为了通过指纹识别来实现这样的安全访问,用户必须进行注册指纹程序,其中,与用户的指纹直接相关联的信息被登记之后,用户需要实际访问时在匹配程序中使用。在注册指纹期间,通常提示用户将手指置于指纹传感器上若干次,直到记录了完整的指纹或指纹的至少大部分为止。
然而,现有技术的注册指纹程序存在缺点。例如,为了采集到完整的指纹图像,用户需要不停的变换按压在显示屏上的手指的部位,进而使得指纹传感器能够采集到所述手指的不同位置的指纹信息,由此导致注册指纹的速度过慢,并降低了用户体验。
因此,如何提升注册指纹速度以及用户体验是本领域技术人员急需解决的问题。

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种电子设备。
例如,智能手机、笔记本电脑、平板电脑、游戏设备等便携式或移动计算设备,以及电子数据库、汽车、银行自动柜员机(Automated Teller Machine,ATM)等其他电子设备。但本申请实施例对此并不限定。
本申请实施例的技术方案可以用于生物特征识别技术。其中,生物特征识别技术包括但不限于指纹识别、掌纹识别、虹膜识别、人脸识别以及活体识别等识别技术。为了便于说明,下文以指纹识别技术为例进行说明。
本申请实施例的技术方案可以用于屏下指纹识别技术和屏内指纹识别技术。
屏下指纹识别技术是指将指纹识别模组安装在显示屏下方,从而实现在显示屏的显示区域内进行指纹识别操作,不需要在电子设备正面除显示区域外的区域设置指纹采集区域。具体地,指纹识别模组使用从电子设备的显示组件的顶面返回的光来进行指纹感应和其他感应操作。这种返回的光携带与显示组件的顶面接触的物体(例如手指)的信息,位于显示组件下方的指纹识别模组通过采集和检测这种返回的光以实现屏下指纹识别。其中,指纹识别模组的设计可以为通过恰当地配置用于采集和检测返回的光的光学元件来实现期望的光学成像。
相应的,屏内(In-display)指纹识别技术是指将指纹识别模组或者部分指纹识别模组安装在显示屏内部,从而实现在显示屏的显示区域内进行指纹识别操作,不需要在电子设备正面除显示区域外的区域设置指纹采集区域。
图1和图2示出了屏下指纹识别技术可以适用的电子设备100的示意图,其中图1为电子设备100的正面示意图,图2为图1所示的电子设备100的部分剖面结构示意图。
如图1和图2所示,电子设备100可以包括显示屏120和指纹识别模组140。
显示屏120可以为自发光显示屏,其采用具有自发光的显示单元作为显 示像素。比如显示屏120可以为有机发光二极管(Organic Light-Emitting Diode,OLED)显示屏或者微型发光二极管(Micro-LED)显示屏。在其他可替代实施例中,显示屏120也可以为液晶显示屏(Liquid Crystal Display,LCD)或者其他被动发光显示屏,本申请实施例对此不做限制。
此外,显示屏120还可以具体为触控显示屏,其不仅可以进行画面显示,还可以检测用户的触摸或者按压操作,从而为用户提供一个人机交互界面。比如,在一种实施例中,电子设备100可以包括触摸传感器,所述触摸传感器可以具体为触控面板(Touch Panel,TP),其可以设置在所述显示屏120表面,也可以部分集成或者整体集成到所述显示屏120内部,从而形成所述触控显示屏。
指纹识别模组140可以为光学指纹识别模组,比如光学指纹传感器。
具体来说,指纹识别模组140可以包括具有光学感应阵列的指纹传感器芯片(后面也称为光学指纹传感器)。其中,光学感应阵列包括多个光学感应单元,每个光学感应单元可以具体包括光探测器或者光电传感器。或者说,指纹识别模组140可以包括光探测器(Photo detector)阵列(或称为光电探测器阵列、光电传感器阵列),其包括多个呈阵列式分布的光探测器。
如图1所示,指纹识别模组140可以设置在所述显示屏120的下方的局部区域,从而使得指纹识别模组140的指纹采集区域(或检测区域)130至少部分位于所述显示屏120的显示区域102内。
当然,在其他可替代实施例中,指纹识别模组140也可以设置在其他位置,比如显示屏120的侧面或者电子设备100的边缘非透光区域。这种情况下,可以通过光路设计将显示屏120的至少部分显示区域的光信号导引到指纹识别模组140,从而使得所述指纹采集区域130实际上位于所述显示屏120的显示区域内。
