I am actually at the very beginning of figuring out just exactly how to take a snapshot because I was working with sobel/color detection with video earlier. I'm just starting out with working with the registers, and also trying to figure out the sdram. We're working on a image recognition for nios ii to interpret, and right now i'm stuck on exactly how to approach the whole idea of taking a snapshot. I haven't tried coming up with code myself as that seems to be a daunting task, but rather editing the video code to make the camera take a snapshot. I see from you that its pretty hard? Would I be able to take a look at your code for the GRR?
