Description

  The present invention relates to a stereoscopic video display apparatus and a stereoscopic video display method capable of displaying left and right video data that can perceive a stereoscopic video by binocular parallax.

  In recent years, stereoscopic video technology has attracted attention because it displays two left and right images with binocular parallax on the display surface of the display, and makes the user (observer) perceive that the object exists three-dimensionally. Yes. Various proposals have been made for techniques for realizing such a three-dimensional video display. For example, an electronic shutter system (active type) and a polarization filter system (passive type) such as μpol and Xpol (registered trademark). ) Has been proposed.

  When the former electronic shutter method is adopted, the stereoscopic video display device alternately displays the left-eye video data (left-eye video data) and the right-eye video data (right-eye video data). To do. The user then displays the left-eye video through the electronic shutter glasses that open and close the left and right electronic shutters in synchronization with the switching display of the left-eye video data and the right-eye video data (hereinafter simply referred to as the left-right video data). By viewing the right-eye image with the left eye and time-sharing alternately with the right eye, it is possible to perceive a stereoscopic image based on binocular parallax.

  In the electronic shutter system, if the switching display of the left and right video data and the opening and closing of the electronic shutter glasses are not synchronized, the right eye video is mixed when viewed with the left eye, and the left eye video is mixed when viewed with the right eye. So-called crosstalk occurs. In addition, even if the switching display of the left and right video data and the opening and closing of the electronic shutter are synchronized, the response speed of the display device (display) that displays the left and right video data is slow or the response speed of opening and closing the electronic shutter glasses is slow. Similarly, crosstalk can occur. Therefore, if the opening time of the electronic shutter glasses is shortened for the left shutter and the right shutter, respectively, crosstalk can be reduced. However, if the opening time is too short, there is a problem that the luminance decreases.

  Therefore, a technique for superimposing a discrimination mark on each of the left-eye video data and the right-eye video data and displaying it on the display, and adjusting the opening / closing timing of the electronic shutter glasses according to the detection result of the discrimination mark by the discrimination mark detection device Is disclosed (for example, Patent Document 1).

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

(First embodiment: stereoscopic image display system 100)
FIG. 1 is an explanatory diagram illustrating a schematic relationship between devices included in the stereoscopic video display system 100 according to the first embodiment. As shown in FIG. 1, the stereoscopic video display system 100 includes a stereoscopic video display device 110 and electronic shutter glasses 120. The stereoscopic video display device 110 is, for example, from the broadcast station 112 through broadcast radio waves, from the server device 116 through the communication network 114 such as the Internet, a LAN (Local Area Network), a dedicated line, or from a DVD (Digital Versatile Disk), The left-eye video data and the right-eye video data having horizontal parallax are obtained from a storage medium 118 such as a BD (Blu-ray Disc) or USB (Universal Serial Bus) memory, and displayed on a display mounted on the apparatus itself. To do.

  The electronic shutter glasses 120 are provided with a left electronic shutter (for example, a liquid crystal shutter) corresponding to the left eye of the user and a right electronic shutter corresponding to the right eye, and left-eye video data and right-eye video data (left and right). When the left-eye video data is displayed in synchronization with the switching timing of the video data), the left electronic shutter (hereinafter simply referred to as the left shutter) is opened, and the right electronic shutter (hereinafter simply referred to as the right shutter). ) Is closed and when the right-eye video data is being displayed, the left shutter is closed and the right shutter is opened. By wearing the electronic shutter glasses 120, the user visually recognizes only the left-eye video data displayed on the stereoscopic video display device 110 with the left eye and only the right-eye video data with the right eye, thereby allowing binocular parallax. 3D images can be perceived.

  The stereoscopic image display apparatus 110 according to the present embodiment has a frame frequency (frame rate) of 60 Hz when the left-eye video data and the right-eye video data are acquired in parallel in two systems. It has a double speed processing function that alternately displays the same left-eye video data and the same right-eye video data twice on the display at a frequency of 4 times (240 Hz).

  FIG. 2 is an explanatory diagram for explaining the display processing using the double speed processing function and the opening / closing timing of the electronic shutter glasses 120. The stereoscopic video display device 110 acquires the left and right video data, which is a video signal composed of the left-eye video data and the right-eye video data, in parallel with two systems at a frame frequency of 60 Hz, for example. Here, in the frame sequential method, left-eye video data having information of all pixels for displaying one screen and right-eye video data having information of all pixels for displaying one screen are respectively referred to as frame data. In other words, the stereoscopic image display apparatus 110 displays frame data on the display in a frame period according to the frame frequency.

  Here, when the double-speed processing function is not used in the stereoscopic video display device 110, the left-eye video data and the right-eye video data are alternately displayed at twice the acquired frame frequency (120 Hz). .

  When the above double speed processing function is used for the stereoscopic image display device 110, the display (for example, 1080 scanning lines) is displayed on the same left-eye image data (cross-hatched in FIG. 2) as shown in FIG. 2) and the same right-eye video data (shown in white in FIG. 2) are repeatedly displayed twice each, so that during the frame period when the video data is acquired in parallel in two systems (one frame) Period), the same left-eye video data (FRD1, 2 in FIG. 2) is continuously displayed twice, and the same right-eye video data (FRD3, 4 in FIG. 2) is continuously displayed twice. It will be. Therefore, the frame frequency for displaying on the display when using the double speed processing function is four times the frame frequency when the video data is acquired in parallel in two systems (in the case of acquiring in parallel in two systems). 240 Hz when the frame frequency is 60 Hz).

