Description

  The present invention relates to a method for recording / reproducing a left-eye and right-eye video signal constituting a stereoscopic video as a single stereoscopic video composite signal with high image quality, and a stereoscopic video display apparatus for displaying the same.

As shown in FIGS. 12 (a) and 12 (b), a conventional 3D image display apparatus without glasses that displays a 3D image to a viewer has a left-eye image and a right-eye image arranged side by side in the vertical direction of the screen. a lenticular method and parallax barrier method for displaying, as shown in FIG. 13, but device displayed side by side for each horizontal line left-eye image and right-eye video in the horizontal direction of the screen (Patent Document 1) is known The stereoscopic video display apparatus described in this publication divides all horizontal scanning lines of the display panel into odd lines and even lines, and displays the left-eye and right-eye videos on each line, which is viewed by optical means. 3D images are distributed to the left and right eyes of the person, and this display method solves the problem of halving the horizontal resolution, which was a drawback of the lenticular method and the parallax barrier method. However, the problem remains that the vertical resolution is halved.

  In addition, in order to reduce flicker, the video signal used in the above conventional stereoscopic video display device uses a non-interlace video signal obtained by combining the left and right video signals for the purpose of simultaneously displaying the left and right videos, and the left-eye camera video. The signal and the right-eye camera video signal are generally recorded, stored, and reproduced as a single video signal.

  FIG. 14 shows an example of a conventional general video signal synthesizing method, in which an odd field of a right-eye interlaced video signal and an even field of a right-eye interlaced video signal are alternately recorded (referred to as a field sequence method). Thus, a single 3D image synthesis signal is obtained. The advantage of this method is that recording / reproduction can be performed by one video recording / reproducing apparatus, video editing work can be performed by one editing apparatus, and video storage management can be unified.

  However, in such a conventional stereoscopic video display apparatus and stereoscopic video signal recording / reproducing method, as shown in FIG. 14C, each field of the recorded stereoscopic video composite signal is an odd field or an even field. Therefore, there is a problem that the vertical resolution is halved. Furthermore, since the information in the time axis direction jumps over the field one by one (displaying 1/60 sec → displaying 1/30 sec), there is a problem that it is difficult to display a moving image more smoothly.

  In particular, when displaying the 3D image composite signal using the 3D image display device, as shown in FIG. 14D, the left and right images shifted by one field are displayed at the same time. There is a time contradiction. Further, even though the stereoscopic video display device displays a non-interlaced signal, the left and right eyes display a video whose vertical resolution is halved. In addition, there has been a problem that vertical shift occurs between the odd field and the even field due to the interlace signal in the left and right images.

JP-A-10-63199

The present invention was devised in view of the current situation, and the object of the present invention is to display all the left and right eye video information that could not be realized by a conventional stereoscopic video system, It is an object of the present invention to provide a completely new 3D image display device that can perform unified management of 3D images during reproduction.

To achieve the above object, a first aspect of the present invention, the recording of stereoscopic image synthesis signal is transmitted as one of the non-interlaced by synthesizing the left-eye video signal constituting a stereoscopic video and the video signal for the right eye, recorded A stereoscopic display to be played back is a display and display device, and a right-eye video signal and a left-eye video signal are arranged on odd-numbered lines and even-numbered lines of one frame video to be displayed, and for each frame, By alternating the lines of the video signal for the right eye and the video signal for the left eye, the left and right video signals are interlaced, and the video signal for the right eye and the video signal for the left eye are simultaneously displayed for each frame using the light source and the polarizing filter for the light source.

  Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. As long as there is no description of this, it is not restricted to this Example.

  As shown in FIG. 1, the stereoscopic video system of the present invention includes a right-eye camera 11 and a left-eye camera 12 that shoot left and right videos, a synchronization control device 14 that controls the right-eye camera 11, an identification information insertion device 13, The video composition signal recording / conversion device 10, the three-dimensional signal recording / reproducing device 20, the three-dimensional video display device 60, and an identification information detecting device 90 for controlling the same are configured.

  In this embodiment, the left and right eye cameras 11 and 12 are interlaced cameras. However, this camera may be a non-interlaced or high-vision camera, and uses a still image digital camera. It doesn't matter. Further, instead of using two cameras, a stereoscopic video camera that captures left and right images at the same time on one camera may be used. Of course, it may be a computer graphic (CG device) having a function of drawing left and right images by a computer.

