It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, an embodiment of the present invention discloses an electronic device, which includes a housing 100, a camera 220, a driving mechanism 300, and a fingerprint identification portion.

Wherein, the housing 100 has a mounting hole provided with a light-transmitting cover plate 210. The camera 220 is installed in the housing 100, the camera 220 is disposed toward the transparent cover 210, and the projection of the camera 220 in the direction of the optical axis thereof is located in the transparent area of the transparent cover 210, so as to ensure that the camera 220 can shoot the fingerprint image of the living body located outside the transparent cover 210. The driving mechanism 300 is installed in the casing 100, the driving mechanism 300 is connected with the camera 220 to drive the camera 220 to move between a first position and a second position along the direction of the optical axis of the camera, when the camera 220 is located at the first position, the distance between the camera 220 and the transparent cover plate 210 is a first distance, when the camera 220 is located at the second position, the distance between the camera 220 and the transparent cover plate 210 is a second distance, and the first distance is greater than the second distance. Fingerprint identification portion installs in casing 100, and fingerprint identification portion is connected with camera 220, and fingerprint identification portion can carry out fingerprint identification according to the fingerprint image that camera 220 was shot under being located the condition of primary importance.

Under the condition that the electronic device adopts the technical scheme, the camera 220 can move the position of the camera relative to the light-transmitting cover plate 210 under the action of the driving mechanism 300. Wherein, under the condition that camera 220 is located the second position, camera 220 is minimum with the interval of printing opacity apron 210 in the optical axis direction of camera 220, be the second interval, along with camera 220 removes to the first position from the second position, camera 220 is crescent with the interval of printing opacity apron 210 on the optical axis direction of camera 220, when camera 220 removes to the first position, camera 220 reaches the biggest with the interval of printing opacity apron 210 on the optical axis direction of camera 220, be first interval, the area of camera 220 field of view region on printing opacity apron 210 this moment is the biggest, and then can acquire the fingerprint image of bigger area.

It is known that, in the case where the angle of view of the camera 220 is not changed and the position of the camera 220 is fixed, the range of view of the living body located outside the transparent cover 210 by the camera 220 is also fixed. The viewing range of the camera 220 can be changed by changing the distance between the camera 220 and the living body outside the transparent cover 210, and the larger the distance between the camera 220 and the living body is, the larger the viewing range of the camera 220 is, as shown in fig. 1. Therefore, in the process of acquiring the fingerprint image of the living body outside the transparent cover plate 210 by using the camera 220, the viewing range of the camera 220 can be enlarged by increasing the distance between the camera 220 and the living body outside the transparent cover plate 210, and then the camera 220 can acquire the fingerprint image of a larger area, the fingerprint identification difficulty can be reduced based on the fingerprint image of the larger area in the process of identification of the fingerprint identification part, the accuracy rate of the fingerprint identification is improved, the fingerprint identification speed can be improved to a certain extent, and the user experience is improved.

The housing 100 may be made of a hard material such as metal or plastic, the shape and size of the mounting hole may be determined according to the shape and size of the light-transmissive cover plate 210, and the light-transmissive cover plate 210 may be in sealing fit with the mounting hole to ensure that the electronic device has high air tightness.

The installation position of the camera 220 is various, and the electronic device is generally provided with a display module. Alternatively, the camera 220 may be disposed inside the display module, i.e., the camera 220 in the form of a screen. Alternatively, there is a gap between the installation position of the camera 220 and the position of the display module, and the camera 220 may face any one of the two sides of the casing 100, similar to the front camera or the rear camera of the electronic device. By positioning the projection of the camera 220 in the direction of the optical axis thereof in the light-transmitting region of the light-transmitting cover 210, it is ensured that the camera 220 can acquire the fingerprint image of the living body located outside the light-transmitting cover 210 and facing itself, so that the fingerprint recognition portion performs fingerprint recognition by means of the aforementioned image.

