Description

  The present invention relates to a 3D video display device, a control method thereof, and a screen adjustment program, and in particular, a video in a 3D video display device that displays a video displayed on the video display device as a 3D video using a mirror. This is related to the screen adjustment of display deviation.

  A three-dimensional video display device that displays a video displayed on a two-dimensional video display device as a three-dimensional video using a mirror assembly including a plurality of half mirrors is known. For example, Patent Document 1 discloses a three-dimensional video display device proposed by the present invention. That is, two-dimensional image display is performed using a mirror device having a plurality of mirrors (half mirrors and full mirrors) inclined at a predetermined angle on the screen of the two-dimensional image display device at a predetermined angle in the depth direction. On the screen of the device, a plurality of virtual image generation regions that generate virtual images by mirrors corresponding to the position of the mirror and a virtual image generation region that does not generate virtual images interposed between the virtual image generation regions are formed. The image displayed on the screen is reflected by the corresponding mirror and displayed as a three-dimensional image on the viewer side.

  Patent Document 2 also discloses a similar three-dimensional display device. In Patent Document 2, in particular, when displaying information in each of the display areas divided into (N + 1) pieces of the display screen, the display size (size of the display area) for displaying information by the enlargement / reduction control unit 105 is shown. It is described that the enlargement / reduction control is performed.

  In this 3D image display device, a desired 3D image cannot be displayed unless the virtual image generation area on the screen of the 2D image display device appropriately corresponds to the position of the mirror. That is, if the virtual image generation area does not correctly correspond to the position of the mirror, the video may be shifted up and down from a predetermined position, or the video of the virtual image generation area other than the virtual image generation area may be displayed.

  The video displayed on the 3D video display device is produced according to the screen of the 3D video format 90 as shown in FIG. In the 3D video format 90, a plurality of virtual image generation areas 91 and a plurality of virtual image non-generation areas 92 are alternately formed, and videos 94a to 94c are generated in the virtual image generation area 91. The images 94a to 94c generated in the virtual image generation area 91 of the 3D image format 90 are reflected by a plurality of mirrors and displayed as a desired 3D image.

  However, there are cases where the positional relationship between the mirror and the screen of the 2D video display device is not appropriate due to various causes. For example, when a mirror device is attached to a smartphone as a two-dimensional video display device with a case called a jacket, the positional relationship is shifted by the thickness of the jacket. In such a case, the virtual image generation area 91 on which the video is displayed is shifted in the front-rear direction from the normal position, so that the three-dimensional video is displayed with a shift from the normal position.

  In addition, since the size of the screen of the smartphone varies depending on the model, the mirror position of the mirror device and the virtual image generation region may not match even in the video produced according to the 3D video format 90. In such a case, it is necessary to enlarge and reduce the image so that the intervals Eb and Ec between the virtual image generation regions coincide with the mirror intervals Db and Dc.

  Since there are many types of jackets and 2D video display devices, it is practically difficult to automatically adjust the screen including the virtual image generation region corresponding to all of them. For example, a method of holding the size information of the screen in a memory or the like of a 2D video display device and automatically reading the size information when displaying the 3D video and adjusting the screen according to the size information can be considered. However, whether or not the jacket is attached to the 2D video display device, and the thickness of the jacket, etc., are state information different from the 2D video display device. It is difficult to hold it in the two-dimensional video display device. For this reason, it is preferable that the viewer adjusts the screen at the time of displaying the 3D video manually while watching the 3D video.

