Patent ID: 7812301

Claim:
A solid-state imaging device, comprising: a two-dimensional pixel array area in which each unit pixel includes a photoelectric conversion element converting optical signals to signal charges and a transfer gate transferring the signal charges which have been photoelectrically converted in the photoelectric conversion; 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 that of the first control voltage to the control electrode of the transfer gate; a third supply voltage control means for supplying a third control voltage having the same voltage value as that of any one of or the plural second control voltages once or plural times prior to one supply of any one of the plural second control voltages or plural supplies of the plural second control voltages to the control electrode of the transfer gate; a first driving means for performing driving of reading out signal charges transferred by the transfer gate when the first control voltage is supplied; and a second driving means for performing driving of reading out signal charges transferred by the transfer gate once and more when the second control voltage is sequentially applied.
