The embodiments of the present invention will be described below with reference to the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a mobile terminal 100 according to an embodiment of the present invention. The mobile terminal 100 includes: a casing, a touch display screen, a main board, a battery and a sub board. The main board is provided with a front panel. Camera 21, processor 110, memory 120, ambient light sensor 130, breathing light 140, Subscriber Identity Module (SIM) card slot, etc. The sub-board is provided with a vibrator, an integrated sound cavity and a VOOC flash charging interface.

The image collector involved in this embodiment of the present invention may include the above-mentioned front camera 21, which is not limited here. For details, refer to the camera configured in the mobile terminal 100. The default is the front camera 21, and a rear camera or a rotating camera may also be used. . Image acquisition through a variety of cameras improves the convenience of operation and the flexibility of unlocking.

Based on the mobile terminal 100 described in FIG. 1, the following operations can be performed:

In this embodiment of the present invention, the ambient light sensor 130 may be located at the upper right of the mobile terminal 100 and to the left of the front camera 21, and is used to acquire ambient light intensity.

The ambient light intensity refers to the degree of light received by a luminous source such as natural light, lighting, or candle light on the surface of the target face in the shooting environment where the mobile terminal 100 is located, which is proportional to the luminous intensity of the luminous source and inversely proportional to the square of the distance. , the illuminance on the oblique plane is also related to the cosine function of the incident angle of the light. Unit Lux (Lux or Lx), that is, when the luminous flux obtained in 1 square meter area is 1 lumen, the ambient light intensity is 1 Lux.

In this embodiment of the present invention, the memory 120 is used to store the first threshold.

The first threshold is used to determine whether the breathing light 140 needs to be activated for supplementary light. When the ambient light intensity is less than the first threshold, the breathing light 140 can be turned on for supplementary light; and when the ambient light intensity is greater than or equal to the first threshold, The image collector can use the ambient light intensity or the brightness of the touch display screen to collect the target face image, thereby saving the power consumption of the mobile terminal 100 .

In this embodiment of the present invention, the processor 110 is configured to determine the first flickering parameter of the breathing light 140 according to the ambient light intensity when the ambient light intensity is less than the first threshold.

The first flickering parameter includes multiple dimension information, which may be flickering brightness, flickering color, flickering frequency, and the like. That is to say, when the ambient light intensity is less than the first threshold, the processor 110 determines the first flickering parameter corresponding to the ambient light intensity according to comprehensive factors such as the actual power of the breathing light 140, the actual usage, the adjustable range, and the loss, and the like, and The notification breathing light 140 is activated according to the first blinking parameter.

Optionally, the memory 120 is further configured to store historical unlocking records; in that the processor 110 determines the first flickering parameter of the breathing light according to the ambient light intensity, the processor 110 is specifically configured to The unlocking record obtains a light intensity threshold; obtains the difference between the light intensity threshold and the ambient light intensity to obtain a first supplementary light intensity value; and determines the first flickering parameter according to the first supplementary light intensity value.

Among them, the historical unlocking record includes the ambient light intensity when the unlocking is successful, the unlocking time, the quality parameters of the target face image (for example, the face offset angle, the degree of occlusion, the light quality parameters, etc.), the unlocking success rate, and so on. This embodiment of the present invention does not limit how to obtain the light intensity threshold according to the historical unlocking record, and can be based on the ambient light intensity, unlocking time, light quality parameters of the target face image, unlocking success rate, etc. included in the historical unlocking record in each dimension. The relationship between the corresponding parameter and the light intensity determines the light intensity threshold.

The first supplementary light intensity value is the light intensity value of the supplementary light required for face recognition under the current ambient light intensity. After the light intensity threshold is determined, the first supplementary light intensity value can be obtained according to the difference between the light intensity threshold and the ambient light intensity, and the first flickering parameter is determined according to the first supplementary light intensity value. When a flickering parameter is activated, the first fill light intensity value can be satisfied, thereby improving the recognition rate of face information.

Optionally, the memory 120 is further configured to store the mapping relationship between the supplementary light intensity value and the flickering parameter; in the aspect that the processor 110 determines the first flickering parameter according to the first supplementary light intensity value, the The processor 110 is specifically configured to search for the first flickering parameter corresponding to the first supplementary light intensity value according to the mapping relationship.

The processor 110 can obtain multiple sets of flickering parameters according to the adjustable range of the breathing light 140, and test each set of flickering parameters under different ambient light intensities to obtain the fill light intensity value corresponding to the set of flicker parameters, and obtain the fill light intensity. The mapping relationship between the value and the flickering parameter is stored in the memory 120 . After determining the first supplementary light intensity value, the processor 110 may search for the first flickering parameter corresponding to the first supplementary light intensity value according to the mapping relationship stored in the memory 120, thereby improving search efficiency and supplementary light accuracy.