  Patent Document 2 describes that the enlargement / reduction control unit 105 controls the enlargement / reduction of the display size for displaying information, but how to adjust the display shift in the depth direction of the screen. There is no suggestion of control. Further, there is no suggestion that the viewer adjusts the display deviation by the viewer's own operation while watching the screen.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an example of a three-dimensional video display device in one embodiment.
The three-dimensional video display device includes a two-dimensional video display device 70 and a mirror device 80. The two-dimensional video display device 70 is a video display device such as a smartphone or a tablet terminal. The mirror device 80 is inclined at a predetermined angle toward the viewer K with respect to the screen 71 (meaning a physical screen), and is provided with a plurality of mirrors (half mirrors 81 and 82) arranged in parallel in the depth direction at predetermined intervals. Full mirror 83) is provided. The viewer uses the mirror device 80 by attaching it to the two-dimensional image display device 70. On the screen 71 of the two-dimensional video display device 70, a plurality of virtual image generation regions and a virtual image non-generation region that does not generate a virtual image interposed between the virtual image generation regions are formed and displayed on the virtual image generation regions 91a to 91c. The image is reflected by the corresponding mirrors 81 to 83 and displayed on the viewer side as a three-dimensional image.

  FIG. 1 schematically shows a three-dimensional video display device. FIGS. 14 and 15 show a configuration of the mirror device 80 and an example of mounting of the mirror device 80 and the two-dimensional video display device 70. Referring to these drawings, the mirror device 80 mainly includes a mirror case 8a in which rectangular half mirrors 81 and 82 and a full mirror 83 (hereinafter simply referred to as mirrors) are mounted in parallel, and a two-dimensional image display device 70. It is comprised from the main body case 8b which mounts. The mirror case 8a and the main body case 8b are connected by a hinge portion 8f. Therefore, the mirror case 8a, the main body case 8b, and the hinge portion 8f are preferably made by integral molding using a synthetic resin having high hinge resistance such as polypropylene. Three pairs of grooves are formed in parallel in the mirror case 8a, and rectangular mirrors 81 to 83 are fixed to the grooves. In this example, the main body case 8b has a shape that covers and holds the tip of the two-dimensional image display device 70, and the width and depth length of the two-dimensional image display device 70 with the jacket and the length and width are slightly different. It has a size and shape that allows a two-dimensional video display device to be inserted and mounted.

  As shown in FIG. 14, with the mirror case 8a opened, the two-dimensional image display device 70 is inserted into the main body case 8a from the front (viewer side), and its tip is pressed against the innermost part of the main body case 8a. It is done. When the mirror case 8a is closed in this state, a state as shown in FIG. 15 is obtained, and the viewer views a virtual image obtained by reflecting the image formed on the screen 71 of the two-dimensional image display device 70 on the mirrors 81 to 83. Can be appreciated.

Next, the display deviation adjustment function of the screen will be described.
In this embodiment, a screen shift adjustment function and an enlargement / reduction function are set in order to adjust the display deviation of the screen. In order to check whether or not there is a display deviation on the screen, and to realize a shift adjustment function and an enlargement / reduction adjustment function, a display deviation adjustment screen (hereinafter simply referred to as an adjustment screen) 6 is defined. The adjustment screen 6 is a screen defined as a predetermined format.

  The adjustment screen 6 will be described later with reference to FIGS. 6, 11, and 13. Generally speaking, the adjustment screen is stored in the storage unit 204 or the memory 203, and the three-dimensional video format is associated with the execution of the screen adjustment program. 90 is displayed on the screen 71 of the two-dimensional video display device. In the adjustment screen 6, reference marks 61a, 61b, 61c (see FIG. 6), a shift adjustment function (mode), or an enlargement / reduction function (mode) are set as a display for confirming whether or not there is a screen shift. Mode button 51, shift button 52 (see FIG. 11) for shifting (moving) the screen by a certain amount in the front (viewer) direction or back direction (direction away from the viewer), and expanding the screen size Alternatively, an enlargement / reduction button 53 (see FIG. 13) and an end button 54 for reduction control are set. The shift button 52 includes a front shift button 52a that shifts the screen forward by a fixed amount and a back shift button 52b that shifts the screen by a fixed amount. The enlargement / reduction button 53 includes a reduction button 53a and an enlargement button 53b.

