[0049] An embodiment of the first aspect of this application provides an electronic device 100, such as... Figures 1 to 3As shown, the electronic device 100 includes a frame assembly 110, a screen 120, a camera assembly 130, and a fingerprint recognition module 140.

[0050] In the electronic device 100 provided in this application embodiment, the electronic device 100 includes a frame assembly 110, a screen 120, a camera assembly 130, and a fingerprint recognition module 140. The frame assembly 110 includes a wall panel 111 and a cavity 112 enclosed by the wall panel 111 and opening in a first direction X. The screen 120 is connected to the wall panel 111 and covers the opening. The components of the electronic device 100 can be accommodated in the cavity 112. The wall panel 111 is provided with a first mounting hole 113. The camera assembly 130 is disposed in the cavity 112. The camera assembly 130 is positioned facing the first mounting hole 113 to allow external light to enter and form an image. The fingerprint recognition module 140 includes a sensing mechanism 150, a collection mechanism 160, and a recognition mechanism 170. The sensing mechanism 150 and the collection mechanism 160 are electrically connected. The sensing mechanism 150 can sense finger pressure, the collection mechanism 160 can collect actual fingerprint information and transmit it to the recognition mechanism 170, and the recognition mechanism 170 can compare and analyze the actual fingerprint information with pre-stored fingerprint information. The fingerprint recognition process is completed. The acquisition mechanism 160 includes a capacitive touchpad 151, which is connected to and covers the mounting hole of the wall panel 111. The capacitive touchpad 151 is independent of the frame assembly 110 and the screen 120, with a clearly defined structure for easy blind fingerprint recognition. The light transmittance of the capacitive touchpad 151 is greater than or equal to a preset light transmittance, allowing external light to enter the camera assembly 130 through the capacitive touchpad 151. The camera assembly 130 is located on the side of the capacitive touchpad 151 facing the screen 120. The capacitive touchpad 151 serves to protect the camera component 130. The capacitive touchpad 151 integrates the function of a protective cover for the camera component 130, which helps to improve the integration of the electronic device 100 and eliminates the need for additional holes in the frame component 110, thus improving the integrity of the electronic device 100. The capacitive touchpad 151 can sense finger pressure to activate the collection mechanism 160. The capacitive touchpad 151, located on the outside of the electronic device 100, facilitates direct contact with the user's finger, which helps to improve the sensitivity of fingerprint recognition.

[0051] The electronic device 100 in this application embodiment may be a mobile phone, a personal digital assistant (PDA), a tablet computer, an e-reader, a television, an access control system, a smart landline phone, a control console, etc.

[0052] Optionally, the frame assembly 110 includes a split-formed middle frame and a back panel. The middle frame is typically made of metal (such as aluminum alloy, titanium alloy, etc.) or plastic, serving as the supporting "skeleton" for internal components (such as camera assembly 130, audio assembly, etc.). The back panel and screen 120 are respectively connected to the middle frame on both sides in the first direction X. The back panel and screen 120 are connected to the middle frame by means of clips, adhesives, or screws. The first mounting hole 113 is provided through the back panel; or the middle frame and the back panel are integrally formed, and the first mounting hole 113 and the screen 120 are arranged opposite each other along the first direction X.

[0053] Optionally, the size and shape of the first mounting hole 113 can be designed independently. For example, the first mounting hole 113 may be a circular hole or a rectangular hole, etc.

[0054] Optionally, the camera assembly 130 is connected to the mid-frame, and the lens of the camera assembly 130 is positioned facing the first mounting hole 113, so that external light can enter the camera assembly 130 through the first mounting hole 113.

[0055] The fingerprint recognition module 140 includes a sensing mechanism 150, a collection mechanism 160, and a recognition mechanism 170. The sensing mechanism 150 senses finger pressure to activate the collection mechanism 160. That is, when the user places their finger on the sensing mechanism 150, the sensing mechanism 150 emits a signal to the collection mechanism 160, which collects the actual fingerprint information. The collection mechanism 160 then sends the collected fingerprint information to the recognition mechanism 170. The recognition mechanism 170 stores at least one pre-stored fingerprint information. The recognition mechanism 170 compares and analyzes the actual fingerprint information and at least one pre-stored fingerprint information. If the similarity between the actual fingerprint information and a pre-stored fingerprint information is greater than or equal to a threshold, the actual fingerprint information and the pre-stored fingerprint information are determined to be the same. If the similarity between the actual fingerprint information and a pre-stored fingerprint information is less than the threshold, the actual fingerprint information and the pre-stored fingerprint information are determined to be different, thereby realizing the fingerprint recognition process. Afterward, the corresponding result information is sent to the central processing unit.

