摘要： 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.

摘要： An aperture module includes a rotation plate disposed on a base, a moving portion that moves linearly to rotate the rotation plate, and blades linked to the rotation plate to form an aperture having a variable size. The blades include at least two small-aperture blades that are contracted inwardly toward an optical axis to form the aperture having a first size and at least two medium-aperture blades that are contracted inwardly toward the optical axis to form the aperture having a second size larger than the first size. The at least two small-aperture blades and the at least two medium-aperture blades are extended outwardly away from the optical axis to form the aperture having a third size larger than the second size.
