Abstract
An automatic focal adjustment apparatus capable of focusing at a distance appropriate for an object at infinity, and a method of controlling the automatic focal adjustment apparatus, are disclosed. The automatic focal adjustment apparatus detects an in-focus position of a focus lens based on an AF evaluation value generated from an image signal. Also, the automatic focal adjustment apparatus moves the focus lens to the detected in-focus position when the detected in-focus position is within a predetermined range from a reference position determined in advance corresponding to an object at a infinity distance.
