Abstract

The embodiment of the invention discloses a method and a device for detecting a flashlight module. The flashlight module detection method obtains the pixel point parameter information corresponding to each flashlight in the image information of the flashlight module, and then judges whether the pixel point parameter information satisfies the preset condition, and if the condition is met, then determines the pixel point information corresponding to The flashlight is the target flashlight in the flashlight module, and the detection result is generated according to the image position of the target flashlight. This solution conducts batch inspection on the flash lamps before installation, which can improve the speed of inspection and the accuracy of inspection results, and reduce the overall maintenance cost.

Description

technical field [0001] The present invention relates to the field of terminal technology, in particular to a method and device for detecting a flashlight module. Background technique [0002] Smart terminals are often equipped with a dual-color temperature flash to assist the camera in taking pictures. Current flashlights are generally LED (Light Emitting Diode, light emitting diode) lights. Due to the special material of the LED, the soldering temperature and assembly process will lead to changes in its color temperature and performance. For example, if the soldering temperature is too high, the LED will be damaged, and if the soldering time is too long, the LED luminous efficiency will be reduced and the color temperature will drift. [0003] At present, there is only control when the lamp beads leave the factory, but there is no inspection process after welding and assembly in the module factory. After this abnormal module is assembled to the terminal, although the cali...
