear having the liquid crystal shutter that is utilized for the 3D TV and alternately shows the right eye's image and left eye's image, respective liquid crystal shutters for the left and right eyes open the shutters at the same timing for showing the right eye's image or left eye's image. Thus, the same image can be given to the viewer's both eyes, i.e., the right eye's image or left eye's image.
A patent document 1 shows a stereoscopic-image display apparatus that includes a reflecting member on a frame of a 3D eyewear, and a display device having a means for emitting light and a light receiving means for receiving reflected light, and that receives light reflected from the 3D eyewear to determine whether the 3D eyewear is worn or not and then to change the display from the 3D image to the 2D image. FIG. 6 is a perspective view that shows a schematic configuration of the stereoscopic-image display apparatus in the patent document 1. In this stereoscopic-image display apparatus, the right eye's image and left eye's image are alternately displayed, similarly to the 3D TV described above. The stereoscopic-image display apparatus emits light for detecting the wearing condition, and checks whether or not light reflected from the reflecting member arranged on the frame of the 3D eyewear is received. When having received the reflected light, the stereoscopic-image display apparatus determines that the viewer is wearing the 3D eyewear and continues displaying the 3D image. The viewer wearing the 3D eyewear can view the 3D image. When having not received the reflected light, the stereoscopic-image display apparatus determines that the viewer is not wearing the 3D eyewear. Then, the stereoscopic-image display apparatus generates any one of the right eye's and left eye's images described above, and automatically changes into the 2D image without the viewer's manipulation.

SUMMARY OF THE INVENTION
Problems to be Solved by the Invention
However, it is known by experts that 4%-10% of the human cannot recognize that the 3D image made with the method described above is the 3D image. Because of any reason (strabismus, amblyopia, astigmatism or the like), they cannot control both eyes to focus in the same space. They perceive that the 3D image made with the method described above is the degraded 2D image. Thus, they will be discomforted and/or have a headache. When they want to enjoy 3D TV program with other people and to view the TV program as the 2D image, they have to do the manipulation of changing into the 2D image with wearing the eyewear each time. It will annoy the viewers.
In addition, viewing continuously the 3D image made with the method described above during a long period of time can cause the eye strain and viewers will be discomforted and/or have headaches. When plural persons simultaneously view the same TV program and all of them want any one of the 3D and 2D images, the stereoscopic-image display apparatus shown in the patent document 1 may be enough. However, when plural persons want different images from each other, the stereoscopic-image display apparatus shown in the patent document 1 is not enough.
Thus, the present invention is made in order to solve the problem described above, and has an object to implement the display condition requested by the viewer with automatically determining and displaying the 3D image or 2D image based on the viewer who wear the 3D eyewear, without requiring the viewer to perform the changing manipulation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Embodiments of the present invention are described below with reference to figures.
Embodiments
Embodiment 1
FIG. 1 is a functional block diagram that shows a configuration of main parts included in a stereoscopic-image display apparatus 100 of an embodiment according to the present invention and is a functional block diagram that shows a stereoscopic eyewear 200 of an embodiment according to the present invention.
The stereoscopic-image display apparatus 100 is configured with a viewer detecting unit 101 that is utilized for identifying a viewer and a stereoscopic eyewear 200 worn by the viewer, a viewer/stereoscopic eyewear database 102 that stores and manages respective individual data of the viewer and stereoscopic eyewear 200, a controlling unit 103, a sending unit 105 that is utilized for sending to a stereoscopic eyewear 200 of a synchronizing signal synchronized with display timings of a right eye's image and left eye's image, a control signal utilized for changing a view mode of the stereoscopic eyewear 200 between the 3D mode and 2D mode, and the like, a tuner unit 106 that is utilized for receiving the broadcast wave, and an external input unit 107 that is utilized for connecting input signals obtained from the outside.
In addition, the stereoscopic eyewear 200 is configured with a receiving unit 201 that is utilized for receiving and separating the synchronizing signal and control signal sent from the stereoscopic-image display apparatus 100, a synchronizing circuit 202 that receives the synchronizing signal separated by the receiving unit 201, a controlling unit 203 that receives the control signal separated by the receiving unit 201, a right eye's shutter 204 that is utilized for viewing the right eye's image for the 3D image, a left eye's shutter 205 that is utilized for viewing the left eye's image for the 3D image, and a wear/non-wear detecting unit 206 that detects whether the viewer wear the eyewear or not. An eyewear 1, and eyewear 2 to eyewear n−1 are stereoscopic eyewears configured similarly to the stereoscopic eyewear 200.
