The detailed descriptions will be given below.

In this embodiment, description will be given from the perspective of a control device for fingerprint unlocking, which can be integrated into a terminal such as a mobile phone, a tablet computer, and a PDA (Personal Digital Assistant).

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a control method for fingerprint unlocking provided by an embodiment of the present invention. The method includes:

In step S101, a screen state of the terminal is acquired in a state in which the terminal turns on the fingerprint unlocking module.

In the embodiment of the present invention, the fingerprint unlocking module mainly includes a fingerprint sensing device and a fingerprint information processing chip, wherein the fingerprint sensing device is used for receiving an instruction touch operation input by a user, and the fingerprint information processing chip is used for verifying the validity of the touch operation.

For example, firstly, the terminal enables the fingerprint unlocking function, that is, the fingerprint unlocking module is in the enabled state, and then the screen state of the terminal is obtained; in this embodiment, the screen state may specifically include the state of the screen-off operation, the black-screen state, and the state of the screen-bright operation. and the status of the unlocking operation, etc.

Among them, the screen-on operation refers to the operation that triggers the terminal screen from bright screen to black screen. After the screen-off operation, the terminal will enter the black screen state; the screen-on operation refers to the operation that triggers the terminal screen from black to bright screen, and the unlock operation refers to The terminal screen is unlocked.

In step S102, based on the screen state, it is determined whether the terminal needs to enter a preset power saving mode, where the preset power saving mode instructs the terminal to enable the proximity sensor provided on the terminal when the screen is in a black state.

In step S103, when it is determined that the terminal needs to enter the preset power saving mode and the current screen state is a black screen state, the proximity sensor provided on the terminal is enabled and monitored.

For example, according to the obtained screen state, the terminal determines whether to enable the proximity sensor set on the terminal in the black screen state, that is, whether to allow the proximity sensor to perform power saving protection in the black screen state; when it is allowed and the current screen state enters the black screen state Only when the proximity sensor set on the terminal can be enabled, that is, the preset power saving mode is entered.

In this embodiment of the present invention, the proximity sensor may also be called a distance sensor, and mainly determines whether the terminal is covered or blocked by detecting the distance value. The proximity sensor may specifically be an infrared sensor, an ultrasonic sensor, or a magnetic induction sensor, etc. Here There is no specific limitation.

It can be understood that the prerequisite for controlling the activation or deactivation of the proximity sensor is that the terminal has enabled corresponding functions, such as enabling fingerprint unlocking, and allowing the proximity sensor to perform power saving protection in a black screen state. In this embodiment of the present invention, the proximity sensor can be successfully enabled only when the screen is in a black state.

In the embodiment of the present invention, there are many implementations for the terminal to "determine whether the terminal needs to enter the preset power saving mode based on the screen state", and in some implementations, it may include:

(11) When the screen state of the terminal is the screen-off operation, obtain the total amount of current generated by the fingerprint unlocking module.

(12) If the total amount of current reaches the preset current threshold, it is determined that the terminal needs to enter the preset power saving mode.

For example, when the screen state of the terminal is the screen-off operation, the total amount of current generated by the fingerprint unlocking module is obtained. If the total amount of current reaches the preset current threshold, it is determined that the terminal needs to enter the preset power saving mode, that is, the close proximity mode is allowed to be enabled. Sensor and power-saving protection in black screen state; after the screen-off operation, the terminal enters the black screen state and enables proximity sensor and monitoring.

Among them, the total amount of current accumulated by the terminal is related to the verification result of the fingerprint unlocking module. For example, when the terminal is placed in the pocket under the condition of black screen, it will easily trigger false touches, which will lead to the failure of the fingerprint unlocking module if the number of verification failures reaches a certain number, causing the black screen function. Therefore, if it is determined that the received touch operation verification fails, such as the current image is not a fingerprint, etc., the current amount of current generated by the fingerprint unlocking module is calculated, and the total current generated by the fingerprint unlocking module is updated.

For another example, in some embodiments, "determining whether the terminal needs to enter the preset power saving mode based on the screen state" of the terminal may include:

When the screen state of the terminal is a black screen state, if it is detected that a touch operation is received in the fingerprint unlocking area, it is determined that the terminal needs to enter a preset power saving mode.