  By using such a magnification processing function, it is possible to shorten the scanning time of the left and right video data (time from the start of scanning to the end of scanning) by the display. Therefore, compared with the case where the above double speed processing function is not used, the rewriting (switching) time of the left and right video data can be shortened, and the time during which only one-eye video data is displayed on the screen can be increased. The brightness of the left and right video data can be improved by extending the time during which the electronic shutter of the electronic shutter glasses 120 can be opened.

  Here, the scanning period X in which the video data for the right eye is shifted to the video data for the left eye, and the scanning period Y in which the video data for the left eye is shifted to the video data for the right eye are the video data for the left eye and the video for the right eye. Since data is mixed, crosstalk occurs when the electronic shutter glasses 120 are open during the scanning periods X and Y.

  Therefore, as shown in FIG. 2B, the left shutter of the electronic shutter glasses 120 is opened from the end of the display of the right-eye video data of FRD0, and is closed before the start of the display of the right-eye video data of FRD3. By adjusting so that no crosstalk occurs. In the present embodiment, the right shutter of the electronic shutter glasses 120 is adjusted in the same manner as the left shutter. However, for convenience of explanation, only the left shutter will be described, and description of the right shutter will be omitted.

  Here, if the response speed of the display is slow or the response speed of opening / closing the electronic shutter glasses 120 is slow, crosstalk may also occur. Therefore, as shown in FIG. 2C, the left shutter of the electronic shutter glasses 120 is opened at the time when the display response time P is added from the display end time of the right-eye video data of FRD0, and the right eye of the FRD3 is displayed. 3D video can be perceived by the user without causing crosstalk by adjusting to close at the time when the response time Q of the electronic shutter glasses 120 is taken into consideration (advanced) in consideration of the response time Q of the electronic shutter glasses 120 Can be made. However, when the response speed of the display or the electronic shutter glasses 120 changes due to a change in room temperature or time, or when other electronic shutter glasses other than the adjusted electronic shutter glasses 120 are used, crosstalk still occurs. .

  Therefore, the present embodiment describes a stereoscopic image display apparatus 110 that can easily check whether or not crosstalk has occurred and can adjust the opening and closing timing of the electronic shutter when crosstalk has occurred. To do. Hereinafter, each functional unit constituting the stereoscopic video display device 110 will be described, and then a stereoscopic video display method using the stereoscopic video display 110 will be described in detail.

(3D image display device 110)
FIG. 3 is a functional block diagram illustrating schematic functions of the stereoscopic video display apparatus 110 according to the first embodiment. As shown in FIG. 3, the stereoscopic video display device 110 includes a video acquisition unit 150, a video processing unit 152, a frame memory 154, an address control unit 156, a guide data generation unit 158, and a guide data acquisition unit 160. The image processing unit 162, the display control unit 164, the display 166, the shutter signal generation unit 168, the operation unit 170, the shutter signal adjustment unit 172, and the signal transmission unit 174 are configured.

  The video acquisition unit 150 acquires left-eye video data and right-eye video data (left-right video data) having binocular parallax for perceiving stereoscopic video, for example, at a frame frequency of 60 Hz. The video acquisition unit 150 may acquire the left-eye video data and the right-eye video data individually in two systems from different paths (lines), or from one path (in one system) with a frame frequency of 120 Hz. You may acquire as integral data. Hereinafter, a case where the frame frequency when the video acquisition unit 150 acquires the left and right video data in two systems in parallel is 60 Hz will be described.

  The video processing unit 152 performs video signal processing such as R (Red), G (Green), and B (Blue) processing and enhancement processing on the left and right video data output from the video acquisition unit 150, and writes the result to the frame memory 154.

  The frame memory 154 is configured by a storage medium such as a RAM, and temporarily stores left and right video data, which has been subjected to video signal processing by the video processing unit 152, in units of frames.

  The address control unit 156 generates a vertical synchronization signal having a frequency four times the frame frequency of the left and right video data acquired by the video acquisition unit 150, and each of the video data read from the frame memory 154 based on the vertical synchronization signal. A first toggle signal indicating whether the frame data is left-eye video data or right-eye video data, and a read address for the video processing unit 162 to read the left-right video data from the frame memory 154 are generated. The address control unit 156 causes the video processing unit 162 to alternately read the left-eye video data and the right-eye video data from the frame memory 154 using the read address generated by itself.

  FIG. 4 is an explanatory diagram for explaining the processing of the address control unit 156. Here, as shown in the memory map of FIG. 4A, the head of the left-eye video data address of the left-right video data held in the frame memory 154 is 0, and the right-eye video data address is An example in which the left-eye video data is offset by OFST will be described.

  As shown in FIG. 4B, the video processing unit 152 converts the left and right video data into the frame memory 154 at a frame frequency (60 Hz in this case) when the video acquisition unit 150 acquires the left and right video data in parallel in two systems. Write to. Then, the address control unit 156 determines the FRD1 based on the vertical synchronization signal (see FIG. 4D) having a frequency four times the frame frequency when the left and right video data is written (when the left and right video data is acquired). A first toggle signal (see FIG. 4E) is generated, in which “0” is indicated by 2 and “1” is indicated by FRD 3 and 4, and a low level signal and a high level signal are alternately repeated. Further, as shown in FIG. 4F, the address control unit 156 sets the read address offset by OFST when the first toggle signal indicates 0 and when the first toggle signal indicates 1 Generate.