The image processing unit 108 detects whether a broadcast program received by the tuner unit 106 of the stereoscopic-image display apparatus 100 contains the 3D image or 2D image. Then the image processing is performed on the received broadcast program, and the received broadcast program is displayed as the 3D image or 2D image on the display unit 109 based on the sending timing from the controlling unit 103. When the received broadcast program contains the 2D image, the sending unit 105 does not need sending the synchronizing signal to the stereoscopic eyewear 200 and thus the controlling unit 103 instructs the sending unit 105 to stop sending the synchronizing signal or to keep the stop condition. When the received broadcast program contains the 3D image, the controlling unit 103 instructs the sending unit 105 to start sending the synchronizing signal or to keep the sending condition.
Similarly, it is described about the case that the image displayed on the display unit 109 is a source image based on the external input unit 107. When the image displayed on the display unit 109 is not the broadcast program obtained from the tuner unit 106 but a source image obtained from other filming equipment, such as a BD/DVD player and CATV tuner, the image processing unit 108 detects whether the source image contains the 3D image or only the 2D image. When the source image contains the 3D image, the image processing is performed on the source image. Then, the source image is displayed as the 3D image on the display unit 109 based on the sending timing from the controlling unit 103. Similarly, the instruction to start sending the synchronizing signal or to keep the sending condition is given to the sending unit 105. When the source image contains only the 2D image, only the source image input into the external input unit 107 is displayed. Then, the instruction to stop sending the synchronizing signal or to keep the stop condition is given to the sending unit 105, when the synchronizing signal is being sent.
Furthermore, the stereoscopic-image display apparatus 100 includes the viewer detecting unit 101 for detecting a viewer who views the 3D image or 2D image displayed on the display unit 109. The viewer detecting unit 101 detects the stereoscopic eyewear 200 worn by the viewer, too. The viewer detecting unit 101 is configured with a camera for capturing the viewer and stereoscopic eyewear 200 as image data, with an image coding circuit for coding the captured image data into specific compressed images, with a memory for performing the coding processing, and the like. The stereoscopic-image display apparatus 100 utilizes the viewer detecting unit 101 to capture the image data of a viewer who has never utilized before, and stores image data utilized for individually determining the viewer into the viewer/stereoscopic eyewear database 102.
Although not shown, the stereoscopic-image display apparatus 100 includes a viewer registering means and eyewear registering means for registering the viewers utilizing the present apparatus and stereoscopic eyewear 200 being utilized with the present apparatus. For example, a registration button may be provided on a remote controller or the like, for registering the viewers and stereoscopic eyewear 200. When the registration button is pushed, the display unit 109 displays the selection screen showing a “registration of viewer”, “registration of stereoscopic eyewear”, “registration of both viewer and stereoscopic eyewear” or “return”. The viewer comes in front of the viewer detecting unit 101 included in the stereoscopic-image display apparatus 100 with wearing the stereoscopic eyewear 200, and utilizes the remote controller to select any of the registration items after pushing the registration button. When the “return” button is pushed, processing regarding the registration is aborted and the initial condition is returned. When the buttons other than the “return” button are pushed, the camera of the viewer detecting unit 101 zooms up the object, such as the viewer and stereoscopic eyewear 200 and captures the image data having an appropriate size for the registration.
When the “registration of viewer” has been selected at that time, the viewer detecting unit 101 detects a person in the image captured by the camera, performs zooming to make the entire of the detected person be shown, and capture the image. Alternatively, it may be configured to extract a face portion and capture it. It may be configured to capture the upper body portion. In addition, it may be configured to capture an image whose size is selected by the viewer.
When the “registration of stereoscopic eyewear” has been selected at that time, the viewer detecting unit 101 detects the viewer's face shown in the image captured by the camera, zooms up the portion of the stereoscopic eyewear 200 worn by the viewer, and captures the image data of the stereoscopic eyewear 200 having an appropriate size for the registration.
When the “registration of both viewer and stereoscopic eyewear” has been selected at that time, the viewer detecting unit 101 sequentially performs the operation performed in the case that the “registration of viewer” is selected and the operation performed in the case that the “registration of stereoscopic eyewear” is selected. Since there is no priority, any one of the operations can be performed initially.
The captured image data is provisionally stored as an image file compressed by a predetermined image compression coding in the memory utilized for the coding processing. The image data stored in the memory utilized for the coding processing is displayed on the display unit 109, to ask the viewer whether or not the viewer allows registering the image data in the viewer/stereoscopic eyewear database 102. When the viewer allows of registration, the controlling unit 103 stores the image data displayed on the display unit 109 as the image data utilized for the “registration of viewer” or for the “registration of stereoscopic eyewear” in a predetermined region of the viewer/stereoscopic eyewear database 102. The image compression coding method utilized for the registration image data may be the JPEG, TIFF, GIF, PDF or the like.
Although the registration method utilized for registering the viewer and stereoscopic eyewear 200 in a condition of the stereoscopic eyewear 200 being worn is described above, it may be configured that the viewer and stereoscopic eyewear 200 are separately registered, and that the search data is generated by combining the image data of the viewer not wearing the stereoscopic eyewear 200 and the image data of the stereoscopic eyewear 200 when the data search is performed about the viewer who views the stereoscopic-image display apparatus 100.
