Abstract

The embodiments of the invention provide a zoom lens, a zoom method, a terminal and a computer readable storage medium. The zoom lens includes n lenses; the n lenses are successively arranged in an optical axis direction; n is a positive integer greater than or equal to 2; an aperture is arranged parallel to the n lenses in an optical axis direction; the aperture is arranged at the tail end of theoptical axis and parallel to the n lenses to form an image plane; the n lenses include m variable curvature lenses and n-m aspherical lenses; the top end and bottom end of each variable curvature lens of the m variable curvature lenses are provided with driving parts; m is a positive integer greater than 1 and less than n; by changing the power of the driving parts corresponding to the m variablecurvature lenses, the radiuses of curvature of the m variable curvature lenses are changed, and an incident angle is obtained; and after receiving incident light corresponding to an object space, under the action of a beam of light of the aperture, and through the n lenses, the incident light is reflected to the image plane to be an image at an incident angle.

Description

technical field [0001] The embodiments of the present application relate to an optical zoom technology in the electronic application field, and in particular to a zoom lens, a zoom method, a terminal, and a computer-readable storage medium. Background technique [0002] A zoom lens refers to a lens that can change the focal length within a certain range, so as to obtain different wide and narrow field of view angles, different size images, and different scene ranges. That is to say, the zoom lens can change the shooting range by changing the focal length without changing the shooting distance. Therefore, one zoom lens can realize the functions of several fixed-focus lenses, which is very conducive to picture composition. The zoom lens is applied to the terminal to realize the shooting function. [0003] At present, when the zoom lens on the terminal is used to realize zooming, the motor control is used to change the arrangement distance of the lenses in the zoom lens to cha...
