Abstract
In a system and method of reducing noise, an image sensor with a color filter array (CFA) outputs raw data, and a noise reduction device corrects the raw data according to distances between an original current pixel and neighboring same-color pixels in a process mask, thereby generating a new current pixel so as to output corrected raw data. A color interpolation device couples to receive the corrected raw data to result in full-color data.
