请参阅图1及图2，本申请实施方式的终端100包括显示屏20及成像装置30。显示屏20包括第一显示区21及第二显示区22。成像装置30与第一显示区21对应设置，成像装置30用于接收穿过第一显示区21的光信号以进行成像。
上述终端100中，由于成像装置30与显示屏20的第一显示区21对应设置，成像装置30接收穿过第一显示区21的光信号以进行成像，不需要在显示屏20上开设用于供光信号穿过的通孔，进而提高终端100的屏占比。
具体地，请参阅1及图2，本申请实施方式的终端100包括机壳10、显示屏20、成像装置30及处理器50。终端100的具体形式可以是手机、游戏机、平板电脑、显示器、笔记本电脑、智能手表、头显设备等，本申请以终端100是手机为例进行说明，可以理解，终端100的具体形式并不限于手机，在此不作限制。
机壳10可以是终端100的外壳，例如是手机的中框及后盖。机壳10可以用于安装显示屏20、成像装置30、处理器50等功能器件，功能器件还可以包括主板、电源模块等。终端100还可包括盖板40，盖板40可以由玻璃、蓝宝石、树脂等透明的材料制成，盖板40上可以集成有触控感应层，以感应在盖板40上的触摸操作。盖板40与机壳10可以共同围成收容腔11，显示屏20、成像装置30及处理器50均可以收容在收容腔11内，以使显示屏20、成像装置30及处理器50不易受到水汽及灰尘等的侵蚀。
请继续参阅图1及图2，显示屏20安装在机壳10上，显示屏20可用于发出光信号，光信号穿过盖板40后进入终端100外部，以使显示屏20显示图片、视频、文字等画面。具体地，显示屏20可以安装在机壳10的一个面上，或者同时安装在机壳10的两个面上，例如同时在机壳10的正面及背面上安装显示屏20，或者同时安装在机壳10的两个以上个面上，例如同时在机壳10的正面、背面及侧面上安装显示屏20。在如图1所示的例子中，显示屏20安装在机壳10的正面，显示屏20可以覆盖该正面的面积的90％或以上，例如可以是91％、92％、93％、95％、97％，甚至是100％。显示屏20的整体形状可以是矩形、圆形、椭圆形、跑道形、圆角矩形、三角形等形 状，在此不作限制。
显示屏20包括第一显示区21及第二显示区22。第一显示区21及第二显示区22的显示状态可以被独立控制，例如第一显示区21的熄灭、点亮、显示内容、显示亮度、刷新频率等及第二显示区22的熄灭、点亮、显示内容、显示亮度、刷新频率等均可以被独立控制。其中，熄灭指显示区(第一显示区21或第二显示区22)处于不显示的状态，点亮指显示区(第一显示区21或第二显示区22)处于显示的状态。在一个例子中，第一显示区21与第二显示区22可以共同显示一帧连续的画面，例如第一显示区21与第二显示区22分别显示同一个物体的连续的两部分。在另一个例子中，第一显示区21与第二显示区22可以分别显示不同的画面，例如第二显示区22显示当前画面，第一显示区21显示该当前画面的缩略图，或者第一显示区21可用于显示终端100的电池电量、网络连接状态、系统时间等状态图标。
请参阅图1、图3及图4，第一显示区21可以设置在显示屏20的非角部区域。其中，角部区域指显示屏20的两个边缘相交的部分区域。可以理解，终端100在摔落时，显示屏20的角部区域尤其容易破裂，如果将第一显示区21设置在角部区域，第一显示区21则容易受损，且与第一显示区21对应设置的成像装置30也容易发生移位或者损坏。而将第一显示区21设置在非角部区域可以一定程度上减小第一显示区21及成像装置30损坏的可能性。
具体地，第一显示区21可以设置在显示屏20的至少一个边缘的中间位置，以使用户在使用成像装置30进行自拍时，用户直视显示屏20时也能同时直视成像装置30，自拍的效果较佳。例如在如图1及图3所示的例子中，第一显示区21设置在显示屏20的上边缘的中间位置；在如图4所示的例子中，第一显示区21设置在显示屏20的下边缘的中间位置。当然，在其他例子中，第一显示区21还可以设置在显示屏20的左边缘、右边缘等的中间位置，或者同时设置在两个边缘(例如上边缘及下边缘)的中间位置上，在此不作限制。需要说明的是，本说明书的附图中，第一显示区21与第二显示区22的界线只是为了清楚说明二者之间的界限，并不代表在实际显示中会出现该界线。
