Description

  The present invention relates to a stereoscopic image display device and stereoscopic glasses for managing viewing time for each observer when a plurality of observers observe a stereoscopic (3D) image.

  In recent years, 3D images that have begun to spread are produced based on binocular parallax technology. For example, Non-Patent Document 1 describes a technical explanation regarding 3D images and safety standards regarding 3D images. A person recognizes image signals from two viewpoints of the right eye and the left eye to determine whether the subject is three-dimensional. The distance between a person's right eye and left eye is about 5-7 cm away from a child to an adult. For this reason, the images entering the left and right eyes differ by the difference in the viewpoint of the observer. The difference increases when the distance to the subject is short and decreases when the distance is long. The brain uses the binocular parallax as a clue to perceive whether or not the subject is solid.

  A person can make an image feel the depth by giving images with different viewpoints to the right eye and the left eye independently. A 3D display using binocular parallax uses 3D glasses such as a liquid crystal shutter and independently and periodically gives images to the right and left eyes. For example, when a right-eye image and a left-eye image are sequentially displayed on the display of this principle, the image displayed on the display has a stereoscopic effect and can be perceived as a stereoscopic image that protrudes forward and backward with respect to the display surface. Further, when the parallax is increased, the pop-out amount and the retraction amount are increased, and it is possible to give a surprise and impression to an observer who is viewing an image using 3D glasses such as a liquid crystal shutter.

  Also, 3D glasses for 3DTV are commercially available with a changeover switch for switching from a 3D image to a 2D image. When an observer who wears these 3D glasses and sees a 3D image becomes tired, he or she doubles the switch to forcibly switch the viewed 3D image to a 2D image. Can do. In glasses with liquid crystal shutters used in 3D TVs that display images for the right eye and left eye alternately, when the switch is pressed and switching to 2D images is selected, the liquid crystal shutters for the left eye and right eye, respectively. The shutter is opened at either the timing when the image for the right eye is displayed or the timing when the image for the left eye is displayed, and the same image for either the right eye or the left eye is viewed with both eyes It will be.

  Patent Document 1 discloses a stereoscopic display gaming machine that forcibly switches a stereoscopic image to a normal flat image when an allowable gaming time for stereoscopic viewing has elapsed. FIG. 6 is a flowchart thereof.

  Further, in Patent Document 2, when the accumulated value of the stereoscopic intensity of the stereoscopic image accumulated over the display time when the stereoscopic image is displayed exceeds the accumulated stereoscopic intensity threshold L, the 3D image is changed to the 2D image. A stereoscopic image display device for switching is introduced.

  FIG. 7 is a graph showing an outline of a change in the cumulative stereoscopic intensity of the stereoscopic image with respect to the time since the display of the stereoscopic image is started, the cumulative stereoscopic intensity threshold L, and the relationship between the displayed images. t1 is the display start time of the stereoscopic image, and is the start time when the observer observes the stereoscopic image. When the display of the stereoscopic image is started, it is checked whether or not the stereoscopic image is displayed every predetermined time. When the stereoscopic image is displayed, the level value of the stereoscopic strength of the stereoscopic image is set to the cumulative stereoscopic strength. to add. From t1 to t2, the level value of the three-dimensional intensity is added to the accumulated three-dimensional intensity in a stepped manner over time at every predetermined time. When the level value of the solid intensity is constant, the increment value added is also constant. In FIG. 7, the level value of the three-dimensional intensity changes at t2. At t3, the cumulative stereoscopic strength reaches the cumulative stereoscopic strength threshold L, the continuous display restriction of the stereoscopic image is started, and a warning message and a “2D” button for switching to the 2D image are displayed on the display unit. Until the “2D” button is pressed, the level value of the stereoscopic strength is added to the cumulative stereoscopic strength. When the “2D” button is pressed at t4, the cumulative stereoscopic strength is reset and the 2D image is switched. Thereafter, after a predetermined time has elapsed, a message notifying that display of the 3D image is possible and a “3D” button for switching to the 3D image are displayed. At t5, the “3D” button is pressed, and the operation of adding the level value of the solid strength to the cumulative solid strength every predetermined time is started again. The cumulative solid intensity in FIG. 7 explains the case where the solid intensity level value is added stepwise every predetermined time, but it is described that a constant increment may always be maintained like a proportional line. Has been.

