Patent ID: 8421815

Claim:
A method for generating a bit plane color sequence for a frame sequential color image display system, the method comprising: at a processing device, receiving an input data stream representing imaging data for display of a frame of an image during a frame display time, the data stream comprising successive groups of n bits of data for each of m component colors for each pixel of the image; wherein n is a positive integer greater or equal to four and m is a positive intger greater or equal to two; determining relative lengths of the frame display time needed for display of each of the respective m component colors, based on relative luminance available from an illumination source for display of that component color using weighted bit plane pulse width modulation based on n bits of data; for the one component color having a longest relative length, displaying that one component color of the image using a weighted bit plane sequence for each pixel with the pixel values for the bit planes determined by the n bits of data on a one-to-one correspondence with the n bits of data for that one component color for the pixels in the input data stream; and for at least one other component color having a relative length less than the longest relative length, displaying that at least one other component color of the image using a weighted bit plane sequence for each pixel with the pixel values for one or more bit planes determined by the n bits of data on a multiple pixel grouping-to-one correspondence with the n bits of data for that at least one other component color for designated ones of the pixels in the input data stream.
