Embodiment Construction

[0030] The invention provides a face unlocking method in a dark state and a mobile terminal thereof, which are applicable to various mobile terminals with a Face ID function. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] see figure 1 , the face unlocking method in the dark state of an embodiment provided by the present invention includes:

[0032] S100. When detecting the start of face unlocking, obtain the ambient brightness and judge whether it is currently in a dark state according to the ambient brightness. If it is, perform step S200. If not, collect face data and perform face unlocking;

[0033] S200. After adjusting the brightn...

Abstract

The present invention discloses a face unlocking method in a dark state and a mobile terminal thereof. The face unlocking method includes: A. detecting when the face unlocking starts, acquiring ambient brightness and judging whether it is currently in a dark state according to the ambient brightness, If yes, perform step B, if not, collect face data and perform face unlocking; B, adjust the backlight brightness of the screen to the maximum value, collect face data, and perform face unlocking based on the face data. The way of screen fill light is used to increase the brightness of the environment. By illuminating the face with the brightest backlight, the face gets more light, so the captured face will be clearer, which can improve the success rate of unlocking.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a face unlocking method in a dark state and a mobile terminal thereof. Background technique [0002] Face ID is a face authentication method introduced instead of Touch ID. Taking a mobile phone as an example, it only collects face data when unlocking, and does not take pictures; the collected face data is compared with the face data entered in the mobile phone through a preset algorithm, and if the two face data are consistent, the mobile phone is successfully unlocked. At present, the face data is usually collected by the front camera to realize the face unlocking function. However, in the dark state, the environment is relatively dark, and the collected face data is relatively blurred, resulting in a low unlocking success rate and affecting the user's unlocking effect. [0003] Thereby prior art still needs to improve and improve. Contents of the invention [0004] In ...