  Then, as shown in FIG. 4C, while the video processing unit 152 is writing the frame B, the address control unit 156 uses the read address (see FIG. 4F) to parallel the left and right video in two systems. The left eye video data (indicated by AL in FIG. 4) of the frame A held in the frame memory 154 in the video processing unit 162 at a frequency (240 Hz) that is four times the frame frequency at the time of data acquisition. Then, the right-eye video data for frame A (indicated by AR in FIG. 4) is read twice.

  The address control unit 156 outputs the first toggle signal to the video processing unit 162, the vertical synchronization signal and the horizontal synchronization signal to the display control unit 164, and the vertical synchronization signal and the first toggle signal to the shutter signal generation unit 168.

  The guide data generation unit 158 generates first guide data, second guide data, and index data. The first guide data, the second guide data, and the index data will be described in detail later.

  The guide data acquisition unit 160 acquires the first guide data, the second guide data, and the index data generated by the guide data generation unit 158. In this embodiment, the guide data acquisition unit 160 acquires the first guide data, the second guide data, and the index data generated by the guide data generation unit 158. However, the first guide data, the second guide data, and the index data are acquired. One or a plurality of data selected from the group can be stored in advance in a memory (not shown) and acquired from the memory.

  When the confirmation mode for confirming whether or not crosstalk has occurred is selected in response to an operation input to the operation unit 170 or the like by the user, the video processing unit 162 selects the first toggle output from the address control unit 156. Based on the signal, the first guide data acquired by the guide data acquisition unit 160 is superimposed on only one of the left-eye video data and the right-eye video data. Further, the video processing unit 162 superimposes the second guide data acquired by the guide data acquisition unit 160 on video data on which the first guide data is not superimposed on the left-eye video data and the right-eye video data. . Furthermore, the video processing unit 162 superimposes the index data acquired by the guide data acquisition unit 160 on either the left-eye video data or the right-eye video data.

  In the present embodiment, the presence or absence of crosstalk is confirmed for each eye by enabling only the electronic shutter on one eye side of the electronic shutter glasses 120 or closing the electronic shutter on the other eye side. Therefore, the video processing unit 162 specifically superimposes the second guide data on the video data for the eye for checking whether or not crosstalk has occurred, and checks whether or not crosstalk has occurred. The first guide data is superimposed on the video data for the eye that is not the eye. As described above, the first guide data and the second guide data relatively change the superimposition destination video data depending on whether the eye to be confirmed is left or right. In the following, for convenience of explanation, the left eye guide data is absolutely superimposed on the left eye video data, and the right eye guide data is absolutely superimposed on the right eye video data. Therefore, the left eye guide data corresponds to the first guide data or the second guide data depending on whether the eye to be confirmed is left or right.

  Here, a case where the crosstalk of the video data for the right eye with respect to the video data for the left eye is confirmed (when only the video data for the left eye is visually recognized) will be described. As described above, the video processing unit 162 superimposes the left eye guide data on the left eye video data and superimposes the right eye guide data on the right eye video data. The left eye guide data functions as second guide data, and the right eye guide data functions as first guide data. Here, an example is given in which the index data is superimposed only on the left-eye video data to be checked.

  FIG. 5 is an explanatory diagram for explaining processing of the video processing unit 162. The video processing unit 162 reads the left and right video data 180 (left-eye video data 180a and right-eye video data 180b) from the frame memory 154 as shown in FIG. 5A, and as shown in FIG. 5B. The left eye guide data 182a is superimposed on the left eye video data 180a, the right eye guide data 182b is superimposed on the right eye video data 180b, and the index data 184 is superimposed on the left eye video data 180a.

  As shown in FIG. 5B, the left eye guide data 182a indicates a second on-screen display image extended in the display screen vertical direction of the display 166, and the right eye guide data 182b indicates the display screen vertical of the display 166. Fig. 3 shows a first on-screen display image extended in the direction. In the present embodiment, the first on-screen display image and the second on-screen display image are formed in a rectangular shape having substantially the same horizontal width from the uppermost line to the lowermost line of the display screen of the display 166. In addition, the index data 184 indicates an index capable of grasping the vertical position on the display 166. Here, the left eye guide data 182a and the right eye guide data 182b are on-screen display images (first on-screen display image and second on-screen display image) extended in the vertical direction of the display screen of the display 166. It is not limited to this, Arbitrary shapes may be shown.

  When the right-eye video data 180b is mixed into the left-eye video data 180a and crosstalk occurs, as shown in FIG. 5C, a part of the right-eye video data 180b is left-eye video data. It mixes in 180a.

  In general, the left-eye video data 180a and the right-eye video data 180b differ only in the horizontal position of the subject and have little difference in the video, so the left-eye video data 180a and the right-eye video data are the same. Even if only the data 180b is displayed, it is not easy to confirm whether or not crosstalk has occurred. However, the video processing unit 162 according to the present embodiment superimposes the right eye guide data 182b as the first guide data extended in the vertical direction of the display screen of the display 166 only on the right eye video data 180b, so that the right The occurrence of crosstalk can be easily confirmed based on whether or not the eye guide data 182b is visually recognized.

  In the present embodiment, the right eye guide data 182b (first guide data) is formed to be superimposed on a display position different from the left eye guide data 182a (second guide data). Accordingly, the user can distinguish and visually recognize the first on-screen display image indicated by the right eye guide data 182b and the second on-screen display image indicated by the left eye guide data 182a. The first on-screen display image and the second on-screen display image only need to have different display modes, and are not limited to different display positions, and may have different display colors.

