1. A method for converting a high-resolution image to a lower-resolution image with reduced visible errors, said method comprising the acts of: performing a sub-pixel sampling simulation on said high-resolution image to determine an error introduced into said high-resolution image as a result of sub-pixel sampling; isolating said error from said high-resolution image thereby creating an error image; modifying said error image with a visual model to remove invisible errors thereby creating a visible error image; and combining said visible error image with said high-resolution image to create a compensated image that will substantially cancel the error introduced as a result of subsequent sub-pixel sampling.
