SOLID IMAGE PICKUP ELEMENT

摘要

PURPOSE:To correct variance in sensitivity among photocells with a simple constitution by individually setting the light transmissivity of each filter provided at the photodetection side of a photocell and the size of the aperture of each mask. CONSTITUTION:Photodetection surfaces of photocells 21-2n constituting the solid image pickup element are provided with filters 31-3n or masks controlling the quantity of light incident to each surface. In accordance with variance in sensitivity among photocells 21-2n, the light transmissivity of each of filters 31-3n or the size of the sperture of each mask is individually set to make an output even with uniform exposure.