在本申请的一些实施例中,指纹识别模组140可以仅包括一个指纹传感器芯片,此时指纹识别模组140的指纹采集区域130的面积较小且位置固定,因此用户在进行指纹输入时需要将手指按压到所述指纹采集区域130的特定位置,否则指纹识别模组140可能无法采集到指纹图像而造成用户体验不佳。
在本申请的另一些实施例中,指纹识别模组140可以具体包括多个指纹传感器芯片;所述多个指纹传感器芯片可以通过拼接方式并排设置在所述显示屏120的下方,且所述多个指纹传感器芯片的感应区域共同构成所述指纹 识别模组140的指纹采集区域130。也即是说,所述指纹识别模组140的指纹采集区域130可以包括多个子区域,每个子区域分别对应于其中一个指纹传感器芯片的感应区域,从而将所述光学指纹模组130的指纹采集区域130可以扩展到所述显示屏的下半部分的主要区域,即扩展到手指惯常按压区域,从而实现盲按式指纹输入操作。可替代地,当所述指纹传感器芯片数量足够时,所述指纹检测区域130还可以扩展到半个显示区域甚至整个显示区域,从而实现半屏或者全屏指纹检测。
图3是本申请实施例的引导用户注册指纹的方法200的示意性流程图。应理解,所述方法200可以由图1或图2所示的电子设备执行,也可以由包括显示屏和指纹传感器芯片的任一设备执行,本申请对此不做限定。为了便于理解,下面以所述方法由电子设备执行为例进行说明。
如图3所示,所述方法200可以包括:
S210,电子设备根据所述至少一个指纹传感器芯片的第一指纹传感器芯片所在的第一指纹采集区域,在所述显示屏的显示区域显示第一图像,所述第一图像用于指示用户进行注册指纹时的按压位置。
S210,所述电子设备根据所述第一指纹采集区域变换所述第一图像的位置,以便所述第一指纹传感器芯片采集所述用户的手指的不同位置的指纹信息。
具体而言,所述电子设备基于所述第一指纹采集区域的位置显示所述第一图像后,用户将手指按压在所述第一图像在所述显示区域内的位置上,由此实现第一次指纹输入操作。所述电子设备基于所述第一指纹采集区域的位置变换所述第一图像的显示位置后,用户将手指再次按压在所述第一图像在所述显示区域内的位置上,由此实现第二次指纹输入操作。由于所述第一指纹采集区域在显示区域的位置固定不变,通过变换所述第一图像的位置引导所述用户在所述显示区域内的不同位置进行按压,可以使得用户每次按压显示屏时所述第一指纹传感器芯片采集到的指纹信息可以包括所述用户的手指的不同位置的指纹信息,进而,避免了用户在注册指纹过程中需要不停的变换按压在显示屏上的手指的部位,能够有效提高注册指纹的速度以及用户体验。
在本申请的一些实施例中,所述显示屏被按压且按压力大于或等于预设阈值时,所述电子设备基于所述第一指纹采集区域显示所述第一图像,并在 用户输入指纹后,变换所述第一图像的显示位置,进而实现对所述用户的手指的不同位置的指纹信息的采集。
应理解,本申请实施例对所述第一指纹传感器不做具体限定。
例如,所述第一指纹传感器芯片可以是所述至少一个指纹传感器芯片中特定的指纹传感器芯片。此时,由于所述第一指纹传感器芯片所在的第一指纹采集区域在显示区域内的位置是固定的,因此在一个注册指纹过程中用于首次显示所述第一图像的位置可以是预设位置。例如,所述第一图像在一个注册指纹过程中首次显示的位置可以是所述第一指纹采集区域的左侧区域、右侧区域、顶部区域或者底部区域等任一区域。
又例如,所述第一指纹传感器芯片可以是用户首次按压的指纹传感器芯片或者首次采集到指纹信息的指纹传感器芯片。具体而言,所述显示屏被所述用户按压时,所述电子设备根据按压位置确定第一指纹传感器,并基于所述第一传感器所在的第一指纹采集区域在所述显示区域内的位置确定目标位置;然后,所述电子设备在在所述目标位置上显示所述第一图像。
在上述S220中,所述电子设备可以根据所述第一指纹采集区域,按照预设顺序变换所述第一图像的位置。例如,所述电子设备可以根据所述第一指纹采集区域啊,按照逆时针方向变换所述第一图像的显示位置。又例如,所述电子设备可以按照顺时针方向变换所述第一图像的显示位置。
在本申请的一些实施例中,所述至少一个指纹传感器芯片仅包括所述第一指纹传感器芯片。此时所述电子设备可以按照以下预设顺序变换所述第一图像的位置:
所述第一指纹采集区域的左侧区域、右侧区域、顶部区域和底部区域。
图4至图7是仅包括一个指纹传感器芯片的电子设备引导用户注册指纹的过程的示意图。所述电子设备的指纹采集区域仅包括所述第一指纹传感器所在的第一指纹采集区域131。
