[0001] The present application belongs to the field of communication technology, and specifically relates to a fingerprint recognition method, device and electronic equipment. Background Art

[0002] With the development of fingerprint recognition technology, in-display fingerprint recognition has become an important basic function of smartphones and a focus of consumer attention. When the fingerprint module recognizes a fingerprint, it needs a light-emitting element to illuminate the fingerprint recognition area, making the fingerprint recognition area brighter and thus identifying the fingerprint located in the fingerprint recognition area.

[0003] In related technologies, when an electronic device receives information or is in a specific posture, a light-emitting element illuminates the fingerprint recognition area, highlighting the fingerprint recognition area and prompting the fingerprint unlocking operation. However, in some application environments, such as in low light conditions, directly highlighting the fingerprint recognition area can cause problems such as glare and power consumption. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a fingerprint recognition method, device and electronic device, which can solve the problems of glare or power consumption caused by directly highlighting the fingerprint recognition area.

[0005] In a first aspect, embodiments of the present application provide a fingerprint recognition method, which is applied to an electronic device. The electronic device includes a display screen and a fingerprint module. The display screen includes a fingerprint recognition area. The fingerprint module is disposed within the electronic device and opposite to the fingerprint recognition area. The fingerprint module includes a light-emitting element. The fingerprint recognition method includes:

[0006] receiving a first input from a user in a fingerprint recognition area;

[0007] In response to the first input, the light emitting element is controlled to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful.

[0008] In a second aspect, an embodiment of the present application provides a fingerprint recognition device, which includes:

[0009] A receiving module, configured to receive a first input from a user in a fingerprint recognition area;

[0010] The control module is used to control the light-emitting element to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful.

[0011] In a third aspect, an embodiment of the present application provides an electronic device comprising a processor, a memory, and a program or instruction stored in the memory and executable on the processor, wherein the program or instruction, when executed by the processor, implements the steps of the method described in the first aspect.

[0012] In a fourth aspect, an embodiment of the present application provides a readable storage medium, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

[0014] Through the technical solution disclosed in the embodiments of the present application, when a first input from a user in the fingerprint recognition area is received, the light-emitting element can be controlled to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful. This can prevent at least a portion of the fingerprint recognition area from directly entering a high-brightness state and irritating the human eye in some special application scenarios, such as in a dark light state. Since at least a portion of the fingerprint recognition area gradually brightens from the first brightness, it does not necessarily need to be brightened to an extreme state when the fingerprint recognition is successful. Therefore, compared with the case where at least a portion of the fingerprint recognition area directly brightens to an extreme state, power consumption can be reduced.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0025] The present application embodiment provides a fingerprint recognition method. Figures 1 to 8 , the fingerprint recognition method provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0026] The electronic device disclosed in this application includes a display screen and a fingerprint module. The display screen includes a fingerprint recognition area. The fingerprint recognition module is disposed within the electronic device and opposite the fingerprint recognition area. The fingerprint module includes a light-emitting element that can emit light and illuminate the fingerprint recognition area, thereby brightening the fingerprint recognition area. The fingerprint module can illuminate the fingerprint recognition area through the light-emitting element to identify a fingerprint located in the fingerprint recognition area.

[0027] Figure 1 The flowchart of the first fingerprint recognition method provided by the embodiment of the present application is shown. The method can be executed by an electronic device, such as a terminal device. That is, the fingerprint recognition method can be executed by hardware or software installed in the terminal device. Figure 1 As shown, the fingerprint recognition method includes the following steps:

[0028] S101: Receive a first input from a user in a fingerprint recognition area.

[0029] Specifically, the first input can be a finger pressing the fingerprint recognition area, or the first input can be a finger placed above the fingerprint recognition area without touching the fingerprint recognition area. The first input is required to unlock the electronic device when the electronic device receives a message or is in a preset posture.

[0030] S102: In response to the first input, control the light-emitting element to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful.

[0031] Specifically, the light-emitting element may illuminate the entire fingerprint recognition area or a portion of the fingerprint recognition area. When gradually brightening at least a portion of the fingerprint recognition area from a preset first brightness, the power of the light-emitting element may be controlled or the number of light-emitting units of the light-emitting element may be controlled to gradually brighten at least a portion of the fingerprint recognition area from the first brightness.