Japanese Patent Laid-Open No. 7-16351 JP 2004-334833 A

However, viewing a 3D image continuously for a long time causes eye strain and becomes uncomfortable or causes a headache. When a plurality of people watch the same program at the same time, when all of them start watching the same 3D program at the same timing, the same observation time is required. The display device may forcibly switch the display of the 3D image to the 2D image after a predetermined time has elapsed from the start of the program. Further, as in Patent Document 2, 3D display may be performed until the cumulative solid strength exceeds the cumulative solid strength threshold L, and the continuous display restriction may be started from the time when the cumulative solid strength threshold L is exceeded.
However, a plurality of viewers watching the same program do not necessarily start watching the program at the same time.

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

  FIG. 1 is a functional block diagram showing a main part configuration of a stereoscopic image display apparatus 100 according to an embodiment, and a functional block diagram showing a main part configuration of stereoscopic glasses 200.

  The stereoscopic image display apparatus 100 stores the observer and the observer detection unit 101 for specifying the stereoscopic glasses 200 worn by the observer, and individual data of the observer and the stereoscopic glasses 200. And a viewer and a stereoscopic eyeglass database 102 to be managed, a control unit 103, and a timer for measuring the time during which the observer detected by the observer detection unit 101 continuously views 3D images is set for each observer. A timer individual management unit 104 for managing the image, a synchronization signal synchronized with the display timing of the right-eye image and the left-eye image of the 3D image, a control signal for switching the observation mode of the stereoscopic glasses 200 between the 3D mode and the 2D mode, and the like. Transmitter 105 for transmitting to stereoscopic glasses 200, tuner 106 for receiving broadcast waves, and external input for connecting an input signal from the outside. And a section 107.

  The stereoscopic glasses 200 receives the synchronization signal and the control signal from the stereoscopic image display device 100, and receives the synchronization signal separated by the reception unit 201. The synchronization circuit 202, the control unit 203 that receives the control signal separated by the receiving unit 201, the right-eye shutter 204 for viewing the right-eye image of the 3D image, and the left-eye for viewing the left-eye image of the 3D image The shutter 205 for use, the attachment / detachment detection unit 206 for detecting whether the observer wears or removes glasses, and that the stereoscopic image continuous viewing limit time has elapsed or that the predetermined time is before the stereoscopic image continuous viewing limit time. It is comprised from the alerting | reporting part 207 for alerting | reporting. The glasses 1, glasses 2 to glasses n-1 are stereoscopic glasses having the same configuration as that of the stereoscopic glasses 200.

  A broadcast program received by the tuner unit 106 of the stereoscopic image display apparatus 100 is detected by the image processing unit 108 as a program including a 3D image or a program including a 2D image, is subjected to image processing, and is transmitted from the control unit 103. Accordingly, the 3D image or 2D image is displayed on the display unit 109. When the broadcast program being received is a 2D image, it is not necessary to send a synchronization signal from the transmission unit 105 to the stereoscopic glasses 200, so the transmission of the synchronization signal from the control unit 103 to the transmission unit 105 is stopped or maintained. Instruct. When the broadcast program being received is a 3D image, the control unit 103 instructs the transmission unit 105 to start or maintain transmission of the synchronization signal.

  Similarly, the case where the source image displayed on the display unit 109 is the external input unit 107 will be described. When the source image is not a broadcast program from the tuner unit 106 but a source image from another video device, such as a BD / DVD player or a CATV tuner, the image processing unit 108 can select a source image including a 3D image or only a 2D image. Detect if source image. In the case of a 3D image, the image is processed, the 3D image is displayed on the display unit 109 in accordance with the transmission timing from the control unit 103, and an instruction to start transmission maintenance or to maintain transmission to the transmission unit 105 is similarly performed. . In the case of a source image of only a 2D image, the source image itself input to the external input unit 107 is displayed on the display unit 109, and the transmission unit 105 stops transmission or stops when a synchronization signal is transmitted. Instruct.

  In addition, the image processing unit 108 notifies the control unit 103 whether the source image is a 3D image or a 2D image. The notification is performed at the timing of source image switching or broadcast program switching. The external input 107 is also performed when content such as DVD or BD is switched.

  Furthermore, the stereoscopic image display device 100 is provided with an observer detection unit 101 for detecting an observer who is observing the 3D image or 2D image displayed on the display unit 109. The observer detection unit 101 also detects the stereoscopic glasses 200 worn by the observer. The observer detection unit 101 includes a camera for photographing the observer's face and stereoscopic glasses 200 as image data, an image coding circuit for coding the photographed image data into a specific compressed image, and coding work. For example. The stereoscopic image display apparatus 100 uses the observer detection unit 101 to photograph the image data of the face of the observer who uses the apparatus for the first time, and uses the observer and stereoscopic vision image data for individually determining the observer. Store in the glasses database 102.

