Patent number: 7911507Abstract: In a pixel unit, cells are arranged in rows and columns two-dimensionally. Each of the cells accumulates signal charge obtained by photoelectrically converting light incident on photoelectric conversion section and outputs a voltage corresponding to the accumulated signal charge. On the cells, W, R, G, and B color filters are provided. Analog signals output from the W pixel, R pixel, G pixel, and B pixel are converted into digital signals by an analog/digital converter circuit, which outputs a W signal, an R signal, a G signal, and a B signal separately. A W signal saturated signal quantity is controlled by a saturated signal quantity control circuit. Then, a signal generator circuit corrects the R signal, the G signal, and the B signal using the W signal, the R signal, the G signal, and B signal output from the analog/digital converter circuit and outputs the corrected R, G, and B signals.Type: GrantFiled: December 31, 2007Date of Patent: March 22, 2011Assignee: Kabushiki Kaisha ToshibaInventors: Yoshitaka Egawa, Hiroto Honda, Yoshinori Iida, Goh Itoh
