Abstract: PURPOSE: An image processing method and device are provided to generate an image which color noise is excellent and maintain an edge component in general environment, low level light environment, and high sensitivity environment. CONSTITUTION: An RGB input image single is converted into a YCbCr input image signal(800). The YCbCr input image signal is divided into a luminance signal and a chrominance signal(810). After noise is eliminated from the divided luminance signal, a luminance signal existed in the noise is restored(820). Noise is eliminated from the chrominance signal(830). An image, which final noise is eliminated, is outputted by combining the luminance signal with the chrominance signal which the final noise is eliminated(840).

An image processing apparatus includes a determination module(110), an intensity mapping module(120) and an image synthesizing module(130). The determination module(110) determines if a contrast improvement process is performed with respect to an input image. The intensity mapping module(120) creates the input image into a plurality of images having different exposure time by using intensity mapping if the execution of the contrast improvement process is determined. The image synthesizing module(130) synthesizes the created images with each other.
