Abstract

PURPOSE:To extend the display angle of vision of a stereoscopic image by providing an image signal generation means, a selection means to select an arbitrary area of an image displayed with image signals, image signal extraction means, and a virtual image display means, selecting an arbitrary area of an image displayed with image signals then displaying it. CONSTITUTION:For example, the central position 230 of an area 200 is selected by the selection means 160, then an image position detection circuit 150 detects an area 210 that surround the central position 230, and supplies a detection signal to stereoscopic image selection circuits 140, 141. The circuits 140, 141 extract such image signals as indicated by the area 210 from among image signals 142, 143, and supply the signal respectively to cathode-ray tube display monitors 20, 10 respectively for right eye and left eye via respective image signal supplying circuits 130, 131. Consequently, the monitors 10, 20 for right eye and left eye display an image surrounded by the area 210. Therefore, differing from the conventional, the display area of a stereoscopic image is not limited, hence the display angle of vision can be extended.
