Abstract
Method of efficiently inputting three-dimensional shape information, that is, distance data and depth data, which are prerequisite for presenting a panoramic image or a stereo image to a viewer. The first and second images obtained from an object are presented to a viewer as a stereo image, the left and right lines of sight of the viewer are detected at a predetermined timing, and three-dimensional coordinates of the point of interest where the viewer is gazing at are calculated based on the detected left and right line-of-sight data. The operation of detecting the line of sight and calculating three-dimensional coordinates are repeated with respect to other points of interest, and the group of obtained three-dimensional coordinates of the points of interest are inputted in a memory as the three-dimensional shape information of the object.
