Video noise reduction apparatus and method

The present invention is stored in that buffer register, the buffer register the separation of the video signal of the acquired n * n regions from the image sensor into a brightness component and a saturation component to store the pixel values ​​on the image noise removing device and the image noise reduction method n * n region the contour region, it includes textured region, the image analysis section for classifying a flat region, and a noise reducing unit for reducing the noise of the image to design a noise reduction filter in accordance with the characteristics of the classification region. Contour region, the texture region, the flat region, and the buffer register, the noise removing filter
