[0002] In pursuit of a higher screen-to-body ratio, an in-screen optical fingerprint solution has emerged. In related technologies, there is a fixed pressing area on the display screen of an electronic device. The pressing area can display a fingerprint light spot. When a user uses the in-screen fingerprint, by pressing the area with a finger, the fingerprint light spot corresponding to the area is lit to a pre-set brightness, such as 600 nit (a brightness unit, nit), to light up the fingerprint part, thereby realizing fingerprint collection.

[0003] During the process of a user using the in-screen fingerprint, there may be a problem of light leakage of the light spot due to incomplete pressing of the above area by the finger. And the sensitivity of the user to the screen brightness is different in different environments. Especially in dim light scenarios such as evening, night, and cinema, the human eye is more sensitive to light.

[0027] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] It should be noted that all actions of obtaining signals, information, or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located and obtaining the authorization given by the owner of the corresponding device.

[0029] In order to pursue a higher screen-to-body ratio, the under-screen optical fingerprint solution has emerged. In the related art, there is a fixed pressing area on the display screen of the electronic device. The pressing area can display a fingerprint spot. When the user uses the under-screen fingerprint, by pressing the area with a finger, the fingerprint spot corresponding to the area is lit to a pre-set brightness, for example, 600 nit, to light up the fingerprint part, thereby realizing the collection of the fingerprint.

[0030] During the process of the user using the under-screen fingerprint, there may be a problem of light leakage of the spot due to incomplete finger pressing of the above area. For example, as Figure 1 shown, the user presses the elliptical pressing area on the electronic device incompletely, resulting in light leakage of the fingerprint spot in the elliptical area. And the user's sensitivity to the screen brightness is different in different environments. Especially in dim light scenarios such as evening, night, and cinema, the human eye is more sensitive to light. In such scenarios, if light leakage occurs, the pre-set brightness may cause the user to feel dazzling in such scenarios, directly affecting the unlocking experience in such scenarios. Or, in a brighter light scenario, compared with the ambient brightness, the pre-set brightness is too small, resulting in a low brightness of the collected fingerprint and few details included, which may directly affect the fingerprint recognition effect. In addition, if the pre-set brightness is set to be relatively large, then the display screen may have a risk of being burned out.

[0031] Based on this, the present disclosure provides a fingerprint spot brightness adjustment method. Refer to Figure 2 , the fingerprint spot brightness adjustment method can be applied to Figure 8 the fingerprint spot brightness adjustment device 200 shown in Figure 9The electronic device 800 and the computer-readable storage medium shown. In this embodiment, it is taken as an example of being applied to an electronic device. For example, the electronic device can be a device with a display screen such as a smart phone, a tablet computer, a wearable device, a vehicle-mounted device, a notebook computer, a super mobile personal computer, etc. The specific type of the electronic device is not limited in the embodiments of the present disclosure. The following will be directed to Figure 2 The process shown will be elaborated in detail. The fingerprint spot brightness adjustment method can specifically include the following steps:

[0032] Step S110: Detect the ambient brightness of the environment where the electronic device is located.

[0033] A sensor for detecting brightness is provided on the electronic device. The ambient brightness of the environment where the electronic device is located is detected through this sensor, and this ambient brightness can reflect the brightness and darkness of the environment where the electronic device is located. For example, the sensor for detecting brightness can be, but is not limited to, a photoresistor sensor, a photodiode sensor, etc.

[0034] In one implementation manner, the electronic device detects the ambient brightness of the environment where the electronic device is located in real time or periodically.

[0035] In another implementation manner, when a pressing operation on the electronic device is detected, the sensor on the electronic device works to detect the ambient brightness of the environment where the electronic device is located. Optionally, the pressing operation can be a pressing operation on any position on the display screen of the electronic device, or a pressing operation on a specific position on the electronic device, such as a pressing operation on a preset area where the fingerprint spot is located.

