Color Space Converters (CSC) are used in video and image display systems including televisions, computer monitors, color printers, video telephony and surveillance systems. CSCs are also used in many video/image compression and processing applications, and in the implementation of NTSC/PAL/SECAM television standards, JPEG and MPEG systems. Color space conversion is required when transferring data between devices that use different color space models. For example, RGB to YCbCr color space conversion is required when displaying a computer image on a television. Similarly YCbCr to RGB color space conversion is required when displaying television movies on the computer monitor. As a color can be represented completely using three dimensions, a color space is a three dimensional space. Color space conversion is a one-to-one mapping from one color space to another color space.
