Bit-depth extension with models of equivalent input visual noise |
摘要 |
A method for extending bit-depth of display systems. The method includes creating pseudo-random noise from human visual system noise. When applied to the image data, the noise causes spatiotemporal dithering. The pseudo-random noise is combined with image data, producing noise-compensated image data. The noise-compensated image data is them quantized. |
