ABSTRACT:
An auto-focus (AF) camera enables AF operation with high speed and enhanced accuracy. The AF operation encompasses step-scanning the focus lens of the camera from the closest focal position to infinity, or vice versa. In one embodiment, the steps in the step-scanning are made smaller around a position judged to be close to the focus position, and the steps are made larger at other positions.
