Several iPad 2's have been reported to have a color glitch problem (similar to what is shown above) with their cameras (both front and rear camera). According to the report, this doesn't happen all the time, and if it does, it usually takes a split second or two. It shouldn't be a problem for most people and hopefully its just a software issue , to be easier to fix on the next software update.
