发明名称 Imaging apparatus and portable apparatus
摘要 An imaging apparatus comprises: an imaging lens; an image pickup device that is placed behind the imaging lens; a lens drive portion that includes a magnet that forms a magnetic field and a coil, placed in the magnetic field, that, upon an input of a current signal, receives a force in an optical axis direction to move the imaging lens to a position corresponding to the current signal, the lens drive portion holding the imaging lens, and moving the imaging lens to the position corresponding to the current signal in the optical axis direction; and a movement control portion that, when the imaging lens is to be moved, gives to the lens drive portion, a current signal that is gradually changed from a first current signal corresponding to a first position before movement of the imaging lens, to a second current signal corresponding to a second position after movement.
