Abstract

본 발명은 기존의 슈퍼 임포즈위에 임포즈하는 부분의 에지에 블랭킹 신호를 인가하여 입체적인 표현을 할 수 있는 캠코더의 에지 블랭킹 슈퍼 임포즈 시스템에 관한 것으로 기존의 마이컴(9)에서 출력되는 에지 블랭크 (Eb)와 캠코더 녹화시 메모리된 슈퍼 임포즈 블랭크(Sib)를 에스램(5)으로부터 입력받아 재생시 슈퍼 임포즈에 에지 블랭크 신호를 더해주는 에지 블랭크 공급부(11)를 포함하여 이룰 수 있다.The present invention relates to an edge blanking super impose system of a camcorder capable of three-dimensional expression by applying a blanking signal to an edge of a portion imposed on a conventional super impose. Eb) and an edge blank supply unit 11 which receives the superimposed blank Sib memorized during recording of the camcorder from the SRAM 5 and adds an edge blank signal to the superimpose during playback.
