The sensor assembly shown in fig. 3 includes two columns of sensor units, and the four sensor units in each dashed box form a sensor set.

In one example, the sensor sets may be arranged in a straight line along a length direction of the side edge of the terminal device (e.g., a longitudinal direction in fig. 1 b) to determine a touch gesture of a user along the side edge direction of the terminal device, and the specific arrangement manner of the sensor sets is not limited by the embodiment of the present application.

In one possible implementation, each sensor unit includes N × N pixel points, where N is a natural number greater than or equal to 8. The pixel point may be a minimum unit of the sensor assembly that outputs the touch signal.

In one possible implementation manner, the fingerprint detection apparatus further includes: and the analog-to-digital converter is used for performing analog-to-digital conversion on the touch signal output by the sensor assembly and outputting the analog-to-digital conversion result to the processing component.

In one possible implementation, the processing component is further configured to: and generating a periodic timing signal, and generating a scanning signal according to the timing signal, wherein the scanning signal is used for sequentially outputting the touch signals output by the sensor units to the input end of the analog-to-digital converter.

For example, the processing component may generate a timing signal every 100 milliseconds, and generate a scanning signal according to the timing signal, where the scanning signal is used to control the sequential gating of the pixels on the fingerprint sensing component. And touch signals generated by all the pixel points are sequentially output to the input end of the analog-to-digital converter.

The touch signal of the sensor component can be detected by a mode of scanning regularly through the timing signal, the device can be prevented from being always in a working state of fingerprint detection, and the power consumption of the device is reduced.

In one possible implementation, the touch signal is an analog voltage signal of a gated pixel. The analog-to-digital converter can discretize analog voltage signals of pixel points in the sensor unit to obtain digital voltage signals of the pixel points. For example, the Analog-to-digital converter may obtain the digital voltage signal of each pixel point by means of ADC (Analog-to-digital converter) sampling.

In one possible implementation, the processing unit is configured to determine the control signal according to each touch signal output by each sensor unit, and includes:

the processing component may generate a vector according to each touch signal output by each sensor unit, where each element in the vector corresponds to a touch result of one sensor set, respectively, and when a control position corresponding to at least one sensor unit in any sensor set is touched, an element value corresponding to the sensor set indicates that the control position corresponding to the sensor set is touched.

The processing means may generate the control signal from a plurality of vectors generated within a preset time period.

For example, each sensor unit includes 8 × 8 pixels, and for each sensor unit, the processing unit determines whether the sensor unit is touched according to the digital voltage signal of each pixel.

For example, a first threshold value is preset in the processing unit, the digital voltage signals of 64 pixels in each sensor unit are accumulated to obtain an accumulated value, if the accumulated value is greater than or equal to the first threshold value, the touch result of the sensor unit is determined to be touched (the corresponding indication signal may be 1), and if the accumulated value is smaller than the first threshold value, the touch result of the sensor unit is determined to be not touched (the corresponding indication signal may be 0).

For example, if the sensor unit of the number 1 in the first sensor set in fig. 3 is touched, it is determined that the sensor set is touched (the corresponding indication signal may be 1); if none of the sensor units numbered 5-8 in the second sensor set in fig. 3 is touched, it is determined that the sensor set is not touched (the corresponding indication signal may be 0); if none of the sensor units numbered 9-12 in the third sensor set in fig. 3 is touched, it is determined that the sensor set is not touched (the corresponding indication signal may be 0).

In a possible implementation manner, the processing component may generate a vector according to the determined touch results of the sensor sets, where each element in the vector corresponds to one sensor set.

For example, in the case where the touch results of the three sensor sets in fig. 3 are 1 (touch result of the third sensor set), 0 (touch result of the second sensor set), and 0 (touch result of the first sensor set), respectively, the processing section generates a vector of [1, 0, 0 ]; in the case where the touch results of the three sensor sets in fig. 3 are 1 (touch result of the third sensor set), 1 (touch result of the second sensor set), and 0 (touch result of the first sensor set), respectively, a vector of [1, 1, 0] is generated.

In a possible implementation, the processing unit is configured to generate the control signal according to a plurality of vectors generated within a preset time period.

