Abstract

본 발명은 고스트 제거방법에 관한 것으로, 역필터를 통과한 GCR신호를 이용하여 잔류고스트 레벨을 측정하고, 이 결과로 역필터의 계수를 미세 조정하여 잔류 고스트를 완전히 제거할 수 있도록 한 것이다.The present invention relates to a ghost removal method, and to measure the residual ghost level using the GCR signal passed through the inverse filter, and as a result fine adjustment of the coefficient of the inverse filter to completely remove the residual ghost.

Claims (1)

고스트 제거장치에서 입력신호의 잡음이나 계산오차에 의해 완전히 제거되지 않은 잔류고스트를 제거하는 방법에 있어서, 고스트 제거장치의 역필터를 통과한 GCR 신호를 이용하여 잔류 고스트 레벨을 측정하는 단계와, 상기 단계 설정 결과로 역필터의 계수를 직접 미세 조정하여 잔류 고스트를 제거하는 단계로 이루어진 잔류 고스트 제거방법.A method for removing residual ghost that is not completely removed by noise or a calculation error of an input signal in a ghost eliminator, the method comprising: measuring a residual ghost level using a GCR signal passed through a reverse filter of the ghost eliminator; Residual ghost removal method comprising the step of removing the residual ghost by directly fine-tuning the coefficient of the reverse filter as a result of the step setting. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
