Abstract

In order to provide an image processing device and the like making it possible to generate a target image in which edges of a structure are upheld and from which streaking artifacts are removed a computation device determines the shape of a non linear function on the basis of feature amounts of an original image and a smoothed image (S101). Next the computation device calculates a condition coefficient of the original image and the smoothed image by using the non linear function for which the shape was determined in S101 (S102). Next the computation device uses the condition coefficients calculated in S102 to calculate a weighting coefficient for each of the pixels of the original image and the smoothed image (S103). Next the computation device adds weighting to the original image and the smoothed image to generate the target image (S104).
