[0023] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The following is combined with Figure 1-7 , the fingerprint calibration method, device and electronic device provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0026] like Figure 1 As shown, an embodiment of the present application provides a fingerprint calibration method, which may include the contents shown in S101 to S102.

[0027] In S101 , when it is detected that the temperature of the electronic device exceeds a temperature threshold, the communication state of the electronic device is detected.

[0028] It is worth noting that the temperature of electronic devices may change during use due to power consumption, environment and other reasons. The temperature has a certain impact on the calibration of fingerprints. Therefore, it is necessary to detect the temperature of the electronic device before fingerprint calibration and determine the calibration process based on the currently measured temperature.

[0029] The temperature detection may be performed in a cycle with a preset time as a monitoring period, or may be performed before calibration, which is not specifically limited in this application.

[0030] In this embodiment, the communication status of the electronic device may include communication status such as talking on the phone and surfing the Internet, and may also include non-communication status such as taking a photo and not in use.

[0031] In S102, a partition calibration is performed on the fingerprint area of ​​the electronic device according to the communication state of the electronic device.

[0032] The fingerprint area includes multiple sub-areas.

[0033] In order to provide a better user experience, this application adopts a large-area under-screen fingerprint. To ensure more accurate calibration of the fingerprint area, the fingerprint area is divided into multiple sub-areas. During fingerprint calibration, multiple sub-areas can be calibrated one by one.

[0034] Here, a plurality refers to two, three or more.

[0035] In this embodiment, it can be determined whether to turn on the calibration or not according to the specific state of the electronic device. If the electronic device is in a non-communication state, the fingerprint area can be calibrated at this time, and the interference signal generated during the calibration will not affect the electronic device; if the frequency band of the electronic device is different from the frequency band of the interference signal generated by the fingerprint calibration, the fingerprint area can also be calibrated at this time, and the interference signal generated during the calibration will not affect the electronic device; if the electronic device is in a communication state, the fingerprint area can be not calibrated. In order to make the determination more accurate, whether to turn on the calibration can be determined based on whether the electronic device is in a communication state.

[0036] In the embodiment of the present application, when it is detected that the temperature of the electronic device exceeds the temperature threshold, the communication state of the electronic device is detected, and the fingerprint area of ​​the electronic device is partitioned and calibrated according to the communication state of the electronic device, wherein the fingerprint area includes multiple sub-areas. By detecting whether the electronic device is in a communication state before calibration, the influence of the interference signal generated by the fingerprint calibration on the radio frequency sensitivity of the electronic device is reduced.

[0037] In a possible embodiment of the present application, Figure 2 As shown, when it is detected that the temperature of the electronic device exceeds the temperature threshold, the communication state of the electronic device is detected, and then whether the electronic device is in the communication state is detected. If it is in the communication state, the fingerprint area is not calibrated; if it is not in the communication state, multiple sub-areas of the fingerprint area are calibrated separately, that is, the first sub-area is calibrated, and then the second sub-area is calibrated, and so on, all sub-areas are calibrated until the calibration is completed.

[0038] This application detects whether the electronic device is in a communication state before calibration. If it is in a communication state, fingerprint calibration is not performed, so as to reduce the impact of interference signals generated by fingerprint calibration on the radio frequency sensitivity of the electronic device and improve the user experience.

[0039] In a possible implementation of the present application, detecting the communication status of the electronic device may include: detecting a frequency band in which the electronic device is located.

[0040] Accordingly, partitioning and calibrating the fingerprint area of ​​the electronic device according to the communication state of the electronic device may include: when the frequency band of the electronic device is not a preset frequency band, or the electronic device is in a non-communication state, calibrating multiple sub-areas of the fingerprint area separately.

[0041] The preset frequency band refers to the frequency band where the interference signal generated by the fingerprint calibration is located, and the non-preset frequency band refers to the frequency band other than the above frequency band.

[0042] In this embodiment, the frequency band of the electronic device can be detected first to determine whether the frequency band is in the same frequency band as the frequency band generated by the fingerprint calibration. If it is not in the same frequency band, the fingerprint calibration can be performed. If it is in the same frequency band, or partially in the same frequency band, the fingerprint calibration cannot be performed. Specifically, when the frequency band of the electronic device is not a preset frequency band or is in a non-communication state, multiple sub-areas of the fingerprint area can be calibrated separately.

[0043] That is to say, fingerprint calibration can be performed when the frequency band of the electronic device is different from the frequency band generated by the fingerprint calibration to ensure that the fingerprint calibration does not affect the communication of the electronic device and improve the user experience.

[0044] In a possible implementation of the present application, partitioning and calibrating the fingerprint area of ​​the electronic device according to the communication status of the electronic device may include: when the electronic device is in a communication state, calibrating multiple sub-areas of the fingerprint area at preset time intervals, wherein the preset time interval is the interval time between calibration of any two sub-areas.

