It is understood that in the above embodiments, the peripheral interface 104, the processor 103, and the memory controller 102 may be implemented in a single chip. Alternatively, in the above-described embodiments, they may be implemented by separate chips, respectively.

In particular, the touch screen 108 displays video output to the user, the content of which may include text, graphics, video, and any combination thereof. Some of the output results are for some of the user interface objects.

The space detection sensor 111 is used for detecting whether an operator exists above the touch display screen or not and acquiring detection data of the operator so as to determine that the operator is mapped to an operation area on the touch display screen based on the detection data.
The space-isolation detection sensor 111 may be an antenna module having millimeter wave transmitting and receiving functions, where the millimeter wave generally refers to an electromagnetic wave with a frequency band of 30 to 300GHz and a corresponding wavelength of 1 to 10mm, and its operating frequency is between microwave and far-infrared wave, so that it has two spectrum characteristics. Millimeter waves can be used for millimeter wave communication, which is communication performed by using millimeter waves as carriers for transmitting information, and the millimeter waves belong to a very high frequency band, and are propagated in space in a direct wave manner, and have narrow beams and good directivity. Advantages of millimeter wave communication include: extremely wide bandwidth, narrow beam, strong detection capability, good security, high transmission quality, small element size and the like.
Simultaneously, the millimeter wave can also be used for millimeter wave imaging, and the millimeter wave imaging mode mainly has two kinds: one is passive millimeter wave imaging and the other is active millimeter wave imaging. The passive millimeter wave imaging utilizes the millimeter waves emitted by the human body to carry out imaging, and has good imaging effect outdoors; the active millimeter wave imaging principle is similar to the action of a flash lamp of a camera, and the active millimeter wave imaging principle emits a millimeter wave source to an object to be detected and detects the field intensity reflected by the object for imaging.
Specifically, the active millimeter wave imaging may use a holographic imaging principle, utilize a millimeter wave coherence principle, record a diffraction pattern of each scattering point on the target by collecting spatial interference fringes, and finally obtain a millimeter wave image of the target by image reconstruction. The imaging process comprises the following steps: the system receives echoes of each frequency point in a bandwidth in sequence to obtain spatial three-dimensional data, then transforms the data to a spatial frequency domain through Fourier transform, namely, the echoes are expressed into superposition of plane waves with different azimuth angles and pitch angles and different wave numbers in a certain range, then each plane wave component is inverted to actual three-dimensional distance distribution of a target through phase compensation, and finally, a three-dimensional image is obtained through taking a model after three-dimensional inverse Fourier transform.
Wherein, above-mentioned antenna module group can adopt the millimeter wave antenna of multiple type, for example: (1) the horn antenna is widely applied to microwave and millimeter wave bands due to the characteristics of simple structure, wide frequency band, easy manufacture, convenient adjustment and the like; (2) microstrip antennas, microstrip antennas or printed antennas, were widely used at the earliest in the centimeter band and subsequently extended to the millimeter band; (3) leaky-wave antennas, which radiate energy due to some discontinuities when electromagnetic waves are transmitted along an open structure, are called leaky-wave antennas.
The fingerprint area determination method in the embodiment of the present application is described based on the terminal described above.
Please refer to fig. 2, which is a flowchart illustrating a method for determining a fingerprint area according to an embodiment of the present application, the method includes:
in the embodiment of the present application, the fingerprint area determination method described above is implemented by a fingerprint area determination device (hereinafter, simply referred to as a determination device), which is a program module and stored in a readable storage medium of a terminal, and a processor in the terminal can call the determination device in the readable storage medium to implement the fingerprint area determination method described above.
It should be noted that the terminal related in this embodiment of the application includes a touch display screen, that is, the touch screen 108 shown in fig. 1, and a fingerprint identification module and an air-gap detection sensor are disposed below the touch display screen, where the fingerprint identification module may be fully opened or partially opened, for example, a fingerprint identification function of the entire touch display screen may be opened, so that input fingerprint data may be acquired when a fingerprint input operation is performed in any one area of the touch display screen, or the fingerprint identification function of any one area of any size of the touch display screen may be opened, so that input fingerprint data may be acquired only when a fingerprint input operation is performed in the area. The detection range of the space detection sensor is directly above the touch display screen, and when a user needs to perform a fingerprint input operation on the touch display screen, an operator (such as a thumb or other finger) needs to enter a space range directly above the touch display screen and then fall onto the touch display screen.
