ABSTRACT:
A solid-state imaging device, includes: a pixel array area including an unit pixel having a photoelectric conversion element and a transfer gate; a first supply voltage control means for supplying a first control voltage to a control electrode of the transfer gate; a second supply voltage control means for sequentially supplying one or plural second control voltages having a voltage value different from the first control voltage to the control electrode; a third supply voltage control means for supplying a third control voltage having the same voltage value as the second control voltages once or plural times prior to one or plural supplies of the second control voltages; a first driving means for reading signal charges from the transfer gate when the first control voltage is supplied; and a second driving means for reading signal charges from the transfer gate once and more when the second control voltage is sequentially applied.