Based on this, in some embodiments, after the terminal "enables and monitors the proximity sensor provided on the terminal", it may further include: if it is determined that the touch operation verification fails, controlling the terminal to exit the preset power saving mode, and disable the Proximity sensor.

That is to say, when the screen is off, if the total accumulated current of the terminal has reached the preset current threshold, the proximity sensor monitoring will be enabled, otherwise it will not be enabled; when the screen is currently in a black state, if the user touches the fingerprint area, it will also be enabled Proximity sensor monitoring, when enabled, when it is determined that the fingerprint verification is unsuccessful, the terminal will trigger the process of performing the screen-off operation, and the proximity sensor monitoring will be disabled immediately.

In some embodiments, after the terminal "enables and monitors the proximity sensor provided on the terminal", it may further include:

When it is detected that the screen state of the terminal is performing a screen-on operation or performing an unlocking operation, the terminal is controlled to exit the preset power saving mode, and the proximity sensor is disabled.

That is, performing a screen brightening operation or performing an unlocking operation in a black screen state will trigger the screen brightening operation. If the screen brightening occurs, the proximity sensor monitoring is immediately disabled regardless of the previous state.

In step S104, the use state of the fingerprint unlocking module is controlled according to the monitoring result of the proximity sensor.

In this embodiment of the present invention, there are many implementations in which the terminal "controls the use state of the fingerprint unlocking module according to the monitoring result of the proximity sensor", for example, it may include:

(21) If the distance value monitored by the proximity sensor meets the preset threshold, obtain the total amount of current generated by the fingerprint unlocking module, and determine whether the total amount of current reaches the preset current threshold.

(22) If the total amount of current does not reach the preset current threshold, control the fingerprint unlocking module to be in an enabled state.

(23) If the total amount of current reaches the preset current threshold, the fingerprint unlocking module is controlled to be in a deactivated state.

It can be understood that, on the premise that the proximity sensor has been enabled for monitoring, first determine whether the distance value monitored by the proximity sensor meets the preset threshold, that is, determine whether the terminal is covered or blocked.

If the distance value monitored by the proximity sensor meets the preset threshold, it means that the proximity sensor is covered. It is further determined whether the total current generated by the current fingerprint unlocking module reaches the preset current threshold. If not, the fingerprint unlocking module will not be disabled. , the fingerprint unlocking module is controlled to be in the enabled state; if it is reached, the fingerprint unlocking module is disabled, and the fingerprint unlocking module is controlled to be disabled.

Further, after the terminal "controls the fingerprint unlocking module to be in a disabled state", the fingerprint unlocking module can also be restarted, for example:

When the distance value monitored by the proximity sensor does not meet the preset threshold, or when it is detected that the screen state of the terminal is performing a screen-on operation, the fingerprint unlocking module is re-enabled.

In some embodiments, when the distance value monitored by the proximity sensor meets the preset threshold, it may also include:

If it is detected that the fingerprint unlocking area receives a touch operation verification failure, the current amount of current generated by the fingerprint unlocking module is calculated, and the total amount of current generated by the fingerprint unlocking module is updated.

In addition, in some embodiments, after the terminal "enables and monitors the proximity sensor provided on the terminal", it may further include: clearing the total amount of current generated by the fingerprint unlocking module according to a preset time interval.

For example, under the premise that the proximity sensor has been enabled for monitoring, the fingerprint unlocking module detects that the current touch operation verification fails. If the image captured by the touch is not a fingerprint or the fingerprint is incorrect, the current is accumulated to obtain the total current, the current The total amount is used to determine whether the set current threshold is reached; and it is set to clear the current total amount once at a preset time interval.

The terms "first", "second" and "third" in the present invention are used to distinguish different objects, rather than to describe a specific order. Furthermore, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

As can be seen from the above, in the control method for fingerprint unlocking provided by this embodiment, when the terminal turns on the fingerprint unlocking module, based on the screen state of the terminal, it is determined whether the terminal needs to enter the preset power saving mode, that is, whether it needs to be enabled in the black screen state. The proximity sensor installed on the terminal, if it is, enable the proximity sensor and monitor it in the black screen state, and control the use state of the fingerprint unlocking module according to the monitoring result of the proximity sensor; that is to say, the present invention adds the proximity sensor in the black screen state. The sensor is used to judge, so as to avoid unnecessary power consumption caused by accidental touch under the black screen, realize the power saving protection of the terminal, and improve the battery life effect.

