Dynamic image processing apparatus and method
 An image processing apparatus and method for accurately reproducing an edge part at which luminance (brightness) abruptly changes with respect to dynamic image information. A dynamic image memory records a plurality of frames of information of the dynamic image. An information change analyzing unit performs a three-dimensional analysis for the dynamic image information. A characteristic point detection unit detects locations at which characteristic points exist by processing the results of the analysis. The characteristic point encoding unit further processes the results of analysis of the characteristic point detection unit and expresses the locations at which the characteristic points exist as a curved surface. An information encoding unit executes the analysis for obtaining information necessary for reproducing an input dynamic image at the characteristic points. A total coding unit codes output information of the characteristic point encoding unit and a subtraction circuit.
