Abstract:
After an input image signal (2000) of a smaller resolution is encoded by an encoder (20), an input image signal (1000) of a greater resolution is subjected to motion compensation processing by a motion compensation unit (102) according to motion information (1998), thereby generating a prediction error signal (1001). Simultaneously with this, an enlarged decoded image (2003) obtained by enlarging the decoded image (2002) obtained by an encoder (20) is subjected to motion compensation processing by a motion compensation unit (103) according to the motion information (1998), thereby generating a prediction error signal (2005). By referencing the prediction error signal (2005), the prediction error signal (1001) is subjected to conversion encoding, quantization, and entropy encoding.
