处理人脸图像以获取人脸位置信息;和
根据人脸位置信息启动人脸落入对应照明范围的红外光源12并关闭或保持关闭其他红外光源12。
也即是说,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100实现,其中,步骤S32、S34和S36可以由处理器30实现。
本发明实施方式的控制方法和电子装置100根据人脸位置信息启动红外光源12,从而使得人脸落入启动的红外光源12的照明范围,进而有助于电子装置100获取清晰的虹膜图像。
在某些实施方式中,红外光源12是指能够产生红外辐射(红外光)的光源,红外辐射是波长大于红色光波长的一定范围的电磁辐射。
在某些实施方式中,至少两个照明范围不同的红外光源12可分别设置在电子装置100的上下左右等不同位置,由于红外光源12的照明范围限制,使得红外光源12能够覆盖的照明范围不同,例如在红外光源12处于电子装置100的左边时,红外光源12对于电子装置100左前方的照明效果较佳,对电子装置100右前方的照明效果不佳甚至不能覆盖。
在某些实施方式中,人脸位置信息是指人脸相对于电子装置100的位置,如在人脸处于电子装置100左前方时,人脸位置信息为左前方,对应照明范围的红外光源12可以是处于电子装置100的左边的红外光源12,因此可以启动处于电子装置100的左 边的红外光源12以使得红外光源12为人脸提供红外光,另外,可以关闭或保持关闭其他红外光源12以避免对电子装置100造成不必要的电量消耗和多个红外光源12一起工作导致的严重发热。需要说明的是,由于除了对应照明范围的红外光源12外的其他红外光源12可能处于启动状态或者关闭状态,因此,关闭或保持关闭其他红外光源12可以是指关闭其他红外光源12中处于启动状态的红外光源12和保持关闭其他红外光源12中处于关闭状态的红外光源12。
在某些实施方式中,人脸位置信息包括人眼位置信息、鼻子位置信息、耳朵位置信息等,即可以通过人眼、鼻子、耳朵等部位的位置信息来确定人脸位置信息。
在某些实施方式中,电子装置100包括手机、笔记本电脑、平板电脑、智能手表或智能眼镜。在本发明实施方式中,电子装置100是手机。
请参阅图3,在某些实施方式中,摄像头20包括红外摄像头22,电子装置100包括虹膜识别模组40,虹膜识别模组40包括红外光源组件10和红外摄像头22。
如此,红外摄像头22与红外光源组件10可以协同工作以实现虹膜图像的成像。
具体地,利用红外光源组件10中的红外光源12对人眼发射红外光以使得虹膜的细节信息(如斑点、细丝、冠状、条纹、隐窝等)变得明显和清晰,再利用红外摄像头22对虹膜进行成像以获得虹膜图像。
请参阅图4,在某些实施方式中,步骤S32包括以下步骤:
S322:关闭或保持关闭所有红外光源12;和
S324:控制红外摄像头22采集人脸图像。
请再次参阅图3,在某些实施方式中,处理器30用于:
关闭或保持关闭所有红外光源12;和
控制红外摄像头22采集人脸图像。
也即是说,步骤S322和S324可以由处理器30实现。
如此,可以利用红外摄像头22采集人脸图像。
可以理解,在本发明实施方式中,人脸图像用于获取人脸位置信息,因而对于人脸图像的质量(如色彩、分辨率等)要求不高,因此可以利用红外摄像头22采集人脸图像,从而利用红外摄像头22采集的人脸图像来获取人脸位置信息。此外,在红外摄像头22采集人脸图像时,可以关闭和保持关闭所有红外光源12以避免对电子装置100造成不必要的电量消耗。
请参阅图5,在某些实施方式中,步骤S32包括以下步骤:
S326:启动至少任一红外光源12并关闭或保持关闭其他红外光源12;和
S328:控制红外摄像头22采集人脸图像。
请再次参阅图3,在某些实施方式中,处理器30用于:
启动至少任一红外光源12并关闭或保持关闭其他红外光源12;和
控制红外摄像头22采集人脸图像。
也即是说,步骤S326和S328可以由处理器30实现。
如此,可以启动红外光源12以辅助红外摄像头22采集人脸图像。
在某些实施方式中,例如由于红外摄像头22的配置比较低使得红外摄像头22的红外光采集能力不足,从而导致红外摄像头22无法单独获取人脸图像,因此,可以启动至少任一红外光源12以辅助红外摄像头22获取人脸图像,关闭或关闭其他红外光源12以减少对电子装置100的电量消耗。需要说明的是,启动至少任一红外光源12是指启动任意一个红外光源12,数量至少是一个。具体地,可以先启动任意一个红外光源12,并控制红外摄像头22采集人脸图像,判断红外摄像头22是否采集人脸图像成功,若采集人脸图像成功,则可以执行后续控制方法,例如步骤S340:处理人脸图像以获取人脸位置信息;若采集人脸图像不成功,则可以再多启动一个红外光源12或关闭现在启动的红外光源12再重新启动另一个红外光源12,然后控制红外摄像头22采集人脸图像直到采集人脸图像成功。
