Abstract
A solid state image sensing device provided with a gamma correction circuit which corrects a logarithmically converted value derived from the logarithmic conversion of individual pixel data output from individual photoelectric conversion elements, thereby easily correcting discrepancies and differences in the gamma characteristics of the individual pixels of a photoelectric conversion element which converts a light signal to an electrical signal.