Although not shown, the stereoscopic image display apparatus 100 includes an observer using the apparatus and an observer registration unit and an eyeglass registration unit for registering the stereoscopic glasses 200 used in the apparatus. For example, a registration button for registering the observer or the stereoscopic glasses 200 may be prepared on a remote controller or the like. When the registration button is pressed, a selection screen of “observer registration”, “stereoscopic glasses registration”, “observer and stereoscopic glasses registration” and “return” is displayed on the display unit 109. . The observer goes to the front of the observer detection unit 101 of the stereoscopic image display device 100 with the stereoscopic glasses 200 attached, and after pressing the registration button, selects any registration item with the remote control. When the “return” button is pressed, the registration-related processing is interrupted and the initial state is restored. When a button other than the “Return” button is pressed, the camera of the observer detection unit 101 takes registration image data of an appropriate size while zooming up the subject such as the observer or the stereoscopic glasses 200.
Here, when “observer registration” is selected, the observer detection unit 101 detects a human being in the image captured by the camera so that the entire person is displayed. Zoom and take an image. Alternatively, the face portion may be extracted and photographed. Furthermore, you may make it image | photograph the upper body part. Furthermore, an image having an arbitrary size designated by the observer may be taken.
If “stereoscopic eyeglass registration” is selected, the observer detection unit 101 detects the face of the observer in the image captured by the camera and is attached to the face. While zooming in on the portion of the stereoscopic glasses 200, registration image data of an appropriate size of the stereoscopic glasses is taken.
Further, when “Register both observer and stereoscopic glasses” is selected, both operations when “observer registration” and “stereoscopic glasses registration” are selected are performed. Are performed sequentially. Since there is no priority order, either may be performed first.

  The captured image data is provisionally stored in the encoding work memory as an image file compressed by a predetermined image compression encoding. The image data stored in the encoding memory is displayed on the display unit 109, and confirms with the observer whether or not the image data can be registered in the observer and stereoscopic vision database. If the observer gives consent, the image data displayed on the display unit 109 is displayed as “observer registration” image data or “stereoscopic eyeglass registration” image data by the control unit 103. Stored in a predetermined area of the eyeglass database 102. The image compression encoding method used for the registration image data may be any encoding method such as JPEG, TIFF, GIF, or PDF.

  In the above description, the method of registering the observer and the stereoscopic glasses 200 with the observer wearing the stereoscopic glasses 200 has been described. However, the observer and the stereoscopic glasses 200 are registered separately. When searching for an observer observing the stereoscopic image display device 100, the image data of the observer who is not wearing the stereoscopic glasses 200 and the image data of the stereoscopic glasses 200 are combined, Search data may be created.

  Furthermore, the observer registration means and the eyeglass registration means not only register the image data of the observer and the stereoscopic eyeglasses 200 but also the observer and other individual data of the stereoscopic eyeglasses 200. A menu-type interface may be prepared for input. For example, as individual data of the observer, in addition to the image data of the observer, an observer registration number for managing the registered observer data, the image is displayed in either the 3D mode or the 2D mode. Items such as mode selection, name, age, stereoscopic image continuous viewing time limit, continuous break time, etc. for selecting whether or not to view the video. The individual data of the stereoscopic glasses 200 includes items such as a stereoscopic glasses registration number and a mark position for managing the registered stereoscopic glasses data in addition to the image data of the stereoscopic glasses 200. Conceivable. Regarding the individual data of the stereoscopic glasses 200, the observer may open a menu or the like and input only necessary items. In addition, a 2D barcode storing individual data is attached to a part of the glasses with a sticker or the like, or a 2D barcode printed on a warranty card or an instruction manual is captured by the camera of the observer detection unit 101. Thus, the data may be analyzed and taken into the observer and stereoscopic vision database 102 as individual data of the stereoscopic vision glasses 200.

  Heretofore, an example in which a registration button is provided on the remote control has been described. However, when an option button or the like on the remote control is pressed, a menu for registering an observer or stereoscopic glasses is displayed on the display unit 109. It is also possible to select each item so that data can be individually input.

  FIG. 2 is a perspective view illustrating a schematic configuration of the stereoscopic image display apparatus 100 according to the embodiment of the present invention. The observer H1 to the observer H3 are persons who desire to view the displayed 3D image as it is as a 3D image when observing the 3D image on the stereoscopic image display device 100. Further, the observer H4 is a person who desires only a 2D image as a display image because the 3D image cannot be recognized as a 3D image. Among these, the observer H1, the observer H2, and the observer H4 are adults, and the observer H3 is a child.

