Embodiment Construction

[0044] Embodiments of the present application provide an optical image stabilizer, an optical image stabilizer system and a control method thereof. The stabilizer and the stabilizer system can be applied to electronic devices with a camera function, such as mobile phones, tablet computers, Electronic devices such as digital cameras. The optical image stabilizer of the embodiment of the present invention includes a first electrode and a second electrode. When an impact is about to occur, the first and second electrodes of the optical image stabilizer are in the energized state to set the bearing capacity of the first electrode. The platform and the base on which the second electrode is installed are attracted by electrostatic force, so the floating state of the image sensor carried by the platform disappears, and the stabilizer as a whole becomes a fixed structure, which is not easy to be damaged during the impact process. And because the magnitude of the electrostatic force is...

Abstract

The embodiment of the invention provides an optical image stabilizer, an optical image stabilizer system and a control method thereof. The optical image stabilizer and system may be used in a camera module of an electronic device, where the optical image stabilizer includes an actuation member and an image sensor, and the actuation member includes a bearing table, a substrate, a first electrode, and a second electrode. The bearing table bears the image sensor, the first electrode is arranged on the surface, facing the substrate, of the bearing table, and the second electrode is arranged on thesurface, facing the bearing table, of the substrate. When impact is about to happen, the bearing table provided with the first electrode and the substrate provided with the second electrode are attracted through the electrostatic attraction effect of the first electrode and the second electrode, and therefore the optical image stabilizer is free of a suspension structure. When an impact occurs, the optical image stabilizer can be prevented from being damaged.

Description

technical field [0001] The present application relates to the technical field of electronics and communication, and in particular to an optical image stabilizer, an optical image stabilizer system and a control method thereof. Background technique [0002] People often use electronic devices (such as smart phones, tablet computers, etc.) to take pictures in daily life, so the photo quality of electronic devices has become one of the important criteria for measuring electronic devices. [0003] The shaking of the electronic device during the process of taking pictures and taking pictures will cause the image presented by the object to be photographed on the image sensor, such as a CMOS image sensor (CMOS image sensor, CIS), to shift. The optical image stabilizer (Optical image stabilizer, OIS) is used to reversely move the mirror group or move the CIS to compensate for the displacement of the mirror group and CIS due to the shaking of the electronic device during the exposure...
