An image processing method for improving image quality by appropriately detecting ringing artifacts and reducing only the detected ringing artifacts, is an image processing method which includes: selecting, from among a plurality of pixels included in an input image, a candidate for a noise pixel included in the ringing artifacts, using luminance values of the plurality of pixels; judging whether or not the candidate selected in the selecting is the noise pixel based on whether or not a chrominance value of the candidate is included in a chrominance range corresponding to a comparison target region which is a part of the input image; and filtering the noise pixel which has been judged in the judging.