  Next, the operation of the observer detection unit 101 will be described in detail. When a 3D image is displayed on the display unit 109, the observer detection unit 101 periodically captures an image of the observer and extracts the person being photographed. Even when a 2D image is displayed on the display unit 109, if the source image from the tuner unit 106 or the external input unit 107 is a 3D image, an image of the observer is periodically captured and captured. The person who is. Note that when the source image itself from the tuner unit 106 or the external input unit 107 is a 2D image, the stereoscopic glasses 200 are not required, and thus the observer's shooting and person extraction operations are not performed.

The observer detection unit 101 detects whether or not the person extracted from the image obtained by photographing the observer is wearing the registered stereoscopic glasses 200. As a result of detecting the wearing of the stereoscopic glasses 200, when it is determined that all the viewers are not wearing the stereoscopic glasses 200, the observer detection unit 101 instructs the control unit 103 to provide the stereoscopic glasses. Notify that there is no observer using 200. The control unit 103 receives the notification from the observer detection unit 101 and instructs the image processing unit 108 to display a 2D image. In response to an instruction from the control unit 103, the image processing unit 108 displays either the right-eye image or the left-eye image of the 3D image on the display unit 109.
When there is an observer wearing the stereoscopic glasses 200, the observer detection unit 101 notifies the control unit 103 that there is an observer using the stereoscopic glasses 200. Then, an instruction is given to take out image data for verification of the observer and the stereoscopic glasses 200 from the observer and stereoscopic glasses database 102. The control unit 103 receives an instruction from the observer detection unit 101 and instructs the image processing unit 108 to display a 3D image. The image processing unit 108 displays the right-eye image or the left-eye image of the 3D image alternately on the display unit 109 according to an instruction from the control unit 103.

  Subsequently, the control unit 103 uses the observer registration number or the stereoscopic glasses registration number as the verification image data of the observer and the stereoscopic glasses 200 registered in the observer and stereoscopic glasses database 102. Take out in order.

  First, the image data for verification of the stereoscopic glasses 200 is extracted in the order of the stereoscopic glasses registration numbers and sent to the observer detection unit 101. The observer detection unit 101 compares the image data for verification of the stereoscopic glasses 200 from the control unit 103 with the image data of the stereoscopic glasses 200 taken by the camera of the observer detection unit 101, and registers stereoscopic glasses. The number of the stereoscopic glasses 200 of the number is specified.

  In addition, in order to perform individual determination, the stereoscopic glasses 200 are prepared and registered in advance with individual selection mark portions attached. As shown in FIG. 2, the camera of the observer detection unit 101 is installed at an upper position of the stereoscopic image display device 100 and can photograph the observer H4 from the observer H1 who is looking at the display unit 109 from the front. It is like that. The glasses 1 to 4 worn by the observers H1 to H4 can also be photographed simultaneously from the front.

  The timer individual management unit 104 manages a timer for measuring the time during which the observer detected by the observer detection unit 101 continuously views 3D images for each of the observers H1 to H4. . The observer detecting unit 101 can detect the glasses 4 from the glasses 1 having the same configuration as the stereoscopic glasses 200 used by the observer H1 to the observer H4, and the timer individual management unit. 104 measures which observer is using which glasses and how long a 3D image is viewed continuously. Even when the observer changes the glasses in the middle and views the 3D image with other glasses, the timer individual management unit 104 knows who the observer is based on the detection result of the observer detection unit 101. The timer that measures the time during which the stereoscopic image is continuously viewed continues to be measured without being reset while viewing the 3D image, regardless of which glasses the viewer uses to enjoy the 3D image.

  The timer individual management unit 104 extracts individual data of the observer from the observer and stereoscopic glasses database 102 when the observer starts viewing the 3D image, and sets the stereoscopic image continuous viewing limit time and the continuous break time from the extracted data. Search and store the value as reference data. The timer individual management unit 104 determines whether or not the value of the timer for measuring the viewer's stereoscopic image continuous viewing time exceeds the reference data of the stereoscopic image continuous viewing time limit since the viewer starts viewing the 3D image. Compare and confirm. When it exceeds, the control unit 103 is notified that the stereoscopic image continuous viewing time limit has been exceeded. The control unit 103 issues a warning to the observer.

