Lens of cell phone panoramic camera, panoramic camera, and imaging method

Abstract

The invention discloses a lens of a cell phone panoramic camera, a panoramic camera, and an imaging method. The lens is a wide-angle lens used for condensation, and is a negative lens comprising a concave surface and a convex surface, and an ion film plating layer is coated on the convex surface. The film plating material of the ion film plating layer adopts SiO2, TiO2, and fluorocarbon alkyl compound. The SiO2 and the TiO2 are used for alternate sputtering for film plating, and the fluorocarbon alkyl compound disposed on the outmost layer. The thickness of the ion film plating layer is in a range from 360nm to 600nm, and the reflectivity of the ion film plating layer in a visible light range is smaller than 7%. The lens adopts the negative lens capable of realizing field angle exceeding 200degrees, and the panoramic camera constituted by two lenses is capable of satisfying imaged panoramic stitching effect. The ion film plating layer is coated on the convex surface of the lens, and then loss of incident light is reduced, and anti-friction performance is provided. The thickness of the cell phone panoramic camera is reduced to be within 12mm, and therefore a size of a panoramic shooting device is small, and the panoramic shooting device can be used for cell phone panoramic shooting.

Description

technical field [0001] The invention relates to a panoramic lens, in particular to a lens of a mobile phone panoramic lens, a panoramic lens and an imaging method. Background technique [0002] Existing mobile phone lenses are divided into front and rear lenses through software switching and are imaged and displayed separately. There is no way to synthesize the same panoramic image, and the only lens on the market that realizes panoramic shooting at the same time and space Because its lens module is too thick, it cannot be integrated into a mobile phone and used at will. It is only a dedicated panoramic shooting tool. [0003] Because the lens combination used by the existing panoramic lens module in the exposed first incident part adopts two or more lenses to increase its field of view, and it is popular to complete the imaging in the form of double lenses back-to-back As a result, this will inevitably increase the thickness of the entire module of the lens, which is unacc...

AI Technical Summary

Problems solved by technology

[0006] 1. The VR lens set is too thick to be applied to portable terminals;

[0007] 2. The panoramic lens has a curved surface, which is not resistant to scratches, and the reflectivity is relatively high after conventional hardening coating treatment
