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.
