背景技术Background technique
虹膜识别一般需要红外光源辅助虹膜摄像头获取清晰的虹膜图像，由于不同人种虹膜颜色不同，适用的红外光源的波长不同，采用单一波长的红外光源适用性较差。为此，可以设置多个工作波长不同的红外光源，然而，如此，如何选择并启动对应工作波长的红外光源成为新的问题。Iris recognition generally requires an infrared light source to assist the iris camera to obtain a clear iris image. Due to the different iris colors of different races, the applicable infrared light source has different wavelengths, and the applicability of a single-wavelength infrared light source is poor. To this end, multiple infrared light sources with different working wavelengths can be provided. However, how to select and activate the infrared light source corresponding to the working wavelength becomes a new problem.

The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.
请参阅图1和图2，本发明实施方式的红外光源组件的控制方法，包括以下步骤：Referring to Fig. 1 and Fig. 2, the control method of the infrared light source assembly according to the embodiment of the present invention includes the following steps:
S10：通过可见光摄像头采集人脸图像；S10: collecting face images through a visible light camera;
S20：根据人脸图像获取虹膜颜色；和S20: Obtain iris color according to the face image; and
S30：根据虹膜颜色启动至少二红外光源之一。S30: Activate one of at least two infrared light sources according to iris color.
本发明实施方式的电子装置1000，电子装置1000包括虹膜识别模组100、可见光摄像头200和处理器300。虹膜识别模组100包括红外光源组件10。红外光源组件10至少包括两组红外光源，至少两组红外光源的工作波长不同。作为例子，本发明实施方式的控制方法，可以由本发明实施方式的电子装置1000实现，并应用于电子装置1000。An electronic device 1000 according to an embodiment of the present invention includes an iris recognition module 100 , a visible light camera 200 and a processor 300 . The iris recognition module 100 includes an infrared light source assembly 10 . The infrared light source assembly 10 includes at least two groups of infrared light sources, at least two groups of infrared light sources have different operating wavelengths. As an example, the control method in the embodiment of the present invention may be realized by the electronic device 1000 in the embodiment of the present invention and applied to the electronic device 1000 .
其中步骤S10-S30可以由处理器300实现。也即是说，可见光摄像头200用于采集人脸图像；处理器300用于处理人脸图像以获取虹膜颜色；并根据虹膜颜色启动至少二红外光源之一。The steps S10-S30 may be implemented by the processor 300. That is to say, the visible light camera 200 is used to collect the face image; the processor 300 is used to process the face image to obtain iris color; and activate one of at least two infrared light sources according to the iris color.
虹膜识别组件100还包括红外摄像头20，红外摄像头20用于接收作为有效光源的红外光源发射的红外光在虹膜的反射光线以形成虹膜图像。红外光源组件10的照明范围、红外摄像头20的视场和可见光摄像头200的视场至少部分重叠。The iris recognition component 100 also includes an infrared camera 20, which is used for receiving the reflected light of the infrared light emitted by the infrared light source as an effective light source on the iris to form an iris image. The illumination range of the infrared light source assembly 10 , the field of view of the infrared camera 20 and the field of view of the visible light camera 200 overlap at least partially.
可以理解，红外摄像头20和可见光摄像头200用于采集人眼的相关图像，而红外光源组件10则用于在虹膜识别时提供必要的红外光。因此，红外光源组件10的照明范围、红外摄像头20的视场和可见光摄像头200的视场应至少部分重叠从而实现虹膜识别的必要步骤。It can be understood that the infrared camera 20 and the visible light camera 200 are used to collect relevant images of human eyes, while the infrared light source assembly 10 is used to provide necessary infrared light for iris recognition. Therefore, the illumination range of the infrared light source assembly 10 , the field of view of the infrared camera 20 and the field of view of the visible light camera 200 should at least partially overlap so as to realize the necessary steps of iris recognition.
