APPARATUS FOR REMOVING AN IMAGE NOISE AND A METHOD OF THEREOF, PARTICULARLY FOR DISPLAYING HIGH QUALITY IMAGE BY EFFICIENTLY REMOVING NOISE COMPONENTS

摘要

PURPOSE: An apparatus for removing an image noise and a method of thereof are provided to efficiently subdivide image characteristics by classifying an image region.;CONSTITUTION: A buffer register(110) classifies an acquired image signal of an acquired n*n region of an image sensor into luminance components and saturation components, and stores the image signal as a pixel value. An image analysis unit(120) classifies the stored n*n region into an outline region, a texture region and a flat region. According the characteristics of the divided region, a noise reduction unit(130) reduce the noises of the image by designing noise cancellation filters(131-134).;COPYRIGHT KIPO 2011