  In the case of a smartphone or tablet terminal, the input unit 206 is set as a plurality of touch (contact) display buttons (also referred to as display keys) on the screen 71, so the mode button 51, the shift button 52, the enlargement / reduction button 53, and the end The button 54 and the like are also set on the adjustment screen 6 as touch-type input keys. Further, the mode button 51, the shift button 52, the enlargement / reduction button 53, and the end button 54 are arranged in the virtual image generation area 91a in the adjustment screen 6 and closest to the viewer. Thus, the viewer can operate these buttons with a finger from the inside of the mirror case 8a in a state where the mirror device 80 is mounted on the two-dimensional image display device 70.

  The mode button 51 can be switched between a shift mode and an enlargement / reduction mode each time it is pressed. In the shift mode, the adjustment screen 6 including the shift button 52 is displayed as shown in FIG. 11 (a), and in the enlargement / reduction mode, the adjustment screen 6 including the enlargement / reduction button 53 is displayed as shown in FIG. 13 (a). Is done. When the end button 54 is pressed, the screen adjustment control operation ends.

  5A is a side view of the 3D video display device, that is, the mirror device 80 and the 2D video display device 70, and FIG. 5B is a video 94 displayed on the 2D video display device 70 in the 3D video format 90. FIG. FIG. 6 is a plan view on which an adjustment screen 6 is displayed.

  In the example shown in FIG. 5, the intervals between the boundary lines 93 of the 3D video format 90 are Eb and Ec, and the intervals between the lower ends 81a, 82a and 83a of the mirrors 81, 82 and 83 are Db and Dc. And Eb = Db, Ec = Dc. Further, it is important that the boundary lines 93a, 93b, and 93c are at the same position as the lower ends 81a, 82a, and 83a of the mirror. In such a state, virtual images 94a ', 94b', 94c 'of the images 94a, 94b, 94c displayed on the screen 71 of the two-dimensional image display device 70 are generated at desired positions, and desired three-dimensional An image is displayed. Here, the boundary line refers to a line that divides the screen of the 2D video in order to project the 2D video displayed on the screen onto a plurality of mirrors. A boundary line 93 represents the position of a straight line existing in the 3D video format 90.

  The screen adjustment is preferably performed by combining the shift adjustment function and the enlargement / reduction adjustment function. Therefore, when the enlargement / reduction operation is performed, the adjustment screen 6 is enlarged / reduced based on the reference point 63b (FIG. 13). The reference point 63b is on the boundary line 93b of the adjustment screen 6. By having the reference point 63b at this position, the boundary line 93b is always constant without moving in the front-rear direction regardless of any enlargement / reduction.

  In the screen adjustment operation by the viewer, first, the boundary line 93b is aligned with the lower end 82a of the mirror 82 by shift adjustment. FIG. 12 shows an image viewed by the viewer at this time. At this stage, the viewer operates the shift button so that the virtual image 62b 'of the reference point of the reference mark 61b comes on the mirror lower end 82a. No attention is paid to the positions of the virtual images 62a 'and 62c' of the other reference marks 61a and 61c. Next, the viewer operates the mode button 51 to switch to the enlargement / reduction mode. Then, the enlargement / reduction button is operated until the virtual images 62a 'and 62c' of the reference marks 61a and 61c are positioned at the mirror lower ends 81a and 83a, respectively, as shown in FIG. Since the boundary line 93b and the lower end of the mirror 82a are fixedly set, the state shown in FIG. 8 can be achieved with a small number of operations of the enlargement / reduction button.

  In this way, the boundary line 93b and the mirror lower end 82a are first matched by shift adjustment, and then the enlargement / reduction adjustment is performed while the boundary line 93b is fixed, and the other boundary lines 93a and 93c are adjusted to the mirror lower ends 81a and 83a. By following the procedure for adjusting to, appropriate shift adjustment and enlargement adjustment can be surely performed with simple operations.

  Note that the position of the reference point can be set to other than 63b. For example, it may be at a position 63a on the boundary line 93a. In this case, the boundary line 93a is first aligned with the mirror lower end 81a by shift adjustment, and the subsequent operation is the same as described above.