The positions of the mounting holes are also varied depending on the mounting position of the camera 220. Under the condition that camera 220 is installed in the inboard of display module assembly, the mounting hole is the installing port of display module assembly promptly. At this moment, the light-transmitting cover plate 210 can be the hard light-transmitting plate at the outermost side of the display module, the light-transmitting cover plate 210 can be integrally formed with other structures of the display module, and in order to ensure that the camera 220 installed at the inner side of the display module can acquire images of living bodies outside the display module, a silk screen opening can be formed outside the corresponding area of the display module, the light-transmitting cover plate 210 is ensured to have a light-transmitting area, and then the camera 220 is ensured to acquire images of the living bodies outside the light-transmitting cover plate 210. And in the case where the camera 220 is similar to a front camera or a rear camera, the light-transmissive cover 210 may be a rigid light-transmissive plate. The transparent cover plate 210 may also provide protection for the camera 220, for example, the transparent cover plate 210 may be a sapphire glass plate, and at least a portion of the transparent cover plate 210 has a light-transmitting capability.

The driving mechanism 300 may be a linear motor, or may also be a rotary motor, a pneumatic telescopic element, a hydraulic telescopic element, or the like, and a driving head (i.e., a moving part of the driving mechanism 300) of the driving mechanism 300 is connected to the camera 220 to drive the camera 220 to move between the first position and the second position. The specific values of the first distance and the second distance may be selected according to the actual conditions of the internal space of the electronic device, and are not limited herein.

The fingerprint identification portion specifically can be the fingerprint identification treater, fingerprint identification portion and camera 220 communication connection to the fingerprint image of shooing in the first position with the help of camera 220 carries out fingerprint identification work. Because camera 220 can acquire the fingerprint image of bigger area when first position, and then when making fingerprint identification portion carry out fingerprint identification based on the fingerprint image of bigger area, fingerprint identification's the degree of difficulty is less relatively, and degree of accuracy and recognition speed are also relatively higher.

Optionally, the camera 220 may be a wide-angle camera 220, and by increasing the viewing angle of the camera 220, the viewing range of the camera 220 may also be enlarged, so as to further increase the area of the fingerprint image acquired by the camera 220. Specifically, in the case that the camera 220 is the wide-angle camera 220, it can be ensured that when the camera 220 is at the first position, the field of view area of the camera 220 on the transparent cover 210 is also located in the transparent area by increasing the area of the transparent cover 210. Parameters such as the focal length and the angle of view of wide-angle camera 220 may be determined according to actual conditions, for example, the angle of view of wide-angle camera 220 may be greater than 110 °.

In order to ensure that the field of view of the camera 220 on the light-transmitting panel is located in the light-transmitting region even when the camera 220 is at the first position, the area of the light-transmitting region of the light-transmitting cover plate 210 needs to be increased to meet the requirement, and if the camera 220 is installed inside the display module of the electronic device, the area of the silk-screen hole on the display module needs to be increased in order to increase the area of the light-transmitting region, but the area will have a great adverse effect on the display effect of the display module.

Simultaneously, when camera 220 installs the inboard at the display module assembly, because the light transmission performance of display module assembly is relatively poor, the fingerprint image of gathering in order to guarantee camera 220 has higher definition, in order to do benefit to fingerprint identification, at fingerprint identification's in-process, the fingerprint identification region of display module assembly usually need to light, the fingerprint identification region is the region at silk screen printing trompil place promptly, in order to promote the regional luminance of fingerprint identification, make camera 220 can acquire comparatively clear fingerprint image. However, in the use of electronic equipment, fingerprint identification operation is comparatively frequent, and this makes the fingerprint identification region also frequently lighted in the display module assembly, compares in other regions in the display module assembly, and the life in fingerprint identification region can shorten more, appears burning the screen phenomenon easily.

Therefore, the mounting position of the camera 220 can be made similar to that of the front camera or the rear camera, in which case the mounting position of the display module is different from the opening position of the mounting hole, the display module is mounted on the housing 100, and the mounting hole is spaced apart from the display module.

Under the condition of adopting above-mentioned structure, can guarantee that camera 220 is even when being located the primary importance through the regional area of the light transmission on the increase printing opacity apron 210, camera 220 is also all located the light transmission regional in the visual field region on printing opacity apron 210, and then guarantees that the area of the fingerprint image that camera 220 obtained is great.