  FIG. 6 is an explanatory diagram for explaining an example of the configuration of the image processing unit 162. For example, the guide data acquisition unit 160 acquires the left eye guide data 182a, the right eye guide data 182b, and the index data 184, sets the pixel area in which the left eye guide data 182a is arranged to “1”, and the right eye guide data 182b. A guide data control signal is generated in which the pixel area where “2” is arranged is “2”, the pixel area where the index data 184 is arranged is “3”, and the other pixel areas are “0”. As shown in FIG. 6, the switch 162a of the video processing unit 162 switches the output signal in units of pixels in accordance with the guide data control signal.

  In the present embodiment, the image processing unit 162 superimposes the first guide data on either the left-eye image data 180a or the right-eye image data 180b as a processing unit for the left and right image data 180 (replaces in units of pixels). However, the present invention is not limited to this, and other processing means may be employed.

  For example, when confirming the occurrence of crosstalk in the left-eye video data 180a, the video processing unit 162 converts the left and right video data 180 acquired by the video acquisition unit 150 into data indicating a solid color, and as data indicating a solid color. The right-eye guide data 182b (first guide data) acquired by the guide data acquisition unit 160 is superimposed on the converted right-eye video data, and the left-eye guide is converted into the left-eye video data converted as data indicating solid color. Data 182a (second guide data) and index data 184 may be superimposed. As a result, since the left and right video data as the background indicate plain, the visibility of the right eye guide data 182b (first guide data), the left eye guide data 182a (second guide data), and the index data 184 can be improved. It is possible to more easily confirm the occurrence of crosstalk.

  Further, the video processing unit 162 replaces only one of the left-eye video data 180a and the right-eye video data 180b acquired by the video acquisition unit 150 with the first guide data acquired by the guide data acquisition unit 160. You can also

  FIG. 7 is an explanatory diagram for explaining another configuration example of the video processing unit 162. When the video processing unit 162 performs the replacement, the guide data generation unit 158 is the same as the left-eye video data 180a including the left-eye guide data 182a and other regions as shown in FIG. 7A. The left-eye replacement data 186a having the same size and the right-eye replacement data 186b having the same size as the right-eye video data 180b including the right-eye guide data 182b and other regions are generated.

  The guide data acquisition unit 160 sets the frame period for replacement with the left eye replacement data 186a to “1”, the frame period for replacement with the right eye replacement data 186b, and “0” for the frame period for displaying the left and right video data 180 as they are. A guide data control signal such as Then, as shown in FIG. 7B, the switch 162b of the video processing unit 162 switches the output signal in units of frames in accordance with the guide data control signal. In this way, the occurrence of crosstalk can be easily confirmed simply by replacing the left-eye video data 180a with the left-eye replacement data 186a or by replacing the right-eye guide data 182b with the right-eye replacement data 186b. .

  The display control unit 164 includes left set data (first set data) in which one or a plurality (two times here) of left-eye video data 180a on which the left-eye guide data 182a and the index data 184 are superimposed, and the right eye Right set data (second set data) in which one or a plurality (two times in this case) of right-eye video data 180b on which the guide data 182b is superimposed are alternately displayed on the display 166 based on the vertical synchronization signal.

  The display 166 is configured by a liquid crystal display, an organic EL (Electro Luminescence) display, or the like, and instructed data (for example, left eye guide data 182a and index data 184 are superimposed) in accordance with a control command of the display control unit 164. The left-eye video data 180b and the right-eye guide data 182b superimposed on the right-eye video data 180b) are displayed.

  The shutter signal generation unit 168 generates a shutter signal for controlling the opening and closing of the left and right electronic shutters of the electronic shutter glasses 120 for each of the left shutter and the right shutter based on the vertical synchronization signal and the first toggle signal. The shutter signal is, for example, a signal that sets the open section of the electronic shutter as “1” and the closed section as “0” as shown in FIGS. 2B and 2C, and the timing of starting the open section. The (start time) and the timing (end time) for ending the open section can be adjusted in units of one line scanning time. In the initial state before adjustment, the shutter signal is in the same period as the section where the first toggle signal is “0” in the left shutter open section and the section where the first toggle signal is “1” in the right shutter open section. Generated.

  Here, the shutter signal generation unit 168 sets the opening section of the electronic shutter by determining the timing for starting the opening section and the timing for starting the closing section, but the present invention is not limited to this, and the opening section can be set. What is necessary is just to be a thing, and you may set an open section by determining the timing and open section width which start an open section.

  The operation unit 170 includes switches such as operation keys, a cross key, and a joystick, and accepts user operation inputs. When a remote controller for remote operation is provided, the remote controller also functions as the operation unit 170.

  The shutter signal adjustment unit 172 adjusts the start point (open timing) and end point (close timing) of the shutter signal generated by the shutter signal generation unit 168 in accordance with a user operation input through the operation unit 170.

  FIG. 8 is an explanatory diagram for explaining processing of the shutter signal adjustment unit 172. In FIG. 8, in order to facilitate understanding, it is assumed that the left-eye video data 180a and the right-eye video data 180b are data indicating a solid color. When a part of the right-eye video data 180b is mixed in the left-eye video data 180a to cause crosstalk, a part of the mixed right-eye video data 180b is, for example, FIG. 8A. Or as shown in FIG.

  Since the scanning of the image starts from the top of the display 166, when the crosstalk shown in FIG. 8A occurs, the opening timing of the left shutter of the electronic shutter glasses 120 is too early because of the crosstalk. If the opening timing of the left shutter is delayed, the right-eye video data 180b and the right-eye guide data 182b as the first guide data superimposed thereon are not displayed in order from the top.

