Patent attributes
A solid-state imaging apparatus including: a pixel section having two-dimensionally arrayed pixels each having a first photoelectric conversion device and a second photoelectric conversion device located at positions regarded as the same position at which image is formed by an imaging optical system and a means for independently resetting each of signals accumulated at the first photoelectric conversion device and the second photoelectric conversion device; a reset control means for executing a resetting of the signal of all first photoelectric conversion devices of the pixel section as a first resetting operation, and executing, after a desired exposure time subsequent to the first resetting operation, a resetting of the signal of all second photoelectric conversion devices of said pixel section as a second resetting operation; a read means for reading simultaneously or almost simultaneously signals of the first photoelectric conversion device and the second photoelectric conversion device of each pixel starting immediately after the second resetting operation; and a difference signal output means for outputting as imaging signal the difference signal between the first photoelectric conversion device and the second photoelectric conversion device of said each pixel.