  There are several possible warning methods. For example, the image data of the observer is displayed on the display unit 109, or the image data of the stereoscopic glasses currently used by the observer to be warned is displayed. Alternatively, an icon for each observer or each stereoscopic eyeglass is registered. The registered observer or stereoscopic glasses icon is displayed on a portion of the screen when each observer is viewing a 3D image, and the stereoscopic glasses are similarly used to view the 3D image. Is displayed on a part of the screen. Image data of an observer displayed on a part of the screen, image data of stereoscopic glasses currently used by an observer to be warned, or an icon of each observer displayed on a part of the screen Or you may make it notify that the icon of each glasses for stereoscopic visions blinks, or the color scheme changes to red and the stereoscopic image continuous viewing time limit is exceeded. Alternatively, information on an observer who has exceeded the stereoscopic image continuous viewing time, such as a name, may be displayed on the display screen by the OSD to notify that the stereoscopic image continuous viewing time limit has been exceeded. Furthermore, a method of warning by voice, warning sound, lighting of LED, etc. can be considered. Here, the individual timer management unit 104 has been described to notify the control unit 103 that the stereoscopic image continuous viewing limit time has been exceeded, but notifies the predetermined time before the stereoscopic image continuous viewing limit time. You may do it. In this case, the display is different from the case where the stereoscopic image continuous viewing time limit is exceeded. For example, the observer icons may be switched by preparing different objects. Alternatively, the color scheme may be changed from yellow to yellow instead of red to notify the predetermined time before the stereoscopic image continuous viewing time limit.

  Furthermore, a method of providing a notification unit 207 in the stereoscopic glasses 200 and directly informing the observer that the stereoscopic image continuous viewing time limit has been exceeded may be considered. An example will be described below.

  The control unit 103 receives notification from the timer individual management unit 104 of the observer to be warned and the stereoscopic glasses used by the observer at a predetermined time before the stereoscopic image continuous viewing time limit. The control unit 103 notifies the stereoscopic eyeglasses 200 used by the warning target observer that the stereoscopic image continuous viewing time limit will be exceeded after a predetermined time by superimposing the synchronization signal on the synchronization signal. A control signal is transmitted. With this signal, the stereoscopic glasses 200 may be switched to the 2D mode, or after transmitting a control signal notifying that the stereoscopic image continuous viewing limit time is exceeded after a predetermined time, the stereoscopic image continuous viewing limit time is set. A control signal for instructing switching to the 2D mode may be transmitted together with the excess.

The receiving unit 201 of the stereoscopic glasses 200 receives and separates the synchronization signal transmitted in synchronization with the display timing of the right-eye image and the left-eye image, and the control signal transmitted superimposed on the synchronization signal. . The received control signal is transferred to the control unit 203 and analyzed. If it is determined that the control signal is a signal notifying that the stereoscopic image continuous viewing limit time has been exceeded, the control unit 203 uses the notification unit 207 to limit the stereoscopic image continuous viewing limit to an observer who uses the stereoscopic glasses 200. Notify when the time is exceeded. The notification unit 207 may notify the observer by sound, warning sound, LED lighting, etc., or may be constituted by a small motor and vibrate. Furthermore, the opening / closing cycle of the right-eye shutter 204 and the left-eye shutter 205 may be notified in a special pattern.
Furthermore, the control unit 203 automatically switches from the 3D mode to the 2D mode to the synchronization circuit 202 after the elapse of a predetermined time after receiving a signal notifying that the stereoscopic image continuous viewing time limit has been exceeded. Further, after receiving a control signal for switching to the 2D mode transmitted from the control unit 103 of the stereoscopic image display apparatus 100 via the transmission unit 105 when the stereoscopic image continuous viewing time limit is exceeded, the stereoscopic glasses 200 are received. The control unit 203 may instruct the synchronization circuit 202 to switch from the 3D mode to the 2D mode and operate in the 2D mode.

  In addition to the first timer for each observer for measuring the time during which a plurality of observers are continuously viewing 3D images, the timer individual management unit 104 allows a plurality of observers to view 3D images. Two types of timers are managed: a second timer for each observer for measuring a continuous break time.

The first timer is a timer that prevents each observer from watching the 3D image for a long time and causing eye strain, and includes image information from the image processing unit 108 and an observer detection unit. From the detection result of 101, when the control unit 103 determines that the detected observer is viewing a 3D image, the control unit 103 instructs the timer individual management unit 104 to start measuring the first timer. .
The first timer notifies the target observer that the stereoscopic image continuous viewing time limit has been exceeded, or switches the viewing mode of the stereoscopic glasses used by the target observer from the 3D mode to the 2D mode. It is also a timer used for judgment for transmitting a control signal for the purpose.

