Abstract:
A camera module includes a lens module including at least one lens; a housing in which the lens module is disposed; a magnet disposed on the lens module; a coil facing the magnet; a first yoke member fixed to the housing; and first and second ball units disposed between the lens module and the housing, spaced apart from each other in a first direction perpendicular to an optical axis, and each including a plurality of balls disposed in a direction parallel to the optical axis, wherein the lens module includes a first extension protruding in the direction parallel to the optical axis, the housing includes a second extension protruding in the direction parallel to the optical axis and accommodating at least a portion of the first extension, and at least one ball among the balls included in the first and second ball units is disposed between the first and second extensions.
Abstract:
A folded module includes a housing, a carrier provided in the housing, and a rotation holder provided on the carrier and including a reflective member. The carrier is rotatable, with respect to the housing, around a first axis formed by one rotating shaft ball, the rotation holder is rotatable with respect to the carrier around a second axis formed by two ball members, and the first axis and the second axis intersect each other, and the one rotating shaft ball and the two ball members are provided together on a plane on which both the first axis and the second axis are provided.
Abstract:
A camera module includes: an optical path folding member configured to refract or reflect light incident along a first optical axis in a direction of a second optical axis intersecting the first optical axis; a driving assembly configured to provide driving force to rotate the optical path folding member on a plane intersecting the first optical axis; and a first ball bearing and a second ball bearing supporting the optical path folding member such that the optical path folding member is enabled to rotate on the plane. A distance from the first ball bearing to the first optical axis is less than a distance from the second ball bearing to the first optical axis.
Abstract:
A camera module includes: a housing having a connection electrode; a fixed lens disposed in the housing and arranged on an optical axis; an actuator mounted in the housing and connected to the connection electrode; and a movable lens coupled to the actuator and configured to be moved by the actuator, the movable lens being disposed on the optical axis.
Abstract:
A system and a method of measuring and correcting an angle of tilt of a lens are provided. A resolution of the lens is measured using a test chart, and it is selected whether or not a tilt of the lens is corrected depending on whether or not the measured resolution of the lens is equal to or greater than a preset value. Whereby, productivity of a camera module may be improved.
