Zusammenfassung:Provided is a technique for reducing image noise while preventing artifacts such as, for example, color blurring at color edges. An image processing method includes a real space filter processing step (S10) and a color space filter processing step (S20). In the real space filter processing step (S10), filter processing based on a distance in a real space is performed. In the color space filter processing step (S20), filter processing based on a distance in the real space is performed. The real space filter processing step (S10) is based on an edge preserving filter processing, and the pixel data of an attention pixel used in the color space filter processing step (S20) is the pixel data calculated in the real space filter processing step (S10).
