具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
全面屏技术越来越多的应用于电子设备上，目前对于搭载有前置摄像头的电子设备，其全面屏的解决方案为：
方案一：在全面屏上设置对应摄像头的透明区域，这种方案造成摄像头对应全面屏上的区域无法进行显示；
方案二：将全面屏做成异型，留出摄像头的对应位置，这种方案美观度差，摄像头周围的屏幕利用率较低，浪费了屏幕的尺寸，没有体现全面屏的高占比率高显示面积的目的。
为了解决上述问题，本申请提出了一种图像处理模块，以实现通过在图像处理模块中设置投影组件和成像组件，实现了采用全面屏方案的电子设备，其图像处理模块对应区域的显示和图像采集功能并存，美观度高，有利于全面屏的发展。
下面参考附图描述本申请实施例的图像处理模块、摄像头和电子设备。
图1为本申请实施例所提供的一种图像处理模块的结构示意图。
如图1所示，该图像处理模块100包括：基板10、投影组件20和成像组件30。
其中，投影组件20和成像组件30均设置于基板10表面。
投影组件20，包括顺序层叠排布的彩膜层201、金属走线层202、发光元件203和驱动元件204，用于投影显示。
具体地，驱动元件204设置于基板10表面，用于驱动发光元件203，金属走线层202设置于驱动元件204表面，与驱动元件204和发光元件203电性连接，发光元件203设置于金属走线层202表面，用于在驱动元件204驱动下发光，彩膜层设置于发光元件203表面，用于滤光。
需要说明的是，驱动元件204可为多个，图中示意性画出了两个，但实际上，不限于两个，可以采用更多或更少驱动元件204，例如驱动元件204可为7个。
成像组件30，包括顺序层叠排布的彩膜层201、金属走线层202和感光元件301，用于采集成像图像。
具体地，感光元件301，设置于基板10表面，用于对彩膜层201滤光得到的光线进行探测，金属走线层202还与感光元件301电性连接。
作为一种可能的实现方式，金属走线层202，包括多条信号线，多条信号线交叉形成的中空区域对应感光元件301所在位置，以使得彩膜层201滤光得到的光线可以通过该中空区 域到达感光元件301。
其中，成像组件30与投影组件20共用金属走线层202和彩膜层201，减小了图像处理模块的体积，同时节约了制造成本。
需要说明的是，图中金属走线层202与感光元件301，驱动元件204以及发光元件203的电性连接仅为示意性连接，本领域技术人员可根据实际需求进行任意方式的排布和电性连接。
本申请实施例的图像处理模块中，投影组件用于投影显示，包括顺序层叠排布的彩膜层、金属走线层、发光元件和驱动元件，成像组件用于采集成像图像，包括顺序层叠排布的彩膜层、金属走线层和感光元件，其中，成像组件与投影组件共用金属走线层和彩膜层，实现了采用全面屏显示方案的电子设备，其图像处理模块对应区域的显示和图像采集功能并存，有利于全面屏的发展。
基于上述实施例，本申请实施例还提出了另一种图像处理模块的结构的可能的实现方式，图2为本申请实施例所提供的另一种图像处理模块的结构示意图，基于上一实施例，如图2所示，发光元件203，还可以包括：金属阳极2031、有机高分子发光层2032和透明阴极2033。
金属阳极2031，设置于金属走线层202表面，用于在发光元件203施加电压时，输出和电子结合的空穴。
有机高分子发光层2032，设置于金属阳极2031表面，用于发光。
透明阴极2033，设置于有机高分子发光层2032表面，用于在发光元件203施加电压时，输出电子。
在一种可能的场景下，图像处理模块100需要进行投影显示时，启动投影组件20进行投影显示，投影组件20可为多个，每一个投影组件20对应一个投影像素点，投影像素点是根据投影显示的图像确定的，为了便于说明，本实施例中以图像处理模块100中包含一个投影组件为例，进行说明，具体地，如图2所示，投影组件20中，在驱动元件204的驱动信号下，给发光元件203施加电压，例如，发光元件203可为有机发光二极管(Organic Light-Emitting Diode，OLED)，电流会从透明阴极2033流向金属阳极2031，并经过有机高分子发光层2032，也就是说，透明阴极2033向有机高分子发光层2032输出电子，金属阳极2031向有机高分子发光层2032输出空穴，而在电子到达有机高分子发光层2032时，会和有机高分子发光层2032的空穴结合，电子和空穴分别带负电和正电，它们相互吸引，激发有机高分子发光层2032中的有机材料发光，从而实现了发光元件203的发光，进而，光经过彩膜层201进行滤光，可产生红、绿、蓝(Red、Green、Blue)三基色，并根据彩膜层201的滤光片颜色的设置，实现不同的滤光需求，从而实现需投影显示的图像的显示。
