Classification: CPC H | IPC H

Claim 0:
1. A computer-implemented method, comprising:
performing, by one or more processors of a camera device:
prior to a camera session, determining a position offset based at least in part on a difference between a known current position of a camera lens relative to a photosensor and a sensed current position of the camera lens relative to the photosensor determined from position sensor data; and
responsive to determining the position offset is valid, using the determined position offset during a camera session, comprising:
controlling the position of the camera lens relative to the photosensor in a first control mode that calculates the position using a lens position sensor, the controlling comprising repeatedly adjusting the position in a control loop based at least in part on the position sensor data and the determined position offset.
