Conventional coding of digital color images is done in a luminance-chrominance domain, and the chrominance components are subsampled in a fixed ratio with respect to the luminance. We propose an adaptive method of subsampling the chrominance components that improves the quality vs. sample rate trade-off. In applications such as compositing color graphics images, the advantage of using the adaptive method as against the conventional method is demonstrated.<>
