According to the structure and characteristics of the three-dimensional spectrum of TV signal, the three-dimensional bright color separation technology adopted in the improved definition TV is analyzed mathematically. The filtering characteristics of the three-dimensional bright color separation are obtained by theoretical results and numerical calculation. According to the principle of motion detection and vertical correlation detection, an adaptive three-dimensional bright color separation method based on real-time dynamic detection is proposed. By real-time dynamic detection of the image, the bright color separation can be automatically maintained in a good state and the image weight is improved Now quality
