Description

  The present invention relates to a stereoscopic video display apparatus, an information processing apparatus, and a stereoscopic video display method capable of forming a stereoscopic video with binocular parallax through a display.

  In recent years, LCDs such as liquid crystal displays (LCDs) and organic EL (Electro Luminescence) displays have been increasing in screen size, but they are still used for events where large numbers of people gather. When installing a display on the outer wall of the display, the size of the display may be insufficient. Therefore, a configuration in which a video is displayed with a multi-screen combining a plurality of displays as one screen is conceivable.

  However, as shown in FIG. 14A, the general display 10 includes a speaker, an operation unit, and the like for outputting audio accompanying the video in the lower frame unit 14 below the display surface 12. There is. The lower frame portion 14 cannot display an image. Therefore, for example, as shown in FIG. 14 (b), when two displays 10 (indicated by 10a and 10b in FIG. 14 (b)) are arranged side by side as they are to form a multi-screen, the displays are displayed on the display surfaces 12a and 12b. If the lower frame portion 14a of 10a is interposed and one video is displayed on the display surfaces 12a and 12b, the continuity of the video is greatly impaired.

  Therefore, as shown in FIG. 14C, for example, a multi-screen can be configured so that the lower frame portion 14 does not exist between the display surfaces 12 by inverting the display 10 a to be arranged on the upper and lower and left and right sides. Conceivable. However, when a part of the display 10a is arranged upside down and left and right in this way, the video displayed on the display surface 12a of the display 10a is in a state where the top and bottom and left and right are reversed, which is intended. There is a problem that the image cannot be expressed.

  Therefore, a changeover switch that can switch between the normal display and the reverse display obtained by inverting the normal display in the vertical direction is provided, and when the reverse display is instructed through the changeover switch, the image signal corresponding to the display screen is sequentially applied from the last address A technique (for example, Patent Document 1) is disclosed in which reading is performed and the highest-order bit and the lowest-order bit of the read signal unit are inverted and displayed on a display (display surface). By using such a technique, if the video is reversed and displayed on the display surface 12a of the display 10a that is flipped up and down, left and right, the video is continuous in the normal direction on the display surface 12a and the display surface 12b, and the user feels uncomfortable. You can enjoy images without.

  On the other hand, in recent years, stereoscopic image display devices that display two or more images having parallax on the display surface of the display and perceive the user (observer) as if the object exists stereoscopically have attracted attention. ing.

  Various proposals have been made for techniques for realizing such video display. For example, polarization filter methods such as μpol and Xpol (registered trademark) have been proposed. In a stereoscopic image display apparatus that employs a polarizing filter system, two types of polarizing filters having different polarization characteristics are arranged in a row (for each display line) on the display surface of the display. Here, when the polarization characteristics are different, when linearly polarized light is used for the polarization filter, the polarization of one polarization filter and the other polarization filter is orthogonal, for example. When circular polarization is used, one polarization filter Means left polarization and the other polarization filter is right polarization. Then, the left eye video data and the right eye video data are displayed by displaying the left eye video data on the display line on which one polarization filter is arranged and the right eye video data on the display line on which the other polarization filter is arranged. Are displayed at the same time in a state of being alternately arranged. Then, the user can visually recognize the left-eye image shown on the alternate display line with the left eye and the right-eye image with the right eye through the polarizing glasses, and perceive a stereoscopic image based on binocular parallax.

  The binocular parallax mentioned above is called Binocular parallax, which senses the depth at the angle (convergence angle) where each eyeball faces, represented by the so-called eyeball phenomenon of the right eye and the left eye when looking at nearby objects, There is a so-called Binocular disparity that perceives a solid because the position of the left and right eyeballs of human beings is different, and the images projected on the retina of each eyeball are different when observing a solid object. Binocular parallax.

  A stereoscopic image display apparatus that employs a polarizing filter system has the advantage that the structure of polarized glasses used by the user is simple. However, since two images are required to visually recognize one image, the stereoscopic image display apparatus is relatively In addition, there is a disadvantage that the number of display pixels is reduced. Therefore, in a stereoscopic video display apparatus, a configuration in which a multi-screen combining a plurality of displays described above is used as one screen for displaying video can be considered.

  By the way, the display of the stereoscopic image display device adopting the polarization filter method is an even number in order to correspond to an interlace method, a display standard such as VGA (Video Graphics Array), and a video standard such as HDTV (High Definition TeleVision). It has a display line. Therefore, if one polarizing filter is disposed on the uppermost display line of the display, the other polarizing filter is disposed on the lowermost display line.

