Detailed ways

The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Before discussing the exemplary embodiments in greater detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart depicts the steps as a sequential process, many of the steps may be performed in parallel, concurrently, or concurrently. Furthermore, the order of the steps can be rearranged. The process may be terminated when its operation is complete, but may also have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

At present, the size of the display screen of the mobile terminal is getting larger and larger, and the user spends a lot of time using the mobile terminal every day, so the power consumption of the mobile terminal has become the most concerned problem for the user. Most of the fingerprint sensors configured in the mobile terminal are touch capacitive fingerprint sensors. Generally, when the user unlocks the mobile terminal in a black screen state (the system of the mobile terminal is in a dormant state), the user usually needs to touch the fingerprint sensor with a finger. At this time, the skin on the finger and the fingerprint sensor will form a capacitance, and the fingerprint sensor can detect the capacitance value to determine that the finger is touching the fingerprint sensor, the mobile terminal enters the bright screen state, and the fingerprint sensor obtains the fingerprint image. If the preset fingerprint template images stored in the terminal match, the mobile terminal is unlocked. However, when the user does not want to wake up the mobile terminal, the mobile terminal may also enter a bright screen state due to a body part such as the palm or other objects that can form capacitance with the fingerprint sensor touching the fingerprint sensor. For example, when the user holds the mobile terminal by hand, or when the mobile terminal is placed in a pocket of relatively thin cloth and contacts the user's skin or conductive objects, it is easy to trigger falsely and cause the display screen to be lit. After the display screen is lit, unnecessary power consumption of the mobile terminal will be increased, and the standby time will be shortened, thereby affecting the use of the user. The embodiments of the present invention can effectively avoid the occurrence of the above situation.

1 is a schematic flowchart of a control method for wake-up by fingerprint provided by an embodiment of the present invention. The method can be executed by a control device for wake-up by fingerprint, wherein the device can be implemented by software and/or hardware, and can generally be integrated in a mobile terminal. As shown in Figure 1, the method includes:

Step 101, it is detected that the mobile terminal is in a black screen state.

Exemplarily, the mobile terminal in this embodiment of the present invention may include mobile devices such as mobile phones, tablet computers, and media players, which are provided with a display screen and a touch-type fingerprint sensor.

Optionally, when the mobile terminal is in a black screen state, the system of the mobile terminal is in a dormant state. When the mobile terminal is in a black screen state, it means that the user does not use the mobile terminal or does not need to perform operations on the touch screen (for example, when listening to music). The mobile terminal can be woken up by touching the fingerprint sensor, and the fingerprint wake-up function can be enabled by default.

Step 102: Acquire the detection result of the proximity sensor of the mobile terminal.

Optionally, the proximity sensor of the mobile terminal may include an infrared proximity sensor, an ultrasonic sensor, etc. The embodiment of the present invention does not limit the specific type, quantity and position of the proximity sensor, for example, it may be an infrared proximity sensor located around the front camera. Taking the infrared proximity sensor as an example, the infrared proximity sensor emits infrared rays, and then judges the distance between the object and the sensor by measuring the infrared intensity reflected back by the object. the smaller the distance. The infrared proximity sensor will convert the measured infrared intensity into a measurement value that is proportional to it, which can be called the proximity value. the smaller the distance. In order for the infrared proximity sensor to detect the approaching or moving away of an object, the approach threshold value and the distance threshold value are generally set in advance. When the proximity value is greater than the proximity threshold value, the detection result can be determined to be in the proximity state; when the proximity value is less than the remote threshold value, the detection result can be determined to be in the remote state; when the proximity value is between the proximity threshold value and the remote threshold value , the current detection result is the same as the last detection result. For example, if the last detection result is a close state, the current detection result is a close state.

Step 103 , when the acquired detection result is the proximity state, turn off the fingerprint wake-up function, so as to keep the mobile terminal in a black screen state when it is detected that the fingerprint sensor is touched.

Wherein, the fingerprint sensor is a touch fingerprint sensor.

