Abstract
A method for detecting color burst signal amplitude of a composite color image signal for use in an automatic color control circuit includes the steps of separating the burst signal loaded on the chrominance signal into first and second chrominance reference signals having a predetermined phase difference with respect to each other using a carrier signal having an arbitrary burst signal, detecting the squared components of the separated first and second chrominance reference signals respectively, and outputting the amplitude value of the burst signal using a composite signal of the squared components of the detected first and second chrominance reference signals. An apparatus using this method can detect the level of the burst signal regardless of the phase difference between the burst signal and the demodulated carrier.
