Abstract
An image-based motion sensor has a camera system and a processing system. The camera system generates an image output including a plurality of captured images. The processing system obtains a motion sensor output by processing the image output, and identifies a user input as one of a plurality of pre-defined user actions according to the motion sensor output. Different functions of at least one application performed by one electronic device are controlled by the pre-defined user actions. The motion sensor output includes information indicative of at least one of a motion status and an orientation status of the image-based motion sensor. Each of the captured images has more than one color component, and only values of one single color component are involved in obtaining the motion sensor output.