When the user wakes up and unlocks the mobile terminal by touching the fingerprint sensor, the proximity sensor is generally not blocked, so the proximity sensor should be kept away. If the detection result obtained in this step is a proximity state, it means that the user does not currently have the will to wake up and unlock the mobile terminal by touching the fingerprint sensor. For example, the mobile terminal is buckled on the desktop, or the mobile terminal is under the user's clothes. In the pocket, or the mobile terminal is in the user's luggage, the user will not actively touch the fingerprint sensor in these cases. Therefore, when the acquired detection result is the proximity state, the fingerprint wake-up function is turned off, so as to prevent the mobile terminal from being mistakenly switched to the bright screen state when it is detected that the fingerprint sensor is touched (in this case, it is a false touch), thereby causing the screen function to fail. consumption increases. It should be noted that the touch here is not limited to finger touch. When other parts of the user's body or other conductive objects touch the fingerprint sensor, it may be considered that the fingerprint sensor is touched.

In this embodiment of the present invention, disabling the fingerprint wake-up function may include controlling the fingerprint sensor to stop working (for example, stop supplying power to the fingerprint sensor, or continue supplying power to the fingerprint sensor but the fingerprint sensor does not detect changes in capacitance values); it may also include controlling the fingerprint sensor to detect When it is touched, the triggering of fingerprint wake-up interrupt is stopped, and further, operations related to fingerprint image matching may not be performed.

The fingerprint wake-up control method provided by the embodiment of the present invention detects that the mobile terminal is in a black screen state, obtains the detection result of the proximity sensor of the mobile terminal, and when the detection result is in the proximity state, disables the fingerprint wake-up function, so that when a touch-type sensor is detected When the fingerprint sensor is touched, the mobile terminal is kept in a black screen state, wherein the fingerprint sensor is a touch fingerprint sensor. By adopting the above technical solution, it can be avoided that the touch fingerprint sensor is accidentally touched and the mobile terminal is awakened by mistake.

In one embodiment, the above technical solution can be optimized. Specifically, when the acquired detection result is in the proximity state, turning off the fingerprint wake-up function includes: when the acquired detection result is in the proximity state, acquiring the touch area on the touch screen; when the touch area exceeds a preset area threshold, turning off the fingerprint wake-up function Function. The optimization here can improve the accuracy of determining whether the user has a fingerprint wake-up requirement.

When the detection result of the proximity sensor is the proximity state, it means that the proximity sensor of the mobile terminal is blocked. However, because the size of the proximity sensor is generally small, it may be accidentally blocked (for example, the proximity sensor of the mobile terminal placed on the desktop is not blocked. Be careful to be blocked by tissue or document objects, but the screen is not blocked), at this time, the user may have a need for fingerprint wake-up. If the fingerprint wake-up function is turned off, the user's active fingerprint wake-up operation may not be responded to. In the embodiment of the present invention, the condition for determining the touch area on the touch screen is further increased. When a user performs a fingerprint wake-up operation, they generally do not touch the touch screen, so when there is a large area of touch on the touch screen, it means that the user does not currently have the will to wake up the fingerprint. The reason for this may be that the user holds the mobile terminal while holding it. In addition to the proximity sensor and part of the screen, it may be that the user's skin touches the touch screen through the cloth when the mobile terminal is placed in the pocket, or the mobile terminal is placed in the pocket and the user's hand In the pocket of your clothes, you can turn off the fingerprint wake-up function at this time.

Exemplarily, the reference capacitance data on the touch screen surface can be collected when the mobile terminal is powered on or when the screen reference value calibration needs to be performed, generally tx*ty data, where tx and rx are the number of matrix channels in the horizontal and vertical directions of the touch screen, respectively. . When you need to detect the touch area, you can read the current tx*ty matrix capacitance data, and make a difference with the reference capacitance data collected before, and make the difference greater than the preset touch threshold (such as 60, which corresponds to the actual capacitance value). The position of the analog-to-digital conversion value, also known as AD value or ADC value) is determined as the touched position, and the touched position is counted to calculate the touch area. When the touch screen is not touched, the touch area is generally 0.

In this embodiment of the present invention, the preset area threshold can be set freely, for example, it can be a preset ratio value (eg, 30%) of the area of the touch screen.

Further, acquiring the touch area on the touch screen may include acquiring the touch area within a preset area on the touch screen. The preset area includes an area close to the fingerprint sensor relative to other areas. When an area other than the preset area is touched, it means that the touched object is far away from the fingerprint sensor, and it is difficult to cause a false touch to the fingerprint sensor. Therefore, in order to reduce the increased power consumption of the touch screen due to the detection of the touch area, the detection area can be reduced. When the touch area in the preset area exceeds the preset area threshold, the fingerprint wake-up function is turned off. The preset area threshold at this time may be a preset ratio value (eg 5%) of the preset area area, or may be 0.