  On the other hand, when the crosstalk shown in FIG. 8B occurs, the closing timing of the left shutter of the electronic shutter glasses 120 is too late because of the crosstalk, so if the closing timing of the left shutter is advanced, The right-eye video data 180b and the right-eye guide data 182b as the first guide data superimposed thereon are not displayed in order from the bottom.

  Therefore, the shutter signal adjustment unit 172 delays the opening timing of the left shutter of the electronic shutter glasses 120 or advances the closing timing so that the right eye guide data 182b (first guide data) is not displayed. Then, the start point and end point of the shutter signal generated by the shutter signal generation unit 168 are adjusted. This makes it possible for the user to perceive a stereoscopic video from which crosstalk has been eliminated.

  Here, the video processing unit 162 superimposes index data 184 indicating an index that allows the vertical position of the display 166 to be grasped on the left-eye video data 180a. By superimposing the index data 184, the user can quantitatively measure the degree of crosstalk, and if the quantitative value is transmitted to other users, uniform adjustment is possible even for other users. It becomes. Even when other electronic shutter glasses are used, the same crosstalk adjustment amount can be reproduced by storing the quantitative value.

  Further, in the present embodiment, the first on-screen display image is formed in a rectangular shape having substantially the same horizontal width from the uppermost line to the lowermost line of the display screen of the display 166, but is not limited thereto. The length of the first on-screen display image itself such as the first on-screen display image indicated by the first guide data 188 shown in FIG. 8C is formed in such a manner that it can be grasped by the number of stripes, for example. Also good. Accordingly, the user can quantitatively measure the degree of crosstalk without superimposing the index data 184, and uniform adjustment is possible if the quantitative value is stored or transmitted to other users. .

  Incidentally, the image processing unit 162 superimposes the second guide data (left eye guide data 182a in FIG. 8) on the left eye image data 180a. In order to reduce the crosstalk, the opening timing of the electronic shutter glasses 120 may be delayed or the closing timing may be advanced so that the right eye guide data 182b (first guide data) disappears. However, if only the right eye guide data 182b (first guide data) is viewed and the opening / closing timing of the electronic shutter glasses 120 is adjusted, the opening timing is delayed too much or the closing timing is set too early, but the crosstalk disappears. There is a possibility that the luminance of the left and right video data 180 may decrease.

  Therefore, the video processing unit 162 superimposes the second guide data on the video data for the eye to be adjusted. Then, if the opening timing of the electronic shutter glasses 120 is delayed too much or the closing timing is advanced too early, even the second guide data is lost. Accordingly, the shutter signal adjustment unit 172 adjusts the opening / closing timing of the electronic shutter glasses 120 so that the first guide data disappears and the second guide data remains, so that the luminance of the left and right video data 180 due to excessive adjustment is unnecessary. It is possible to avoid a situation where the speed falls.

  The signal transmission unit 174 transmits the shutter signal adjusted by the shutter signal adjustment unit 172 through wireless communication such as infrared rays, Bluetooth (registered trademark), IEEE802.11a / b / g / n, or wired communication, to the electronic shutter glasses 120 itself or electronic It transmits to the control apparatus which controls shutter glasses 120.

  Since the stereoscopic video display device 110 according to the present embodiment can adjust the opening / closing timing of the electronic shutter glasses 120 via the operation unit 170, any electronic shutter glasses can be used for the stereoscopic video display device 110. Can be adjusted.

  Further, in the present embodiment, the configuration in which the video processing unit 152 is in the front stage of the frame memory 154 has been described. However, the left-eye video data and the right-eye video are included in the format of the left and right video data acquired by the video acquisition unit 150. For the left eye within one video data, such as a line sequential format that displays data in a row, and a checkerboard format that displays left-eye video data and right-eye video data alternately up and down and left and right like a checkered pattern. In some cases, the video data area and the right-eye video data area are mixed, and if the video processing unit 152 is in the preceding stage of the frame memory 154, video signal processing such as enhancement processing that refers to peripheral pixels is performed. It may not be possible.

  In such a case, the video signal processing needs to be performed after the processing for separating the left-eye video data and the right-eye video data through the frame memory 154, and as shown in FIG. The three switches 190 a, 190 b, and 190 c that are interlocked are provided, and input signals of the video processing unit 152, the frame memory 154, and the video processing unit 162 are switched according to the format acquired by the video acquisition unit 150. For example, when the format acquired by the video acquisition unit 150 is a line sequential format or a checkerboard format, the switches 190a, 190b, and 190c are switched as indicated by broken lines in FIG.

  In addition, the signal transmission unit 174 transmits the shutter signal adjusted by the shutter signal adjustment unit 172 for the open interval, but the function of adjusting the open interval to the electronic shutter glasses 120 itself or the control device for the electronic shutter glasses 120. , The signal transmission unit 174 may transmit the frame synchronization signal itself such as the first toggle signal. In this case, the electronic shutter glasses 120 generate a shutter signal based on the frame synchronization signal.

  Furthermore, in the above-described example, the case where the crosstalk of the left-eye video data 180a is confirmed has been described. Therefore, the right-eye guide data 182b functions as the first guide data, and the left-eye guide data 182a serves as the second guide data. However, when the crosstalk of the right-eye video data 180b is confirmed, the left-eye guide data 182a functions as the first guide data, and the right-eye guide data 182b functions as the second guide data.

