Abstract
An image processing apparatus includes a parameter setting unit which sets a noise reduction processing parameter for use in noise reduction processing for applying onto an original image signal including a plurality of color components; a correlation arithmetic processing unit which calculates coefficients of correlation between each of the color components in the original image signal; a parameter correcting unit which corrects the noise reduction processing parameter based on the coefficient of correlation; and a noise reducing unit which reduces noise in the original image signal using the corrected noise reduction processing parameter.