请参阅图6,在某些实施方式中,摄像头20包括可见光摄像头24,电子装置100包括虹膜识别模组40,虹膜识别模组40包括红外光源组件10和红外摄像头22。
如此,可以利用可见光摄像头24采集人脸图像。
可以理解,电子装置100为了实现功能的多样性,电子装置100的摄像头20可以包括可见光摄像头24以利用可见光摄像头24获得彩色图像。由于可见光摄像头24的相关技术(如控制方法或图像数据处理方法等)比较成熟,利用可见光摄像头24可以快速地获得人脸图像。
请参阅图7,在某些实施方式中,电子装置100包括壳体50,壳体50包括前表面52,虹膜识别模组40和可见光摄像头24设置在壳体50内并自前表面52露出。
如此,可以利用电子装置100的壳体50保护虹膜识别模组40和可见光摄像头24和便于虹膜识别模组40和可见光摄像头24进行工作。
具体地,将虹膜识别模组40和可见光摄像头24设置在壳体50内,可以利用壳体50防尘防水的作用来保护虹膜识别模组40和可见光摄像头24,从而避免虹膜识别模组40和可见光摄像头24受到外界因素的损坏和影响其进行正常工作。此外,将虹膜识别模组40和可见光摄像头24自前表面52露出可以方便虹膜识别模组40和可见光摄像头24进行工作,避免影响虹膜识别模组40的红外摄像头22和可见光摄像头24采集光线,从而确保虹膜识别模组40和可见光摄像头24能够高效工作。
请参阅图8,在某些实施方式中,红外光源12的照明范围、红外摄像头22的视场和可见光摄像头24的视场至少部分重叠。
如此,红外光源12、红外摄像头22和可见光摄像头24可以协同工作。
具体地,红外光源12和红外摄像头22需要协同合作以实现采集虹膜图像,可以将红外光源12和红外摄像头22设置在电子装置100上的同一侧,并且将红外光源12和红外摄像头22相邻设置,从而使得红外光源12发射的红外光经过物体表面后能被红外摄像头22采集到。此外,红外光源12的照明范围、红外摄像头22的视场和可见光摄像头24的视场至少部分重叠可以方便电子装置100采集虹膜图像,例如,可以利用可见光摄像头24采集人脸图像,从而根据人脸图像的人脸位置信息启动人脸落入对应照明范围的红外光源12和红外摄像头22,从而获得虹膜图像。
请参阅图9,在某些实施方式中,步骤S36包括以下步骤:
S362:判断是否存在人脸落入对应照明范围的红外光源12;
S364:在存在人脸落入对应照明范围的红外光源12时启动人脸落入对应照明范围的红外光源12;和
S366:在不存在人脸落入对应照明范围的红外光源12时发出提醒信息。
请再次参阅图2,在某些实施方式中,处理器30用于:
判断是否存在人脸落入对应照明范围的红外光源12;
在存在人脸落入对应照明范围的红外光源12时启动人脸落入对应照明范围的红外光源12;和
在不存在人脸落入对应照明范围的红外光源12时发出提醒信息。
也即是说,步骤S362、S364和S366可以由处理器30实现。
如此,可以在不存在人脸落入对应照明范围的红外光源12时提示用户。
具体地,在获得人脸图像中的人脸位置信息后,可以先判断是否存在人脸落入对应照明范围的红外光源12,在存在人脸落入对应照明范围的红外光源12时启动人脸落入对应照明范围的红外光源12,从而利用人脸落入对应照明范围的红外光源12为人脸(尤其是人眼)提供红外光,从而方便红外摄像头22采集虹膜图像;在不存在人脸落入对应照明范围的红外光源12时,例如红外光源12都处于电子装置100的上方位置,而人脸位置信息为下方,或者人脸相对于电子装置100的距离太远,可以控制电子装置100发出提醒信息以提示用户此时采集虹膜图像的成功率不高或者无法采集虹膜图像,从而用户可以调整人脸位置以方便电子装置100采集虹膜图像。
请参阅图10,本发明实施方式的电子装置100包括红外光源组件10、摄像头20、一个或多个处理器30、存储器60以及一个或多个程序。其中一个或多个程序被存储在 存储器60中,并且被配置由一个或多个处理器30执行,程序用于执行本发明上述任一实施方式的控制方法的指令。
