Title:
ZOOM LENS, ZOOM METHOD, TERMINAL, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/259386
Kind Code:
A1
Abstract:
A zoom lens (1), a zoom method, a terminal, and a computer-readable storage medium. The zoom lens (1) comprises: n lenses (10), the n lenses (10) being sequentially arranged in an optical axis direction, and n being a positive integer greater than or equal to 2; a diaphragm (11) arranged parallel to the n lenses (10) in the optical axis direction; and an imaging surface (12) provided at an end of the optical axis and parallel to the n lenses (10). The n lenses (10) comprise m variable curvature lenses and n-m aspheric lenses (101). Driving devices are provided at a top end and a bottom end of each of the m variable curvature lenses, where m is a positive integer greater than 1 and less than n. When power of the driving devices corresponding to the m variable curvature lenses is changed, the radii of curvature of the m variable curvature lenses are changed, and an incident angle is acquired. After incident light corresponding to an object space is received, the incident light is reflected to the imaging surface (12) at the incident angle under a light convergence effect of the diaphragm (11) and by means of the n lenses (10), so as to perform imaging.