In addition, it may be configured that a menu type interface is prepared for allowing the viewer to input other individual data regarding the viewer and stereoscopic eyewear 200, while the viewer registering means and eyewear registering means are utilized for registering the image data of the viewer and stereoscopic eyewear 200. For example, it is possible as the viewer's individual data to utilize several items other than viewer's image data, such as a registration number K, mode selection, name, age, height, sex, nickname, and favorite category. It is possible as the individual data regarding stereoscopic eyewear 200 to utilize several items other than image data of the stereoscopic eyewear 200, such as a registration number G, mark position, serial number, manufacture's name, model name, model number, color, and year's type. It may be configured about the individual data of the stereoscopic eyewear 200 that the viewer can open the menu or the like and input something only for the required item. Furthermore, it may be configured that the eyewear is partially provided with a seal on which a two-dimensional barcode storing individual data is applied, or a two-dimensional barcode printed on a warranty card or instruction manual is captured by the camera of the viewer detecting unit 101 and analyzed, in order to store in the viewer/stereoscopic eyewear database 102 as the individual data of the stereoscopic eyewear 200.
An example is explained above in which the registration buttons are provided on the remote controller. However, it may be configured that the display unit 109 displays a menu for registering the viewer and stereoscopic eyewear in response to the push of option button provided on the remote controller, in order to select each item and individually input the data.
FIG. 2 is a perspective view that shows a schematic configuration of the stereoscopic-image display apparatus 100 in the embodiment according to the present invention. The viewer H1 to viewer H3 are persons who want to view the displayed 3D image as the 3D image, when viewing the 3D image with the stereoscopic-image display apparatus 100. The viewer H4 is a person who wants only the 2D image for the displayed image, because the person cannot recognize the displayed 3D image as the 3D image. Among those persons, the viewer H1, viewer H2 and viewer H4 are adults, and the viewer H3 is a child.
Next, it will be described in detail about the operation of the viewer detecting unit 101. When the display unit 109 displays the 3D image, the viewer detecting unit 101 regularly captures viewer's image and extracts a captured person. In addition, when the source image obtained from the tuner unit 106 or external input unit 107 is the 3D image even in the case that the display unit 109 displays the 2D image, the viewer detecting unit 101 regularly captures viewer's image and extracts a captured person. When the source image obtained from the tuner unit 106 or external input unit 107 is the 2D image, the viewer detecting unit 101 neither captures viewers nor extracts persons because the stereoscopic eyewear 200 is not required.
The viewer detecting unit 101 detects whether or not the person extracted from the image obtained by capturing the viewer wears the registered stereoscopic eyewear 200. When the detection result for the stereoscopic eyewear 200 represents that no viewer wear the stereoscopic eyewear 200, the viewer detecting unit 101 notifies to the controlling unit 103 that no viewer utilize the stereoscopic eyewear 200. After receiving the notification from the viewer detecting unit 101, the controlling unit 103 instructs the image processing unit 108 to display the 2D image. Based on the instruction from the controlling unit 103, the image processing unit 108 makes the display unit 109 display any one of the right eye's image and left eye's image regarding the 3D image.
When there is a viewer wearing the stereoscopic eyewear 200, the viewer detecting unit 101 notifies to the controlling unit 103 about the presence of the viewer utilizing the stereoscopic eyewear 200 and instructs the controlling unit 103 to take out the image data for verifying the viewer and stereoscopic eyewear 200 from the viewer/stereoscopic eyewear database 102. After receiving the instruction from the viewer detecting unit 101, the controlling unit 103 instructs the image processing unit 108 to display the 3D image. Based on the instruction from the controlling unit 103, the image processing unit 108 makes the display unit 109 alternately display the right eye's image or left eye's image regarding the 3D image.
Then, the controlling unit 103 sequentially takes out the image data of the viewer, and the image data utilized for verifying the viewer and stereoscopic eyewear 200 registered in the viewer/stereoscopic eyewear database 102 in orders of registration number K and registration number G.
At first, the verification image data for the stereoscopic eyewear 200 is taken out in order of the registration number G, and sent to the viewer detecting unit 101. The viewer detecting unit 101 compares the verification image data of the stereoscopic eyewear 200 sent from the controlling unit 103 and the image data of the stereoscopic eyewear 200 captured by the camera of the viewer detecting unit 101, and identifies what the stereoscopic eyewear 200 is with the registration number G.
The stereoscopic eyewear 200 is previously provided with the mark portion for the individual selection, in order to perform the individual determination. As shown in FIG. 2, the camera of the viewer detecting unit 101 is arranged at an upper portion of the stereoscopic-image display apparatus 100 in order to capture the viewer H1 to viewer H4 viewing the display unit 109 from the front surface. It is possible to simultaneously capture the eyewear 1 to eyewear 4 worn by the viewer H1 to viewer H4, respectively, from the front surface.