  Here, in the stereoscopic image display device, when an attempt is made to arrange some of the plurality of displays upside down, left and right, the above-described technique of Patent Document 1 is used to convert the video data upside down. If the display order is reversed and the display is reversed on the display that flips up and down and left and right, the correspondence between the left-eye image and right-eye image and the display line shifts, and the user sees the display that is up-down and left-right reversed. In such a case, it becomes impossible to perceive an effective stereoscopic image.

  In view of such a problem, the present invention provides a stereoscopic video display apparatus and information capable of realizing effective stereoscopic display by binocular parallax even when reversed display is performed on a display that is inverted vertically and horizontally. An object of the present invention is to provide a processing device and a stereoscopic video display method.

In order to solve the above-described problem, a stereoscopic image display device according to the present invention includes a first display in which first display lines and second display lines having polarization characteristics different from those of the first display lines are alternately arranged. And a second display that is juxtaposed on the upper side of the first display in a state where the first display is vertically and horizontally reversed , and performs a reversed display in which the normal display is reversed vertically and horizontally , and the first and second In order to realize stereoscopic viewing by binocular parallax in the display, one of left eye video data to be viewed by the left eye or right eye video data to be viewed by the right eye is arranged in a line unit at a position corresponding to the first display line A data acquisition unit for acquiring stereoscopic display data in which the other is arranged in units of lines at positions corresponding to the second display lines, and one of the first display and the second display. A data delay unit that delays the stereoscopic display data for display on the odd number lines and the other display of the first or second display sequentially outputs the stereoscopic display data to the first or second display. One of the displays is provided with a video output unit that sequentially outputs the delayed stereoscopic display data.

  The stereoscopic image display device further includes a line detection unit that detects the first line of the stereoscopic display data, and the data delay unit is generated when the stereoscopic display data is delayed by an odd number of lines when the first line is detected. Arbitrary data may be set in blank areas for odd lines.

In order to solve the above problems, an information processing apparatus according to the present invention includes a first display in which first display lines and second display lines having different polarization characteristics from the first display lines are alternately juxtaposed. A second display that is arranged in the upper part of the first display in a state of being inverted vertically and horizontally and that performs reverse display in which the normal display is inverted vertically and horizontally, and stereoscopic viewing by binocular parallax. 3D video to be displayed on one of the first and second displays, and a video holding unit that holds stereoscopic video data in which left-eye video data and right-eye video data are divided and formed. The first stereoscopic display data is obtained by alternately juxtaposing the horizontal lines so that the left eye video data and the right eye video data in the data correspond to the first display line and the second display line, respectively. The left-eye video data and the right-eye video data in the stereoscopic video data are displayed on the second display line and the first display line, respectively. A line sequential unit that outputs the second stereoscopic display data by alternately juxtaposing the horizontal lines is provided.

In order to solve the above-described problem, the stereoscopic image display method according to the present invention includes a first display in which first display lines and second display lines having polarization characteristics different from those of the first display lines are alternately juxtaposed. A stereoscopic display using binocular parallax in a second display that is arranged in the upper part of the first display in an inverted state in the up / down / left / right direction and performs the inverted display by inverting the normal display in the up / down / left / right direction. Therefore, one of the left-eye video data to be visually recognized by the left eye or the right-eye video data to be visually recognized by the right eye is arranged in a line unit at a position corresponding to the first display line, and the other is the second display line. 3D display data arranged in line units at a position corresponding to, and 3D display data for displaying on one of the first or second displays is an odd line. 3D display data is sequentially output to the other of the first or second displays, and the delayed 3D display data is sequentially output to one of the first or second displays. It is characterized by doing.

In order to solve the above problems, another stereoscopic image display method of the present invention holds stereoscopic video data in which left-eye video data and right-eye video data for realizing stereoscopic viewing by binocular parallax are divided and formed.

  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)
FIG. 1 is a diagram showing a usage pattern of the stereoscopic image display apparatus 100 according to the first embodiment. As shown in FIG. 1, the stereoscopic image display apparatus 100 is configured to include a plurality of (two in this embodiment) displays 120 (indicated by 120A and 120B in FIG. 1), and the display 120B is an upper part of the display 120A. Are juxtaposed. In order to maintain the aspect ratio of the display 120, the stereoscopic image display apparatus 100 often has n ² (n is an integer, for example, 4) displays 120. In this case, the plurality of displays 120 are provided. One display group (plural displays 120B) when divided into two according to the application is juxtaposed above the other display group (plural displays 120A), but here, for convenience of explanation, the display 120A and the display One 120B is provided.

