本实用新型一实施方式提出一种实现面部信息采集以进行身份识别的智能终端,该智能终端根据周围环境的光强检测结果,来控制是否开启智能终端的补光功能,从而实现环境较暗时也能采集到清晰的面部图像,进而进行身份识别。
该智能终端例如但不局限为消费性电子产品、家居式电子产品、车载式电子产品、金融终端产品等合适类型的电子产品。其中,消费性电子产品如为手机、平板电脑、笔记本电脑、桌面显示器、电脑一体机等。家居式电子产品如为智能门锁、电视、冰箱、穿戴式设备等。车载式电子产品如为车载导航仪、车载DVD等。金融终端产品如为ATM机、自助办理业务的终端等。
该智能终端以移动终端为例,参照图1,图1是本实用新型一实施方式的智能终端的结构示意图。该移动终端100包括显示装置101以及位于显示装置101周边、且位于移动终端的顶部、底部或侧边的摄像头102、补光灯103、光线传感器104。当然,移动终端正面还可以设置其他的组件,例如麦克风、扬声器等等。而且该组件还可以设置于显示装置101的显示区域内。
由于移动终端正面的最外层为保护盖板,因此该保护盖板上需要为设置于移动终端正面的组件的安装预留相应的位置,例如保护盖板上的开孔或开口。然,可变更地,该设置于移动终端正面的组件可位于保护盖板下方,或者位于保护盖板内侧开设的盲孔或盲槽内。如此免去了保护盖板的开孔或开口结构,不但增加了移动终端的防水效果,还降低了生产成本,另外还提升了移动终端的美观。
参照图2,图2是本实用新型一实施方式的智能终端的功能模块示意图。该移动终端100进一步包括图像传感模块110、补光装置120、环境光传感模块130、处理模块140。
其中,环境光传感模块130包括光线传感器104以及相应的环境光感测电路。该光线传感器104设置于智能终端正面,用于在智能终端需要进行面部识别时,采集智能终端的周围环境的光照强度。当智能终端的周围环境较亮时,采集到的光照强度则较强;当智能终端的周围环境较暗时,采集到的光照强度则较弱。环境光感测电路与光线传感器104电连接,用于将光线传感器104感测到的光信号转换为相应的电信号,并输出。然,可变更地,该智能终端的周围环境的光照强度还可以采用其他的传感设备进行采集,例如智能终端正面设置的摄像头、设置于智能终端屏幕内的感光装置。
图像传感模块110设置于智能终端正面,用于采集智能终端前方物体的面部图像。图像传感模块110例如包括摄像头以及相应的图像处理电路,该摄像头例如CCD、CMOS图像传感器。该图像传感模块110不需要额外设置,例如现有智能终端正面设置前置摄像头时,则可以利用该前置摄像头进行面部图像的采集。当然,也可以根据拍摄需求设置对应拍摄参数的图像传感模块,专用于面部识别时进行面部图像的采集。图像处理电路用于设置相应的拍摄参数,以控制摄像头进行图像采集;同时,还用于将摄像头采集到的图像进行初步处理,例如滤波、去躁、压缩等等。
补光装置120用于在智能终端周围环境较暗时进行补光,以便于图像传感模块110的图像采集。补光装置120例如包括多个LED或其他发光元件。而且该发光元件的亮度、颜色以及色温等补光参数可以根据需要进行控制。本实施方式中,通过控制LED的亮度、颜色以及色温中的一个或几个补光参数,将使得补光装置发出的光信号更加柔和,从而在进行面部图像采集时,用户不至于感觉太刺眼,提升了用户体验。
处理模块140用于:在智能终端需要进行面部识别时,从所述环境光传感模块130读取当前环境光强度,并当前环境光强度与预设阈值进行比较;当当前环境光强度小于或等于预设阈值时,提供第一驱动信号给所述补光装置120,驱动智能终端的补光装置120开启,以进行正面补光;提供第二驱动信号给所述图像传感模块110,驱动所述图像传感模块110采集智能终端前方物体的面部图像。
本实用新型实施方式中,在需要进行面部识别时,根据智能终端周围环境的明暗来控制智能终端的补光;若智能终端周围环境较暗,则控制智能终端进行补光,从而使得智能终端能采集到清晰的面部图像,提高面部识别效果,提升用户体验。
进一步地,上述第一驱动信号和第二驱动信号同时产生并对应提供给补光装置120和图像传感模块110。即控制智能终端进行正面补光的同时,控制智能终端正面的图像传感模块进行面部图像的采集。需要说明的是,这里说的同时,并不要求时间上的严格 一致,也可以有时间上的先后顺序。只是时间相差较短,基本可以忽略不计,给人们的感觉上两者是同时进行。
进一步地,在某些实施方式中,通过预设一个临界值,即预设阈值,该预设阈值例如可以存储在一存储器中。若环境光强度大于该预设阈值,则表示智能终端在当前环境下能采集到清晰的面部图像,以实现面部识别;若环境光强度小于或等于预设阈值,则表示智能终端在当前环境下无法采集到清晰的面部图像,造成面部识别失败。因此,处理模块140通过比较环境光传感模块130输出的电信号与预设电信号进行比较,并根据比较结果控制是否产生第一驱动信号。具体地,当当前环境光强度大于预设阈值时,不产生第一驱动信号,直接产生第二驱动信号控制智能终端正面的图像传感模块110采集智能终端前方物体的面部图像。当当前环境光强度小于或等于预设阈值时,控制智能终端的补光装置120开启,以对智能终端进行正面补光。同时再产生第二驱动信号,以控制图像传感模块110采集智能终端前方物体的面部图像。该处理模块140例如包括比较电路、第二驱动信号产生电路以及其他的逻辑控制电路等等。
