Abstract
An autofocus method determines that a ranging device of a digital camera has failed in an attempt to provide a distance estimation. The ranging device provides one or more parameters indicating conditions related to the failure of the ranging device to provide the distance estimation. An autofocus sequence based on the one or more parameters is then performed.
