ABSTRACT:
A method and system for effecting adaptive autofocusing, such as for a camera, are disclosed. The method can comprise obtaining focusing information, such as historic focusing information, storing the focusing information, and subsequently using the focusing information to facilitate a determination of a best position of a focusing lens during a focusing process. The use of such focusing information can result in a better choice for the next focusing lens position to be tested, such that the focusing process can be performed more rapidly.
