Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions of each exemplary embodiment provided by the present invention with reference to the accompanying drawings in the embodiments of the present invention. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.
[0019] see figure 1 , is a test system for the illuminance of a flashlight according to an embodiment of the present invention. The testing system 10 includes a light intensity sensor 11 and a terminal to be tested 12 for testing the flashlight 121 of the terminal to be tested 12 . Wherein, between the terminal 12 to be tested and the light intensity sensor 11, I 2 C (Inter-Integrated Circuit, two-wire serial) bus to establish a connection, of course, the two can also establish a connection through wireless communication methods such as Bluetooth, Wi-Fi, and infrared radio frequency.
[0020] When the terminal 12 to be tested...

The invention discloses a test method and a test system for the illuminance of a terminal flash lamp. The method includes: establishing a connection between the terminal to be tested and the light intensity sensor; the light intensity sensor collects the light intensity signal of the flashlight of the terminal to be tested in a working process according to a preset frequency; the light intensity sensor simulates the light intensity signal Digital conversion, and send the light intensity signal after analog-to-digital conversion to the terminal to be tested; the terminal to be tested obtains the maximum value from the received light intensity signal, and uses it as the instantaneous light intensity of the flash. Based on this, the present invention can directly use the terminal to be tested and the light intensity sensor to complete the test of the flashlight, and can obtain the instantaneous light intensity of the flashlight with a relatively simple structure.
Description
technical field [0001] The invention relates to a test method and a test system for the illuminance of a terminal flash lamp. Background technique [0002] Currently, terminals such as smart phones on the market are usually provided with a camera for taking pictures, and a flashlight is provided with the camera. When shooting at night or in an environment with insufficient optical fibers, the flash can play a very good supplementary light effect, so the terminal has high requirements on the instantaneous light intensity of the flash. During the terminal design process, the manufacturer needs to test the flash to ensure Determine whether the instantaneous light intensity of the mobile phone flash meets the shooting requirements. There is no device dedicated to detecting the flashlight of mobile phones in the existing market, but the light intensity of the flashlight in the flashlight lighting mode is collected by equipment such as an illuminance meter, and it is difficult to...
