摘要
A system and method that detects when pixels from one color space would exceed the range of a second color space, and restrict the range of the pixels without distorting their brightness, while preserving their color. The method may provide the ability to restrict the range of pixels in the first color space that may ordinarily transform to “illegal” values with erroneous brightness in the second color space, to a sub-space containing the entire second color space, while preserving the brightness of the pixels. The parameters used to define the sub-space may be programmable. The first color space may be YCrCb and the second color space may be RGB.
