PROBLEM TO BE SOLVED: To provide an image processing method, an image processing apparatus and a computer readable/writable recording medium for suppressing noise in a digital image without causing an unpleasant unevenness due to the noise or an unnatural artifact or the like. SOLUTION: Smoothing and edge detection are applied to original image data, the edge and noise intermingled image data of an object are found from the obtained smoothed image data, a noise weighting coefficient is obtained from edge emphasis data obtained by the edge detection, noise data are obtained from the weighting coefficient and the intermingled image data, a noise suppression distribution function denoting the spread of noise suppression is set, convolution integral is applied to this function and the noise data to calculate the noise suppression distribution, a noise suppression component is obtained by multiplying the noise suppression distribution by the noise data and the component is magnified and subtracted from the original image to obtain processed image data so as to solve the problems above. |