[0045] In this embodiment, if the electronic device is always in a communication state, in order to ensure the accuracy of the fingerprint area, an interval calibration method can be used for calibration. That is, the first sub-area is calibrated first, and then the second sub-area is calibrated after a preset time interval, and then the third sub-area is calibrated after another preset time interval, and so on, until the entire fingerprint area is calibrated. This embodiment reduces the continuous interference to the communication signal of the electronic device and reduces the impact on the radio frequency sensitivity of the electronic device by increasing the calibration time interval between each sub-area.

[0046] It is worth noting that, in this embodiment, calibration can also be performed after a preset time interval between the two sub-areas are calibrated. The one sub-area or two sub-areas mentioned above are one implementation method. That is to say, when the electronic device is in a communication state, the fingerprint area is calibrated. As long as multiple time intervals are set during the calibration process, the impact on the radio frequency sensitivity of the electronic device can be reduced. The specific limitation can be determined according to actual conditions, and the embodiment of the present application does not make specific limitations.

[0047] In a specific embodiment of the present application, Figure 3 As shown, when it is detected that the temperature of the electronic device exceeds the temperature threshold, the communication state of the electronic device is detected. If the electronic device is in a non-communication state, each sub-area is directly calibrated separately until all sub-areas are calibrated; if the electronic device is in a communication state, in order to ensure the accuracy of fingerprint recognition, the first sub-area can be calibrated first. After the calibration of the first sub-area is completed, a preset time is delayed, for example, 2s or 20ms, and then the second sub-area is calibrated, and then a preset time is delayed again, and then the next sub-area is calibrated until all sub-areas are calibrated.

[0048] By calibrating the intervals between the sub-areas, the continuous interference to the communication signals of the electronic equipment can be reduced, and the impact on the radio frequency sensitivity of the electronic equipment can be reduced.

[0049] In a possible implementation of the present application, partitioning and calibrating the fingerprint area of ​​the electronic device according to the communication state of the electronic device may include: when the electronic device is in a non-communication state, calibrating the sub-areas of the fingerprint area in sequence until the electronic device is detected to be in a communication state or the sub-areas of the fingerprint area are detected.

[0050] The sequentially calibrating the sub-regions of the fingerprint region may refer to calibrating the sub-regions of the fingerprint region in a preset order, for example, in an adjacent order, or in any other preset order.

[0051] In an embodiment of the present application, when it is detected that the electronic device is in a non-communication state, a sub-area can be calibrated, and then the communication state of the electronic device can be detected, so as to avoid affecting the radio frequency signal when the user uses the electronic device for communication during the calibration process. When the electronic device is detected to be in a non-communication state again, the second sub-area of ​​the fingerprint area is calibrated, and then the communication state of the electronic device is detected, and so on, until all sub-areas of the fingerprint area are calibrated. By calibrating the sub-areas one by one and detecting the communication state of the electronic device before calibrating each sub-area, the interference signal generated during the calibration process can be minimized to minimize the interference to the communication of the electronic device, thereby improving the user experience.

[0052] In a specific embodiment of the present application, Figure 4As shown, when it is detected that the temperature of the electronic device exceeds the temperature threshold, the communication status of the electronic device is detected. If the electronic device is in the communication state, no calibration is performed. If the electronic device is in the non-communication state, the first sub-area is calibrated, and then the communication status of the electronic device is detected again. If the electronic device is in the communication state, no calibration is performed. If the electronic device is in the non-communication state, the second sub-area is calibrated, and then the communication status of the electronic device is detected again, until all sub-areas are calibrated.

[0053] By calibrating the sub-areas one by one and detecting the communication status of the electronic device before calibrating each sub-area, the interference signal generated during the calibration process on the communication of the electronic device can be minimized, thereby improving the user experience.

[0054] It should be noted that the fingerprint calibration method provided in the embodiment of the present application can be executed by a fingerprint calibration device or a control module in the fingerprint calibration device that executes the fingerprint calibration method. In the embodiment of the present application, the fingerprint calibration device provided in the embodiment of the present application is described by taking the fingerprint calibration method executed by the fingerprint calibration device as an example.

[0055] like Figure 5 As shown, the embodiment of the present application further provides a fingerprint calibration device, which may include: a detection module 501 and a calibration module 502.

[0056] Specifically, the detection module 501 is used to detect the communication status of the electronic device when it is detected that the temperature of the electronic device exceeds the temperature threshold; the calibration module 502 is used to partition and calibrate the fingerprint area of ​​the electronic device according to the communication status of the electronic device, wherein the fingerprint area includes multiple sub-areas.

[0057] In the embodiment of the present application, when it is detected that the temperature of the electronic device exceeds the temperature threshold, the detection module 501 detects the communication state of the electronic device, and according to the communication state of the electronic device, the calibration module 502 performs partition calibration on the fingerprint area of ​​the electronic device, wherein the fingerprint area includes multiple sub-areas. By detecting whether the electronic device is in a communication state before calibration, the influence of the interference signal generated by the fingerprint calibration on the radio frequency sensitivity of the electronic device is reduced.
