    Abstract: The present invention can be applied to a CMOS image sensor in which each pixel circuit of an active pixel sensor array includes a photoelectric conversion element for converting input light into electricity and a switch transistor for controlling the supply of a reset voltage for resetting the photoelectric conversion element to a predetermined voltage, to the photoelectric conversion element. The CMOS image sensor comprises a control circuit for assigning a control signal applied to a control electrode of the switch transistor. The control circuit outputs a first voltage much higher than a supply voltage of the CMOS image sensor so as to make an ON resistance of the switch transistor sufficiently small in the first part of a reset period of the photoelectric conversion element and outputs a second voltage lower than a supply voltage of the CMOS image sensor in the latter part of a reset period of the photoelectric conversion element.