According to the methods described in the above embodiments, the following examples will be used for further detailed description.

Since the terminal (such as a mobile phone) is in a black screen state, if the anti-mistouch processing is not performed, the fingerprint unlocking module will always be enabled, which will easily lead to high power consumption of the terminal, and the power-saving protection of fingerprints under the black screen is not well realized. Based on this, in the embodiment of the present invention, a proximity sensor installed on the mobile phone is introduced for monitoring, and the use state of the fingerprint unlocking module is controlled according to the monitoring result, so as to realize the power saving protection of the fingerprint under the black screen.

Please refer to FIG. 2a. FIG. 2a is another schematic flowchart of a control method for fingerprint unlocking provided by an embodiment of the present invention. The method can include:

In step S201, the terminal enables fingerprint unlocking, and allows the proximity sensor to perform power saving protection in a black screen state.

In step S202, the screen state of the terminal is acquired.

In step S203, based on the screen state, it is determined whether the terminal enables the proximity sensor provided on the terminal when the terminal is in a black screen state.

In this embodiment, the screen state may specifically include a state of performing a screen-off operation, a black-screen state, a state of performing a screen-bright operation, a state of performing an unlocking operation, and the like.

Among them, the screen-on operation refers to the operation that triggers the terminal screen from bright screen to black screen. After the screen-off operation, the terminal will enter the black screen state; the screen-on operation refers to the operation that triggers the terminal screen from black to bright screen, and the unlock operation refers to The terminal screen is unlocked.

It can be understood that the prerequisite for controlling the activation or deactivation of the proximity sensor is that the terminal has enabled fingerprint unlocking, and the proximity sensor is allowed to perform power saving protection in a black screen state. In this embodiment of the present invention, the proximity sensor can be successfully enabled only when the screen is in a black state.

Please refer to Table 1, which is a schematic diagram of the activation or deactivation of the proximity sensor.

Table 1

That is, in the screen states of different terminals, the proximity sensor is controlled to be activated or deactivated by judging the preset parameters. In this embodiment, two parameters, the fingerprint mode and the total amount of current generated by the fingerprint unlocking module, are introduced, combined with the screen state, to determine whether the terminal enables the proximity sensor in the black screen state.

Among them, in Table 1, "0-touch" in the fingerprint mode refers to the state in which only touch operations are received but no verification is performed, which may mainly include fingerprint input or password input errors exceeding a certain number (such as 5 times), or user identification. The status of the card sim card lock, etc., "1-auth" refers to the status of verifying the touch operation of fingerprint unlocking, and "X" means no judgment.

"0-Unreached" in the current threshold means that the total accumulated current generated by the fingerprint unlocking module does not reach the preset current threshold, and "1-reached" means that the accumulated current generated by the fingerprint unlocking module has reached the preset current threshold. , "X" means no judgment.

Among them, the total accumulated current is related to the verification result of the fingerprint unlocking module. For example, in the case of a black screen, placing the terminal in the pocket will easily trigger false touches, which will lead to the failure of the fingerprint unlocking module if the number of verification failures reaches a certain number, resulting in black screen power consumption. high; therefore, if it is determined that the received touch operation verification fails, such as the current image is not a fingerprint, etc., the current amount of current generated by the fingerprint unlocking module is accumulated.

In one embodiment, when the screen status of the terminal is the screen-off operation:

1-1. If the fingerprint mode is "0", the proximity sensor is enabled.

1-2. If the fingerprint mode is "1" and the current threshold is "0", the proximity sensor is disabled.

1-3. If the fingerprint mode is "1" and the current threshold is "1", the proximity sensor is enabled.

In another implementation manner, after the screen-off operation is performed, the terminal will enter a black-screen state:

2-1. If the fingerprint mode is "0", the current state of the proximity sensor will be maintained and no operation will be performed.

