Hello,
Could you give me some guides how to process image from camera. Suppose, I need to found red ball on white floor.
So, I need:
I wil be happy for any inormation. Thanks.
Sorry this is way outside the scope of an arduino. There is not enough speed but more importantly memory to do anything approaching this. Try another platform.
- Connect camera to Arduino
Oops. Fallen at the first.
Not impossible, but you might want to consider your timescales.
Thanks for quick reply.
I’ll implement another idea 
And that'll be able to discriminate a red ball from, say, a blue ball?

Well I was going with this situation...
Perhaps a white ball on a dark floor if that can't be made to work so well. Or even a glowing ball - adding some LEDs to a ping pong ball wouldn't be too bad.
AWOL: And that'll be able to discriminate a red ball from, say, a blue ball?
Possibly, if you can split the RGB channels. Whether the Arduino's fast enough to do it in a way that's useful (or has enough memory to handle it) is another matter. :)

There is no RGB in a composite video signal - you'd need a NTSC/PAL/SECAM/whatever decoder too.
Good point, it'd just be looking at luma levels (long time since I used a composite video connection, can you tell?). Probably no colour recognition then.
That board does video overlay, the only thing that arduino is doing is sending some text. There is not even enough ram to save an 320x240 black and white frame.

It does a lot more than video overlay.
Capture low-res video image frames for display or video processing. Give your Arduino the gift of sight!
