Three-dimensional video display device, control method thereof, and screen adjusting program

A control method of a three-dimensional video display that disposes a mirror device in which a plurality of mirrors are disposed to be parallel to each other in a video display device which includes a display unit having a display screen that displays a screen with a predetermined format having a plurality of regions corresponding to the plurality of mirrors in order to display a three-dimensional video and an input unit that is manipulated by a user, and reflects a video displayed on a display screen of the video display device from the plurality of mirrors to display the video as a three-dimensional video, the method comprising:

• a step for generating an adjusting screen with the format including display of a specific indication mark which is used to check display irregularity of the screen in a relationship between the mirror and the region of the screen with the format;
• a shift input step for instructing the screen with the format which is displayed on the display screen to be moved in a forward or backward direction of the display screen as seen from the user by the manipulation of the input unit;
• a screen shift control step for controlling the adjusting screen including the indication mark to be moved forward or backward by a predetermined amount to be displayed on the display screen in accordance with an instruction from the shift input step;
• a step for generating the screen with the format in a state where the screen is moved by a predetermined amount by the screen shift control step by disposing a video for displaying the three-dimensional video in the plurality of regions;
• and
• a step for displaying the video of the screen with the format generated by the generating step on the display screen of the video display device and reflecting the displayed video from the plurality of mirrors to be displayed as a three-dimensional video.

A computer readable medium storing a screen adjusting program that is executed by a processor in a three-dimensional video display device that disposes a mirror device in which a plurality of mirrors are disposed to be parallel to each other in a video display device which includes a storage unit that stores a program and a video, a processor that executes the program, a display unit having a display screen that displays a screen with a predetermined format having a plurality of regions corresponding to the plurality of mirrors in order to display a three-dimensional video and an input unit that is manipulated by a user, and reflects a video displayed on a display screen of the video display device from the plurality of mirrors to display the video as a three-dimensional video, the program executes operations comprising:

• a step for generating an adjusting screen with the format including display of a specific indication mark which is used to check display irregularity of the screen in a relationship between the mirror and the region of the screen with the format;
• a shift input step for instructing the screen with the format which is displayed on the display screen to be moved in a forward or backward direction of the display screen as seen from the user by the manipulation of the input unit;
• a screen shift control step for controlling the adjusting screen including the indication mark to be moved forward or backward by a predetermined amount to be displayed on the display screen in accordance with an instruction from the shift input step;
• and
• a step for generating the screen with the format in a state where the screen is moved by a predetermined amount by the screen shift control step by disposing a video for displaying the three-dimensional video in the plurality of regions.