FIGS. 3A to 3D are views for explaining an individual selection mark portion MK of the eyewear regarding the stereoscopic-image display apparatus 100 in the embodiment according to the present invention. FIG. 3A shows an example in which the individual selection mark portion MK is applied on the center portion of the eyewear's lens. FIG. 3B shows an example in which the individual selection mark portion MK is applied on the peripheral portion of the eyewear. FIG. 3C shows an example in which a triangle mark is applied as the individual selection mark portion MK on the side surface of the eyewear's frame, to distiguish each eyewear based on the frame shape when the frame portion of eyewear is seen from the front surface. FIG. 3D shows an example in which a rectangular mark is applied as the individual selection mark portion MK on the side surface of the eyewear's frame, to distinguish each eyewear based on the frame shape when the frame portion of eyewear is seen from the front surface.
When the comparison result represents that the verified eyewear is one of the registered stereoscopic eyewears 200, the viewer detecting unit 101 stores the registration number G of the stereoscopic eyewear 200 in a working memory.
Next, the image data for verifying the viewer is taken out in order of the registration number K, and sent to the viewer detecting unit 101. The viewer detecting unit 101 compares the viewers' verification image data sent from the controlling unit 103 with the viewers' image data captured by the camera of the viewer detecting unit 101, and identify who is the viewer having the registration number K.
When there are plural viewers, the above processing for identifying the stereoscopic eyewear 200 and viewer is repeated and the combination of the registration number K of viewer accepted from the view detecting unit 101 and registration number G of stereoscopic eyewear 200 are stored into the working memory. When the processing for identifying all viewers is completed, the viewer detecting unit 101 gives the information about the combination of the registration number K of viewer and registration number G of stereoscopic eyewear 200 to the controlling unit 103. Based on the given information about the combination of the registration number K of viewer and registration number G of stereoscopic eyewear 200, the controlling unit 103 invokes individual data regarding the mode selection corresponding to the registration number K of the viewer identified by the viewer/stereoscopic eyewear database 102, determines whether the set mode selection represents to select the 3D mode or 2D mode, and makes the sending unit 105 send the control signal to the corresponding stereoscopic eyewear 200. The control signal is superimposed on the synchronizing signal and then sent to the corresponding stereoscopic eyewear 200.
FIG. 4 is a view for explaining the timings of sending the synchronizing signal and control signal in the stereoscopic-image display apparatus 100 of the embodiment according to the present invention.
FIG. 4(a) shows the display timing for the display image signal of the 3D image displayed on the display unit 109. The display unit 109 alternately displays the right eye's image signal and left eye's image signal. FIG. 4(b) shows the synchronizing signal synchronized with the display image signal. The synchronizing signal becomes H when the right eye's signal is displayed on the display unit 109, and becomes L when the left eye's signal is displayed on the display unit 109. The control signal is sent after superimposed on the synchronizing signal described above. In the example shown in the figure, the period for sending the control signal is included in one cycle in which the right eye's image and left eye's image are displayed. The sending period may be based on plural cycles, instead of one cycle. FIG. 4(c) shows the signal utilized for controlling the shutter's open/close state and sent from the synchronizing circuit 202 to the right eye's shutter 204. When the synchronizing signal becomes H, the shutter is open and the viewer's right eye can see the right eye's image. When the synchronizing signal becomes L, the shutter is closed and the viewer's right eye cannot see the left eye's image. FIG. 4(d) shows the signal utilized for controlling the shutter's open/close state and sent from the synchronizing circuit 202 to the left eye's shutter 205. When the synchronizing signal becomes H, the shutter is open and the viewer's left eye can see the left eye's image. When the synchronizing signal becomes L, the shutter is closed and the viewer's left eye cannot see the right eye's image.
Based on the synchronizing circuit 202 of the stereoscopic eyewear 200, the mode change is performed to set a mode utilized for viewing the 3D image or a mode utilized for viewing the 2D image.
When the mode utilized for viewing the 3D mode is set, the synchronizing circuit 202 of the stereoscopic eyewear 200 controls the open/close timing of the right eye's shutter 204 utilized for viewing the right eye's image and left eye's shutter 205 utilized for viewing the left eye's image, in synchronization with the synchronizing signal received by the receiving unit 201. It is configured to perform the open/close operations for the right eye's shutter 204 and left eye's shutter 205 in accordance with the received synchronizing signal during the time when the synchronizing signal is continuously received. It is configured to keep the synchronizing signal being received before the control signal sending period and to make the synchronizing signal be self-propelled during the control signal sending period when the synchronizing signal is included in the control signal, because the synchronizing signal cannot be obtained.
It may be configured that the display unit 109 displays the image data of the viewer and stereoscopic eyewear 200 captured by the camera of the viewer detecting unit 101, with a message indicating “not registered yet, register soon” or the like for urging the registration, when a viewer and stereoscopic eyewear 200 not registered in the viewer/stereoscopic eyewear database 102 are detected. The notification to the non-registered viewer may be implemented by the display of icon on a part of the display unit 109. Alternatively, it may be configured that no notification is performed for the non-registered viewer and non-registered stereoscopic eyewear 200.