With reference to FIG. 6, an example of the display deviation adjustment screen and the reference mark 61 on the screen will be described.
The adjustment screen 6 is preferably a single still image having the same resolution as the physical resolution of the screen 71 of the 2D video display device 70. This adjustment screen is normally stored in the storage unit 204 or the memory 203, and as will be described later, as the screen adjustment program is executed by the processor 202, the screen 71 of the 2D video display device is converted into a 3D video format 90. Is displayed.

  On the adjustment screen 6, reference marks 61a, 61b, 61c made of a pair of triangular figures are drawn on the boundary line 93 of the three-dimensional video format 90 so that the vertices are in contact with the line. The fiducial marks touch each other at a single vertex 62. Since the reference marks 61 are drawn near the boundary, when the boundary line 93 is three, a total of six reference marks 61 are drawn at the respective positions.

  In a preferred example, the reference mark 61 is a pair of triangles as shown in FIG. However, according to the alternative example, the present invention is not limited to this, and for example, arrows facing each other as shown in (b) and (c) may be used. Furthermore, as shown in (d), it may be a circular arc facing each other. In short, a figure in which a pair of figures having vertices are in contact with each other at the boundary line 93 and is drawn symmetrically on both sides of the boundary line 93 is preferable. Further, as shown in (e), the apex may not be in contact with the boundary line 93 and may be slightly separated.

Furthermore, it is not a line-symmetrical figure with respect to the boundary line 93 as in the above example, but may be a figure that is slightly shifted laterally as shown in (f).
Furthermore, instead of a figure or a symbol, a combination of one or a plurality of simple characters (for example, “48”) and a figure (triangle) may be used as in (g). The character and the vertex of the triangle are in contact with each other at the boundary line 93. If the screen display is shifted in any direction, the viewer may see that the characters are cut off or the triangles are visible, and thus it is understood that the screen shift adjustment is necessary.
In short, any display mark such as a figure, a symbol, or a character can be used as long as the difference between the image displayed on the screen 71 and the image reflected on the mirrors 81 to 83 is easily understood.

[When there is no screen shift]
FIG. 8 is a perspective view of a three-dimensional image of an adjustment screen that does not require screen adjustment.
FIG. 8 is a perspective view seen from the viewer's viewpoint when the adjustment screen 6 is displayed on the 3D video display device. In this state, the lower ends 81a, 82a, and 83a of the mirror are aligned with the boundary lines 93a, 93b, and 93c of the adjustment screen 6 in FIG. 5 or FIG. In this case, the intervals Eb, Ec of the boundary lines 93a, 93b, 93c and the intervals Db, Dc of the mirror lower ends 81a, 82a, 83a are equal distances. FIG. 11A shows the positional relationship between the screen 71 of the two-dimensional video apparatus 70 and the adjustment screen 6 in that state. In this case, as shown in FIG. 8, the virtual images 62a ′, 62b ′, 62c ′ of the apex 62 of the triangular reference mark 61 are displayed in contact with the mirror lower ends 81a, 82a, 83a, respectively.

[If there is a screen shift]
As shown in FIG. 11 (b), the two-dimensional image display device 70 is shifted to the front (front side as viewed from the viewer) from the mirror device 80, and the mirror lower ends 81a, 82a, 83a and the boundary lines 93a, 93b, 93c. In the state in which they do not match, the virtual images 62a ′, 62b ′, 62c ′ of the vertexes of the reference marks are displayed in a state separated from the mirror lower ends 81a, 82a, 83a, respectively, as shown in FIG.

  Further, as shown in FIG. 11 (c), the two-dimensional image display device 70 is shifted to the back (back side as viewed from the viewer) from the mirror device 80, and the mirror lower ends 81a, 82a, 83a and the boundary lines 93a, 93b. , 93c are not coincident with each other, as shown in FIG. 10, the virtual images of the apexes of the reference marks are displayed in a state where they are not seen under the mirror lower ends 81a, 82a, 83a.

