Telescopic continuous zoom optical lens, imaging assembly and mobile phone

Abstract

The invention discloses a telescopic continuous zoom optical lens, an imaging assembly and a mobile phone. The telescopic continuous zoom optical lens comprises a lens main body, and the lens main body comprises a lens cone, a zoom lens group and a compensation lens group; the zoom lens group comprises a first lens group with negative focal power and a second lens group with positive focal power, the compensation lens group comprises a third lens group with positive focal power and a fourth lens group with negative focal power, and the first lens group, the second lens group, the third lens group and the fourth lens group can move forwards and backwards; and the focal lengths of the first lens group, the second lens group, the third lens group and the fourth lens group are f1, f2, f3 and f4 respectively, the distances between the first lens group and the second lens group at the wide-angle end and the telephoto end are dw12 and dt12 respectively, and the distances between the third lens group and the fourth lens group at the wide-angle end and the telephoto end are dw34 and dt34 respectively. The application of the lens main body to electronic equipment such as a mobile phone and the like is facilitated.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a retractable continuous zoom optical lens, an imaging component and a mobile phone. Background technique [0002] Taking mobile phone lenses as an example, mobile phone camera lenses, as the standard configuration of smart phones, have shown a rapid growth trend in recent years. With the increasing development of mobile phone camera lenses, people have put forward higher requirements for the performance and quality of mobile phone lenses. Especially in the zoom mobile phone lens, the traditional digital zoom can no longer meet the growing consumer demand. [0003] At present, the zoom scheme adopted in smart phones is mainly digital zoom. Digital zoom is to increase the area of ​​each pixel in the picture through the processor in the digital camera, so as to achieve the zoom effect of zooming in on the picture. If the digital zoom is increased, the picture quality will c...

[0003] At present, the zoom scheme adopted in smart phones is mainly digital zoom. Digital zoom is to increase the area of ​​each pixel in the picture through the processor in the digital camera, so as to achieve the zoom effect of zooming in on the picture. Increase, digital zoom will lead to continuous decline in image quality

Traditional optical zoom lenses cannot be applied to smartphones due to problems such as large size
