Abstract
A period for a long-term exposure signal is discriminated from a period for a short-term exposure signal. Based on a discrimination signal, an AGC gain selector switches a set value for the gain and a knee point selector switches a set value for the knee point, thereby independently controlling the gain and the knee point for each of the long-term exposure signal and the short-term exposure signal.
