The foregoing and other aspects, features, and advantages of the present application will become more apparent in light of the following detailed description when taken in conjunction with the accompanying drawings.

Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely exemplary of the application, which can be embodied in various forms. Well-known and/or repeated functions and constructions are not described in detail to avoid obscuring the application with unnecessary or excessive detail. Therefore, specific structural and functional details disclosed herein are not intended to be limiting, but merely serve as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present application in virtually any appropriately detailed structure.

The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments as per the application.

An electronic device is provided in this embodiment, fig. 1 is a schematic structural diagram of the electronic device in this embodiment, fig. 2 is a schematic structural diagram of a first sensing area in this embodiment, and referring to fig. 1 and fig. 2, the electronic device in this embodiment may include a fingerprint sensor and a processor.

The fingerprint sensor is provided with a plurality of first sensing areas, and the intervals among the first sensing areas are arranged in the acquisition area of the fingerprint sensor.

The processor is configured to: if the presence of an operating body is determined through the first sensing values of the plurality of first sensing areas, obtaining second sensing values of the plurality of first sensing areas at least twice based on a target acquisition period, and determining the movement of the operating body relative to the acquisition area based on at least two second sensing values.

Alternatively, the collection area of the fingerprint sensor may be disposed at any location of the electronic device. For example, the side of the electronic device may be provided with a power key, and the fingerprint sensor may be integrated on the power key. The acquisition region may be formed by a surface of a power key. It will be appreciated that the power key may also be located near the lower edge of the display. Alternatively, the fingerprint sensor is also integrated on a volume condition key on the side of the electronic device. Alternatively, the fingerprint sensor may be disposed on a side or a back side of the electronic device, or the like.

Optionally, the plurality of first sensing areas may be uniformly arranged in the collecting area at equal intervals. For example, the fingerprint sensor may include m×k sensing units, where M and K are positive integers. The M x K sensing units can be arranged in an array manner in the acquisition area to form a sensing array. The fingerprint sensor can acquire fingerprint images based on the induction values of the M multiplied by K induction units, and fingerprint identification is performed based on the fingerprint images. On the basis, H×L sensing units can be selected from the sensing arrays formed by the M×K sensing units to serve as first sensing arrays, P×Q uniformly arranged first sensing arrays can be selected from the sensing arrays in total, and the corresponding area of each first sensing array serves as a first sensing area. Wherein, H, L, P and Q are both positive integers.

Alternatively, the sensing unit may include, but is not limited to, a capacitive sensor, an optical sensor, an ultrasonic sensor, and the like. Taking the sensing unit including the capacitive sensors as an example, m×k capacitive sensor arrays may be arranged in the sampling area, and a subarray formed by h×l capacitive sensors may be selected as the first sensing array.

Optionally, the first sensing value and the second sensing value may include sensing values of sensing units such as a capacitive sensor, an optical sensor, and an ultrasonic sensor, where the sensing values can represent a distance and/or a pressure between a sub-region of the first sensing region and a surface of the operating body, and the sub-region is a region opposite to the sensing unit in the first sensing region. For example, the capacitance values of the h×l capacitive sensors in the first sensing array may be regarded as the first sensing value, where the first sensing value actually includes a set of capacitance values.

Optionally, the first sensing value and the second sensing value may also include a first processing value formed based on processing sensing values of sensing units such as a capacitive sensor, an optical sensor, an ultrasonic sensor, and the like, where the first processing value can represent an average distance and/or an average pressure between the first sensing region and a surface of the operating body. Also for example, an average value of capacitance values of h×l capacitance sensors in the first sensing array may be calculated, and the average value may be taken as the first sensing value.

Alternatively, a plurality of the first sensing regions may be configured to acquire a first sensing value according to a target acquisition period, and determine whether an acquisition region has an operation body present based on the first sensing value. For example, a first threshold value corresponding to the first sensing value may be preset, and when the first sensing value is greater than the first threshold value, it may be determined that a first sensing region corresponding to the first sensing value, or a sub-region of the first sensing region corresponding to the first sensing value has an operation body presence. Also for example, it may be determined whether an operator is present in the acquisition area based on the first sensing value by a preset operator sensing algorithm. The method of determining whether the acquisition region has the presence of the operation body is not limited herein, and in actual application, whether the acquisition region has the presence of the operation body may be determined based on the first sensing value by various methods. It will be appreciated that the operating body may comprise a finger of the user, possibly other parts of the user, or possibly other objects.

