Abstract

A system and method for processing image data to be displayed on a display device, where the display device requires more power to be driven to display image data comprising particular spatial frequencies in one dimension than to be driven to display image data comprising the particular spatial frequencies in a second dimension. The method includes receiving image data and filtering the received image data such that the image data at particular spatial frequencies in a first dimension are attenuated more than the image data at particular spatial frequencies in a second dimension.
