Video Rendering



1  Abstract

 Video rendering, the process of generating device-dependent pixel data
from device-independent sampled image data, is key to image quality. System
components include scaling, color adjustment, quantization, and color space
conversion. This paper emphasizes methods that yield high image quality,
are fast, and yet are simple and inexpensive to implement. Particular
attention is placed on the derivation and analysis of new multilevel
dithering schemes. While permitting smaller frame buffers, dithering
also provides faster transport of the processed image to the display-a
key benefit for the massive pixel rates associated with full-motion video.
