camera brightness thresholding

Hi, I hope this is the right section on the forum.
I need to send to arduino a signal from a camera. I need this signal to be something like this.
The only way I can think about is using processing or OF and sending the equivalent signal to arduino.
I was wondering if there is a better way to keep everything on arduino, so that I don't have to use processing, OF or laptop.
So, in short, Ideally I would need an arduino connected camera to read a matrix of black and white pixels and send it back to Arduino.

Any hints anyone?

Cheers

That's not a "signal".

What kind of camera are you using? What format is the data in? How often do you need to update the data from the camera? For what purpose?

I am using a ov7670. I am not sure what you mean for the "data in" Camera update can be flexible. It doesn't need to be a continuous stream. The purpose is displaying the camera input on a sort of LED matrix.

Initially after seeing your sample images I though something like this would be ideal but no I read your using a OV7670 so it might be worth looking here instead. I remember someone on here doing quite a write-up on using a camera like this but since the forum upgrade I lost all my watched links so you will have to search for it.

Hi Riva,
I actually went through those links before. NIce and interesting but it wasn't working for me.
At the moment I decided to use OF. It will be probably more complex but I will have more control on the camera.

Thanks for your comment anyway:)
