Method for controlling auto focusing of a camera

Abstract

A method for controlling auto focusing of a camera, which heretofore involved severe hunting phenomena in the case of a low depth of focus due to arbitrarily determining a wobbling width of a focus lens free from the depth of focus (iris opening), utilizes an opening of an iris and position of a zoom lens. The iris opening and zoom position are detected to variably control the wobbling width of the auto focusing, thereby improving the auto focusing speed. This minimizes wobbling and prevents hunting in the case of a low depth of focus.
