A method for reducing color noises of a chrominance signal includes the following steps: receiving the chrominance signal; sampling the chrominance signal to generate a plurality of chrominance samples; determining a phase-rotation level between a specific chrominance sample and the chrominance samples; calculating an average value of the chrominance samples; and selectively outputting the average value or the chrominance information of the specific chrominance sample as an output chrominance information to represent the color information of the specific chrominance sample according to the phase-rotation level.
