Abstract
Disclosed is an apparatus and method for auto-focusing a camera, which includes the steps of detecting an initial value of an encoder by measuring an initial position of a lens system, matching the measured initial value of the encoder with the initial position value of the lens system to be moved, measuring a distance value of a subject through a distance measuring sensor, determining a displacement that a focus lens has to be moved with respect to the measured distance value, and adjusting a position of the focus lens such that a position value of the focus lens actually moved is the same as the displacement value.
