具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
目前，手机等显示装置上所设置的摄像头模组主要用于拍照，为了防止红外线对呈像产生影响，都设有红外滤光片，这样使得摄像头模组无法捕捉屏幕上方手部的红外信号。因而目前在手机等显示装置上还增设一个额外的红外摄像头模组，才能实现悬浮触控。
针对相关技术中在电子设备上单独设置一个正常拍照摄像头模组和一个额外的红外摄像头模组才能实现拍照及悬浮触控功能，存在占用空间大、结构不紧凑、不利于整机空间布局的技术问题，本公开实施例中提供一种悬浮触控摄像头模组、显示装置及触控方法，通过同一摄像头模组既能实现拍照功能，又能实现悬浮触控功能，结构紧凑，可减少占用空间，提高整机设计空间面积利用率。
如图1至图4所示，本公开实施例中所提供的悬浮触控摄像头模组，包括：
用于采集光线的镜头100，所述镜头100包括采光面和出光面；
能够接收来自所述镜头100的光线，并形成感应信息的影像传感器200，设置于所述镜头100的出光面一侧；
及，用于过滤掉红外光线的红外截止滤光膜300，设置于所述镜头100的所述采光面一侧、和/或设置于所述镜头100与所述影像传感器200之间；
其中，所述红外截止滤光膜300与所述镜头100之间可相对移动，以使所述悬浮触控摄像头模组能够在拍照模式和触控模式之间切换；
在所述拍照模式，所述红外截止滤光膜300位于与所述镜头100正对的第一位置，以使所述镜头100中所采集的光线被过滤掉红外线后，进入所述 影像传感器200；
在所述触控模式，所述红外截止滤光膜300位于与所述镜头100错开的第二位置，以使所述镜头100中所采集的光线中包括红外线，进入所述影像传感器200。
在一些实施例中，影像传感器200上与所述镜头100的出光面相邻的一面为入光面。
上述方案，通过将红外截止滤光膜300设计为可相对于镜头100移动，当需要进行拍照时，将所述红外截止滤光膜300与所述镜头100正对，这样，自然光线中的红外线会被过滤掉之后进入影像传感器200，以防止红外线对正常呈像的影响，通过该悬浮触控摄像头模组可还原出真实的色彩，而不会干扰色彩还原，从而实现该悬浮触控摄像头模组的拍照功能；而当需要进行悬浮触控时，则可将所述红外截止滤光膜300与镜头100错开，这样，所述红外截止滤光膜300停止工作，则该悬浮触控摄像头模组中进入影像传感器200的光线为包括红外光线的全光谱光，捕捉手部动作，则可实现悬浮触控的功能。
由此可见，本公开实施例所提供悬浮触控摄像头模组，通过这一个摄像头模组，既能实现拍照功能，拍出正常照片，又能在需要悬浮触控时，对包括红外光线在内的全光谱光线进行收集，实现悬浮触控功能，与相关技术中在电子设备上单独设置一个普通拍照摄像头模组和一个额外的红外摄像头模组的方式相比，结构紧凑，可减少摄像头占用空间，有利于电子设备整机结构布局。
需要说明的是，在所述悬浮触控摄像头模组中，所述红外截止滤光膜300是设置在所述镜头100的采光面、或者所述镜头100的出光面均可，只要能够使从所述镜头100采集的自然光线中的红外线被所述红外截止滤光膜300过滤掉之后，进入影像传感器200即可。示例性的，如图1至图2所示，所述红外截止滤光膜300设置在所述镜头100的采光面一侧；如图8中虚线所示的红外截止滤光膜300’设置在所述镜头100和影像传感器200之间。
还需要说明的是，在上述方案中，所述红外截止滤光膜300与所述镜头100之间可相对移动，可以是，在将该悬浮触控摄像头模组安装于电子设备 上之后，通过移动所述红外截止滤光膜300实现，也可以是，通过移动所述镜头100来实现。
此外，在本公开实施例所提供的悬浮触控摄像头模组中，示例性的，如图1至图4所示，所述悬浮触控摄像头模组还包括增透膜400，所述增透膜400设置于所述镜头100的所述采光面一侧、和/或设置于所述镜头100与所述影像传感器200之间；其中，所述增透膜400与所述镜头100之间可相对移动，在所述拍照模式，所述增透膜400位于与所述镜头100错开的第三位置；在所述触控模式，所述增透膜400位于与所述镜头100正对的第四位置。
