Patent attributes
A left parallax image and a right parallax image for a fundus of the same eye being examined are captured and recorded, and at least one of the two images is displayed. An image in a prescribed area is clipped from the displayed image, and an image in an area that corresponds to the area of the clipped image is clipped from the other image. The two clipped images are then enlarged and displayed on a stereo monitor in a left-right alignment. In such a configuration, when an area to be displayed at a high-magnification is specified for one of the images, clipping and high magnification processes may be performed also for the other image. This allows stereoscopic observations of an eye fundus at high magnification to readily be performed.
