图1为一个实施例中屏幕漏光量确定方法的应用环境示意图。如图1所示，该应用环境包括具有屏幕的电子设备102和服务器104。电子设备102的屏幕用于显示画面，显示的画面可以为电子设备102本地存储的内容或由服务器104下发的内容，电子设备102确定屏幕的目标显示内容，并从预设的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
其中，电子设备102可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑、智能手表、智能手环和其他便携式可穿戴设备，服务器104可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
图1也可以作为一个实施例中屏幕亮度调节方法的应用环境示意图。如图1所示，电子设备102的屏幕用于显示画面，显示的画面可以为电子设备102本地存储的内容或由服务器104下发的内容，电子设备102获取环境光感量，并确定屏幕在显示目标显示内容情况下所对应的屏幕漏光量，屏幕漏光量通过从预设的漏光映射关系中查询得到。电子设备102根据环境光感量和屏幕漏光量得到实际光感量，如可以从环境光感量中去除屏幕漏光量的影响，获得能够准确反映环境光照强度的实际光感量，并基于实际光感量对屏幕进行亮度调节，有效降低了屏幕亮度调节的成本，提高了屏幕亮度调节的处理效率。
图2为一个实施例中屏幕漏光量确定方法的流程图。本实施例中的屏幕漏光量确定方法，以运行于图1中的电子设备上为例进行描述。如图2所示，屏幕漏光量确定方法包括操作202至操作204。
操作202，确定屏幕的目标显示内容。
具体地，屏幕为电子设备的显示屏幕，用于显示电子设备上的画面。目标显示内容指需要在电子设备的屏幕上显示的画面或已经在电子设备的屏幕上显示的画面。即屏幕漏光量确定方法，可以在屏幕需要显示目标显示内容之前实现，也可以在电子设备的屏幕已经显示对应目标显示内容之后实现。
例如，电子设备为手环时，目标显示内容可以为手环预先配置的各种画面，如表盘、设置界面、睡眠监控界面、运动界面等。对于不同的电子设备，具有不同的目标显示内容，可以显示的目标显示内容的数量也不相同。
操作204，从预设的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量；其中，漏光映射关系包括屏幕在显示各种显示内容的情况下，分别对应的屏幕漏光量。
其中，漏光映射关系包括屏幕在显示各种显示内容的情况下，分别对应的屏幕漏光量。电子设备在显示不同显示内容时，因屏幕自身发光不同，导致屏幕的漏光量也不同。例如，如图3所示，在电子设备的屏幕的显示内容为色彩丰富、明亮的白天的画面时，屏幕显示时自身的发光较强，屏幕漏光量较大。而如图4所示，在电子设备的屏幕的显示内容为暗淡的 深夜的画面时，屏幕显示时自身的发光较弱，屏幕漏光量较小。具体地，可以预先确定电子设备需要显示的各种显示内容，并确定各种显示内容对应的屏幕漏光量，如可以通过控制电子设备的屏幕在显示各种显示内容时，测量得到电子设备的屏幕在显示各种显示内容时分别对应的屏幕漏光量。根据电子设备需要显示的各种显示内容及对应的屏幕漏光量，构建得到漏光映射关系。
在具体实现时，考虑到各种电子设备的屏幕显示画面的多样性，可以对屏幕的目标显示内容进行归纳。例如，在电子设备屏幕的目标显示内容的数量有限，如为确定的100个显示内容时，可以构建100个显示内容与对应屏幕漏光量之间的映射关系，得到漏光映射关系。而在电子设备屏幕的目标显示内容的数量较大，如智能手机可以通过应用程序连接互联网获取互联网中各种信息进行展示时，屏幕的显示内容数量难以穷举，则可以对显示内容进行分类归纳。如可以按照应用程序类别进行分类归纳，确定各种应用程序对应显示内容的屏幕漏光量，例如，可以按照对应用程序中支持的显示内容进行显示试验，获得根据各次试验结果得到应用程序对应的屏幕漏光量。也可以按照屏幕的界面进行分类归纳，如屏幕显示的界面为音乐播放界面、视频播放界面、网页等，确定为不同的显示内容，并测量相应的屏幕漏光量后建立漏光映射关系。此外，还可以设置通用显示内容和通用屏幕漏光量之间的映射关系，通用屏幕漏光量可以根据实际应用场景进行设置。在无法明确屏幕目标显示内容时，如目标显示内容不属于漏光映射关系中的显示内容时，可以确定屏幕显示的为通用显示内容，并根据通用显示内容对应的通用屏幕漏光量确定为屏幕在显示目标显示内容情况下的屏幕漏光量。