采用上述方案，在所述悬浮触控摄像头模组中，还设置有一增透膜400，且该增透膜400也可以相对于所述镜头100移动，这样，在拍照模式下，该增透膜400可移动至与所述镜头100错开的位置，而此时，所述红外截止滤光膜300移动至与所述镜头100正对的位置，所述红外截止滤光膜300工作，将所述镜头100采集的自然光线中的红外光线过滤掉，以防止红外线对正常呈像的影响，通过该悬浮触控摄像头模组可还原出真实的色彩，而不会干扰色彩还原；在触控模式下，该增透膜400可移动至与所述镜头100正对的位置，而此时，所述红外截止滤光膜300移动至与所述镜头100错开的位置，这样，该增透膜400可增强进入所述影像传感器200的光线的透射强度，从而可使得该悬浮触控摄像头模组充分接收包括红外光线的自然光，而对手部动作进行捕捉，实现悬浮触控。
需要说明的是，在上述方案中，所述增透膜400可以为全光谱增透膜，这样，可以使得在所述触控模式下，进入所述影像传感器200的光线为包括红外光线的全光谱光线。当然可以理解的是，在实际应用中，根据实际需要，所述增透膜400也可以是其他类型的增透膜400，对此不进行限定。
此外，所述增透膜400可设置在所述镜头100的采光面一侧，也可以设置在所述镜头100的出光面一侧，对此不进行限定。
此外，还需要说明的是，在上述示例性的实施例中，所述增透膜400在所述拍照模式下会移动至与所述镜头100错开的位置；在其他实施例中，由于所述增透膜400可以起到增加光线的透射强度的作用，如图3和图4所示，所述增透膜400还可以是始终固定设置于与所述镜头100正对的位置，这样， 在所述拍照模式和所述触控模式这两种模式下，所述增透膜400均与所述镜头100正对，可增加进入该悬浮触控摄像头模组内的光线透射强度。
此外，所述悬浮触控摄像头模组还包括移动结构，所述增透膜400与所述红外截止滤光膜300均通过所述移动结构的驱动进行移动，且所述红外截止滤光膜在所述移动结构的驱动下，从所述第一位置移动至所述第二位置时，所述增透膜400正好从所述第三位置移动至所述第四位置。在一些实施例中，所述第一位置和所述第四位置均为与所述镜头100正对的位置。
采用上述方案，所述红外截止滤光膜300和所述增透膜400可以通过同一移动结构进行移动，可以同步来移动所述红外截止滤光，且该移动结构能够在需要进行拍照模式和触控模式切换时，同步完成所述红外截止滤光膜300和所述增透膜400的位置改变，例如：
所述移动结构可包括滑轨及可在滑轨上移动的支架，如图1和图2所示，所述红外截止滤光膜300和所述增透膜400可设在所述镜头100一侧，并在所述支架带动下平行滑动，所述红外截止滤光膜300与所述增透膜400通过该支架连接，且所述红外截止滤光膜300位于所述增透膜400的一侧，当所述移动结构将所述支架沿图1中F方向滑动时，所述红外截止滤光膜300从所述镜头100正对的第一位置沿图1所示F方向移动至与所述镜头100错开的第二位置，此时，所述增透膜400也正好在所述支架带动下沿图1所示F方向，从与所述镜头100错开的第三位置移动至与所述镜头100正对的第四位置。
需要说明的是，对于所述移动结构的具体结构并不限定于此，其可实现方式可以有多种，比如，如图7所示，所述移动结构还可以包括旋转轴510及连接在所述旋转轴上的旋转盘530，其中所述红外截止过滤膜和所述增透膜400可设置在该旋转盘上，当旋转所述旋转盘时，则所述红外截止过滤膜和所述增透膜400均可随所述旋转盘进行移动，实现位置变化，而实现所述红外截止过滤膜与所述镜头100正对或与所述镜头100错开、以及所述增透膜400与所述镜头100正对或与所述镜头100错开。在一实施例中，所述旋转盘530是透明的。