FIGS. 5A to 5C are views for explaining the wear/non-wear detecting unit 206 of the eyewear regarding the stereoscopic eyewear 200 of the embodiment according to the present invention.

FIG. 5C shows an example in which the wear/non-wear detecting unit 206 is arranged on the frame of the stereoscopic eyewear 200 where the viewer's ear contacts with, i.e., the frame's portion where the frame rests on the ear. In that example, it detects whether or not electric current flows in a small push switch or detects the electric capacitance with a sensor provided for detecting the wear/not-wear condition, to determine whether the viewer does or does not wear the stereoscopic eyewear 200.
The wear/non-wear detecting unit 206 is configured as shown in FIGS. 5A to 5C. Thus, when the viewer wears the stereoscopic eyewear 200, the wear/non-wear detecting unit 206 detects that the viewer wears the stereoscopic eyewear 200 and then the power is supplied to each circuit of the stereoscopic eyewear 200. Based on the default setting, the start-up is performed on the stereoscopic eyewear 200 with the 3D mode utilized for viewing the 3D image. When it is detected that the viewer does not wear the stereoscopic eyewear 200, the power supply to each circuit of the stereoscopic eyewear 200 is stopped.
Assume the case that the viewers H1-H4 wear the eyewears 1-4 configured with the stereoscopic eyewear 200 according to the present invention when the stereoscopic-image display apparatus 100 according to the present invention displays the 3D image. In the assumption, the viewers H1-H3 can view the displayed 3D image as the 3D image based on the individual data, and the viewer 114 wearing the eyewear 4 can view the displayed 3D image as the 2D image based on the individual data.
As described above, the stereoscopic-image display apparatus 100 can automatically send the instruction for changing the 3D/2D modes to the stereoscopic eyewear 200 in accordance with the request of the viewer who views the 3D image. Therefore, the viewer who cannot view the 3D image and/or does not want to view the 3D image is able to view and enjoy the 2D image, even when other viewers are viewing the 3D image. In addition, the viewer who cannot view the 3D image and/or does not want to view the 3D image does not need to select the 2D image display after wearing the stereoscopic eyewear 200 at each time when the 3D image is displayed. Thus, the viewer who cannot view the 3D image and/or does not request to view the 3D image can comfortably view and enjoy the 2D image. Furthermore, in a case of no viewer wanting to view the 3D image with the stereoscopic-image display apparatus 100 according to the present invention wearing the stereoscopic eyewear 200, and in a case of all viewers wearing the stereoscopic eyewear 200 having a request to view the 2D image, the stereoscopic-image display apparatus 100 outputs any one of both right eye's image and left eye's image regarding the 3D image to the display unit 109. Therefore, the viewer can comfortably view the 2D image without wearing the stereoscopic eyewear 200, and it is very convenient.
The embodiment described above is merely an example, and the present invention is not necessarily limited to the example. For example, the stereoscopic-image display apparatus and stereoscopic eyewear is explained in the embodiment. However, the present invention is not limited to the stereoscopic-image display apparatus and stereoscopic eyewear. It is enough to output the 3D image signal and synchronizing signal, receive the synchronizing signal, and display the stereoscopic image to the viewer with an eyewear utilized for viewing the stereoscopic image.

The registration number K is utilized for identifying the viewer who views the image displayed on the display unit 109 of the stereoscopic-image display apparatus 100. The registration number K is the primary key of the viewer table 1T.
The viewer's image is captured by the camera of the viewer detecting unit (detecting unit) 101. It is enough to store the image data of the viewer in the viewer/stereoscopic eyewear database 102, and thus it is not necessarily required to store the image data of the viewer in the viewer table T1. At that time, address or path regarding the image data of the viewer is stored in the column of the viewer's image.
The mode is information regarding the viewer's selection for viewing as the 2D image or 3D image when the image processing unit 108 detects that the image of the broadcast program received by the tuner unit 106 or the source image obtained by the external input unit 107 is the 3D image. For example, when the viewer requests to view the displayed 3D image as the 2D image, the character column representing the 2D is stored as the mode. On the other hand, when the viewer requests to view the displayed 3D image as the 3D image, the character column representing the 3D is stored as the mode. The viewing of the displayed 3D image as the 2D image means to view the right eye's image or left eye's image regarding the 3D image.
The name is the viewer's name.
When plural viewers are registered in the viewer table 1T, the priority represents the priority order for the viewers based on the mode. When the viewer detecting unit 101 detects the plural viewers, the stereoscopic-image display apparatus 100 makes the display unit 109 display the image corresponding to the mode of the viewer having the highest priority. The viewer whose priority is higher means the viewer whose priority is the highest of the plural viewers detected by the viewer detecting unit 101. For example, the priority is configured with numerals and the viewer having a stronger authority stores a smaller numeral in the priority. The same numeral is not set for different viewers as the priority.
