Abstract
본 발명은 고품위의 뮤즈신호를 현행 TV(NTSC)신호로 변환하기 위한MUSE/NTSC컨버터에 있어서 음극선관에 인가되는 입력된 뮤즈신호에서 만들어진 화상의 휘도, 색상 및 색 포화도등이 전압 대 빛 빛출력간의 비직선성으로 인해 충실히 재현되지 못하는 점을 비직선 증폭회로인 감마보정회로를 이용하여 화상특성을 보정하기 위한 것이다.According to the present invention, the luminance, color, and color saturation of an image produced from an input muse signal applied to a cathode ray tube in a MUSE / NTSC converter for converting a high-quality muse signal into a current TV (NTSC) signal are outputted as voltage versus light. The fact that the nonlinearity of the liver is not faithfully reproduced is to correct image characteristics using a gamma correction circuit which is a nonlinear amplification circuit.
