    摘要: In a picture information encoding apparatus that outputs picture compression information according to a picture encoding system such as MPEG4/AVC, when it is determined whether the mode of a predetermined block is a skip mode or a spatial direct mode, moving vector information and so forth for all of predetermined adjacent blocks needs to have been computed. However, when each block is processed in parallel to speed up the entire processes, moving vector information and so forth of the predetermined adjacent blocks may not be always obtained. In this case, moving vector information and so forth of neighbor blocks instead of adjacent blocks are pseudo-used to determine the mode of the block without need to wait until moving vector information and so forth of adjacent blocks have been computed.

    摘要: An object of the invention is to provide a prediction compensation device and its method in which the processing efficiency of the overall coding process is enhanced. The address of an object pixel block serving as a pixel block of prediction object among a plurality of pixel blocks is detected, a first search range or a second search range narrower than the first search range is decided as the search range of a motion vector for the object pixel block on the reference frame according to the detected address, and the motion vector is searched for from the decided search range around the predictor of the motion vector based on the surrounding pixel blocks adjacent to the object pixel block.

    摘要: A data processing apparatus, a method of data processing and an encoding device are provided. The data processing apparatus is capable of encoding all motion compensation block data, wherein, when generating for example a motion vector MV of a motion compensation block data A in macro block data MB_X, when the motion vectors MV of the motion compensation block data B1, B2, and B3 at the periphery of that are not generated, a predictive vector generation unit of a motion prediction and compensation circuit generates a predictive motion vector PMV of the motion compensation block data A by using already generated motion vectors MV of motion compensation block data C1, C2, and C3 in the adjacent macro block data MB_Y in place of them.

    摘要: The present invention is directed to an image information encoding apparatus, used in receiving compressed image information through network media when processing of such compressed image information is performed on storage media. A picture sorting buffer delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to P picture on the basis of that command.
