Video and Image Processing for Camera

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.

These functions allow you to fully integrate common video functions with video interfaces,

processors, and external memory controllers. The example design uses an Altera Cyclone® IV E

EP4CE115F29 featured tPad board.

A video source is input through the CMOS sensor on tPad which generates a digital output in RGB

format. A number of common video functions are performed on this input stream in the FPGA.

These functions include clipping, chroma resampling, motion adaptive deinterlacing, color space

conversion, picture-in-picture mixing, and polyphase scaling.