  In general, a lower frame portion 122 (shown by 122A and 122B in FIG. 1) of the display 120 is provided with a speaker 140 (shown by 140a to 140d in FIG. 1) and an operation unit (shown by 122a and 122B). In many cases, the lower frame portion 122 cannot display an image. Therefore, the stereoscopic image display apparatus 100 arranges the display 120B in an inverted state in the up / down / left / right direction on the top of the display 120A, so that the lower frame portion is provided between the display surface 124A of the display 120A and the display surface 124B of the display 120B. The image discontinuity due to the presence of 122 is avoided.

  When displaying a video on the display 120 </ b> A, the stereoscopic video display device 100 displays the video in a vertical orientation (normal display) so that the user can easily view the video.

  On the other hand, the stereoscopic video display device 100 outputs video data (stereoscopic display data) in the same order as in the case of the display 120A when displaying video on the display 120B juxtaposed upside down on the top of the display 120A. Then, the image is displayed in a state where the vertical and horizontal positions are reversed. At this time, if the stereoscopic display data is output in the reverse order to the normal display, the correspondence relationship between the left eye video and the right eye video and the display line is shifted, and the user cannot perceive an effective stereoscopic video.

  Therefore, in the present embodiment, even when the user visually recognizes the display 120B that is flipped up and down and left and right as described above, the image is grasped by a normal display direction and effective stereoscopic display by binocular parallax. The stereoscopic video display device 100 and the stereoscopic video display method that can be performed will be described. In the present embodiment, the binocular parallax includes one or both of the above-described Binocular parallax and Binocular disparity. In the following, the display 120A (hereinafter referred to as a normal display 120A for ease of understanding) is used as the first display, and the display 120B (hereinafter referred to as the reversal display 120B for ease of understanding) as the second display. However, the present invention is not limited to this case, and the display 120B can be applied as the first display and the display 120A can be applied as the second display.

(3D image display device 100)
FIG. 2 is a functional block diagram illustrating schematic functions of the stereoscopic video display apparatus 100 according to the first embodiment. As shown in FIG. 2, the stereoscopic video display apparatus 100 includes a data acquisition unit 150, a data processing unit 152, a line detection unit 154, a data delay unit 156, a video output unit 158, and a plurality of displays 120 (here). Then, it is comprised including the normal display 120A and the inversion display 120B). Although the case where the stereoscopic video display device 100 is configured to include the display 120 will be described here, the stereoscopic video display device 100 and the display 120 can be configured separately.

  The data acquisition unit 150 acquires stereoscopic display data broadcast from the external broadcasting station 104 via the antenna 106. The data acquisition unit 150 also receives stereoscopic display data from an external server 112 via a recording medium 108 such as a DVD (Digital Versatile Disc) or BD (Blu-ray Disc), or a communication network (Internet or LAN) 110. Can be acquired.

  Here, as the stereoscopic display data, in order to realize stereoscopic vision by binocular parallax on the display 120, one of the left-eye video data to be visually recognized by the left eye and the right-eye video data to be visually recognized by the right eye is first displayed on the display 120. A line unit is disposed at a position corresponding to a line, and the other line unit is disposed at a position corresponding to a second display line of the display 120 in line units.

  In the present embodiment, the data acquisition unit 150 directly acquires data already in the form of stereoscopic display data, but the stereoscopic video data (side-by-side) associated with the left-eye video data and the right-eye video data being separated. In the case of acquiring a method or a top-and-bottom method), the acquired stereoscopic video data can be rearranged in line units to generate stereoscopic display data (line sequential processing).

  FIG. 3 is an explanatory diagram for explaining a process of generating the stereoscopic display data 202 from the stereoscopic video data 200. For example, top-and-bottom stereoscopic video data 200 as shown in FIG. 3 is associated in a state where left-eye video data 200a and right-eye video data 200b for realizing stereoscopic viewing by binocular parallax are separated. . Therefore, when the data acquisition unit 150 acquires the top-and-bottom stereoscopic video data 200, one of the left-eye video data 200a and the right-eye video data 200b corresponds to the first display line of the display 120. The other video data is arranged in a line unit at a position corresponding to the second display line, that is, the data acquisition unit 150, as shown in FIG. The stereoscopic display data 202 is generated by alternately juxtaposing the right-eye video data 200b in line units.

  Hereinafter, the data in the line unit of the left-eye video data 200a is represented by the left-eye line data (shown by adding a line number to the code LD as shown in FIG. 3) and the data in the line unit of the right-eye video data 200b is represented by the right-eye line Data (referred to as RD with a line number as shown in FIG. 3). Here, a case where the total number of the left eye line data and the total number of the right eye line data are set to 540 will be described as an example.

