Abstract:
A solid-state imaging device includes: a pixel section having pixels performing photoelectric conversion arranged in a matrix form; a pixel signal reading unit including an AD converting part that reads pixel signals in a unit of pixels, and compares a reference signal as a ramp waveform with the pixel signals to perform AD conversion; a clamp unit clamping the signal line with a clamp voltage such that the pixel signals are held at or greater than a set voltage; a correction bias circuit generating a clamp voltage according to a clamp voltage set value supplied and supplies the clamp voltage to the clamp unit; and a correction bias selecting unit selecting the clamp voltage set value such that the clamp voltage is generated in association with slope determining information for determining a slope of the reference signal, and supplies the clamp voltage set value to the correction bias circuit.
