Abstract:
1. An image display device comprising: a first image display unit that is provided not to reverse a display direction and displays an image by receiving a first display video signal and executing a scanning; a second image display unit that is provided to change a display direction to a first display direction and a second display direction which is a reversed direction to the first display direction and displays an image by receiving a second display video signal and performing a scanning; a video signal processing means that executes a predetermined signal processing for the video signal obtained based on a captured image; a scanning direction instructing means that instructs the second image display unit to execute a normal scanning in a first state corresponding to the first display direction and execute a reversed scanning by reversing a corresponding scanning direction to a movement direction of the second image display unit to reverse an image from the first display direction to the second display direction in a second state corresponding to the second display direction; a first color specifying means that specifies a color of a graphics image corresponding to the first image display unit; a second color specifying means that specifies a color of a graphics image corresponding to the second image display unit; a first position specifying means that specifies a position of the graphics image to be synthesized with an image of the video signal corresponding to the first image display unit; a second position specifying means that specifies a position of the graphics image to be synthesized with an image of the video signal corresponding to the second image display unit in such a way that a normal position is specified without horizontal reversing in the first state and a reversed position is specified by horizontally reversing in the second state; a first synthesizing means that outputs, as the first display video signal, a signal obtained by synthesizing a signal of a color stored when the first color specifying means specifies a color with the video signal input from the video signal processing means at a position specified by the first position specifying means; and a second synthesizing means that outputs, as the second display video signal, a signal obtained by synthesizing a signal of a color stored when the second color specifying means specifies a color with the video signal input from the video signal processing means at a position specified by the second position specifying means.
