Title: IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING PROGRAM
Abstract:
An image processing apparatus 10 comprises: a first generation unit 11 that generates a plurality of lower-resolution images having different row-direction resolutions by changing a resolution in a row direction of an image to be processed to a plurality of lower resolutions; a second generation unit 12 that generates a differential image by taking a difference between two of the plurality of lower-resolution images; and a calculation unit 13 that calculates a correction amount for the pixel values of a predetermined column of the image to be processed by use of a statistical quantity of the pixel values of a predetermined column of the differential image.
