Abstract

The embodiment of the invention discloses an auto-focusing debug method, a device, an apparatus and a storage medium. The method comprises the following steps: obtaining an average position corresponding to a peak point of the definition of a sample product; obtaining an average position corresponding to a peak point of the definition of the sample product; determining a target test distance of the target product according to the average position and a standard value of the process capability index; Debugging the target product based on the target test distance to obtain a position corresponding to a peak point of clarity of the target product. The embodiment of the invention determines the specification range of the product satisfying the quality standard through the process capability index standard value related to the product quality in the production process, and takes the specification range as the test distance of the product, thereby realizing fast and accurate positioning, shortening the time of the product automatic focusing and debugging, and improving the debugging efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the field of optical technologies, and in particular, to an autofocus debugging method, device, equipment, and storage medium. Background technique [0002] With the wide application of the camera function of smart devices such as mobile phones, tablet computers and smart watches, in order to meet market requirements, it is necessary to test different functions of the camera module, such as auto focus detection. [0003] Autofocus is a technology that automatically focuses on the object to be photographed and obtains a clear image through electronic, mechanical and image processing means. The camera module makes its data within the specifications required by the customer through autofocus detection and debugging, so that the camera module of the mobile phone can quickly drive the voice coil motor (Voice Coil Actuator / Voice Coil Motor, VCM) to Find the position of the corresponding lens when the image is c...