此外，在本公开实施例所提供的悬浮触控摄像头模组中，示例性的，所 述悬浮触控摄像头模组还可以包括：
用于检测外界环境光线强度的光线强度检测单元；
及，用于在外界环境光线强度小于或等于预设值时，以预定频率闪烁，以向外界环境照射红外光线的红外补光灯，与所述光线强度检测单元连接。
采用上述方案，通过设置所述光线强度检测单元，可对外界环境光线强度进行检测，所述红外补光灯可向外界环境照射红外光线进行补光，这样，该悬浮触控摄像头模组在触控模式下，当外界环境光充足时(如：白天)，所述影像传感器200充分接收包括红外光线的自然光，形成感应信息，而捕捉手部动作，得到手势动作信息，实现悬浮触控；而当外界环境光不足时(如：夜晚)，可通过所述红外补光灯闪烁，来向外界环境照射红外光线进行补光，此时，所述影像传感器200会接收来自所述镜头100的两种光线，一种是正常外界环境光线，另一种是红外补光灯亮起时的外界环境光线。所述影像传感器200在接收正常环境光线时，形成第一感应信息；所述影像传感器200在接收红外补光灯亮起时的外界环境光线时，形成第二感应信息。这样，可形成两个不同的手势轮廓图像，电子设备可通过图像识别与图像融合校正来精准捕捉动作命令，实现悬浮触控。
此外，如图5所示，在本公开实施例中还提供了一种电子设备，包括：
本公开实施例中所提供的悬浮触控摄像头模组10；
及，与所述影像传感器200电连接的图像处理单元500，用于在所述悬浮触控摄像头模组10处于所述拍照模式时，对所述影像传感器200的感应信息进行处理，得到图像信息；以及，在所述悬浮触控摄像头模组10处于所述触控模式时，对所述影像传感器200的感应信息进行识别，得到手势动作信息。
上述方案，通过将红外截止滤光膜300设计为可相对于所述镜头100移动，当所述悬浮触控摄像头模组10为拍照模式时，将所述红外截止滤光膜300与所述镜头100正对，这样，自然光线中的红外线会被过滤掉之后进入影像传感器200，以防止红外线对正常呈像的影响，所述图像处理单元500则可对所述影像传感器200的感应信息进行处理，而得到图像信息，实现拍照功能，由于红外线被过滤掉，可还原出真实的色彩，而不会干扰色彩还原； 而当所述悬浮触控摄像头模组10为触控模式时，则所述红外截止滤光膜300与所述镜头100错开，这样，所述红外截止滤光膜300停止工作，则该悬浮触控摄像头模组10中进入影像传感器200的光线为包括红外光线的全光谱光，对手部动作进行捕捉，所述图像处理单元500即对所述影像传感器200的感应信息进行识别，得到手势动作信息，实现悬浮触控功能。
由此可见，本公开实施例所提供的电子设备，通过设置一个悬浮触控摄像头模组10，既能实现拍照功能，拍出正常照片，又能在需要悬浮触控时，对包括红外光线在内的全光谱光线进行收集，实现悬浮触控功能，与相关技术中在电子设备上单独设置一个普通拍照摄像头模组和一个额外的红外摄像头模组的方式相比，结构紧凑，可减少摄像头所占用空间，有利于电子设备整机结构布局。

其中，所述图像处理单元500还与所述识别单元701连接，用于根据所述识别单元701所识别的用户操作指令，对所述影像传感器200的感应信息进行相应识别和处理。
采用上述方案，可通过设置所述识别单元701，判断当前用户操作指令， 即，判断用户当前操作是拍照操作还是触控操作，并将判断结果发送至所述控制单元800及所述图像处理单元500。所述控制单元800在用户当前操作为拍照操作时，切换至所述拍照模式，在用户当前操作为触控操作时，切换至所述触控模式。所述图像处理单元500在用户当前操作为拍照操作时，对所述影像传感器200的感应信息进行识别和处理，并形成图像信息，以实现拍照功能；在用户当前操作为触控模式时，对所述影像传感器200的感应进行信息识别和处理，并形成手势动作信息，以实现触控功能。
需要说明的是，在上述方案，所述识别单元701可以是采用人脸识别模块或者微距判断模块来对用户当前操作进行识别，以此来实现当用户打开摄像头时，自动根据用户当前操作来实现拍照或触控功能的目的。当然可以理解的是，在实际应用中，也可以是通过手动开启方式，来开启所述悬浮触控摄像头模组10的拍照模式或者触控模式。
