More Information
Summary:An image processing apparatus includes: a noise-removed image generation unit which, on the basis of an input image and a reduced image obtained by reducing the input image at predetermined magnification, generates a noise-removed image with noise in the input image removed; and a corrected image generation unit which generates, from the noise-removed image, a high-frequency component image primarily having a frequency component of the noise-removed image in the same band as a frequency component to be removed by band limitation in the reduction at the predetermined magnification and generates an edge-corrected image on the basis of the noise-removed image and the high-frequency component image.
