Abstract
Autofocusing is performed in response to a capturing object images upon which multiple depth estimation techniques are applied to yield a plurality of iterations. An iteration from one of these depth estimation techniques is selected based on results, such as based on largest absolute value, and checked. If the iteration fails the check, another of the iterations is selected and tested. Once a valid iteration is found, additional focus positions are executed in like manner from which an accurate focus position is determined.