[0032] The first brightness can be a preset brightness level. The first brightness can be the brightness that is more comfortable for the human eye when the light generated by the fingerprint recognition area or the screen is in a dark light state, or the brightness that is more comfortable for the human eye when it is suddenly exposed to light in a dark light state. The first brightness can be obtained through experiments and then preset to the electronic device. The brightness can be divided into levels, and different brightnesses correspond to different levels. For example, the brightness is 0 in a dark light state, and the brightness can be divided into different levels such as 0, 1, 2, and 3 in the process of gradually brightening from the dark light state. The larger the number, the higher the brightness level, and the higher the brightness. At least a part of the fingerprint recognition area gradually brightens from the preset first brightness, which can be a change from a low level brightness to a high level brightness, changing one level each time. The first brightness can be the brightness in a dark light state, that is, the brightness level is 0 (that is, the brightness is 0). Of course, the first brightness can also be other brightness levels.

[0033] In the process of gradually brightening at least a part of the fingerprint recognition area from the preset first brightness, it is also necessary to set the extreme state of the brightness when the brightness gradually brightens. The brightness corresponding to the state in which the first brightness gradually brightens to the extreme value is the high-brightness state. There can be multiple different brightness levels between the first brightness and the high-brightness state. In the process of gradually brightening the first brightness, the brightness level is gradually increased starting from the first brightness until the fingerprint recognition is successful. Optionally, if the fingerprint module still cannot recognize the fingerprint in the high-brightness state, the light-emitting element illuminates at least a part of the fingerprint recognition area so that at least a part of the fingerprint recognition area gradually brightens from the first brightness again until the fingerprint recognition is successful. In the process of gradually brightening at least a part of the fingerprint recognition area from the first brightness, as long as the brightness of at least a part of the fingerprint recognition area can make the fingerprint recognition successful, it directly enters the unlocked state after fingerprint recognition.

[0034] Through the technical solution disclosed in the embodiments of the present application, when a first input from a user in the fingerprint recognition area is received, the light-emitting element can be controlled to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful. This can prevent at least a portion of the fingerprint recognition area from directly entering a high-brightness state and irritating the human eye in some special application scenarios, such as in a dark light state. Since at least a portion of the fingerprint recognition area gradually brightens from the first brightness, it does not necessarily need to be brightened to an extreme state when the fingerprint recognition is successful. Therefore, compared with the case where at least a portion of the fingerprint recognition area directly brightens to an extreme state, power consumption can be reduced.

[0035] like Figure 7 It is shown that when a pressing operation of a finger pressing the fingerprint recognition area is received, the light-emitting element illuminates at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness, and the fingerprint module recognizes the fingerprint until the fingerprint recognition is successful.

[0036] In one possible implementation, the first input is a pressing operation of the fingerprint recognition area. In response to the first input, controlling the light-emitting element to illuminate at least a portion of the fingerprint recognition area so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness includes: in response to the first input, controlling the light-emitting element to illuminate at least a portion of the fingerprint recognition area based on a duration of the pressing operation so that at least a portion of the fingerprint recognition area gradually brightens from the first brightness to a target brightness, where the target brightness is positively correlated with the pressing time.

[0037] Specifically, the first input may be a pressing operation of a finger on the fingerprint recognition area. The target brightness is proportional to the duration of the pressing operation. As the duration of the pressing operation increases, the corresponding target brightness becomes brighter. For example, the brightness corresponding to a pressing operation duration of 2 seconds is brighter than the brightness corresponding to a pressing operation duration of 1 second. When at least part of the fingerprint recognition area gradually changes to an extreme value, the target brightness is no longer proportional to the duration of the pressing operation. The target brightness will no longer continue to increase. The target brightness and duration may have a one-to-one correspondence and may be preset in the electronic device.

[0038] After the first input is detected, at least a portion of the fingerprint recognition area may begin to gradually brighten with the pressing time, or may begin to gradually brighten after a delay period after the first input.

