Patent number: 7719582Abstract: When pixel signals are separately read from a plurality of horizontal signal lines to achieve high-speed processing, color difference in image signals and stripes are eliminated. In the operation of reading the pixel signals from the (2n)th row, the pixel signals from R pixels on odd columns are output to an output system A through a horizontal signal line (60A). On the other hand, the pixel signals from Gr pixels on even columns are output to an output system B through a horizontal signal line (60B). In the operation of reading the pixel signals from the (2n+1)th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line (60B) by the switching operation in a switching circuit (50). Similarly, the pixel signals from B pixels on the even columns are output to the output system A through the horizontal signal line (60A) by the switching operation in the switching circuit (50).Type: GrantFiled: November 21, 2003Date of Patent: May 18, 2010Assignee: Sony CorporationInventors: Takamasa Wada, Eiichi Funatsu, Keiji Mabuchi, Ken Nakajima, Takashi Abe, Tomoyuki Umeda, Nobuo Nakamura, Hiroaki Fujita, Hiroki Sato

Patent number: 7623172Abstract: A solid state imaging device having an X-Y addressable solid state imaging device with color filters and a driving unit which reads out pixel information of a same color filter in a unit pixel block as pixel information for one pixel simulatively. A predetermined color coding for the pixels has two rows and two columns. When k is a positive integer equal to or larger than 0, with (2k+3)×(2k+3) pixel blocks as unit pixel blocks, the driving unit reads out pieces of pixel information of the same color filter in each of the unit pixel blocks, the driving unit reads out pieces of pixel information of a same color filter in each of the unit pixel blocks simulatively as pixel information for one pixel in a state in which the unit pixel blocks are laid without overlapping one another, and the driving unit averages the added pieces of pixel information and outputs the averaged pieces of pixel information.Type: GrantFiled: February 20, 2004Date of Patent: November 24, 2009Assignee: Sony CorporationInventors: Takamasa Wada, Eiichi Funatsu, Keiji Mabuchi, Ken Nakajima, Katsuaki Hirota, Nobuyuki Satou, Takashi Abe, Tomoyuki Umeda, Nobuo Nakamura, Hiroaki Fujita, Hiroki Sato
