Abstract

A pseudo-image signal producing section produces a pseudo-image signal imitating an actual image signal. An amplitude detection section detects the amplitude of the pseudo-image signal having passed through a complex filter circuit. A filter control section controls an element value control section in the complex filter circuit so as to decrease the detected amplitude. The element value control section performs an element value adjustment so that absolute element values of a pair of elements corresponding to each other in two filter circuits in the complex filter circuit increase/decrease in opposite directions.