[0056] Optionally, the acquisition mechanism 160 is connected to the sensing mechanism 150 via a transparent wire. For example, the transparent wire may be an indium tin oxide wire.

[0057] The acquisition mechanism 160 includes a capacitive touch panel 151. The light transmittance of the capacitive touch panel 151 is greater than or equal to a preset light transmittance, making it a transparent material with sufficient light transmittance to allow external light to enter the camera assembly 130. Thus, when the capacitive touch panel 151 acts as a protective cover for the camera assembly 130 and closes to the first mounting hole 113, its impact on the performance of the camera assembly 130 is minimal.

[0058] The capacitive touchpad 151 senses user operations by detecting changes in capacitance. When a user presses the capacitive touchpad 151 with their finger, the change in capacitance activates the fingerprint sensor 160. Using the capacitive touchpad 151 also helps to distinguish whether a finger is pressing the fingerprint recognition module 140, thus mitigating the problem of false activation of the fingerprint sensor 160 and its impact on device battery life.

[0059] Optionally, the capacitive touchpad 151 can integrate the function of the acquisition mechanism 160. The capacitive touchpad 151 includes an electrode plate that integrates multiple semiconductor sub-sensors. When a finger presses the capacitive touchpad 151, a micro-electric field is formed between the finger and the capacitive touchpad 151. According to the height and pattern of the fingerprint, the capacitance value between the finger and the electrode plate also changes. This changing capacitance value forms the actual fingerprint information and is transmitted to the recognition mechanism 170.

[0060] Optionally, the acquisition mechanism 160 can be a camera component 130 or a photosensitive sensor, etc.

[0061] Optionally, the identification mechanism 170 can be the central processing unit of the device.

[0062] Optionally, the capacitive touch panel 151 covers the first mounting hole 113, and the capacitive touch panel 151 serves to protect the camera assembly 130 from dust.

[0063] Optionally, the capacitive touchpad 151 is connected to the wall panel 111 by adhesive and / or snap-fit ​​to improve the connection reliability between the capacitive touchpad 151 and the wall panel 111.

[0064] For example, the capacitive touchpad 151 can be attached to either side of the back panel in its thickness direction.

[0065] Optionally, considering that the capacitive touchpad 151 and the wall panel 111 are set independently, and that the capacitive touchpad 151 and the wall panel 111 are made of different materials and have different tactile sensations, users can identify the capacitive touchpad 151 by touch without looking at the fingerprint recognition module 140, so as to facilitate blind fingerprint recognition.

[0066] Optionally, the fingerprint recognition module 140 and the camera assembly 130 share the same first mounting hole 113, which helps to reduce the number of openings on the frame assembly 110 and improve the integrity of the frame assembly 110.

[0067] Optionally, compared to fingerprint recognition solutions located on side buttons, the capacitive touchpad 151 covering the first mounting hole 113 has a larger area, which helps to improve the recognition rate.

[0068] In some embodiments, such as Figures 1 to 3As shown, the acquisition mechanism 160 includes a light source 161 and an acquisition unit 162 that are electrically connected to each other. The light source 161 is electrically connected to the capacitive touch panel 151, and the acquisition unit 162 is electrically connected to the recognition mechanism 170. The fingerprint recognition module 140 is configured such that when a finger presses the capacitive touch panel 151, the light source 161 emits light to the capacitive touch panel 151, and the acquisition unit 162 receives the light reflected and / or refracted by the finger to generate actual fingerprint information.

[0069] In these embodiments, when a finger presses the capacitive touchpad 151, the light source 161 emits light to the capacitive touchpad 151, and the acquisition unit 162 receives the light reflected and / or refracted by the finger to generate actual fingerprint information. The reliability of fingerprint acquisition is improved through the cooperation of the acquisition unit 162 and the capacitive touchpad 151.

