Solid-state imaging device, method for driving the same, and camera system

摘要

A solid-state imaging device includes: a pixel unit in which pixels, each of which converts light into a pixel signal and accumulates the pixel signal in accordance with a light exposure period, are arranged in a predetermined color layout and first-color pixel horizontal rows containing first-color pixels and second-color pixel horizontal rows containing second-color pixels are alternately arranged in a vertical row direction; readout units that select n (n≧2) single-color pixel signals from the first-color or second-color pixels in the first-color or second-color pixel horizontal rows, perform 1/n thinning-out on the selected n pixel signals to reduce the number of pixel signals to 1/n, and read the resultant pixel signal for each of the colors; and column processing units that perform column processing on the pixel signals having undergone the 1/n thinning-out.