在具体应用时，电子设备可以查询预设的漏光映射关系，漏光映射关系包括电子设备的屏幕在显示各种显示内容的情况下，分别对应的屏幕漏光量。电子设备根据从漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。如可以将目标显示内容的目标内容标识与漏光映射关系中各种显示内容的内容标识进行匹配，将与目标内容标识匹配一致的内容标识对应的屏幕漏光量，确定为屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
在具体实现中，在智能手表或手环等电子设备上都会设有ALS(Ambient Light Sensor)环境光传感器，主要用于在不同的环境光亮度下，自动调节屏幕亮度。为了使智能手表或手环等电子设备的外观更具有吸引力，一般ALS不会单独设计开孔，而是直接将传感器设置在AMOLED(Active-matrix organic light-emitting diode，有机发光显示屏)屏幕底下，利用屏幕微弱的透光性能(约2％～3％透过率)来完成环境光检测。如图5所示，屏下的ALS会同时接收到环境光以及AMOLED屏自身发光产生的漏光。实现屏幕亮度调节需要检测的是外界环境光，而屏幕自发光会影响ALS的感应值从而形成干扰，要准确获取外界环境光强度，需要通过算法将屏幕自身发光的部分影响去除。
假设ALS获取的光感量原始值为Raw_data,其中环境光产生的光感量为A_data,A_data为环境光透过屏幕后由ALS感知得到，A_data反映了屏幕上方环境的实际光照强度，屏幕产生的漏光量为L_data，那么有Raw_data＝A_data+L_data，从而得到环境光生产的感应值A_data＝Raw_data–L_data。其中，Raw_data是ALS传感器实时输出的值，可以直接读取，那么如何准确的计算屏幕自身的漏光量L_data成为屏幕亮度自动调节的关键技术点。
传统的处理方案中，可以通过截屏算法，抓取光感区域的屏幕显示内容计算当前屏蔽的漏光量。这种方法需要实时地截取当前屏幕显示内容并计算当前屏幕的漏光量，每次截屏和计算需要大量的数据处理，占用较多的CPU资源和功耗，给续航带来很大的负担，尤其是像手表、手环等电池容量有限，续航要求又高的电子设备。此外，传统的处理方案中，由于截屏计算需要提前拟合屏幕漏光趋势公式，该公式只能通过拟合得到，再反过来通过公式来计算屏幕漏光量，会存在一定的误差，导致屏幕漏光量确定的准确性有限。如图6所示，在一个具体实施例的截屏算法的公式拟合处理中，各曲线的横纵坐标单位均为像素；红色拟合曲线为曲线1，其曲线公式为R_Comp＝R_Cal*[0.00002*R 3+0.001*R 2+0.4942*R]，拟合的可决系 数R R 2＝0.9999，曲线1对应纵坐标为R_Comp，指红色拟合结果，横坐标R为红色像素值，R_Cal为红色校准系数；绿色拟合曲线为曲线2，其曲线公式为G_Comp＝G_Cal*[0.00002*G 3+0.0009*G 2+0.34565*G]，曲线2对应纵坐标为G_Comp，指绿色拟合结果，横坐标R为绿色像素值，G_Cal为绿色校准系数，拟合的可决系数R G 2＝0.9998；蓝色拟合曲线为曲线3，其曲线公式为B_Comp＝B_Cal*[0.000008*B 3+0.001*B 2+0.1564*B]，拟合的可决系数R B 2＝0.9995，曲线3对应纵坐标为B_Comp，指蓝色拟合结果，横坐标R为蓝色像素值，B_Cal为蓝色校准系数。拟合的可决系数反映了拟合优度，可决系数越接近1，拟合程度越高。拟合存在一定误差，一般不能得到完全拟合，即可决系数为1的拟合曲线。