[0036] As a way, when a pressing operation on the preset area by the user is detected, if the pressing area is larger than the preset area and the trigger condition for ambient brightness detection is met, the ambient brightness of the environment where the electronic device is located is detected. For example, the preset area is 50%, 60%, etc. of the area of the preset area.

[0037] Step S120: Determine the display brightness of the fingerprint spot according to the ambient brightness.

[0038] According to the ambient brightness, determine the display brightness of the fingerprint spot adapted to this ambient brightness.

[0039] Step S130: Control the light-emitting unit provided inside the electronic device to light up the fingerprint spot displayed on the electronic device at a first brightness during a first period of a preset period, and control the light-emitting unit to light up the fingerprint spot at a second brightness during a second period of the preset period, so that the fingerprint spot is displayed at the display brightness during the preset period.

[0040] The light-emitting unit of the electronic device is arranged inside the electronic device, and is oppositely arranged with a preset area on the display screen of the electronic device where a fingerprint light spot is displayed. When the light-emitting unit is lit, it illuminates the fingerprint light spot, so that the fingerprint light spot can be displayed on the display screen. The fingerprint light spot illuminates the user's fingerprint with a display brightness, which is convenient for the electronic device to collect the user's fingerprint information for subsequent fingerprint recognition.

[0041] Among them, the preset period is less than the minimum duration that the human eye can perceive. The preset period includes a first period and a second period, and both the first period and the second period are longer than the time for the electronic device to collect an image once. This embodiment adjusts the brightness of the fingerprint light spot using the principle of PWM (Pulse Width Modulation) dimming, that is, the electronic device controls the light-emitting unit to light up the fingerprint light spot with a first brightness during the first period, and controls the light-emitting unit to light up the fingerprint light spot with a second brightness during the second period. Since the preset period is less than the minimum duration that the human eye can perceive, within the preset period, even if the brightness displayed in the preset area changes, the human eye will not feel the light-emitting unit flickering, but can only see the display brightness superimposed by the first brightness and the second brightness, thereby realizing the adjustment of the display brightness of the fingerprint light spot.

[0042] Optionally, the display brightness of the fingerprint light spot can be adjusted by adjusting the first brightness, the second brightness, the first period, and the second period. For example, the display brightness can be adjusted by adjusting the ratio of the first period to the second period. As Figure 3 shown, the duration of the preset period is t2, where t1=(1 / 2)*t2, and the display brightness is (n1 + n2) / 2, where n1 is at least the lowest brightness that the display screen can display, and n2 is at most the highest brightness that the display screen can display. As Figure 4 shown, the duration of the preset period is t5, where t4=(3 / 4)*t5, and the display brightness is (3*n1 + n2) / 4. In addition to adjusting the ratio of the first period to the second period in the preset period, the first brightness and the second brightness can also be adjusted. As Figure 5 shown, the duration of the preset period is t7, where t6=(1 / 2)*t7, and the display brightness is (n3 + n4) / 2.

[0043] It should be noted that if the first period is not an integer multiple of the time for the electronic device to collect an image once, then the number of times of collecting fingerprint images during the first period is the integer obtained by dividing the first period by the time for collecting an image once, which can avoid the electronic device collecting images with brightness changes at the junction of the first period and the second period, thereby affecting the clarity of the collected fingerprint images.

[0044] The fingerprint spot brightness adjustment method provided by the present disclosure detects the ambient brightness of the electronic device, then determines the display brightness adapted to the ambient brightness according to the ambient brightness, and then controls the light-emitting unit arranged inside the electronic device to light up the fingerprint spot displayed on the electronic device at a first brightness during the first period of a preset period, and controls the light-emitting unit to light up the fingerprint spot at a second brightness during the second period of the preset period, so that the fingerprint spot is displayed at the display brightness within the preset period. The present disclosure adapts the display brightness according to the ambient brightness, and adapts a relatively dim display brightness in a dark environment. Even if there is light leakage, this display brightness will not cause a dazzling feeling to the user. In a bright environment, a relatively bright display brightness is adapted, and the user's fingerprint is illuminated by the relatively bright display brightness, so that the brightness of the fingerprint collected in the bright environment is high and contains a lot of details, so as to improve the accuracy of subsequent fingerprint recognition. In addition, compared with the method of setting a certain fixed brightness in the related art, in the present disclosure, the display brightness is adapted according to the ambient brightness, and then the display brightness of the fingerprint spot is flexibly adjusted by using the principle of PWM dimming, which can save the energy consumption of the electronic device. In addition, the risk of burning out caused by the display of a high-brightness fingerprint spot on the display screen all the time can also be reduced.

