Patent ID: 7652708

Claim:
A solid-state imaging apparatus comprising: a pixel section having two-dimensionally arrayed pixels each having a photoelectric conversion means, a memory means for storing photoelectric conversion signal of said photoelectric conversion means, a transfer means for transferring said photoelectric conversion signal to said memory means, a reset means for resetting said memory means, a discharge means for discharging photoelectric conversion signal accumulated at said photoelectric conversion means, and a read means for reading photoelectric conversion signal of said memory means; an A/D converter for converting a pixel signal outputted from said pixel section into a digital signal; a noise suppressing means for suppressing noise of signal from said A/D converter, having a frame memory for storing signals from said A/D converter, and an adder for adding an output from said frame memory and signal from said A/D converter; and a controller for, in reading signal from the same one pixel of said pixel section, effecting control so that there is a difference corresponding to one frame period between timing at which a first signal level of said pixel after transfer of said photoelectric conversion signal to said memory means by said transfer means is read out and timing at which a second signal level of said pixel at the time of resetting said memory means by said reset means is read out.
