Abstract
The present disclosure discloses a method for compensating for image quality of an optical system by means of a lens adjustment, applicable to a camera module comprising an adjustable lens or an adjustable lens set, the method comprising the following steps: (A) determining, based on imaging information of a to-be-adjusted optical system, parameters that need to be adjusted for compensating for the image quality; (B) establishing functions of relation between the parameters that need to be adjusted for compensating for the image quality and a to-be-adjusted lens factors; and (C) determining an adjustment mode and an adjustment amount for the to-be-adjusted lens based on the relation between the parameters that need to be adjusted for compensating for the image quality and the to-be-adjusted lens factors. Whereby, the present disclosure implements the accurate adjustment of the camera module by using an optical method during assembly and production, has high adjustment precision and high efficiency, can meet the production requirements such as high quality, low costs and high efficiency, and improves the image quality of the optical system.
