Abstract
1.청구 범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs
영상신호 처리장치의 테이프 주행속도 검출분야Tape running speed detection field of image signal processing device
2.발명이 해결하려고 하는 기술적 과제2. Technical problem that the invention tries to solve
간단한 구성을 가지면서도 에러없이 정확하게 테이프 주행속도를 검출하는 회로 및 방법을 제공함에 있다.The present invention provides a circuit and a method for detecting a tape traveling speed accurately with no errors while having a simple configuration.
3.발명의 해결방법의 요지3. Summary of the solution of the invention
개선된 영상신호 처리장치의 테이프 주행속도 검출회로는 헤드스위칭 펄스에 동기된 조그 펄스를 생성하기 위한 수단과;상기 수단에 연결되며,상기 헤드스위칭 펄스의 구간동안에 인가되는 조그펄스의 갯수를 카운팅하고 그 카운팅 값과 미리 설정된 테이프 재생 모드값을 비교하여 테이프의 주행속도르 검출 및 제어하는 수단을 가짐을 특징으로 한다.The tape running speed detection circuit of the improved image signal processing apparatus includes means for generating a jog pulse synchronized with the head switching pulse; and connected to the means, counting the number of jog pulses applied during the period of the head switching pulse. And a means for detecting and controlling the running speed of the tape by comparing the counting value with a preset tape reproduction mode value.
