  • Publication number: 20180367784
    Abstract: A camera module is provided. The camera module includes a number of camera assembles. Each of the camera assembles includes a lens unit and an electromagnetic driving unit. The electromagnetic driving unit includes at least one magnetic element for controlling the movement of the corresponding lens unit. The distance between two of the magnetic elements, which are closest to each other and respectively positioned in two of the camera assemblies, is greater than the distance between two of the light through holes, to which the two of the camera assemblies are arranged to correspond.

  • Publication number: 20180164539
    Abstract: A camera module is provided, including a lens holder, a driving mechanism, a frame, a base, a sensing element, and a plurality of three-dimensional circuits. The lens holder carries a lens with an optical axis. The driving mechanism is configured to drive the lens holder along the optical axis. The frame receives the driving mechanism and the lens holder therein. The base supports the frame, and a recess is formed on the bottom of the base. Specifically, the recess is formed by the outer periphery of the bottom of the base extending toward the light-exit direction of the optical axis. The sensing element is disposed in the recess. The three-dimensional circuits are formed in the recess and electrically connected to the sensing element and the driving mechanism.

  • Patent number: 8213099
    Abstract: A miniature auto-focusing lens device includes a first casing, a second casing coupled to the first casing, a movable lens set disposed in the first casing, an electromagnetic driving module provided in the first casing and configured to drive the movable lens set to perform focusing and displacement, and a fixed lens set coupled to the second casing and corresponding in position to the movable lens set. The movable lens set and the fixed lens set together form an optical system of the miniature auto-focusing lens device to perform optical focusing and imaging. The fixed lens set includes a lens that outstrips any one of the lenses of the movable lens set in size.

  • Patent number: 8098443
    Abstract: A miniature zoom lens system comprises three lens groups having four lenses in total. The first lens group has negative power and is fixed. The second lens group has positive power and includes two lenses. An aperture is furnished in front of and movable with the second lens group. The third lens group has positive power. The second and third lens groups are movable along an optical axis between a wide-angle position and a telephoto position. The system fulfills the following conditions: 11.5<Dw1-2/Dw2-3<18.5; and Dt1-2/Dt2-3<0.2. Wherein, Dw1-2 and Dt1-2 respectively are the air spacing between the first and second lens groups at the wide-angle position and the telephoto position; Dw2-3 and Dt2-3 respectively are the air spacing between the second and third lens groups at the wide-angle position and the telephoto position.