In the embodiment of the present application, there are various holding operations, for example, a left-hand holding operation, a right-hand holding operation, or a two-hand holding operation, and it can be understood that in a left-hand holding operation state, the operation is usually performed on the touch display screen by a thumb of a left hand, in a right-hand holding operation state, the operation is usually performed on the touch display screen by a thumb of a right hand, and in a two-hand holding operation state, the operation is performed on the touch display screen by a thumb of the left hand or a thumb of the right hand, wherein the detection of the holding operation can be detected by a contact sensor arranged on the back of the terminal (a borderless terminal), or on the back and the side of the terminal (a borderless terminal). The touch sensor may be a pressure sensor, an ultrasonic sensor or an infrared sensor, and it can be understood that there are various ways to detect the holding operation, and in practical applications, a required way may be selected for detection, which is not described herein.
In the embodiment of the application, when the determining device detects a holding operation on the terminal, the space detection sensor corresponding to the terminal is started based on the holding operation, for example, if the holding operation is detected as a one-hand holding operation, it may be determined that a thumb of one hand touches a movable area on the display screen in a scene of the one-hand holding operation, and the space detection sensor whose detection range includes the movable area is determined and is turned on as the space detection sensor corresponding to the one-hand holding operation. Or, if the holding operation of both hands is detected, the movable regions corresponding to the two thumbs of both hands may be determined respectively, and based on the movable regions corresponding to the two thumbs, the space detection sensors whose detection ranges respectively include the corresponding movable regions, or the space detection sensors whose detection ranges simultaneously include the movable regions corresponding to the two thumbs, may be determined, and the corresponding space detection sensors may be turned on. In order to better understand the technical solution in the embodiment of the present application, please refer to fig. 3, which is a schematic diagram of a one-handed holding operation in the embodiment of the present application, and in fig. 3, a left-handed holding operation performed on a smartphone is described as an example, where the front of the smartphone is a touch display screen, after the left-handed holding operation is detected, a movable region of a thumb of a left hand may be determined, and none of non-movable regions except the movable region of the touch display screen is touched, that is, an isolation detection sensor whose detection range includes the movable region may be activated, so that a position of the thumb above the movable region may be located by the isolation detection sensor.
It should be noted that the layout of the space detection sensor below the touch display screen needs to be set according to the performance of the space detection sensor itself, the size of the touch display screen, and the requirement on the detection accuracy, and is not limited here. And it can be understood that if the detection range of one space detection sensor can cover the whole touch display screen of the terminal, one space detection sensor can be arranged, and in such a scene, it is not necessary to determine the movable area of the thumb and determine which space detection sensor to turn on based on the movable area.
step 203, determining an operation area of the operation object mapped on the touch display screen according to the detection data, starting a fingerprint identification function of the operation area, and taking the operation area as a fingerprint area.
In the embodiment of the application, after the determination device starts the air-space detection sensor, the air-space detection sensor will detect whether the operator exists in the detection range of the air-space detection sensor, and acquire the detection data of the operator in the detection range of the air-space detection sensor in real time, wherein the detection range is located above the touch display screen.
The determining device further determines an operation area of the operation object mapped on the touch display screen according to the detection data, starts a fingerprint identification function of the operation area, and takes the operation area as a fingerprint area.
In the embodiment of the present application, since it is necessary to determine a fingerprint area, and perform a fingerprint input operation in the fingerprint area so as to obtain fingerprint data for triggering a corresponding function, when a holding operation on the terminal is detected, the determining device further determines whether a current state of the terminal is a to-be-input fingerprint state, and it can be understood that the to-be-input fingerprint state refers to a state that the terminal needs to be triggered to perform a next process by inputting fingerprint data, for example: when the terminal is in the screen-locked state, or when the terminal is in a state that fingerprint verification needs to be performed to perform fingerprint payment, therefore, in step 201, before the blank detection sensor is turned on, it may be further determined whether the terminal is in a fingerprint state to be input, or before the fingerprint identification function of the operation area is started, it may be further determined whether the terminal is in a fingerprint state to be input, and if so, the fingerprint identification function of the operation area is turned on.
In the embodiment of the application, the operation object is detected by using the space detection sensor, so that before the operation object inputs a fingerprint, a mapping operation area of the operation object on the touch display screen can be detected, the probability that the operation area is an area where a user inputs the fingerprint is high, the fingerprint identification function of the area is started, the fingerprint area can be consistent with the operation area mapped by the operation object, and the power consumption generated by starting the fingerprint identification function is effectively reduced on the premise that fingerprint identification can be realized.
