Conventional reset ability is fixed of resetting an amplifier in a charge-to-voltage conversion amplifier. According to an imaging device of this invention, reset ability may be switched. For this purpose, a reset ability-switching function is provided for switching power consumption of the amplifier as reset ability of resetting an amplifier in the charge-to-voltage conversion amplifier, which may realize free switching of the power consumption as the reset ability and adaptability to various types of charge-to-voltage conversion. Accordingly, heat generation may be suppressed by switching power consumption to the lower one in the case where heat generation possibly increases.
