Fig. 1 schematically illustrates a block diagram of an intensity processing system for an off-screen fingerprint image according to an exemplary embodiment of the present disclosure. Referring to fig. 1, a brightness processing system 1 of an under-screen fingerprint image of an exemplary embodiment of the present disclosure may include a terminal device 11, a control device 12, and a brightness detection device 13.
The terminal device 11 may be a device having an off-screen fingerprint recognition function, including, for example, a mobile phone, a tablet computer, a smart watch, a smart bracelet, etc., and the type of the terminal device 11 is not particularly limited in the present disclosure.
The control device 12 may be a device for sending a control instruction to the terminal device 11 to control the terminal device to maintain the fingerprint image in a lit state, for example, the control device 12 may be a personal computer, a server, or the like, and in addition, the control device 12 may be another independent hardware processing unit, and the type of the control device 12 is not particularly limited in the present disclosure.
The brightness detection device 13 may be an instrument for measuring brightness, for example, an illuminometer.
Referring to fig. 1, data transmission is possible between a terminal device 11 and a control device 12. The brightness detection device 13 may directly act on the terminal device 11 in order to detect the brightness of the fingerprint image, for example, the brightness detection device 13 may be fixed by means of a bracket in a position where the brightness of the fingerprint image of the terminal device 11 can be detected, and the brightness detection device 13 may be turned on by a tester when the fingerprint image is lit. In addition, the control device 12 may control the luminance detection device 13, for example, send an on instruction to the luminance detection device 13 to turn on the luminance detection device 13.
The functions of the respective components of the brightness processing system of the under-screen fingerprint image according to the exemplary embodiment of the present disclosure will be described below with reference to fig. 2.
Referring to fig. 2, in step S202, the terminal device 11 may control the fingerprint image to be lit for a preset period of time in response to the brightness test trigger operation.
Specifically, the brightness test triggering operation may refer to an operation that a tester touches a fingerprint identification area of the terminal device with a finger, and may also refer to an operation that the fingerprint identification area is touched with an unreal test finger adopted in an experiment. However, any other scheme for simulating the fingerprint identification triggering operation by adopting a software or hardware control means belongs to the protection scope of the invention.
The fingerprint image may be a spot containing fingerprint information that the terminal device 11 lights up in response to a brightness test trigger operation. In addition, the preset time period may be an intrinsic parameter of the terminal device, and the value is often small.
In step S204, the control device 12 may transmit a state maintenance instruction to the terminal device 11 in response to the fingerprint brightness test event.
According to some embodiments of the present disclosure, the fingerprint brightness test event may include the control device 12 receiving an instruction brightness test instruction sent by the terminal device 11. In this case, the terminal device 11 may also generate a fingerprint brightness test instruction in response to the above-described brightness test triggering operation, and transmit the fingerprint brightness test instruction to the control device 12.
According to further embodiments of the present disclosure, the fingerprint brightness test event may also include a user entering a state maintenance command at the control device 12.
Taking the example of testing the brightness of the fingerprint image of the android mobile phone, the control device 12 may be a PC (Personal Computer ) terminal, and in the case that the ADB (Android Debug Bridge ) is connected, the user may input an ADB shell stop command in a command input window of the PC terminal, where the ADB shell stop command may maintain the running state of the current mobile phone desktop.
It should be appreciated that the brightness test triggering operation may occur concurrently with the fingerprint brightness test event, or the time difference between the two triggers may be less than the predetermined time period.
In step S206, the terminal device 11 may determine whether a state maintaining instruction is received within a preset period of time after the fingerprint image is lit, and if the state maintaining instruction is received, control the fingerprint image to maintain the lit state.

In step S208, the luminance of the fingerprint image may be detected by the luminance detecting apparatus 13 in a state where the fingerprint image remains lit.
Further, the control device 12 may also generate a state restoration instruction in response to an operation of the state restoration command input by the user, and transmit the state restoration instruction to the terminal device 11. After receiving the state restoration instruction, the terminal device 11 may restore the operation state of the terminal device 11.
Still taking the terminal device 11 as an android mobile phone and the control device 12 as a PC end as an example, the user may input an adb shell start command in a command input window of the PC end, where the adb shell start command may enable the mobile phone desktop to restart running.
