ABSTRACT:
According to one embodiment, a method for compensating for inadequate bit resolution in a light processing system includes receiving a plurality of values each indicative of an intensity level for a pixel to be displayed. Each of the values is represented by a plurality of bits of data. The method also includes determining a quantization step size for the plurality of bits of data. For at least one particular pixel of the pixels, a set of consecutive pixels including the particular pixel is selected. The method also includes determining a difference between the value associated with the particular pixel in the set and each value associated with the other pixels in the set, and also determining that all of the determined differences are less than or equal to the quantization step size. In response, a filtered value for the particular pixel in the set is generated based at least on some of the pixels in the set in addition to the particular pixel.
