Abstract
An auto focusing method for improving an auto focusing speed by implementing auto focusing by determining a motion direction of the focus lens at a current position of the focus lens, a recording medium for recording the auto focusing method, and an auto focusing apparatus. The auto focusing method is implemented by determining a current position of a focus lens; determining whether a first image input at the current position of the focus lens has image blurring; if the current position of the focus lens is a position for long range focusing and the first image has image blurring, determining that a motion direction of the focus lens is toward longer range focusing; and if the current position of the focus lens is a position for long range focusing and the first image has image blurring, determining that the motion direction of the focus lens is toward closer range focusing.