To better understand the technical solution in the embodiment of the present application, on the basis of the embodiment shown in fig. 2, please refer to fig. 4, which is another schematic flow chart of the fingerprint determination method in the embodiment of the present application, including:
402, acquiring detection data of an operator above the touch display screen in real time by using an air-separation detection sensor;
in the embodiment of the present application, the content of the above steps 401 and 402 is similar to the content described in the steps 201 and 202 in the embodiment shown in fig. 2, and specifically, the embodiment shown in fig. 2 may be referred to, and is not limited herein.
it is to be understood that there are various types of the space detection sensor, and a sensor capable of detecting an operator above the touch display screen may be used as the space detection sensor. Two kinds of the space detection sensors will be described below.
In a feasible implementation manner, the space detection sensor is an antenna module having millimeter wave transmitting and receiving functions, the antenna module may be disposed below the touch display screen, and one or more groups may be set based on a preset requirement, and if a group of antenna modules may detect an area of the entire touch display screen, one group may be used. It is understood that the farther the path of millimeter wave propagation is, the larger the power variation value of millimeter wave is, and the closer the path of millimeter wave propagation is, the smaller the power variation value of millimeter wave is.
The millimeter waves transmitted by the antenna modules are transmitted in a scattering mode, the millimeter waves can be transmitted to a conical area formed by the preset divergence angle by using the antenna modules as the center through one group of antenna modules, and the reflected routes of the millimeter waves are consistent with the transmitted routes when the millimeter waves are reflected.
When spacing detection sensor is above-mentioned antenna module, detection data then includes: the power change value reflected by each reflection point on the operation object and the first reflection angle.
The millimeter waves emitted by the antenna module to the emittable area can be regarded as one millimeter wave uniformly emitted in each direction in the emittable area, and each reflected millimeter wave is reflected after being transmitted to a certain point on the operator, so that the power change value of the millimeter waves emitted back in each direction corresponds to one point on the operator, and the point can be called as a reflection point.
That is, the power variation value transmitted by each reflection point on the operation object may be understood as the power variation of a millimeter wave after the millimeter wave is reflected and reflected back to the antenna module when the millimeter wave is transmitted to the reflection point on the operation object. Namely, the power change value is the power change of the millimeter waves reflected by the reflection point after the millimeter waves are transmitted to the surface of the touch display screen by the antenna module.
The first reflection angle may be an included angle formed between a route of the reflection point reflecting the millimeter waves and the touch display screen. The included angle may be calculated based on the installation position of the antenna module below the touch display screen and the included angle of the center line of the transmission relative to the touch display screen, which is not described herein again.
Further, the step 403 may specifically include the following steps:
step A, calculating a first linear distance of each reflection point by using the power change value of each reflection point, wherein the first linear distance represents the distance between the reflection point and the antenna module;
and step B, drawing the graph of the operator according to the first straight line distance and the first reflection angle of each reflection point, and determining the position information.
In the embodiment of the present application, when the air-separation detection sensor is an antenna module having a function of transmitting and receiving millimeter waves, the determination device calculates a first linear distance of each reflection point by using a power variation value of each reflection point on the operation object, where the first linear distance represents a distance between the reflection point and the antenna module.
It is understood that the closer the millimeter wave propagates, the smaller the power variation value, and the farther the millimeter wave propagates, the larger the power variation value, that is, the above power variation value is related to the distance, and furthermore, the power attenuation coefficient of the millimeter wave during transmission may be a preset coefficient value, so the above first linear distance may be calculated according to the following formula:
wherein S represents a first linear distance, P represents a power variation value, and P represents a power variation valuerRepresenting the power change caused when a reflection point is transmitted, and k represents the power attenuation coefficient. It is understood that the above PrCan be preset or, for the case of very small attenuation variations, this PrThe value of (c) is negligible.
In the embodiment of the application, after the first linear distance of each reflection point and the first reflection angle of each reflection point are obtained, the graph of the operator is drawn according to the first linear distance and the first reflection angle of each reflection point, and the position information of the operator when the operator is vertically mapped to the touch display screen is determined.
Specifically, the method comprises the following steps: the determining device can determine a first vertical distance from each reflection point to the touch display screen and a first coordinate value when each reflection point is vertically mapped to the touch display screen by using the first linear distance and the first reflection angle of each reflection point, it is understood that the right triangle principle is used herein, and for the convenience of understanding, please refer to fig. 5, which is a schematic diagram of the reflection point in the embodiment of the present application, in fig. 5, point a represents a reflection point on the operating object, point B represents the antenna module, point C represents a corresponding point on the touch display screen when point a is vertically mapped to the touch display screen, in a right triangle formed by the points ABC, AB represents a first linear distance of the reflection point a, angle D represents a first reflection angle of the reflection point a, AC represents a first vertical distance from the reflection point a to the touch display screen, and a coordinate value of the point C on the touch display screen is a first coordinate value when the reflection point a is vertically mapped to the touch display screen.
