Abstract

Images displayed by projection systems can have geometric distortions. These distortions can be compensated by electronic correction, also called image warping. When the image that shall be displayed is composed from several input sources, the different image layers have to be corrected independently from each other to achieve optimal image quality. A VLSI architecture for independent electronic correction of multiple image layer is proposed.
