ABSTRACT:
A shading correction circuit for correcting the shading distortion of a photoelectric conversion device including a plurality of arrayed photocells, has a memory for storing data on the output characteristics of each pixel, represented by image signals having a given level outputted by the photoelectric conversion device a plurality of image pickup times. Thereby, the data on the output characteristics of each pixel stored in the storing means is read by desirably switching the order of the image pickup for each pixel to provide shading correction data. Noise or irregularities which readily appear on the output picture after shading correction are reduced.
