具体实施方式
以下结合附图对本发明的实施方式作进一步说明。附图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。
另外，下面结合附图描述的本发明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限制。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅 仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
请参阅图1-3，本发明实施方式的影像传感器10包括像素阵列12和控制电路14。像素阵列12包括光感区122和成像区124。光感区122用于检测光照强度，成像区124用于获取影像。控制电路14用于接收第一指令以控制光感区122检测光照强度，控制电路14用于接收第二指令以控制成像区124获取影像，控制电路14能够同时接收第一指令和第二指令。
本发明实施方式的影像传感器10可应用到本发明实施方式的相机模组100中，相机模组100包括影像传感器10和滤光片20。滤光片20与成像区124对应设置，光线L穿过滤光片20后到达成像区124。
本发明实施方式的相机模组100可应用到本发明实施方式的电子装置1000中，电子装置1000包括相机模组100和处理器200。处理器200与控制电路14连接，处理器200用于生成第一指令和第二指令。在某些实施方式中，电子装置1000还包括显示屏300，显示屏300用于显示视频、图像、文本、图标等数据信息。
上述的影像传感器10、相机模组100和电子装置1000中，控制电路14通过控制一个像素阵列12就可实现检测光照强度和获取影像的功能，避免同时设置一个摄像元件及一个光感元件，减少了元器件的数量，进而可增加用于布置显示屏300的空间的比例，提高电子装置1000的屏占比。
在某些实施方式中，滤光片20可以是RBG滤光片，RGB滤光片可以以拜尔阵列排列，以使得光线L穿过滤光片20后再通过成像区124获取彩色的影像。进一步地，在某些实施方式中，相机模组100还包括可见滤光片30，可见滤光片30与光感区122对应设置，光线L穿过可见滤光片30后到达光感区122，如此，光线L经过可见滤光片30后，光线L中的可见光部分到达光感区122，光感区122可用于检测可见光的光照强度，避免光线L中不可见光，例如红外光、紫外光的干扰。
在某些实施方式中，电子装置1000包括单个相机模组100，单个相机模组100为前置相机模组100a。前置相机模组100a与显示屏300设置在电子装置1000的正面400，前置相机模组100a可用于同时检测正面400的光照强度和获取与正面400相对的影像。
请再结合图3，在某些实施方式中，电子装置1000包括两个相机模组100，两个相机模组100为前置相机模组100a和后置相机模组100b，前置相机模组100a与显示屏300设置在电子装置1000的正面400，后置相机模组100b设置在电子装置1000的背面500，背面500与正面400相背。前置相机模组100a可用于同时检测正面400的光照强度以得到前置光照强度和获取与正面400相对的影像。后置相机模组100b可用于同时检测背面500的 光照强度以得到后置光照强度和获取与背面500相对的影像。
如此，在电子装置1000的使用过程中，处理器200还用于从前置相机模组100a检测得到的前置光照强度，和后置相机模组100b检测得到的后置光照强度中选取较大者作为最终光照强度。以电子装置1000为手机为例，用户在使用中可能存在电子装置1000的正面400与背面500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上等，如果仅仅依据前置相机模组100a检测得到的前置光照强度控制显示屏300的显示亮度，此时显示屏300可能处于不显示或者显示亮度极低的状态，当用户突然重新拿起电子装置1000并使用时，电子装置1000需要重新唤醒显示屏300或者将显示屏300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1000为了控制显示屏300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1000可同时检测后置光照强度，当用户将手机正面朝下放置在桌面上时，显示屏300亮度在一定时间范围内可依据后置光照强度的亮度显示，当用户重新拿起电子装置1000使用时，显示屏300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1000可依据前置光照强度和后置光照强度中的较大的一个来控制显示屏300的显示亮度。例如当用户在室内平躺操作电子装置1000时，背面500可能朝向天花板的光源(如吊灯)等而使得后置光照强度大于前置光照强度，此时电子装置1000可依据后置光照强度来调节显示屏300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。
电子装置1000可以是手机、平板电脑、智能手表等电子装置1000。本发明实施方式以电子装置1000为手机为例进行说明。影像传感器10获取的光照强度可作为调整电子装置1000显示屏300的显示亮度的依据，例如在光照强度较大时增大显示屏300的显示亮度、或者光照强度从较大变化为小于某一阈值时判断用户正在接听电话并关闭显示屏300。影像传感器10获取的影像可在显示屏300中显示，或者存储在电子装置1000的存储介质中以便于读取或转存。
处理器200用于生成第一指令和第二指令，进一步地，处理器200将第一指令和第二指令发送给控制电路14。具体地，处理器200可以单独生成并发送第一指令，或者单独生成或发送第二指令，或者同时生成并发送第一指令和第二指令。第一指令和第二指令可以是处理器200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200接收到用户在手机上触摸或按压指定功能键的操作后生成，第一指令和第二指令也可以是处理器200依据手机的系统时间到达预定的时间点后生成。