第一显示区21及第二显示区22的形状可以依据需求进行设置，例如，第一显示区21可以是矩形、跑道形、水滴形、半圆形、圆形等任意形状，第二显示区22可以与第一显示区21互补形成上述的显示屏20的整体形状，例如，如图1所示，第二显示区22与第一显示区21互补形成圆角矩形的形状显示屏20。第一显示区21的面积可以设置得小于第二显示区22的面积，例如第一显示区21的面积为第二显示区22的面积的十分之一、二十分之一、二十五分之一等比例关系。
显示屏20的具体组成形式可以有不同的选择，在一个例子中，显示屏20为一个独立的屏结构，第一显示区21及第二显示区22能够被独立控制。此时，第一显示区21及第二显示区22为该独立的屏结构的不同的分区，第一显示区21与第二显示区22之间并没有明显的边界。显示屏20可以是OLED显示屏、Micro LED显示屏、或者是由可独立控制的点阵背光源(例如mini led或micro led)作为背光的液晶显示屏。
请参阅图5，在另一个例子中，显示屏20包括能够被独立控制的第一子屏23及第二子屏24，第一显示区21形成在第一子屏23上，第二显示区22形成在第二子屏24上。即，显示屏20由两个独立的子显示装置(第一子屏23及第二子屏24)组成。第一子屏23与第二子屏24在结合成显示屏20时，人眼难以察觉到第一子屏23与第二子屏24之间的交界线。第一子屏23与第二子屏24分别由不同的驱动电路驱动显示。第二子屏24可以形成缺口，缺口例如可以是跑道形、矩形、水滴形等形状，第一子屏23的形状可以与缺口的形状相同，以使第一子屏23与第二子屏24可以结合成较为规则的显示屏20。此时，第一子屏23与第二子屏24可以是同类型的显示装置，例如，第一子屏23与第二子屏24均为OLED显示屏、Micro LED显示屏、或液晶显示屏等任意形式的显示装置中的一种；第一子屏23与第二子屏24也可以是不同类型的显示装置，例如第一子屏23与第二子屏24可以分别是OLED显示屏、Micro LED显示屏、或液晶显示屏等任意形式的显示装置中的不同的两种显示装置，在此不作限制。
请参阅图1及图2，成像装置30安装在的机壳10内。成像装置30与第一显示区21对应设置，成像装置30用于接收穿过第一显示区21的光信号以进行成像。成像装置30与第一显示区21对应设置，可以是成像装置30的入光面朝向第一显示区21，光信号穿过第一显示区21后，可由成像装置30采集并用于成像，或者说，成像装置30设置于显示屏20下，并与第一显示区21对准。
具体地，成像装置30可以是用于依据穿过第一显示区21的可见光信号进行成像的成像装置30，例如成像装置30为彩色相机或黑白相机等；成像装置30还可以是用于依据穿过第一显示区21的不可见光信号进行成像的成像装置30，例如成像装置30为红外相机或紫外相机等；成像装置30还可以是深度相机中的接收装置，例如成像装置30为结构光深度相机中的光接收装置，或者为飞行时间(Time of flight,TOF)深度相机中的光接收装置，在此不作限制。本申请说明书以成像装置30接收可见光信号进行成像为例进行说明。
当显示屏20安装在机壳10的正面时，成像装置30可以是前置成像装置；当显示屏20安装在机壳10的背面时，成像装置30可以是后置成像装置；当然，当显示 屏20同时安装在机壳10的正面及背面时，成像装置30可以包括前置成像装置及后置成像装置。本申请说明书以成像装置30为前置成像装置为例进行示例性说明。
成像装置30可以包括单个摄像头，单个摄像头与第一显示区21对准；成像装置30也可以包括两个摄像头，两个摄像头均与第一显示区21对准；成像装置30也可以包括三个摄像头，三个摄像头均与第一显示区21对准；当然，成像装置30还可以包括更多个摄像头，该更多个摄像头均与第一显示区21对准。
请结合图6，由于成像装置30用于成像的光信号需要穿过第一显示区21，而第一显示区21自身的屏结构可能会对光信号产生影响，例如第一显示区21内的像素25可能会使光信号产生衍射或者削弱光信号的强度等，而导致成像装置30所成的像与实际场景不符。因此，可以考虑通过设计显示屏20及成像装置30的结构来减少这一影响。
具体地，对于显示屏20，可以降低第一显示区21的像素密度以减少对第一显示区21对光信号的作用，如图6所示，可以设置第一显示区21的像素密度小于第二显示区22的像素密度，例如第一显示区21的像素密度为第二显示区22的像素密度的三分之一、二分之一、四分之一等，使得第二显示区22的显示效果较佳，同时成像装置30接收穿过第一显示区21的光信号并用于成像的成像质量较佳。
