Abstract

A frame encoding unit (13) creates individual image signal information from a moving picture signal Vin and outputs a frame code value InfVal_F as a value obtained by encoding the image signal information of each frame. A variable length encoding unit (16) dissolves the frame code value InfVal_F into a unit frame code value Val_F which is a basic unit of the encoding, converts the unit frame code value Val_F into a frame code word Code_F by using only a single code table (16a), and creates a frame stream by combining the converted frame code words Code_F. A multiplexer (17) multiplexes a conventionally prepared header stream with the aforementioned frame stream, thereby constituting an image encoding signal Str.
