Abstract
Included are: a prefilter (101) for outputting, based on filter characteristics control data, predetermined frequency components in an input video signal as current image data; encoding means (116) for subjecting the current image data to an encoding process, and outputting encoding parameters together with a bit stream corresponding to current image data as a result of the encoding process; and filter control means (117) for outputting the filter characteristics control data that is set based only on one or two of the encoding parameters.
