Abstract

The invention discloses a driving device for a sight line zooming function of a mobile image sensor, and the device comprises a base, a mover module assembly movably connected to the base, a hook assembly fixed at a corner of the base, and a first group of coils and a second group of coils fixed on the base; hall chips are arranged in the first group of coils and the second group of coils, and the Hall chips are fixedly connected to the base. A mover module assembly is arranged in the base, the mover module assembly is located right above the first group of coils and the second group of coils and arranged at intervals, and the first group of coils, the second group of coils and the Hall chip form a closed-loop control module; the corner of the mover module assembly is elastically connected with the hook assembly, and the closed-loop control module controls the mover module assembly to drive and adjust the position in the X-Y axial direction. According to the invention, the image sensor is singly driven, and the OIS anti-shake effect is realized in a mode of not driving the lens.

Description

technical field [0001] The invention relates to the technical field of driving devices, in particular to a driving device for zooming function of the line of sight of a mobile image sensor. Background technique [0002] The photos taken by electronic devices such as mobile phones sometimes appear blurry during the shooting process, that is, the captured pictures are not clear enough, and ghosting or blurring occurs. These reasons, except for occasional out-of-focus (that is, the camera lens fails to focus normally), are largely caused by slight jitters when the scene is exposed. Generally speaking, this kind of extremely slight shaking phenomenon often occurs under handheld conditions, so the demand for the development of anti-shake technology functions is relatively large in recent years. In this context, proposals for OIS (Optical Image Stabilization System) optical image stabilization functions have also increased, and micro-optical image stabilization technology has gra...
