摘要： Video equalization including performing equalization such that a sequence of images have dynamic range (optionally other characteristics) that is constant to a predetermined degree, where the input video includes high and standard dynamic range videos and images from both. Equalization is performed with a common anchor point (e.g., 20% gray level, or log mean of luminance) input video and the equalized video, and such that the images determined by the equalized video have at least substantially the same average luminance as images determined by the input video. Other aspects are systems (e.g., display systems and video delivery systems) configured to perform embodiments of the equalization method.

摘要： Methods and apparatus are provided for backlighting a dual modulation display device. Each type of light source comprises a multi-primary light source having two or more primary color light emitters having different primary color characteristics from corresponding primary color emitters of other types of light source. Methods may comprise receiving illumination target values for a plurality of locations on the front modulator corresponding to the plurality of light sources, each of the locations on the front modulator configured to be illuminated by two or more of the plurality of light sources, determining primary color drive values source based on the primary color characteristics for that primary color and the illumination target value for the location corresponding to that light source, and driving the primary color light emitters or each type of light source based on the primary color drive values.
