Abstract
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.