  The left and right video TV cameras 11 and 12 use a control signal from the synchronization control device 14 to set the relationship between the left video signal and the right video signal on the time axis to any combination of even field / odd field or odd field / even field. Control is performed by the synchronization control device 14 so as to maintain the relationship, and synchronization control is performed so that the time axes always coincide. In the conventional method that does not include this synchronization control device 14, as shown in FIGS. 15 (a) and 15 (b), the video output of the left and right cameras is designed to always start from the odd field. When converting to a signal, there is a problem in that images with the timings of the left and right camera images being shifted are combined.

  FIG. 2 (a) shows a specific example of a method for synchronizing two cameras. The two cameras are operated in the external synchronization mode, and as the external synchronization signals, a vertical synchronization signal shifted by one vertical synchronization (field) is supplied from the synchronization control device 14 to the left-eye camera.

  Since the video output from each of the two cameras operates based on the external synchronization signal, it is output to the stereoscopic video composite signal recording / converting device 10 with a phase shift of one field.

  FIG. 2B shows a specific example of the synchronization method of the integrated camera having the right and left eye CCDs. By shifting the timing of the vertical sync signal supplied to each CCD from the sync signal generator built in the camera by one field, the video output from each CCD becomes a combination of odd and even fields and 3D video synthesis It is output to the signal recording conversion device 10.

  FIG. 3 shows a situation in which the conventional problem is solved by using this synchronization control device 14. At the same time, the synchronization control device 14 supplies a reference signal for inserting identification information to the identification information inserting device 13. That is, the synchronization control device 14 also has a function as a synchronization signal generator that serves as a reference for the entire system.

  That is, as shown in FIG. 3, the stereoscopic video synthesis signal recording / conversion apparatus 10 divides the left and right videos into odd and even lines and synthesizes them (line-divided stereoscopic signal), thereby producing a non-interlaced stereoscopic video synthesis. It converts into a signal image | video (refer FIG.3 (c)). This 3D image synthesized signal image can be directly viewed on a live camera image on the 3D image display device 60 capable of displaying a line-divided 3D signal.

  The non-interlaced stereoscopic signal recording / reproducing device 20 records the stereoscopic video composite signal converted into the line-divided stereoscopic signal by a non-interlace method and superimposes the identification signal from the identification information insertion device 13 on a part of the image. Inserted in the video blanking period (synchronization signal period).

  The non-interlaced stereoscopic signal recording / reproducing apparatus 20 is connected to a recording medium 40 such as a Blu-ray recorder, D-VHS, hard disk drive, DVD disk, etc., and the stereoscopic video composite signal is stored in a high-density and large-capacity medium. It is configured as follows.

  In addition, in order to record and save the video by compressing the video using a known method such as MPEG, the stereoscopic signal conversion processing device 10 divides the left and right video signals into one frame as shown in FIG. A 3D video composite signal output to be synthesized (upper and lower divided 3D signal) is provided, compressed by the MPEG video compression device 30, and recorded together with an identification signal in the MPEG video recording / playback device 50. At this time, if the conversion is performed by the method disclosed in the PCT application (PCT / JP03 / 05712) filed earlier by the present inventor, it is possible to prevent image distortion due to video compression / expansion.

  The MPEG video recording / reproducing apparatus 50 is connected to a recording medium 40 such as a Blu-ray recorder, D-VHS, hard disk drive, DVD disk, etc., and the stereoscopic video composite signal is stored in a high-density and large-capacity medium. . Of course, stereoscopic video content can be created in the same format as the recording medium, and can also be used for stereoscopic video broadcasting.

  These recording media are reproduced by the non-interlaced stereoscopic signal recording / reproducing device 20 or the MPEG video recording / reproducing device 50, converted into a video signal for the stereoscopic display device by the stereoscopic video composite signal display converting device 80, It is displayed on the video display device 60. In this embodiment, the stereoscopic video display device 60 capable of displaying the line-divided stereoscopic signal is used. However, in the present invention, the stereoscopic video display means is not particularly limited, and any system can be used. Can even be used.

  In the case of the MPEG video recording / reproducing apparatus 50, a stereoscopic video signal needs to be decompressed. Therefore, the MPEG video decompressing apparatus 70 decompresses the stereoscopic video signal, and the stereoscopic video composite signal display conversion apparatus 80 converts it to a line-divided stereoscopic signal. The converted image is displayed on the stereoscopic image display device 60.

  The stereoscopic video composite signal display conversion device 80 outputs a stereoscopic video signal for display to the stereoscopic video display device 60 and simultaneously sends an identification signal to the identification information detection device 90 to control light source and signal processing of the stereoscopic video display device 60. For example, high-quality 3D image display can be realized.

