Abstract
There are provided a multi-viewpoint image database for holding images from a plurality of different viewpoints, a viewpoint detector for detecting a position of the observer's viewpoint, and a viewpoint parameter calculating portion for obtaining a viewpoint parameter from an output from the viewpoint detector. Further, a pixel value producing portion is provided for calculating a parameter necessary for reconstruction of image from the type of display screen and the viewpoint parameter, calculating with the parameter to which pixel in the images in the multi-viewpoint image database each pixel in a reconstructed image corresponds, and extracting corresponding pixels from the multi-viewpoint image database.
