Camera module automatic testing system and camera module automatic testing method

Abstract

The invention relates to a camera module automatic testing system and a camera module automatic testing method. The automatic testing system comprises a test board, a control unit, a first driving unit and a focusing ring; the test board is used for fixing a to-be-tested camera; the to-be-tested camera transmits acquired data to the control unit through the test board; the first driving unit is connected with the focusing ring; the focusing ring is used for adjusting the focal distance of the to-be-tested camera; the first driving unit is used for driving the focusing ring to move; the control unit is used for receiving data, performing data processing and controlling the movement of the first driving unit and the focusing ring, thereby realizing automatic test of the to-be-tested camera; the automatic testing method realizes the automatic test of the camera by using the testing system. According to the camera module automatic testing system and the camera module automatic testing method, the camera testing process can be simplified remarkably, the camera testing accuracy can be improved, the working strength of the camera test can be reduced, and the cost is consequently reduced while the camera testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of camera testing, in particular to a camera module automatic testing system and an automatic testing method. Background technique [0002] The camera is a video input device, which is widely used in video conferencing, telemedicine and real-time monitoring. The performance of the camera has a great influence on the electronic equipment that depends on the camera. Therefore, the test of the camera is very important. [0003] The camera needs to test its various parameters during the production process, and when the lens detects a defect, it needs to be adjusted. However, in the prior art, there are many problems in testing various parameters of the camera: [0004] First of all, the degree of automation of the testing process is very low, relying heavily on manual testing. For example, most of the focusing and image testing of cameras are done manually. This non-automatic test method leads to low focusing accuracy,...

AI Technical Summary

Problems solved by technology

The single function of a single device and the inability to conduct a unified test of each parameter of the camera have greatly increased the number of lens installations and the investment in the number of devices, which has also caused many problems. One is that separate tests cannot realize the automation of the test, thus It greatly increases the labor intensity of the staff. The second is that the test process is too complicated, which increases the occurrence of inaccurate test results and cannot guarantee the reliability of the test results. Third, it greatly increases the cost burden of the enterprise.