2-2. If the fingerprint mode is "1", the proximity sensor will be enabled when a touch operation is received.

However, when it is determined that the verification of the touch operation fails, the triggering path 2 of the screen-on-screen process is executed, and the proximity sensor is disabled.

That is to say, when the screen is off, if the total accumulated current of the terminal has reached the preset current threshold, the proximity sensor monitoring will be enabled, otherwise it will not be enabled; when the screen is currently in a black state, if the user touches the fingerprint area, it will also be enabled Proximity sensor monitoring, when enabled, when it is determined that the fingerprint verification is unsuccessful, the terminal will trigger the process of performing the screen-off operation, and the proximity sensor monitoring will be disabled immediately.

It can be understood that when the screen state of the terminal is to perform a screen-on operation or to perform an unlock operation, the proximity sensor is disabled, that is, if the screen-on occurs, the proximity sensor monitoring is immediately disabled regardless of the previous state.

In step S204, when it is determined that the proximity sensor needs to be activated and the current screen state is a black screen state, the proximity sensor is activated and monitored.

In step S205, according to the monitoring result of the proximity sensor, the fingerprint unlocking module is controlled to be disabled or enabled.

The following is a simple analysis of the control strategy for controlling the deactivation or activation of the fingerprint unlocking module:

First of all, because the current fingerprint processing in the black screen state is no different from the bright screen situation, the verification is successful and the unlock is performed, and the verification fails, the count is counted. The failure count reaches a certain number of times (such as 5 times) and fails, causing high black screen power consumption. Therefore, the embodiment of the present invention adds a strategy of proximity sensor monitoring (Strategy 1), monitoring is performed when the screen is black, and fingerprints are disabled if the proximity sensor is covered. Unlock the module, then re-enable the fingerprint module when away from the proximity sensor or when the screen is on.

However, because the proximity sensor is covered and cannot be unlocked, the strategy for monitoring the proximity sensor is further optimized (Strategy 2): monitor when the screen is black. If the proximity sensor is covered, the fingerprint unlocking module will not be disabled, and the fingerprint verification will be successful. Fingerprint verification failure will not count and will not turn on the screen.

Further, considering the above two strategies, the current threshold is introduced for compatibility: monitoring when the screen is black, if the total current does not reach the current threshold when the proximity sensor is covered, the fingerprint unlocking module will not be disabled, and the fingerprint verification is successful. The screen will be unlocked and the screen will not be turned on if the fingerprint verification fails. If the total current has reached the current threshold when the proximity sensor is covered, the fingerprint unlocking module will be disabled. Please refer to Figure 2b. If the proximity sensor is covered, the current total The amount has reached the current threshold. When the object moves from position A to position B, it can be considered that the object is currently close to the proximity sensor. When the distance reaches the preset threshold, that is, the proximity sensor is covered, the fingerprint unlocking module is controlled to be disabled.

After that, the fingerprint unlocking module will be re-enabled when it is far away from the proximity sensor or the screen is bright. Please refer to Figure 2c. When the object moves from position B to position A, it can be considered that the current object is far away from the proximity sensor, and the distance between the two does not reach the preset threshold. Then control to re-enable the fingerprint unlocking module.

You can refer to Table 2 together, which shows the specific performance of the product when the proximity sensor power saving protection is enabled in a black screen state.

Table 2

Among them, "0-fail" in fingerprint identification means fingerprint verification fails, "1-success" means fingerprint verification succeeds, and "X" means no judgment.

It can be understood that under the premise that the proximity sensor has been enabled for monitoring, the fingerprint unlocking module detects that the fingerprint verification fails. If the image captured by the touch is not a fingerprint or the fingerprint is incorrect, the current is accumulated to obtain the total current, which is the The total current is used to determine whether the set current threshold is reached; and it is set to reset the total current once at a preset time interval, such as once every 24 hours, and so on.

The following is a self-checking description of the proximity sensor function: For example, set the default to allow the proximity sensor to perform power saving protection under black screen, and set the current threshold to 50mAH, and these two values can be adjusted according to the needs of the strategy, such as can be updated through the memory (romupdate) function to adjust.

