Solid state image pickup device having optical black pixels with temperature characteristics above and below temperature characteristics of aperture pixels
Abstract:
There is provided a solid-state imaging device including: a plurality of aperture pixels configured to be used for capturing of an image; a plurality of first light-shielded pixels configured to be shielded from light for detection of an optical black level, a temperature dependence of a dark current in the first light-shielded pixels being larger than a temperature dependence of a dark current in the aperture pixels; and a plurality of second light-shielded pixels configured to be shielded from light for detection of an optical black level, a temperature dependence of a dark current in the second light-shielded pixels being smaller than a temperature dependence of a dark current in the aperture pixels.
