CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national phase of International Application No. PCT/CN2018/090625 filed on Jun. 11, 2018, which claims priority and benefit to Chinese Patent Application No. 201710552517.5 filed on Jul. 7, 2017. The disclosures of these applications are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

The disclosure relates to electronic devices, and more particularly to a control method, an electronic device and a computer-readable storage medium.

BACKGROUND

Iris recognition generally requires an infrared light source to assist an infrared camera to acquire a clear iris image. However, an illumination range of the infrared light source is limited, which results in a limited working range for the iris recognition.

SUMMARY

The embodiments of the disclosure provide a control method, an electronic device and a computer-readable storage medium.

A control method for an infrared light source assembly according to the embodiments of the disclosure may be used in an electronic device. The electronic device may include a camera. The infrared light source assembly may include at least two infrared light sources having different illumination ranges. The control method may include the following operations.

The camera is controlled to acquire an image of a face.

The image of the face is processed to obtain position information of the face.
