Hi Dave, Cool, thanks, I'll have a look at the circuit and code to see if I can get some ideas. Looks similar to the CMUcam (based around a fast PIC equivalent). Colour thresholding just isnt up to anything more interesting than following an orange ball round the lab :) One of the advantages of very simple processing like that is that a small micro can do it on the fly as the pixels come in. I want to do optic flow, so I need to buffer a couple of frames in the gumstix memory. George.
