Problems solved by technology
There is no device dedicated to detecting mobile phone flashes in the existing market. Although there are related flash test devices on the market, because such devices require an external trigger switch to monitor the instantaneous light intensity signal, and today's Smartphone trigger camera functions are mostly triggered by the touch screen instead of external buttons, so during the test, the existing flash test equipment cannot be used to test the flash of the mobile phone

The invention discloses a mobile phone flash lamp multipath transient luminosity test system. The system comprises a light intensity detector, a luminosity tester and a computer host. The light intensity detector comprises a detector signal processing module and at least nine illumination photometers arranged at the illumination side of a mobile phone flash lamp. The luminosity tester comprises a high-speed data acquisition module and a tester low-light signal processing module. The illumination photometers, the detector signal processing module, the high-speed data acquisition module, the tester low-light signal processing module and the computer host are successively connected. The system can rapidly and accurately determine correct mobile phone initial flash lamp signals, solves the problem of illumination acquisition at the instant when a mobile phone is triggered, and acquires instant light intensity at multiple positions for determining the instant light intensity of the mobile phone flash lamp and whether the uniformity of instant illumination reaches a shooting requirement. A wireless communication mode is employed, the structure is simplified, and the distance between the light intensity detector and the luminosity tester is not restricted.
Description
technical field [0001] The invention relates to a multi-channel transient photometric testing system for mobile phone flash lamps. Background technique [0002] Smart phones on the market are usually provided with cameras for taking pictures and video recordings, and flashlights are provided with the cameras. When shooting at night or in environments with insufficient light, the flash can play a very good supplementary light effect. If you want to take clear and beautiful night scenes, you have high requirements for the instantaneous light intensity and the uniformity of the flash of the mobile phone. Therefore, In the process of designing a mobile phone, it is necessary to test the flash of the mobile phone to determine whether the instantaneous light intensity and the uniformity of the flash of the mobile phone meet the shooting requirements. There is no device dedicated to detecting mobile phone flashes in the existing market. Although there are related flash test device...
