Problems solved by technology

However, the above-mentioned zoom device that realizes zooming by changing the actual distance between the lens groups is inconvenient to assemble because of its many components and complex structure.
In addition, because this kind of zoom is achieved by actually moving the front and rear lens frames, during the movement process, the phenomenon of relative eccentricity of the front and rear lens groups is prone to occur.

Abstract

A focusing device consists of the first lens set, the second lens set, the first refractive component and the second refractive component. Its focusing method includes reflecting light refracted by the first lens set to the second refractive component by the first refractive component and reflecting light emitted by the first refractive component to the second lens set by the second refractive component

Description

【Technical field】 [0001] The invention relates to a zooming device and method. 【Background technique】 [0002] With the continuous development of digital technology, digital cameras and portable electronic devices with digital cameras are becoming more and more popular in people's lives, and people have higher and higher requirements for image effects, appearance and volume of digital cameras. Because the zoom digital camera can change the focal length of object imaging, it can increase the shooting range and improve the image quality, so the application of the zoom device is more and more extensive. [0003] Please refer to image 3 , Chinese Patent No. 01122817.2 discloses a zoom device for a zoom camera, which includes a lens barrel 71, threaded rings 72, 74, guide rings 73, 75, inner rotating body 76, rear lens frame 77, front lens frame 70, mounted on The lens group (not shown in the figure) on the lens frame, front guide frame 78 and zoom ring 79 etc. Through the mut...
