ABSTRACT:
Solid-state imaging apparatus for producing an image signal has an active pixel region comprised of a plurality of active light receiving pixels for converting incident light to an image signal, and an optical black region disposed at the peripheral portion of the active pixel region and comprised of a plurality of pixels having a surface provided with a light shield. At least one pixel in the optical black region is located at a predetermined position and produces a position reference signal of a level which differs from that produced by the remaining pixels in the optical black region.