用于连接第一显示区21的像素25的连接线可以尽可能地转移到第二显示区22内，或者转移到第一显示区21的未与成像面对准的区域内，以减少第一显示区21内的连接线对光信号的影响。同时，第一显示区21的组成部分的选材也可以选择透光率较高的材料，例如选择透明的材料(如ITO)制成像素25的连接线；如果第一显示区21有偏光片，还可选择透明的材料制成偏光片。
对于成像装置30，请结合图7，成像装置30可以选择灵敏度更高的传感器31，在一个例子中，可以增大传感器31的感光单元311的尺寸，例如采用长(L)×宽(h)为1微米×1微米的感光单元311，相较于采用长×宽为0.8微米×0.8微米的感光单元，可以增加每个感光单元311可以接收的光信号的量，得到较佳的成像质量。在一个例子中，在能够满足成像分辨率的情况下，可以将传感器31中的多个感光单元311合并为一个成像单元312使用，该一个成像单元312内的多个感光单元311合计接收的光信号的量用于反映最终成像的单个像素的像素值。一个成像单元312内的感光单元311的数量可以是两个、四个、八个、十六个等任意数量。另外，还可以采用具有更大光圈镜头的成像装置30，以最大限度增加进光量，例如可以采用F2.0、F1.8或更大的光圈。
成像装置30还可与第一显示区21共同配合以减少第一显示区21对光信号的影 响。在一个例子中，在成像装置30进行成像时，第一显示区21处于熄灭状态。第一显示区21处于熄灭状态时，第一显示区21不会主动向外发射光信号，避免第一显示区21发出的光信号直接进入成像装置30而影响成像。具体地，当终端100的处理器50接收到用户的开启成像装置30的指令时，处理器50控制第一显示区21熄灭，同时打开成像装置30，使得成像装置30接收穿过第一显示区21的光信号以进行成像。此时，第二显示区22可以正常显示，例如可以用于显示成像装置30获取的预览画面。当成像装置30使用完毕后，即，成像装置30未进行成像时，第一显示区21与第二显示区22可以均处于点亮状态，具体可以由处理器50控制第一显示区21与第二显示区22共同点亮，以显示较完整的画面，提高用户的使用体验。
在另一个例子中，在成像装置30进行成像时，第一显示区21显示预设画面。具体地，当终端100的处理器50接收到用户的开启成像装置30的指纹时，处理器50控制第一显示区21显示预设画面，同时打开成像装置30，使得成像装置30接收穿过第一显示区21的光信号以进行成像。其中，预设画面可以是固定的画面，以使预设画面对成像的影响较固定，后期容易对所成的像进行校正。预设画面可以是终端100的出厂设置之一，例如预设画面为笑脸、茄子等图案，以辅助用户进行自拍，预设画面还可以是当前的成像参数、或者用于设置成像参数的功能图标等画面。
此时，第二显示区22可以正常显示，例如可以用于显示成像装置30获取的预览画面。当成像装置30使用完毕后，即，成像装置30未进行成像时，第一显示区21与第二显示区22可以均处于点亮状态，具体可以由处理器50控制第一显示区21与第二显示区22共同点亮，以显示较完整的画面，提高用户的使用体验。
请参阅图1及图2，处理器50可以成像装置30及显示屏20均连接。处理器50可用于控制成像装置30及显示屏20的使用状态。另外，处理器50还可用于处理成像装置30所成的像。
如上所述，成像装置30可以用于接收穿过第一显示区21的光信号以进行成像，可以将成像装置30获取的未经处理器50处理的图像称为初始图像。处理器50可以用于处理初始图像以获取最终图像。
由于第一显示区21的屏结构的作用，和/或第一显示区21的显示的预设画面的作用，导致初始图像可能会有亮度偏暗、清晰度较低、图像发雾、光斑(flare)、鬼影(ghost)等缺陷。处理器50再进一步处理初始图像后，可获得质量更高的最终图像。最终图像可以用于最终呈现给用户或进行保存。
一个实施方式中，对于成像装置30获取初始图像时，第一显示区21处于熄灭状态的方式，处理器50可以通过第一算法校正初始图像以获取最终图像，第一算法与 第一显示区21的屏结构相关。由于成像装置30获取初始图像时，第一显示区21处于熄灭状态，故通过与第一显示区21的屏结构相关的第一算法对初始图像进行校正，则可以得到质量较好的最终图像。具体地，第一算法可以包括亮度补偿算法、衍射光斑消除算法、补全算法及去雾算法中的一种或多种，以分别实现对初始图像的亮度补偿、消除初始图像的衍射光斑、补全初始图像中的缺失、去除初始图像中被雾化的部分等功能。