  In contrast to the states shown in FIGS. 9 and 10, it is obvious that in the example of FIG. 8, the virtual images 62a ′, 62b ′, and 62c ′ of the vertexes of the reference marks are in contact with the mirror lower ends 81a, 82a, and 83a, respectively. I understand. That is, by displaying the adjustment screen 6, the viewer can display whether the screen 71 of the two-dimensional video display device 70 is in a desired position with respect to the mirror device 80 in a clear and easy-to-understand manner.

  As shown in FIGS. 9 and 10, when the screen 71 is displaced and the positions of the two-dimensional image display device and the mirror device 80 cannot be physically adjusted, the desired three-dimensional image can be obtained by adjusting the screen shift. Can be displayed.

[Shift adjustment]
The screen shift adjustment function will be described with reference to FIG.
In order to adjust the shift of the image, a touch-type shift button 52 is provided on the adjustment screen. The shift button 52 includes a front shift button 52a and a back shift button 52b. Each time the front shift button 52a is pressed once, the display of the adjustment screen moves forward by a certain amount of distance (one pixel). Each time the backshift button 52b is pressed once, the display of the adjustment screen moves to the back by a certain amount of distance.
Here, as shown in FIGS. 1 and 11, the shift button 52 is used by the viewer in the virtual image generation area 91 a so that the viewer's finger can touch even when the mirror device 80 is mounted on the two-dimensional video display device. It is preferable to arrange on a screen close to the side.

If the button is located in a place other than the virtual image generation area 91a, the mirror device 80 is moved away from the screen 71, the button is pressed, and the mirror device is attached to the screen 71 to check the stereoscopic image. It will take time to adjust.
Note that the screen shift control itself can be easily realized using a known screen movement control technique.

9 and 10, when the viewer presses the front shift button 52a or the back shift button 52b a desired number of times while viewing the 3D image while the mirror device 80 is mounted on the 2D image display device, The screen display moves by a predetermined amount according to the operation. Finally, the display on the screen can be adjusted and set to the position of the regular reference mark as shown in FIG.
In this way, the viewer can perform the shift adjustment operation of the screen while viewing the three-dimensional images as shown in FIGS. 8 to 10, so that the adjustment operation is intuitive and easy to understand. Further, there is an advantage that the shift of the screen can be adjusted by operating the shift button 52 with the mirror device 80 mounted.

[When the screen size is different]
As shown in FIGS. 13B and 13C, when the sizes of the screen 71 and the adjustment screen 6 are different, the virtual image 62c ′ of the apex of the reference mark 61c is separated from the mirror lower end 83a as shown in FIG. The virtual image 62a 'at the apex of 61a disappears because the virtual image at the apex of the reference mark below the lower end 81a of the mirror sinks. As described above, when the sizes of the screen 71 and the adjustment screen 6 are different, the viewer can intuitively understand that the desired three-dimensional image cannot be obtained. In such a case, a desired 3D image can be obtained by adjusting and displaying the image.

  In order to adjust the enlargement / reduction of the video, as shown in FIG. 13, a touch-type enlargement / reduction button 53, that is, a reduction button 53a and an enlargement button 53b are provided on the adjustment screen. Each time the reduction button 53a is pressed, the display of the adjustment screen is reduced and displayed by a certain amount.

The two-dimensional video display device 70 is a mobile terminal such as a smartphone, a communication unit 201 that transmits and receives data to and from a service providing device such as the Web server 28 through the communication network 29, a processor (CPU) 202 that executes a program, and a program And a memory 203 such as a semiconductor memory that stores data being processed, a large-capacity storage unit 204 that stores content data such as programs and videos, a display unit 205 that displays video and various information, and an input operated by a user The unit 206 is configured.