An optional embodiment is that, camera 220 can be the rear camera of electronic equipment, and camera 220 and display module set up back to back, and printing opacity apron 210 lid is established outside camera 220, and camera 220 sets up towards printing opacity apron 210, and under this condition, no matter what kind of size is increased to in the light transmission area on the printing opacity apron 210, can not produce adverse effect to the display effect of display module basically. Also, the camera 220 may be used for conventional photographing work, for example, photographing a human image or a scene, etc.

More specifically, camera head 220 may be mounted on a bracket 240, and bracket 240 may be secured to housing 100 by glue 260. Can fill up between camera 220 and the support 240 and be equipped with the cotton 250 of bubble, prevent that the phenomenon of colliding with from appearing in camera 220 in the motion process, and the cotton 250 stability that can also promote camera 220 of bubble. The light-transmissive cover plate 210 may also be secured at the mounting holes by glue 260.

In the fingerprint recognition process, a living body part having fingerprint information, such as a finger of a user, may be brought close to the transparent cover 210, and a fingerprint area of the finger may be located within a viewing range of the camera 220, at this time, the camera 220 may obtain a fingerprint image with a larger area, and in order to increase the area of the fingerprint image obtained by the camera 220, the living body part may be brought closer to the camera 220, for example, the finger may be attached to an outer surface of the transparent cover 210.

However, as the finger of the user gradually approaches the transparent cover 210, the finger may block the light, which may reduce the amount of light reflected into the camera 220, and this may definitely cause the sharpness of the fingerprint image obtained by the camera 220 to be poor. When the finger completely covers the light-transmitting area, the camera 220 may not normally capture the fingerprint image.

Optionally, through the regional area of further increase printing opacity, can guarantee that even if the finger is attached not all cover the printing opacity region outside printing opacity apron 210, and then the outer light of printing opacity apron 210 can pass in printing opacity apron 210 gets into electronic equipment, then reflects to the finger again, and finally, under the reflection of finger, guarantee that camera 220 can acquire comparatively clear fingerprint image.

Or, a light reflection device may be further added in the electronic device to reflect light generated by a display module and other components with light-emitting capability in the electronic device to the living body outside the transparent cover plate 210, which may also ensure that the camera 220 can normally acquire a fingerprint image of the living body outside the transparent cover plate 210.

Optionally, the electronic device disclosed in the embodiment of the present invention may further include a light supplement lamp 230, the light supplement lamp 230 is installed on one side of the camera 220, the light supplement lamp 230 is disposed toward the transparent cover plate 210, and a projection of the light supplement lamp 230 in the optical axis direction of the camera 220 is located in the transparent area, so that in a process of acquiring a fingerprint image by the camera 220, a living body located outside the transparent cover plate 210 may be illuminated by turning on the light supplement lamp 230, and it is ensured that the camera 220 can acquire a fingerprint image with a higher definition. Specifically, the fill light 230 may be a flash light, and its power and other parameters may be determined according to actual requirements.

Optionally, the light supplement lamp 230 may be an infrared light supplement lamp 230, and since infrared rays do not belong to visible light, a user does not pay attention to the infrared light supplement lamp 230 even if the infrared light supplement lamp 230 is in an on state in a process of performing fingerprint identification by using the camera 220; in addition, the penetrating power of infrared ray is stronger, and then can prevent other factors interference from illuminating the live body outside the printing opacity apron 210, guarantees that the live body can reflect sufficient light to the camera 220 in, and then makes camera 220 can acquire the fingerprint image of high definition.

In the case that the fill light 230 is an infrared fill light 230, the light-transmitting region may include a double-pass region 211 and a single-pass region 212, wherein the single-pass region 212 is disposed around the double-pass region 211. The single pass region 212 and the double pass region 211 can both pass infrared light, while the double pass region 211 can also pass visible light, and the single pass region 212 can block visible light.