随着信息安全重要性的提升，越来越多的消费电子设备中对信息进行加密以保护用户的个人信息安全，并在通过相应的验证方式获得获取相应信息与操作的权限。验证方式通常包括有字符密码、图案密码等文字图案密码，然而这种密码通常容易破解，从而使得加密失效。此外，部分电子设备如手机、平板电脑等还提供指纹作为加密方式，用户通过指纹识别进行验证，指纹虽然具有较强的差异性，但易于被他人窃取并制作成如指模等假指纹进行验证，同样不利于信息的安全。在这种情况下，虹膜识别技术作为一种安全性更高的验证方式开始被一些电子设备所采用。With the increasing importance of information security, more and more consumer electronic devices encrypt information to protect users' personal information security, and obtain permission to obtain corresponding information and operations through corresponding verification methods. Verification methods usually include text and pattern passwords such as character passwords and pattern passwords. However, such passwords are usually easy to crack, thus making the encryption invalid. In addition, some electronic devices such as mobile phones and tablet computers also provide fingerprints as an encryption method. Users can verify through fingerprint identification. Although fingerprints have strong differences, they are easy to be stolen by others and made into fake fingerprints such as fingerprints for verification. , which is also not conducive to information security. In this case, iris recognition technology has begun to be adopted by some electronic devices as a more secure verification method.
虹膜识别是通过对比虹膜图像特征之间的相似性来确定用户身份，虹膜信息具有唯一性，并且不易复制，安全性较高。Iris recognition is to determine the identity of the user by comparing the similarity between iris image features. Iris information is unique, not easy to copy, and has high security.
虹膜识别一般需要经过虹膜图像获取、虹膜图像处理以及虹膜图像识别的过程。Iris recognition generally needs to go through the processes of iris image acquisition, iris image processing and iris image recognition.
在虹膜图像获取的过程中，需要由专门的虹膜识别模组进行采集，一般地，虹膜识别模组包括摄像头以及光源，其中为保护人眼安全以及获取纹理丰富的虹膜图像，光源选择红外光，相应地，摄像头选择红外摄像头。In the process of iris image acquisition, it needs to be collected by a special iris recognition module. Generally, the iris recognition module includes a camera and a light source. In order to protect the safety of human eyes and obtain iris images with rich textures, the light source is infrared light. Correspondingly, the camera selects an infrared camera.
不同人种的虹膜颜色通常不同，例如欧美白种人的虹膜颜色通常是蓝绿色，而亚洲的黄种人的虹膜颜色通常是黑色。不同颜色的虹膜对同一工作波长的响应效率及效果均是不同的，例如对于蓝绿色的虹膜采用700nm波长的可见光也可获取虹膜图像，然而对于黑色的虹膜来说，则无法成像。The iris color of different races is usually different. For example, the iris color of European and American Caucasians is usually blue-green, while the iris color of Asian yellow people is usually black. Different colors of irises have different response efficiencies and effects to the same working wavelength. For example, visible light with a wavelength of 700nm can also be used to obtain iris images for blue-green irises, but for black irises, it cannot be imaged.
可以理解，当虹膜识别模组中仅设置单一工作波长的红外光源时，通常需折中选择，对于某一特定颜色的虹膜来说，都不是最佳选择。It can be understood that when only an infrared light source with a single working wavelength is installed in the iris recognition module, a compromise is usually required, and neither is the best choice for an iris of a certain color.
本发明实施方式的红外光源组件10，包括至少两组红外光源，并且至少两组红外光源的工作波长不同，如此，可根据用户虹膜的实际情况，选择与虹膜颜色相匹配的最佳工作波长的红外光源发射红外光，从而获取效果更加的虹膜图像。The infrared light source assembly 10 of the embodiment of the present invention includes at least two groups of infrared light sources, and the operating wavelengths of at least two groups of infrared light sources are different. In this way, the optimal operating wavelength that matches the iris color can be selected according to the actual situation of the user's iris. The infrared light source emits infrared light to obtain a more effective iris image.