[0039] Through the technical solution disclosed in the embodiments of the present application, the first input is limited to a pressing operation on the fingerprint recognition area, so that according to the duration of the pressing operation, at least a part of the fingerprint recognition area can be controlled to gradually brighten from the first brightness to the target brightness, so that the brightness of at least a part of the fingerprint recognition area changes stably with the duration of the pressing operation.

[0040] In one possible implementation, the first input is a pressing operation of pressing the fingerprint recognition area. In response to the first input, controlling the light-emitting element to illuminate at least a portion of the fingerprint recognition area so that the at least portion of the fingerprint recognition area gradually brightens from a preset first brightness includes: determining an overlapping area where the pressing area corresponding to the pressing operation overlaps with the fingerprint recognition area, and in response to the first input, controlling the light-emitting element to illuminate the overlapping area so that the overlapping area gradually brightens from the first brightness.

[0041] Specifically, the first input may be a pressing operation of a finger pressing the fingerprint recognition area. The pressing area corresponding to the pressing operation may be entirely located in the fingerprint recognition area, partially located in the fingerprint recognition area, or entirely outside the fingerprint recognition area. When the pressing area is entirely or at least partially located in the fingerprint recognition area, the pressing area and the fingerprint recognition area have an overlapping area.

[0042] The detection method of the overlapping area can adopt the existing detection method. For example, a plurality of touch detection pins can be evenly arranged below the fingerprint recognition area. Each touch detection pin can correspond to a fixed local area of the fingerprint recognition area. In the actual operation process, when the first input is received, the pressing operation will trigger the touch detection pin located in the overlapping area, and the overlapping area is determined based on the triggered touch detection pin. The overlapping area can also be detected by an infrared detection device, which will not be described here. Figure 8It is shown that when a finger presses the fingerprint recognition area, the light emitting element illuminates the overlapping area so that the overlapping area gradually brightens from the first brightness until the fingerprint recognition is successful.

[0043] Through the technical solution disclosed in the embodiments of the present application, by further determining the overlapping area between the pressing area and the fingerprint recognition area, when performing fingerprint unlocking, only the overlapping area is illuminated by the light-emitting element, so that the overlapping area gradually brightens from a first brightness, thereby improving the effective illumination of the light-emitting element and avoiding excessive ineffective illumination of the light-emitting element and power loss. By gradually brightening the brightness of the overlapping area, the light in the overlapping area will be blocked by the pressing operation actuator, so that the light in the fingerprint recognition area will not enter the human eye and cause eye discomfort. This is particularly beneficial at night, as it can prevent bright light from entering the human eye and causing eye discomfort.

[0044] In one possible implementation, in response to a first input, controlling the light-emitting element to illuminate at least a portion of the fingerprint recognition area so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness, further comprising: detecting the actual area of the overlapping area; controlling the light-emitting element to illuminate the overlapping area so that the overlapping area gradually brightens from the first brightness, including: when the actual area is greater than a preset threshold, controlling the light-emitting element to illuminate the overlapping area so that the overlapping area gradually brightens from the first brightness, wherein the preset threshold is the minimum pressing area that allows successful fingerprint recognition.

[0045] Specifically, the actual area of the overlapping region can be detected using existing detection methods. For example, when detecting the overlapping region, touch detection pins can be used, and the actual area of the overlapping region can be calculated based on the number of triggered touch detection pins. When detecting the overlapping region using an infrared detection device, detection can be performed based on the received reflected infrared light. The preset threshold is the minimum pressure area preset by the system for successful fingerprint recognition. The preset threshold can be determined through experimentation.

[0046] Through the technical solution disclosed in the embodiments of the present application, it is possible to further detect the actual area of the overlapping area, so that when the actual area is greater than a preset threshold, the light-emitting element is controlled to illuminate the overlapping area, so that the overlapping area gradually brightens from the first brightness. This can avoid the situation where the fingerprint cannot be successfully recognized or the recognition success rate is low due to the actual area being too small, and the overlapping area is further gradually brightened from the first brightness. This can further avoid the ineffective brightening of the overlapping area and the loss of power, and in some cases, the waste of unlocking opportunities of electronic devices due to fingerprint recognition failure.

