Abstract
An imaging apparatus includes an integrating unit to integrate pixel values of pixels in each of a plurality of areas of an image; a holding unit to hold integration values generated by the integrating unit; an operating unit to operate a waveform of a differential value between integration values of the same areas in two images having a phase difference of flicker of 180 degrees; an extracting unit to extract phase and amplitude of the flicker on the basis of the waveform operated by the operating unit; a selecting unit to select a waveform of the flicker on the basis of shutter speed of the imaging apparatus; and a correcting unit configured to correct the pixel values of the pixels by using a correction value based on the flicker waveform selected by the selecting unit and the phase and amplitude extracted by the extracting unit.
