Abstract

An image-processing device is provided with: a flicker detecting portion that detects a flicker component in an input image signal for each frame and that generates a first signal; a storing portion that stores the generated first signal for a plurality of latest continuous frames; a phase-displacement detecting portion that selects, from the stored past first flicker correction signals, the first signal having substantially the same phase as the most-recent first signal, and that detects a phase displacement level with respect to the most-recent first signal; a phase-displacement correcting portion that corrects the selected past first signal on the basis of the detected phase displacement level; an infinite-impulse-response combining portion that generates a second signal by combining, at a predetermined ratio, the corrected past first signal and the most-recent first signal; and a flicker correcting portion that corrects the input image signal on the basis of the generated second signal.
