Abstract:
1. A solid-state imaging device comprising: a pixel section having a plurality of pixels performing photoelectric conversion arranged in a matrix form; a pixel signal reading unit including an analog-digital (AD) converting part that reads pixel signals from the pixel section to a signal line in a unit of a plurality of pixels, and compares a reference signal as a ramp waveform with the pixel signals to perform AD conversion; a clamp unit that clamps the signal line with a clamp voltage in such a way that the pixel signals are held at or greater than a set voltage; a correction bias circuit that generates 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 that selects the clamp voltage set value in such a way 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.