  Further, the stereoscopic video composite signal display conversion device 80 is configured to have a function of outputting a right video signal or a left video signal among the stereoscopic video composite signals, and is added to a conventional flat (2D) video display device 61. Is also supported.

  The above description is the flow from shooting to display by the system of the present invention, and the mechanism for recording / reproducing high-quality stereoscopic video will be described in detail below.

  As shown in FIGS. 3A and 3B, the stereoscopic signal recording / conversion device 10 is a series of interlaced video signals R1EL10, R20 inputted from the left and right television cameras 11, 12 every 1/60 seconds. , L1E, R2E, L20, L30, L2E (in this specification, L is a video for the left eye, R is a video for the right eye, a numeral is a frame number, O is an odd field, and E is an even field).

  Then, the stereoscopic signal recording / conversion processing apparatus 10 converts a signal starting from L and a set of two non-interlaced stereoscopic video synthesized signals starting from R as a stereoscopic video synthesized signal shown in FIG. At this time, the identification information insertion device 13 superimposes or inserts the identification signal in an area outside the video display by changing the identification signal depending on whether it starts with L or R. By performing such a conversion process, as shown in FIG. 3C, the three-dimensional video composite signal sent to the recording apparatus is converted into a series of signal formats for all the video signals from the camera. There is no time axis shift of the left and right images as in the method, and field skipping as shown in FIG. 16, which is the conventional method, does not occur, so that high-quality 3D image signals can be recorded.

  Next, the relationship on the time axis of the video signal of the left and right video camera is not controlled by any combination of even field / odd field or odd field / even field, and the relationship between odd field or even field The case of receiving by will be described.

  In this case, as shown in FIG. 12, the stereoscopic video recording / conversion apparatus 10 converts the video signal obtained by combining the odd-numbered fields and the even-numbered fields of the left and right video signals into an L signal like the stereoscopic video composite signal of FIG. Or a pair of non-interlaced stereoscopic video composite signals starting from R or a pair of non-interlaced stereoscopic video composite signals always starting from R, as shown in FIG. At the time of reproduction, the stereoscopic video composite signal display conversion device 80 converts the video signal starting from L and a set of two non-interlaced stereoscopic video composite signals starting from R.

  12 and 13, the time axis of the left and right images is not shifted, and a stereoscopic video signal can be recorded without causing field skipping. However, compared to the method shown in FIG. Since the cameras use the same odd lines or even lines, strictly equal vertical resolution cannot be obtained, and there is also a vertical shift. For this reason, the method shown in FIG. 3 is most suitable for realizing the present invention.

  When recording is performed using a known video compression technique, the compression processing is performed in units of frames. Therefore, the left and right videos as shown in FIG. 3 are combined into odd and even lines (line division). If it is used for (stereo signal), odd and even lines are mixed, so it becomes irreversible (does not return to the base), and this recording method cannot be used. Therefore, in the present invention, the stereoscopic signal recording conversion processing apparatus 10 performs the signal conversion processing shown in FIG.

  That is, as shown in FIGS. 5 (a) and 5 (b), the stereoscopic signal recording conversion processing apparatus 10 is a series of interlaced video signals input from the left and right television cameras 11 and 12 every 1/60 seconds. Receive.

  Then, in the stereoscopic signal recording conversion processing apparatus 10, as shown in FIG. 5C, a set of two sheets each having a top half of R and a bottom half of L, or a top half of L and a bottom half of R. Convert to interlaced 3D video composite signal. At this time, as shown in FIG. 5D, the video signals from the left and right cameras are interlaced in line spacing, and the left and right video signals are combined into a single non-interlaced signal without being thinned out. At this time, the identification information insertion device 13 changes and superimposes or inserts an identification signal in a region outside the video display. By recording using this conversion method, it is possible to use a known MPEG video compression apparatus 30, MPEG video recording / reproducing apparatus 40, and MPEG video expansion apparatus 70. However, if a conventional method such as that described in Japanese Patent Laid-Open No. 10-257526 is used, the reversibility of the boundary between the upper and lower images is lost and the image is disturbed. Therefore, the LR is applied by the method previously filed by the inventor. If one of the images is recorded upside down or horizontally reversed, the boundary image that is a problem during video compression / expansion will not be disturbed.

  In the case of recording / reproducing a planar (2D) video signal, the odd field and the even field are converted into a frame signal synthesized as it is, and recorded as a non-interlaced signal together with an identification signal indicating that it is a 2D video, or Then, the interlace signal is line-interpolated and recorded as a non-interlace signal.

  Next, a mechanism for displaying a high-quality stereoscopic video using the present invention will be described in detail.