[0047] In a possible implementation, the fingerprint recognition method further includes: when the actual area is smaller than a preset threshold, the light-emitting element illuminates the overlapping area so that the overlapping area is maintained at a first brightness, and issues a prompt message prompting the user to press again.

[0048] Through the above embodiment, when the actual area of the overlapping area is smaller than the preset threshold, the brightness of the overlapping area is maintained at the first brightness, and a prompt message is issued to prompt the user to press again, thereby avoiding the overlapping area continuing to gradually brighten and waste power when the actual area is not enough to successfully unlock. The user can also be prompted in time to press again, thereby further improving the user experience.

[0049] In dim light, the human eye perceives sudden changes in light as glare, but will gradually adapt to gradually brighter light without any noticeable glare.

[0050] Figure 2 The flowchart of the second fingerprint recognition method provided by the embodiment of the present application is shown. The method can be executed by an electronic device, such as a terminal device. That is, the fingerprint recognition method can be executed by hardware or software installed in the terminal device. Figure 2 As shown, the method includes the following steps:

[0051] S200: Obtaining environmental status.

[0052] Environmental conditions may include dark and bright light conditions. These conditions may be pre-defined and detected by a photosensor. The photosensor determines the environmental condition by detecting light intensity. When detecting dark and bright light conditions, the photosensor may have preset light intensity values. When the light intensity value exceeds the preset value, the condition is determined to be bright light. When the light intensity is less than or equal to the preset value, the condition is determined to be dark light. A dark light condition may be an environmental condition that causes glare and discomfort to the human eye when suddenly exposed to high-brightness light. A bright light condition may be an environmental condition that causes no glare to the human eye when suddenly exposed to high-brightness light.

[0053] S201: When the environment is in a dark light state, receiving a first input from a user in a fingerprint recognition area.

[0054] Receiving a first input from a user on the fingerprint recognition area is specifically: receiving a first input from a user on the fingerprint recognition area when the ambient light state is low. The first input may be a pressing operation of a finger on the fingerprint recognition area.

[0055] By judging the environmental state, the acceptance of the user's first operation in the fingerprint recognition area is limited to the dark light state, so that in the dark light state, at least a part of the fingerprint recognition area gradually brightens from the first brightness to adapt to the human eye's ability to receive light, thereby avoiding the problem of at least a part of the fingerprint recognition area being directly highlighted in the dark light state and causing discomfort to the human eye.

[0056] S202: In response to the first input, control the light-emitting element to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful.

[0057] S203: When the ambient light state is bright, receiving a second input from the user in the fingerprint recognition area;

[0058] S204: In response to the second input, control the light-emitting element to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area directly enters a highlighted state.

[0059] The highlight state is a state in which the light emitting element illuminates at least a portion of the fingerprint recognition area so that at least a portion of the fingerprint recognition area maintains a preset brightness value.

[0060] Specifically, the preset brightness value is the brightness of at least a portion of the fingerprint recognition area under bright light conditions that satisfies the requirement for rapid and accurate fingerprint recognition. The preset brightness value can be obtained through experimentation and preset in the electronic device. The preset brightness value can also be the brightness value corresponding to a state in which at least a portion of the fingerprint recognition area gradually brightens from a first brightness to an extreme brightness.

[0061] Through the technical solution disclosed in the embodiments of the present application, in a dim light state, a first input from the user is received, and in response to the first input, the light-emitting element illuminates at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful; and in a bright light state, a second input from the user is received, and in response to the second input, the light-emitting element is controlled to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area directly enters a high-brightness state. Since the human eye has a weak ability to receive light in a dim light state, controlling at least a portion of the fingerprint recognition area to gradually brighten from the first brightness can adapt to the human eye's adaptation process to light, thereby preventing high-brightness light from directly entering the human eye. Since the human eye has a strong ability to receive light in a bright light state, controlling at least a portion of the fingerprint recognition area to directly enter a high-brightness state will not cause discomfort to the human eye, and can improve the success rate of fingerprint recognition and the recognition rate during fingerprint recognition, thereby improving the user's overall experience of the electronic device.

