Abstract
디지탈 영상처리장치에 있어서 영상신호에 포함된 잡음을 저감시켜주는 장치가 개시된다. 디지탈 순회형 3차원 잡음저감장치에 있어서 코아링회로의 코아링특성을 입력되는 영상신호의 동벡터량에 따라 적응적으로 변화시켜 입력되는 영상신호의 특성에 관계없이 균일한 화질을 갖는 잡음저감된 영상신호를 제공한다.Disclosed is a device for reducing noise included in a video signal in a digital image processing apparatus. In the digital cyclic 3D noise reduction device, the coreing characteristic of the corering circuit is adaptively changed according to the amount of dynamic vector of the input image signal, so that the noise-reduced image has a uniform image quality regardless of the characteristics of the input image signal. Provide a signal.
