Problems solved by technology
[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 an infrared light source assembly control method and an electronic device. The electronic device comprises an iris identification module and a visible light camera, wherein the iris identification module comprises an infrared light source assembly, the infrared light source assembly comprises at least two infrared light sources, and work wavelengths of the at least two infrared light sources are different. The control method comprises steps that a face image is acquired through the visible light camera; the race information is acquired according to the face image; one of the at least two infrared light sources is started according to the race information. Through the control method and the electronic device, through combination of the visible light camera and the iris identification module, the race information is identified through the visible light camera before iris identification, the infrared light source with the corresponding wavelength in the iris identification module is started according to the race information to carry out iris identification, for users of different races, the infrared light sources with the different work wavelengths are started, on one hand, applicability of the iris identification module is enhanced, on the other hand, iris identification efficiency is improved.
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...