[0062] S200 may be executed before S201 and S203, or S200, S201, and S203 may be executed simultaneously.

[0063] It is worth noting that S201 has the same or similar implementation method as the above-mentioned S101, and they can refer to each other, and the embodiments of the present application will not be repeated here.

[0064] Figure 3 The flowchart of the third fingerprint recognition method provided by the embodiment of the present application is shown. The method can be executed by an electronic device, such as a terminal device. That is, the fingerprint recognition method can be executed by hardware or software installed in the terminal device. Figure 3 As shown, the method includes the following steps:

[0065] S300: Obtaining environmental status.

[0066] Environmental conditions may include dark and bright light conditions. These conditions may be pre-classified and detected by a photosensor. The light intensity detected by the photosensor is used to determine the environmental condition. When the photosensor detects dark and bright light conditions, a light intensity value may be preset. A light intensity value greater than the preset value may be considered a bright light condition, while a light intensity value less than or equal to the preset value may be considered a dark light condition. A dark light condition may be an environmental condition where the human eye is glaring and uncomfortable when suddenly exposed to high-brightness light. A bright light condition may be an environmental condition where the human eye is not glaring when suddenly exposed to high-brightness light.

[0067] The first input is a pressing operation of pressing the fingerprint recognition area.

[0068] Receive the user's first input in the fingerprint recognition area, specifically:

[0069] S301: When the environment is in a dim light state, receiving a first input from a user in a fingerprint recognition area.

[0070] In response to the first input, controlling the light-emitting element to illuminate at least a portion of the fingerprint recognition area so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful includes:

[0071] S302: In response to the first input, determine the overlapping area where the pressing area corresponding to the pressing operation overlaps with the fingerprint recognition area, and control the light-emitting element to illuminate the overlapping area based on the duration of the pressing operation, so that the overlapping area gradually brightens from the first brightness to the target brightness, and the target brightness is positively correlated with the duration of the pressing operation.

[0072] Specifically, the first input may be a pressing operation of a finger pressing the fingerprint recognition area. The pressing area corresponding to the pressing operation may be entirely located in the fingerprint recognition area, partially located in the fingerprint recognition area, or entirely outside the fingerprint recognition area. When the pressing area is entirely or at least partially located in the fingerprint recognition area, the pressing area and the fingerprint recognition area have an overlapping area.

[0073] The overlapping area can be detected using existing detection methods. For example, multiple touch detection pins can be evenly distributed below the fingerprint recognition area, with each touch detection pin corresponding to a fixed local area of the fingerprint recognition area. During actual operation, when a first input is received, a press operation will trigger the touch detection pins located in the overlapping area, and the overlapping area is determined based on the triggered touch detection pins. The overlapping area can also be detected using an infrared detection device, which will not be detailed here.

[0074] The target brightness is proportional to the duration of the pressing operation. As the duration of the pressing operation increases, the corresponding target brightness becomes brighter. For example, the brightness corresponding to a pressing operation duration of 2 seconds is brighter than the brightness corresponding to a pressing operation duration of 1 second. When at least part of the fingerprint recognition area gradually changes to an extreme value state, the target brightness is no longer proportional to the duration of the pressing operation. The target brightness will no longer continue to increase. The target brightness and duration can have a one-to-one correspondence and can be preset in the electronic device. After detecting the first input, at least part of the fingerprint recognition area can start to gradually brighten synchronously with the pressing time, or can start to gradually brighten after a delay period after the first input.

[0075] Fingerprint recognition methods also include:

[0076] S303: When the environment state is the bright light state, receiving a second input from the user in the fingerprint recognition area.

[0077] S304: In response to the second input, control the light-emitting element to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area directly enters a highlighted state.

[0078] The highlighted state is a state where the light-emitting element illuminates at least a portion of the fingerprint recognition area, maintaining a preset brightness value. Specifically, the preset brightness value is a brightness that satisfies the requirement for rapid and accurate fingerprint recognition in a bright light environment. The preset brightness value can be obtained experimentally and preset in the electronic device. The preset brightness value can also be a state corresponding to at least a portion of the fingerprint recognition area gradually brightening from a first brightness to an extreme brightness.