图6所示为本公开上述可选实施例中所提供的电子设备的工作流程图。
如图6所示，该电子设备的工作流程为：
S1、打开该电子设备的悬浮触控摄像头模组；
S2、判断当前用户操作指令，所述用户操作指令包括用户当前操作为拍照操作或用户当前操作为触控操作；
S3、当用户当前操作为拍照操作时，切换所述悬浮触控摄像头模组为拍照模式，所述图像处理单元500对所述影像传感器200的感应信息进行识别和处理，形成图像信息，以进行正常拍照；
S4、当用户当前操作为触控操作时，切换所述悬浮触控摄像头模组为触控模式；
S5、检测外界环境光强度，判断外界环境光是否充足；
S6、当外界环境光强度大于预设值时，所述红外补光灯700关闭，所述图像处理单元500对所述影像传感器200的感应信息进行识别和处理，形成手势动作信息，以实现触控；
S7、当外界环境光强度小于或等于预设值时，所述红外补光灯700开启，所述图像处理单元500对所述影像传感器200的第一感应信息和第二感应信息进行识别和处理，形成手势动作信息，以实现触控，其中所述第一感应信 息为所述影像传感器200在所述红外补光灯700亮起时的感应信息，所述第二感应信息为所述影像传感器200在所述红外补光灯700暗下时的感应信息。
此外，本公开实施例中还提供了一种触控方法，应用于本公开实施例中的电子设备中，所述方法包括：
步骤S01、在悬浮触控摄像头模组为拍照模式时，控制红外截止滤光膜300位于与镜头100正对的第一位置，对影像传感器200的感应信息进行处理，并得到图像信息；
步骤S02、在悬浮触控摄像头模组为触控模式时，控制红外截止滤光膜300位于与镜头100错开的第二位置，对影像传感器200的感应信息进行识别，并得到手势动作信息。
上述方案，当需要进行拍照时，将所述红外截止滤光膜300与所述镜头100正对，这样，自然光线中的红外线会被过滤掉之后进入影像传感器200，以防止红外线对正常呈像的影响，通过该悬浮触控摄像头模组可还原出真实的色彩，而不会干扰色彩还原，从而实现该悬浮触控摄像头模组的拍照功能；而当需要进行悬浮触控时，则可将所述红外截止滤光膜300与镜头100错开，这样，所述红外截止滤光膜300停止工作，则该悬浮触控摄像头模组中进入影像传感器200的光线为包括红外光线的全光谱光，捕捉手部动作，则可实现悬浮触控的功能。
由此可见，本公开实施例所提供的触控方法，通过同一个摄像头模组中的红外截止滤光膜300与镜头100之间相对位置改变，既能实现拍照功能，拍出正常照片，又能在需要悬浮触控时，对包括红外光线在内的全光谱光线进行收集，实现悬浮触控功能，与相关技术中在电子设备上单独设置一个普通拍照摄像头模组和一个额外的红外摄像头模组的方式相比，结构紧凑，可减少摄像头占用空间，有利于电子设备整机结构布局。
此外，在本公开所提供的可选实施例中，所述悬浮触控摄像头模组还包括增透膜400，所述方法还包括：
在所述悬浮触控摄像头模组为拍照模式时，控制所述增透膜400位于与所述镜头100错开的第三位置；
在所述悬浮触控摄像头模组为触控模式时，控制所述增透膜400位于与 所述镜头100正对的第四位置。
采用上述方案，在所述悬浮触控摄像头模组中，还设置有一增透膜400，且该增透膜400也可以相对于所述镜头100移动，这样，在正常拍照模式下，该增透膜400可移动至与所述镜头100错开的位置，而此时，所述红外截止滤光膜300移动至与所述镜头100正对的位置，所述红外截止滤光膜300工作，将所述镜头100采集的自然光线中的红外光线过滤掉，以防止红外线对正常呈像的影响，通过该悬浮触控摄像头模组可还原出真实的色彩，而不会干扰色彩还原；在悬浮触控模式下，该增透膜400可移动至与所述镜头100正对的位置，而此时，所述红外截止滤光膜300移动至与所述镜头100错开的位置，这样，该增透膜400可增强进入所述影像传感器200的光线的透射强度，从而可使得该悬浮触控摄像头模组充分接收包括红外光线的自然光，而对手部动作进行捕捉，实现悬浮触控。