[0045] In one implementation manner, step S120 may be as follows: Obtain the screen brightness of the display screen. For example, obtain the screen brightness of the display screen through a sensor, or obtain the parameter corresponding to the screen brightness, and obtain the screen brightness according to this parameter. Then, according to the ambient brightness and the screen brightness, determine the display brightness of the fingerprint spot. For example, if the screen brightness is 0, it indicates that the display screen of the electronic device is in the off-screen state. It can be understood that when the user directly presses the preset area where the fingerprint spot is located, the first correspondence relationship between the ambient brightness and the display brightness is determined, and according to this first correspondence relationship, the display brightness corresponding to the ambient brightness is determined. If the screen brightness is not 0, it indicates that the display screen of the electronic device is in the on-screen state. It can be understood that when the user first lights up the screen by pressing a preset button on the electronic device or touching any position on the display screen of the electronic device except the preset area, the second correspondence relationship between the ambient brightness and the display brightness is determined, and according to this second correspondence relationship, the display brightness corresponding to the ambient brightness is determined. Optionally, at the same ambient brightness, the display brightness determined by the first correspondence relationship is lower than the display brightness determined by the second correspondence relationship.

[0046] For ease of understanding, taking the above correspondence relationship as an example of a relationship curve for illustration, please refer to Figure 6, Curve L2 is a curve between the ambient brightness and the brightness of the display screen. It can be understood that the electronic device can utilize Curve L2 to adapt the brightness of the display screen according to the ambient brightness. When the screen brightness is not 0, Curve L1 above Curve L2 is determined. Among them, the abscissa of Curve L1 corresponds to the ambient brightness, and the ordinate corresponds to the display brightness. The display brightness corresponding to the ambient brightness is obtained through Curve L1. When the screen brightness is 0, Curve L3 below Curve L2 is determined. Among them, the abscissa of Curve L3 corresponds to the ambient brightness, and the ordinate corresponds to the display brightness. The display brightness corresponding to the ambient brightness is obtained through Curve L3.

[0047] In this embodiment, when the ambient brightness is the same, when the screen brightness is not 0, the obtained display brightness is relatively high, which can enable the electronic device to collect fingerprints that are clear enough to improve the accuracy of subsequent fingerprint recognition. When the screen brightness is 0, the obtained display brightness is relatively low. This display brightness is sufficient to illuminate the user's fingerprint, enabling the electronic device to collect clear fingerprints to improve the accuracy of subsequent fingerprint recognition. In addition, this relatively low display brightness can reduce the power consumption of the electronic device.

[0048] Optionally, when the screen brightness is not 0, the brightness of the fingerprint light spot can be greater than the brightness of the screen to increase the contrast and clarity of the collected fingerprint image.

[0049] It should be noted that when the screen brightness is 0, the brightness of any fingerprint light spot can be greater than the screen brightness. Therefore, when the screen brightness is 0, the curve between the ambient brightness and the display brightness is not limited to the above-mentioned Curve L3, and can also be Curve L1 or Curve L2.

[0050] In another embodiment, the brightness interval in which the ambient brightness is located is determined. For example, Figure 7 in Curve L3, according to the change of Curve L3, the brightness interval is divided into a first interval, a second interval, and a third interval. Among them, the display brightness in both the first interval and the third interval is a fixed value. In the second interval, there is a positive correlation between the ambient brightness and the display brightness. According to the preset mapping relationship corresponding to the brightness interval and the ambient brightness, the display brightness of the fingerprint light spot is determined, where the preset mapping relationship includes the corresponding relationship between the ambient brightness and the display brightness.

