I'd like to build from scratch a color meter for iphone: an app where you point the camera at something and you get the rgb values back. easy. the app store is plenty of apps like that but i'd like to use it as case study for future explorations.

does anyone know where i can start with? any framework already available or even better an app already built an available as opensource?

thanks!
