Problems solved by technology

The existing optical anti-shake structure is relatively complicated. For example, the focus component is moved by the moving platform, so that the focus component drives the lens to move along the direction perpendicular to the optical axis of the lens to compensate for the shake displacement.
However, these structures cause an increase in the overall size, which is not conducive to the thinning of the imaging device

Embodiment Construction

[0045] see figure 1 , figure 1 It is a structural block diagram of an imaging device provided by an embodiment of the present application. An imaging device 200 includes an anti-shake autofocus device 100 , an image sensor 201 , a position sensor 203 and a processor 205 . The imaging device 200 may be a smart phone, a smart watch, a tablet computer, a personal digital assistant (personal digital assistant, PDA), a sales terminal (point of sales, POS), a vehicle computer, a desktop computer, a notebook computer, a smart TV, a game machine, etc. kind of. The image sensor 201 is used to generate image information from the light captured by the anti-shake autofocus device 100 . The position sensor 205 is used to acquire shake information of the imaging device 200 . The processor 205 is configured to control the anti-shake auto-focus device 100 to perform automatic optical anti-shake focusing according to the shake information.

[0046] The imaging device 200 also includes a c...

Abstract

The embodiment of the application provides an anti-shake automatic focusing device and camera equipment. The anti-shake automatic focusing device comprises a lens, an automatic focusing part, a supporting elastic body, a pressing piece part and an anti-shake actuator, the lens is arranged on the automatic focusing part, the pressing piece part comprises a pressing piece and a bottom plate which are fixedly connected, and the first end of the supporting elastic body is fixed to the automatic focusing part. The second end of the supporting elastic body is fixed on the bottom plate, so that the automatic focusing part is supported by the supporting elastic body and is positioned on one side, deviating from the bottom plate, of the pressing sheet; the anti-shake actuator is fixed between the end, facing the pressing piece part, of the automatic focusing part and the pressing piece and used for driving the automatic focusing part and the lens to swing with the joint of the second end of the supporting elastic body and the bottom plate as the base point when power-on deformation is conducted. Therefore, the structure of the anti-shake automatic focusing device is simplified, the thickness of the anti-shake automatic focusing device in the extending direction of the optical axis of the lens is reduced, and lightening and thinning of the camera equipment are facilitated.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to an anti-shake autofocus device and camera equipment. Background technique [0002] When a camera device with a camera function, such as a mobile phone, a tablet computer, etc. takes a camera, the photos taken by it will often appear blurred, ghosted or blurred due to slight shaking. With the continuous maturity and expansion of the camera equipment market, the demand for high performance of camera equipment continues to increase, which also puts forward the automatic focus (Automatic Focus, referred to as AF) function and optical image stabilization (Optical image stabilization, referred to as OIS) function of the camera equipment. higher requirements. The existing optical anti-shake structure is relatively complicated. For example, the focus component is moved by a moving platform, so that the focus component drives the lens to move in a direction perpendicular to the optical a...