可以理解，红外摄像头20的图像传感器覆盖有红外滤光片，只能够使红外光透过而成黑白图像，然而获取人种信息无论通过肤色或虹膜颜色或其他颜色信息均需要通过处理彩色图像实现。因此，需要配合可见光摄像头200。可见光摄像头200也即是传统的具有RGB滤光片的摄像头，一般地，可以是电子装置1000的前置摄像头。It can be understood that the image sensor of the infrared camera 20 is covered with an infrared filter, which can only transmit infrared light to form a black-and-white image. However, obtaining ethnic information, whether through skin color or iris color or other color information, requires processing color images. . Therefore, it is necessary to cooperate with the visible light camera 200 . The visible light camera 200 is a traditional camera with RGB filters, generally, it may be a front camera of the electronic device 1000 .
通过可见光摄像头200对用户人脸成像，对人脸图像进行处理获取虹膜颜色，进而根据虹膜颜色控制与该虹膜颜色对应的工作波长的红外光源启动以进行虹膜识别。The user's face is imaged by the visible light camera 200, and the iris color is obtained by processing the face image, and then the infrared light source corresponding to the working wavelength of the iris color is controlled according to the iris color to activate for iris recognition.
综上所述，本发明实施方式的红外光源组件的控制方法和电子装置1000，通过可见光摄像头200与虹膜识别模组100的配合，在虹膜识别前通过可见光摄像头200获取虹膜颜色信息，并根据虹膜颜色启动虹膜识别模组100中相应波长的红外光源以进行虹膜识别，针对不同人种的用户，启动不同工作波长的红外光源，一方面增加了虹膜识别模组的适用性，另一方面提高了虹膜识别的效率。To sum up, the control method of the infrared light source assembly and the electronic device 1000 according to the embodiment of the present invention, through the cooperation of the visible light camera 200 and the iris recognition module 100, obtain iris color information through the visible light camera 200 before iris recognition, and according to the iris The color starts the infrared light source of the corresponding wavelength in the iris recognition module 100 to carry out iris recognition. For users of different races, the infrared light source of different working wavelengths is started, which increases the applicability of the iris recognition module on the one hand, and improves the Efficiency of iris recognition.
在某些实施方式中，电子装置1000包括手机、平板电脑、智能穿戴设备以及智能家居设备等。In some embodiments, the electronic device 1000 includes a mobile phone, a tablet computer, a smart wearable device, a smart home device, and the like.
请参阅图3，在某些实施方式中，步骤S10包括步骤：Referring to Fig. 3, in some embodiments, step S10 includes the steps of:
关闭或保持关闭红外识别模组；和turn off or keep off the infrared identification module; and
启动可见光摄像头。Start the visible light camera.
在某些实施方式中，关闭或保持关闭红外识别模组和启动可见光摄像头的步骤可以由处理器300实现。也即是说，处理器300用于关闭或保持关闭红外识别模组100并启动可见光摄像头200。In some implementations, the steps of turning off or keeping turning off the infrared recognition module and starting the visible light camera can be implemented by the processor 300 . That is to say, the processor 300 is used to turn off or keep off the infrared recognition module 100 and start the visible light camera 200 .
可以理解，由于红外识别模组100无法用于进行虹膜颜色信息的获取，并且红外设别模组100功耗较高。因此，在未确定较佳地工作波长对应的一组红外光源时，可先关闭或保持关闭红外识别模组100。例如，若虹膜识别模组100处于开启状态，则控制红外光源组件10或红外摄像头20中处于开启状态的部件关闭。若虹膜识别模组100处于关闭状态则保持关闭状态。It can be understood that the infrared identification module 100 cannot be used to acquire iris color information, and the infrared device identification module 100 consumes relatively high power consumption. Therefore, when a group of infrared light sources corresponding to a preferred operating wavelength is not determined, the infrared identification module 100 may be turned off or kept turned off. For example, if the iris recognition module 100 is in the on state, the components in the on state of the infrared light source assembly 10 or the infrared camera 20 are controlled to be turned off. If the iris recognition module 100 is in the off state, it will remain in the off state.
同时，启动可见光摄像头200以进行人脸图像的采集。At the same time, the visible light camera 200 is started to collect face images.
如此，可控制用于进行虹膜识别的各个组件有序地开启和关闭，同时也能节省红外光源持续开启的所带来的高功耗。In this way, various components used for iris recognition can be controlled to be turned on and off in an orderly manner, and at the same time, high power consumption caused by continuous turning on of the infrared light source can be saved.
