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 present invention discloses an infrared light source component control method and an electronic device. An iris recognition module comprises an infrared light source module and an infrared camera, and the infrared light source module comprises at least two groups of infrared light sources with different working wavelengths. The control method comprises: turning on infrared light sources in turn; acquiring an iris image corresponding to each infrared light source by using an infrared camera; processing the iris image to acquire definition of the iris image; and turning on the infrared light source corresponding to the iris image with the highest definition according to definition and turning off the other infrared light sources. According to the control method and the electronic device provided by the present invention, the at least two groups of infrared light sources with different wavelengths are set and turned on in turn to select one group of infrared light sources with the best iris recognition effect for iris recognition; and thus, on the one hand, the iris recognition module can be applicable for more user groups so that applicability of the iris recognition module is increased, and on the other hand, the infrared light source with the best effect is selected, so that the efficiency of iris recognition 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...