[0070] Specifically, when a finger presses the capacitive touchpad 151, the capacitance value of the capacitive touchpad 151 changes to activate the light source 161. The light from the light source 161 illuminates the cover plate and is reflected and / or refracted at the fingerprint area to the acquisition unit 162. The acquisition unit 162 receives the light to form actual fingerprint information and transmits the fingerprint image to the recognition mechanism 170. For example, the acquisition unit 162 may be a photosensitive sensor 1621, and the actual fingerprint information may be the light data acquired by the photosensitive sensor 1621. The recognition mechanism 170 converts this light data into a grayscale image and compares and analyzes it with a pre-stored fingerprint grayscale image; alternatively, the acquisition unit 162 may be a camera, and the actual fingerprint information may be a fingerprint image captured by the camera. The recognition mechanism 170 converts the fingerprint image into a grayscale image and compares and analyzes it with a pre-stored fingerprint grayscale image.

[0071] Optionally, after the light source unit 161 starts for a preset time, the acquisition unit 162 completes the light acquisition, and the light source unit 161 is turned off to reduce the energy consumption of the device.

[0072] Optionally, a preset time t is provided, satisfying t≤1s. For example, the preset time can be 0.2s, 0.3s, 0.4s, 0.5s, 0.7s, etc.

[0073] In some embodiments, such as Figures 1 to 3 As shown, the light source 161 is disposed between the capacitive touch panel 151 and the camera assembly 130.

[0074] In these embodiments, the light source 161 is disposed between the capacitive touch panel 151 and the camera assembly 130, shortening the distance between the light source 161 and the capacitive touch panel 151, so that the light source 161 can effectively illuminate the capacitive touch panel 151, thereby improving the acquisition reliability of the acquisition unit 162.

[0075] Optionally, the light source 161 is fixed to the wall panel 111, or the light source 161 is fixed to the capacitive touch panel 151.

[0076] Optionally, the light source 161 is located at the edge of the capacitive touch panel 151, and the light source 161 is spaced apart from the orthographic projection of the first direction X and the lens of the camera assembly 130, so as to avoid the light source 161 affecting the imaging of the camera assembly 130.

[0077] Please see Figure 4 , Figure 4 This is a partial structural diagram of an electronic device in one embodiment.

[0078] In some embodiments, such as Figure 4 As shown, the light source 161 is arranged around the center of the capacitive touch panel 151.

[0079] In these embodiments, the light source 161 is arranged around the center of the capacitive touch panel 151 so that the light source 161 illuminates the capacitive touch panel 151 uniformly, thereby improving the acquisition reliability of the acquisition unit 162.

[0080] Optionally, the light source unit 161 may include a light source and an optical fiber, with one end of the optical fiber surrounding the capacitive touch panel 151 and the other end of the optical fiber connected to the light source.

[0081] Optionally, the light source 161 includes a plurality of LEDs forming a light strip that surrounds the capacitive touch panel 151. For example, the plurality of LEDs are arranged at equal intervals to ensure that the light source 161 uniformly illuminates the capacitive touch panel 151.

[0082] In some embodiments, such as Figure 3 and Figure 4 As shown, the light source 161 is connected to the capacitive touch panel 151 on the side facing the camera assembly 130.

[0083] In these embodiments, the light source 161 is connected to the side of the capacitive touch panel 151 facing the camera assembly 130 to shorten the distance between the light source 161 and the capacitive touch panel 151, so that the light source 161 can effectively illuminate the capacitive touch panel 151, thereby improving the acquisition reliability of the acquisition unit 162.

[0084] Optionally, the light source 161 is glued or snapped onto the side of the capacitive touch panel 151 facing the camera assembly 130 to improve the stability of the light source 161.

[0085] Please see Figure 5 , Figure 5 This is a schematic diagram of the electronic device in another embodiment.

[0086] In some embodiments, such as Figure 2and Figure 5 As shown, the wall panel 111 is provided with a second mounting hole 114 through it, the first mounting hole 113 and the second mounting hole 114 are provided at intervals, the light source part 161 is provided in the second mounting hole 114, the capacitive touch panel 151 covers the first mounting hole 113 and the second mounting hole 114, and the acquisition part 162 is provided between the capacitive touch panel 151 and the camera assembly 130.

[0087] In these embodiments, the wall panel 111 is provided with a first mounting hole 113 and a second mounting hole 114 spaced apart. The camera assembly 130 and the light source 161 are respectively disposed in the first mounting hole 113 and the second mounting hole 114. The capacitive touch panel 151 covers the first mounting hole 113 and the second mounting hole 114. When the light source 161 emits light, it can illuminate the part of the capacitive touch panel 151 covered by the first mounting hole 113, so as to facilitate the collection unit 162 to collect fingerprint information. The light source 161 disposed in the second mounting hole 114 is easy to set and can be reused from the original flash of the electronic device 100, which helps to reduce the processing difficulty of the fingerprint recognition module 140.