控制电路14能够同时接收第一指令和第二指令，也就是说，控制电路14能够同时控 制光感区122检测光照强度和控制成像区124获取影像。当然，控制电路14也能用于单独接收第一指令以控制光感区122检测光照强度，或者单独接收第二指令以控制成像区124获取影像。当控制电路14未接收到第一指令和第二指令时，光感区122和成像区124可均处于不工作的状态。具体地，像素阵列12由多个呈阵列排布的像素组成，位于光感区122内的像素用于检测光照强度，位于成像区124内的像素用于获取图像，每个像素均可依据到达像素的光线的光照强度产生相应的电量。
控制电路14与每个像素电连接，控制电路14依据接收到的第一指令或第二指令获取由对应的像素产生的电量，并进一步通过处理器200分析电量的大小得到到达像素的光线的光照强度，或者进一步通过处理器200综合分析到达多个像素的光线的光照强度以得到影像。
在某些实施方式中，成像区124的面积与像素阵列12的面积的比值大于或等于0.6，和/或光感区122的面积与像素阵列12的面积的比值大于或等于0.1。具体地，成像区124的面积与像素阵列12的面积的比值可以是0.6、0.7、0.77、0.8、0.9等，光感区122的面积与像素阵列12的面积的比值可以是0.1、0.2、0.22、0.4等。如此，保证影像传感器10在具有检测光照强度的功能的基础上，具有较好的成像效果。
请参阅图4和图5，在某些实施方式中，成像区124连续分布且位于像素阵列12的中间位置，光感区122位于成像区124的周缘位置。如此，连续分布的成像区124便于形成连续的、完整的影像。具体地，成像区124的中心可以与像素阵列12的中心重合，成像区124可以是呈中心对称的形状，光感区122可以位于成像区124的一侧或者多侧。
在某些实施方式中，光感区122包括多个子光感区1221，多个子光感区1221的面积相等且间隔设置。
可以理解，光感区122最终检测的光照强度需要综合考虑光感区122内所有像素点检测得到的光照强度，因此，为了得到较为客观的环境光照强度，可以尽可能地将光感区122分散，也就是说，可以将光感区122分散为多个间隔的子光感区1221。
如此，多个子光感区1221间隔设置可扩大光感区122的检测范围同时提高光感区122检测的准确性。在一个实施例中，子光感区1221的数量为四个，每个子光感区1221的面积与像素阵列12的比值可以是0.05，多个子光感区1221可以分别分布在成像区124的上侧、下侧、左侧和右侧。当然，子光感区1221的具体数量和位置不限于上述实施例的讨论。
具体地，请参阅图6，在某些实施方式中，子光感区1221包括左光感区1222和右光感区1223。左光感区1222位于成像区124左侧，右光感区1223位于成像区124右侧，左光感区1222与右光感区1223对称分布，左光感区1222检测得到左光照强度，右光感区1223检测得到右光照强度，光感区122检测得到的光照强度为左光照强度和右光照强度的 均值。
如此，左光感区1222和右光感区1223对最终由光感区122检测到的光照强度的影响基本相同，避免光感区122对成像区124左侧或右侧的光线变化过于敏感而导致整体的检测结果不准确。
在某些实施方式中，子光感区1221包括上光感区1224和下光感区1225。上光感区1224位于成像区124上侧，下光感区1225位于成像区124下侧，上光感区1224与下光感区1225对称分布，上光感区1224检测得到上光照强度，下光感区1225检测得到下光照强度，光感区122检测得到的光照强度为上光照强度和下光照强度的均值。
如此，上光感区1224和下光感区1225对最终由光感区122检测到的光照强度的影响基本相同，避免光感区122对成像区124上侧或下侧的光线变化过于敏感而导致整体的检测结果不准确。
在某些实施方式中，子光感区1221同时包括上述的左光感区1222、右光感区1223、上光感区1224和下光感区1225，左光感区1222与右光感区1223对称分布，上光感区1224与下光感区1225对称，较佳地，左光感区1222、右光感区1223、上光感区1224和下光感区1225呈中心对称分布，左光感区1222检测得到左光照强度，右光感区1223检测得到右光照强度，上光感区1224检测得到上光照强度，下光感区1225检测得到下光照强度，光感区122检测得到的光照强度为左光照强度、右光照强度、上光照强度和下光照强度的均值。
如此，左光感区1222、右光感区1223、上光感区1224和下光感区1225对最终由光感区122检测到的光照强度的影响基本相同，避免光感区122对成像区124左侧、右侧、上侧或下侧的光线变化过于敏感而导致整体的检测结果不准确。
需要说明的是，上述对称分布指的是面积和形状均对称分布且均是关于成像区124对称。
请参阅图7和图8，在某些实施方式中，像素阵列12呈圆形或椭圆形，成像区124呈与像素阵列12内接的矩形，圆形或椭圆形除去内接的矩形之外的区域为光感区122。
如此，成像区124处于像素阵列12的中间位置，易于获取影像，光感区122较分散，在成像区124的左侧与右侧的光感区122对称，光感区122对成像区124的左侧与右侧的光线变化敏感程度相同，同时在成像区124的上侧与下侧的光感区122对称，光感区122对成像区124的上侧与下侧的光线变化敏感程度相同，光感区122的检测结果较准确。
请参阅图9和图10，像素阵列12呈矩形，成像区124呈与矩形内接的圆形或椭圆形，矩形除去内接的圆形或椭圆形之外的区域为光感区122。
如此，成像区124的形状呈圆形或椭圆形，用户可直接通过成像区124获取圆形或椭 圆形的图片而省去后期对照片进行处理的操作，满足用户的个性化需求。同时光感区122较分散，提高光感区122检测得到的光照强度的准确性。
如此，成像区124处于像素阵列12的中间位置，易于获取影像，同时在成像区124的上侧与下侧的光感区122对称，在成像区124的左侧与右侧的光感区122对称。
请参阅图11和图12，在某些实施方式中，成像区124连续分布，光感区122连续分布，成像区124与光感区122由一直线分割。如此，像素阵列12的结构简单，控制电路14接收到第一指令或第二指令后容易定位到对应的成像区124或光感区122的像素。具体地，在一个实施例中，成像区124的面积与像素阵列12的面积的比值为0.8，光感区122的面积与像素阵列12的面积的比值为0.2。成像区124可以呈矩形，以使得成像区124获取呈矩形的影像，光感区122也可以呈矩形，光感区122的长边可以与成像区124的长边相交或者光感区122的长边与成像区124的短边相交。
