ABSTRACT:
An imaging apparatus is provided which performs optimum zooming and focusing even after long use. The imaging apparatus includes: a lens which is movable along the optical axis; a driving module to drive the lens; a driving amount calculation module to determine a drive count indicating the number of times the driving module has been operated or a drive time for which the driving module has been operated; a storage module to store compensation amounts which are used to compensate for the mechanical play of the driving module according to the drive count or the drive time; and a control module to control the driving module wherein a compensation amount appropriate for the drive count or time determined by the driving amount calculation module is selected from the compensation amounts stored in the storage module and the selected compensation amount is used to compensate for the mechanical play of the driving module.