  The configuration of the stereoscopic video display device is shown in FIGS. In FIG. 6, reference numeral 62 denotes a liquid crystal display element, and a Fresnel lens 63 is disposed on the back side of the liquid crystal display element 62 at a predetermined distance. The Fresnel lens 63 has a concentric concave and convex lens surface on one side surface, and is arranged to emit light incident from the central focal point on the back side of the Fresnel lens as substantially parallel light.

  A diffusion plate 64 having the capability of diffusing only in the vertical direction is attached to the front surface of the liquid crystal display element 62, and light that has passed through the liquid crystal display element 62 is emitted to the viewer side through the diffusion plate 64.

  Reference numeral 65 denotes a backlight light source for irradiating the liquid crystal display element 62 from the back surface. In this embodiment, as shown in FIG. 7, the backlight light source 65 is divided into four blocks that can be controlled individually.

  The backlight light source block 65UR and the backlight light source block 65DR are light sources for the viewer's right eye zone, and the backlight light source block 65UL and the backlight light source block 65DL are light sources for the viewer's left eye zone.

  On the front side (irradiation side) of the backlight light source 65, a right-eye polarizing filter section 66U and a left-eye polarizing filter 66D are arranged.

  These right-eye and left-eye polarization filters 66U and 66D are configured as linear polarization filters whose polarization directions are orthogonal to each other, and are, for example, a right-upward polarization plane and a left-upward polarization plane.

  Further, the liquid crystal display element 62 is of a light transmission type, and has two polarizing filters 621 and 622 disposed on both surfaces of the liquid crystal panel 620 as shown in FIG.

  In the liquid crystal panel 620, for example, a liquid crystal twisted 90 degrees is accommodated in a pair of alignment films, and when no voltage is applied between the pair of alignment films, incident light is rotated 90 degrees and emitted, and when a voltage is applied The incident light is emitted as it is without rotating. The two polarizing filters 621 and 622 are alternately arranged with linearly polarizing filter line portions La and Lb that are orthogonal to each other for each horizontal line of the liquid crystal panel, and the light source side (rear side) and the observation side (front side). ) Of the linearly polarizing filter line portions La and Lb that are opposed to each other.

  Accordingly, since the light from the right-eye polarizing filter unit 66U or the left-eye polarizing filter unit 66D enters only from the linear polarization filter line portions La and Lb having the same polarization plane, the light enters every other horizontal line. Thus, each incident light is transmitted when no voltage is applied, and is blocked when a voltage is applied.

  Further, the liquid crystal panel 620 of the liquid crystal display element 62 is configured so that video information for the right eye and the left eye is alternately displayed for each horizontal line in accordance with the light transmission lines of the two polarizing filters 621 and 622. Has been.

  For this reason, if the viewer looks at the liquid crystal display element 62 at a clear viewing distance, only the right-eye image is incident on the right eye 70R and the left-eye image is incident on the left eye 70L independently, based on binocular parallax. It can be viewed as a 3D image by 3D perception.

  In the example of the liquid crystal display element shown in FIG. 7, two polarizing filters 621 and 622 arranged on both sides of the liquid crystal panel 620 are linearly polarizing filter line portions orthogonal to each other for each horizontal line of the liquid crystal panel. La and Lb are arranged alternately, but considering the cost, each polarization filter uses a linear polarization filter having the same polarization plane, and the polarization angles of both polarization filters are set in directions orthogonal to each other. it can. In this case, the same effect can be obtained by arranging a half-wave plate in the horizontal direction of the liquid crystal panel 620 in the polarizing filter on the backlight source side.

  Next, as shown in FIG. 4A and FIG. 7, the backlight light source 65 used in the present invention is composed of four blocks (five white LEDs) arranged in two stages, upper and lower, and left and right with the center as a boundary. The upper stage portions 65UR and 65UL and the lower stage portions 65DR and 65DL are arranged side by side in the left and right and upper and lower two stages, and these LED blocks are individually configured to be capable of split lighting control.

  An upper stage polarizing filter 66U and a lower stage polarizing filter 66D are arranged at positions corresponding to the LED blocks of the upper stage parts 65UR and 65UL and the lower stage parts 65DR and 65DL. These polarization filters 66U and 66D are configured as polarization filters whose polarization directions are orthogonal to each other (FIG. 4C), and have, for example, a right-down polarization plane and a left-down polarization plane.

  The light source lighting control unit 105 receives the signal from the identification signal control unit 103 and, as shown in FIG. 4A, causes the upper left 65UR and the lower right 65DL of the LED block to emit light at timing 1, and at the next timing 2. The lower left 65DR and upper right 65UL of the LED block are caused to emit light. This switching is performed by the identification information signal superimposed and inserted together with the stereoscopic video synthesis signal, and the display timing of the stereoscopic video synthesis signal displayed on the liquid crystal display device 62 is synchronized.