  A second timer for each observer for measuring a continuous break time during which a plurality of observers are not viewing a 3D image is displayed by the observer detected by the observer detection unit 101 of the stereoscopic image display device 100. This is a timer that is started when the 3D image is not viewed from the viewing mode. For example, if you are watching a 3D image, but you have a task and you have removed your seat, or if you were watching a 3D image, but started to view a 2D image in the middle, you are removing stereoscopic glasses. This is the case. Further, the second timer is a 2D mode for viewing a 2D image with respect to the stereoscopic glasses 200 used by an observer whose continuous viewing time measured by the first timer exceeds the stereoscopic image continuous viewing time limit. It is also a timer that is started immediately after the control unit 103 transmits a control signal for instructing switching to.

Furthermore, even when the power of the stereoscopic image display apparatus of the present invention is turned off, the observer is not viewing the 3D image, and is included in the measurement target of the second timer. Accordingly, not only the case where the second timer is already activated, but also the case where the power is suddenly turned off when viewing the 3D image is included. When the apparatus is turned off, the second timer operates using a backup power supply, and continues to measure until a predetermined continuous break time elapses after viewing the 3D image. However, if the power is turned off while viewing the 2D image, after viewing the 3D image, the second timer for all viewers has already stopped for a predetermined continuous break time. This is not the case. This function resets the second timer by intentionally turning off the power of the apparatus so that the observer does not continue to view 3D images again before the continuous break time elapses. Is to do. A switch for turning this function on and off may be placed in the initial setting item of the apparatus and managed using a password or the like.
Further, after a predetermined continuous break time elapses, it is used for determination for transmitting a control signal for switching the viewing mode of the stereoscopic glasses used by the target observer from the 2D mode to the 3D mode. It is also a timer.

  When the predetermined continuous break time measured by the second timer elapses, the timer individual management unit 104 notifies the control unit 103 that the second timer of the target observer has passed the predetermined continuous break time. The control unit 103 stops the second timer. Then, the control unit 103 resets the first timer operated by the same observer, that is, sets the time 0, and then stops the first timer. The first timer is not released when the user does not pass a predetermined continuous break time. Further, the control unit 103 views the 2D image set for the stereoscopic glasses 200 used by the observer whose continuous viewing time measured by the first timer exceeds the stereoscopic image continuous viewing time limit. Then, the control signal for switching the viewing mode of the stereoscopic glasses to the 3D mode for viewing the 3D image is transmitted again so that the observer can view the 3D image again.

  These stereoscopic image continuous viewing time limit and continuous break time may be registered in the individual data of the observer and the observer in the stereoscopic eyeglass database 102, or the same time may be set for all observers. Anyway. Moreover, you may make it provide stereoscopic image continuous viewing time limit and continuous rest time according to an observer's age. For example, for a child under 15 years old, the stereoscopic image continuous viewing time limit is 1 hour and the continuous break time is 10 minutes. If the child is over 15 years old, the stereoscopic image continuous viewing time limit is 2 hours and the continuous break time is 15 minutes or more. And so on. In this embodiment, the stereoscopic image continuous viewing limit time and the continuous break time are described as examples registered in the individual data of the observer and the stereoscopic glasses database 102.

  FIG. 3 is a diagram for explaining the individual selection mark portion MK of the stereoscopic glasses 200 according to the embodiment of the present invention. FIG. 3A shows an example in which marks having different shapes for sorting as shown in the center part of the glasses are pasted as individual sorting mark parts MK. FIG. 3B shows an example in which different numbers of marks for selection are pasted on the peripheral portions of the glasses as the individual selection marks MK. Further, in FIG. 3C, as individual selection mark portions MK, different numbers of triangular marks are pasted on the side surfaces of the frame so that the frame portion of the glasses can be identified by the shape of the frame when viewed from the front. Examples have been described. Also, in FIG. 3D, as individual selection mark portions MK, square marks are pasted at different positions on the side of the frame so that the frame portion of the glasses can be identified by the shape of the frame when viewed from the front. Examples have been described.

  As a result of comparison with the registered stereoscopic eyeglasses 200, the observer detection unit 101 stores the stereoscopic eyeglass registration number of the stereoscopic eyeglasses 200 in the work memory if there is a collation.