在注册指纹的过程中,如图4所示,所述电子设备首先在第一指纹传感器芯片所在的第一指纹采集区域131的右侧区域显示所述第一图像160,以引导用户按压所述第一指纹采集区域131的右侧区域;此时所述第一指纹传感器芯片能够采集到所述用户的手指170的左侧指纹信息。然后,如图5所示,所述电子设备在所述第一指纹采集区域131的左侧区域重新显示所述第一图像160,以引导所述用户按压所述第一指纹采集区域131的左侧区域; 此时所述第一指纹传感器芯片能够采集到所述用户的手指170的右侧指纹信息。进一步地,如图6所示,所述电子设备在所述第一指纹采集区域131的顶部区域重新显示所述第一图像160,以引导所述用户按压所述第一指纹采集区域131的顶部区域;此时所述第一指纹传感器芯片能够采集到所述用户的手指170的底部指纹信息。最后,如图7所示,所述电子设备在所述第一指纹采集区域131的底部区域重新显示所述第一图像160,以引导所述用户按压所述第一指纹采集区域131的底部区域;此时所述第一指纹传感器芯片能够采集到所述用户的手指170的顶部指纹信息。
通过对所述第一指纹传感器芯片在上述4次采集过程中采集到的指纹信息进行拼接,所述电子设备可以得到所述用户的手指的完整的信息。
应理解,图4至图7仅为本申请的示例,不应理解为对本申请的限制。
例如,在其他可替代实施例中,所述电子设备对所述第一图像的显示位置的变换次数可以少于或多于3次。举例来说,所述电子设备可以按照以下顺序变换所述第一图像的显示位置:所述第一指纹采集区域的左侧区域、左上角区域、右侧区域、右上角区域、顶部区域、底部区域、左下角区域以及右下角区域。或者,所述电子设备可以仅在所述第一指纹采集区域的左侧区域和右侧区域之间变换。
又例如,所述电子设备可以在所述第一指纹采集区域的左侧区域、右侧区域、顶部区域和底部区域中按照任一预定顺序变换所述第一图像的显示位置。
在本申请的另一些实施例中,所述电子设备可以包括多个指纹传感器芯片,所述多个指纹传感器芯片可以通过并排设置,拼接成一个指纹传感器芯片组件。此时所述电子设备可以按照以下预设顺序变换所述第一图像的位置:
所述至少一个指纹传感器芯片中的第二指纹传感器所在的第二指纹采集区域和所述第一指纹采集区域的中间区域、所述第一指纹采集区域的中间区域、所述第一指纹采集区域的顶部区域和所述第一指纹采集区域的底部区域。
图8至图11是包括多个指纹传感器芯片的电子设备引导用户注册指纹的过程的示意图。所述电子设备的指纹采集区域可以包括第一指纹传感器芯片所在的第一指纹采集区域131、第二指纹传感器芯片所在的第二指纹采集区域132、第三指纹传感器芯片所在的第三指纹采集区域133以及第四指纹 传感器芯片所在的第四指纹采集区域134。
在注册指纹的过程中,如图8所示,所述电子设备首先在所述第一指纹采集区域131和所述第二指纹采集区域132的中间区域显示所述第一图像160,以引导用户按压所述第一指纹采集区域131和所述第二指纹采集区域的中间区域;此时所述第一指纹传感器芯片能够采集到所述用户的手指170的右侧指纹信息,所述第二指纹传感器芯片能够采集到所述手指170的左侧指纹信息。然后,如图9所示,所述电子设备在所述第一指纹采集区域131的中间区域重新显示所述第一图像160,以引导所述用户按压所述第一指纹采集区域131的中间区域;此时所述第一指纹传感器能够采集到所述用户的手指170的中间位置的指纹信息。进一步地,如图10所示,所述电子设备在所述第一指纹采集区域131的顶部区域重新显示所述第一图像160,以引导所述用户按压所述第一指纹采集区域131的顶部区域;此时所述第一指纹传感器芯片能够采集到所述用户的手指170的底部指纹信息。最后,如图11所示,所述电子设备在所述第一指纹采集区域131的底部区域重新显示所述第一图像160,以引导所述用户按压所述第一指纹采集区域131的底部区域;此时所述第一指纹传感器芯片能够采集到所述用户的手指170的顶部指纹信息。
通过对所述第一指纹传感器芯片和所述第二指纹传感器芯片在第一次采集过程中采集到的指纹信息,以及所述第一指纹传感器芯片在剩余的3次采集过程中采集到的指纹信息进行拼接,所述电子设备可以得到所述用户的手指的完整的信息。
类似地,图8至图11也仅为本申请的示例,不应理解为对本身的限制。
