Abstract
An electronic system for enhancing camera focusing on a portable electronic device is disclosed. The system comprises a body, a bus, and a camera module coupled to the bus and comprising a photosensitive substrate and a lens assembly wherein the lens assembly comprises a lens capable of being selectively moved to a distance from the photosensitive substrate for light focus thereon. Further, it comprises an accelerometer coupled to the bus and configured to generate orientation information, said orientation information indicating contemporaneous orientation of the body with respect to a predetermined reference. It also comprises a memory and a processor coupled to the bus. The memory comprises instructions that when executed implement an autofocus program configured to automatically determine the distance based on: 1) image data captured by said camera module; and 2) the orientation information generated by the accelerometer.
