Description
Color space conversion is often necessary when transferring data between devices that use different color space models. For example, to transfer a television image to a digital computer image the data must undergo Y'CrCb to R'G'B' conversion. The color space convertor (CSC) is a general core that converts from one color space to another. The CSC core converts gamma-corrected computer RGB digital values (i.e., each component is in the range of [0,255]) of each pixel to YCrCb video components."
