<P>PROBLEM TO BE SOLVED: To obtain a dynamic image with reduced shake while removing a noise. <P>SOLUTION: An image processing device removing a noise by composing a base image and at least one reference image, has: a motion vector calculation part (101) calculating a motion vector between the base image and the reference image; a motion compensation part (102) compensating the motion so as to align the reference image with the base image based on the motion vector; a contrast calculation part (103) calculating a contrast value of a target pixel of the base image from the base image or the reference image; a composition ratio calculation part (105) calculating a composition ratio between the target pixel of the base image and a corresponding pixel of the motion-compensated reference image which corresponds to the target pixel, depending on the contrast value of the target pixel; and a composition part (106) composing the target pixel of the base image and the corresponding pixel of the reference image based on the composition ratio. <P>COPYRIGHT: (C)2012,JPO&INPIT |
