Abstract

The embodiment of the present invention provides a camera module glare test method, including the following steps: sending the camera module to the front of the LED light source screen; lighting up the LED lamp beads on the LED light source screen one by one according to the specified color temperature; A photo of the glare when the LED lamp bead is lit; according to the obtained photo, analyze and calculate the glare value of each test angle formed between the camera module and each LED lamp bead. On the other hand, the embodiment of the present invention also provides a camera module glare testing device. In the embodiment of the present invention, the photos of the glare situation when each LED lamp bead is lit can be automatically obtained, and the glare value can be analyzed and calculated according to the obtained photos, and the test efficiency is high; One-to-one correspondence of camera modules forms different test angles, breaking the limitation of a single test angle, making the test more comprehensive and complete, and not affected by human factors, making the test more accurate and objective.

Description

Technical field: [0001] The invention relates to a method and device for detecting glare of electronic products in the field of light, in particular to a method and device for detecting glare of a camera module. Background technique: [0002] Glare refers to the inappropriate brightness distribution in the field of vision, or the extreme brightness contrast in space and time, which causes visual discomfort and reduces the visibility of objects. Glare is one of the important causes of visual fatigue, which seriously affects driving or outdoor sports, and is extremely dangerous. [0003] As the safety performance of automobiles has attracted more and more attention, the active safety system of automobiles has become the focus of public attention. Advanced Driver Assistance Systems, referred to as ADAS, use various sensors installed on the The environmental data inside and outside the car is processed technically such as identification, detection and tracking of static and dyn...
