ABSTRACT:
A system and method in which a fluorescent light flicker characteristic of an XY addressing type image pickup device such as a CMOS image pickup device is accurately detected and reliably and sufficiently reduced. This is achieved through signal processing without using a photosensitive element regardless of the level of a video signal of a subject and the type of a fluorescent lamp. A signal In′(x,y) is an RGB primary color signal or a luminance signal, each containing a flicker component. The signal In′(x,y) is integrated over a duration of time equal to or longer than one horizontal period, and a difference value between the integrated values of adjacent fields is normalized by the average value of the integrated values of three consecutive fields.