Alternatively, the viewer having a stronger authority may store a larger numeral in the priority.

Secondly, it will be described about the operation in the case that the stereoscopic eyewear 200 having the higher priority is identified and the display unit 109 displays the image of mode corresponding to the viewer who wears the identified stereoscopic eyewear 200.
FIG. 13 is a flowchart that shows an example of a procedure performed by the controlling unit 103. The procedure shown in FIG. 13 identifies the viewer based on the priority and identifies the mode selected by the identified viewer.
When the image of the broadcast program received by the tuner unit 106 or source image obtained by the external input unit 107 is the 3D image, the controlling unit 103 makes the viewer detecting unit 101 regularly capture plural viewers and extract plural viewers from the captured image (step S101). Based on the image of each extracted viewer, the controlling unit 103 searches the priority and mode of the viewer corresponding to the viewer's image in the viewer table 1T (step S102).
At the step S102, the controlling unit 103 verifies whether or not the viewer in the viewer's image captured by the viewer detecting unit 101 is identical to the viewer in the viewer's image stored in the viewer's image column of the viewer table 1T. When the verification result represents that the viewers are identical, the controlling unit 103 extracts the viewer's priority and mode from the record of the viewer table 1T corresponding to the viewer captured by the viewer detecting unit 101.
The controlling unit 103 identifies the viewer having the highest priority of the extracted plural viewers (step S103). The controlling unit 103 determines whether or not the identified viewer having the highest priority wears the stereoscopic eyewear 200 (step S104). When having determined that the identified viewer having the highest priority does not wear the stereoscopic eyewear 200 (step S104: NO), the controlling unit 103 proceeds the procedure to the step S106.
When having determined that the identified viewer having the highest priority wears the stereoscopic eyewear 200 (step S104: YES), the controlling unit 103 determines whether the mode for the identified viewer having the highest priority is the 2D or not (step S105). When having determined that the mode for the identified viewer having the highest priority is the 2D (step S105: YES), the controlling unit 103 instructs the image processing unit 108 to output any one of the image signals regarding the right eye's image and left eye's image of the 3D image toward the display unit 109 (step S106). In addition, the controlling unit 103 sets the 2D mode in the control signal sent to the stereoscopic eyewear 200 (step S107). The controlling unit 103 superimposes the set control signal onto the synchronizing signal, outputs the superimposed synchronizing signal to the sending unit 105 (step S108) and ends the procedure.
When having determined that the mode for the identified viewer having the highest priority is not the 2D (step S105: NO), the controlling unit 103 instructs the image processing unit 108 to output the image signal regarding the 3D image to the display unit 109 (step S109). In addition, the controlling unit 103 sets the 3D mode in the control signal sent to the stereoscopic eyewear 200 (step S110). The controlling unit 103 superimposes the set control signal onto the synchronizing signal, outputs the superimposed synchronizing signal to the sending unit 105 (step S111) and ends the procedure.
Although the controlling unit 103 is described as the main processing unit in the above flow, it may be configured that the viewer detecting unit 101 works as the main processing unit.
The sending unit 105 of the stereoscopic-image display apparatus 100 receives the synchronizing signal on which the control signal is superimposed from the controlling unit, and sends the received synchronizing signal to the stereoscopic eyewear 200.
The receiving unit 201 of the stereoscopic eyewear 200 receives the synchronizing signal on which the control signal is superimposed from the sending unit 105, and separates into the synchronizing signal and control signal. The receiving unit 201 sends the separated control signal to the controlling unit 203, and sends the separated synchronizing signal to the synchronizing circuit 202. When the received control signal is the 2D mode, the controlling unit 203 instructs the synchronizing circuit 202 to synchronize with any one of the synchronizing signals regarding the right eye's image and left eye's image and to open the right eye's shutter 204 and left eye's shutter 205. Alternatively, the controlling unit 203 may turn off the power of the stereoscopic eyewear 200 when the control signal is 2D mode.
On the other hand, when the control signal is the 3D mode, the controlling unit 203 instructs the synchronizing circuit 202 to synchronize with the synchronizing signal and to alternately open and close the right eye's shutter 204 and left eye's shutter 205.
FIG. 14 is a flowchart that shows an example of a procedure performed by the controlling unit 103. The procedure of FIG. 14 identifies the stereoscopic eyewear 200 based on the priority, identifies the viewer who wears the identified stereoscopic eyewear 200 and identifies the mode selected by the identified viewer. It should be noted that the procedure of FIG. 14 is described in the case that all viewers wear the stereoscopic eyewear 200.
When the image of the broadcast received by the tuner unit 106 or source image obtained by the external input unit 107 is the 3D image, the controlling unit 103 makes the viewer detecting unit 101 regularly capture plural viewers and extract plural viewers from the captured image (step S201).
