Abstract:
A photoelectric conversion device includes a pixel unit including a photoelectric converter, an amplifier arranged on the output side of the pixel unit, an output unit arranged on the output side of the amplifier, a first restriction circuit, and a second restriction circuit. The first restriction circuit restricts, between the amplifier and the output unit, a noise level read out from the pixel unit via the amplifier in reading out the noise level from the pixel unit. The second restriction circuit restricts, between the photoelectric converter and the amplifier, a noise level to be provided to the amplifier in reading out the noise level from the pixel unit.
