Abstract

본 발명은 피디피(POP) 티브이의 노이즈 제거장치에 관한 것으로, 현재라인의 영상데이타와 제1라인지연부와 제2라인지연부를 통해 설정된 소정시간 동안 각각 지연된 영상데이타가 마스킹부를 통해 3 ×3 블록으로 마스킹되고, 메디안 필터링부를 통해 3 ×3 블록의 각 영상데이타 중에 중간값이 영상처리부를 통해 디스플레이 가능한 영상데이타로 신호처리된 다음 PDP 패널로 디스플레이되므로써, 스파크 노이즈가 메디안 필터링부를 통해 제거되므로, PDP 티브이로 보다 선명한 화질의 영상을 디스플레이 할 수 있도록 한 것이다.[0001] The present invention relates to a noise cancellation apparatus for a portable digital video (POP) TV, in which video data delayed for a predetermined time, which is set through video data of a current line and a first line delay unit and a second line delay unit, The intermediate value of each image data of the 3x3 block is subjected to signal processing with image data that can be displayed through the image processing unit and then displayed on the PDP panel through the median filtering unit so that the spark noise is removed through the median filtering unit, So that it is possible to display images of clearer image quality on a TV.
