Abstract
Even when the light intensity of the light source varies, the flicker correction can thus be made flexibly. The present invention provides a flicker correction method comprising the steps of predicting, from an image of a present flicker-corrected frame, a flicker of an image of a next frame to generate two types of flicker images having flickers different in level from each other added thereto, detecting a flicker component through comparison between the generated two types of flicker images and an image of an input next frame, generating a flicker correction value on the basis of the detected flicker component, and making flicker correction by adding the generated flicker correction value to an input image frame by frame.
