According to an information signal correction processing apparatus of the invention which includes a plurality of clip circuits, a knee circuit, an adder, and a controller, an information signal which has been obtained through the clip circuits by clipping an input information signal in accordance with a plurality of clipping characteristics which have been arbitrarily set and an information signal which has been obtained through the knee circuit by voltage dividing the input information signal in accordance with a voltage dividing ratio which has been arbitrarily set are added by the adder and, when the resultant signal is outputted, the plurality of clipping characteristics and the voltage dividing ratio are respectively controlled by the controller, so that the information signal can be processed without being deteriorated.