在某些实施方式中，步骤S20包括以下步骤：In some embodiments, step S20 includes the following steps:
处理人脸图像以识别虹膜；和process images of faces to identify irises; and
处理人脸图像以得到虹膜颜色。Process face images to get iris color.
在某些实施方式中，处理人脸图像以识别虹膜和处理人脸图像以得到虹膜颜色的步骤可以由处理器300实现。或者说，处理器300用于处理人脸图像以识别虹膜并处理人脸图像以得到虹膜颜色。In some implementations, the steps of processing the face image to identify the iris and processing the face image to obtain the iris color can be implemented by the processor 300 . In other words, the processor 300 is used to process the face image to identify the iris and process the face image to obtain the iris color.
具体地，虹膜是一种环状薄膜，虹膜位于眼球中层，在巩膜和瞳孔之间。处理图像时，可通过特征点等信息确定人脸图像中的眼球位置，进而识别虹膜的颜色。当确定虹膜的颜色后，启动与虹膜颜色对应的工作波长的红外光光源以及红外摄像头进行虹膜图像的采集。Specifically, the iris is a ring-shaped membrane that is located in the middle layer of the eyeball, between the sclera and the pupil. When processing an image, the position of the eyeball in the face image can be determined through information such as feature points, and then the color of the iris can be identified. After the color of the iris is determined, an infrared light source with a working wavelength corresponding to the color of the iris and an infrared camera are started to collect iris images.
请参阅图4，在某些实施方式中，步骤S20包括以下步骤：Referring to Fig. 4, in some embodiments, step S20 includes the following steps:
根据人脸图像识别人脸肤色；和Identifying the skin color of a human face from an image of a human face; and
根据人脸肤色确定虹膜颜色。Determine the iris color based on the skin color of the face.
在某些实施方式中，根据人脸图像识别人脸肤色和根据人脸肤色确定虹膜颜色的步骤可以由处理器300实现。或者说，处理器300用于根据人脸图像识别人脸肤色并根据人脸肤色确定虹膜颜色。In some implementations, the steps of identifying the skin color of the face according to the face image and determining the iris color according to the skin color of the face can be implemented by the processor 300 . In other words, the processor 300 is configured to identify the skin color of the human face according to the human face image and determine the iris color according to the skin color of the human face.
具体地，由人脸肤色可以确定人种信息，确定的人种其虹膜颜色可确定并基本相同，因此，可以通过人脸肤色来确定虹膜颜色进而确定红外光源的工作波长。Specifically, the race information can be determined by the skin color of the human face, and the iris color of the determined race can be determined and is basically the same. Therefore, the iris color can be determined by the skin color of the human face to determine the working wavelength of the infrared light source.
肤色一般可包括白色，黄色及黑色等。肤色为白色时对应的瞳孔颜色通常是蓝绿色，而皮肤为黄色或黑色时对应的虹膜颜色通常为褐色或黑色。Skin color generally includes white, yellow and black. The pupil color for white skin is usually blue-green, and the iris color for yellow or black skin is usually brown or black.
请参阅图5，在这样的实施方式中，步骤S30包括以下步骤：Referring to FIG. 5, in such an embodiment, step S30 includes the following steps:
建立虹膜颜色与至少二红外光源的匹配关系；Establishing a matching relationship between iris color and at least two infrared light sources;
根据虹膜颜色启动与虹膜颜色匹配的红外光源。Depending on the color of the iris, an infrared light source that matches the color of the iris is activated.
在某些实施方式中，根据虹膜颜色启动与虹膜颜色匹配的红外光源的步骤可以由处理器300实现。或者说，处理器300用于根据虹膜颜色和匹配关系确定对应工作波长的一组红外光源并启动对应工作波长的一组红外光源。In some implementations, the step of activating the infrared light source matching the iris color according to the iris color can be implemented by the processor 300 . In other words, the processor 300 is configured to determine a group of infrared light sources corresponding to the working wavelength according to the iris color and the matching relationship, and activate the group of infrared light sources corresponding to the working wavelength.
