[0023] The method for detecting the performance of the lens module provided by the present invention will be described in further detail below with reference to the accompanying drawings.
[0024] 1 to 3 together, the method 100 for detecting the performance of a lens module provided by the first embodiment of the present invention includes the following steps:
[0025] (1) A lens module 10 to be tested and a camera 20 for inspection are provided. The lens module 10 to be tested includes a lens barrel 11, and two lenses are assembled in the lens barrel 11 sequentially from the object side to the image side. 12, 13, and an aperture 14 sandwiched between the lenses 12, 13. The aperture 14 forms an entrance pupil 15 on the object side of the lens module 10 to be tested via the lens 12, and The lens 13 forms an exit pupil 16 on the image side of the lens module 10 to be tested;
[0026] (2) Using the detection camera 20 to photograph the lens barrel 11 and the exit pupil 16 of the len...
