摘要：
A readout circuit includes: an amplifier (408); and offset controllers (415 and 416) configured to set an output offset voltage of the amplifier, wherein the readout circuit operates in first and second modes, in the first mode, a first voltage, and thereafter a second voltage lower than the first voltage, are input into the amplifier, in the second mode, a third voltage, and thereafter a fourth voltage higher than the third voltage, are input into the amplifier, and the offset controller switches the output offset voltage of the amplifier, between the first and second modes.