例如,在其他可替代实施例中,所述电子设备在图8所示的位置显示所述第一图像后,后续可以在所述第二指纹采集区域的中间位置、顶部区域以及底部区域之间变换。又例如,所述电子设备对所述第一图像的显示位置的变换次数可以少于或多于3次。
又例如,所述电子设备可以在所述至少一个指纹传感器芯片中的第二指纹传感器所在的第二指纹采集区域和所述第一指纹采集区域的中间区域、所述第一指纹采集区域的中间区域、所述第一指纹采集区域的顶部区域和所述第一指纹采集区域的底部区域中按照任一预定顺序变换所述第一图像的显示位置。
应理解,本申请实施例对所述第一图像160的样式不做具体限定。例如,第一图像160可以是标识图案或提示框。所述标识图案可以是指纹图片或是其他类型的图像。所述提示框的形状可以圆形或、长方形或长方形等规则形状,所述提示框的形状也可以是非规则形状。如图4至图11所示,所述提示框可以为方形提示框。
还应理解,所述第一图像160在显示屏的显示区域内的面积可以大于或小于甚至等于所述第一指纹采集区域131在所述显示区域内的面积。此外,所述第一图像160可以和所述第一指纹采集区域131部分重叠,也可以完全重叠。本申请实施例对此不做限制。
还应理解,所述电子设备在显示区域内多次显示所述第一图像160时,在不同的显示位置,所述第一图像160在所述显示区域内可以部分重叠或不重叠,本申请对此不做具体限定。
在本申请的一些实施例中,所述电子设备的显示屏可以包括发光层,所述发光层可以包括指纹照明区域。所述指纹采集区域用于照亮所述电子设备的指纹传感器芯片的指纹采集区域。例如,所述指纹采集区域被所述用户按压时,所述指纹照明区域内的发光像素照亮可以至少照亮所述第一指纹采集区域131。结合附图来说,所述电子设备在图8所示的位置显示所述第一图像160时,所述指纹照亮区域可以同时照亮所述第一指纹采集区域131和所述第二指纹采集区域132。当然,所述电子设备也可以照亮所有指纹传感器芯片所在的指纹采集区域,本身实施例对此不做具体限定。
具体而言,发光像素所发出的光束在手指的表面发生反射形成反射光或者经过手指的内部散射后而形成散射光,在相关专利申请中,为便于描述,上述反射光和散射光统称为反射光。由于指纹的嵴(ridge)与峪(vally)对于光的反射能力不同,因此,来自指纹嵴的反射光和来自指纹峪的发生过具有不同的光强,反射光经过显示屏后,被指纹传感器芯片所接收并转换为相应的电信号,即指纹信息。
换句话说,在用户注册指纹的过程中,用户根据所述第一图像160在显示屏上的160的显示位置按压所述显示屏,屏幕亮起与所述第一图像160产生交集的指纹采集区域对应的发光像素(也称为光斑),所述电子设备的指纹传感器芯片通过接收指纹纹路反射回来的反射光采集用户的指纹信息,。
当然,在其他替代方案中,指纹传感器芯片也可以采用内置光源或者外 置光源来提供用于进行指纹检测识别的光信号。在这种情况下,指纹传感器芯片不仅可以适用于如OLED显示屏等自发光显示屏,还可以适用于非自发光显示屏,比如液晶显示屏或者其他的被动发光显示屏。
在本申请的一些实施例中,所述方法200还可包括:
所述电子设备在所述电子设备的显示屏的显示区域显示第二图像,所述第二图像用于显示所述第一图像所述在显示区域被用户按压时采集的指纹信息。即所述用户按压所述显示屏时,所述电子设备可同步显示指纹采集结果,所述采集结果可以为所述电子设备是否变换所述第一图像的显示位置提供参考。例如,如图4所示,假设所述第一图像的当前显示位置为所述第一指纹采集区域131的右侧区域,此时所述第二图像用于显示所述用户的手指170的左侧指纹信息,如果所述第二图像显示的所述手指170的左侧指纹信息不完整时,所述用户可以再次按压所述显示屏,直至所述第二图像能够完整的显示所述手指170的左侧指纹信息。进一步的,所述电子设备在图5所示的显示位置上显示所述第一图像160时,所述第二图像可以仅用于显示所述手指170的右侧指纹信息,也可以用于同时显示所述右侧指纹信息和所述电子设备之前采集的左侧指纹信息,本申请对此不做具体限定。
在本申请的一些实施例中,所述方法200还可以包括:
所述第二图像为整个手指的指纹图像时,所述电子设备停止显示所述第一图像。即所述电子设备确定已完成注册指纹过程中的指纹采集操作,此时所述电子设备可以将拼接后得到的完整指纹图像当做指纹模板存储在所述电子设备的存储器中,以便于在后续的识别指纹过程中使用所述指纹模板。
