Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram illustrating an apparatus having an iris recognition function according to an exemplary embodiment. As shown in fig. 1, the apparatus includes: infrared emitter 11, iris image capture sensor 12 and display screen 13.
In a possible implementation manner, the device may be a mobile terminal such as a mobile phone, a tablet computer, or a notebook computer, which is not limited herein.
The infrared emitter 11 is configured to emit infrared rays.
The iris image capture sensor 12 is configured to capture an iris image when the infrared emitter 11 emits infrared rays.
The display screen 13 is covered above the infrared emitter 11 and the iris image collecting sensor 12, and the display screen 13 has a certain transparency. Accordingly, the display screen 13 may also be referred to as a transparent screen, a transparent display screen, or the like.
Wherein, the transparency can represent the degree of light transmission of the object. In general, the higher the transparency of the display screen 13, the better the light transmission performance.
In one example, after the user selects an iris recognition function in a device such as a mobile phone, the device transmits an iris recognition instruction to the infrared transmitter 11. The infrared transmitter 11 transmits infrared rays in the case of receiving the iris recognition command. The infrared rays emitted from the infrared emitter 11 are emitted through the display screen 13. If the infrared ray reaches an object to be measured, such as a human eye, it is reflected. The reflected light reaches the iris image pickup sensor 12 through the display screen 13. The iris image capture sensor 12 may generate an iris image from the received reflected light.
In this embodiment, after the user selects the iris recognition function in the device such as the mobile phone, the device may also send an iris recognition instruction to the iris image capturing sensor 12 to control the iris image capturing sensor 12 to start capturing the iris image. In addition, the iris image capturing sensor 12 may start capturing the iris image again when detecting that the infrared emitter 11 emits infrared rays.
In one possible implementation, the display screen may include, but is not limited to, the following categories: a transparent LCD (Liquid Crystal Display), a transparent LED (Light Emitting Diode) Display, and a transparent OLED (Organic Light Emitting Diode) Display.
It will be appreciated by those skilled in the art that the present disclosure has the display screen 13 overlaid over the infrared emitter 11 and the iris image capture sensor 12 for indicating that the display screen 13 does not have the infrared emitter 11 and the iris image capture sensor 12 directly exposed to the exterior of the device.
It should be noted that the device is further provided with an iris recognition module. The iris recognition module is configured to recognize the identity of the user from the iris image capture sensor 12. The iris recognition module can be integrated in a processing chip, and can also be realized by combining logic instructions with a general-purpose processor.
In the embodiment, the display screen 13 with a certain transparency is covered above the infrared emitter 11 and the iris image acquisition sensor 12, so that the display screen of the device has a larger display area and a larger touch area without separately opening holes on the display screen of the device under the condition of realizing the iris recognition function.
In a possible implementation, the infrared emitter 11 and the iris image acquisition sensor 12 are arranged side by side in the device near one of the two ends of the device.
For example, as shown in fig. 1, the infrared emitter 11 and the iris image pickup sensor 12 may be disposed side by side in the apparatus near the top or bottom end of the apparatus. In this way, the main display area in the middle of the display screen 13 is not disturbed, thereby reducing the influence of the infrared emitter 11 and the iris image collecting sensor 12 on the display effect of the display screen 13 during operation.
In another possible implementation, the infrared emitter 11 and the iris image acquisition sensor 12 may be arranged side by side in the device below the area of the status bar corresponding to the display page of the display screen 13. The status bar may be used to display a virtual key of a control command for the application program window or information of the application program window.
It should be noted that, as required, the infrared emitter 11 and the iris image collecting sensor 12 may be disposed at other positions in the device by those skilled in the art, and are not limited herein.
In the implementation mode, the display screen 13 of the device has certain transparency, and the display screen 13 covers the infrared emitter 11 and the iris image acquisition sensor 12, so that the normal implementation of the iris recognition function is not affected. Therefore, the area of the display screen 13 covering the infrared emitter 11 and the iris image acquisition sensor 12 is not required to be opened, so that the display screen 13 of the device has a larger display area and a larger touch area.
In one possible implementation, the iris image capture sensor 12 may be a front-facing camera. Therefore, the front camera has the functions of iris image acquisition and camera shooting, the number of elements in the equipment is reduced, and the internal space of the equipment can be effectively increased.
In one possible implementation, the full extent of the display screen 13 may have both touch functionality and display functionality.
In another possible implementation, the entire area of the display screen 13 has a display function, and a partial area of the display screen 13 has a touch function, wherein the partial area is an area covered except for the position of the iris image capture sensor 12.