As can be seen from the above, in the control method for fingerprint unlocking provided by this embodiment, when the terminal turns on the fingerprint unlocking module, based on the screen state of the terminal, it is determined whether the terminal needs to enter the preset power saving mode, that is, whether it needs to be enabled in the black screen state. The proximity sensor installed on the terminal, if it is, enable the proximity sensor and monitor it in the black screen state, and control the use state of the fingerprint unlocking module according to the monitoring result of the proximity sensor; that is to say, the present invention adds the proximity sensor in the black screen state. The sensor is used to judge, so as to avoid unnecessary power consumption caused by accidental touch under the black screen, realize the power saving protection of the terminal, and improve the battery life effect. In addition, the proximity sensor can also be activated or deactivated according to different situations to ensure that the sensor will not cause excessive power consumption; in the black screen state, the fingerprint module can be activated or deactivated according to the monitoring results of the proximity sensor, taking into account power consumption and experience; Moreover, the power saving protection strategy can be dynamically adjusted through the server according to the actual situation.

In order to facilitate better implementation of the fingerprint unlocking control method provided by the embodiment of the present invention, an embodiment of the present invention further provides an apparatus and computer equipment based on the above fingerprint unlocking control method. The meanings of the nouns are the same as those in the above-mentioned method for controlling fingerprint unlocking. For specific implementation details, please refer to the description in the method embodiment.

Please refer to FIG. 3 , which is a schematic structural diagram of a fingerprint unlocking control device according to an embodiment of the present invention. The fingerprint unlocking control device 300 includes an acquisition module 301 , a determination module 302 , a monitoring module 303 and a control module 304 .

The obtaining module 301 is used for obtaining the screen state of the terminal when the terminal turns on the fingerprint unlocking module.

In the embodiment of the present invention, the fingerprint unlocking module mainly includes a fingerprint sensing device and a fingerprint information processing chip, wherein the fingerprint sensing device is used for receiving an instruction touch operation input by a user, and the fingerprint information processing chip is used for verifying the validity of the touch operation.

For example, firstly, the terminal enables the fingerprint unlocking function, that is, the fingerprint unlocking module is in the enabled state, and then the screen state of the terminal is obtained; in this embodiment, the screen state may specifically include the state of the screen-off operation, the black-screen state, and the state of the screen-bright operation. and the status of the unlocking operation, etc.

Among them, the screen-on operation refers to the operation that triggers the terminal screen from bright screen to black screen. After the screen-off operation, the terminal will enter the black screen state; the screen-on operation refers to the operation that triggers the terminal screen from black to bright screen, and the unlock operation refers to The terminal screen is unlocked.

The determining module 302 is configured to determine, based on the screen state, whether the terminal needs to enter a preset power saving mode, where the preset power saving mode instructs the terminal to enable a proximity sensor provided on the terminal when the terminal is in a black screen state.

The monitoring module 303 is configured to enable and monitor the proximity sensor provided on the terminal when it is determined that the terminal needs to enter the preset power saving mode and the current screen state is a black screen state. The control module 304 is configured to control the usage state of the fingerprint unlocking module according to the monitoring result of the proximity sensor.

For example, according to the obtained screen state, the terminal determines whether to enable the proximity sensor set on the terminal in the black screen state, that is, whether to allow the proximity sensor to perform power saving protection in the black screen state; when it is allowed and the current screen state enters the black screen state Only when the proximity sensor set on the terminal can be enabled, that is, the preset power saving mode is entered.

In this embodiment of the present invention, the proximity sensor mainly determines whether the terminal is covered or blocked by detecting the distance value. The proximity sensor may specifically be an infrared sensor, an ultrasonic sensor, or a magnetic induction sensor, which is not specifically limited here.

It can be understood that the prerequisite for controlling the activation or deactivation of the proximity sensor is that the terminal has enabled corresponding functions, such as enabling fingerprint unlocking, and allowing the proximity sensor to perform power saving protection in a black screen state. In this embodiment of the present invention, the proximity sensor can be successfully enabled only when the screen is in a black state.