Optionally, the second sensing value of the plurality of first sensing regions may be different from the first sensing value of the plurality of first sensing regions at least twice. For example, the sensing values of the plurality of first sensing regions at the N-2 th acquisition period may be referred to as first sensing values. In the case where it is determined that the sampling region has the presence of the operating body based on the first sensing values, the sensing values of the plurality of first sensing regions at the N-1 th acquisition period and the N-th acquisition period may be referred to as second sensing values.

Alternatively, one of the second sensing values of the at least two first sensing regions may be the same as the first sensing value of the plurality of first sensing regions. For example, the sensing values of the plurality of first sensing regions at the N-2 th acquisition period may be referred to as first sensing values. In the case that the sampling area is determined to have the operation body present based on the first sensing value, sensing values of the plurality of first sensing areas in the N-2 th and N-1 th acquisition periods may be respectively taken as second sensing values.

It will be appreciated that in practice, the acquisition of the second sensing values of the plurality of second sensing regions in two acquisition cycles is not limited to the acquisition of the second sensing values of three, four or more consecutive or non-consecutive acquisition cycles.

Optionally, when determining that the operating body exists based on the first sensing values of the plurality of first sensing regions, the second sensing values of the plurality of first sensing regions may be acquired at least twice according to the target acquisition period, and movement of the operating body may be determined based on the at least two second sensing values. Then, a control instruction for controlling the electronic device to perform the target operation corresponding to the movement of the operation body may be generated. For example, in the event that it is determined that the sampling area has an operator present and that the operator is moving relative to the sampling area, control instructions for controlling a target application on an electronic device to perform a target operation may be generated.

According to the electronic device, the sampling area of the fingerprint sensor is provided with the plurality of first sensing areas, whether the sampling area is provided with an operation body or not can be determined based on the first sensing values of the plurality of first sensing areas, and movement of the operation body relative to the sampling area can be determined based on the at least twice second sensing values of the plurality of first sensing areas. Therefore, the fingerprint sensor can be used for detecting the movement of the operating body, a feasible implementation mode is provided for the operation control of the electronic equipment, the operation process is simple, the implementation is easy, and the stability and the robustness are high.

In some embodiments, the processor is further configured to:

control coordinates for controlling a display content change of a screen of the electronic device corresponding to movement of the operation body are generated by a first processing mode based on a first trigger instruction.

Wherein the first processing mode corresponds to a determination of movement of the operating body by the plurality of first sensing areas of the fingerprint sensor.

Alternatively, the processor may be in the first processing mode by default, and in response to the first trigger instruction, control coordinates corresponding to movement of the operation body may be generated by the first processing mode, and display content of a screen of the electronic device may be controlled to be changed by the control coordinates.

Optionally, the processor may also switch to the first processing mode in response to the first trigger instruction. And, in a case where it is determined that an operating body is present based on the first sensing values of the plurality of first sensing regions, generating control coordinates corresponding to the movement of the operating body based on the determined movement of the operation with respect to the acquisition region by the first processing mode. For example, the processor may default to a second processing mode, and the processor may generate a first trigger instruction in response to a target application program operation, and switch to the first processing mode based on the first trigger instruction.

Alternatively, the processor may determine movement information for characterizing movement of the operation body with respect to the acquisition area based on at least two second sensing values, and may generate control coordinates based on the movement information through the first processing mode, and control display content change of a screen of the electronic device through the control coordinates.

Optionally, the processor may be configured to generate control coordinates conforming to a target protocol based on the movement information through the first processing mode. In the case of the electronic device having a touch screen, the processor may also generate control coordinates conforming to the target protocol based on movement of the operator relative to the touch screen. Therefore, the consistency design of the control instructions of the fingerprint sensor and the touch screen can be realized, the development difficulty of a target application program is simplified, and the application range of application program control based on the movement of an operating body in a sampling area of the fingerprint sensor is widened.

