Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The fingerprint identification method provided by the embodiment of the invention can be applied to terminal equipment, wherein the terminal equipment comprises a touch screen and a fingerprint identification module arranged under the touch screen, and the touch screen comprises a fingerprint identification area corresponding to the fingerprint identification module.
The fingerprint identification module specifically can show as: optical fingerprint identification module, ultrasonic fingerprint identification module, but not be limited to this, the present invention does not therefore limit the concrete expression form of fingerprint identification module.
The fingerprint identification area may be a partial area in the touch screen. For example, as shown in fig. 2, a touch screen of the terminal device is provided with a fingerprint identification area, and the fingerprint identification area may cover only a small portion of the touch screen. In the use process, a user can hardly accurately press the finger in the fingerprint identification area, so that the difficulty of the fingerprint identification process is improved.
In practical applications, the terminal Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), a Computer, or a notebook Computer, which can perform fingerprint identification, and the fingerprint identification area is disposed in a touch screen of the terminal Device.
It should be noted that the fingerprint identification method provided by the embodiment of the present invention may be applied to a screen-off scene of the terminal device, and may also be applied to a screen-on scene of the terminal device. For example: under the bright screen state of the mobile phone, if the payment verification is carried out in a fingerprint identification mode, the distance between the finger and the fingerprint identification area can be acquired, and the fingerprint identification area is displayed under the condition that the distance is reduced to a first preset distance, so that the user can press the fingerprint in the area. Or, in the screen-off state of the mobile phone, the fingerprint identification area may be displayed under the condition that the distance between the finger and the fingerprint identification area is reduced to a first preset distance, so that the user may press the fingerprint in the area to perform a screen unlocking operation.
Referring to fig. 1, fig. 1 is a flowchart of a fingerprint identification method according to an embodiment of the present invention. As shown in fig. 1, the fingerprint identification method according to the embodiment of the present invention may include the following steps:
and 101, acquiring a target distance between an operation body and the fingerprint identification area.
In practical applications, the target distance may be: the vertical distance between the operating body and the fingerprint identification area, or the linear distance between the operating body and the fingerprint identification area may be determined according to actual conditions, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the present invention, the operation body may be any operation part of a human body, for example: fingers, wrists, etc. Of course, it may also be a device or a component such as a capacitance pen, and is not limited in particular.
And 102, displaying the fingerprint identification area under the condition that the target distance is smaller than or equal to a first preset distance.
The first preset distance may be set according to a use habit of a user, for example: set to 3 centimeters (cm).
In particular implementations, the displaying the fingerprint identification area may appear to highlight the fingerprint identification area, for example: and visually enhancing and displaying the fingerprint identification area.
Further, the fingerprint identification area may be visually enhanced by:
changing the brightness of the fingerprint identification area; alternatively, the first and second electrodes may be,
displaying the animation; alternatively, the first and second electrodes may be,
the boundaries of the fingerprint identification area are displayed.
It should be noted that, in addition to the above-mentioned modes, the visual enhancement display of the fingerprint identification area may also be implemented by any other mode that enables a user to know the fingerprint identification area, and is not limited in particular herein.
Through the step, the terminal equipment can display the fingerprint identification area when the finger of the user is close to the screen. Like this, not only can make the user can be accurate input the fingerprint in this region, improve fingerprint identification's efficiency, furtherly, compares in prior art, can also avoid terminal equipment to show fingerprint identification region under the condition that need not carry out fingerprint identification operation to can reduce terminal equipment's power consumption, and then can reduce terminal equipment's energy consumption.
In the embodiment of the invention, the touch screen of the terminal equipment comprises a fingerprint identification area corresponding to the fingerprint identification module, and the target distance between an operation body and the fingerprint identification area is obtained; and displaying the fingerprint identification area under the condition that the target distance is less than or equal to a first preset distance. Therefore, the terminal of the embodiment of the invention displays the fingerprint identification area only when detecting that the operating body is close to the fingerprint identification area, so that the time for displaying the fingerprint identification area can be shortened compared with the prior art, and the energy consumption of the terminal equipment can be further reduced.
Referring to fig. 3, fig. 3 is a second flowchart of a fingerprint identification method according to an embodiment of the present invention. The main difference between this embodiment and the foregoing embodiment is that the displaying of the fingerprint identification area is further limited when the target distance is less than or equal to a first preset distance, specifically: displaying the fingerprint identification area under the condition that the target distance is smaller than or equal to the first preset distance and larger than a second preset distance, wherein the second preset distance is smaller than the first preset distance; in addition, after the fingerprint identification area is displayed, the fingerprint identification method is further limited, specifically: and under the condition that the target distance is reduced to be smaller than or equal to a second preset distance, controlling the fingerprint identification module to perform fingerprint identification on the operation body.