In addition, the control device 12 may also send a state recovery instruction to the terminal device 11 by itself after a preset period of time after sending the state maintenance instruction. The preset duration may be a time sufficient to detect brightness, and may be obtained through several test tests, where specific values in the present exemplary embodiment are not particularly limited.
Still other embodiments of the present disclosure may further include a scheme for analyzing the brightness result obtained by the test to determine whether the brightness of the fingerprint image of the terminal device needs to be adjusted.
The control device 12 may acquire the test result from the brightness detection device 13 and determine whether to adjust the brightness of the fingerprint image of the terminal device 11 according to the test result. However, it should be understood that the brightness detection device 13 may also analyze the detected data by itself, and send an instruction for brightness adjustment to the control device 12 or directly to the terminal device 11 when brightness adjustment is required.
Specifically, the fingerprint image brightness detection process of steps S202 to S208 may be repeatedly performed, wherein the reset of each detection process may be performed by the control device 12 sending a state recovery instruction to the terminal device 11 to obtain a plurality of sets of brightness test data.
Firstly, aiming at the acquired multiple groups of brightness test data, abnormal data can be removed from the brightness test data, wherein the abnormal data are data which obviously exceed the brightness test expectation; then, the average value of the multiple groups of brightness test data after abnormal data are removed can be calculated.
If the average value exceeds a preset range, the brightness of the fingerprint image of the terminal device 11 can be adjusted. The preset range may be determined by a tester, and is not particularly limited in this exemplary embodiment. In addition, the degree to which the average value exceeds the preset range may be determined, and the brightness of the fingerprint image of the terminal device 11 may be adjusted according to the degree of the exceeding.
The brightness processing system of an on-screen fingerprint image according to the exemplary embodiment of the present disclosure will be described below taking a process in which a user inputs a command at the control device 12 to realize detection of the brightness of the fingerprint image of the terminal device 11 as an example. In this case, the terminal device 11 may be an android phone, the control device 12 may be a PC terminal, and the luminance detecting device 13 may be an illuminometer.
Firstly, a root authority version can be installed on an android mobile phone, USB debugging is opened, the android mobile phone is connected to a PC end, and ADB connection is ensured; then, a tester can touch and press the fingerprint identification area with a finger to lighten the fingerprint light spot, and simultaneously input an adb shell stop command in a command window of the PC end to enable the mobile phone screen to maintain the state that the fingerprint light spot is lightened; then, obtaining fingerprint facula brightness data through an illuminometer; then, an adb shell start command is input in a command window of the PC end, so that the mobile phone resumes operation. Therefore, the above process is repeated to obtain a plurality of groups of brightness data, and the brightness data is analyzed to determine whether to adjust the brightness of the fingerprint light spots.
According to the brightness processing system for the on-screen fingerprint image, which is disclosed by the exemplary embodiment of the invention, on one hand, the fingerprint image of the control terminal equipment is kept in a bright state to carry out brightness detection, so that the problem that an accurate and stable brightness detection result cannot be obtained due to short bright time of the fingerprint image in some technologies is avoided; on the other hand, by adopting the exemplary scheme of the disclosure, an accurate and stable fingerprint brightness detection result can be obtained, brightness can be adjusted by utilizing the result, and fingerprint identification effect can be improved; in still another aspect, the exemplary scheme of the present disclosure does not need to specially form a new test version, and can achieve the purpose of accurately detecting the brightness of the fingerprint under the condition of saving manpower and time.

Referring to fig. 3, the brightness processing method of the under-screen fingerprint image of the exemplary embodiment of the present disclosure may include step S32 and step S34.
In step S32, the terminal device may respond to the brightness test triggering operation, and control the fingerprint image to be lit up for a preset period of time; in step S34, if the terminal device receives the state maintaining instruction within a preset period of time, the terminal device controls the fingerprint image to maintain the lit state so as to detect the brightness of the fingerprint image by means of a brightness detecting device.
In addition, the terminal device can also respond to a state recovery instruction to recover the running state. Specifically, the state restoration instruction and the state maintenance instruction may be generated and issued by a control device.
The specific process is already described in the description of the brightness processing system of the under-screen fingerprint image, and will not be repeated here.
