发明名称 Spatio-temporal color dithering techniques
摘要 Systems and methods are disclosed to enable the creation and the display of spatio-temporal dithered images. Embodiments include techniques that use color-shifting and luminance. In one embodiment, adjacent pixels (52, 54, 56, 58) are color-shifted with respect to each other and the color values of the adjacent pixels (52, 54, 56, 58) are temporally alternated with color values of pixels in the group. In another embodiment, the luminance of group (84) of adjacent pixels is determined and the luminance of the group (84) is made more homogenous spatially and temporally by distributing color variations over a larger number of pixels so as to reduce the luminance difference between the pixel with the least luminance and the pixel with the greatest luminance. Individual color components (e.g., red, green, blue) may also be separated and used so that the color-shifts associated with each color component may be simultaneously present in different pixels.
