Title: ENCODING DEVICE, ENCODING METHOD, AND ENCODING PROGRAM
Abstract:
According to the present invention, a motion compensation prediction unit carries out a motion compensation prediction process for an image frame, and outputs a predicted frame and prediction information (24) used for the motion compensation prediction process. A conversion encoding unit encodes the difference between the image frame and the predicted frame, and outputs the difference as encoded data (25). A variable-length encoding unit (141) compresses the encoded data (25) as variable-length code data (27) by encoding the encoded data (25) by using a variable-length code. An addition control unit (142) adds the prediction information (24) to the variable-length code data (27).
