SOLID-STATE IMAGING DEVICE AND CAMERA SYSTEM

摘要

A solid-state imaging device includes: a pixel unit in which pixels are arranged in a matrix pattern; and a pixel signal read-out unit including an AD conversion unit performing analog-to-digital (AD) conversion of a pixel signal read out from the pixel unit, wherein each pixel included in the pixel unit includes division pixels divided into regions in which photosensitivity levels or electric charge accumulating amounts are different from one another, the pixel signal reading unit includes a normal read-out mode and a multiple read-out mode, and includes a function of changing a configuration of a frame in accordance with a change of the read-out mode, and wherein the AD conversion unit acquires a pixel signal of one pixel by adding the division pixel signals while performing AD conversion for the division pixel signals.

1. An imaging device, comprising:
a pixel unit that has a first, a second, a third and a fourth pixel, wherein the first pixel is adjacent to the second pixel along a row direction, and the third pixel along a column direction, wherein the fourth pixel is adjacent to the second pixel along the column direction, and the third pixel along the row direction, wherein the first and the fourth pixels have a first sensitivity or a first exposure time and the second and the third pixels have a second sensitivity or a second exposure time, and wherein a first pixel signal output from the first pixel and a fourth pixel signal output from the fourth pixel are added.
