Abstract
Of the output signals of a solid state image sensor, only the signals in a vertical OB line period are selected by an OB line selector. A level adjusteradjusts the level of a past vertical OB line signal read out from the line memoryduring a first vertical OB line period of a frame where the amplification factor of an amplifierhas changed, and outputs the same. A subtractorsubtracts the signal whose level has been adjusted from a current vertical OB line signal. A multipliermultiplies, via a selector B, the signal after subtraction by a cyclic coefficient Kfor the first vertical OB line period of the frame where the amplification factor has changed. A subtractorsubtracts the multiplication result from the current vertical OB line signal, and rewrites the subtraction result to the line memory
