ABSTRACT:
Methods and systems process image data made up of a series of frames for displaying on a dual modulation display system having a first modulator disposed to illuminate a second modulator. A first modulation signal and a luminance map are not calculated for every frame. Instead, certain frames referred to as “key frames” are used to provide the first modulation signal and the luminance map for at least some other frames.
