A moving image encoder comprising: a contour extractor for dividing a local decoded image into a plurality of segments, and extracting contour information therein for each of an n number of frames, n being a natural number, in which encoding has been completed; a motion parameter extractor for extracting a set of motion parameters based on the contour information for each of an n number of frames in which encoding has been completed; a motion compensator for forming a prediction image based on the local decoded image, the contour information, and the set of motion parameters for each of an n number of frames in which encoding has been completed; an encoder for forming encoded information by means of quantizing a differential signal of the prediction image with a present frame; a local decoder for adding the prediction image to a signal formed by inverse quantization of the encoded information, forming a local decoded image, and storing this local decoded image into frame memory; and a transmitting unit for transmitting the encoded information and the set of motion parameters for each of an n number of frames in which encoding has been completed. <IMAGE> |
