Real-time color gamut mapping method for digital TV display quality enhancement

A novel real-time color gamut mapping method is described. The color gamut mapping method that is used for enhancing the color reproduction quality between PC monitor ad printer devices is adopted for digital TV display quality enhancement. The high definition digital TV display devices operate at the clock speed of around 70 MH to 150 MHz and permit several nano seconds for real-time color gamut mapping. Thus, the concept of three-dimensional reduced resolution look-up table is introduced for real-time processing. The required hardware can be greatly reduced by look-up table resolution adjustment. The proposed hardware architecture is successfully implemented in FPGA and ASIC and also successfully adopted in digital TV display quality enhancement purposes.
