METHOD AND SYSTEM FOR LUMINANCE PRESERVING COLOR CONVERSION FROM YUV TO RGB

摘要

This invention presents a YUV to RGB conversion method which preserves high precision of luminance information in an original YUV image signal when converting it to RGB signal. The method can be used to convert the original YUV signal to arbitrary quantization levels in RGB space. In addition, this invention presents methods of pre-quantization and re-quantization as to compensate conventional YUV to RGB color conversion.
