Abstract
An autofocus method of a camera, having an actuator controlling the position of a lens in an open-loop mode, includes receiving and analyzing an image captured using the lens and generating a face detection signal indicating whether a face is detected based on the analysis result. The size of the face is calculated when the face is detected, and a start position of the lens is determined based on the size of the face. A focus position of the lens is sought based on the start position of the lens.
