The present invention provides a noise point suppression method for filtering noise points in a source image through a reference image, wherein, the arrangement mode of each pixel of the source image and the reference image accords with a Bell Figure color arrangement role. In the method, a first quasi image which corresponds with the source image and a second quasi image that corresponds with the reference image are generated. Total-domain movement vector between the first quasi image and the second quasi image is calculated. Dynamic compensation processing is performed on the reference image according to the total-domain movement vector for obtaining a plurality of dynamic compensation results. Furthermore the dynamic compensation results are used for performing time superposing processing on the source image for generating a first-stage noise point suppression image. Then spatial noise point elimination processing is performed on the first-stage noise point suppression image for generating second-stage noise point suppressing image.