  As described above, according to the stereoscopic image display apparatus 110 according to the present embodiment, it is possible to easily confirm whether or not crosstalk has occurred. In addition, since the opening / closing timing of the electronic shutter glasses 120 can be adjusted via the operation unit 170, any electronic shutter glasses can be adjusted as long as the shutter signal can be recognized. Therefore, not only the electronic shutter glasses 120 previously sold in combination with the stereoscopic image display device 110, but also other compatible electronic shutter glasses can adjust the opening / closing timing, and any electronic shutter glasses can be adjusted. Even if it is 120, there is no crosstalk, and it is possible to make the user perceive a high-luminance stereoscopic image.

(3D image display method)
In addition, a stereoscopic video display method using the above-described stereoscopic video display device 110 is also provided. FIG. 10 is a flowchart for explaining specific processing of the stereoscopic video display method according to the first embodiment.

  When the video acquisition unit 150 acquires the left-eye video data 180a and the right-eye video data 180b having horizontal parallax (S200), the guide data acquisition unit 160 acquires the first guide data, the second guide data, and the index data 184. Obtain (S202).

  Then, the video processing unit 162 converts the left guide data 182a as the first guide data and the second guide data acquired in the guide data acquisition step S202 and the index data 184 into the left eye video data 180a and the first guide data. The data and the right eye guide data 182b as the second guide data and the index data 184 are superimposed on the right eye video data (S204).

  Then, the display control unit 164 causes the display 166 to alternately display the left-eye video data and the right-eye video data generated in the data superimposing step S204 (S206).

  Here, when the opening / closing timing of the left shutter of the electronic shutter glasses 120 is adjusted (YES in S208), the right shutter is kept closed during the adjustment period (S210). Then, the shutter signal adjustment unit 172 expands / contracts the opening / closing timing of the shutter signal for the left shutter according to the operation input by the user via the operation unit 170 (S212), and the shutter signal for the left shutter is displayed on the display 166. The displayed right eye guide data 182b disappears and the left eye guide data 182a remains.

  On the other hand, when the opening / closing timing of the right shutter of the electronic shutter glasses 120 is adjusted (NO in S208), the left shutter is kept closed during the adjustment period (S214). Then, the shutter signal adjustment unit 172 expands and contracts the opening / closing timing of the shutter signal for the right shutter according to the operation input by the user via the operation unit 170 (S216), and the shutter signal for the right shutter is displayed on the display 166. The displayed left eye guide data 182a disappears and the right eye guide data 182b remains.

  The signal transmission unit 174 transmits the shutter signal for the left shutter and the shutter signal for the right shutter adjusted in the adjustment steps S212 and 216 to the electronic shutter glasses 120 (S218).

  As described above, also in the stereoscopic image display method according to the present embodiment, it is possible to easily confirm whether or not crosstalk has occurred.

(Second embodiment: stereoscopic image display device 310)
In the first embodiment described above, the same left-eye video data 180a is consecutively performed twice, and the same right-eye video data 180b is consecutively performed twice, left-left, right-right, left-left, right Since the left and right video data are displayed in the order of right,..., When confirming crosstalk in the left eye video data 180a, the first guide data is displayed in both the frame periods in which the same right eye video data 180b continues. However, in the second embodiment, different guide data is superimposed on each frame period in the frame period in which the same right-eye video data 180b is continuous. A stereoscopic image display device 310 that can easily adjust the shutter glasses 120 will be described.

  FIG. 11 is a functional block diagram showing schematic functions of the stereoscopic video display apparatus 310 according to the second embodiment. As shown in FIG. 11, the stereoscopic video display device 310 includes a video acquisition unit 150, a video processing unit 152, a frame memory 154, an address control unit 356, a guide data generation unit 358, and a guide data acquisition unit 360. The image processing unit 362, the display control unit 164, the display 166, the shutter signal generation unit 168, the operation unit 170, the shutter signal adjustment unit 172, and the signal transmission unit 174 are configured. The video acquisition unit 150, the video processing unit 152, the frame memory 154, the display control unit 164, the display 166, the shutter signal generation unit 168, and the operation unit 170 that have already been described as constituent elements in the first embodiment. The shutter signal adjustment unit 172 and the signal transmission unit 174 have substantially the same functions, and thus the description thereof is omitted. Here, the address control unit 356, the guide data generation unit 358, and the guide data acquisition unit having different configurations are described. The video processing unit 362 will be mainly described.

  The address control unit 356 generates a vertical synchronization signal having a frequency four times the frame frequency of the left and right video data acquired in parallel by the video acquisition unit 150 in two systems, and based on the vertical synchronization signal, the first toggle signal and Generate a read address. In the present embodiment, the address control unit 356 generates a second toggle signal based on the vertical synchronization signal.

  FIG. 12 is an explanatory diagram for explaining the processing of the address control unit 356. As shown in FIG. 12A, the video processing unit 152 writes the left and right video data in the frame memory 154 at the frame frequency (60 Hz in this case) when the video acquisition unit 150 acquires the left and right video data. Note that the reading of the left and right video data, the generation of the vertical synchronization signal, the generation of the first toggle signal, and the generation of the read address in FIGS. 12B to 12E are the same as those in FIG. Since it is substantially the same as the processing of the address control unit 156 shown in d) to (f), the description is omitted.

  In the present embodiment, the address control unit 356 is based on the vertical synchronization signal shown in FIG. 12C, as shown in FIG. 12F, in frame units of the frame frequency (240 Hz in this case) in the display control unit 164. To generate a second toggle signal. Then, the address control unit 356 outputs the first toggle signal and the second toggle signal to the video processing unit 362, the vertical synchronization signal and the horizontal synchronization signal to the display control unit 164, and the vertical synchronization signal and the first toggle signal to the shutter signal generation unit. To 168.

