A solid-state imaging apparatus includes: a pixel section where a plurality of pixels for effecting photoelectric conversion are two-dimensionally arranged, having an effective pixel section consisting of pixels for receiving object light and a reference pixel section consisting of pixels shielded from light; a first scanning circuit for sequentially setting to the pixel section the pixels to be read out a signal; a noise suppressing circuit for suppressing noise components of signals from the pixels based on a first control signal associated with sampling and holding of signals from the pixels and a second control signal associated with setting of clamping potential that are applied at respective predetermined timings; a second scanning circuit for sequentially reading signals of each pixel suppressed of the noise components; and a reference signal control section for applying the first and second control signals to the noise suppressing circuit so that it is brought into one or the other of a first condition where signals of the pixels shielded from light are inputted and a second condition where inputting of signals of the pixels shielded from light is lacked without changing an order according to which a release of sampling by the first control signal and a release of setting of clamping potential by the second control signal are effected, causing a generation of a first reference signal obtained in the first condition or a second reference signal obtained in the second condition as a signal corresponding to an optical black level.
