Embodiment Construction

[0035] As mentioned in the background art, the test results of the resolution of the camera module in the prior art are relatively single, and the resolution performance of the camera module cannot be tested comprehensively.

[0036] In view of this, an embodiment of the present application provides a method for detecting the resolution of a camera module, the camera module includes a processing chip, and the method for detecting the resolution of the camera module includes:

[0037] The camera module is arranged in the temperature and humidity control box, the lens of the camera module is facing the perspective window of the temperature and humidity control box;

[0038] The teleconverter is arranged on one side of the temperature and humidity control box, and is aligned with the lens of the camera module;

[0039] Set the target paper on the side of the teleconverter away from the camera module, and adjust the distance between the camera module lens and the teleconverter and...

Abstract

The invention discloses a method and system for detecting the resolving power of a camera shooting module. When the method for detecting the resolving power of the camera shooting module is used for conducting the resolving power test on the camera shooting module, firstly, the camera shooting module is arranged in a temperature and humidity control box; then, a teleconverter is arranged, and the distance between the teleconverter, the camera shooting module and the temperature and humidity control box is adjusted so that test requirements can be met; finally, the camera shooting module is controlled to start working, environmental parameters in the camera shooting module are controlled through the temperature and humidity control box, target sheet images shot by the camera shooting module under different environmental parameters are acquired through a processing chip of the camera shooting module, and the target sheet images are analyzed to acquire resolving power parameters of the camera shooting module under different environmental parameters. The method for detecting the resolving power of the camera shooting module solves the problems that in the prior art, the detection result of the resolving power test on the camera shooting module is singular, and the resolving power performance of the camera shooting module can not be comprehensibly detected.

Description

technical field [0001] The invention relates to the technical field of camera module detection, and more specifically, to a method and system for detecting resolution of a camera module. Background technique [0002] The resolution refers to the ability of the camera module to distinguish the details of the original object. In the prior art, the equipment for testing the resolution of the camera includes a target paper and a decoding tool. When the camera module is tested, the decoding tool is first connected to the camera module; Then select a suitable test distance, use the camera module to aim at the target paper and shoot; finally, after the decoding tooling displays the target paper image taken by the camera module, the tester reads the resolvable lines in the target paper image. The number of pairs indicates the resolution of the camera module. [0003] Before the camera module leaves the factory, the resolution of the camera module will be tested before and after the...