  The guide data generation unit 358 generates first guide data, second guide data, third guide data, and fourth guide data. The first guide data indicates a first on-screen display image extended in the vertical direction of the display screen of the display 166, and the second guide data is extended in the vertical direction of the display screen of the display 166, and the first on-screen display image and Indicates a second on-screen display image having a different display mode. The third guide data is a third on-screen display image that extends in the vertical direction of the display screen of the display 166 and has a display mode different from the first on-screen display image and the second on-screen display image. The fourth guide data is a fourth on-screen display image that is extended in the vertical direction of the display screen of the display 166 and has a display mode different from the first on-screen display image, the second on-screen display image, and the third on-screen display image. Show. In the present embodiment, the first guide data, the second guide data, the third guide data, and the fourth guide data are formed so as to be superimposed on different display positions, and are formed so as to show different display colors. .

  The guide data acquisition unit 360 acquires first guide data, second guide data, third guide data, and fourth guide data.

  The video processing unit 362 displays the first guide data as the earliest video data to be displayed on the display 166 out of the set data obtained by repeating either the left-eye video data or the right-eye video data a predetermined number of times. Of the other set data of the left-eye video data and the right-eye video data, the third guide data is superimposed on the last video data to be displayed on the left and the first guide data and the third guide data are not superimposed. The second guide data is superimposed on the earliest video data to be displayed on the display 166, and the fourth guide data is superimposed on the last video data to be displayed on the display 166.

  In the present embodiment, the presence or absence of crosstalk is confirmed for each eye by enabling only the electronic shutter on one eye side of the electronic shutter glasses 120 or closing the electronic shutter on the other eye side. Therefore, the video processing unit 362 specifically superimposes the second guide data and the fourth guide data on the video data for eyes for checking whether or not crosstalk has occurred, and whether or not crosstalk has occurred. The first guide data and the third guide data are superimposed on the video data for the eye that is not the eye to be confirmed. As described above, in the first guide data, the second guide data, the third guide data, and the fourth guide data, the superimposition destination video data relatively changes depending on whether the eye to be confirmed is left or right. In the following, for convenience of explanation, first left-eye guide data and second left-eye guide data are used for left-eye video data, and first right-eye guide data and second right-eye guide are used for right-eye video data. Absolutely superimpose data. Therefore, the first left eye guide data corresponds to the first guide data, the second guide data, or the second left eye guide data corresponds to the first left or right, depending on whether the eye to be confirmed is left or right. It corresponds to 3 guide data or 4th guide data.

  Here, as in the first embodiment described above, a case where crosstalk of video data for right eye with respect to video data for left eye is confirmed (when only video data for left eye is visually recognized) will be described. The video processing unit 362 outputs the first left eye guide data to the earliest left eye video data to be displayed on the display 166 from the left set data obtained by repeating the left eye video data a predetermined number of times (here, twice). Of the left set data, the second left eye guide data is superimposed on the last left eye video data to be displayed on the display 166, and the right eye video data is displayed on the display 166 among the right set data that is repeated a predetermined number of times. The first right eye guide data is superimposed on the earliest right eye video data to be performed, and the second right eye guide data is superimposed on the last right eye video data to be displayed on the display 166 of the right set data. The first left eye guide data functions as second guide data, the second left eye guide data functions as fourth guide data, the first right eye guide data functions as first guide data, and the second right data The eye guide data functions as third guide data.

  As shown in FIG. 12, in the present embodiment, the left and right video data read from the frame memory 154 is obtained by repeating the left-eye video data twice in one frame period when the video data is acquired in two systems in parallel. It includes left set data 370a and right set data 370b obtained by repeating the right-eye video data twice.

  FIG. 13 is an explanatory diagram for explaining processing of the video processing unit 362. As shown in FIGS. 13A and 13B, the video processing unit 362 adds first left-eye guide data 380a as second guide data to the earliest left-eye video data L1 in the left set data 370a. The second left eye guide data 380c as the fourth guide data is added to the last left eye video data L2 of the left set data 370a, and the first guide is set to the earliest right eye video data R1 of the right set data 370b. The first right eye guide data 380b as data is superimposed on the last right eye video data R2 in the right set data 370b, and the second right eye guide data 380d as third guide data is superimposed.

  The display control unit 164 includes the left-eye video data L1 on which the first left-eye guide data 380a is superimposed, the left-eye video data L2 on which the second left-eye guide data 380c is superimposed, and the first right-eye guide data 380b. The right-eye video data R1 and the right-eye video data R2 on which the second right-eye guide data 380d are superimposed are sequentially displayed on the display 166.

  Here, when the crosstalk in the left-eye video data is confirmed and the first right-eye guide data 380b is displayed as shown in FIG. 13C, the first right-eye guide data 380b is the right Since the data is superimposed on the earliest right-eye video data R1 in the set data 370b, the right-eye video data R1 is mixed in the last left-eye video data L2 in the left set data 370a. I understand that.

  Therefore, it is possible to intuitively understand that crosstalk will be eliminated if the closing timing of the left shutter of the electronic shutter glasses 120 is advanced by merely allowing the user to visually recognize the guide data displayed on the display 166.

  Similarly, as shown in FIG. 13D, when the second right eye guide data 380d is displayed, the second right eye guide data 380d is superimposed on the last right eye video data R2 in the right set data 370b. Thus, it can be seen that the right-eye video data R2 is mixed in the earliest left-eye video data L1 in the left set data 370a.

