Claim One:
1. An image processing device comprising: an image acquiring device that acquires a plurality of images obtained by capturing a same subject plural times; a memory; and a processor, the processor being configured to select, as a reference image, one image of the plurality of images; generate for a non-reference image that was not selected a transformed image that is transformed by making a position of an image of a same subject correspond to the reference image; perform noise-reduction processing on the reference image and generate a noise reduced image; set a weighting coefficient of the reference image with respect to the transformed image such that, the greater an absolute value of a first difference in pixel values of corresponding pixels of the reference image and the non-reference image, the greater the weighting coefficient, and generate an intermediate composite image by carrying out combining processing of the reference image and the transformed image on the basis of the set weighting coefficient per pixel; and set a weighting coefficient of the noise reduced image with respect to the intermediate composite image such that, the greater an absolute value of a second difference in pixel values of corresponding pixels of the reference image and the intermediate composite image, the smaller the weighting coefficient, and generate a final image by carrying out combining processing of the intermediate composite image and the noise reduced image on the basis of the set weighting coefficient per pixel.
