Abstract:
1. An image processing device comprising: a filtering unit comprising a plurality of filtering unit stages for filtering an input image; a plurality of band image signal generating units for generating a plurality of band image signals having different frequency bands from each other from an output image of the filtering unit; a noise reduction processing unit for performing a noise reduction process of reducing a noise component contained in the plurality of band image signals generated by the band image signal generating units; and a plurality of image synthesizing units for synthesizing the plurality of band image signals subjected to the noise reduction process; wherein the image processing device includes a first pixel expansion unit for performing a pixel expansion process of expanding pixels at an outer peripheral part of an image input to one of the plurality of filtering unit stages other than a first stage of the filtering unit, or an image output from one of the plurality of band image signal generating units.
