Abstract
A method for reducing artefacts caused by the presence of flicker during image capture. The method comprises performing image capture to produce image capture data corresponding to an image capture scene, the image capture data including a first image having a first exposure and a second image having a second exposure. The image capture data is processed to: (a) detect a discrepancy in the second image with respect to the first image; and (b) determine flicker indication data indicative of a presence of flicker in the second image. The discrepancy is corrected in dependence upon the flicker indication to produce a flicker-reduced version of the second image.
