Abstract

The invention provides a zooming shooting module which at least comprises a focusing lens set, a zooming lens set, a focusing driving element, a zooming driving element, an optical sensing element and a vibration sensing element, wherein the focusing driving element at least comprises a first moveable component, a first fixed component and a first electric unit; the first electric unit can supply an axial displacement and at least one axial inclined angle compensation; the zooming driving element at least comprises a second moveable component, a second fixed component and a second electric unit; the second electric unit can supply an axial displacement; and the axial inclined angle compensation which is supplied by the first electric unit of the focusing driving element can also be supplied by the second electric unit of the zooming driving element.

Description

technical field [0001] The present invention relates to a camera module, in particular to a zoom camera module used in a digital camera or a mobile phone camera. Background technique [0002] In recent years, with the rapid development of various electronic products, people's demand for digital products is increasing, especially the quality of camera shooting is more stringent, hoping to record the details of life with high-quality images. [0003] However, the vast majority of known zoom photography lenses used in digital cameras or mobile phone cameras are digital zoom, or even only support part of the optical zoom function. In operation, the image is only enlarged and displayed, or the maximum pixel is first shot and then , and then capture the picture with the same pixels as the original pixels, so the photographic lens will not move in the direction of the optical axis. Compared with the picture pixels of the unenlarged picture, the pixels of the picture taken after the...
