摘要： A video encoder that encodes each of a plurality of blocks obtained by dividing an input image, includes: a definition unit configured to define a valid area which is allowed to be used as reference in a reference image in interframe coding; a detection unit configured to detect a reference area in the reference image for a target block; a predicted image generation unit configured to generate a predicted image by outputting an image of the reference area for the reference area belonging to the valid area and outputting a complementary image for the reference area not belonging to the valid area; and a coding unit configured to encode the input image using the predicted image, wherein valid area information indicating the valid area is transmitted to a video decoder, for each group of a plurality of blocks.

摘要： A method of coding (decoding) an image comprised of a pixel block divided into a plurality of sub-blocks, which method autonomously determines an order of optimal coding (decoding) adapted to a correlation between adjacent sub-blocks without providing additional information. This method pays attention to context information accompanying the image information and instructing a correlation direction between pictures and so on, sequentially predicts a reference sub-block serving the best coding (decoding) efficiency among adjacent reference sub-blocks to be referred to for the coding (decoding) based on the correlation direction, and determining the order of coding (decoding) according to this prediction.
