Abstract

본 발명은 비디오 카메라의 윤곽보정장치에 관한 것으로, 종래에는 감마 보정된 신호로부터 휘도처리계에서 수평, 수직 윤곽 보정후 이를 합산하여 윤곽억업부에서 휘도신호에 따라 고휘도 성분을 억압함으로써, 윤곽 보정을 행하는데, 이는 휘도성분에 따라 윤곽 보정이 일정하기 때문에 사람의 얼굴등을 줌업했는데 너무 섬세하게 나타나 추하게 보이는 경우가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contour correction apparatus for a video camera. Conventionally, contour correction is performed by suppressing a high luminance component according to a luminance signal by adding the horizontal and vertical contour corrections in a luminance processing system and adding them from a gamma corrected signal. This is done by zooming up the face of a person because the contour correction is constant according to the luminance component.

본 발명은 이를 개선하고자 칼라처리계에서 검출되는 R-Y 색차 신호를 버퍼를 통해 추출한 후 이득제어부를 통해 레벨 조절하여 상기 윤곽억압부의 윤곽보정을 제어하도록 하여 사람의 얼굴등을 윤곽보정시에 그 윤곽 보정을 저게 함으로써 부드러운 얼굴화면을 얻기 위한 것이다.To improve this, the present invention extracts the RY color difference signal detected by the color processing system through a buffer, and then adjusts the level through the gain control unit to control the contour correction of the contour suppressor to correct the contour of the face of the person. To get a smooth face.

Claims (1)

휘도처리계에서 수평, 수직윤곽보정부(5), (6)를 통해 수평, 수직윤곽 보정하여 이를 합한 후, 윤곽업압부(8)를 통해 고휘도 성분을 억압하여 윤곽보정을 행하도록 하는 윤곽보정장치가 있어서, 카랄처리계의R-Y 색차신호 이득제어부(11)로부터 R-Y 색차신호 이득제어부(11)로부터 R-Y 색차신호를 추출하는 버퍼(16)와, 그 버퍼(16)의 출력을 레벨 조절하여 상기 윤곽억압부(8)의 윤곽보정 제어신호로 인가하는 이득제어부(17)를 포함시켜 구성된 것을 특징으로 하는 비디오 카메라의 윤곽보정장치.In the luminance processing system, horizontal and vertical contour corrections (5) and (6) are added to the horizontal and vertical contour corrections, and the contour correction is performed by suppressing the high luminance component through the contour up pressure unit (8). In the apparatus, a buffer 16 for extracting an RY color difference signal from the RY color difference signal gain control unit 11 from the RY color difference signal gain control unit 11 of the karal processing system, and the output of the buffer 16 are adjusted to the above level. And a gain control unit (17) for applying the contour correction control signal of the contour suppressing unit (8). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
