Raster-order pixel dithering |
摘要 |
Stochastic dithering may be used to reduce the size of the frame buffer and the complexity of the D/A Converters (DACs) in the drive circuitry that are used in a video display system. Hardware for stochastic dithering can be simplified when pixel data is presented in raster order. The hardware adds algebraic noise to the image to be dithered, and thresholds the result.
