Test Pattern Generator using a Digital Camera
For the purposes of setting up CCTV surveillance systems I needed a small, mobile, battery-powered video test-card picture generator. In my work as a video technology developer, I use several di erent types of test signal generators but they are neither small nor battery powered. I started to think about how I could build a portable generator out of a combination of components such as a CPLD, RAM and DAC.
