Patent number: 9800889Abstract: With use of a simplified program or calculating device for motion compensation, a video decoding device decodes video data compressed by motion detection operations on macroblock units, as in the MPEG-4AVC standard. The video decoding device splits compressed data blocks of the prescribed size, 16×16 pixels for instance, to generate sub-blocks, which are smaller than the blocks and on which the video decoding device is able to execute motion compensation operations. The video decoding device duplicates a motion vector assigned to a given block to generate an many motion vectors as there are sub-blocks in the given block, and executes motion compensation on each sub-block using the corresponding duplicate motion vector. Data resulting from the motion compensation operation on each sub-block is combined to obtain a target block corresponding to the given block.Type: GrantFiled: October 31, 2016Date of Patent: October 24, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hiroshi Amano, Takeshi Tanaka, Kouji Nakajima, Eiji Otomura

Publication number: 20060182182Abstract: An image processing system includes a memory management unit and an image decoding apparatus. The memory management unit receives first information regarding control of a frame memory, releases a frame in the frame memory in accordance with the first information, and outputs second information indicating the released frame. The image decoding apparatus decodes encoded image data into an image, and then stores the decoded image in the frame that the second information indicates. The image decoding apparatus then determines, according to the encoded image data, which image among the images stored in the frame memory is not to be referenced in decoding process, and outputs, as the first information, information regarding release of the frame in which that non-referenced image is stored.Type: ApplicationFiled: November 16, 2005Publication date: August 17, 2006Inventors: Koji Nakajima, Eiji Otomura, Manabu Kuroda