[0051] In one embodiment, step S110 may be to detect the ambient brightness of the environment where the electronic device is located when a pressing operation on the preset area where the fingerprint light spot is located is detected.

[0052] The method for adjusting the brightness of the fingerprint light spot further includes: identifying the fingerprint pressing on the preset area to obtain an identification result; if the identification result does not match the preset result, adjusting the display brightness, where the preset result corresponds to the fingerprint entered by the user stored in the electronic device; controlling the light emitting unit to light up the fingerprint light spot at the first brightness during the third period within the preset period, and controlling the light emitting unit to light up the fingerprint light spot at the second brightness during the fourth period of the preset period, so that the fingerprint light spot is displayed at the adjusted display brightness within the preset period.

[0053] Optionally, the adjusted display brightness is the preset maximum brightness.

[0054] Optionally, the display brightness can also be gradually adjusted to the preset maximum brightness through multiple adjustments. For example, if the new identification result does not match the preset result, the display brightness is readjusted until the number of adjustment times reaches the preset number of times, and then the display brightness is adjusted to the preset maximum brightness.

[0055] After the light spot brightness is displayed on the electronic device according to the display brightness, a fingerprint image is collected. After repeatedly adjusting the display brightness for the preset number of times, the fingerprint images collected for the preset number of times are combined for fingerprint identification, thereby improving the accuracy of fingerprint identification. For example, a fingerprint recognition algorithm is used to identify the fingerprint image.

[0056] Optionally, after adjusting the preset number of times, if the collected identification result still does not match the preset result, an interface corresponding to other unlocking methods is displayed on the display screen. For example, an interface corresponding to face unlocking or an interface corresponding to password unlocking is displayed.

[0057] Optionally, the fingerprint light spot is controlled to be displayed according to preset parameters, where the preset parameters corresponding to the fingerprint light spots with different display brightnesses are the same or different.

[0058] For example, the preset parameters include photoelectric conversion efficiency, effective light receiving area of pixels, preset period, etc.

[0059] Setting the preset parameters to be the same can reduce the number of parameters stored in the electronic device and can correspondingly reduce the occupation of computing resources and storage resources. Setting the preset parameters to be different makes the preset parameters more adaptable to various display brightnesses, so that better fingerprints can be collected, and thus the accuracy of subsequent fingerprint identification can be improved.

[0098] In summary, the present disclosure provides a method, apparatus, electronic device, and medium for adjusting the brightness of a fingerprint light spot. First, the ambient brightness of the environment where the electronic device is located is detected, then the display brightness adapted to the ambient brightness is determined according to the ambient brightness, and then the light-emitting unit provided inside the electronic device is controlled to light up the fingerprint light spot displayed on the electronic device at a first brightness during a first period of a preset cycle, and the light-emitting unit is controlled to light up the fingerprint light spot at a second brightness during a second period of the preset cycle, so that the fingerprint light spot is displayed at the display brightness within the preset cycle. The present disclosure adapts the display brightness according to the ambient brightness, and adapts a relatively dim display brightness in a dark environment. Even if there is light leakage, this display brightness will not cause a dazzling feeling to the user. In a bright environment, a relatively bright display brightness is adapted, and the user's fingerprint is illuminated by the relatively bright display brightness, so that the brightness of the fingerprint collected in the bright environment is high and contains a lot of details, so as to improve the accuracy of subsequent fingerprint recognition. In addition, compared with the method of setting a certain fixed brightness in the related art, in the present disclosure, the display brightness is adapted according to the ambient brightness, and then the PWM dimming principle is used to flexibly adjust the display brightness of the fingerprint light spot, which can save the energy consumption of the electronic device.
