Patent number: 10116936Abstract: The present invention makes moving-image coding and decoding with low power consumption possible even when a Context-based Adaptive Binary Arithmetic Coding (CABAC) process is used. A preprocess for coding an image is executed for each macro block (MB), the MB information that is the result of the process is written into a storage unit in the order in which the MBs were processed, and the MB information stored in the storage unit is read out in order of raster and the MBs are coded. When the coded image is decoded, the MBs constituting the coded image are decoded in order of raster, the MB information that is the result of the decoded process is stored in the storage unit, and a decoded information readout process that is a post-process for decoding the image is executed in the order in which the MBs were processed.Type: GrantFiled: August 28, 2015Date of Patent: October 30, 2018Assignee: Hitachi Information & Telecommunication Engineering, Ltd.Inventors: Yuusuke Yatabe, Hironori Komi, Yoshimasa Kashihara, Kazunori Saito

Patent number: 9509992Abstract: An image compression/decompression device achieving increased utilization efficiency of the memory bandwidth in the access to the memory used for the compression/decompression operation while maintaining ill effect on the images at a low level is realized. The image compression/decompression device comprises a data conversion unit which reduces the data access rate when original images (as input images at the time of performing the compression) and reference images (used for performing the interframe prediction) are stored in the memory by accessing the memory. The access to the memory is performed in an address sequence (order) that differs between data write and data read. This makes it possible to increase the utilization efficiency of the memory bandwidth, and further to reduce the capacity of the buffer memory used for the data read.Type: GrantFiled: December 19, 2013Date of Patent: November 29, 2016Assignee: HITACHI INFORMATION & TELECOMMUNICATION ENGINEERING, LTD.Inventors: Hironori Komi, Yusuke Yatabe, Kyohei Unno, Yoshiyuki Motoba, Toshiaki Hori, Yoshimasa Kashihara, Toshikazu Yanagihara
