Title:
LONG-FOCUS MODULE, DOUBLE-CAMERA MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/016422
Kind Code:
A1
Abstract:
A long-focus module (100), a double-camera module (200), and an electronic device. The long-focus module (100) comprises a first prism (10), a first lens unit (20), a second prism (30), a second lens unit (40), and a sensing element (50); incident parts of the first prism (10), the first lens unit (20), and the second prism (30) form a first light incident path; an exit part of the second prism (30), the second lens unit (40), and the sensing element (50) form a second light incident path; and the second prism (30) inverts a light propagation path, so that the first light incident path and the second light incident path are located on the same side of the second prism (30). By means of the inversion design of the second prism (30), the light propagation path is divided into the first light incident path and the second light incident path, and the zoom lenses (20, 40) are respectively provided on the first light incident path and the second light incident path, so that the problem that the size of the long-focus module (100) is too large due to the zoom requirement is solved.
