Claim Text:
1. A method for processing an image, the method comprising: receiving a plurality of input pixel values associated with a video; determining that a first portion of pixel values included in the plurality of input pixel values is within a first set of excluded values; and dithering the first portion of pixel values to generate a first plurality of dithered values, wherein each dithered value included in the first plurality of dithered values is not within the first set of excluded values, and a first average pixel value associated with the plurality of input pixel values is substantially similar to a second average pixel value associated with both the first plurality of dithered values and a plurality of pixel values that are spatially proximate to the first plurality of dithered values, wherein the first set of excluded values is associated with perturbations in a pixel value mapping that maps gray level values to values selected from the group consisting of voltage values, electrical current values, and electrical charge values.
