Abstract
An image data coding and decoding technique which realizes most efficient compression of the image data. The image data are input and separated into key frames and other intermediate frames. Per-pixel matching is computed between the key frames. A virtual intermediate frame between these key frames is generated by interpolating the matching-computed result. Difference is taken between the intermediate virtual frames and actual intermediate frames which have existed from the outset, so that the actual intermediate frames are encoded with the minimum quantity of codes.
