Abstract

Spatial image resizing is a very important issue for pixel oriented displays with variable input formats. A known example is a scaling factor of two for up-scaling from Standard Definition (SD) to High Definition (HD) format. We investigated an up-scaler for rational factors with nonlinear detail enhancement using principle of Priority Processing. Priority Processing can guarantee real time performance on programmable platforms even with limited resources. Our up-scaler adapts to the available hardware resources and depicts a good output quality for a wide range of scalability.
