Optical zooming camera module and mobile terminal provided with optical zooming camera module

Abstract

The invention provides an optical zooming camera module. The optical zooming camera module comprises an optical zooming lens group and an image sensor, and is characterized in that the optical zooming lens group comprises a light incidence lens, a light converting lens and a reflective mirror, wherein the reflective mirror is provided with a reflective slope; the light converting lens and the reflective mirror are positioned at the two ends of the optical zooming lens group; the center line of the light incidence lens is vertical to a center connecting line between the light-converting lens and the reflective mirror; the image sensor and the light incidence lens are positioned on both sides of the center connection line between the light converting lens and the reflective mirror, and are arranged oppositely; the reflective slope faces the image sensor, and is used for receiving light rays entering through the light incidence lens and reflecting the light rays to the image sensor. The invention further provides a mobile terminal.

Description

technical field [0001] The invention relates to the field of camera modules, in particular to an optical zoom camera module and a mobile terminal with the optical zoom camera module. Background technique [0002] The optical zoom device zooms in and out of the scene to be photographed by moving the lens of the camera. A common optical zoom device in the prior art mainly includes a zoom lens group and an image sensor; the outer lens of the zoom lens group is located on the same side as the image sensor. However, in current thin and light electronic equipment such as mobile phones or tablet computers, when the camera uses the above-mentioned optical zoom device, the arrangement of the zoom lens group and the image sensor are all arranged along the length direction of the mobile phone, and the external lenses of the zoom lens group should be located at In the middle and upper part of the back of the mobile phone, the optical zoom camera module is relatively square, occupying s...
