Patent ID: 8675055

Claim:
A signal processing device comprising: a phase matching section adapted to bring two image signals supplied from two cameras arranged according to the distance between the left and right human eyes and adapted to image the same subject into phase, one image signal being a left image signal stored in a left image memory, the other image signal being a right image signal stored in a right image memory; a phase adjustment section adapted to change the horizontal phase of the left and/or right image signal based on a phase displacement specified by an operation section so as to move both or either of the left and right images displayed on a display section by the left and right image signals horizontally by a predetermined distance and output the left and right image signals with changed parallax between the left and right images; and a read section adapted to output the left and/or right image signal in which, of those areas displayed on the display section three-dimensionally due to the overlap of the left and right images with changed parallax and other areas where only the left or right image is displayed on the display section two-dimensionally, the image in the two-dimensionally displayed areas has been replaced by an image different from that in the three-dimensionally displayed areas, wherein the read section replaces, by other image signal, the area not including the left or right image signal on the screen of the display section due to leading or lagging phase of the left or right image signal to be supplied and outputs the resultant signal.
