Publication number: 20190327465Abstract: There is provided an image processing device and a method that are capable of preventing transmission error propagation in an image. In a screen (a picture), a region called an intra stripe for intra prediction is assigned to a vertical direction, and the intra stripe is moved in a horizontal direction so that all the units of coding in the screen become the intra stripe. However, the regions to the right and the left of the intra stripe are limited to a left inter block and a right inter block in which inter prediction is performed. For example, the present disclosure can be applied to an image processing device, an image encoding device, an image decoding device, or the like.Type: ApplicationFiled: November 24, 2017Publication date: October 24, 2019Applicant: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventor: Toshiharu TSUCHIYA

Publication number: 20130058416Abstract: An image processing apparatus and an image processing method capable of further improving coding efficiency while suppressing an increase in a load. For example, in a case a macro block with a size of 16×16 pixels or less used in AVC is a coding process target, a motion search and compensation unit performs a motion search using an image with the original size which is not reduced. In addition, for example, in a case where an extended macro block with a size larger than 16×16 pixels is a coding process target, the motion search and compensation unit performs a motion search using a reduced image.Type: ApplicationFiled: April 25, 2011Publication date: March 7, 2013Applicant: SONY CORPORATIONInventors: Toshiharu Tsuchiya, Toru Wada

Publication number: 20070286281Abstract: 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.Type: ApplicationFiled: January 27, 2005Publication date: December 13, 2007Inventors: Toshiharu Tsuchiya, Kazushi Sato, Toru Wada, Yoichi Yagasaki, Makoto Yamada

Patent number: 6950074Abstract: The present invention relates to an electronic device that suppresses reduction in reception sensitivity and occurrence of distortion when IC cards are used while stacked. A loop antenna equipped on the IC card has up to four turns, and is designed so that one turn, for example, has a first linear portion, a first curved line portion, a second linear portion, and a second curved line portion. When two electronic devices having a first loop antenna and a second loop antenna, respectively, are stacked onto one another, the corners of the loop antennas do not overlap. For example, the corner formed by first curved line portion and the second linear portion of the first loop antenna is overlapped with the first curved line portion of the second loop antenna. The first and second loop antennas are shaped such that when two electronic devices are stacked, their respective loop antennas are superimposed in the opposite direction so that the corners are not overlapped and the amount of overlap as a whole is reduced.Type: GrantFiled: January 24, 2002Date of Patent: September 27, 2005Assignee: Sony CorporationInventors: Shigeru Arisawa, Osamu Ishii, Toshiharu Tsuchiya

Patent number: 4498415Abstract: Can end disks have annular, curled rims on which a sealing composition is applied as a coat to form airtight seals when the end disks are subsequently attached to can bodies. The sealing composition is sprayed onto the curled rim of each can end disk by an overlying spray nozzle while the disk is being rotated on a rotary rest in a coating machine. For detecting uncoated regions on the curled rim of the can end disk, a photodetector is positioned over the rim of the disk on the rotary rest, with a preassigned angular spacing between the photodetector and the spray nozzle. The detection of uncoated regions is essentially concurrent with the application of the sealing composition. Since the output from the photodetector represents a nonfaulty uncoated region (i.e. a region not yet coated), in addition to a possible faulty uncoated region (i.e.Type: GrantFiled: October 25, 1983Date of Patent: February 12, 1985Assignee: Shinryo Seikan Kabushiki KaishaInventors: Toshiharu Tsuchiya, Mamoru Iwata