  The processor 202 executes various application programs (hereinafter simply referred to as programs). In particular, in this embodiment, when displaying a 3D video, a video display program for displaying the 2D video on the screen of the video display device according to a special format for 3D video (3D video format) is executed. The three-dimensional video format is a format for drawing video in a plurality of divided virtual image generation areas.

  In addition, a program (hereinafter referred to as a screen adjustment program) for realizing a display deviation adjustment function characteristic of the present embodiment is executed. These video display programs and screen adjustment programs are downloaded via the network 29 and the communication unit 201 from the Web server 28 of the provider that provides a 3D video display service by the viewer operating the input unit 206 of the video display device. And get it. These acquired programs are stored in the storage unit 204. These programs are loaded from the storage unit 204 to the memory 203 and executed by the processor 202. The 2D video (video content) to be displayed by executing the video display program includes a movie, a landscape, a game, and the like. These video content are also downloaded and acquired from the Web server 28 in the same manner. Stored in the storage unit 204.

Here, the processing operation by the screen adjustment program will be described later with reference to FIG. 3. This screen adjustment program starts to be executed by the video display program in the processor 202, and the video in the 3D video format desired by the viewer. This screen adjustment program is executed before the screen is displayed, and it can be controlled to adjust the screen shift.
As another example, while the video display program is being executed by the processor 202 and the video in the 3D video format is being displayed, the viewer notices a screen display shift and tries to adjust the screen. In this case, the screen adjustment program can be activated and executed by operating a specific button. In this case, the video display is temporarily interrupted.

  In a two-dimensional video display device such as a smartphone, the input unit 206 is provided with a plurality of touch-type display buttons, and each display button can have various input functions (functions). In the case of the present embodiment, a shift button for moving the screen in the front-rear direction and an enlargement / reduction button for changing the size of the screen to enlarge or reduce are set as the input function of the display button. If the 2D video display device is not a smartphone but a mobile terminal having an input unit 206 composed of a display screen and a plurality of mechanical keys, the above function keys can be realized by these mechanical keys. It is.

  Note that the screen adjustment program may not be a separate program independent of the video display program, but may be incorporated therein as one function of the video display program. In this case, each time the video display program is executed, the function of the screen adjustment program can be executed at the beginning or at an appropriate time.

[Screen deviation adjustment control operation]
Next, the screen adjustment control operation for screen shift will be described with reference to the flowchart of FIG.
This control operation is performed by the processor 202 executing a screen adjustment program stored in the storage unit 204 or the memory 203. By executing this screen adjustment program, it is possible to selectively set a shift mode for moving the screen in the front-rear direction and an enlargement / reduction mode for changing the screen size to be enlarged or reduced as the screen change control mode. it can. Further, the adjustment screen changed by the screen adjustment program is initially stored in the storage unit 204 or the memory 203.

  When the screen adjustment program is started, first, in the initialization operation, the control mode is set to the shift mode, the shift value is set to “0”, and the enlargement / reduction value is set to “0.0” (S301). Then, the adjustment screen stored in the storage unit 204 or the memory 203 is read out, and these initial values are set in the adjustment screen to generate the adjustment screen 6 (the adjustment screen as shown in FIG. 11A). (S302). The generated adjustment screen includes a front shift button 52a, a back shift button 52b, a mode button 51, and an end button 54. The adjustment screen is displayed on the screen 71 with the current shift value and enlargement / reduction value set. (S303). Here, the adjustment screen for the shift mode is set first in the initialization operation because the adjustment work for the viewer is better if the movement in the front-rear direction of the screen is adjusted first and then the enlargement / reduction is adjusted. It is because it is easy to do.

  In this state, when the mode button is pressed by the viewer (S305), the mode value is determined (S336). If the current mode value is the enlargement / reduction mode, the mode is changed from the shift mode to the enlargement / reduction mode (S3361). On the other hand, if the current mode value is the shift mode, the mode is changed from the shift mode to the enlargement / reduction mode (S3362). In short, this is an operation for switching the current mode to the other mode.