For example, the processing component may generate a vector after the scanning signal sequentially outputs the touch signals of all the pixels of the sensor component to the input end of the analog-to-digital converter each time, and when the vectors generated within the preset time period are [0, 0, 0], [1, 0, 0], [1, 1, 0], [1, 1, 1], [0, 1, 1], [0, 0, 1], [0, 0, 0] sequentially in time sequence (corresponding to a decimal signal variation trend of the vector: 0- >4- >6- >7- >3- >1- >0), the processing component determines that the touch gesture slides on the control along the first direction to generate the control signal corresponding to the touch gesture; if the vectors generated in the preset time period are [0, 0, 0], [0, 0, 1], [0, 1, 1], [1, 1, 1], [1, 1, 0], [1, 0, 0], [0, 0, 0] (decimal signal variation trend corresponding to the vectors: 0- >1- >3- >7- >6- >4- >0) in sequence in time, the processing unit determines that the touch gesture is sliding on the control in the second direction and generates the control signal corresponding to the touch gesture.

The control signal is generated according to a plurality of vectors generated within a preset time period (the control signal corresponds to a touch gesture). Compared with the mode that the terminal equipment acquires the touch gesture according to the displacement of the fingerprint characteristic points on the fingerprint image by regularly acquiring two frames of fingerprint images in the related art, the fingerprint detection and parameter adjusting device in the disclosure has the advantages of low algorithm complexity and lower power consumption for determining the touch gesture on the sensor assembly.

In one possible implementation, the processing component is configured to: and when the preset time period is determined to be reached according to the timing signal, determining the control signal according to the touch signal obtained in the preset time period. For example, the timing signal may be generated once every 100 milliseconds, and if there are M pixels in the sensor component, the time required for scanning all the pixels is 100ms × M, that is, the time required for obtaining one vector, and if at least 7 vectors need to be obtained to determine the gesture, the preset time period may be set to be 7 × 100ms × M or more. And the processing part determines the control signal according to the pixel point touch signal of the sensor obtained in the preset time period.

In one possible implementation manner, the control signal is used for adjusting the volume of the terminal device. For example, the control signal may be used to increase the volume when the control signal corresponds to a touch gesture of sliding over the control in a first direction, and may be used to decrease the volume when the control signal corresponds to a touch gesture of sliding over the control in a second direction. The first direction may be a downward sliding in fig. 1b, and the second direction may be a downward sliding in fig. 1 b. Alternatively, the first direction may be from top to bottom in fig. 1b, and the second direction may be from bottom to top in fig. 1 b.

In a possible implementation manner, a first General-purpose input/output GPIO port (General-purpose input/output) and the second General-purpose input/output GPIO port may be added to the fingerprint chip. When the control signal corresponds to the touch gesture and slides on the control in the first direction, the control signal can control the level of the first general input/output GPIO port to be increased, so that the volume is increased; when the control signal corresponds to the touch gesture and slides on the control in the second direction, the control signal can control the level of the second general input/output GPIO port to be increased, and therefore the volume is reduced.

In one possible implementation, the control signal is also used to perform a function in an application program.

For example, the processing component may output the control signal to an upper layer application program through a protocol (e.g., One Wire single bus protocol) so that the application program implements One or more functions of the application program according to the control signal. For example, the application may be audio-visual software, social software, electronic book software, application marketplace software, or browser software.

For example, different interfaces of the social software are switched according to the control signals corresponding to the touch gestures; or turning pages of the electronic book according to the control signal corresponding to the touch gesture; or, the webpage scrolling of the browser software is realized according to the control signal corresponding to the touch gesture. Or, the up-and-down scrolling of the application list is realized according to the control signal corresponding to the touch gesture.

In a possible implementation manner, the terminal device may determine the control signal for adjusting the operating parameter of the terminal device or for executing the function of the application program according to the state of the current application program. For example, if the application is not turned on, the control signal may be used to adjust an operating parameter of the terminal device, such as adjusting the volume. If the application program is started and in an audio or video playing state, the control signal can be used for adjusting the operating parameters of the terminal equipment, such as adjusting the volume. If the application is opened and not in an audio or video playing state, such as a text presentation or a web page presentation, the control signal may be used to perform a function of the application, such as turning a page or the like. The specific function of the control signal can be preset according to the requirement.

The terminal equipment comprises the fingerprint detection and parameter adjustment device. In a possible implementation manner, the control in the fingerprint detection apparatus is disposed in a middle frame of the terminal device.

The method can be applied to terminal equipment with a fingerprint detection function, for example, the method can be applied to a fingerprint detection and parameter adjustment device shown in fig. 2 and executed by a processing component.
