Title:
CORRECTION DEVICE FOR CAMERA MODULE OPTICAL IMAGE STABILIZER SYSTEM AND CORRECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/054689
Kind Code:
A1
Abstract:
A correction device for a camera module optical image stabilizer system and a method therefor. According to the method, a standard CTF plate is used to perform an MTF test, a parameter of an optical image stabilizer system is selected and obtained by balancing MTF resolution levels of a central view field and an edge field, and then an SFR test or a DB test can be used to evaluate an image stabilizer performance of the optical image stabilizer system. In this way, on the condition that the central resolution satisfies requirements, edge resolution is improved and edge image blurring phenomena are reduced, thereby balancing the overall picture quality of an image.
