Imaging device and method of driving imaging device

摘要

An imaging device includes an acquisition unit acquiring a defocus amount for an optical image which is obtained by an imaging element, a recording unit recording a driving speed of lens with the defocus amount in response to an instruction from a user, wherein the lens is controlled, for adjusting a position at which the optical image is focused, by a lens driving unit, an information generating unit generating lens driving information specifying a relation between the defocus amount and the lens driving speed, and a control unit controlling the lens driving unit so as to move the lens to a position at which the optical image is in-focused to the object at a predetermined speed specified in the lens driving information as a driving speed corresponding to the defocus amount acquired by the acquisition unit.

1. An imaging device comprising:
an acquisition unit configured to acquire a defocus amount for an optical image which is obtained by an imaging element; a recording unit configured to record a driving speed of a lens in association with the defocus amount in response to an instruction from a user, wherein the lens is controlled, for adjusting a position at which the optical image is focused, by a lens driving unit; an information generating unit configured to generate lens driving information specifying a relation between the defocus amount and the driving speed of the lens based on information of the driving speed recorded by the recording unit; and a control unit configured to control the lens driving unit so that the lens is moved to a position at which the optical image is in-focused to the object at a predetermined speed specified in the lens driving information as a driving speed corresponding to the defocus amount acquired by the acquisition unit.