电子装置1000出厂前可预置包括多个预存颜色和多个预存工作波长的匹配关系，每个预存颜色与一个预存工作波长对应，预存工作波长与红外光源的工作波长对应。Before leaving the factory, the electronic device 1000 can preset the matching relationship between multiple pre-stored colors and multiple pre-stored working wavelengths, each pre-stored color corresponds to a pre-stored working wavelength, and the pre-stored working wavelength corresponds to the working wavelength of the infrared light source.
颜色可以是颜色范围而非某一确定的颜色，如此，颜色适用范围更广泛。A color can be a range of colors rather than a certain color, so that the color applies to a wider range.
对应关系中的颜色可根据对虹膜颜色的统计确定，例如一般可包括蓝绿色，褐色及黑色等。预存的工作波长也即是对于预存的虹膜颜色进行虹膜识别效果较佳的红外光波长。红外光源组件10的红外光源的工作波长可选择与查询表中预存的工作波长相同。The colors in the corresponding relationship can be determined according to the statistics of iris colors, and generally include blue-green, brown, and black, for example. The pre-stored working wavelength is the infrared light wavelength with better iris recognition effect for the pre-stored iris color. The working wavelength of the infrared light source of the infrared light source assembly 10 can be chosen to be the same as the working wavelength pre-stored in the look-up table.
预存的工作波长也即是与预存的颜色相对应的进行虹膜识别效果较佳的红外光波长。The pre-stored working wavelength is the wavelength of infrared light corresponding to the pre-stored color and having a better iris recognition effect.
在操作中，当通过可见光摄像头获取虹膜的颜色或根据人脸肤色确定虹膜颜色后，查询该匹配关系，确定与所获取的虹膜的颜色相对应的预存颜色，进而根据预存颜色确定对应的预存工作波长，以选择相应工作波长的红外光源启动。In operation, after the color of the iris is acquired by the visible light camera or the color of the iris is determined according to the skin color of the face, the matching relationship is queried to determine the pre-stored color corresponding to the acquired iris color, and then the corresponding pre-stored work is determined according to the pre-stored color Wavelength, to select the infrared light source of the corresponding working wavelength to start.
在某些实施方式中，步骤S30还包括步骤：In some embodiments, step S30 also includes the steps of:
关闭可见光摄像头。Turn off the visible light camera.
在某些实施方式中，关闭可见光摄像头的步骤可以由处理器300实现。或者说，处理器300用于关闭可见光摄像头200。In some implementations, the step of turning off the visible light camera can be implemented by the processor 300 . In other words, the processor 300 is used to turn off the visible light camera 200 .
可以理解，可见光摄像头200的功耗较高，长时间持续开启，一来电能消耗较大，二来发热量较大，可能影响元件的寿命。并且可见光摄像头只用于采集颜色信息以获取虹膜颜色，在虹膜识别的过程中可以关闭。It can be understood that the power consumption of the visible light camera 200 is relatively high, and if it is continuously turned on for a long time, it will consume a lot of power and generate a lot of heat, which may affect the life of the components. And the visible light camera is only used to collect color information to obtain iris color, which can be turned off during the iris recognition process.
在某些实施方式中，虹膜识别模组100通常用于对当前使用电子装置1000的用户的身份进行识别，因此虹膜识别模组100通常前置，也即是设置在电子装置1000的前面板，例如设置于前面板顶端。可以理解地，虹膜识别模组100和可见光摄像头200设置在电子装置1000的壳体内并自前面板露出。In some embodiments, the iris recognition module 100 is usually used to identify the identity of the user currently using the electronic device 1000, so the iris recognition module 100 is usually front-mounted, that is, it is arranged on the front panel of the electronic device 1000, For example, it is set on the top of the front panel. Understandably, the iris recognition module 100 and the visible light camera 200 are disposed in the housing of the electronic device 1000 and exposed from the front panel.