Alternatively, the display content of the screen of the electronic device may include various display contents displayed on the screen of the electronic device. The display may include a system interface of an operating system, such as a desktop, a taskbar, a setup interface, and the like. The display content may also include an application program interface.

For example, the electronic device may generate a first trigger instruction in response to initiation of a camera program to trigger the processor to switch to a first processing mode. In the case where the movement of the operation body has been determined based on at least two second inductions, control coordinates for controlling the focal length of the camera may be generated by the first processing mode.

In some embodiments, the processor is specifically configured to:

Optionally, the contact event may be used to indicate that the operating body is in contact with the acquisition region, and the exit event may be used to indicate that the operating body is in a disengaged state from the sampling region. On this basis, the second sensing values of the plurality of first sensing regions may be continuously acquired based on a target acquisition period in response to the contact event, and the moving direction of the operation body with respect to the acquisition region may be continuously determined based on the second sensing values of the plurality of first sensing regions adjacent at least twice.

For example, the target acquisition period may be T1, and a set of second sensing values of the plurality of first sensing regions are acquired at intervals of T1, and a moving direction of the operation body with respect to the acquisition region is determined at intervals of T1 based on the second sensing value of the current acquisition period and the second sensing value of at least one acquisition period preceding the current acquisition period.

Alternatively, one coordinate in the display area of the screen may be stored as the reference coordinate in advance. The processor may obtain the reference coordinates and take them as starting coordinates in response to a touch event. For example, the center point coordinates of the display area of the screen may be set as reference coordinates in advance, and the center point coordinates may be acquired from a memory or a register as start coordinates when a touch event is acquired.

Alternatively, the processor may determine the start coordinates of the display area belonging to the screen based on the relative positional relationship between the operation body and the acquisition area in response to the contact event. For example, a correspondence relationship between a display area of a screen and the acquisition area may be preset. In the case where it is determined that the acquisition region has the operation body present, the relative positional relationship between the operation body and the acquisition region may be determined based on the second sensing value. And then, determining the initial coordinates based on the relative position relation between the operation body and the acquisition area and the corresponding relation between the display area of the screen and the acquisition area.

Alternatively, in the case of determining the moving direction and the start coordinate of the operation body, the processor may construct one target coordinate every interval of the target acquisition period based on the start coordinate and the moving direction. In the case where there is already a constructed target coordinate in the previous acquisition cycle, the target coordinate of the current acquisition cycle may be constructed based on the moving direction determined in the current acquisition cycle and the target coordinate constructed in the previous acquisition cycle. For example, in a first acquisition cycle, the target coordinates for the first acquisition cycle may be constructed based on the start coordinates and the direction of movement. In the second acquisition period, the target coordinates of the second acquisition period may be constructed based on the movement direction determined in the second acquisition period and the target coordinates constructed in the first acquisition period.

Alternatively, a fixed value may be pre-stored, which is used to characterize the relative step sizes of the two adjacent acquisition periods. The processor may be configured to construct an nth target coordinate by adding a fixed value based on the nth-1 target coordinate. And during the 1 st acquisition period, adding a fixed value on the basis of the initial coordinate to construct the 1 st target coordinate.

Optionally, a relative position relationship between the operation body and the acquisition region in each acquisition period may be determined, a relative displacement between the operation body and the acquisition region may be determined based on the relative position relationship between at least two acquisition periods, and the target coordinate may be determined based on the relative displacement, the start coordinate and the movement direction.

In practical applications, the target coordinates may also be determined based on the fixed values and the relative positional relationship. For example, in the case where a relative displacement of two adjacent acquisition cycles can be acquired, the target coordinates of the current acquisition cycle may be determined based on the relative displacement. In the event that the relative displacement of two adjacent acquisition cycles is not effectively identified, the target coordinates of the current acquisition cycle may be determined based on the fixed value.

Alternatively, the direction information may be used to identify the direction of movement. The moving distance and moving direction of the display object of the display area may be controlled based on each of the start coordinate and the target coordinate and the direction information. It should be understood that the display object in the display area moves in the direction indicated by the direction information, and the changing of the display position of the display object should be broadly understood to include various movement modes such as translation, gathering movement, radioactive movement, and rotation movement.

