Device for removing noise on image using cross-kernel type median filter and method therefor

摘要

A device for removing a noise on an image using a cross-kernel type median filter includes a target pixel determination unit configured to determine whether a target pixel is a noise or not; a peripheral pixel determination unit configured to determine degrees of the noise on a peripheral pixel information of a peripheral pixel of the target pixel; and a noise removing unit configured to remove the noise of the target pixel and corrects the image by applying a cross-kernel type median filter based on the peripheral pixel information.
