Abstract

The invention discloses a method for compensating imaging quality of an optical system through adjustment of a lens, and is applied to a shooting module applied to an adjustable lens or a lens group. The method comprises the following steps: A, according to imaging information of an adjusted optical system, determining parameters needing to be adjusted for compensating the imaging quality; B, establishing a relation function between the parameters needing to be adjusted for compensating the imaging quality and an adjusted-lens factor; and C, through a relation between the parameters needing to be adjusted for compensating the imaging quality and the adjusted-lens factor, determining an adjustment mode and an adjustment amount of an adjusted lens. According to the invention, accurate adjustment can be performed through an optical method in the assembling production process of a shooting module, the adjustment precision is high, the efficiency is high, the production demands for high quality, low cost and high efficiency can be satisfied, and the imaging quality of the optical system is improved.

Description

Technical field [0001] The present invention relates to the field of optical system imaging, and in particular to a method for compensating the imaging quality of the optical system by adjusting lenses or lenses. Background technique [0002] With the development of contemporary camera modules, module production is the assembly of main components such as chips and lenses. The quality of the lens itself and its cooperation with the module are the main factors that determine the imaging quality of the optical system. Under the current production mode , By controlling the quality of the lens, the tolerances of the main components, and the module assembly tolerance, a certain imaging quality can be achieved. The lens and the module are usually produced by controlling the tolerance of each part, that is, the method of assembly accuracy, and then the production inspection To ensure the image quality, this method has very high requirements for parts and assembly, and the image quality o...