  Further, the data acquisition unit 150 can specify the left-eye video, the right-eye video, the display start position, and the like of the data when the acquisition source of the stereoscopic video data or the stereoscopic display data is a moving image transmitted from the broadcast station 104 or the like. A synchronization signal which is a simple signal is also acquired. When the stereoscopic video data or stereoscopic display data acquired by the data acquisition unit 150 is a still image acquired from the external server 112 via the communication network 110, the left-eye video, right-eye video, and display start of the data are displayed. Position information indicating the position and the like is also acquired. The data acquisition unit 150 outputs the acquired synchronization signal directly to the normal display 120A and the reverse display 120B.

  The data processing unit 152 performs RGB processing (γ correction and color correction), enhancement processing, noise reduction processing, and the like on the stereoscopic display data acquired by the data acquisition unit 150.

  When the data acquisition unit 150 acquires stereoscopic display data from the broadcast station 104, the line detection unit 154 detects the arrival timing of the first line of the stereoscopic display data based on a synchronization signal accompanying the stereoscopic display data. The detection result is output to the data delay unit 156.

  The data delay unit 156 delays the stereoscopic display data to be displayed on the reverse display 120B by an odd number of lines. The data delay unit 156 is configured by flip-flop circuits having the same number as the number of pixels constituting odd-numbered lines (1, 3, 5, 7... Line for one line in this embodiment) in the stereoscopic display data. For example, when the stereoscopic display data acquired by the data acquisition unit 150 is composed of one line 2200 pixels (the number of effective pixels is 1920), the number of flip-flop circuits constituting the data delay unit 156 is 2200.

  FIG. 4 is an explanatory diagram for explaining the configuration of the line detection unit 154 and the data delay unit 156. As shown in FIG. 4, the data delay unit 156 includes flip-flop circuits 160 of the same number as the number of pixels constituting one line, and stereoscopic display data is input to the D terminal of the flip-flop circuit 160, and the ck terminal. A pixel clock is input. The flip-flop circuit 160 takes in an input signal when the pixel clock rises, and outputs the result to the Q terminal. Since the Q terminal of the flip-flop circuit 160 in the data delay unit 156 is connected to the D terminal of the subsequent flip-flop circuit 160, when the pixel clock rises, the subsequent flip-flop circuit 160 is one clock before the previous stage. Input signal. That is, the data delay unit 156 functions as a shift register.

  Accordingly, the stereoscopic display data is delayed by one line by passing through the same number of flip-flop circuits 160 as the number of pixels constituting one line.

  Further, when the line detection unit 154 detects the arrival timing of the first line, the data delay unit 156 sets arbitrary data in a blank area for one line that is generated when the stereoscopic display data is delayed by one line.

  Here, referring to FIG. 4, the setting of arbitrary data for the blank area by the data delay unit 156 will be described. As shown in FIG. 4, the line detection unit 154 detects the arrival timing of the first line of the stereoscopic display data based on the synchronization signal acquired by the data acquisition unit 150, and the detection result is used as the CLR of all flip-flop circuits 160. Input to the terminal. Here, when a signal is input to the CLR terminal, the flip-flop circuit 160 sets the output of the Q terminal to 0 at the rising edge. As a result, when the line detection unit 154 detects the arrival timing of the first line, all outputs of the flip-flop circuit 160 become 0, and the number of flip-flop circuits 160 corresponding to the blank area, that is, one line, becomes data 0. Will be set. Similarly, when the line detection unit 154 detects the arrival timing of the first line, arbitrary data other than 0 is loaded into the flip-flop circuit 160 to display arbitrary data (for example, black or other colors). Data) can also be set.

  By setting arbitrary data in the blank area generated when the stereoscopic display data is delayed, the data in the blank area can be stabilized. If the blank area data is indefinite, when the blank area data is displayed on the display 120, the user cannot perceive an effective stereoscopic image, which may cause a burden on the user's eyes. Therefore, by stabilizing the data in the blank area, it is possible to reduce the burden on the user's eyes.

  Further, since all 0 data is treated as invalid data, black is displayed on the display 120. When the display 120 is a liquid crystal display, an area where no image is displayed exists between the effective display area and the bezel. The area where this image is not displayed is usually black. Therefore, by setting the data set in the blank area to data that does not feel uncomfortable with the color of the area in which this image is not displayed, that is, all zero data, the display line 126 in which the data in the blank area is displayed is displayed in this image. Can be assimilated with an area where no data is displayed, and the presence of blank area data can be made inconspicuous.

  The video output unit 158 switches between the stereoscopic display data that does not pass through the data delay unit 156 and the stereoscopic display data that passes through the data delay unit 156 and outputs the switched data to the display 120. That is, the video output unit 158 sequentially outputs the stereoscopic display data output from the data processing unit 152 to the normal display 120A as it is, and sequentially outputs the stereoscopic display data delayed through the data delay unit 156 to the reverse display 120B. Output.

