ABSTRACT:
Embodiments of the present invention provide systems and methods for converting a high-resolution image to a lower-resolution image with reduced visible errors. These systems and methods comprise a sub-pixel sampling simulation performed on a high-resolution image to determine an error introduced into the high-resolution image as a result of sub-pixel sampling. This error may be isolated from the high-resolution image to create an error image which may be modified with a visual model to remove invisible errors thereby creating a visible error image. The visual error image may then be combined 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 when the sub-pixel sampling occurs.
