Abstract

An IR camera includes a first optical subsystem for generating an IR image of an object and a second optical subsystem for generating a visual light image of the object. The IR camera further includes a focusing device for focusing the first optical subsystem. The IR camera also has a processor for determining a focus distance for focusing the first optical subsystem on the object. The processor determines the focus distance based on a displacement of a feature in the visual light image.
