Claim Text:
1. A solid-state imaging device comprising: a pixel array which includes pixels arranged in a horizontal direction and a vertical direction and generates signal charges in accordance with an amount of incident light onto each of the pixels; a first AD converting unit and a second AD converting unit which include AD converters arranged in a horizontal direction, each of the AD converters being configured to convert an analog signal read out from the pixels into a digital signal; a first AD converting unit group including the first AD converting unit and the second AD converting unit; and a second AD converting unit group including the first AD converting unit and the second AD converting unit and disposed in a vertical direction so as to face the first AD converting unit group with the pixel array interposed therebetween, wherein each of the pixels includes four small pixels including two small pixels arranged in a horizontal direction in a first row and two small pixels arranged in a horizontal direction in a second row, the four small pixels including at least two small pixels having different optical sensitivities from each other, the two small pixels in the first row are connected to AD converters in the first AD converting unit, the two small pixels in the second row are connected to AD converters in the second AD converting unit, the first AD converting unit group and the second AD converting unit group share a region of the pixel array to perform AD conversion, and a range of the region where the first AD converting unit group performs the AD conversion and a range of the region where the second AD converting unit group performs the AD conversion vary.
