PROBLEM TO BE SOLVED: To provide an image processing device, a noise eliminating method and a noise eliminating filter enabling area extraction of a moving object with high accuracy, in image processing for extracting the moving object area, by rejecting unnecessary varied pixels from a binarized image obtained by extracting the varied pixels from the difference between a past image and a present image. SOLUTION: A diffusion filter 154 successively sets pixels of interest to each pixel excluding the outermost circumference of the above differential binary image. When there is a varied pixel in a pixel in the oblique direction adjacent to each set pixel of interest, diffusion filter processing is executed by using the pixel of interest as the varied pixel. By combining the diffusion filter 154 with an contraction filter 155, a noise eliminating filter for differential binary images is configured. COPYRIGHT: (C)2008,JPO&INPIT |