  Therefore, it is possible to intuitively understand that the crosstalk is eliminated by delaying the opening timing of the left shutter of the electronic shutter glasses 120 only by allowing the user to visually recognize the guide data displayed on the display 166.

  In the present embodiment, the guide data generation unit 358 superimposes the first left eye guide data 380a, the first right eye guide data 380b, the second left eye guide data 380c, and the second right eye guide data 380d on different display positions. The first left eye guide data 380a, the first right eye guide data 380b, the second left eye guide data 380c, and the second right eye guide data 380d are displayed differently. The colors may be formed so as to be superimposed on the same display position.

  Further, the guide data (first left eye guide data 380a and first right eye guide data 380b) to be superimposed on the earliest video data in the set data has the same display position, and the guide to be superimposed on the last video data. The display position of the data (second left eye guide data 380c and second right eye guide data 380d) is the same, and guide data (first left eye guide data 380a and second left eye guide data superimposed on the left eye video data) The display color of the guide data 380c) is the same (for example, red), and the display color of the guide data (the first right eye guide data 380b and the second right eye guide data 380d) superimposed on the right-eye video data is the same (for example, (Blue).

  In this way, when the opening / closing timing of the left shutter is adjusted, and the color of the image where the first left eye guide data 380a is arranged is visible in purple, the first right eye guide data 380b is If the color of the image where the second left eye guide data 380c is arranged is visually recognized as purple, the second right eye guide data 380d is mixed. Therefore, the user can easily confirm whether or not crosstalk has occurred by merely visually recognizing the color of the on-screen display image displayed on the display 166. It is possible to easily grasp whether the timing for opening the shutter should be delayed or the timing for closing the electronic shutter should be advanced.

  As described above, according to the stereoscopic image display apparatus 310 according to the present embodiment, the opening timing of the electronic shutter glasses 120 may be adjusted only by looking at the display 166 when crosstalk occurs. In addition, the user can intuitively grasp whether the closing timing should be adjusted by the display position and the display color.

  Here, in order to facilitate understanding, the index data is not superimposed, but the index data may be superimposed to allow the user to quantitatively grasp the degree of crosstalk. Similarly to the guide data acquisition unit 160 of the first embodiment described above, one or more selected from the group of the first guide data, the second guide data, the third guide data, and the fourth guide data are not shown. The guide data acquisition unit 360 may acquire the information from the memory by storing the information in advance in the memory.

(3D image display method)
FIG. 14 is a flowchart for explaining specific processing of the stereoscopic video display method according to the second embodiment.

  When the video acquisition unit 150 acquires the left-eye video data and the right-eye video data having horizontal parallax (S400), the guide data acquisition unit 360 includes the first guide data, the second guide data, the third guide data, and the first guide data. 4 guide data is acquired (S402).

  Then, the video processing unit 362 uses the first left eye guide data 380a as the first guide data and the second guide data acquired in the guide data acquisition step S402 as the earliest left eye video data L1 among the left set data 370a. In addition, the second left-eye guide data 380c as the third guide data and the fourth guide data is changed to the last left-eye video data L2 in the left set data 370a, and the first guide data and the first guide data as the second guide data. The right eye guide data 380b is used as the earliest right eye video data R1 of the right set data 370b, and the second right eye guide data 380d as the third guide data and the fourth guide data is used as the last of the right set data 370b. Each is superimposed on the right-eye video data R2 (S404).

  Then, the display control unit 164 causes the display 166 to alternately display the left set data and the right set data generated in the data superimposing step S404 (S406).

  Here, when the opening / closing timing of the left shutter of the electronic shutter glasses 120 is adjusted (YES in S408), the right shutter is kept closed during the adjustment period (S410). Then, the shutter signal adjustment unit 172 adjusts the opening timing of the shutter signal for the left shutter according to the operation input through the operation unit 170 by the user (S412), and the shutter signal for the left shutter is displayed on the display 166. The displayed second right eye guide data 380d disappears and the first left eye guide data 380a remains. Further, the shutter signal adjustment unit 172 adjusts the closing timing of the shutter signal for the left shutter according to the operation input through the operation unit 170 by the user (S414), and the shutter signal for the left shutter is displayed on the display 166. The displayed first right eye guide data 380b disappears and the second left eye guide data 380c remains.

  On the other hand, when the opening / closing timing of the right shutter of the electronic shutter glasses 120 is adjusted (NO in S408), the left shutter is kept closed during the adjustment period (S416). Then, the shutter signal adjustment unit 172 adjusts the opening timing of the shutter signal for the right shutter according to the operation input through the operation unit 170 by the user (S418), and the shutter signal for the right shutter is displayed on the display 166. The displayed second left eye guide data 380c disappears and the first right eye guide data 380b remains. In addition, the shutter signal adjustment unit 172 adjusts the closing timing of the shutter signal for the right shutter according to the operation input by the user via the operation unit 170 (S420), and the shutter signal for the right shutter is displayed on the display 166. The displayed first left eye guide data 380a disappears and the second right eye guide data 380d remains.

  Then, the signal transmission unit 174 transmits the shutter signal for the left shutter and the shutter signal for the right shutter adjusted in the adjustment steps S412, 414, 418, and 420 to the electronic shutter glasses 120 (S422).

  As described above, even in the stereoscopic video display method according to the present embodiment, when the crosstalk occurs, it is only necessary to adjust the opening timing of the electronic shutter glasses 120 just by looking at the display 166. It becomes possible for the user to intuitively grasp whether the closing timing should be adjusted.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
