Abstract

A look-up table algorithm is described for enhancing the luminance resolution at the expense of the colour resolution in digital displays of colour images. For colour displays with a look-up table resolution of 8 bits/gun, the algorithm provides a luminance resolution of 11-12 bits without loss of spatial or temporal resolution. This improvement can reduce the minimum luminance step in the mid-luminance range from 1.5% to > 0.2% with no additional hardware.

摘要

本文描述了一种查找表算法，该算法以牺牲彩色图像数字显示器中的颜色分辨率为代价来提高亮度分辨率。对于具有8位/色枪查找表分辨率的彩色显示器，该算法可提供11至12位的亮度分辨率，而不会损失空间或时间分辨率。这种改进可以在不增加额外硬件的情况下，将中等亮度范围内的最小亮度步长从1.5%降低到大于0.2%。
