Patent number: 9219925Abstract: The present invention relates to a displaying method for video image coded data which prevents deterioration of image quality of a video image as much as possible, and conceals, from an observer, deteriorated video quality caused due to a transmission error. The displaying method selects target image frames to be decoded and target image frames to be discarded, by performing error determination (32) in parallel with an error recovery process and other image restoration processes, and decodes (33) only the selected target image frames. A predetermined display device sequentially displays (34) only the decoded target image frames while adjusting a frame rate.Type: GrantFiled: January 4, 2011Date of Patent: December 22, 2015Assignee: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Yasuhito Fujita, Yoichi Hata, Yoshimitsu Goto, Toshiaki Kakii

Patent number: 8774002Abstract: The present invention relates to a traffic control apparatus and the like for optimizing a communication performance of each of local networks to be monitored. The traffic control apparatus (100) temporarily stores in the memory (120) communication band information items of relay nodes (211B, 212B, 213B) through the I/O (140). The controller (110) specifies a bottleneck relay node based on the obtained communication band information items, calculates transmittable/receivable bands to be allocated to the PCs (220B), and notifies the PCs (220B) of the calculated transmittable/receivable bands. In response to this notification, the PCs (220B) divide data to be transmitted, with the divided data corresponding to the allocated bands, and transmit the divided data to the Internet (10), in a manner that the divided data are arranged temporally evenly.Type: GrantFiled: July 21, 2010Date of Patent: July 8, 2014Assignee: Sumitomo Electric Industries, Ltd.Inventors: Yoichi Hata, Yasuhito Fujita, Yoshimitsu Goto, Toshiaki Kakii

Patent number: 8634553Abstract: A master key (K2,2) inputted by an input unit is stored in a storage unit. A matrix generating unit generates key element matrices (M1-M3) with respect to each of split keys (eR2, eR1, eR3) obtained by a key dividing unit dividing the master key (K2,2). To each coordinate entry of the key element matrices (M1-M3), operation data that successively obtained by repeating a hash operation with a one-way hash function is assigned, so as to maintain hierarchical nature of scalability (L). A key generating unit generates partial keys (K1,1-K2,2) corresponding to respective hierarchies of the scalabilities (R, L), on the basis of the key element matrices (M1-M3). These partial keys (K1,1-K2,2) are outputted to a coding unit or a decoding unit by an output unit.Type: GrantFiled: October 28, 2011Date of Patent: January 21, 2014Assignees: Sumitomo Electric Industries, Ltd., Tokyo Metropolitan UniversityInventors: Yoichi Hata, Toshiaki Kakii, Yasuhito Fujita, Yoshimitsu Goto, Hitoshi Kiya, Kiyoshi Nishikawa, Masaaki Fujiyoshi, Shoko Imaizumi

Patent number: 8553928Abstract: The present invention relates to an image processing method and image inspecting method with high versatility which enable efficient and highly accurate proof of authenticity of a digital image. The image processing method subjects at least a part of a digital image which can exist temporarily or continuously in a falsification-vulnerable environment, to a first morphology operation using a predetermined structuring element, to process the digital image. The image inspecting method subjects the digital image thus processed, to a second morphology operation using the same structuring element as in the first morphology operation. The morphology operations have the idempotent and the presence or absence of falsification can be detected by determining identity of images before and after the second morphology operation.Type: GrantFiled: March 6, 2007Date of Patent: October 8, 2013Assignees: Sumitomo Electric Industries, Ltd., Tokyo Metropolitan UniversityInventors: Hitoshi Kiya, Kiyoshi Nishikawa, Masaaki Fujiyoshi, Yoichi Hata, Toshiaki Kakii, Yoshimitsu Goto

Publication number: 20110299592Abstract: The present invention relates to a moving image data compressing method that enables improvement of the efficiency of compressing moving images and reduction in the processing load due to JPEG 2000 system. In the compressing method, in sequentially compressing, according to JPEG 2000, image frames that are disposed along a time axis without compressing the image frames in the time axis direction, a process of detecting movement of image elements is performed prior to EBCOT, with one or more code blocks, each of which being a minimum processing unit of the EBCOT, as one detection unit. While EBCOT is performed for each of code blocks that constitute a detection unit on which movement has been detected, EBCOT is skipped and predetermined data is supplemented for each of code blocks that constitute a detection unit on which movement has not been detected. Thus, the number of times of processing by EBCOT with a large computation amount can be reduced.Type: ApplicationFiled: November 26, 2009Publication date: December 8, 2011Inventors: Yasuhito Fujita, Toshiaki Kakii, Yoichi Hata, Yoshimitsu Goto

Publication number: 20100020966Abstract: The present invention relates to an encryption key generating method ensuring resistance to collusion attacks and achieving reduction in a key length of encryption keys corresponding to respective hierarchies of each scalability. In the encryption key generating method, an encryption key (K2,2) corresponding to data in the lowest hierarchies of hierarchical scalabilities (R, L) is divided as a master key by the number of hierarchies in scalability (R). Key element matrices (M1-M3) generated with respective split keys (eR2, eR1, eR3) are assigned operation data successively obtained by repeating a hash operation with a one-way hash function, so as to maintain hierarchical nature of scalability (L). Partial keys (K1,1-K2,2) corresponding to respective hierarchies of the scalabilities (R, L) are generated by combining key elements coordinately consistent among the key element matrices (M1-M3).Type: ApplicationFiled: November 4, 2008Publication date: January 28, 2010Applicants: SUMITOMO ELECTRIC INDUSTRIES, LTD., TOKYO METROPOLITAN UNIVERSITYInventors: Yoichi Hata, Toshiaki Kakii, Yasuhito Fujita, Yoshimitsu Goto, Hitoshi Kiya, Kiyoshi Nishikawa, Masaaki Fujiyoshi, Shoko Imaizumi
