| 1. A method for producing an image from image data comprising:
accessing stored image data from a memory, the image data defining an input image acquired using an imaging system;
determining a pixel sampling rate for the image data using an image processing circuit;
determining a desired sampling rate using the image processing circuit, wherein the desired sampling rate is determined based
at least partially on a point-spread function of the imaging system or the frequency content of the image data;
comparing the pixel sampling rate to the desired sampling rate using the image processing circuit; and
based upon the comparison, using the image processing circuit to process the image data by shrinking the input image if the
pixel sampling rate is greater than the desired sampling rate.
