Green Screen is a funny application for your Android mobile phone that allows you to create, in real-time, the "Chroma Key" or "Green Screen" effect when you are taking a photo. The Chroma Key is an effect often used in movies, interviews and weither forecast broadcasts, where someone (e.g. the meteorologist) stands in front of a green/blue screen, and then a picture (e.g. the weather map) is added on those parts in the image where the color is green/blue.

Instructions:
Press Menu Button, push on "set background" and select a background image from your device, select "Pick Key Color" and pick the color to replace (best with a bright uniform background), adjust the thresholds using the sliders in the left bottom corner of the screen. Take a photo touching the red button (it will be saved into your camera folder)!
