Abstract
A coding apparatus for a moving object image input signal such as a television signal detects an uncovered background area appearing upon movement of a moving object in the moving object image input signal and encodes an image signal corresponding to the uncovered background area according to intraframe correlation instead of interframe correlation. The coding apparatus includes a noise reduction circuit for decreasing a noise reduction level for the signal corresponding to the uncovered background area.