  The display 120 (normal display 120A, reverse display 120B) is configured by a liquid crystal display, an organic EL display, or the like, and displays the stereoscopic display data output from the video output unit 158 on the display surface 124. As described above, the stereoscopic image display apparatus 100 has the inverted display 120B juxtaposed in the state where the normal display 120A is inverted vertically and horizontally.

  Here, the display 120 will be described with reference to FIG. 1 again. As shown in FIG. 1, the display surface 124 of the display 120 is provided with polarizing filters having different polarization characteristics every other line (for each display line). Therefore, odd-numbered display lines 126a (L1, L3, L5,..., L (n-1), n are integers and even numbers) as the first display lines and even-numbered display as the second display lines Polarization characteristics are different between the lines 126b (R2, R4,..., Rn).

  In FIG. 1, the image of the odd-numbered display line 126a corresponds to the polarizing filter on the left eye side of the polarizing glasses, and the even-numbered display line 126b corresponds to the polarizing filter on the right eye side. Data is displayed on odd numbered display lines 126a and right eye line data is displayed on even numbered display lines 126b. Here, the display 120 in which n is 1080 will be described as an example.

  As described above, the total number of display lines 126 (indicated by 126a and 126b in FIG. 1) of the display 120 is generally an even number so as to correspond to the interlace method, display standard, video standard, and the like. Therefore, when the user visually recognizes the normal display 120A in which the display lines 126 are alternately arranged in the horizontal direction (when normal display is performed), when the uppermost portion of the normal display 120A is the display line 126a (L1), The lowermost part is the display line 126b (R1080). That is, the polarization characteristics of the uppermost display line 126 and the lowermost display line 126 are different.

  FIG. 5 is an explanatory diagram for explaining a process when the video output unit 158 outputs to the normal display 120A, and FIG. 6 is a diagram for explaining a process when the video output unit 158 outputs to the reverse display 120B. It is explanatory drawing of. In FIG. 5B and FIG. 6B, AP represent pixels.

  As shown in FIG. 5A, when the stereoscopic display data 202 is normally displayed on the normal display 120 </ b> A, the video output unit 158 sequentially outputs line data according to the arrangement order of the line data in the stereoscopic display data 202. Therefore, as shown in FIG. 5B, the left eye line data LD1 is displayed from the pixel A to the pixel B of the display line L1 of the normal display 120A, and then the right from the pixel C to the pixel D of the display line R2 Eye line data RD1 is displayed. Finally, the left eye line data LD540 is displayed from the pixel M to the pixel N of the display line L1079, and the right eye line data RD540 is displayed from the pixel O to the pixel P of the display line R1080.

  Accordingly, the user who normally observes the display 120A can view the left eye image based on the left eye line data displayed on the odd-numbered display line 126a through the polarized glasses having different polarization characteristics on the left and right with the left eye and the even-numbered display line. The right eye image based on the right eye line data displayed on 126b can be viewed with the right eye, and the object can be perceived at a different image formation position from the display surface 124 through the stereoscopic image based on the binocular parallax.

  On the other hand, as shown in FIG. 6B, when the user visually recognizes the reverse display 120B, the uppermost part of the reverse display 120B becomes the display line 126b (R1080) and the lowermost part becomes the display line 126a (L1). The reversing display 120B of this embodiment has a function of automatically reversing and displaying the stereoscopic display data 202 by reversing the display order of the pixels constituting the display line 126 from the normal display order. . Therefore, as shown in FIG. 6A, when the video output unit 158 outputs line data to the reverse display 120B according to the arrangement order of the line data in the stereoscopic display data 202 as in the case of the normal display 120A, The left eye line data LD is displayed on the display line 126b for the right eye, and the right eye line data RD is displayed on the display line 126a for the left eye. In such a display state, when the user views the reverse display 120B, it becomes impossible to perceive an effective stereoscopic image.

  In view of this, the video output unit 158 of the present embodiment, as shown in “inverted display” in FIG. 6A, displays the stereoscopic display data 202 via the flip-flop circuits 160 of the same number as the number of pixels constituting one line. That is, the stereoscopic display data 202 delayed by one line is sequentially output to the reverse display 120B. Then, as shown in FIG. 6 (b), the stereoscopic display data 202 delayed by one input line is sequentially displayed on the reverse display 120B, and the left eye line data LD becomes the display line 126a for the left eye. The right eye line data RD is displayed on the right eye display line 126b. At this time, arbitrary data (for example, 0) set by the data delay unit 156 is displayed on the display line 126b (R1080) shown in FIG. 6B.

