Abstract:
A method of displaying an image on a display device in a plurality of periods called sub-fields, wherein the display device is capable of generating, in each of the sub-fields, a respective illumination level, the method comprising the steps:defining a set of combinations of sub-fields, each combination in the set corresponding with a respective intensity level of the display device; for each pixel of the image, selecting a particular combination of sub-fields from the set in conformance with the intensity value of the pixel; and for each pixel of the image, sending a representation of the selected combination of sub-fields to the display device for displaying the particular pixel, characterized in that the combinations of sub-fields in the set correspond with respective intensity levels that are uniformly spaced on a perceptual scale, wherein the combinations of sub-fields in the set are formed by sub-fields that are temporally adjacent.