As shown in fig. 3, the fingerprint identification method according to the embodiment of the present invention may specifically include the following steps:
and 301, acquiring a target distance between an operation body and the fingerprint identification area.
It should be noted that this step is the same as step 101 in the foregoing method embodiment, and specific reference may be made to the related description of step 101, and details are not repeated here to avoid repetition.
And 303, controlling the fingerprint identification module to perform fingerprint identification on the operation body under the condition that the target distance is reduced to be smaller than or equal to a second preset distance.
In a specific implementation, the controlling the fingerprint identification module to perform fingerprint identification on the operation body may include: start fingerprint identification module. Further, the controlling the fingerprint identification module to perform fingerprint identification on the operation body may further include: control fingerprint identification module or screen are luminous, or control fingerprint identification module and send the ultrasonic wave. Further, the controlling the fingerprint identification module to perform fingerprint identification on the operation body may further include: fingerprint information is acquired. Like this, can avoid just beginning to open the fingerprint identification module and acquire fingerprint information and prolonged the time length of fingerprint identification process when the touch-control screen is touched to the operation body. Of course, control fingerprint identification module group to the concrete process that the operating body carries out fingerprint identification can change according to the principle of fingerprint identification module.
For example, when the fingerprint identification module is an optical fingerprint module and the target distance is less than or equal to a first preset distance and greater than a second preset distance, controlling the brightness of the fingerprint identification area to be adjusted to a first brightness value; when the target distance is reduced to be smaller than or equal to a second preset distance, the brightness of the target area in the fingerprint identification area is adjusted to be a second brightness value, wherein the second brightness value is larger than the first brightness value, so that the light of the second brightness value can illuminate the operation body, the optical fingerprint module can acquire a clearer fingerprint image, and when the operation body touches the touch screen, the acquired fingerprint image is matched with the prestored fingerprint information to determine whether the fingerprint identification passes the verification.
In a specific implementation, the brightness of the target region may be adjusted to the second brightness value at least in the following two ways: the first method is to adjust the display brightness of the touch screen in the target area; in the second mode, the optical fingerprint identification module arranged below the touch screen emits light, so that the brightness of the target area reaches the second brightness value.
Wherein the second luminance value can be understood as: the fingerprint identification module can gather the minimum threshold value of clear fingerprint image. That is to say, if the luminance of target area is less than the second luminance value, fingerprint identification module utilizes the fingerprint image of gathering to carry out fingerprint identification, and fingerprint identification's throughput is lower. The specific value of the second brightness value can be determined according to the requirements of the optical fingerprint identification module and the position of the target area.
Preferably, the target area is an orthographic projection area of the operating body in the fingerprint identification area. Like this, can be in the luminance adjustment of target area is the condition of second luminance value, makes the light irradiation of second luminance value to the operating body on to the fingerprint image that makes the discernment of optics fingerprint identification module is more clear, thereby has promoted the throughput rate of fingerprint identification method.
In this embodiment, when the target distance is less than or equal to the first preset distance and greater than the second preset distance, the brightness of the fingerprint identification area may be controlled to be adjusted to the first brightness value, and the user is reminded of the position of the fingerprint identification area by the first brightness value with a lower brightness value, so as to avoid excessive power consumption caused by excessively high brightness of the fingerprint identification area; in addition, when the target distance is reduced to be less than or equal to the second preset distance, the brightness of the control target area is adjusted to be the second brightness value, so that the fingerprint identification module acquires a clearer fingerprint image, and the passing rate and the accuracy rate of the fingerprint identification method are improved.
Further, after the target distance is detected to be smaller than or equal to a second preset distance, if the operating body leaves the fingerprint identification area, that is, the target distance is increased to be larger than the second preset distance, the brightness of the target area can be restored to the first brightness, or after the target distance is increased to be larger than the first preset distance, the fingerprint identification area is not displayed, that is, the fingerprint identification area is restored to a black screen in a screen-off state, and a conventional interface is displayed in a screen-on state. Therefore, when fingerprint identification is not needed, the fingerprint identification area is not displayed or the target area is not highlighted, so that the electric quantity of the terminal equipment is saved.
In practical application, the first preset distance and the second preset distance may be set according to a requirement of a user. In the following, an embodiment in which the operation body is represented by a finger and the terminal device is represented by a mobile phone will be described as an example.
