摘要:
A solid-state image pickup device which includes, on a semiconductor substrate, an image pickup area which includes plural columns of pixels, and plural column amplifier circuits each provided at each column of pixels or at every plural columns of pixels, wherein: each of the column amplifier circuits includes at least two amplifier circuit stages; a preceding amplifier circuit is a variable-gain amplifier circuit and the switchable gains include plural one or more gains; and a subsequent amplifier circuit is capable of amplifying, at one or more gains, the signal amplified at one or more gains in the preceding amplifier circuit.