In one embodiment, the above technical solution can be optimized. Specifically, when the acquired detection result is in the proximity state, turning off the fingerprint wake-up function includes: when the acquired detection result is in the proximity state, acquiring the step-counting result of the pedometer; when the number of steps in the step-counting result is When increasing, turn off the fingerprint wake-up function. The optimization here can improve the accuracy of determining whether the user has a fingerprint wake-up requirement.

As mentioned above, when the proximity sensor is in the proximity state, the user may still need the fingerprint to wake up, and the judgment of the pedometer result can be increased. If the number of steps in the pedometer result is increasing, it can indicate that the user is walking. It is rare that the proximity sensor is accidentally blocked, so it can be considered that the user has no need for fingerprint wake-up, and the fingerprint wake-up function is turned off.

Exemplarily, the pedometer in this embodiment of the present invention may be implemented by an acceleration sensor, which is also called an accelerometer or an accelerometer, and can be used to detect the magnitude and direction of the acceleration of the mobile terminal. When the user moves with the mobile terminal, the acceleration sensor may If the change value of acceleration is detected, if the value meets certain preset conditions (for example, the value exceeds the set change value, and the exceeding time is greater than the set time value), then it is regarded as a valid step, and then the user's speed is calculated. number of steps.

Preferably, in order to further improve the accuracy of determining whether the user has a fingerprint wake-up requirement, the above optimizations may be combined. Specifically, when the acquired detection result is in the proximity state, turning off the fingerprint wake-up function includes: when the acquired detection result is in the proximity state, acquiring the touch area on the touch screen; when the touch area exceeds a preset area threshold, acquiring The step counting result of the pedometer; when the number of steps in the step counting result is increasing, turn off the fingerprint wake-up function. Or include: when the acquired detection result is a close state, acquiring the step count result of the pedometer; when the number of steps in the step count result is increasing, acquiring the touch area on the touch screen; when the touch area exceeds a predetermined When the area threshold is set, the fingerprint wake-up function is turned off.

In one embodiment, acquiring the detection result of the proximity sensor in the mobile terminal may include: detecting a fingerprint unlocking failure event, and acquiring the detection result of the proximity sensor in the mobile terminal. The benefit of this optimization is that it reduces the power consumption of the proximity sensor to detect the proximity state in real time. When the fingerprint unlocking failure event is detected, it indicates that there may be a false trigger of the fingerprint sensor, and the proximity sensor is turned on and the detection result of the proximity sensor is obtained, so as to determine whether the fingerprint wake-up function needs to be turned off according to the above technical solution. Preferably, when the fingerprint unlocking failure event is detected, the mobile terminal is kept in a black screen state. Further, it is detected that the mobile terminal is in a black screen state, and when it is detected that the fingerprint sensor is touched, the mobile terminal is kept in a black screen state, the current fingerprint image is collected, and the current fingerprint image is matched with the preset fingerprint template. A fingerprint unlocking failure event is detected, the mobile terminal is kept in a black screen state, and the detection result of the proximity sensor of the mobile terminal is obtained.

Further, after the fingerprint wake-up function is turned off, it can be confirmed that the previous unlocking failure was caused by a false touch, and the statistical result of the number of fingerprint unlocking failures is reset to zero. When the user performs fingerprint unlocking on the mobile terminal, the number of unlocking failures will accumulate. After the preset number of times is exceeded, the fingerprint unlocking function will be suspended to prevent others from trying to unlock multiple times. When it is confirmed that the previous unlocking failure was caused by a false touch, the statistical result is cleared to avoid impact on the user's subsequent operations. For example, shortly after the fingerprint wake-up function is turned off, the user takes the initiative to turn on the fingerprint wake-up function (or the fingerprint wake-up function is automatically turned on), and performs fingerprint unlocking. The number of times is reduced (the user may need to try to unlock multiple times when there is oil or sweat on the user's finger), which affects the user's use.

In one embodiment, after turning off the fingerprint wake-up function, the method further includes: when it is determined that the detection result of the proximity sensor is changed to a remote state, turning on the fingerprint wake-up function. When the detection result of the proximity sensor switches from the close state to the far state, it means that the user is likely to take the mobile terminal out of his pocket or from the desktop, then the user will have the need for fingerprint wake-up, and the fingerprint wake-up function will be automatically enabled. There is no need for the user to manually open it to ensure the normal use of the user.
