Abstract
A flicker is corrected with consideration given to the influence of noises. The present invention provides a flicker correction method in which a flicker is corrected by subtracting a flicker correction signal from an image signal, the method including the steps of removing noise from the flicker-corrected image signal by passing the latter through a low-pass filter, generating a correction error signal from the noise-removed, flicker-corrected image signal and the image signal not yet flicker-corrected, removing the image signal not yet flicker-corrected by passing the latter through a low-pass filter, and generating a flicker correction signal from the noise-removed image signal and correction error signal.
