Abstract
A driving apparatus, a lens unit, a device, a correction method, and a computer readable recording medium are provided, the driving apparatus including an actuator that changes a relative position between a lens section and an imaging device; a magnetic field detection section that detects magnetic field information corresponding to the relative position between the lens section and the imaging device; a storage section that stores reference information that is based on an output of the magnetic field detection section when the lens section or the imaging device is positioned at the reference position; and a control section that controls a driving amount of the actuator based on the magnetic field information and the reference information.