第一算法的数量可以有多个，每个第一算法与一个成像场景对应。处理器50在校正初始图像时，还用于获取与初始图像的成像场景对应的第一算法，及通过对应的第一算法校正初始图像以获取最终图像。不同的成像场景的光信号的强弱、分布情况等性质均不同，因此，针对不同的成像场景，使用对应的第一算法可以对初始图像进行更有针对性的处理。具体地，例如，对于成像场景为暗光场景，对应的第一算法可以更侧重于对初始图像进行亮度补偿；对于成像场景为背光场景，对应的第一算法可以更侧重于对初始图像进行衍射光斑的消除等。
第一算法可以通过标定得到，具体地，请结合图8，如图8a，在第一显示区21处于熄灭状态时，成像装置30接收穿过第一显示区21的光信号以获取测试图像P1，如图8b成像装置30接收未穿过第一显示区21的光信号以获取参考图像P2。处理器50用于依据测试图像P1及参考图像P2获取第一算法。其中，测试图像P1及参考图像P2均是同一个成像装置30对同一个场景进行成像，而由于用于获取测试图像P1的光信号穿过了第一显示区21，用于获取参考图像P2的光信号未穿过第一显示区21，因此，参考图像P2与测试图像P1的细节不同，而参考图像P2更能够体现成像场景的客观情况，例如同一个光源在测试图像P1中为光源200a，在参考图像P2中为光源200b，光源200b的清晰度高于光源200a的清晰度。处理器50将通过人工智能(Artificial Intelligence,AI)深度学习的方式比较测试图像P1及参考图像P2，并得出第一算法。在标定时，成像装置30需要对多个(例如一万个、十万个、百万个等)不同的场景获取测试图像及参考图像，处理器50获取与多个不同的场景一一对应的多个第一算法，以在实际使用中，依据当前的成像场景采用对应的第一算法。
另一个实施方式中，对于成像装置30获取初始图像时，第一显示区21显示预设画面的方式，处理器50可以通过第二算法校正初始图像以获取最终图像，第二算法与第一显示区21的屏结构及预设画面相关。由于成像装置30获取初始图像时，第一显示区21显示预设画面，故通过与第一显示区21的屏结构及预设画面相关的第二算法对初始图像校正，则可以得到质量较好的最终图像。具体地，第二算法可以包括亮度补偿算法、衍射光斑消除算法、补全算法及去雾算法中的一种或多种，以分别实现 对初始图像的亮度补偿、消除初始图像的衍射光斑、补全初始图像中的缺失、去除初始图像中被雾化的部分等功能。
第二算法的数量可以有多个，每个第二算法与一个成像场景对应。处理器50在校正初始图像时，还用于获取与初始图像的成像场景对应的第二算法，及通过对应的第二算法校正初始图像以获取最终图像。不同的成像场景的光信号的强弱、分布情况等性质均不同，因此，针对不同的成像场景，使用对应的第二算法可以对初始图像进行更有针对性的处理。具体地，例如，对于成像场景为暗光场景，对应的第二算法可以更侧重于对初始图像进行亮度补偿；对于成像场景为背光场景，对应的第二算法可以更侧重于对初始图像进行衍射光斑的消除等。
第二算法可以通过标定得到，具体地，请结合图8，如图8a，在第一显示区21处于熄灭状态时，成像装置30接收穿过第一显示区21的光信号以获取测试图像P1，如图8b成像装置30接收未穿过第一显示区21的光信号以获取参考图像P2。处理器50用于依据测试图像P1及参考图像P2获取第二算法。其中，测试图像P1及参考图像P2均是同一个成像装置30对同一个场景进行成像，而由于用于获取测试图像P1的光信号穿过了第一显示区21，用于获取参考图像P2的光信号未穿过第一显示区21，因此，参考图像P2与测试图像P1的细节不同，而参考图像P2更能够体现成像场景的客观情况，例如同一个光源在测试图像P1中为光源200a，在参考图像P2中为光源200b，光源200b的清晰度高于光源200a的清晰度。处理器50将通过人工智能深度学习的方式比较测试图像P1及参考图像P2，并得出第二算法。在标定时，成像装置30需要对多个(例如一万个、十万个、百万个等)不同的场景进行获取测试图像及参考图像，处理器50获取与多个不同的场景一一对应的多个第二算法，以在实际使用中，依据当前的成像场景采用对应的第二算法。