  As shown in FIG. 4B, the liquid crystal display panel 62 displays the stereoscopic video composite signal 1 at timing 1 and the stereoscopic video composite signal 2 at timing 2 under the control of the video display control means 104.

  At this time, as shown in FIG. 4A, the backlight light source 65 is synchronized with the display conversion timing of the liquid crystal display panel 62, and the upper right irradiation unit 65UR, the lower left irradiation unit 65DL, and the lower right The irradiation unit 65DR and the upper left irradiation unit 65UL are alternately lit. In this embodiment, the viewer 70 is positioned at the center of the front of the stereoscopic image display device 60, and five LEDs are blinking on the center line of both eyes.

  As shown in FIG. 7, at the timing 1, the viewer's left eye 70 </ b> L arranged in the left eye zone is emitted from the lower right irradiation unit 65 </ b> DL of the backlight light source 65, passes through the left eye polarizing filter 66 </ b> D, An image transmitted through the left display polarization region of the polarization filter 621 is incident. In the viewer's right eye 70R arranged in the right eye zone, an image in which the light from the upper left irradiation unit 65UR is transmitted through the right eye polarizing filter 66U and the left display polarizing region of the polarizing filter 621 is transmitted. Incident.

  Subsequently, at the timing 2, the left eye 70L of the viewer arranged in the left eye zone is emitted from the upper right irradiation unit 65UL of the backlight light source 65, passes through the left eye polarizing filter 66U, and is displayed on the left side of the polarizing filter 621. The image that has passed through the polarizing region is incident. In addition, an image in which light from the lower left irradiation unit 65DR is transmitted through the right-eye polarizing filter 66D and through the left display polarizing region of the polarizing filter 621 is incident on the viewer's right eye 70R arranged in the right-eye zone. Is done.

  At this time, since the switching timing of the backlight light source 65 and the switching timing of the stereoscopic video display are synchronized, the viewer 70 displays them on the same horizontal line of the liquid crystal display element at timing 1 and timing 2. Since the stereoscopic video signal is alternately displayed, the left and right eyes of the viewer 70 can see the video on all the scanning lines.

  Further, when displaying a 2D image on the stereoscopic video display device 60 according to the present embodiment, switching of the backlight light source is stopped based on the 2D recognition information signal sent from the identification information detection device, and all parts are displayed. By turning on, it is possible to display a bright 2D moving image with high resolution. In the future, in the process in which stereoscopic video is used for broadcasting, etc., it is possible to automatically switch between 2D / 3D modes by an identification information signal in a situation where commercials are 3D broadcasts and general programs are 2D broadcasts. it can.

  As described above, in the conventional example, the polarization plane of the light source emitted from the backlight light source 65 is fixed to either the lower right or the lower left, and thus one horizontal line for displaying left and right images on the liquid crystal display element 62. The positions (odd lines and even lines) have been determined, but in this embodiment, the liquid crystal display element 62 is switched by simultaneously switching the polarization plane of the light source emitted from the backlight light source 65 and the display position of the video signal to be displayed. The left and right images can be displayed alternately on the same horizontal line, and the vertical resolution can be increased.

  In this embodiment, the upper and lower two-stage white LED arrays and the linearly polarizing filter are combined as the backlight light source, but circularly polarized light may be used instead of the linearly polarized light. A method may be used in which a liquid crystal panel having a polarization angle switching function is disposed in front of the light source in a horizontal row of light sources, and the polarization angle is changed with the central portion as a boundary.

  Further, as shown in FIG. 9C, polarizing filters having different deflection angles are arranged in the white LED blocks arranged as shown in FIG. 9A, and the same effect is obtained by performing individual control of the light source. be able to.

  Further, as shown in FIG. 8, the upper right 65UL and the upper left 65UR of the LED block are caused to emit light at the timing 1 and the LED at the next timing 2 by a method constituted by the combination of the backlight light source a and the polarizing filter c. The lower right 65DL and the lower right 65DR of the block are caused to emit light. A similar result can be obtained by performing this switching by using the identification information signal superimposed and inserted together with the stereoscopic video synthesis signal and synchronizing the display timing of the stereoscopic video synthesis signal displayed on the liquid crystal display device 62.

  In the present invention, the display means is not particularly limited, and in addition to the transmissive liquid crystal display device described above, a reflective or direct-view liquid crystal display device, a plasma display device, an EL display device, or the like is used. Is also possible.