在另一种可能的场景下，图像处理模块100需要进行采集成像图像时，启动成像组件30进行采集成像图像，成像组件30为多个，每一个成像组件30对应一个成像像素点，成像像素点用于生成成像图像，为了便于说明，本实施例中以图像处理模块100中包含一个成像组件30为例，进行说明，具体地，如图2所示，光线经过彩膜层201进行滤光，感光元件301用于对彩膜层201滤光得到的光线进行探测，使得感光元件301将探测到的光线从光信息转化为数字信号，从而确定该成像组件30对应成像像素点的R、G、B值，即确定了该像素点对应的成像图像，进而根据多个成像组件30对应的多个成像像素点，生成对应的成像图像。
在本实施例的一种可能的实现方式中，多个成像组件30与多个投影组件20，在基板10表面交替排布，这种排布方式可以使得彩膜层201相同颜色采用相同原料进行制造，减少了彩膜层201的制造工序，降低了制造成本。
在本实施例的另一种可能的实现方式中，多个成像组件30与多个投影组件20，在基板10表面分区排布，这种排布方式便于制作工艺简单
本申请实施例的图像处理模块中，投影组件用于投影显示，包括顺序层叠排布的彩膜层、金属走线层、发光元件和驱动元件，成像组件用于采集成像图像，包括顺序层叠排布的彩膜层、金属走线层和感光元件，其中，成像组件与投影组件共用金属走线层和彩膜层，通过在图像处理模块中，设置投影组件进行投影显示，设置成像组件进行图像采集，实现了采用全面屏方案的电子设备，其图像处理模块对应区域的显示和图像采集功能并存，有利于全面屏的发展。
基于上述实施例，本申请实施例还提出了一种摄像头，图3为本申请实施例所提供的摄像头的机构示意图，如图3所示，该摄像头1000包括上述实施例中所述的图像处理模块100和对应成像组件30的透镜组200。
基于上述实施例，本申请实施例还提出了一种电子设备，该电子设备包含移动终端和台式终端等，例如手机、ipad、掌上电脑、台式电脑等等，图4为本申请实施例所提供的一种电子设备的结构示意图。
如图4所示，该电子设备包括：处理单元1010、摄像头1000、以及覆盖摄像头1000的显示屏1020。
显示屏1020，与处理单元1010电性连接，显示屏具有透光区域1021和非透光区域1022，用于在处理单元1010控制下通过非透光区域1022进行显示。其中，透光区域1021的形状可以为矩形，也可以为圆形，也可以为其它形状，本实施例中对此不做限定。另外，透光区域1021的位置本领域技术人员可根据产品的需求灵活设置其在显示屏1020中的位置，本实施例中也不作限定。
摄像头1000，设置于对应透光区域1021下方，包括分别与处理单元1010电性连接的投影组件20和成像组件30，用于在处理单元1010控制下利用投影组件20向显示屏1020投影，以在显示屏1020的透光区域1021进行显示，以及在处理单元1010控制下利用成像组件30透过显示屏1020的透光区域1021采集成像图像。
处理单元1010，用于控制显示屏1020进行显示，以及用于控制摄像头1000在显示状态下投影显示，在成像状态下采集成像图像。
本申请实施例的电子装置中，显示屏与处理单元电性连接，具有透光区域和非透光区域，摄像头设置于对应透光区域下方，包括分别与处理单元电性连接的投影组件和成像组件，用于在处理单元控制下利用投影组件向显示屏投影，以在显示屏的透光区域进行显示，以及在处理单元控制下利用成像组件透过显示屏的透光区域采集成像图像，处理单元，用于控制显示屏进行显示，以及用于控制摄像头在显示状态下投影显示，在成像状态下采集成像图像。通过在摄像头中设置投影组件和成像组件，使得在显示状态下，通过处理单元控制投影组件向显示屏投影，使得显示屏的透光区域也可以对应进行显示，实现了全面屏显示，在成像状态下，通过处理器控制成像组件采集成像图像，实现了图像采集功能，使得电子设备中全面屏显示和图像采集功能可以并存。
