Abstract
A system and method of determining a tilt angle of a portable computing device using a sensor indicating gravitational pull on the device; determining the tilt angle of a camera of the device; identifying a tilt angle range from a plurality of predetermined tilt angle ranges; determining a first focal length setting using a first array that associates the tilt angle range with the first focal length setting; determining an adjustment increment using a second array that associates the adjustment increment with the tilt angle range; and determining a second focal length setting of the camera using the adjustment increment according to an autofocus scan range algorithm. A portable computing device including a processor; a camera; and a memory device including instructions operable to be executed by the processor to perform a set of actions, enabling the portable computing device to perform the method.