The controlling unit 103 extracts the image of the stereoscopic eyewear 200 worn by the viewer from the plural extracted viewer's images (step S202). Based on the extracted image of the stereoscopic eyewear 200, the controlling unit 103 searches the priority in the eyewear table 2T (step S203).
At the step S203, the controlling unit 103 verifies whether or not the stereoscopic eyewear 200 extracted from the image captured by the viewer detecting unit 101 is identical to the stereoscopic eyewear 200 stored in the eyewear's image column of the eyewear table 2T. When the verification result represents that the stereoscopic eyewears 200 shown in both images are identical, the controlling unit 103 extracts the priority of the stereoscopic eyewear 200 from the record of the eyewear table 2T corresponding to the stereoscopic eyewear 200 captured by the viewer detecting unit 101.
At the step S203, the controlling unit 103 may utilize the mark position of the eyewear table 2T for the verification described above. In the case that the position of the individual selection mark portion MK on the stereoscopic eyewear 200 is previously known, it is possible to perform faster the verification with the image of the extracted stereoscopic eyewear 200 and eyewear's image of the eyewear table 2T.
The controlling unit 103 identifies the stereoscopic eyewear 200 having the highest priority of the searched plural stereoscopic eyewears 200 (step S204). The controlling unit 103 searches the viewer who wears the identified stereoscopic eyewear 200 in the view table 1T, based on the captured image, and identifies the searched viewer and the mode for the identified viewer (step S205).
The procedure after the step S206 is similar to the procedure after the step S105 of FIG. 13, and the explanation for the procedure after the step S206 is omitted.
Although the controlling unit 103 is described as the main processing unit in the above flow, it may be configured that the viewer detecting unit 101 works as the main processing unit.
It may be configured that the viewer table 1T includes a weighting column based on the viewer. For example, the weighting is based on the viewer's age, viewer's viewing time or the like. When the viewer's attribute is registered in the viewer table 1T, the weighting based on the viewer is registered. Then, when the viewer is identified, the new priority in which the weighting has been applied is utilized for identifying the viewer. The stereoscopic-image display apparatus 100 may refer the mode corresponding to the viewer identified with the new priority to perform the change processing between the 2D image and 3D image for the image displayed on the display unit 109.
When the viewer having the higher priority wears the stereoscopic eyewear 200, the stereoscopic-image display apparatus 100 makes the display unit 109 display the image corresponding to the mode selected by the viewer having the higher priority. Therefore, the stereoscopic-image display apparatus 100 can automatically display any one of the 2D image and 3D image on the display unit 109, when the modes selected by the plural viewers are different from each other.
In addition, when the viewer having the stronger authority wears the stereoscopic eyewear 200 having the higher priority, the stereoscopic-image display apparatus 100 can lead the similar advantage as described above.
The stereoscopic-image display apparatus 100 can prevent the conflict for selecting the 2D image display or 3D image display among the plural viewers, although such an argument is similar to the conflict over which program to view. In the case that the priority for the viewer having the decisive power is set higher, the stereoscopic-image display apparatus 100 can prevent the argument for selecting the display mode because of automatically displaying the image based on the mode corresponding to the viewer having the higher priority. For example, additionally assume the case that plural viewers being the parent and child view the image. When the parent's priority is set higher or when the parent wears the stereoscopic eyewear 200 having the higher priority, the stereoscopic-image display apparatus 100 can prevent the child from viewing the 3D image for a longer period of time.
When the viewer having the higher priority does not wear the stereoscopic eyewear 200, the stereoscopic-image display apparatus 100 displays any one of the right eye's image and left eye's image regarding the 3D image on the display unit 109. Therefore, the stereoscopic-image display apparatus 100 can display the 2D image based on the selection of the viewer having the stronger authority on the display unit 109, even when there are plural viewers.
The embodiment 2 is as described above. The other things about the embodiment 2 are similar to the embodiment 1, and thus provided with the same reference numerals for the corresponding portions, and the detailed explanation about the other things is omitted.
Embodiment 3
The embodiment 3 relates to an example in which the viewer who wears the stereoscopic eyewear 200 having the highest priority is identified and the display unit 109 displays the image based on the mode corresponding to the identified viewer, when the priorities set for the plural viewers are the same.
FIG. 15 is a view showing another example of the record layout in the viewer table 1T. The priority of the viewer table 1T in the embodiment 3 can store the same priority for different viewers. For example, the priority of Taro whose registration number K=1 and priority of Hanako whose registration number K=4 are 1, in FIG. 15. On the other hand, the eyewear table 2T in the embodiment 3 stores the different priority for the different stereoscopic eyewear 200, similarly to the eyewear table 2T of FIG. 8 (see FIG. 8).
