Patent number: 7012635Abstract: A solid state image sensor controlled by a command signal. An area sensor has pixels arranged two-dimensionally. An interface is configured to receive the command signal. A selector is configured to select one of a plurality of readout schemes of reading out a pixel signal from the area sensor in accordance with the received command signal. A scanner is configured to scan the area sensor in accordance with the selected scheme selected, to read out the pixel signal from the area sensor. Processors subject the pixel signal to signal processing and output a digital video signal having a predetermined signal format. A motion vector detector is configured to detect a motion vector of an image based on the digital video signal and to output motion vector data to the interface. The area sensor, selector, scanner, processors, motion vector detector, and interface are mounted on a single chip.Type: GrantFiled: May 24, 2002Date of Patent: March 14, 2006Assignee: Kabushiki Kaisha ToshibaInventors: Masafumi Umeda, Hiroshi Suu