  In the determination of the mode button (S305), if the mode button is not pressed, it is determined what the current mode value is (S306). If it is determined that the current mode value is the shift mode, steps S307 to S309 are executed. On the other hand, if the current mode value is the enlargement / reduction mode, steps S327 to S329 are executed.

  In the shift mode, the front shift button 52a and the back shift button 52b are displayed on the adjustment screen (S307). Thereafter, when the front shift button 52a is pressed (S308), the shift value is increased (plus) by a predetermined amount each time, and an adjustment screen shifted forward (that is, in the direction approaching the viewer) according to the shift value is generated. Then, it is displayed on the screen 71 (S3082). On the other hand, when the backshift button 52b is pressed (S309), the shift value is decreased (minus) by a predetermined amount each time, and an adjustment screen shifted backward according to the shift value is generated and displayed on the screen 71. (S3092).

  Thereafter, when the end button 54 is pressed (S310), the screen adjustment program execution operation ends. On the other hand, when the end button 54 is not pressed, the process returns to S305. By this screen adjustment operation, the screen on which the video is displayed is adjusted in the front-rear direction for displaying the three-dimensional video (that is, the screen display shift is eliminated).

  In the shift mode, when neither the front shift button nor the back shift button is operated (S308 & S309, “No”), the displayed screen has already been adjusted in the front-rear direction (that is, the front-rear direction adjustment unnecessary state). . In this case, when the viewer presses the end button 54, the screen adjustment operation ends.

  When the mode button is pressed and the mode is changed to the enlargement / reduction mode (S306), processing S327 to S329 is executed. That is, in the case shown in FIG. 13B, when the enlargement button 53b is pressed (S328), the enlargement / reduction value is increased by a predetermined amount each time, and the adjustment screen 6 is generated according to the increased enlargement / reduction value. Then, it is displayed on the screen 71 (S3282). On the other hand, in the case as shown in FIG. 13C, when the reduction button is pressed (S329), the enlargement / reduction value is reduced by a predetermined amount each time, and the adjustment screen 6 is generated according to the reduced enlargement / reduction value. Is displayed on the screen 71 (S3292). Thereafter, when the end button 54 is pressed, the screen adjustment program execution operation ends (S310). When the end button is not pressed, the process returns to S305 and the above operation is repeated.

Here, the shift value and the enlargement / reduction value changed by the screen adjustment program are held in the memory 203 or the storage unit 204 even after the execution of the program is completed. Then, when displaying the video for displaying the three-dimensional video on the screen 71 of the display unit 205, the video is shift-controlled in the front-rear direction using the held shift value and enlargement / reduction value. The image is displayed on the screen 71 with enlargement or reduction control.
In this way, the screen displacement and size can be adjusted accurately and easily for 3D image display, and the 2D image is displayed on the screen 71 in a state in which the display displacement has been eliminated, and passed through the mirror device. A 3D image can be displayed.

As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to the said Example, It can implement in various deformation | transformation.
In the above embodiment, when the functions of the shift adjustment function and the enlargement / reduction adjustment function are provided as the screen adjustment of the display deviation, the function mode is switched by operating the mode button 51. However, the mode button 51 is changed to each function mode. It may be provided accordingly.

  In the above embodiment, the shift button 52 is provided with two buttons, a front shift button and a back shift button, and the enlargement / reduction button 53 is provided with two buttons, an enlargement button and a reduction button. Instead of providing two function buttons, one flick function button may be provided as a shift button, and one zoom function button by multi-finger touch may be provided as an enlargement / reduction button.

  Further, according to another alternative example, the front shift button 52a, the back shift button 52b, the enlarge button 53a, and the reduce button 53b may be displayed simultaneously. In this case, the mode button 51 need not be displayed.

  Further, although it is not directly related to the gist of the present invention, that is, screen misalignment adjustment, the mirror device is not limited to the one shown in FIGS. 14 to 15, and various designs are made according to the size and shape of the video display device.
