摘要-在理论上使用CIELAB和CIECAM 02颜色外观模型，并通过使用真实的图像进行心理物理测试，对Texas Instrument DLP™数字投影仪技术中实施的白色通道增强效果进行了评估。理论和测试结果都证实了作为添加的白色通道的结果，在色度和色彩度方面的感知色域的压缩。因此，虽然该技术非常适合在亮度对比度很重要的会议室环境条件下查看图形和文本，但对于查看图像或在颜色很重要的家庭影院环境中，它必然不太理想。
Abstract— The effect of white‐channel enhancement as implemented in the Texas Instrument DLP™ digital projector technology is evaluated theoretically using both the CIELAB and the CIECAM02 color appearance models and experimentally through psychophysical testing using real images. Both theory and test results confirm a compression of perceptual gamut in both chroma and colorfulness as a result of the added white channel. Hence, while this technology is ideal for viewing graphics and text under ambient conference‐room conditions where lightness contrast is important, it is necessarily less than ideal for viewing images or in home‐theater environments where color is important.
