背景技术
现有的手机通常均设置有用于自拍的前置摄像头以及用于感测环境光亮度以实现根据环境光亮度调节显示屏亮度的光感器。但目前大多数手机将前置摄像头和光感器分开设置，导致手机中可用于布置显示屏的空间的比例较小，手机屏占比低。
发明内容

具体实施方式
下面详细描述本发明的实施方式，所述实施方式的示例在附图中示出，其中相同或类似的标号自始至终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方式是示例性的，仅用于解释本发明的实施方式，而不能理解为对本发明的实施方式的限制。
请参阅图1，本发明实施方式的影像传感器100包括像素阵列10和控制电路20。像素阵列10包括多个行像素和多个列像素。控制电路20用于控制影像传感器100工作于成像模式或光感模式。
控制电路20还用于：
接收第一指令以控制部分行像素及部分列像素的交叉区域12检测光照强度，以使影像传感器100工作于光感模式；和
接收第二指令以控制像素阵列10获取影像，以使在影像传感器100工作于成像模式。
本发明实施方式的影像传感器100中，由于同一个影像传感器100具有成像模式和光感模式，避免手机等电子装置中同时设置一个摄像元件及一个光感元件，使得手机等电子装置中用于布置显示屏的空间较大，手机屏占比较高。
可以理解，每个行像素和每个列像素均包括多个像素。每个像素均可以获取光照强度信号和影像信号。因此，在影像传感器100工作于成像模式时，像素阵列10可以获取形成在像素阵列10表面上的外界影像。在影像传感器100工作于光感模式时，像素阵列10可以获取照射在像素上的光线的光照强度。
具体地，控制电路20根据第一指令控制交叉区域12进行感光。当前场景的光线到达交叉区域12的每个像素上，交叉区域12中每个像素对应的感光器件会产生电压变化从而获得与每个像素对应的像素值。根据上述的一系列像素值进行计算后得到光照强度。
控制电路20根据第二指令控制像素阵列10获取影像。当前场景的光线到达制像素阵列10每个像素上，制像素阵列10中的每个像素对应的感光器件会产生电压变化从而获得与每个像素对应的像素值。根据上述的一系列像素值进行插值去马赛克等处理后可以获取最终得的影像。
需要说明的是，在影像传感器100工作于成像模式时，可以控制像素阵列10中的全部像素获取影像，当然，也可以控制像素阵列10中部分的像素获取 影像。也即是说，像素阵列10的成像区域可以为像素阵列10的整个区域，也可以为像素阵列10的部分区域。
交叉区域12作为像素阵列10的光感区域，可包括多个像素，形成交叉区域12的每个像素均对应于相应的行像素和相应的列像素。例如，形成交叉区域12的其中一个像素对应于第4行像素和第4列像素。
控制电路20可以控制像素阵列10中的每个像素单独工作，从而控制交叉区域12处于工作状态，而其他区域处于待工作状态。
在一个例子中，其中一个行像素与一个开关连接，其中一个列像素与另一个开关连接，当以上两个开关同时关闭时，则行像素与列像素交叉对应的像素工作。
如图2中的示例，第3行像素与第16列像素交叉对应的像素为P1,第3行像素与第一开关S1连接，第16列像素与第二开关S2连接，当第一开关S1和第二开关S2同时关闭时，则像素P1工作。
当然，在其他实施方式中，还可以通过其他方式控制单个像素工作，例如，每个像素连接单个开关，单个开关闭合时，相应的像素开始工作。
需要指出的是，在影像传感器100工作于成像模式时，交叉区域12也可以获取外界影像。
另外，本实施方式中，像素阵列10呈方形。在其他实施方式中，像素整列可呈多边形或圆形等其他形状，在此不作限定。
在一些实施方式中，交叉区域12位于像素阵列10的中心位置，如图1所示。
如此，光线容易到达位于像素阵列10的中心位置的交叉区域12，使得影像传感器100容易检测光线的强度，影像传感器100检测光线强度的敏感度较佳。
当然，在一些实施方式中，交叉区域12为环形交叉区域12，环形交叉区 域12环绕像素阵列10的中心设置，如图3及图4所示。
具体地，在一些实施方式中，环形交叉区域12呈圆环形，如图3所示。需要说明的是，由于环形交叉区域12包括多个像素，而每个像素可为圆形或多边形等形状，因此，环形交叉区域12的内外边界线可为由多个线段连接而形成，并且大致呈圆形。
在一些实施方式中，环形交叉区域12也可以呈方环形，如图4所示。当然，在其他实施方式中，环形交叉区域12也可以呈除圆环形和方环形外的其他形状，例如呈不规则形状的环形。
较佳地，交叉区域12以像素阵列12的中心呈中心对称设置。如此，像素阵列10的中心周围的区域均能检测光照强度，从而可以提高影像传感器100检测光照强度的灵敏度。