  As described above, the data delay unit 156 simply performs a simple process such as delaying the stereoscopic display data 202 to be displayed on the reverse display 120B by an odd number of lines, and the left eye video data is set to the left eye line and the right eye video data is set to the right side. It is possible to display on the eye line, and it is possible to realize effective stereoscopic display in the reverse display 120B as well as the normal display 120A.

  In addition, unlike the above, when the stereoscopic display data 202 is delayed for display on an inverted display that does not have the function of inversion display, for example, an inverted display that displays the stereoscopic display data 202 in the display order indicated by arrows in FIG. When the stereoscopic display data 202 is delayed for display on 130, the data delay unit 156 first holds the stereoscopic display data 202 in a memory (not shown). Then, the data delay unit 156 reads the stereoscopic display data 202 in the reverse order from the memory, that is, in the order of RD 540 to LD1, and further passes through the flip-flop circuit 160, so that the stereoscopic display data 202 after the rearrangement in the reverse order is 1 Can be delayed by line. As a result, an effective stereoscopic display can be realized on the reverse display 130 as well as the normal display 120A. At this time, arbitrary data (for example, 0) set by the data delay unit 156 is displayed on the display line 126a (L1) shown in FIG.

  In the above-described embodiment, an example is given in which the data delay unit 156 displays the stereoscopic display data 202 with a delay of one line from the original display timing. However, the stereoscopic display data 202 is relative to the display timing of the reverse display 120B. The object can be achieved by advancing (earning) the display timing of the reverse display 120B.

  That is, as shown in FIG. 8, the data processing unit 152 outputs the stereoscopic display data 202 to the reverse display 120B at the original display timing like the normal display 120A, and the data delay unit 156 directly connected to the data acquisition unit 150. However, the synchronization signal is advanced by one line, and the synchronization signal advanced by one line is output only to the inverted display 120B. In the reverse display 120B, the display is started earlier by one line according to the synchronization signal advanced by one line, and the stereoscopic display data 202 input from the data processing unit 152 is started to be displayed at the display timing of the second line. Thus, the stereoscopic display data 202 is displayed from the second line as in the above-described embodiment, and it is possible to realize effective stereoscopic display on the reverse display 130 as well as the normal display 120A.

  As described above, the stereoscopic video display device 100 according to the present embodiment performs simple processing such as delaying the stereoscopic display data 202 by an odd number of lines even when the processing capability of the stereoscopic video display device 100 is low. The correspondence relationship between the stereoscopic display data 202 and the display line 126 can be made to match. With such a configuration in which the video output unit 158 displays the delayed stereoscopic display data 202 on the reverse display 120B, effective stereoscopic display can be realized in the same manner as the normal display 120A.

  By the way, as shown in FIG. 1, the stereoscopic image display apparatus 100 is juxtaposed with the reverse display 120B on the upper part of the normal display 120A. Therefore, when the 3D image data or the 3D display data acquired by the data acquisition unit 150 is accompanied by sound, the speakers 140a and 140b of the inverted display 120B are turned upside down. 140b and 140c, and the right sound is output from the speakers 140a and 140d.

  Therefore, the stereoscopic video display apparatus 100 according to the present embodiment is such that the left audio is output from the speakers 140a and 140c and the right audio is output from the speakers 140b and 140d, so that the audio is output from the wrong direction. It is possible to prevent confusion of sound images. In addition, when the stereoscopic image display apparatus 100 includes four displays 120 and two normal displays 120A are arranged below and two inverted displays 120B are juxtaposed on top of the normal displays 120A, the left side of the speakers 140 disposed at both ends is respectively left. Sound and right sound are output, and sound is not output from the other speakers, so that mixing of sound images due to output of sound from the wrong direction can be prevented.

(3D image display method)
Next, a stereoscopic video display method for displaying stereoscopic video by binocular parallax using the stereoscopic video display device 100 described above will be specifically described.

  FIG. 9 is a flowchart showing the overall flow of the stereoscopic image display method. As shown in FIG. 9, the data acquisition unit 150 acquires stereoscopic display data and a synchronization signal (S200), and the data processing unit 152 performs image processing such as RGB processing on the stereoscopic display data (S202).

  Then, the line detection unit 154 detects the arrival timing of the first line of the stereoscopic display data, and inputs the detection result to the data delay unit 156 (S204). The data delay unit 156 sets the outputs of all the flip-flop circuits 160 to arbitrary data (for example, 0) based on the detection result input in the timing input step S204 (S206), and thereafter all the flip-flop circuits 160. The stereoscopic display data input to is delayed by one line (S208).

