  • Patent number: 11125981
    Abstract: In a lens assembly structure comprising a plurality of lens assemblies, according to the present invention, at least one part of assemblies among the plurality of lens assemblies comprises: a first lens group having a positive refractive power or a negative refractive power; a second lens group having a positive refractive power; and a bending structure for bending an optical path of the first lens group such that the optical path corresponds to an optical axis direction of the second lens group, wherein the bending structure is disposed on the optical path of the first lens group and an optical path of the second lens group, optical axes of the first lens groups disposed in each of the at least one part of lens assemblies meet at one point, and optical axes of the second lens groups disposed in each of the at least one part of lens assemblies may form a triangle.

  • Patent number: 9857665
    Abstract: A photographing apparatus, a method of operating the photographing apparatus, and a wireless communication terminal including the photographing apparatus are provided. The photographing apparatus includes a first incident unit to which a first light is incident, a second incident unit to which a second light different from the first light is incident, an image sensor to which the first light and the second light are incident, a first light path changing unit configured to change a path of the first light from the first incident unit to the image sensor, and a second light path changing unit configured to change a path of the second light from the second incident unit to the image sensor.

  • Patent number: 9519139
    Abstract: A zoom lens barrel assembly includes a first barrel, a second barrel, a lens barrier, and a transparent member. The first barrel supports at least one lens. The second barrel surrounds at least a portion of an outer surface of the first barrel, and supports the first barrel to protrude along an optical axis direction. The lens barrier is disposed on a front side of the first barrel, and is moved in a direction that intersects an optical axis to expose the at least one lens when the first barrel is protruded. The transparent member is disposed on a front side of the lens barrier, and prevents impurities from entering the first barrel.

  • Patent number: 8325242
    Abstract: An image stabilizing apparatus may include a fixing member disposed to a lens assembly having a through hole of which a center coincides with an optical axis of the lens assembly, a moving member disposed to move perpendicular to the optical axis with respect to the fixing member having a lens holder projecting in a direction of the optical axis to hold a compensating lens, a driving portion causing the moving member to move in a first direction perpendicular to the optical axis and in a second direction perpendicular to the optical axis and the first direction, four position determining portions formed in the first direction and the second direction on an outer circumferential surface of the lens holder of the moving member, and four stoppers projecting from an outer circumferential surface of the through hole of the fixing member to the moving member.
