Abstract
페이드 기능을 갖춘 영상기기에 있어서, 페이드 시간을 사운드 레벨에 따라 변하게 한것으로 사운드 입력을 디지탈로 변환시켜 사운드 레벨을 표시시키는 사운드 레벨 메터(10)를 구비하고 상기 사운드 레벨 메터(10)의 디지탈 출력을 아나로그 전압으로 변환시켜 가산시키는 가산기(15)를 구비하며 상기 가산기(15)의 출력을 신호처리 IC(5)에 선택적으로 인가시키는 선택키(SW2)를 구비하여 페이드 기능을 증진시키도록 한것이다.A video apparatus having a fade function, comprising: a sound level meter (10) for converting a sound input into digital and displaying a sound level by changing a fade time according to a sound level, and outputting the digital output of the sound level meter (10). An adder 15 for converting and adding an analog voltage, and a select key SW2 for selectively applying the output of the adder 15 to the signal processing IC 5 to enhance the fade function. .
