Functional testing

The proper functionality of autofocus can mean the difference between a sharp photo and a missed opportunity.


The autofocus system intelligently adjusts the camera lens to obtain focus on the subject. Autofocus testing verifies that camera optics are working, and the camera is able to focus as specified.


An artificial focal length is created using a lens. The device camera takes a picture of a reference image. A machine-vision algorithm processes the picture for accurate focus.
