SOLID-STATE IMAGING DEVICE AND CAMERA SYSTEM

摘要

According to one embodiment, a solid-state imaging device comprises a pixel array wherein unit patterns are placed repeatedly the unit pattern along vertical and horizontal directions. The unit pattern has at least four pixels arranged vertically and two pixels arranged horizontally. The unit pattern is formed of pixels of a first group including two first green pixels and pixels of a second group including two second green pixels. The two first green pixels are arranged vertically with one of a red pixel and a blue pixel in between, and the two second green pixels are arranged vertically with one of a red pixel and a blue pixel in between.

1. A solid-state imaging device comprising:
a pixel array wherein a first group of pixels which are exposed for a first time and a second group of pixels which are exposed for a second time shorter than the first time are Bayer arranged along a vertical direction and a horizontal direction, the pixels accumulating signal charge generated according to the amount of incident light; a control unit that controls reading signals from the first and second groups of pixels; and a signal processing unit that performs high dynamic range composition of signals from the first group of pixels and signals from the second group of pixels, wherein in the pixel array, unit patterns, in each of which at least four pixels are arranged vertically and two pixels are arranged horizontally, are placed repeatedly the unit pattern along vertical and horizontal directions, and wherein the unit pattern is formed of pixels of the first group including two first green pixels arranged vertically with one of a red pixel and a blue pixel in between and pixels of the second group including two second green pixels arranged vertically with one of a red pixel and a blue pixel in between.
