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。In the
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
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
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
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 the security of users' personal information, and obtain the authority to obtain corresponding information and operations through corresponding verification methods. Authentication methods usually include character passwords, pattern passwords, and other text-pattern passwords. However, such passwords are usually easy to crack, thus rendering 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 recognition. 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 detrimental 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 user's identity by comparing the similarity between iris image features. The 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 process 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. Accordingly, 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. The response efficiency and effect of different colors of irises to the same working wavelength are different. For example, iris images can be obtained by using visible light with a wavelength of 700 nm 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 set in the iris recognition module, a compromise is usually required, which is not 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
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
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
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 and the
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
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 the infrared identification module off; and
启动可见光摄像头。Activate 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 embodiments, the steps of turning off or keeping off the infrared identification module and activating the visible light camera may be implemented by the
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, because the
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
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, each component used for iris recognition can be controlled to be turned on and off in an orderly manner, and at the same time, the high power consumption caused by the 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:

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 an annular membrane that is located in the middle layer of the eyeball, between the sclera and the pupil. When processing images, the position of the eyeballs 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, the infrared light source of the working wavelength corresponding to the color of the iris and the infrared camera are started to collect the iris image.
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Identify the skin color of the face from the face image; and
根据人脸肤色确定虹膜颜色。Determines 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 embodiments, the steps of recognizing the skin color of the face according to the face image and determining the color of the iris according to the skin color of the face may be implemented by the
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 ethnicity information can be determined from the skin color of the face, and the iris color of the determined ethnicity can be determined and basically the same. Therefore, the iris color can be determined by the skin color of the 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 can generally include white, yellow and black. The color of the pupil is usually blue-green when the skin is white, and the color of the iris is usually brown or black when the skin is yellow 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 the 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。Activates an IR light source that matches the color of the iris based on the color of the iris.
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 embodiments, the step of activating the infrared light source matching the color of the iris according to the color of the iris may be implemented by the
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。The
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。Colors can be a range of colors rather than a certain color, so the color can be used in 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 statistics on the colors of the iris, and generally include blue-green, brown, and black, for example. The pre-stored working wavelength is also the wavelength of infrared light with a better iris recognition effect for the pre-stored iris color. The working wavelength of the infrared light source of the infrared
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 also the infrared light wavelength corresponding to the pre-stored color with 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, when the color of the iris is obtained 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 color of the iris, and then the corresponding pre-stored work is determined according to the pre-stored color. wavelength to start with an infrared light source that selects the corresponding working wavelength.

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 embodiments, the step of turning off the visible light camera may be implemented by the
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
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
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, 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

Materials with good transmission properties such as plastics 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 encapsulated 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 the 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 body encapsulates one infrared light source wafer chip.

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 annular, 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
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 a circular ring shape or a rectangular ring shape or the like. Generally, for the safety of users, the power of the infrared light source will be limited to a certain extent, so the effective working distance of the wafer is usually 10-30 cm, and the
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。The rectangular ring is easy to manufacture but can only allow a limited number of wafer chips to have substantially the same distance from the sensor of the
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, the plurality of groups of infrared

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 short, such as 780nm, the effect on the blue-green iris is better, and for the blue-green iris, a visible light fill light can also become an effective light source, and even infrared light with a longer wavelength is used. It can become an effective light source, while the black iris corresponding to infrared light with a longer wavelength, such as 850 nm, can only image the iris under the illumination of the current wavelength or longer wavelength, and is easily affected by the environment. Therefore, the number of infrared light sources with longer wavelengths is increased, which can not only meet the requirements of turning on different groups of infrared light sources under different working conditions, but also meet the requirements of multi-level power consumption.