Further, the determination means draws a three-dimensional figure of the operator using the first vertical distance of each reflection point, and sets the first coordinate values of each reflection point as the position information. It is understood that the operation object is an object having a shape, such as a thumb, the first vertical distances of the reflection points on the operation object may be the same or different, and since the reflection points are located on the surface of the operation object, the surface of the operation object opposite to the touch display screen may be drawn based on the first vertical distances of the reflection points, i.e. a three-dimensional figure of the operation object may be obtained. The set of first coordinate values of the respective reflection points represents a maximum edge of the three-dimensional figure of the operator.
It is to be understood that, in order to further determine whether the operator is an operator for performing a fingerprint input operation, the obtained graph of the operator may be matched with each thumb graph template in a preset thumb graph set, wherein the preset thumb graph set includes graphs formed under different postures of the thumb when the thumb is above the touch display screen. The method comprises the steps of obtaining the similarity between a graph of an operator and each thumb graph template in a thumb graph set through a matching mode, extracting the maximum similarity, determining that the graph of the operator is a thumb graph when the maximum similarity is larger than a preset similarity threshold, further determining that the operator is a thumb, determining an area formed by vertically mapping the operator to position information of a touch display screen as an operation area when the graph of the operator is determined to be the thumb graph, starting a fingerprint identification function in the operation area, and taking the area as a fingerprint area.
It should be noted that, when a fingerprint is input by a thumb, the fingerprint is input by using a face without a nail on a first section of the thumb, please refer to fig. 6, which is a schematic diagram of a hand in an embodiment of the present application, and fig. 6 is a schematic diagram of a scene in which a fist is held and the thumb is set up, and shows a position of the first section of the thumb. In order to more accurately determine the area related to the actual fingerprint input operation on the touch display screen, the determining device extracts a thumb graphic template corresponding to the maximum similarity and determines the area for inputting the fingerprint in the thumb graphic template; the area for inputting the fingerprint is an area corresponding to a first section of a thumb, and further, from an area formed by mapping the operation object to position information on the touch display screen, an area corresponding to the area for inputting the fingerprint is extracted as an operation area, a fingerprint identification function in the operation area is started, and the operation area is used as a fingerprint area. It can be understood that, in the case that the operator is a thumb, the above technical solution may be understood that the thumb first section is tracked through the space detection sensor, and the thumb first section is vertically mapped to the area formed on the touch display screen to be used as the fingerprint area, so that the size of the area for activating the fingerprint identification function can be further reduced, and the power consumption can be further reduced.
It is to be understood that, while the above-mentioned related contents are that the space detection sensor is an antenna module, the following describes a possible implementation manner of the above-mentioned step 403 when the space detection sensor is a proximity sensor.
The proximity sensor may be a sensor having functions of emitting and receiving infrared rays, the proximity sensor may be disposed under the touch display screen, and one or more groups may be disposed based on a preset requirement, and if one group of the proximity sensor can detect the whole area of the touch display screen, one group may be used, in this embodiment, a group of the proximity sensor is taken as an example, the proximity sensor may emit infrared rays, and when the infrared rays are emitted to an operator, the operator reflects the infrared rays, so that the infrared rays received by the proximity sensor are all reflected infrared rays, and the proximity sensor will record the emitting time point of the emitted infrared rays and the receiving time point of the reflected infrared rays, and since the propagation speed of the infrared rays is fixed, the proximity sensor may be based on the emitting time point, the receiving time point, and the propagation speed of the infrared rays, the distance traveled by the infrared from transmission to reception is determined.
The infrared rays emitted by the proximity sensor can be sent in a scattering mode, and can be emitted in a conical area formed by a preset divergence angle by taking the proximity sensor as a center, wherein one infrared ray emitting route is the same as the route reflected by the infrared ray emitting route, and the angle of the infrared ray emitted or received by the proximity sensor can be recorded. It is understood that the infrared rays emitted by the proximity sensor into the emittance area can be regarded as a strip of infrared rays uniformly emitted in all directions in the emittance area, and each strip of reflected infrared rays is reflected after being transmitted to a point on the operating object, so that the infrared rays reflected in each direction correspond to a point on the operating object, which can be called as a reflection point.
