Interfacing analog camera

[Mike]

Is it possible to make this thru picmicro ?.
With additional hardware.

It's standard NTSC/PAL analog camera.

Thank you

I don't want to say "It can't be done", because people are incredibly ingenious. But think of it this way: the data in a single TV line takes 53 usec to transmit. If you had 250 pixels (and that's not much of a picture) in the line, you'd need to digitize the data at about 5 pixels per usec, which is way faster than a PIC can do it. And you'd need a place to store your results, and then there are hundreds of lines to deal with--and the PIC has limited ability to do math operations in any reasonable time. And that's assuming no colors to fool around with!

Maybe if you had a very simple black and white image--a black block against a white background, so you could use a comparator instead of an A/D--then you might do something. But I'm skeptical.

These cameras look interesting. I've never used them, but they seem to be designed with the idea of both gathering the data, and processing it.
