Abstract
An apparatus includes: an object data storage section that stores polygon identification data for polygons of an object to be displayed; a reference image data storage section that stores data of reference images each representing an image when a space including the object to be displayed is viewed from one of a plurality of prescribed reference viewing points, and further stores polygon identification data corresponding to each reference image; a viewing point information acquisition section that acquires information relating to a viewing point; a projection section that represents on a plane of a display image the position and shape of an image of the object when the space is viewed from the viewing point; a pixel value determination section that determines the values of pixels constituting the image of the object in the display image, using the values of the pixels representing the same image in one or more of the plurality of reference images; and an output section that outputs the data of the display image; wherein for a subject pixel, the pixel value determination section is arranged to determine the position on a reference image corresponding to the position of the subject p…
