摘要

The present invention relates to a method for maintaining the perceived brightness a video image displayed on a display device, comprising the steps of:- obtaining (100) at least one highlight area of said video image comprising at least one highlight pixel,- reducing (110) at least a luminance level of said at least one highlight pixel by a given luminance amount, and- redistributing (120) said given luminance amount to pixels in the neighborhood of said at least one highlight pixel in order to add a glare effect around said at least one highlight pixel.
