摘要： A color noise suppressing system, which has a converter, a saturation compute device, a maximum compute device, and a chroma suppressor. The converter converts a YUV image signal into an RGB image signal. The saturation compute device is connected to the converter for computing a saturation from the RGB image signal and converting the saturation into a first gain. The maximum compute device is connected to the converter for computing a maximum from the RGB image signal and converting the maximum into a second gain. The chroma suppressor is connected to the saturation compute device and the maximum compute device for performing chroma suppression on the YUV image signal according to the first and second gains.
