Google has filed for a patent that would adjust camera settings for optimal performance based on GPS coordinates and the current weather conditions. Depending on where you are, and what the weather might be like if it's determined that you're outdoors, settings like white balance, ISO, exposure value and all those other camera settings most people never touch can be tweaked using the data collected. This means that the settings of the camera can be adjusted on-the-fly for the perfect shot.
We have no idea if Google will ever use this one, or if it's even a worthwhile feature, but Senior VP of engineering Vic Gundotra did promise making Nexus phones with "insanely great cameras". And while we're over patents and the never-ending war that seems to go along with them, this one was too cool to not talk about.
