Abstract
A computation unit subtracts a prediction image from an input image. An orthogonal transformation unit applies orthogonal transformation to an output of the computation unit. A quantization unit quantizes an output of the orthogonal transformation unit. An encoding unit encodes an output of the quantization unit. A prediction mode determination unit determines a prediction mode from the input image. The prediction mode is different according to types of an I-picture, a P-picture and a B-picture.