[0079] According to the technical solution disclosed in the embodiment of the present application, when the environment is in a dim light state, a first input from the user is received, and in response to the first input, the light-emitting element is controlled to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful. When the environment is in a bright light state, a second input from the user is received in the fingerprint recognition area, and in response to the second input, the light-emitting element is controlled to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area directly enters a high-brightness state. Since the human eye has a weak ability to receive light in a dim light state, controlling the overlapping area to gradually brighten from a first brightness can adapt to the human eye's adaptation process to light, thereby preventing high-brightness light from directly entering the human eye. By controlling the light-emitting element to illuminate the overlapping area so that the overlapping area gradually brightens from a first brightness, the effective illumination of the light-emitting element can be increased, thereby avoiding excessive ineffective illumination of the light-emitting element and power loss. By gradually brightening the brightness of the overlapping area, the light in the overlapping area will be blocked by the pressing operation actuator, so that the light in the fingerprint recognition area will not enter the human eye and cause eye discomfort. This is particularly beneficial in night conditions, as it can prevent bright light from entering the human eye and causing eye discomfort. In bright light conditions, the human eye has a stronger ability to receive light. Controlling at least part of the fingerprint recognition area to directly enter a high-brightness state will not cause discomfort to the human eye, but can also increase the success rate of fingerprint recognition and the recognition rate during fingerprint recognition, thereby improving the user experience of electronic devices as a whole.

[0080] It should be noted that the fingerprint recognition method provided in the embodiments of the present application can be executed by a fingerprint recognition device or a control module in the fingerprint recognition device for executing the fingerprint recognition method. In the embodiments of the present application, the fingerprint recognition device provided in the embodiments of the present application is described by taking the fingerprint recognition method executed by the fingerprint recognition device as an example.

[0081] Figure 4 A schematic structural diagram of a fingerprint recognition device provided in an embodiment of the present application is shown. The fingerprint recognition device is applied to an electronic device. The electronic device includes a display screen and a fingerprint module. The display screen includes a fingerprint recognition area. The fingerprint module is arranged inside the electronic device and opposite to the fingerprint recognition area. The fingerprint module includes a light-emitting element. The fingerprint recognition device includes: a receiving module 401 for receiving a first input from a user in the fingerprint recognition area.

[0082] The control module 402 is configured to control the light emitting element to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful.

[0083] A fingerprint recognition device disclosed in an embodiment of the present application receives a first input from a user in a fingerprint recognition area through a receiving module 401, and controls a light-emitting element through a control module 402 to illuminate at least a portion of the fingerprint recognition area, so that at least a portion of the fingerprint recognition area gradually brightens from a preset first brightness until the fingerprint recognition is successful. In this way, in some special application scenarios, such as in a dark light state, it is possible to avoid directly highlighting at least a portion of the fingerprint recognition area, which would cause discomfort to the human eye, thereby improving the user experience.

[0084] In a possible implementation, the method further includes: an acquisition module configured to acquire an environmental state.

[0085] The acquisition module may include a photosensor, which detects the intensity of light through the photosensor, and then determines whether the environmental state is a dark light state or a bright light state according to preset judgment conditions.

[0086] The receiving module 401 is configured to receive a first input from a user in a fingerprint recognition area when the environment is in a dim light state.

[0087] The acquisition module can acquire the environmental status at the same time as the receiving module 401 receives the first input, or before the receiving module 401 receives the first input. The acquisition module is always in the detection state, and the environmental status detected by the acquisition module can also be used for other functional modules.

[0088] In a possible implementation, the receiving module 401 is further configured to receive a second input from the user in the fingerprint recognition area when the ambient state is a bright light state.

[0089] The control module 402 is further configured to, in response to a second input, control the light emitting element to illuminate at least a portion of the fingerprint recognition area when the ambient light state is bright, so that at least a portion of the fingerprint recognition area directly enters a high-light state.

[0090] In a possible implementation, the first input is a pressing operation of pressing the fingerprint recognition area.
