Abstract

본 발명은 도우밍 및 화이트 번짐을 제거하기에 적당하도록 한 영상기기의 도우밍 방지장치에 관한 것으로, 종래에는 명암 과다시 영상에 도우밍 및 화이트 번짐이 발생하였으나, 본 발명에서는 영상신호 발생부(2)의 명암 양이 과대할 경우 영상 처리부(1)의 명암이 작아지도록 하므로써 명암을 항상 안정하게 유지하므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to an anti-doming device of an imaging apparatus suitable for removing the doubling and white bleeding. In the past, the doubling and white bleeding occurred in the image with excessive contrast, but in the present invention, the image signal generator ( If the contrast of 2) is excessive, the contrast can be improved because the contrast is always kept stable by making the contrast of the image processor 1 small.
