video processor using DE2

Hi all, i would like to implement a video processor that can process HD video data from stereo cameras. After watching this video:

Easily Support WDR CMOS Image Sensor Processing with Low-Cost FPGAs

I got a few questions for the DE2 kit. Does DE2 provide HD image process? or i need to buy a HDMI card to do the process? Like CMOS sensor-->adapter card--> DE2 board --> HDMI card-->display

The DE2 kit is provided but the others (CMOS sensor,adapter card, HDMI card) need to buy them by myself. And i just got 200 pounds budget for those ... The HD CMOS camera seems like quite expensive.. Is there any suggestions for me to finish buy those stuff?
