Abstract
An apparatus, process, and computer program product provide an improvement to downscaling techniques for image processing. Embodiments of the downscale processes may be applied to images rendered on printed documents. Aspects of the downscaling processes provide quality, discernible rendered images while being efficient with computing resources. Exemplary embodiments carryover binary bit data from adjacent regions into an application region being downscaled for determination of the downscale output. Depending on the downscale output value for the application region, bits from the application region may be carried over to adjacent regions and used in determining whether those regions, when processed will have an “ON” or “OFF value when downscaled.
