The Video and Image Processing (VIP) for Camera Example Design demonstrates dynamic scaling
and clipping of a standard definition video stream in RGB format and picture-in-picture mixing
with a background layer. The video stream is output in high definition resolution (800× 600) on the
HSMC LTC daughter card (part of the tPad).
The example design demonstrates a framework for rapid development of video and image
processing systems using the parameterizable MegaCore® functions that are available in the Video
and Image Processing Suite. Available functions are listed in Table 4 2. This demonstration needs
the Quartus II license file includes the VIP suite feature.
