IMPROVED COMPACTION IN REPRESENTATION OF NON-FRAME EDGE BLOCK OF IMAGE FRAME

摘要

PPROBLEM TO BE SOLVED: To provide technology using fewer bit for showing a prediction mode, which is used in order to encode part of a non-frame edge block of a frame. PSOLUTION: In one embodiment, fewer bits are used in a case of a boundary block of a slice or a slice group. In another embodiment, an adjacent block is encoded by using inter-frame coding or changeable intra-frame coding. When such an adjacent block cannot be used in order to predict the block, fewer bits are used. PCOPYRIGHT: (C)2009,JPO&INPIT
