the invention relates to a method , device and computer - program product for suppression of undesired temporal variations , notably flicker , in a sequence of video frames . histogram - based and similar approaches generally do not remove all flicker . features that are resolved only in portions of the flicker cycle will manifest themselves as residual flicker . this effect is near - universal in bright regions of a scene . the inventive solution is a mapping that aims to resolve in the output only those features that are resolved in all frames of the flicker cycle . use of time - maximal quantile values may preserve non - resolution of such image features that are unresolved due to intermittent bright saturation . thus , in one embodiment , a reduction of resolution is attained by means of a pixel - value mapping based on selecting , over a time window , maximal and minimal quantile values , with maximal values being used for bright spatial regions and minimal values for dark spatial regions .
