Abstract
A method of determining when to activate a screen saver for a display device comprises selecting as a sample set a sparse subset of pixels which collectively form a display frame. An evaluation is performed of only the pixels in the sample set, to determine over a plurality of display frames whether pixels within the sample set have undergone a sufficient amount of change so that burn-in is unlikely. A determination is then made of whether to activate the screen saver based on a result of the evaluation.
