PROBLEM TO BE SOLVED: To solve such problems of conventional television and movie production that 'wrinkes' of a human's skin part can not be emphasized (aging representation) and a 'complextion' can not be made better (representation of restoration of youth) without spoiling the fineness or texture of skin. SOLUTION: A specific amplitude band variation component separate type digital filter (βfilter) is constituted which newly has a specific amplitude band variation component calculation part 4 so as to actualize a 'wgood complextion' and 'wrinkle emphasis' with a natural feeling holding, for example, the fineness and texture of skin, a calculation part 4 selectively separates only a specific amplitude band variation component U (m, n) from an input image signal X (m, n) applied to this filter and outputs an image signal (m, n) generated by subtracting ('good complexion') the component from the input image signal or adds ('wrinkle emphasis') to the input signal according to an external correction indication. |
