ABSTRACT:
A method and system of eliminating color noises caused by an interpolation, which performs an interpolation on a Bayer image obtained by an image sensor to restore red, green and blue colors of each pixel. Interpolated image is converted into a chromatic domain in order to rapidly use chroma pixel values of a pixel previously processed to eliminate color noises to update the original chroma pixel values in a median filter with 3×3 area of 2D, thereby increasing the color noise filtering capability of the median filter, and a low-pass filter is used to further eliminate the uneven effect of clustered color noises filtered out by the median filter.
