  • Patent number: 9491363
    Abstract: An automatic tuning method for an OIS camera module, comprising the steps of: S0, providing an automatic tuning platform (1), and enabling an OIS camera module (2) to directly face an objective plane (103); S1, a control module (101) indicating to an OIS motor controller (201) to control an OIS motor (203), thereby changing the stroke of a lens; S2, changing control parameters of each driver or each pair of drivers in sequence, and recording the control parameters, compensation angles and a relative angle each time the control parameters of one or one pair of drivers are changed; S3, according to the control parameters, the compensation angles and the relative angle, the control module (101) calculating an OIS gain in each stroke; and S4, transmitting the OIS gain in each stroke to the OIS motor controller (201).

  • Publication number: 20150187066
    Abstract: Disclosed is a device for rapidly and comprehensively inspecting a lens actuator, the device comprising a bracket (4) for fixing the lens actuator, a cone-shaped body (2) and a camera (1), wherein the outer surface of the cone-shaped body (2) is a mirror surface, the cone-shaped body (2) is mounted on the top of the bracket (4), and the camera (1) is hung above the cone-shaped body (2). Further disclosed is a system employing the above-mentioned device for rapidly and comprehensively inspecting a lens actuator, and a method for inspecting a lens actuator by using the above-mentioned device. A rapid inspection can be realized so as to facilitate quality inspection and control in mass production, and a comprehensive inspection also can be realized, the inspection items including lens stroke, magnitude of inclination and the similar items under different control conditions.