  Next, the verification image data of the observer is taken out in the order of the observer registration number and sent to the observer detection unit 101. The observer detection unit 101 compares the observer verification image data from the control unit 103 with the observer image data captured by the camera of the observer detection unit 101, and identifies which observer of the observer registration number. .

  When there are a plurality of observers, the above-described stereoscopic eyeglass 200 specification and observer specific operation are repeated, and a combination of the observer registration number of the observer and the stereoscopic eyeglass registration number of the stereoscopic eyeglasses 200 is combined. Are stored in the working memory. When all the observers are identified, the observer detection unit 101 uses a combination of the observer registration number of the observer stored in the work memory and the stereoscopic glasses registration number of the stereoscopic glasses 200. The information is transferred to the control unit 103. Based on the information of the combination of the observer registration number of the observer transferred from the observer detection unit 101 and the stereoscopic eyeglass registration number of the stereoscopic eyeglasses 200, the control unit 103 uses the observer and stereoscopic eyeglass database. The individual data relating to mode selection corresponding to the observer registration number of the observer identified from 102 is called, and it is determined whether the mode selection is set to the 3D mode or the 2D mode, and the transmission unit From 105, a control signal is transmitted to the corresponding stereoscopic glasses 200. The control signal is transmitted superimposed on the synchronization signal.

  Note that when an observer or an observer who is not registered in the stereoscopic glasses database 102 or the stereoscopic glasses 200 is detected, the observer and the stereoscopic glasses photographed by the camera of the observer detection unit 101 on the display unit 109 are detected. 200 image data may be displayed, and a message such as “Not registered, please register now” or the like may be written together with the image data of the observer and the stereoscopic glasses 200 to prompt registration. Notification to an unregistered person may be performed by displaying an icon or the like on a part of the display unit 109.

FIG. 4 is a diagram for explaining the transmission timing of the synchronization signal and the control signal in the stereoscopic image display apparatus 100 according to the embodiment of the present invention.
FIG. 4A shows the display timing of a stereoscopic image signal that is a display image signal of a 3D image displayed on the display unit 109. The stereoscopic image signal is composed of a right-eye image signal and a left-eye image signal, and the right-eye image signal and the left-eye image signal are alternately displayed on the display unit 109. FIG. 4B shows a synchronization signal synchronized with the display image signal, which is H when the right image signal is displayed on the display unit 109 and L when the left eye image signal is displayed. The control signal is transmitted superimposed on this synchronization signal. In the example displayed here, a control signal transmission section is provided in a section of one cycle in which the right eye image and the left eye image are displayed. The length of this section may be sent in sections of a plurality of cycles regardless of one cycle. FIG. 4C shows a synchronization signal for controlling opening and closing of the shutter transmitted from the synchronization circuit 202 to the right-eye shutter 204. At H, the shutter is opened, and the right eye image can be seen by the observer's right eye. At L, the shutter is closed, and the left eye image cannot be seen with the observer's right eye. FIG. 4D shows a synchronization signal for controlling opening / closing of the shutter transmitted from the synchronization circuit 202 to the left-eye shutter 205. At H, the shutter is opened, and the left eye image can be seen with the left eye of the observer. At L, the shutter is closed, and the right eye image cannot be seen with the left eye of the observer.

In addition, the synchronization circuit 202 of the stereoscopic glasses 200 is switched between a mode for viewing a 3D image and a mode for viewing a 2D image by a control signal from the control unit 203.
If the mode for viewing the 3D image is set, the synchronization circuit 202 of the stereoscopic glasses 200 synchronizes with the synchronization signal received by the receiving unit 201 and the right eye shutter 204 for viewing the right eye image and the left eye. The opening / closing timing of the left-eye shutter 205 for viewing the image for use is controlled. While the synchronization signal is being received, the right-eye shutter 204 and the left-eye shutter 205 are opened and closed according to the received synchronization signal, and during the control signal transmission section in which the control signal is included in the synchronization signal, Since the synchronization signal cannot be obtained, the synchronization signal received before the control signal transmission section is maintained and the synchronization signal is free-running.