For example, as shown in the application scene diagrams of the fingerprint identification method shown in fig. 4 to 7, in the present embodiment, the first preset distance is 3cm, and the second preset distance is 5 millimeters (mm). Fig. 4 shows that the distance between the finger and the fingerprint identification area is less than or equal to 3cm, that is, the target distance is less than or equal to a first preset distance, at this time, the terminal device is in the state shown in fig. 5, which is specifically represented as: and displaying the fingerprint identification area.
If the finger further approaches the fingerprint identification area, and the distance between the finger and the fingerprint identification area is less than or equal to 5mm as shown in fig. 6 is reached, that is, the target distance is less than or equal to the second preset distance, the terminal device is in the state as shown in fig. 7, which is specifically represented as: and adjusting the brightness of the control target area to be a second brightness value, and starting the fingerprint identification module.
The fingerprint identification method in this embodiment can reduce to being less than or equal to when 5mm at the distance between finger and the fingerprint identification region, adjust the luminance in target area to the second luminance value to open the fingerprint identification module, in order before finger touch-control fingerprint identification region, acquire fingerprint information, promote fingerprint identification's throughput and efficiency.
In this embodiment, the distance between the finger marked in fig. 4 and fig. 6 and the touch screen is the target distance, which represents the vertical distance between the finger and the fingerprint identification area in the touch screen.
In this embodiment, the target area is an orthographic projection area of the finger in the fingerprint identification area, and in specific application, the target area may also be the entire touch screen or the entire fingerprint identification area, and the like, which is not specifically limited herein.
In the embodiment of the present invention, the target distance may also be detected by using a two-stage proximity detection sensor, that is, two different distance detection devices are used to detect the target distance.
As an optional implementation manner, the terminal device further includes a first distance detection sensor and a second distance detection sensor, and the operating power consumption of the first distance detection sensor is lower than the operating power consumption of the second distance detection sensor;
the acquiring of the target distance between the operating body and the fingerprint identification area comprises:
detecting a target distance between an operating body and the fingerprint identification area by the first distance detection sensor;
and under the condition that the target distance detected by the first distance detection sensor is smaller than or equal to a first preset distance, detecting the target distance between the operating body and the fingerprint identification area through the second distance detection sensor.
And under the condition that the operating body is far away from the fingerprint identification area, namely the target distance is greater than the first preset distance, controlling the first distance detection sensor to be in an operating state and controlling the second distance detection sensor to be in a closed state. In a specific implementation, the distance between the operating body and the fingerprint identification area may be detected once by the first distance detection sensor every unit time, and the second distance detection sensor is turned on and the first distance detection sensor is turned off until the target distance is reduced to a first preset distance, so as to detect the target distance by the second distance detection sensor. In this embodiment, the operation power consumption of the first distance detection sensor is lower than the operation power consumption of the second distance detection sensor, so that long-time detection can be performed through the first distance detection sensor with lower power consumption, and the second distance detection sensor with high power consumption is prevented from operating for a long time and consuming a large amount of power, thereby reducing the power consumption of the terminal device.
In an implementation, the second distance detection sensor may be embodied as: a touch screen of the terminal device or an ultrasonic distance detection device. The power consumption of the second distance detection sensor is in milliampere level, and the detection distance is short due to the fact that the second distance detection sensor can detect the operation state that an operation body touches the touch screen, so that the target distance larger than the first preset distance cannot be accurately detected.
In addition, because the first distance detection sensor has low energy consumption, the distance detection accuracy is low due to the fact that distance detection needs to be performed once every unit time or the detection distance range is wide, and the detection accuracy is low.
In this embodiment, if the second distance detection sensor is a touch panel of the terminal device itself, the terminal device may include a device as shown in fig. 8, and the terminal device includes: a Central Processing Unit (CPU), a touch screen driving circuit, a touch screen, a proximity detection driving circuit, a proximity detection coil under the touch screen (also called a distance detection coil), an Organic Light-Emitting Diode (OLED) screen, and a screen fingerprint module (i.e. a fingerprint identification module).
The proximity detection driving circuit is used for driving the proximity detection coil under the screen to detect a target distance between the operating body and the fingerprint identification area under the control of the CPU and feeding the target distance back to the CPU; when the target distance received by the CPU is smaller than or equal to a first preset distance, sending control information to a touch screen driving circuit to drive a touch screen to display the fingerprint identification area; when the target distance received by the CPU is smaller than or equal to a second preset distance, corresponding control information is respectively sent to the OLED screen and the screen fingerprint module, so that the brightness of the OLED screen in the target area is improved, the screen fingerprint module is started, and fingerprint information is recognized in advance before the fingerprint is touched to the fingerprint recognition area.
In concrete application, the screen fingerprint module specifically can be optical fingerprint identification module, and it can acquire fingerprint information through the fingerprint image information who discerns.
