domains some embodiments of the present invention are summarized in the block diagram shown in fig8 wherein a high resolution image such as rgb high resolution image 70 is modified unlike some known methods the process is not carried out solely in the rgb domain the ycrcb color domain may also be used wherein the luminance and the chromatic components red green and blue yellow are separated other domains that are approximations to the visual systems opponent color channels will also work examples include cielab yuv and y r y b y since we need the luminance component for the contrast it is typically not disturbed however the chromatic components are subjected to modification that leads to attenuation of low chromatic frequencies eventually yielding a better sub pixel sampled image that has fewer visible chromatic artifacts embodiments of the present invention may be used to modify images which have been pre filtered or which exist in a format or condition which does not require initial low pass filtering these particular embodiments may bypass 71 the rgb separation and low pass filtering steps and begin by processing an image 70 at sub pixel sampling 86 as the block diagram shows the initial high resolution image 70 in rgb format is separated into r 72 g 74 and b 76 data these individual frames may then be passed through optional low pass filters lpf 78 80 amp 82 that in some embodiments may have a cut off frequency of about 0 5 cycles pixel i e a display pixel this filtering essentially removes any high frequency chromatic components and also makes the image band limited different filters may be used for different color.