[0088] Optionally, in related technologies, a flash is typically provided near the camera assembly 130. The flash is used to provide an additional light source to the camera assembly 130 in low-light environments to improve the sharpness of the photo, and to reduce shadows and balance exposure when the subject is backlit.

[0089] In this embodiment, the flash lamp can be reused as the light source 161 to illuminate the transparent capacitive touch panel 151, so that the acquisition unit 162 can acquire the fingerprint image when the finger presses the capacitive touch panel 151. Furthermore, by reusing the flash lamp as the light source 161, the number of components in the fingerprint recognition module 140 can be reduced, thereby simplifying the structure of the fingerprint recognition module 140.

[0090] Optionally, the light source 161 is set independently of the flash unit of the device. In comparison, the power requirement of the light source 161 is lower than that of the flash unit. Therefore, when the light source 161 and the flash unit are set independently, it helps to reduce the power consumption of the device and improve the battery life of the electronic device 100.

[0091] Optionally, when the light source unit 161 is independent of the device's flash settings, the light source unit 161 can also provide supplemental light for the camera component 130 in low-light environments to improve the clarity of the photos.

[0092] Optionally, a plurality of second mounting holes 114 are arranged around the first mounting hole 113 so that the light source 161 can uniformly illuminate the capacitive touch panel 151, so as to facilitate the acquisition unit 162 to acquire a clear fingerprint image.

[0093] For example, two second mounting holes 114 are disposed opposite to each other on both sides of the first mounting hole 113, wherein the light source portion 161 of at least one mounting hole is reused as the flash of the device so that the light source portion 161 can uniformly illuminate the capacitive touch panel 151.

[0094] In some embodiments, such as Figures 1 to 3 As shown, the acquisition unit 162 is located on the side of the camera assembly 130 away from the screen 120, and the acquisition unit 162 is provided with a through hole, through which external light enters the camera assembly 130 via the capacitive touch panel 151 and the through hole.

[0095] In these embodiments, the acquisition unit 162 is disposed on the side of the camera assembly 130 away from the screen 120 to facilitate the acquisition unit 162 in acquiring fingerprint images and reduce the interference of external light on the acquisition unit 162. The acquisition unit 162 is provided with a through hole, and external light enters the camera assembly 130 through the capacitive touch panel 151 and the through hole, so as to avoid the acquisition unit 162 affecting the imaging of the camera assembly 130 and improve the reliability of the electronic device 100.

[0096] For example, a through hole is provided in the middle region of the acquisition unit 162, and the lens is exposed through the through hole, allowing external light to enter the setting component through the through hole.

[0097] Optionally, the camera assembly 130 includes a lens group and a lens barrel surrounding the lens group. The lens barrel is made of an opaque material and is used to prevent external light from interfering with the imaging of the lens group. In this embodiment, the acquisition unit 162 can be set independently of the lens barrel, and the acquisition unit 162 can be fixed to the end of the lens barrel facing the capacitive touch panel 151 by adhesive or snap-fit; or the acquisition unit 162 can be integrated into the lens barrel and reused on the top plate of the lens barrel.

[0098] Optionally, the acquisition unit 162 and the camera assembly 130 can be detachably connected to facilitate replacement and maintenance of the acquisition unit 162.

[0099] In some embodiments, such as Figure 2 and Figure 3 As shown, the acquisition unit 162 includes a photosensitive sensor 1621, which acquires fingerprint images. The acquisition reliability is high and the maintenance and replacement cost is low.

[0100] Optionally, when a finger presses the capacitive touchpad 151, the light source 161 emits light, the photosensitive sensor 1621 collects the light reflected or refracted by the fingerprint, and the recognition mechanism 170 converts the light information collected by the photosensitive sensor 1621 into a grayscale image and compares and analyzes it with the stored fingerprint image to complete the fingerprint recognition process.

[0101] Please see Figure 6 , Figure 6This is a partial structural diagram of an electronic device in another embodiment.