在一些实施方式中，交叉区域12的数量为至少两个，至少两个交叉区域12绕像素阵列10的中心均匀间隔分布。例如，交叉区域12的数量为两个、三个、四个或五个等数量。交叉区域12的具体数量可以根据实际情况具体设定，在此不作限定。另外，每个交叉区域12的形状可为圆形、扇形、多边形等形状，在此不作限定。
在一个例子中，交叉区域12的数量为两个时，两个交叉区域12分别对称地设置于像素阵列10的中心的左右两侧，如图5所示。
具体地，当影像传感器100应用于手机等电子装置300中时，如图10所示，像素阵列10的左右方向对应于电子装置300的横向，也就是说，两个交叉区域12沿电子装置300的横向并列设置，使得电子装置300在横向上倾斜时，交叉区域12均能检测到光照强度，有利于提高影像传感器100检测光照强度的敏感度。
在另一个例子中，交叉区域12的数量为两个时，两个交叉区域12分别对称地设置于像素阵列10的中心的上下两侧，如图6所示。
具体地，当影像传感器100应用于手机等电子装置300中时，像素阵列10的上下方向对应于电子装置300的纵向，也就是说，两个交叉区域12沿电子装置300的纵向并列设置，使得电子装置300在纵向上倾斜时，交叉区域12均能检测到光照强度，有利于提高影像传感器100检测光照强度的敏感度。
在又一个例子中，交叉区域12的数量为四个时，其中两个交叉区域12分别对称地设置于像素阵列10的中心的左右两侧，另外两个交叉区域12分别对称地设置于像素阵列10的中心的上下两侧，如图7所示。
需要指出的是，以上所述的电子装置300的横向例如为图10中所示的左右方向，电子装置300的纵向例如为图10中所示的上下方向。
在再一个例子中，交叉区域12的数量为五个时，交叉区域12绕像素阵列10的中心均匀间隔分布。也就是说，相邻的两个交叉区域12与像素阵列10的中心之间形成的夹角为72°，如图8所示。
在一些实施方式中，在交叉区域12的数量为多个时，全部的交叉区域12的面积均相等。
需要说明的是，在像素阵列12呈规则图形时，像素阵列12的中心为规则图形的几何中心，例如，在像素阵列12呈圆形时，像素阵列12的中心为圆心。又如，在像素阵列12呈方形时，像素阵列12的中心为方形对角线的交叉点。
在像素阵列12呈不规则图形时，像素阵列12的中心为像素阵列12的重心。
在一些实施方式中，交叉区域12的面积A1与像素阵列10的面积A2的比值范围为[0.1，0.4]。,即0.1≤A1/A2≤0.4。例如，A1/A2为0.15、0.2、0.25、0.3、0.35等数值。
A1/A2在以上数值范围时，像素阵列10在保证检测光照强度的同时，可以减少需要工作的像素的数量，以降低影像传感器100的功耗。
请参阅图9，本发明实施方式的相机模组200包括以上任一实施方式的影像传感器100和滤光片210。滤光片210设置于影像传感器100上方。
本发明实施方式的相机模组200中，由于同一个影像传感器100具有成像模式和光感模式，避免手机等电子装置中同时设置一个摄像元件及一个光感元件，使得手机中用于布置显示屏的空间较大，手机屏占比较高。
较佳地，滤光片210为RGB滤光片210，以使影像传感器100获取较佳的图像。RGB滤光片210可以是以拜耳阵列排列，以使光线穿过滤光片210后通过像素阵列10以获取彩色的影像。
当然，在一些实施方式中，滤光片210可以是可见光滤光片210。如此，光线经过可见光滤光片210后，光线中仅可见光部分到达像素阵列10，而其他波段的光线被阻止，交叉区域12可用于检测可见光的光照强度，像素阵列10还可用于获取影像，避免了光线中不可见光的干扰，提升了光感监测的准确性及影响获取的品质。
在一些实施方式中，相机模组200还包括镜头220，镜头220设置于滤光片210的上方。镜头220的光轴222与影像传感器100的中心对齐。
如此，从镜头220穿过的光线较均匀地到达影像传感器100的各个区域，以使影像传感器100的成像效果较佳，并且可以较好地检测光照强度。
具体地，在一些实施方式中，相机模组200还包括电路板230和外壳240。影像传感器100设置于电路板230上，镜头220设置于滤光片210的上方。镜头220设置于外壳240内，并且于外壳240固定连接。
请参阅图10，本发明实施方式的电子装置300包括以上任一实施方式的相机模组200和处理器310，处理器310用于生成第一指令和第二指令。电子装置300例如为手机、平板电脑或智能穿戴设备等具有显示屏的设备。
本发明实施方式的电子装置300中，由于同一个影像传感器100具有成像模式和光感模式，避免手机等电子装置同时设置一个摄像元件及一个光感元件，使得手机中用于布置显示屏的空间较大，手机屏占比较高。
