ABSTRACT:
A flicker correction apparatus for correcting a flicker component of an image signal obtained by imaging an object using an imaging device is provided. The apparatus comprises an image average calculation section for calculating an average of the image signal, a flicker frequency calculation section for calculating a flicker frequency, a flicker data extraction section for extracting flicker data using the average of the image signal and the flicker frequency, a flicker determination section for determining the presence or absence of a flicker phenomenon using the flicker data, a flicker correction amount calculation section for calculating a flicker correction amount using the flicker data, and a flicker correction section for removing the flicker component of the image data using the flicker correction amount.