With the above structure, the area of the light-transmitting region on the light-transmitting cover 210 that can be observed by naked eyes is relatively small, and the degree of matching between the light-transmitting cover 210 and the housing 100 of the electronic device is high. In order to ensure that the camera 220 can acquire both a fingerprint image with a large area and a scene or a portrait with a large area in a conventional shooting process, optionally, as shown in fig. 1, when the camera 220 is located at the first position, the field of view area of the camera 220 on the transparent cover plate 210 may include a single pass area 212 and a double pass area 211; with the camera 220 in the second position, the field of view area of the camera 220 on the light transmissive cover 210 may be made to include the pass-through region 211.

In the working process of the camera 220, when a fingerprint image needs to be shot, the camera 220 can be moved to the first position, infrared light emitted by the infrared light supplement lamp 230 located in the light-transmitting cover plate 210 passes through the single-pass area 212 and the double-pass area 211 to irradiate the living body outside the light-transmitting cover plate 210, the infrared light is reflected on the surface of the living body, the infrared light can pass through the single-pass area 212 and the double-pass area 211 again to irradiate into the camera 220 in the light-transmitting cover plate 210, and a corresponding fingerprint image is formed in the camera 220. Under the condition that the camera 220 is located at the first position, the view field area of the camera 220 on the transparent cover plate 210 is the largest, and the area of the fingerprint image acquired by the camera 220 is relatively large.

Accordingly, in order to enable the camera 220 to obtain a scene or a portrait with a large area during the normal shooting, when the camera 220 performs the normal shooting, the camera 220 can be moved to the second position by the driving mechanism 300, and since the camera 220 is located at the second position, the field of view area of the camera 220 on the light-transmitting cover plate 210 includes the two-way area 211, it is ensured that the visible light can enter the camera 220 through the two-way area 211, so that a scene or a portrait with a large area is formed.

Specifically, the transparent cover plate may be made of a transparent material, and the single-pass area 212 may be formed on the transparent cover plate by means of infrared ink, and the single-pass area 212 is disposed around the dual-pass area 211. The size of both the single pass region 212 and the double pass region 211 may be determined according to parameters such as the viewing angle of the camera 220, the actual value of the first position and the second distance, and the like.

Further, the dual-pass area 211 may have a circular structure, and the single-pass area 212 may have an annular structure, so that when the camera 220 is located at the first position, the boundary of the field of view area of the camera 220 on the transparent cover 210 may be located at the edge of the single-pass area 212 away from the dual-pass area 211. By adopting the technical scheme, the view range of the camera 220 at the first position can be maximized. Correspondingly, under the condition that the camera 220 is located at the second position, the boundary of the field of view area of the camera 220 on the light-transmitting cover plate 210 can be located at the joint of the single-pass area 212 and the double-pass area 211, and by adopting the technical scheme, the view range of the camera 220 at the second position can be maximized.

Optionally, the driving mechanism 300 may include a power supply substrate 310 and an SMA motor 320, the SMA motor 320 is connected to the power supply substrate 310, a mounting groove is provided on a supporting surface of the SMA motor 320, and an end of the camera 220 facing away from the transparent cover plate 210 is fixedly mounted in the mounting groove.

The core component of the SMA motor 320 is a shape memory metal, and the greatest characteristic is that when the temperature of the material changes, the shape of the material changes, and the deformation quantity and the temperature have a corresponding relation. And has the conductivity and ductility of the metal. When current I passes through the SMA part, the resistance of the SMA part is R, the heating power is P, and according to the formula P, the material can generate heat, and the SMA part deforms in a specific direction after the temperature rises. Based on the correspondence between the deformation quantity and the temperature, the heating power is in direct proportion to the square of the current, namely the deformation quantity of the SMA material can be controlled by controlling the magnitude of the current. The SMA motor 320 is based on the above principle, and changes the shape of the internal structural components by controlling the current to move the internal movable components in a particular direction.

An SMA (shape memory alloy) motor 320 is mounted on the power supply substrate 310 and is fixedly connected to the power supply substrate 310. The power supply substrate 310 provides a mounting base for the SMA motor 320 and also provides power for the operation of the SMA motor 320. In order to facilitate the assembly of the power supply substrate 310 in the terminal device, the power supply substrate 310 may be a flexible circuit board. The electronic device may be provided with a control unit, so that the control unit controls the current of the SMA motor 320 to generate corresponding actions during the operation of the electronic device.

