ABSTRACT:
The invention discloses an image processing apparatus and method. The method of the invention first splits the image into a green color plane, a red color plane and a blue color plane. Afterward, each one of the green color plane, the red color plane and the blue color plane is sequentially masked by a working window, such that each of the pixels on the one color plane is sequentially located at the center of the working window and referred to as a central pixel. Then, the pixels other than the central pixel in the working window are classified into edge pixels and non-edge pixels. Finally, a filtered central pixel is calculated according to a formula, and the central pixel is replaced with the filtered central pixel, whereby the noises of the image remained in the CFA domain are suppressed.