Alternatively, the display object of the display area may include any display object in display content of a screen of the electronic device. The display object may comprise any one of a system interface or an application interface of the electronic device. For example, the display object may be an image captured by a camera displayed in a display interface of a camera program. When the focal length of the camera is adjusted by using the fingerprint sensor, the image shot by the camera is actually moved toward the center or radially away from the center with the center point of the display interface or with the focus point as the center.

Optionally, the processor may be configured to: if a first number of acquisition cycles or a first duration of succession is continued, it is determined that the acquisition zone has no operational body based on the first sensing values of the plurality of first sensing zones, a departure event is obtained. Of course, the processor may also be configured to: a departure event is obtained if no operator is sensed based on the second sensed values of the plurality of first sensed regions for a first number of consecutive acquisition cycles or a first duration of consecutive acquisition cycles.

In some embodiments, the processor is specifically configured to:

It will be appreciated that the second sensing value can be indicative of an average distance and/or an average pressure between the first sensing region and the surface of the operating body. The finger surface is typically in the form of a convex arc, and the average distance and/or average pressure between different areas of the finger surface and the respective first sensing areas is typically different when the finger touches the acquisition area. When the relative position relationship between the finger and the acquisition area is different, the second sensing values of the plurality of first sensing areas are different. When the finger is relatively displaced relative to the acquisition area, the second sensing values of the two groups of the plurality of first sensing areas acquired before and after the finger moves are different. On the basis, two groups of second sensing values of the plurality of first sensing areas can be obtained, the two groups of second sensing values are compared, and the moving direction of the operation body relative to the acquisition area is determined.

Alternatively, the first time instant and the second time instant may be in different acquisition periods. For example, the second sensing values of the plurality of first sensing regions in the N-1 acquisition cycle may be obtained, and the italic values in fig. 3a are the second sensing values of the respective first sensing regions in the N-1 acquisition cycle. The second sensing values of the plurality of first sensing regions in the nth acquisition period may also be obtained, and the italic numerical values in fig. 3b are the second sensing values of the first sensing regions in the nth acquisition period. And comparing the second sensing values obtained in the N-1 acquisition period with the second sensing values obtained in the N acquisition period to determine the moving direction of the operation body relative to the acquisition area.

Alternatively, the direction recognition model may be constructed in advance. For example, the direction recognition model may be built in advance based on a machine learning model. In practical application, the direction recognition model can be used for comparing the plurality of second sensing values at the first moment with the plurality of second sensing values at the second moment to determine the moving direction of the operation body relative to the acquisition area.

In some embodiments, the processor is specifically configured to:

enabling a second sensing region of the fingerprint sensor if it is determined that an operating body exists through first sensing values of the plurality of first sensing regions; wherein the second sensing region comprises between the first sensing regions; the second sensing areas have higher precision than each first sensing area;

Alternatively, the second sensing region may comprise the entire area of the acquisition region. Illustratively, still taking as an example that the fingerprint sensor includes m×k sensing units, the fingerprint sensor may include p×q first sensing arrays, each of which may include h×l sensing units. The second sensing region may comprise all of the acquisition region, i.e. the second sensing region comprises M x K sensing units. Since the area of the second sensing area and the number of sensing units are larger than those of the first sensing areas, the accuracy of the second sensing area is higher than that of each of the first sensing areas, and is actually higher than that of the plurality of first sensing areas.

It will be appreciated that the second sensing region may also comprise a partial region of the acquisition region. For example, a second sensing array including a plurality of the first sensing arrays may be selected from sensing arrays consisting of m×k sensing units, and the second sensing array may include r×s sensing units.

Alternatively, the second sensing region may be enabled in the event that it is determined that the acquisition region has an operator present. Since the sensing units of the plurality of first sensing regions are already in the enabled state, the sensing units of other regions than the first sensing regions in the second sensing region are actually enabled, so that the sensing units in the whole second sensing region are in the enabled state.

