A method for flicker detection based on a plurality of images and associated circuit is provided. The method includes providing an integrated flicker signal for each image, including accumulating pixel data of a number of pixels along each row; performing a motion compensation including: comparing two integrated flicker signals of two images, and accordingly providing a flicker signal difference; performing a flicker feature extraction including: applying a frequency analysis on the flicker signal difference, and accordingly providing a normalized flicker feature value; and performing a flicker determination, including: calculating a likelihood according to the normalized flicker feature value, and, according to the likelihood, determining whether a flicker-free hypothesis should be rejected in favor of a flicker-suffered hypothesis. ***** |
