Patent ID: 7671915

Claim:
A solid-state imaging apparatus comprising: a pixel section having two-dimensionally arrayed unit pixels each having a first pixel and a second pixel respectively containing photoelectric conversion devices that are located at positions regarded as the same position at which image is formed by an imaging optical system; a reset control means for simultaneously resetting respectively independently all the said first pixels and all the said second pixels of each unit pixel arrayed in said pixel section; a difference signal output means for obtaining a difference signal between signals of said first pixel and of said second pixel; a control section for rendering control such that a reset is effected of signals of all the first pixels of said pixel section and, after a desired exposure time, a reset is effected of signals of all the second pixels of said pixel section by said reset control means, and then signals of the first pixel and of the second pixel are read out respectively in a simultaneous or substantially simultaneous manner immediately after the reset of signal of all the said second pixels by said reset control means so as to output a difference signal between these as imaging signal by said difference signal output means; and a characteristic difference correction means for correcting a characteristic difference between said first pixel and said second pixel.
