IMAGE PROCESSING APPARATUS, NOISE ELIMINATION METHOD, AND NOISE ELIMINATION PROGRAM

PROBLEM TO BE SOLVED: To provide an image processing apparatus, a noise elimination method, and a noise elimination program capable of properly eliminating noise in response to the motion of an image. SOLUTION: The image processing apparatus 100(1) includes: an image synchronization section 13 for synchronizing a frame image from an image input section 11 with a frame image from a frame storage section 12; a two-dimensional noise elimination section 14 for carrying out the elimination of the noise of the frame image by a two-dimensional noise elimination method; a motion detection section 15 for detecting the motion of the frame image; a frame circulation coefficient decision section 16 for deciding a frame circulation coefficient; a three-dimensional noise elimination section 17 for carrying out the elimination of the noise of the frame image by a three-dimensional noise elimination method; a composite ratio decision section 18 for deciding a composite ratio between a two-dimensional image eliminated image and a three-dimensional noise eliminated image; and a two-dimensional/three-dimensional composite section 19 for composing the two-dimensional image eliminated noise with the three-dimensional noise eliminated image.
