ABSTRACT:
A display system provides temporal stochastic dithering to image data for storage in a frame buffer for display. Stochastic dithering is used to reduce the size of the frame buffer and the complexity of the drive circuitry that is used to display an image in accordance with the image data. The bit depth of the frame buffer is reduced by spatially dithering image data for the image data before the image data is written into the frame buffer. Additionally, the displayed image is temporally dithered by using a different dither pattern for successive frames. Uncorrelated stochastic dither patterns are used to minimize detection of the dither patterns within the displayed image.