Please refer to FIG. 4 together. FIG. 4 is a schematic structural diagram of a fingerprint unlocking control device 400 according to an embodiment of the present invention.

In this embodiment of the present invention, the determining module 302 in the fingerprint unlocking control device 400 determines whether the terminal needs to enter the preset power saving mode based on the screen state. There are many implementations. In some implementations, it may include:

The first acquisition sub-module 3021 is used to acquire the total amount of current generated by the fingerprint unlocking module when the screen state of the terminal is the screen-off operation.

The first determination sub-module 3022 is configured to determine that the terminal needs to enter a preset power saving mode if the total amount of current reaches a preset current threshold.

For example, when the screen state of the terminal is the screen-off operation, the total amount of current generated by the fingerprint unlocking module is obtained. If the total amount of current reaches the preset current threshold, it is determined that the terminal needs to enter the preset power saving mode, that is, the close proximity mode is allowed to be enabled. Sensor and power-saving protection in black screen state; after the screen-off operation, the terminal enters the black screen state and enables proximity sensor and monitoring.

Among them, the total amount of current accumulated by the terminal is related to the verification result of the fingerprint unlocking module. For example, when the terminal is placed in the pocket under the condition of black screen, it will easily trigger false touches, which will lead to the failure of the fingerprint unlocking module if the number of verification failures reaches a certain number, causing the black screen function. Therefore, if it is determined that the received touch operation verification fails, such as the current image is not a fingerprint, etc., the current amount of current generated by the fingerprint unlocking module is calculated, and the total current generated by the fingerprint unlocking module is updated.

For another example, in some embodiments, as shown in FIG. 4 , the determining module 302 may further include:

The second determination sub-module 3023 is configured to determine that the terminal needs to enter a preset power saving mode if it is detected that the fingerprint unlocking area receives a touch operation when the screen state of the terminal is a black screen state.

Based on this, in some embodiments, the control device 400 for fingerprint unlocking may further include: a first disabling module 305, configured to control the terminal to exit the preset power saving mode if it is determined that the touch operation verification fails, and stop with the proximity sensor.

That is to say, when the screen is off, if the total accumulated current of the terminal has reached the preset current threshold, the proximity sensor monitoring will be enabled, otherwise it will not be enabled; when the screen is currently in a black state, if the user touches the fingerprint area, it will also be enabled Proximity sensor monitoring, when enabled, when it is determined that the fingerprint verification is unsuccessful, the terminal will trigger the process of performing the screen-off operation, and the proximity sensor monitoring will be disabled immediately.

As shown in FIG. 4 , in some embodiments, the control device 400 for fingerprint unlocking may further include:

The second deactivation module 306 is configured to control the terminal to exit the preset power saving mode and deactivate the proximity sensor when it is detected that the screen state of the terminal is performing a screen-on operation or performing an unlocking operation.

That is, performing a screen brightening operation or performing an unlocking operation in a black screen state will trigger the screen brightening operation. If the screen brightening occurs, the proximity sensor monitoring is immediately disabled regardless of the previous state.

In this embodiment of the present invention, the control module 304 in the fingerprint unlocking control device 400 controls the use state of the fingerprint unlocking module according to the monitoring result of the proximity sensor. There are many implementations. For example, as shown in FIG. :

The second acquisition sub-module 3041 is configured to acquire the total amount of current generated by the fingerprint unlocking module if the distance value monitored by the proximity sensor meets the preset threshold.

The judgment sub-module 3042 is used for judging whether the total amount of current reaches a preset current threshold.

The first control sub-module 3043 is configured to control the fingerprint unlocking module to be in an enabled state if the total amount of current does not reach the preset current threshold.

The second control sub-module 3044 is configured to control the fingerprint unlocking module to be in a disabled state if the total amount of current reaches a preset current threshold.

It can be understood that, on the premise that the proximity sensor has been enabled for monitoring, first determine whether the distance value monitored by the proximity sensor meets the preset threshold, that is, determine whether the terminal is covered or blocked; if the distance value monitored by the proximity sensor meets the The preset threshold means that the proximity sensor is covered, and it is further judged whether the total current generated by the current fingerprint unlocking module reaches the preset current threshold.
