A camera module includes a movable portion including a lens barrel, an accommodating portion configured to receive the movable portion, and a driving unit configured to drive the movable portion, comprising a driving magnet integrated with the movable portion. A cross-sectional area of the driving magnet decreases as a distance thereof from an optical axis increases.

An actuator for a camera according to an embodiment includes a base having an inner space formed therein, a carrier provided inside the base and configured to move in at least one direction among an optical axis direction, a first direction perpendicular to the optical axis and a second direction perpendicular to the optical axis and the first direction; and a damper provided to the carrier or the base and configured to have a shape extending in two or more directions among the optical axis direction, the first direction and the second direction.

An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, and a stopping assembly. The movable portion is used for connecting to an optical element having a main axis. The movable portion is movable relative to the fixed portion. The driving assembly is disposed on the fixed portion or the movable portion to move the movable portion relative to the fixed portion. The stopping assembly connects to the movable portion and the fixed portion to limit the range of motion of the movable portion relative to the fixed portion.

An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion, a fixed portion, a first driving assembly, and a plurality of second guiding members. The first movable portion is configured to connect an optical member. The optical member is used for adjusting a direction of a light from an incident direction to an outgoing direction. The first movable portion can move relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion. The second guiding members include a first ball, a second ball, and a third ball. The first ball, the second ball, and the third ball are disposed in a plane that is perpendicular to the incident direction.

A camera actuator according to an embodiment includes a housing; a prism unit disposed in the housing; and a first driving unit for tilting the prism unit; wherein the prism unit includes: the prism; and a prism mover disposed to surround the prism, and a second driving unit disposed between the prism and the prism mover and tilting the prism, and wherein a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit.

A vibratory actuator control apparatus includes a vibrating member, having an electro-mechanical energy conversion element, and a contact member that contacts the vibrating member. In a second case where the vibrating member and the contact member are brought from a stationary state to a stopped state, an operation sequentially passes through a third stage and a fourth stage. The third stage is for decelerating a relative movement driving speed by applying a driving voltage to the electro-mechanical energy conversion element while maintaining a control parameter of the driving voltage constant and increasing a driving frequency. The fourth stage is for decelerating the driving speed by applying the driving voltage to the electro-mechanical energy conversion element while maintaining the driving frequency constant and decreasing the control parameter of the driving voltage. A start frequency is set based on the driving frequency corresponding to a predetermined driving speed in the third stage.