[0102] In some embodiments, such as Figure 2 and Figure 6 As shown, the acquisition unit 162 reuses the camera assembly 130, and the fingerprint recognition module 140 is configured such that when a finger presses the capacitive touchpad 151, the camera assembly 130 receives light reflected and / or refracted by the finger to generate actual fingerprint information.

[0103] In these embodiments, the acquisition unit 162 reuses the camera component 130. When a finger presses the capacitive touchpad 151, the camera component 130 directly acquires the fingerprint image, thereby reducing the number of components in the fingerprint recognition module 140, simplifying the structure of the fingerprint recognition module 140, and improving the reliability of the fingerprint recognition module 140.

[0104] Specifically, when a finger presses the capacitive touchpad 151, the light source 161 illuminates the capacitive touchpad 151. The camera component 130 directly images the fingerprint pressed on the capacitive touchpad 151 in the bright environment of the light source 161. The recognition mechanism 170 converts the fingerprint image formed by the camera component 130 into a grayscale image and compares and analyzes it with a pre-stored fingerprint image.

[0105] Optionally, a control scheme for the camera component 130 to acquire fingerprint images can be stored in the central processing unit in advance. The control scheme includes data such as the focal length, exposure, and sensitivity of the camera component 130 when acquiring fingerprint images, so as to facilitate the camera component 130 to quickly and clearly acquire fingerprint images.

[0106] Please see Figure 7 , Figure 7 This is a partial structural diagram of an electronic device in one embodiment.

[0107] In some embodiments, such as Figure 7 As shown, the sensing mechanism 150 also includes an anti-fouling layer 152, which is disposed on the side of the capacitive touch panel 151 away from the screen body 120.

[0108] In these embodiments, an anti-fouling layer 152 is provided on the side of the capacitive touchpad 151 away from the screen body 120. The anti-fouling layer 152 serves to clean the capacitive touchpad 151, thereby improving the problem that pressing the capacitive touchpad 151 with a finger causes it to become blurry, affecting the imaging quality of the camera component 130.

[0109] Optionally, the anti-fouling layer 152 is formed on the surface of the capacitive touchpad 151 by coating, pasting or magnetron sputtering.

[0110] Optionally, the antifouling layer 152 can be a nano-hydrophobic and oleophobic coating, which forms a low surface energy layer through nanomaterials (such as silica, fluorinated polymers) to make it difficult for water and oil to adhere; or the antifouling layer 152 can be vacuum-deposited, which forms a hard antifouling film by depositing magnesium fluoride, silica or diamond-like carbon in a vacuum environment; or the antifouling layer 152 can be a self-assembled monomolecular film, such as an oleophobic film formed by perfluorosilane, or a hydrophobic film formed by octadecyltrichlorosilane, etc.

[0111] Please see Figure 8 , Figure 8 This is a schematic diagram of the electronic device in another embodiment.

[0112] In some embodiments, such as Figure 8 As shown, the electronic device 100 includes at least two camera components 130 and at least two first mounting holes 113, with the at least two camera components 130 and the at least two first mounting holes 113 being arranged in a one-to-one correspondence, and the capacitive touch panel 151 covering the at least two first mounting holes 113.

[0113] In these embodiments, the electronic device 100 includes at least two camera components 130, and the at least two camera components 130 and at least two first mounting holes 113 are arranged in a one-to-one correspondence. The capacitive touch panel 151 covers the at least two first mounting holes 113, increasing the total area of ​​the capacitive touch panel 151, improving the recognition reliability of the fingerprint module, and facilitating blind fingerprint unlocking for users.

[0114] For example, the electronic device 100 may include at least two of the following: a main camera assembly, an ultra-wide-angle camera assembly, a telephoto camera assembly, and a macro camera assembly, with different types of camera assemblies 130 disposed in first mounting holes 113 spaced apart from each other.

[0115] Optionally, a capacitive touchpad 151 may be fitted over at least two first mounting holes 113, reducing the manufacturing difficulty of the capacitive touchpad 151.

[0116] Optionally, multiple capacitive touch panels 151 are respectively fitted onto each of the first mounting holes 113, reducing the overall size of the capacitive touch panel 151 and lowering the material cost of the fingerprint recognition module 140.

[0117] Please see Figure 9 , Figure 9 This is a flowchart of a fingerprint recognition method in one embodiment.