Further, the electronic device disclosed in the embodiment of the present invention may further include a detection portion 400 and a control portion, the detection portion 400 is mounted on the housing 100, the control portion is connected to the driving mechanism 300, during the use of the electronic device, the detection portion 400 may detect a target parameter of a living body outside the transparent cover 210, and the control portion may control the driving mechanism 300 to drive the camera 220 to move to the first position when the detection value of the target parameter is within a preset value range.

In the course of normal photographing by the camera 220, the living body to be photographed is generally far from the camera 220, and in the course of fingerprint recognition, as described above, in order to ensure high recognition accuracy, it is generally necessary to bring the finger of the user close to the camera 220. Therefore, by comparing the detection value of the distance between the living body outside the transparent cover plate 210 and the camera 220 detected by the detection part 400 with the preset value range, when the detected value of the distance is within the preset value range, it can be considered that the user has a requirement for fingerprint identification operation, and the control part controls the driving part to drive the camera 220 to move to the first position, so that the camera 220 can acquire a fingerprint image with a larger area.

Specifically, the target parameter may be a distance, the detection part 400 is a distance detection part 400, and optionally, the distance detection part 400 is a distance detection sensor; the distance detection unit 400 can detect the distance between the living body outside the transparent cover 210 and the camera 220 to obtain a detection value of the distance, and the preset value range can be determined according to actual conditions.

Alternatively, the target parameter may also be temperature or pressure, and the preset value range may correspondingly be a temperature range or a pressure range, in which case, the detecting portion 400 may be a temperature sensor or a pressure sensor. Of course, the target parameter may also be other physical quantities, and is not listed here in order to consider the brevity of the text.

In addition, in order to promote the accurate degree of judgement result, detection portion 400 can be a plurality of to through the mode that detects multiple target parameter, promote the judgement precision, when preventing that the user from not having the demand of carrying out the fingerprint identification operation, open camera 220, the problem that camera 220 triggers by mistake appears.

As described above, the camera 220 further has a function of normally capturing images of scenes or people, and in order to enable the camera 220 that has completed the fingerprint image capturing operation to quickly enter the normal capturing state, optionally, the control unit may further control the driving mechanism 300 to drive the camera 220 to move to the second position when the target parameter is outside the preset value range.

In an optional scheme, the control method disclosed in the embodiment of the present invention may further include:

and S3, controlling the camera 220 to move to the second position when the shooting message is the second shooting message.

After the control method is adopted, the electronic device may control the driving mechanism 300 to drive the camera 220 to move to the corresponding position according to different shooting messages. Specifically, first shooting message is fingerprint image shooting message, under the condition that needs camera 220 to shoot fingerprint image, through making camera 220 remove to primary importance, also makes camera 220 more far away from printing opacity apron 210 for the area of the fingerprint image that camera 220 acquireed is bigger, thereby reduces the fingerprint identification degree of difficulty, promotes fingerprint identification rate of accuracy and recognition speed. The second photographing message is a normal image photographing message, and the range of the scene or the portrait photographed by the camera 220 can be made larger by controlling the camera 220 to move to the second position.

The embodiment of the invention also discloses electronic equipment which comprises a receiving module and a control module, wherein the receiving module can receive the shooting message, and the control module is used for controlling the camera 220 to move to the first position under the condition that the shooting message is the first shooting message. The control module may be further configured to control the camera 220 to move to the second position if the photographing message is the second photographing message.

Under the condition that camera 220 is located the first position, the area of the fingerprint image that camera 220 acquireed is great, and under the condition that camera 220 is located the second position, the area of the scene or the conventional images such as portrait that camera 220 acquireed is great, and not only the degree of difficulty of guaranteeing electronic equipment fingerprint identification is lower, and fingerprint identification speed and rate of accuracy are higher, can also promote the image capture effect of electronic equipment in the conventional shooting process.
