Embodiment Construction

[0085] An optical anti-shake device provided by an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0086] The optical anti-shake device in the embodiment of the present application can be applied to various types of lenses, including periscopes or various types of camera lenses, for example but not limited to, it can be applied to lens modules using mobile phones.

[0087] Some terms included in the embodiments of the present application are described below.

[0088] Focusing is also called light alignment and focusing. It refers to the process of changing the distance between the imaging surface and the lens according to the position of objects at different distances that are clearly imaged at the rear of the lens, so as to make the image of the object clear. Since all imaging systems have a depth of field, if the object to be photographed is outside the depth of field, the image of the object will be blur...

Abstract

The embodiment of the invention discloses an optical anti-shake device, which can maintain the stability of a camera and improve the photographing effect, can be applied to mobile phones, tablet personal computers and other terminal devices, and can also be applied to projection, 3D distance sensors and other devices. The optical anti-shake device comprises a first lens, a first reflecting mirror,a position sensor, a control part and a shell used for wrapping the first lens and the first reflecting mirror; the position sensor is connected with the control part; an optical signal is transmitted to the first reflecting mirror after passing through the first lens; the first reflecting mirror reflects the received optical signal, and the reflected optical signal is projected on the imaging surface; the position sensor is used for detecting jitter information of the first lens and sending the jitter information to the control part; the control part is used for controlling the first reflecting mirror to rotate with a first preset direction as the axis according to the jitter information, and the first preset direction is not parallel to the normal direction of the first reflector.

Description

technical field [0001] The present application relates to the field of optics, in particular to an optical anti-shake device and a control method. Background technique [0002] The digital camera function of the mobile phone refers to whether the mobile phone can take still pictures or short videos through the built-in or external digital camera. As a new additional function of the mobile phone, in recent years, the mobile phone camera capability has become the most concerned by consumers One of the indicator features. The realization of mobile phone photography benefits from the camera module to complete the image collection on the hardware, and relies on the operation of the algorithm on the software to finally obtain the photographing experience used by the user. In addition to the imaging function in the current mobile phone camera module, the most important technologies include zoom, anti-shake and focus technologies. [0003] As users become more and more dependent o...
