I am currently working on a project where I am using Jitter for colour-tracking. I have 4 different colour balls which are being tracked with jit.findbounds. Whenever I set up the system, I have to spend a while configuring the different colours (depending on the light of the room) so that Jitter knows which colours to track. Does anyone know a way to create a white balance, so that I simply have to show the camera a white object, and it’ll work out what colours is should be looking for?

Thanks ever so much for the patch Nesa! (sorry about the delay in replying, I’ve had problems with my internet). I have to confess that I don’t understand what this patch is doing at all!! I’ve been doing quite a lot of head-scratching trying to work it out. If you don’t mind, could you give me an idea of what is happening conceptually in the patch? I’m sorry for my ignorance, I’m very new to Jitter to be honest.
Thanks again for your help,
