Example Embodiment
[0018] The measuring device and measuring method of the modulation transfer function value of the technical scheme will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] See figure 2 , Which is the modulation transfer function value measuring device 200 provided by the first embodiment of the technical solution, which includes a test board 21, an image sensor 22, a carrying device 23, and a driving device 24. The modulation transfer function value measuring device 200 is used to measure the modulation transfer function value of the lens.
[0020] The test board 21 has multiple areas with different brightness, for ease of description, figure 2 A plurality of patterns 211 indicate areas of different brightness. For the needs of subsequent measurement, a first test area and a second test area are defined on the test board 21. Both the first test area and the second test area have multiple light and dark patterns 211. For ex...