需要说明的是，在上述方案中，所述增透膜400可以为全光谱增透膜，这样，可以使得在所述触控模式下，进入所述影像传感器200的光线为包括红外光线的全光谱光线。当然可以理解的是，在实际应用中，根据实际需要，所述增透膜400也可以是其他类型的增透膜400，对此不进行限定。此外，所述增透膜400可设置在所述镜头100的采光面一侧，也可以设置在所述镜头100的出光面一侧，对此不进行限定。
此外，还需要说明的是，在上述示例性的实施例中，所述增透膜400在所述拍照模式下会移动至与所述镜头100错开的位置；在其他实施例中，由于所述增透膜400可以起到增加光线的透射强度的作用，所述方法中，在所述悬浮触控摄像头模组为拍照模式和触控模式时，还可以控制增透膜400均与镜头100正对设置。
采用上述方案，所述增透膜400还可以是固定设置于与所述镜头100正对的位置，这样，在所述拍照模式和所述触控模式这两种模式下，所述增透膜400始终与所述镜头100正对，增加进入该悬浮触控摄像头模组内的光线透射强度。
此外，在本公开所提供的可选实施例中，上述步骤S02具体包括：
步骤S021、在外界环境光线强度小于或等于预设值时，控制红外补光灯 700开启，对影像传感器200的第一感应信息和第二感应信息进行识别和处理，得到手势动作信息；其中所述第一感应信息为所述影像传感器200在所述红外补光灯700亮起时的感应信息，所述第二感应信息为所述影像传感器200在所述红外补光灯700暗下时的感应信息。
此外，上述所述步骤S02具体还包括：
步骤S022、在外界环境光线强度大于所述预设值时，控制红外补光灯700关闭，对影像传感器200的感应信息进行识别和处理，得到手势动作信息。
采用上述方案，该悬浮触控摄像头模组在所述触控模式下，且外界环境光充足时，所述影像传感器200充分接收包括红外光线的自然光，形成感应信息，而捕捉手部动作，所述图像处理单元500对该感应信息进行识别和处理，得到手势动作信息，实现悬浮触控。该悬浮触控摄像头模组在所述触控模式下，且当外界环境光不足时，可通过所述红外补光灯700闪烁，来向外界环境照射红外光线进行补光。此时，所述影像传感器200将接收来自所述镜头100的两种光线，一种是正常环境光线，另一种是红外补光灯700亮起时的光线。所述影像传感器200接收正常环境光线形成第一感应信息，接收红外补光灯700亮起时的光线形成第二感应信息。这样，可形成两个不同的手势轮廓图像，图像处理单元500可通过图像识别与图像融合校正来精准捕捉动作命令，实现悬浮触控。
此外，在本公开所提供的可选实施例中，在上述步骤S01之前，所述方法还包括：
步骤S11、判断所述悬浮触控摄像头模组打开时的用户操作指令，所述用户操作指令包括用户当前操作为拍照操作或用户当前操作为触控操作；
步骤S12、根据判断结果，控制所述悬浮触控摄像头模组在所述拍照模式和所述触控模式之间切换。
采用上述方案，在摄像头打开时，首先判断当前用户操作指令，即，识别用户当前操作是拍照操作还是触控操作，并将判断结果发送至所述控制单元800及所述图像处理单元500；所述控制单元800在用户当前操作为拍照操作时，切换至所述拍照模式，在用户当前操作为触控操作时，切换至所述触控模式。所述图像处理单元500在用户当前操作为拍照操作时，对所述影 像传感器200的感应信息进行识别和处理，并形成图像信息，以实现拍照功能，在用户当前操作为触控模式时，对所述影像传感器200的感应进行信息识别和处理，并形成手势动作信息，以实现触控功能。
以上所述的是本公开的可选实施方式，应当指出对于本技术领域的普通人员来说，在不脱离本公开所述原理前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