For example, as shown in the mapping relationship between the fill light intensity value and the flicker parameter shown in Table 1, assuming that the first fill light intensity value is 20 lux, the flicker frequency in the first flicker parameter can be known by looking up the table: 2 Hz, Blinking Color: Yellow, Blinking Brightness: 20 Candela.

Table 1

In the embodiment of the present invention, the breathing light 140 is used to fill light on the human face according to the first flickering parameter.

Optionally, the processor 110 is further configured to acquire a working parameter corresponding to the first flickering parameter; in terms of the breathing light 140 filling light on the face according to the first flickering parameter, the breathing light 140 It is specifically used to fill light on the face according to the working parameter.

The working parameters may include voltage, current, power consumption, etc. After the processor 110 determines the first flickering parameter, the specific working parameter is determined according to the first flickering parameter and the actual power, actual usage, and consumption of the breathing light 140 , the mobile terminal 100 can allocate the above-mentioned working parameters, and then activate the breathing light 140 according to the working parameters to perform supplementary light for face recognition, thereby improving the supplementary light efficiency.

It can be seen that, in this embodiment of the present invention, the ambient light sensor obtains the ambient light intensity, and when the ambient light intensity is less than the first threshold, the processor determines the first flickering parameter of the breathing light according to the ambient light intensity, and notifies the breathing light to follow the first Flash parameters to start. That is to say, when the ambient light intensity is weak, the breathing lamp is used to fill light on the face, which improves the recognition rate of the face information when the ambient light intensity is weak.

Optionally, the memory 120 is further configured to store a second threshold value; the processor 110 is further configured to determine the shooting parameter corresponding to the first flickering parameter; obtain the light quality parameter of the target face image; When the light quality parameter is less than the second threshold, determine the second flickering parameter of the breathing light; the image collector is used to acquire the target face image according to the shooting parameters; the breathing light 140 is also used to When the light quality parameter is less than the second threshold, the first flickering parameter is adjusted to the second flickering parameter.

The acquisition can improve the acquisition effect of the target face image, thereby improving the recognition rate of the face information.

Among them, the light quality parameter is related to the recognition rate of the target face image. When the light quality parameter is high, the recognition rate is high. On the contrary, the lower the light quality parameter is, the lower the recognition rate is; the second fill light intensity value corresponding to the second flicker parameter Greater than the first fill light intensity value; the second threshold value is used to judge whether to enhance the fill light intensity, that is to say, if the light quality parameter of the target face image collected by the image collector is less than the second threshold value, it is necessary to re-determine the value of the breathing lamp 140. The flickering parameter, when the breathing light 140 works according to the second flickering parameter, can increase the intensity of the ambient light, thereby obtaining a target face image with a higher light quality parameter.

The second flickering parameter is similar to the first flickering parameter, and includes multiple dimensional information, which may be flickering brightness, flickering color, flickering frequency, and the like. For the specific method of adjusting the first flickering parameter to the second flickering parameter by the breathing light 140, reference may be made to the steps of the first flickering parameter, which will not be repeated here.

This embodiment of the present invention does not limit the second flickering parameter. When the light quality parameter is less than the second threshold, the second flickering parameter can be adjusted continuously, and the flickering parameter is supplemented according to the supplementary light intensity value from small to large, so as to avoid a From the beginning, the flickering parameter of the maximum fill light intensity value is used to fill light, which leads to a waste of power of the mobile terminal, and when the light quality parameter is greater than the second threshold, the target face image and the preset face image collected by the image collector are used. The matching value is used to unlock control, which improves the recognition rate of face information and the success rate of unlocking when the ambient light intensity is weak.

Optionally, the processor 110 obtains a matching threshold corresponding to the light quality parameter when the light quality parameter is less than the second threshold; when the matching value between the target face image and the preset face image is greater than the matching Unlock when the threshold is reached.

That is to say, if the light quality parameter of the target face image collected by the image collector is smaller than the second threshold, the processor 110 may determine the matching threshold for face recognition according to the light quality parameter, and determine the matching threshold between the target face image and the preset face When the matching value of the image is greater than the matching threshold, the mobile terminal is unlocked. That is, when the light intensity of the external supplementary light cannot perform face recognition, the matching threshold of face recognition is lowered, an unlocking method is provided, and the unlocking flexibility is provided.

That is to say, when the ambient light intensity is weak, the breathing lamp is used to fill light on the face, which improves the recognition rate of the face information when the ambient light intensity is weak.