Fig. 2 is a schematic structural diagram illustrating an apparatus having an iris recognition function according to another exemplary embodiment. As shown in fig. 2, the apparatus includes: infrared emitter 11, iris image acquisition sensor 12, display screen 13 and front camera 15. Components in fig. 2 that are numbered the same as those in fig. 1 have the same functions, and detailed descriptions of these components are omitted for the sake of brevity.
In a possible implementation manner, the device may be a mobile device such as a mobile phone, a tablet computer, or a notebook computer, and is not limited herein.
As an example of the present embodiment, as shown in fig. 2, the apparatus further includes a front camera 15, wherein the front camera 15 and the iris image capture sensor 12 are independently provided below the display screen 13, respectively.
In one possible implementation, as shown in fig. 2, the front-facing camera 15, the infrared emitter 11 and the iris image acquisition sensor 12 are arranged side by side near one of the two ends of the device.
For example, as shown in fig. 2, the front camera 15, the infrared emitter 11 and the iris image capture sensor 12 may be disposed side by side in the apparatus near the top or bottom end of the apparatus. In this way, the main display area in the middle of the display screen 13 is not disturbed, thereby reducing the influence of the front camera 15, the infrared emitter 11 and the iris image collecting sensor 12 on the display effect of the display screen 13 during the working process.
In another possible implementation, the infrared emitter 11, the iris image acquisition sensor 12 and the front camera 15 are arranged side by side in the device below the area of the status bar corresponding to the display page of the display screen 13. The status bar may be used to display information of a virtual key or a program window of a control command for an application program window.
In the device of the embodiment, the display screen 13 has a certain transparency, and the display screen 13 covers the infrared emitter 11, the iris image acquisition sensor 12 and the front camera 15, so that the normal implementation of the iris recognition function is not affected. Therefore, under the condition of realizing the iris recognition function, holes do not need to be formed in the area, which covers the infrared emitter 11 and the iris image acquisition sensor 12, of the display screen 13 of the device, so that the display screen 13 of the device has a larger display area and a larger touch area.
Fig. 3 is a flow chart illustrating a method of iris recognition according to an example embodiment. As shown in fig. 3, the method includes steps S101 to S104.
In step S101, determining an infrared emission power of the infrared emitter according to a transparency of the display screen;
in step S102, infrared rays are emitted with infrared ray emission power;
in step S103, collecting infrared rays reflected by the target to be measured to obtain an iris image of the target to be measured;
in step S104, the user identity of the target to be detected is identified according to the iris image.
As an example of the present embodiment, determining the infrared emission power of the infrared emitter 11 according to the transparency of the display screen 13 may include: increasing the infrared emission power of the infrared emitter 11 according to the transparency of the display screen 13
For example, if the transparency of the display screen 13 is 40% transmission of infrared light, the infrared emission power of the infrared emitter 11 can be increased by 20% compared to the emission power in vacuum.
For example, if the transparency of the display screen 13 is 80% transmissive to infrared light, the infrared emission power of the infrared emitter 11 may be increased by 2% compared to the emission power in vacuum.
As another example of the present embodiment, determining the infrared emission power of the infrared emitter 11 according to the transparency of the display screen 13 may include: a function model corresponding to the transparency of the display screen 13 and the infrared emission power of the infrared emitter 11 is preset, and the infrared emission power of the infrared emitter 11 is determined according to the transparency of the display screen 13 and the function model. It should be noted that, those skilled in the art can select an appropriate function model according to needs, and the function model is not limited herein.
The embodiment determines the infrared ray emission power of the infrared emitter based on the transparency of the display screen, so that the infrared ray has stronger penetrating power, and a better iris recognition effect can be obtained even under the condition that the display screen is not completely transparent.
As an example of this embodiment, identifying the user identity of the target to be detected according to the iris image may include: the iris image from the iris acquisition sensor 12 is processed to determine the processed iris image, and the user identity is determined according to the processed iris image and the iris image template library. The iris template image library comprises the corresponding relation between each iris template image and each user identity information.
In a possible implementation manner, if an iris template image matching the processed iris image exists in the template library, the user identity may be determined to be a legal user identity.
In another possible implementation manner, if there is no iris template image matching the processed iris image in the template library, the user identity may be determined to be an illegal user identity.
It should be noted that, a person skilled in the art may select a method for processing an iris image and recognizing the iris image according to needs, and the method is not limited herein.
In the case of realizing the iris recognition function, the display screen of the device does not need to be separately perforated, so that the display screen of the device has a larger display area and a larger touch area.
