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 actuator current or voltage information or focusing lens position 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. The use of such focusing information can also mitigate the undesirable effects of production variations and/or component wear.

The invention claimed is: 1. A method for focusing, the method comprising:storing image sharpness scores and corresponding focus actuator drive signals for a plurality of previous photographs to form stored data;for a current photograph, determining a current image sharpness score and a corresponding current image focus actuator drive signal;comparing the current image sharpness score and the current image focus actuator drive signal to the stored data to determine an initial focus actuator drive signal; anddriving a focus actuator according to the initial focus actuator drive signal to achieve an initial focus lens position for a focus lens.
