Antishake focus lens module and control method thereof

Abstract

The invention relates to an antishake focus lens module and a control method thereof. The antishake focus lens module includes an antishake module and a lens module, wherein the antishake module is provided with an antishake frame, a barycenter adjusting device, a plurality of coils, a plurality of magnet groups, a gyroscope and three Hall sensors, the antishake frame is movably installed on a shell, and the lens module is fixed to the antishake frame; the gyroscope is arranged on the rear part of a lens module (changing to a whole module), the multiple magnet groups are arranged on the innerside of the shell in the circumferential direction of the lens module, the three Hall sensors are installed on the three positions of the antishake frame, the multiple coils are distributed on the antishake frame in the circumferential direction of the lens module, each coil is arranged in conjunction with the corresponding magnet group, and a receiving current in each coil is matched with the corresponding magnet group to drive the antishake frame to move; and the current is determined through output of the gyroscope and/or Hall sensors, and the barycenter makes the barycenter of the whole antishake focus lens module such as the antishake frame coincide with the rotating center of the antishake frame. Imaging remains stable, and the problem of image blurring caused by camera vibration orshake can be effectively solved.

Description

technical field [0001] The invention relates to the field of fixed-focus lens driving devices, in particular to an anti-shake fixed-focus lens module and a control method thereof. Background technique [0002] With the continuous development and progress of technology, consumers have higher and higher requirements for the imaging quality of portable digital cameras, and the application of anti-shake technology on digital cameras has become an inevitable trend. At present, most cameras on the market basically use CCD Anti-shake technology, however, CCD anti-shake technology imaging cannot maintain enough stability, and there is a phenomenon that the image blur caused by camera vibration or shaking cannot be overcome. Contents of the invention [0003] The present invention aims to overcome at least one defect of the existing anti-shake lens, and provides an anti-shake fixed-focus lens module and a control method thereof, which maintain stable imaging and can effectively ove...