[0118] The second aspect of this application provides a fingerprint recognition method, applied to the electronic device 100 of the first aspect embodiment described above, such as... Figure 2 , Figure 3 and Figure 9 As shown, fingerprint recognition methods include:

[0119] Step S1: The capacitive touchpad 151 detects whether the user's finger is pressing it. If the capacitive touchpad 151 detects the user's finger pressing, the acquisition mechanism 160 is activated.

[0120] Step S2: The acquisition mechanism 160 acquires the actual fingerprint information of the user's finger and transmits it to the recognition mechanism 170;

[0121] Step S3: Instruct the identification mechanism 170 to compare the actual fingerprint information with the pre-stored fingerprint information. If they match, continue to execute the next instruction; if they do not match, end the process.

[0122] In the fingerprint recognition method provided in this application embodiment, a capacitive touch panel 151 covering the first mounting hole 113 is used to sense finger pressure. The capacitive touch panel 151, which is independent of the frame assembly 110 and the screen 120, has a clear structure and is convenient for blind unlocking by the user. After the capacitive touch panel 151 senses the user's finger pressure, the acquisition mechanism 160 acquires the actual fingerprint information, reducing the overall power consumption of the fingerprint recognition module 140. The recognition mechanism 170 compares the actual fingerprint information acquired by the acquisition unit 162 with the pre-stored fingerprint information to perform fingerprint recognition.

[0123] Specifically, when the capacitive touchpad 151 detects a user's finger pressing, it means that when the user's finger presses the capacitive touchpad 151, it causes a change in the capacitance value inside the capacitive touchpad 151. When the change in capacitance value exceeds a threshold, the acquisition mechanism 160 will be activated.

[0124] Optionally, in step S1, the user's finger specifically refers to the finger pressing on the capacitive touchpad 151.

[0125] Optionally, in step S2, after the acquisition mechanism 160 is started, the acquisition mechanism 160 acquires actual fingerprint information within a preset time. After the acquisition is completed, the acquisition mechanism 160 is turned off to reduce the energy consumption of the fingerprint recognition module 140.

[0126] Optionally, the identification mechanism 170 stores one or more pre-stored fingerprint information. In step S3, the identification mechanism 170 converts the actual fingerprint information into a grayscale image and compares the grayscale image with the pre-stored fingerprint information. When the similarity between the grayscale image and a pre-stored fingerprint information is equal to or greater than a threshold, the fingerprints are considered to be consistent, and the next instruction is executed. For example, the next instruction may be to turn on the screen, make a payment, etc. When the similarity between the grayscale image and a pre-stored fingerprint information is equal to or greater than a threshold, the fingerprints are considered to be inconsistent, and the fingerprint recognition process ends.

[0127] Please see Figure 10 , Figure 10 This is a flowchart of a fingerprint recognition method in one embodiment.

[0128] In some embodiments, such as Figure 2 , Figure 3 and Figure 10 As shown, the acquisition mechanism 160 includes a light source unit 161 and an acquisition unit 162 that are electrically connected to each other. The light source unit 161 is electrically connected to the capacitive touch panel 151, and the acquisition unit 162 is electrically connected to the recognition mechanism 170. In step S2,

[0129] Step S21: The light source 161 emits light to the capacitive touch panel 151;

[0130] Step S22: The acquisition unit 162 receives light reflected and / or refracted by the fingerprint to generate actual fingerprint information and transmits it to the identification mechanism 170.

[0131] In these embodiments, when a finger presses the capacitive touchpad 151, the light source 161 emits light to the capacitive touchpad 151, and the acquisition unit 162 receives the light reflected and / or refracted by the finger to generate actual fingerprint information. The reliability of fingerprint acquisition is improved through the cooperation of the acquisition unit 162 and the capacitive touchpad 151.

[0132] Optionally, in step S21, when a finger presses the capacitive touchpad 151, the light source 161 illuminates the capacitive touchpad 151, and the light passes through the capacitive touchpad 151 and is refracted and / or reflected at the fingerprint.

[0133] Optionally, in step S22, for example, the acquisition unit 162 is a photosensitive sensor 1621, and the actual fingerprint information is the light data acquired by the photosensitive sensor 1621. The recognition mechanism 170 converts this light data into a grayscale image and compares and analyzes it with a pre-stored fingerprint grayscale image; or the acquisition unit 162 is a camera, and the actual fingerprint information is the fingerprint image captured by the camera. The recognition mechanism 170 converts the fingerprint image into a grayscale image and compares and analyzes it with a pre-stored fingerprint grayscale image.