  When outputting the stereoscopic display data 202 to the normal display 120A (YES in S210), the video output unit 158 sequentially outputs the line data according to the arrangement order of the line data in the stereoscopic display data subjected to the image processing in the image processing step S202 ( S212).

  On the other hand, when outputting the stereoscopic display data 202 to the reverse display 120B (NO in S210), the video output unit 158 outputs the line data according to the arrangement order of the line data in the stereoscopic display data delayed by one line in the data delay step S208. The data are sequentially output (S214).

  As described above, also in the stereoscopic image display method according to the present embodiment, the stereoscopic display data can be displayed on the reverse display 120B by performing simple processing such as delaying the stereoscopic display data by an odd number of lines. As in the case of displaying on the normal display 120A, it is possible to realize effective stereoscopic display.

(Second embodiment: information processing apparatus 300)
In the above-described first embodiment, the stereoscopic image display apparatus 100 that can realize effective stereoscopic display even when the stereoscopic display data is displayed by being delayed by an odd number of lines to be displayed on the reverse display 120B has been described. In the present embodiment, by processing the stereoscopic display data itself in advance, it is possible to realize effective stereoscopic display as in the case of displaying on the normal display 120A even when the video is inverted and displayed on the inverted display 120B. The information processing apparatus 300 will be described. In addition, about the component substantially equivalent to 1st Embodiment mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 10 is a functional block diagram illustrating a schematic function of the information processing apparatus 300 according to the second embodiment. As shown in FIG. 10, the information processing apparatus 300 includes a video generation unit 310, a left-eye video holding unit 312a and a right-eye video holding unit 312b as video holding units, a line sequential unit 314, and a display 120 (normal display). 120A and reversal display 120B).

  The video generation unit 310 generates stereoscopic video data in response to an operation input by a user to an operation unit (not shown) or the like. Here, the stereoscopic video data is, for example, video data captured by the user personally. The video generation unit 310 performs arithmetic processing on the generated stereoscopic video data to generate left-eye video data and right-eye video data for realizing stereoscopic viewing by binocular parallax, and the left-eye video data is converted to the left-eye video data. The holding unit 312a causes the right eye video data to be held in the right eye video holding unit 312b. In addition, the video generation unit 310 acquires stereoscopic video data broadcast from the external broadcasting station 104 via the antenna 106, or via a recording medium 108 such as a DVD or a BD, or a communication network (Internet or LAN) 110. 3D video data can be acquired from the external server 112. In addition, the video generation unit 310 directly outputs a synchronization signal, which is a signal that can specify the left-eye video, the right-eye video, the display start position, and the like of the stereoscopic video data to the normal display 120A and the reverse display 120B.

  The left eye video holding unit 312a holds the left eye video data generated by the video generation unit 310, and the right eye video holding unit 312b holds the right eye video data independently.

  Since the line sequential unit 314 is normally displayed on the display 120A, each horizontal line is set so that the left-eye video data and the right-eye video data in the stereoscopic video data correspond to the first display line and the second display line, respectively. Are alternately juxtaposed and the first stereoscopic display data 202a is output to the normal display 120A. Further, since the line sequential unit 314 is displayed on the reverse display 120B, the left eye video data and the right eye video data in the stereoscopic video data 200 correspond to the second display line and the first display line, respectively. The horizontal lines are alternately juxtaposed to output the second stereoscopic display data 202b to the reverse display 120B.

  11 and 12 are explanatory diagrams for explaining the line sequential unit 314. FIG. As shown in FIG. 11A, the line sequential unit 314 includes a line count unit 320, a first switch 322, a line number determination unit 324, a replacement unit 326, and a second switch 328. .

  The line count unit 320 sequentially counts the target line name for specifying the target of the stereoscopic display data to be output from LD1 to RD1080 in a predetermined order (for example, the order shown in FIG. 11B), The count result is output to the first switch 322, the line number determination unit 324, and the replacement unit 326.

  The first switch 322 includes either an input terminal connected to the line count unit 320 or an input terminal connected to a replacement unit 326 described later according to a control signal of the line number determination unit 324 described later, and a second switch The output terminal connected to 328 is connected.

  The line number determination unit 324 switches the connection point between the input terminal and the output terminal of the first switch 322 based on the target line name counted by the line count unit 320. Here, when the target line name is from LD1 to RD540, that is, when generating the stereoscopic display data 202b shown in FIG. 12, the line number determination unit 324 connects the input to the replacement unit 326 side, and the target line name is from LD541 to RD1080. In the case of generating the stereoscopic display data 202a, the line count unit 320 is directly connected.