在某些实施方式中,该补光装置120设置于智能终端正面,例如包括智能终端的显示屏121、位于智能终端顶部的补光光源122。该补光光源122为额外设置且专用于补光的部件,例如设置在智能终端正面的补光灯103,该补光灯103可为柔光灯。在进行面部识别时,根据实际需要来选择使用其中显示屏121和补光光源122中的一个进行补光,或者两者结合进行补光。例如,通过补光光源122进行补光时,处理模块140用于:当当前环境光强度小于或等于预设阈值时,控制补光光源开启,以进行正面补光。
通过智能终端的显示屏121进行补光时,则利用现有结构即可实现补光,节省了成本。通过补光光源122进行补光时,虽然增加了成本,但是既不影响其他组件(例如显示屏)的正常工作,而且还可实现更好的补光效果。
进一步地,补光装置120例如包括多个LED或其他发光元件。而且该发光元件的亮度、颜色以及色温等补光参数可以根据需要进行控制。本实施方式中,通过控制LED的亮度、颜色以及色温中的一个或几个补光参数,将使得补光装置120发出的光信号更加柔和,从而在进行面部图像采集时,用户不至于感觉太刺眼,提升了用户体验。例如,上述处理模块140在控制补光光源122开启的同时,还用于控制补光光源122的亮度、颜色以及色温中的一个或几个参数,以使得补光光源122发出的光信号更加柔和。
在某些实施方式中,处理模块140进一步用于:当当前环境光强度小于或等于预设阈值时,调节显示屏121至最大亮度,以进行正面补光。
若智能终端通过显示屏121进行智能终端的正面补光,则在当前环境光强度小于或等于预设阈值时,调节显示屏121至最大亮度,以进行正面补光。显示屏亮度的调节,可以逐次进行调节,以免亮度骤增对用户造成不适。
进一步地,处理模块140还用于,若当前环境光强度与显示屏121的最大亮度之和仍然小于或等于预设阈值,则控制智能终端正面的补光光源122开启,以使所述补光光源122与所述显示屏121一起进行正面补光。
由于显示屏本身的发光能力有限,若显示屏121的亮度无法达到补光要求,则控制智能终端正面顶端的补光光源122开启,以使补光光源122与显示屏121一起进行正面补光。因此,本实施方式中,先调节显示屏121至最大亮度,同时采集当前环境光强度,若当前环境光强度仍然小于或等于预设阈值,则表示显示屏121的补光无法达到补光要求,此时控制智能终端正面顶端的补光光源122开启。若当前环境光强度大于预设阈值,则表示显示屏121的亮度能够达到补光要求,因此仅通过显示屏121的亮度进行补光即可。
在某些实施方式中,上述处理模块140进一步用于:判断智能终端的当前工作状态,根据智能终端的当前工作状态,确定是否需要进行面部识别。
当前工作状态按照显示屏的显示状态来分,例如包括息屏状态、亮屏未解锁状态、亮屏已解锁状态三种。其中息屏状态是指显示屏未被点亮而处于熄灭状态。亮屏未解锁状态是指显示屏被点亮,但显示屏上显示未解锁界面。该状态下,智能终端未被解锁,无法进入智能终端的主页面。亮屏已解锁状态是指显示屏被点亮,并根据具体的操作显示相应的界面。该状态下智能终端已经解锁,使用者可以正常使用该智能终端。
具体地,当智能终端处于息屏状态时,使用者随时可能会使用该智能终端,因此为了能快速响应使用者的操作,该智能终端上的某些传感器仍然处于工作状态,以监测智能终端的使用情况,判断是否存在屏幕唤醒操作。例如,触摸传感器、重力传感器、距离传感器等等。屏幕唤醒操作包括拿起智能终端、触摸智能终端的显示屏、物体靠近设备正面预设范围、按压智能终端的功能按键中的一种或几种。可以理解的是,该智能终端的屏幕唤醒操作可根据使用者的需要而灵活设置。
进一步地,智能终端还包括触摸传感模块150,用于检测显示屏121上是否有物体触摸。该触摸传感模块150可以独立设置,也可以与显示屏121集成为触摸显示屏。本实用新型实施方式中,在智能终端处于息屏状态时,控制智能终端的触摸传感模块150执行触摸检测,对显示屏121上的触摸动作(例如普通触摸操作、按压操作、滑动操作) 进行检测及响应。当智能终端处于息屏状态时,该触摸传感模块150将以第一扫描频率(较低功耗状态)进行触摸检测。当检测到物体触摸显示屏,则确定需要进行面部识别。当智能终端处于亮屏未解锁状态或亮屏已解锁状态时,触摸传感模块150再以第二扫描频率(较高功耗状态或正常功耗状态)进行触摸检测,从而降低智能终端息屏状态时的功耗。其中第一扫描频率小于第二扫描频率。当然,可变更地,该触摸传感模块150也可以一直以正常功耗状态进行触摸检测。
当智能终端处于亮屏未解锁状态时,这种情况下使用者随时可能使用该智能终端,因此确定需要进行面部识别。
当智能终端处于亮屏已解锁状态时,则要进一步判断当前是否存在应用程序向操作系统发起的身份验证请求,例如支付应用程序发起用于移动支付的身份验证请求。若存在身份验证请求,则确定需要进行面部识别,否则智能终端进行正常的操作。
在本说明书的描述中,参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本实用新型的至少一个实施方式或示例中。在本说明书中,对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且,描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管上面已经示出和描述了本实用新型的实施方式,可以理解的是,上述实施方式是示例性的,不能理解为对本实用新型的限制,本领域的普通技术人员在本实用新型的范围内可以对上述实施方式进行变化、修改、替换和变型。
