Abstract

A lens assembly, an image capture device and a zoom control method thereof. The lens assembly includes a first lens group, a second lens group, a third lens group, a fourth lens group, and a fifth lens group, all of which are arranged in order from a first side to a second side along an axis. The first lens group is with negative refractive power. The second lens group is with positive refractive power. The third lens group is with refractive power. The fourth lens group is with refractive power. The fifth lens group is with refractive power. The lens assembly further includes a first reflective element disposed between the first lens group and the fifth lens group, wherein the first reflective element includes a first reflective surface.

Description

Technical field [0001] The present invention relates to an imaging lens, an image capture device, and a zoom control method thereof. Background technique [0002] The development of optical zoom technology has been quite mature, and a large number of optical zoom lenses are used in digital interchangeable lens single-eye cameras or general numbers that cannot be exchanged camera. Since the total length of optical zoom lens is longer, and the length of the lens with the zoom ratio Human, today, a lightweight smart phone is now unable to assemble the optical zoom lens of the traditional architecture. So there is a need for another new architecture to meet miniaturization, high resolution and optical zoom function, in order to meet the needs of intelligent phones on optical zoom functionality. Inventive content [0003] The technical problem to be solved by the present invention is that the imaging lens in the prior art cannot simultaneously satisfy the miniaturization, high resolu...
