In digital camera terminology face detection, also called face-priority AF (auto focus), is a function of the camera that detects human faces so that the camera can set the focus and appropriate exposure for the shot automatically. When using a flash, face detection will also usually and automatically correct or remove the unwanted red-eye effect that can often occur when photographing people using a flash.