具体地，处理器310将第一指令和第二指令发送给控制电路20。处理器310 可以单独生成并发送第一指令，或者单独生成并发送第二指令。第一指令和第二指令可以是处理器310在接收到输入操作时生成，输入操作可以是用户输入的操作或者是应用环境的输入。
例如，在本发明实施例的手机中，第一指令和第二指令可以是处理器310接收到用户在手机上触摸或按压制定功能键的操作后生成。
又如，第一指令和第二指令也可以是处理器310依据手机的系统时间到达预定的时间点后生成。控制电路20可用于单独接收第一指令以控制交叉区域12检测光照强度，或者单独接收第二指令以控制像素阵列10获取影像。
在一些实施方式中，电子装置300包括单个相机模组200，单个相机模组200为前置相机模组201。如此，单个相机模组200可以获取电子装置300的显示屏320前方的光照强度或物体的影像。
当然，在一些实施方式中，电子装置300包括两个相机模组200，其中一个相机模组200为前置相机模组201，另一个相机模组200为后置相机模组202，如图11所示。
前置相机模组201可以获取电子装置300正面的光照强度或物体的影像，后置相机可以获取电子装置300正面的光照强度或物体的影像。
前置相机模组201中的影像传感器100可以工作于成像模式或光感模式，后置相机模组202中的影像传感器100也可以工作于成像模式或光感模式。也即是说，电子装置300的工作状态包括以下表1中的情况：
表1
Figure PCTCN2018081829-appb-000001
Figure PCTCN2018081829-appb-000002
需要说明的是，影像传感器100的待工作模式指的是，影像传感器100既不处于成像模式，也不处于光感模式，影像传感器100无法检测光照强度及获取影像。
在一个例子中，在处理器310未生成第二指令时，前置相机模组201中的影像传感器100和后置相机模组202中的影像传感器100均工作于光感模式时。电子装置300可以同时获取前置相机模组201周围的光线强度和后置相机模组202周围的光线强度。
以电子装置300为手机为例，用户在使用中可能存在电子装置300的正面与背面的光照强度相差较大的情况。例如，用户可能将手机正面朝下放在桌面登，如果仅仅依据前置相机模组201检测得到的正面光照强度控制显示屏320的显示亮度，此时显示屏320可能处于不显示或显示亮度极低的状态。当用户突然重新拿起电子装置300并使用时，电子装置300需要重新唤醒显示屏320或者将显示屏320的亮度在短时间内调高。当用户频繁拿起和放下时，电子装置300为了控制显示显示屏320的亮度的切换的操作需要耗费的电能较多。
本发明实施方式的电子装置300可同时检测电子装置300的正面和背面光照强度，当用户将手机正面朝下防止在桌面上时，显示屏320的亮度在一定时间范围内可根据背面光照强度的亮度显示，当用户重新拿起电子装置300使用时，显示屏320无需要切换显示亮度，使用方便且节约电能。
在另一个实施例中，电子装置300可根据正面光照强度和背面光照强度中的较大值来控制显示屏320的显示亮度。例如，当用户在室内平躺操作电子装置300时，后置相机模组202可能朝向天花板的光源(如吊灯)等而使得背面光照强度大于正面光照强度。此时电子装置300可根据背面光照强度来调节显 示屏320的显示亮度，更有利于用户看清显示内容，减少用户用眼疲劳。
在另一个例子中，在前置相机模组201中的影像传感器100和后置相机模组202中的影像传感器100中，当其中一个影像传感器100工作于成像模式时，另一个影像传感器100工作于光感模式。
也就是说，当前置相机模组201中的影像传感器100工作于成像模式时，后置相机模组202中的影像传感器100工作于光感模式；或，当前置相机模组201中的影像传感器100工作于光感模式时，后置相机模组202中的影像传感器100工作于成像模式。
如此，处理器310可以根据工作于光感模式的影像传感器100检测到的光照强度控制工作于成像模式的影像传感器100拍摄，以得到品质较佳的图像。例如，当工作于光感模式的影像传感器100检测到的光照强度较弱时，处理器310可以控制工作于成像模式的影像传感器100增大曝光时间已获得亮度较佳的图像。
可以理解，电子装置300还包括电池、供电电路和存储器等元件。电池用于为电子装置300提供电能。供电电路与电池连接，并用于为电子装置300供电。存储器用于存储数据信息，例如程序代码段。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本发明的实施方式的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