在某些实施方式中，红外光源包括红外光源晶圆芯片、基板和封装体，基板用于为红外光源提供支撑。红外光源晶圆芯片以预定方式设置在基板上。可以理解，晶圆决定了红外光源的工作波长。红外光源组件100包括至少两组工作波长的红外光源，也即是说，两组红外光源中设置在基板上的红外光源晶圆芯片的工作波长。如此，可满足采集不同用户虹膜特征的需求。例如，在某些示例中，两组红外光源的晶圆的工作波长可分别包括780nm和850nm。其中，工作波长为780nm的红外光对于蓝绿色虹膜在虹膜识别过程中效果更佳。而850nm的红外光对于黑色虹膜在虹膜识别过程中效果更佳。In some embodiments, the infrared light source includes an infrared light source wafer chip, a substrate and a package body, and the substrate is used to provide support for the infrared light source. The infrared light source wafer chip is arranged on the substrate in a predetermined manner. It can be understood that the wafer determines the working wavelength of the infrared light source. The infrared light source assembly 100 includes at least two groups of infrared light sources with working wavelengths, that is to say, the working wavelengths of the infrared light source wafer chips disposed on the substrate in the two groups of infrared light sources. In this way, the requirement of collecting iris features of different users can be met. For example, in some examples, the working wavelengths of the wafers of the two groups of infrared light sources may respectively include 780 nm and 850 nm. Among them, the infrared light with a working wavelength of 780nm has a better effect on the blue-green iris in the iris recognition process. The 850nm infrared light is better for black irises in the iris recognition process.
封装体可以是胶体、树脂等材料，其上表面与晶圆上表面平齐，封装体还包括覆盖晶圆芯片上表面的透明盖板，以作为红外光的发射窗口，盖板可以采用一般的塑料、玻璃等具有良好透射性能的材料，也可采用能够对红外光进行散射的透镜，从而加大红外光的工作范围。The package body can be made of materials such as colloid, resin, etc., and its upper surface is flush with the upper surface of the wafer. The package body also includes a transparent cover plate covering the upper surface of the wafer chip to serve as an emission window for infrared light. The cover plate can use a general Materials with good transmission properties, such as plastic and glass, can also use lenses that can scatter infrared light, thereby increasing the working range of infrared light.
红外光源晶圆芯片经封装体封装后，形成红外光源，红外光源可通过板对板连接器与电子设备的主板进行连接，并由电子设备的主电源为其进行供电。After the infrared light source wafer chip is packaged by the package body, an infrared light source is formed. The infrared light source can be connected to the main board of the electronic device through a board-to-board connector, and is powered by the main power supply of the electronic device.
在一些示例中，每组红外光源可包括一个红外光源晶圆芯片，也即是每个封装体封装一个红外光源晶圆芯片。在另外一些示例中，多个红外光源晶圆芯片可共同封装于同一封装体内，也即是说，每组红外光源包括多个红外光源晶圆芯片。多个红外光源晶圆芯片的光轴可与红外摄像头20的光轴平行，也可与红外摄像头20的光轴呈一定的夹角。In some examples, each group of infrared light sources may include one infrared light source wafer chip, that is, each package encapsulates one infrared light source wafer chip. In some other examples, multiple infrared light source wafer chips can be packaged together in the same package, that is to say, each group of infrared light sources includes multiple infrared light source wafer chips. The optical axes of the plurality of infrared light source wafer chips can be parallel to the optical axis of the infrared camera 20 , or form a certain angle with the optical axis of the infrared camera 20 .
在某些实施方式中，基板呈环状、多个红外光源晶圆芯片沿基板的圆周方向分布。In some embodiments, the substrate is ring-shaped, and a plurality of infrared light source wafer chips are distributed along the circumferential direction of the substrate.
在这样的实施方式中，红外摄像头20设置在红外光源内侧。In such an embodiment, the infrared camera 20 is disposed inside the infrared light source.