  FIG. 5 is a view for explaining the attachment / detachment detection unit 206 when the stereoscopic glasses 200 according to the embodiment of the present invention are attached and detached. An example in which the attachment / detachment detection unit 206 is attached to each of the three parts of the stereoscopic glasses 200 is shown. FIG. 5A shows a case where the attachment / detachment detection unit 206 is in the nose pad portion. In this case, it is detected whether or not current flows through the small push switch or the left and right nose pad portions, and it is determined whether the observer wears or removes the stereoscopic glasses 200. FIG. 5B shows a case where the attachment / detachment detection unit 206 is in a portion (inside the vine) that touches the skin of the head of the frame of the stereoscopic glasses 200, and detects the capacitance of the skin of the head and observes it. It is determined whether the person wears or removes the stereoscopic glasses 200. FIG. 5C shows a case where the attachment / detachment detection unit 206 is in a portion where the ear of the frame of the stereoscopic glasses 200 hits (the lower side of the vine), that is, a portion where the frame rides on the ear. A switch or a sensor that detects electrostatic capacity and detects attachment / detachment is provided to determine whether the observer wears or removes the stereoscopic glasses 200.

  By configuring the attachment / detachment detection unit 206 as shown in FIGS. 5A to 5C, when the observer wears the stereoscopic glasses 200, it is detected that the attachment / detachment detection unit 206 is attached, Power is supplied to each circuit of the eyeglasses 200 for viewing. The stereoscopic glasses 200 are initialized and started up in a 3D mode in which a 3D image can be viewed. Further, when the separation is detected, the power supply to each circuit of the stereoscopic glasses 200 is stopped.

  When displaying a 3D image on the stereoscopic image display apparatus 100 of the present invention, the viewers H1 to H4 wear the glasses 1 to 4 configured by the stereoscopic glasses 200 of the present invention, respectively. The 3D image can be viewed as it is as a 3D image according to the individual data. Further, the observer H4 can wear the glasses 4 according to the individual data and view the 3D image as a 2D image.

  In this way, according to the request of the observer who observes the 3D image, the 3D mode / 2D mode switching instruction is automatically transmitted from the stereoscopic image display apparatus 100 to the stereoscopic glasses 200, so that the 3D image is displayed. A person who cannot see or does not want to see can see a 2D image only by himself / herself even if other observers are viewing the 3D image. A person who cannot see or want to see a 3D image does not need to select 2D display every time the 3D image is displayed after wearing the glasses 200 for stereoscopic viewing. You can see the image. In addition, when all the viewers who are trying to view a 3D image on the stereoscopic image display apparatus 100 of the present invention are not wearing the stereoscopic glasses 200, all the people wearing the stereoscopic glasses 200 are 2D. If the observer desires an image, the stereoscopic image display apparatus 100 outputs either the right eye image or the left eye image of the 3D image to the display unit. 2D images can be observed comfortably without wearing 200, which is very convenient.

  Furthermore, in the stereoscopic image display device 100 of the present invention, the time during which a 3D image is continuously viewed for each observer is measured, and the stereoscopic image continuous viewing limit time set in the personal data for each observer is exceeded. Since a warning is issued before a predetermined time, a break time can be taken each time, and a 3D image can be viewed comfortably so that eyes are not tired from watching for a long time.

  Furthermore, since the viewing time is measured for each observer, it is safe because 3D images cannot be viewed continuously beyond the stereoscopic image continuous viewing time limit even if the stereoscopic glasses are changed.

  Furthermore, you can measure the time when you are not viewing the 3D image, take a continuous break time without viewing the 3D image, and after the continuous break time has elapsed, you can reset the timer that automatically limits the continuous viewing time of the stereoscopic image Convenient.

  In addition, since the stereoscopic image continuous viewing time and the continuous break time can be managed for each observer, the stereoscopic image continuous viewing time is set to 1 when the 3D image is viewed using the stereoscopic image display device, for example, when the observer is a child. Limits such as time and continuous break time of 10 minutes can be set and children can be forced to rest, so it is safe to watch with only children.

  As mentioned above, an Example is an illustration in all the points, Comprising: It is not necessarily limited to these. For example, in the present embodiment, a stereoscopic image display device and stereoscopic glasses are illustrated, but a 3D image signal and a synchronization signal are output, the synchronization signal is received, and a viewer can use a pair of glasses that can be stereoscopically viewed. It is sufficient that a stereoscopic image can be provided, and the present invention is not limited to a stereoscopic image display device and stereoscopic glasses. In addition to a stereoscopic image display device and stereoscopic glasses, the present invention provides a 3D television, 3D projector, digital video recorder, portable movie player, cellular phone, car navigation system, portable or stationary BD / DVD player, PC The present invention can be widely applied to devices that can output or display 3D image signals.

  Since the stereoscopic image display apparatus and stereoscopic glasses according to the present invention can measure and manage the viewing time for each observer, the 3D image or the 2D image can be automatically switched according to the viewing time of each observer. It is about doing.