  The replacement unit 326 replaces L and R of the target line name counted by the line count unit 320 and outputs the result to the first switch 322. For example, when the target line name counted by the line count unit 320 is LDn, the replacement unit 326 replaces LDn with RDn, and outputs the replaced RDn to the first switch 322. Similarly, when the target line name counted by the line count unit 320 is RDn, RDn is replaced with LDn, and the replaced LDn is output to the first switch 322.

  Based on the target line name output from the first switch 322, the second switch 328 reads the video data held by the left eye video holding unit 312a or the right eye video holding unit 312b in units of lines and sequentially outputs them to the display 120. .

  Accordingly, as shown in FIG. 12, when the line sequential unit 314 outputs the stereoscopic display data 202a to the normal display 120A, the left eye line data and the right eye line data in the order of the target line names counted by the line count unit 320. And the stereoscopic display data 202a in which the and are alternately juxtaposed are output.

  Also, as shown in FIG. 12, when the line sequential unit 314 outputs the stereoscopic display data 202b to the reverse display 120B, the replacement unit 326 converts the L and R of the target line name counted by the line count unit 320 to the replacement unit 326. In other words, adjacent line data (left eye line data LD and right eye line data RD), for example, left eye line data LD1 and right eye line data RD1 are replaced, and left eye line data LD540 and right eye are replaced. The stereoscopic display data 202b in which the line data RD540 is replaced is output.

  As described above, like the information processing apparatus 300, when the processing capability is high and processing such as data rearrangement does not become a burden, the information processing apparatus 300 does not impair the data, and the stereoscopic display corresponding to the reverse display 120B is possible. The display data 202b can be reliably output. Therefore, the information processing apparatus 300 generates data for the reverse display 120B by rearranging data in advance before displaying on the display 120, so that the reverse display 120B is also a normal display without any processing on the display 120 side. As in the case of 120A, an effective stereoscopic display can be realized.

(3D image display method)
Next, a stereoscopic image display method for outputting the stereoscopic display data 202a to be displayed on the normal display 120A and the stereoscopic display data 202b to be displayed on the reverse display 120B using the information processing apparatus 300 described above will be specifically described.

  FIG. 13 is a flowchart showing the overall flow of the stereoscopic image display method. As shown in FIG. 13, the video generation unit 310 generates stereoscopic video data (S400). Then, the left eye video holding unit 312a holds the left eye video data, and the right eye video holding unit 312b holds the right eye video data individually (S402).

  On the other hand, the line counting unit 320 of the line sequential unit 314 sequentially counts the target line name of the stereoscopic display data to be output from LD1 to RD1080, and the count result is sent to the first switch 322, the line number determination unit 324, and the replacement unit 326. Output (S404). The replacement unit 326 replaces L and R of the target line name counted by the line count unit 320 and outputs them to the first switch 322 (S406).

  The line number determination unit 324 determines whether the counted target line name is from LD1 to RD540 (S408). If the counted target line name is from LD1 to RD540 (YES in S408), the line number is determined. The number determination unit 324 connects the input of the first switch 322 to the replacement unit 326 side (S410). Then, the first switch 322 outputs the target line name in which L and R of the target line names counted by the line count unit 320 are replaced by the replacement unit 326 to the second switch 328 (S412). Then, the second switch 328 reads out the left-eye video data or the right-eye video data held in the data holding step S402 on a line basis based on the replaced target line name, and sequentially outputs them to the reverse display 120B (S414).

  On the other hand, if the counted target line name is not LD1 to RD540, that is, LD541 to RD1080 (NO in S408), the line number determination unit 324 directly connects the input of the first switch 322 to the line count unit 320 ( S416). Then, the first switch 322 outputs the target line name counted by the line count unit 320 to the second switch 328 (S418). Then, the second switch 328 reads the left-eye video data or right-eye video data held in the data holding step S402 on a line basis based on the target line name counted by the line counting unit 320, and sequentially outputs the data (S414). .

  Then, it is determined whether or not all target line names have been output, that is, whether or not RD1080 has been output (S420). If not completed (NO in S420), the process returns to the line count step S404 to perform data output processing. repeat.

  As described above, in the stereoscopic video display method according to the present embodiment, the reversing display 120B can realize effective stereoscopic display similarly to the normal display 120A without performing any processing on the display 120 side. Become.

  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. Is done.

  For example, in the above-described embodiment, the display has been described using a display in which display lines are juxtaposed in the horizontal direction, but the effect of the present invention can be obtained even by using a display in which display lines are juxtaposed in the vertical direction. be able to. Moreover, although one display line in the display has been described as one pixel line, any number of pixel lines may be used as one display line.

  Note that each step of the stereoscopic image display method of the present specification does not necessarily have to be processed in time series in the order described in the flowchart, and may include processing in parallel or by a subroutine.