In a specific application, the under-screen proximity detection coil may be a distance detection coil as shown in fig. 9, whose projection on the touch screen surrounds the fingerprint identification area. In this embodiment, in a process that a finger approaches a fingerprint identification area, a distance detection coil detects whether an orthographic projection of the finger on a touch screen is located under the touch screen in the proximity detection coil, and if the orthographic projection of the finger on the touch screen is located in the coil, a vertical distance between the finger and the touch screen corresponding to a surrounding area of the coil is detected, and when the distance is smaller than a preset first preset distance or a preset second preset distance, a trigger message is sent to a CPU through a proximity detection driving circuit to trigger the CPU to start the touch screen and a screen fingerprint module to execute a step corresponding to a target distance in an embodiment of the present invention, so as to implement each process in the fingerprint identification method provided in the embodiment of the present invention.
In a specific application, the distance detection coil and the operation body can form a capacitor;
the detecting, by the first distance detection sensor, a target distance between an operating body and the fingerprint identification area includes:
and determining a target distance between the operating body and the fingerprint identification area according to the electric parameter value of the capacitor.
Wherein the electrical parameter may be represented as: a capacitance value, a current value, or a voltage value. It should be noted that, when the electrical parameter represents a current value or a voltage value, the terminal device may calculate the capacitance value of the capacitor according to the current value or the voltage value.
It should be understood that the capacitance value of the capacitor is inversely related to the target distance, i.e. if the capacitance value of the capacitor is larger, the distance between the operating body and the fingerprint identification area is smaller.
In practical applications, in one implementation manner, the terminal device may obtain a corresponding relationship between the capacitance value and the target distance in advance. Thus, when the capacitance value of the capacitor is detected, the target distance corresponding to the capacitance value is determined by searching the corresponding relation.
In another implementation manner, the terminal device may obtain a calculation formula for calculating the target distance by using the capacitance value in advance. In this way, when the capacitance value of the capacitor is detected, the capacitance value can be input to the above calculation formula to calculate the target distance.
In the application, if the fingerprint identification module represents for ultrasonic fingerprint identification module, can be in when the target distance reduces to being less than or equal to the second and predetermineeing the distance, control ultrasonic fingerprint identification module transmission ultrasonic wave to acquire fingerprint information etc. through ultrasonic wave propagation time and speed. The process of controlling the fingerprint identification module to fingerprint the operating body is not limited.
It is thus clear that, be different from prior art, terminal equipment only detects under the condition of the touch-control operation of operation body to the fingerprint identification module, just control fingerprint identification module group the operation body carries out fingerprint identification, and the terminal equipment of this embodiment is in the target distance reduces to being less than or equal to under the condition of the second distance of predetermineeing, can control fingerprint identification module group fingerprint identification is to the operation body carries out fingerprint identification to the realization begins to polish or launch the ultrasonic wave before user's finger contacts the touch-control screen promptly, and opens the fingerprint identification module, has shortened the fingerprint identification time behind the user's touch-control screen, thereby has promoted fingerprint identification's efficiency.
What need explain, no matter the fingerprint identification module is optics fingerprint identification module or ultrasonic fingerprint identification module, is less than the second in the operating body and the fingerprint identification between regional target distance and predetermines under the condition apart from, polishes or launches the ultrasonic wave to the operating body in advance to start the fingerprint identification module in advance. Like this, be less than the time point of second preset distance at the target distance and to the operation body touch-control fingerprint identification between regional time point, certain time length will have, in this time length, the fingerprint identification module can carry out fingerprint information collection many times, gather multiframe fingerprint identification information promptly, and when the operation body touch-control was regional to fingerprint identification, select most clear or most accurate fingerprint information and carry out fingerprint verification, with the time length at the fingerprint identification that reduces, can also promote fingerprint identification and fingerprint verification process's accuracy simultaneously.
In the embodiment provided by the invention, the target distance between the operating body and the fingerprint identification area is acquired; displaying the fingerprint identification area under the condition that the target distance is smaller than or equal to the first preset distance and larger than a second preset distance, wherein the second preset distance is smaller than the first preset distance; and under the condition that the target distance is reduced to be less than or equal to a second preset distance, controlling the fingerprint identification module to perform fingerprint identification on the operation body. Like this, can inform the regional position of user's fingerprint identification when the user will point near fingerprint identification regional to reduce the degree of difficulty of fingerprint identification process, and when its finger is further close to fingerprint identification regional, open the fingerprint identification module in advance and carry out fingerprint identification, in order to reduce the fingerprint identification time behind the touch fingerprint identification region, thereby shortened fingerprint identification's time, promoted the efficiency of fingerprint identification method.
