A method for reducing the visibility of sub-Nyquist aliasing artifacts in an image, where the image is produced in a scene-to-output imaging system that is represented by a modulation transfer function, includes the steps of: (a) providing a source image signal as an input image having sub-Nyquist aliasing artifacts, where image content is represented by an image frequency response and a frequency response amplitude; (b) determining a preferred aliasing ratio by utilizing an aliasing equation that depends on image frequency and pixel count of the imaging system; and (c) adjusting the frequency response amplitude of the image signal for image frequencies corresponding to the preferred aliasing ratio so as to correspondingly adjust the modulation transfer function of the scene to output system to maintain the preferred aliasing ratio while reducing the frequency response amplitude, thereby providing an image with reduced visibility artifacts.
