IMPLEMENTING THE COLOR SPACE TRANSFORMATION ALGORITHM USING THE TMS320C2XX

The Texas Instruments (TIä) TMS320 family of digital signal processors (DSPs) is widely used for digital image processing. Color space transformation, one of the basic image processing algorithms, is used for digital still camera, color printer, color scanner, and other video product applications.

This application report describes how to implement the algorithm of transforming the image color space from (R, G, B) to (Y, U, V) using TMS320C2xx assembly language. With the information provided, users can implement other color space transformations, such as (Y, U, V) to (R, G, B), (R, G, B) to (Y, Cr, Cb), etc., by modifying the transformation coefficient matrix.
