ABSTRACT:
A spatial image processing method for noise elimination, including the steps of subjecting an image signal representing a color image and including a density data signal component and a color data signal component to processing for extracting color data for each picture element of the image, discriminating regions of the color image exhibiting a specific color on the basis of the extracted color data, and subjecting the image signal to spatial image processing for elimination of noise under different processing conditions for regions of the image exhibiting the specific color and the remaining regions of the image not exhibiting the specific color.