Assume the case that viewers, who are registered in the viewer table 1T of FIG. 15 and respectively have the registration numbers K=1, 2, 3, 4, view the image displayed on the display unit 109 of the stereoscopic-image display apparatus 10, together. In addition, assume the case that the viewers having the registration numbers K=1, 2, 3, 4 respectively wear the stereoscopic eyewears 200 having the registration numbers G=1, 2, 3, 4 mentioned in FIG. 8.
Taro having the registration number K=1 and Hanako having the registration number K=4 both have the priority being 1. However, the stereoscopic eyewear 200 having the registration number G=4 and worn by Hanako has the priority being 4, although the stereoscopic eyewear 200 having the registration number G=1 and worn by Taro has the priority being 1. Thus, the stereoscopic eyewear 200 worn by Taro has the higher priority than the stereoscopic eyewear 200 worn by Hanako.
In addition, the Taro's mode is the 2D and the Hanako's mode is the 3D (see FIG. 15). Thus, when the image of the broadcast program selected by the tuner unit 106 or the source image obtained by the external input unit 107 is the 3D image, the stereoscopic-image display apparatus 100 forcibly makes the display unit 109 display the image based on the 2D mode that has been previously selected by Taro. Anyway, the image based on the 2D mode is the right eye's image or left eye's image regarding the 3D image.
FIG. 16 is a flowchart that shows another example of the procedure performed by the controlling unit 103.
When the image of the broadcast program received by the tuner unit 106 or the source image obtained by the external input unit 107 is the 3D image, the controlling unit 103 makes the viewer detecting unit 101 regularly capture plural viewers and extract plural viewers from the captured images (step S301). Based on the each image of the extracted plural viewers, the controlling unit 103 searches the priority and mode for the viewer corresponding to the viewer's image from the viewer table 1T (step S302).
The controlling unit 103 identifies the viewer having the highest priority of the extracted plural viewers (step S303). The controlling unit 103 determines whether the step S303 has identified plural viewers or not (step S304). When having determined that the step S303 has not identified plural viewers (step S304: NO), the controlling unit 103 decides the mode corresponding to the identified singular viewer as the mode utilized for the image displayed on the display unit 109 (step S305). Then, the controlling unit 103 proceeds the procedure to the step S310.
When having determined that the step S303 has identified plural viewers (step S304: YES), the controlling unit 103 extracts the image of the stereoscopic eyewear 200 worn by each viewer from the image of the identified plural viewers (step S306). Based on the each image of the extracted stereoscopic eyewears 200, the controlling unit 103 searches the priority in the eyewear table 2T (step S307).
The controlling unit 103 identifies the stereoscopic eyewear 200 having the highest priority based on the searched result (step S308). The controlling unit 103 decides that the mode for the viewer wearing the identified stereoscopic eyewear 200 as the mode utilized for the image displayed on the display unit 109 (step S309).
The procedure after the step S310 is the same as the procedure after the step S105 shown in FIG. 13, and the explanation is omitted. In addition, the flow after the step S310 is omitted in FIG. 16.
Although the controlling unit 103 is described as the main processing unit in the above flow, it may be configured that the viewer detecting unit 101 works as the main processing unit.
In the explanation described above, plural viewers having the same priority are firstly identified and the stereoscopic eyewear 200 is secondly identified. However, the sequence may be reversed. Particularly, it may be configured that plural stereoscopic eyewears 200 having the same priority are firstly identified and the viewer is secondly identified. In that configuration, it should make the priority of the eyewear table 2T be able to set the same priority for different stereoscopic eyewears 200, and should make the priority of the viewer table 1T be unable to set the same priority for different viewers.
The controlling unit 103 extracts the image of plural stereoscopic eyewears 200 from the image captured by the viewer detecting unit 101, and searches the priority in the eyewear table 2T based on the extracted image. When plural stereoscopic eyewears 200 have the highest priority, the controlling unit 103 extracts the image for each viewer wearing the stereoscopic eyewear 200. Based on the extracted image of each viewer, the controlling unit 103 searches the priority and mode in the viewer table 1T. The controlling unit 103 decides the mode corresponding to the viewer having the highest priority based on the searched result as the mode utilized for the image displayed on the display unit 109.
The stereoscopic-image display apparatus 100 can prevent the conflict regarding the display mode, even in the case that plural viewers have the same priority regarding the mode selection.
When the viewers have the same priority, the stereoscopic-image display apparatus 100 decides the mode utilized for the image displayed on the display unit 109, based on the priority set for the stereoscopic eyewear 200 worn by each viewer. Thus, it is possible to automatically decide the mode utilized for the image displayed on the display unit 109, in the case that the viewer having the higher priority wears the stereoscopic eyewear 200 having the higher priority. Therefore, the stereoscopic-image display apparatus 100 is convenient for the viewers.
The embodiment 3 is as described above. The other things about the embodiment 3 are similar to the embodiments 1 and 2, and thus provided with the same reference numerals for the corresponding portions, and the detailed explanation about the other things is omitted.
