Abstract
PURPOSE: To correct a lack signal falsely by storing previously all picture elements of defective sensitivity on the surface of a solid image pickup element into a ROM and by utilizing these stored output signals.
CONSTITUTION: Before design of a solid image pickup device, solid image pickup element 1 is subjected to detection test previously for picture elements of defective sensitivity, whose outputs are zero or very small, output of picture elements of solid image pickup element 1, and coordinates indicating positions of these picture elements of defective sensitivity are stored in ROM 6. During the period when stored coordinates are read out from ROM 6 where the clock signal from clock signal generator 4 and horizontal and vertical synchronizing signals from synchronizing signal generation circuit 5 are supplied, the output sample hold pulse of circuit 7 holds the output signal of amplifier 8 in sample hold circuit 9.
