IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE, IMAGE ENCODING METHOD, AND IMAGE DECODING METHOD |
摘要 |
Disclosed is an image encoding device which is constructed in such a way as to include an encoding mode determining unit 4 for evaluating the degree of efficiency of encoding of a difference image A which is the difference between an image of a macroblock to be encoded, and a prediction image A generated by a motion-compensated prediction unit 2 in a motion prediction mode A, and also evaluating the degree of efficiency of encoding of a difference image B which is the difference between the image of the macroblock to be encoded, and a prediction image B generated by the motion-compensated prediction unit 2 in a motion prediction mode B, and for selecting a difference image having a higher degree of encoding efficiency. |