In the embodiment of the present application, when the space detection sensor is a proximity sensor, the detection data includes: and the second linear distance is the distance from each reflecting point sensed by the proximity sensor to the proximity sensor, and the second reflection angle is an included angle formed by the direction of the second distance value and the touch display screen.
Wherein, the proximity sensor can be obtained by directly calculating the emission time point, the receiving time point and the propagation speed of the infrared ray corresponding to a certain reflection point, specifically, the emission time point is subtracted from the receiving time point, the obtained time difference is the propagation time of the infrared ray, since the infrared ray is emitted and reflected back, the same route is transmitted twice, when the distance from the reflection point to the proximity sensor is calculated, the actual time is half of the time difference, and the half time difference is multiplied by the propagation speed, the obtained value is the second straight line distance of the reflection point, wherein, the second reflection angle can be obtained by the emission angle of the infrared ray, the included angle between the center line of the emittable area and the touch display screen when the proximity sensor is installed below the touch display screen, for example, if the center line of the emittable area of the proximity sensor is perpendicular to the surface of the touch display screen, and the emission angle of the infrared ray is an angle formed by the infrared ray and the central line, the second reflection angle may be 90 degrees minus the emission angle of the infrared ray.
Further, the step 403 may specifically include the following steps:
step C, determining a second vertical distance from each reflection point to the touch display screen and a second coordinate value when each reflection point is vertically mapped to the touch display screen by using the second linear distance and the second reflection angle of each reflection point;
and D, drawing a three-dimensional graph of the operator by using the second vertical distance of each reflection point, and taking the set of the second coordinate values of each reflection point as position information.
In the embodiment of the present application, the determining device may determine, by using the second linear distance and the second reflection angle of each reflection point, a second vertical distance from each reflection point to the touch display screen and a second coordinate value when each reflection point is vertically mapped to the touch display screen, it can be understood that the right triangle principle is used herein, and is consistent with the calculation manner of the scene introduced in fig. 5, taking fig. 5 as an example, when the gap detection sensor is a proximity sensor, AB represents the second linear distance from the reflection point to the proximity sensor, angle D represents the second reflection angle of the reflection point a, AC represents the second vertical distance from the reflection point a to the touch display screen, and the coordinate value of the point C on the touch display screen is the second coordinate value when the reflection point a is vertically mapped to the touch display screen.
Further, the determination means draws a three-dimensional figure of the operator using the second vertical distance of each reflection point, and sets the first coordinate values of each reflection point as the position information. It is understood that the operation object is an object having a shape, such as a thumb, the second vertical distance of each reflection point on the operation object may be the same or different, and since each reflection point is located on the surface of the operation object, the surface of the operation object opposite to the touch display screen may be drawn based on the second vertical distance of each reflection point, i.e. a three-dimensional figure of the operation object may be obtained. The set of second coordinate values of the respective reflection points represents a maximum edge of the three-dimensional figure of the operator.
It is to be understood that, in order to further determine whether the operator is an operator for performing a fingerprint input operation, the obtained graph of the operator may be matched with each thumb graph template in a preset thumb graph set. Through a matching mode, the similarity between the graph of the operator and each thumb graph template in the thumb graph set can be obtained, the maximum similarity is extracted, when the maximum similarity is larger than a preset similarity threshold value, the graph of the operator is determined to be a thumb graph, the operator can be further determined to be a thumb, when the graph of the operator is determined to be the thumb graph, an area formed by vertically mapping the operator to the position information of the touch display screen is determined to be an operation area, a fingerprint identification function in the operation area is started, and the operation area is used as a fingerprint area.

It can be understood that, in the case that the operator is a thumb, the above technical solution may be understood that the thumb first section is tracked through the space detection sensor, and the thumb first section is vertically mapped to the area formed on the touch display screen to be used as the fingerprint area, so that the size of the area for activating the fingerprint identification function can be further reduced, and the power consumption can be further reduced.
In this embodiment of the application, the determining device may further display the fingerprint area on the touch display screen in a manner of displaying a preset graphic, so as to indicate the fingerprint area where the user can currently perform the fingerprint input operation, which is convenient for the user to operate. For example, if the touch display screen currently displays a fingerprint payment interface and the user is required to perform a fingerprint input operation to perform a payment process, the determining device may display a fingerprint graphic in a fingerprint area on the touch display screen to instruct the user to perform the fingerprint input operation in the fingerprint area by using a thumb so as to complete the payment, or, if the touch display screen is currently in a screen-locking and screen-lighting state, may display an unlocking identifier in the fingerprint area of the touch display screen to instruct the user to perform the fingerprint input operation in the fingerprint area by using the thumb so as to complete the unlocking.
