Abstract: A technique for improving a compression rate without needing new determination information (encoding flag information) is provided. For compression of each area to be encoded, based on a skip mode (a process which does not compress information of the area to be encoded, but copies previous information of the area to be encoded), it is determined whether an existing predicted image generated by an existing encoding standard is used, or an interpolation predicted image newly generated by executing move searching between decoded images is used.

Abstract: Disclosed is an image processing technique which more suitably reduces flicker noise. An image display device is comprised of an input unit which inputs encoded image data containing images encoded by intraframe prediction and interframe prediction, an image decoder which decodes the encoded image data, a filter unit which filters the decoded images output from the image decoder, and a display unit which displays the image after filtering. The filter unit performs at least a process to correct the pixel values in a decoded image decoded by interframe prediction immediately preceding in time a decoded image decoded by intraframe prediction of the decoded images output from the image decoder.
