Publication number: 20140078848Abstract: In one embodiment, a semiconductor memory device receives a refresh command and address information, and supplies a refresh control signal and the address information in common to core chips. Each of the core chips includes a layer-address comparison circuit that determines whether the address information assigns an own core chip, and a refresh control circuit that refreshes an own memory cell based on the refresh control signal when the address information assigns the own core chip. With this arrangement, a memory capacity of a chip that is refreshed by a refresh command for one time is reduced, and therefore a shortest issuing interval of a refresh command can be shortened.Type: ApplicationFiled: November 20, 2013Publication date: March 20, 2014Inventors: Junichi HAYASHI, Akira IDE

Patent number: 8358353Abstract: The invention enables a verifier to easily confirm that the image data was captured in the multiple exposure mode, and also to easily confirm which area in the image captured in the multiple exposure mode was greatly affected by multiple exposure. An image generating unit generates exposure image data pieces by exposing an image sensor a plurality of times. An image composition unit combines exposure image data pieces to generate a single piece of composite image data. A reference image generating unit generates reference image data composed of data pieces for distinguishing pixel positions at which the exposure amount exceeds a threshold from the other pixel positions. A verification data generating unit generates verification data for determining whether alteration has been made from the composite image data and the reference image data to output a single file.Type: GrantFiled: January 19, 2011Date of Patent: January 22, 2013Assignee: Canon Kabushiki KaishaInventors: Junichi Hayashi, Nobuhiro Tagashira, Kazuya Kishi, Yasuhiro Nakamoto, Yoshiharu Imamoto

Patent number: 8340347Abstract: This invention provides a technique of preventing determination of image alteration when digital image data has undergone, e.g., rotation without any substantial change in contents. To do this, an area separation processing unit separates image data into areas. For each of the separated areas, an area feature value calculator calculates an area feature value independent of the coordinate information of the image. An area order sorter sorts the separated areas in accordance with the calculated area feature values. A validation data generation processing unit generates validation data based on the sort result.Type: GrantFiled: November 23, 2009Date of Patent: December 25, 2012Assignee: Canon Kabushiki KaishaInventors: Junichi Hayashi, Yoshiharu Imamoto, Nobuhiro Tagashira, Kazuya Kishi, Yasuhiro Nakamoto, Kazuomi Oishi