On this basis, a third sensing value of the second sensing region may be obtained at least twice based on the target acquisition period. Optionally, the third sensing value may include a sensing value of a sensing unit in the second sensing region. At this time, the third sensing value may include a sensing value matrix composed of sensing values. Alternatively, the sensing value of the sensing unit in the second sensing area is obtained, and the second processing value may be formed based on the processing of the sensing value of the sensing unit in the second sensing area, and the second processing value may be used as the third sensing value.

Alternatively, based on the acquisition of at least two third sensing values, at least two fingerprint images may be acquired based on the at least two third sensing values, and movement of the operation body with respect to the acquisition region may be determined based on the at least two fingerprint images. For example, a third sensed value for the N-1 th acquisition cycle may be obtained, and the N-1 th fingerprint image may be generated based on the third sensed value for the N-1 th acquisition cycle. After the time period T1, a third sensing value of the nth acquisition period may be acquired, and an nth fingerprint image may be generated based on the third sensing value of the nth acquisition period. Then, a specific point in the N-1 th fingerprint image and a characteristic point in the N-1 th fingerprint image may be identified, and movement of the operator relative to the acquisition region may be determined by comparing the specific point in the N-1 th fingerprint image and the characteristic point in the N-th fingerprint image. In this way, the accuracy of sensing the movement of the operation body with respect to the acquisition region can be improved.

Alternatively, as shown in fig. 4, it may be determined whether or not there is an operation body present based on the first sensing values of the plurality of first sensing regions. If it is determined that the acquisition region has the presence of an operator, a contact event is obtained that characterizes the operator in contact with the acquisition region.

In response to the contact event, a second sensing value may be obtained based on a target acquisition period through a plurality of the first sensing regions. First displacement information for characterizing a movement of the operator relative to the acquisition area may be obtained based on at least two of the sensing values.

In synchronization therewith, a second sensing region of the fingerprint sensor, through which a third sensing value is acquired, may be enabled in response to the contact event. Second displacement information characterizing the movement of the operator relative to the acquisition area may be obtained based on at least two of the third sensing values.

Based on the first displacement information and the second displacement information, consistency of the first displacement information and the second displacement information can be compared, and when the consistency of the first displacement information and the second displacement information meets a target condition, target displacement information can be generated based on the first displacement information and the second displacement information, and the target displacement information is used for identifying movement of an operating body relative to the acquisition area. Control instructions for the electronic device to perform a target operation may be generated based on the target displacement information.

In some embodiments, the processor is specifically configured to:

Alternatively, the processor may trigger a second trigger instruction in response to the target application running. And generating control coordinates corresponding to the movement of the operating body through the second processing mode, and controlling the display content output by the target application program to change through the control coordinates. For example, the processor may trigger a second trigger instruction in response to a camera program start, generate control coordinates corresponding to movement of the operation body through the second processing mode, control a focal length, a focus position, and the like of the camera through the control coordinates. Of course, the control coordinates may also control, for example, the display interface to slide or scroll, etc.

Optionally, the processor may acquire, based on the second trigger instruction, corresponding position information based on at least two third sensing values in the second processing mode, where the position information may be used to characterize a relative position of the operating body and the second sensing area. Control coordinates for controlling a display content change of a screen of the electronic device may be generated based on at least two position information.

Optionally, the processor may also determine, by the second processing mode, a moving direction of the operation body with respect to the acquisition area based on at least two third sensing values, and construct a start coordinate. At least one target coordinate is constructed based on the start coordinate and the direction of movement. For example, a preset reference coordinate may be used as the start coordinate, and a fixed value may be added to form the target coordinate of the subsequent acquisition cycle on the basis of the start coordinate or the target coordinate of the previous acquisition cycle.

It can be understood that, during actual application, the first trigger instruction or the second trigger instruction may be generated for different application scenarios, so as to selectively trigger the first processing mode or the second processing mode. For example, in an application scenario with relatively low control accuracy requirements, a first trigger instruction may be generated to trigger a first processing mode, and control coordinates may be generated based on second sensing values of the plurality of first sensing regions. And generating a second trigger instruction under an application scene with higher control precision requirement, triggering a second processing mode, and generating control coordinates based on a third sensing value of the second sensing region.
