[0002] Iris recognition generally requires an infrared light source to assist the iris camera to obtain a clear iris image. Due to the different iris colors of different races, the applicable infrared light source has different wavelengths, and the applicability of a single-wavelength infrared light source is poor.
For this reason, multiple infrared light sources with different working wavelengths can be set, however, how to select and start the infrared light source corresponding to the working wavelength becomes a new problem

The invention discloses a control method and an electronic device for an infrared light source assembly. The electronic device includes an iris recognition module and a visible light camera, the iris recognition module includes an infrared light source assembly, the infrared light source assembly includes at least two infrared light sources, and the working wavelengths of the at least two infrared light sources are different. The control method includes the steps of: collecting a face image by a visible light camera; acquiring race information according to the face image; and starting one of at least two infrared light sources according to the race information. The control method and the electronic device of the embodiment of the present invention, through the cooperation of the visible light camera and the iris recognition module, identify the race information through the visible light camera before iris recognition, and start the infrared light source of the corresponding wavelength in the iris recognition module according to the race information For iris recognition, for users of different races, start infrared light sources with different working wavelengths. On the one hand, it increases the applicability of the iris recognition module, and on the other hand, it improves the efficiency of iris recognition.
Description
technical field [0001] The invention relates to the field of electronic devices, in particular to a method for controlling an infrared light source assembly and an electronic device. Background technique [0002] Iris recognition generally requires an infrared light source to assist the iris camera to obtain a clear iris image. Due to the different iris colors of different races, the applicable infrared light source has different wavelengths, and the applicability of a single-wavelength infrared light source is poor. To this end, multiple infrared light sources with different working wavelengths can be provided. However, how to select and activate the infrared light source corresponding to the working wavelength becomes a new problem. Contents of the invention [0003] Embodiments of the present invention provide a control method and an electronic device for an infrared light source assembly. [0004] The control method of the infrared light source assembly according to t...