基于上述实施例，本申请实施例提供了另一种电子设备的结构的可能的实现方式，图5为本申请实施例提供的另一种电子设备的结构示意图。
如图5所示，处理单元1010，可以包括：图像缓存器1011，处理器1012，与摄像头1000电性连接的第一通信接口1013和与显示屏1020电性连接的第二通信接口1014。
图像缓存器1011，用于对待显示的图像划分为的显示子图像和投影子图像分别进行缓存。
处理器1012，与图像缓存器1011电性连接，用于读取图像缓存器1011得到显示子图像和投影子图像，并向第一通信接口1013发送投影子图像和向第二通信接口1014发送显示子图像。
第一通信接口1013，与处理器1012电性连接，用于将投影子图像发送至摄像头1000。第二通信接口1014，与处理器1012电性连接，用于将显示子图像发送至显示屏1020。作为一种可能的实现方式，第一通信接口1013和第二通信接口1014为同步传输的显示串行接口DSI(Display Serial Interface，DSI)。实现了在显示状态下，通过同步传输的显示串行接口DSI，使得通过第一通信接口1013发送至摄像头1000的投影子图像和通过第二通信接口1014发送至显示屏1020的显示子图像，可以同步发送，从而使得显示屏1020显示的投影子图像和显示子图像同步显示。
作为一种可能的实现方式，图像缓存器1011，可以包括第一缓存区10111和第二缓存区 10112，其中，第一缓存区10111用于存储投影子图像，第二缓存区10112用于存储显示子图像。图6为本申请实施例提供的图像缓存区中数据流向的示意图，如图6所示，通过划分不同的缓存区域，第一缓存区10111中存储了和显示屏1020的非透光区1022对应的图像像素点对应的图像信息，即显示子图像，第二缓存区10112中存储了和显示屏1020的透光区域1021对应的图像像素点对应的图像信息，即投影子图像，从而建立了存储位置和显示屏1020显示区域需要显示的图像的对应关系，以使得当摄像头1000处于显示状态时，处理器1012可以直接从图像缓存器1011的第一缓存区10111中读取投影子图像，通过第一通信接口1013发送给摄像头1000进行投影显示，以及从第二缓存区10112中读取显示子图像，通过第二通信接口1014发送给显示屏1020进行显示，提高了显示屏全屏显示的效率。
对于图像缓存区1011中存储的投影子图像和显示子图像，是根据待显示图像进行子图像划分得到的，而待显示图像进行子图像划分是根据显示屏1020中非透光区域1022的图像像素点对应的图像形状和透光区域1021的图像像素点对应的图像形状进行划分的，作为一种可能的划分方式，图7为本申请实施例提供的子图像划分的示意图之一，如图7所示，显示屏1020中透光区域1021对应的图像像素点对应的图像为正方形，则将待显示图像40根据显示屏1020中透光区域1021和非透光区域1022图像像素点对应的图像形状进行划分，得到图7中右边的投影子图像410和显示子图像420。作为另一种可能的划分方式，图8为本申请实施例提供的子图像划分的示意图之二，如图8所示，显示屏1020中透光区域1021的图像像素点对应的图像为圆形，则将待显示图像40，根据显示屏1020中透光区域1021和非透光区域1022的图像像素点对应的图像形状进行划分，得到图8中右边的投影子图像430和显示子图像440。
需要说明的是，图7和图8中仅示出了根据显示屏1020的透光区域1021和非透光区域1022的图像像素点对应的图像进行显示子图像和投影子图像划分的2种形式，实际应用中，本领域技术人员可根据显示屏1020中透光区域1021和非透光区域1022对应的图像像素点的图像形状，对待显示图像进行划分，划分原理相似，本实施例不一一列举。
本申请实施例的电子设备中，通过在摄像头中设置投影组件和成像组件，使得在显示状态下，通过处理单元控制投影组件向显示屏投影，使得显示屏的透光区域也可以对应进行显示，实现了电子设备的全面屏显示，在成像状态下，通过处理器控制成像组件采集成像图像，实现了图像采集功能，使得电子设备中全面屏显示和图像采集功能可以并存。同时，在显示状态下，通过同步传输的显示串行接口DSI，使得通过第一通信接口发送至摄像头的投影子图像和通过第二通信接口发送至显示屏的显示子图像，可以同步发送，从而使得显示屏在显示状态下显示的投影子图像和显示子图像同步显示。