具体地，基板可以是圆环状也可以是矩形环形等结构。一般地，为了用户的安全，红外光源的功率会在一定程度上进行限制，因此晶圆的有效工作距离通常为10-30厘米，在有效工作范围内红外摄像头20能较为清晰的获取虹膜图像。当红外摄像头20位于红外光源内侧时，呈圆环状分布的多个红外光源中的每个到红外摄像头20的传感器的距离基本相同，各个红外光源的工作距离也基本相同。Specifically, the substrate may be circular or rectangular. Generally, for the safety of users, the power of the infrared light source is limited to a certain extent, so the effective working distance of the wafer is usually 10-30 cm, and the infrared camera 20 can obtain relatively clear iris images within the effective working range. When the infrared camera 20 is located inside the infrared light source, the distance from each of the multiple infrared light sources distributed in a circular shape to the sensor of the infrared camera 20 is basically the same, and the working distance of each infrared light source is also basically the same.
矩形环状易于制造但仅能允许有限数量的晶圆芯片到红外摄像头20的传感器的距离基本相同，不同晶圆芯片的工作距离可能不同，因此操作中，在启动不同工作波长的红外光源时，用户可能会适当调节工作距离。Rectangular ring is easy to manufacture but can only allow a limited number of wafer chips to the sensor of the infrared camera 20. The user may adjust the working distance appropriately.
具体地，多组红外光源组件10可分别呈弧形，并共同组成环状。Specifically, multiple sets of infrared light source assemblies 10 may respectively be arc-shaped and form a ring together.
在某些实施方式中，红外光源晶圆芯片包括红外LED晶圆芯片。In some embodiments, the infrared light source wafer chip includes an infrared LED wafer chip.
LED晶圆芯片拥有较佳的热学性能、电性能、光学性能和机械性能，并且易于制造，价格低廉。LED wafer chips have better thermal properties, electrical properties, optical properties and mechanical properties, and are easy to manufacture and low in price.
在某些实施方式中，每一工作波长的红外光源的数目相同或不同。In certain embodiments, the number of infrared light sources for each operating wavelength is the same or different.
具体地，当工作波长较短时，例如780nm时，对蓝绿色的虹膜效果更佳，而对于蓝绿色的虹膜使用可见光的补光灯也能够成为有效光源，甚至使用波长更长的红外光也能够成为有效光源，而波长较长例如850nm的红外光对应的黑色虹膜仅能在当前波长或更长波长的照射下对虹膜成像，并且易受环境的影响。因此，波长越长的红外光源设置的数目越多，既能满足不同工作状况开启不同组红外光源也可满足多级功耗的需求。Specifically, when the working wavelength is shorter, such as 780nm, the effect on the blue-green iris is better, and the supplementary light using visible light can also be an effective light source for the blue-green iris, and even infrared light with a longer wavelength is also effective. Can become an effective light source, and the black iris corresponding to infrared light with a longer wavelength such as 850nm can only image the iris under the irradiation of the current wavelength or longer wavelength, and is easily affected by the environment. Therefore, the longer the wavelength of the infrared light source, the greater the number of settings, which can not only meet the needs of different working conditions to turn on different groups of infrared light sources, but also meet the requirements of multi-level power consumption.
在某些实施方式中，红外光源组件10还包括驱动元件，驱动元件用于选择性驱动至少一个红外光源晶圆芯片发光。In some embodiments, the infrared light source assembly 10 further includes a driving element for selectively driving at least one infrared light source wafer chip to emit light.
在这样的实施方式中，驱动元件包括开关和控制电路，其中开关用于连接每个红外光源晶圆芯片与对应驱动源，控制电路用于控制开关连通和关闭。In such an embodiment, the driving element includes a switch and a control circuit, wherein the switch is used to connect each infrared light source wafer chip with the corresponding driving source, and the control circuit is used to control the switch to be connected and closed.
可以理解，多组红外光源的工作波长不同，根据用户选择或使用情况选择开启部分组红外光源以发射红外光，通过控制开关的通断来控制相应的晶圆芯片与驱动源通断，可实现对红外光源的控制。开关的控制可通过处理器300实现。It can be understood that the working wavelengths of multiple sets of infrared light sources are different. According to the user's choice or usage, some sets of infrared light sources are selected to be turned on to emit infrared light, and the corresponding wafer chip and the driving source are controlled by controlling the on-off of the switch, which can realize Control of infrared light source. The control of the switch can be realized by the processor 300 .