而本实施例中，对于智能手表或手环等电子设备，其显示内容的画面数量有限，可以通过穷举出电子设备屏幕的各种显示内容，并确定屏幕在显示各种显示内容时分别对应的屏幕漏光量，从而构建电子设备的漏光映射关系。在确定电子设备屏幕的目标显示内容时，直接从漏光映射关系中可以查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，从而避免了对屏幕显示内容的截屏和漏光量计算处理，减少了计算资源的消耗，降低了确定屏幕漏光量的成本，提高了屏幕漏光量的确定效率。同时，漏光映射关系预先建立，通过查询直接确定，不需要进行公式拟合，降低了确定屏幕漏光量的误差，提高了确定屏幕漏光量的准确率，从而确保了屏幕亮度调节的效果。
本实施例中的屏幕漏光量确定方法，通过从预设的包括屏幕在显示各种显示内容的情况下，分别对应的屏幕漏光量的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，可以在确定屏幕的目标显示内容后，从预设的漏光映射关系中直接查询得到对应的屏幕漏光量，不需要耗费大量资源进行屏幕漏光计算，有效降低了确定屏幕漏光量的成本，提高了确定屏幕漏光量的处理效率。
在一个实施例中，在从预设的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量之前，还包括：确定屏幕的目标亮度级别。
其中，目标亮度级别表征电子设备的屏幕在进行显示时的亮度大小，目标亮度级别可以由用户设定，如用户在电子设备的显示亮度界面，通过亮度调节控件设置屏幕的目标亮度级别。屏幕的目标亮度级别也可以由电子设备根据预设的亮度设置条件进行灵活设定，如可以根据电子设备屏幕的显示内容类别设置对应的亮度级别，例如，在电子设备显示二维码进行支付时，为确保二维码能够成功被扫描，可以将屏幕的目标亮度级别设置较高。又如，可以根据电子设备环境光强度设置对应的亮度级别，例如，电子设备在获得ALS传感器感知的环境光强度后，基于该环境光强度设置对应的亮度级别。
具体地，电子设备在查询漏光映射关系前，可以查询屏幕的亮度级别信息，从而根据亮度级别信息得到屏幕的目标亮度级别。
进一步地，从预设的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的目标漏光量，包括：查询预设的亮度漏光映射关系；亮度漏光映射关系包括屏幕在不同亮度级别显示各种显示内容的情况下分别对应的漏光量；根据目标显示内容和目标亮度级别从亮度漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
其中，亮度漏光映射关系包括屏幕在不同亮度级别显示各种显示内容的情况下分别对应的漏光量，即对于相同的显示内容，屏幕以不同的亮度级别显示该显示内容时，屏幕的漏光量也不同。具体地，电子设备在屏幕的目标亮度级别后，电子设备查询预设的亮度漏光映射关系，从亮度漏光映射关系中，根据目标显示内容和目标亮度级别，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。例如，可以根据目标显示内容的目标内容标识和目标亮度级别得到查询关系式，基于该查询关系式从亮度漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
本实施例中，根据屏幕的目标显示内容和目标亮度级别，从预设的包括屏幕在不同亮度级别显示各种显示内容的情况下分别对应的漏光量的亮度漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，从而根据屏幕的亮度级别和显示内容查询 对应的屏幕漏光量，不需要耗费大量资源计算不同亮度级别和不同显示内容下的屏幕漏光量，有效降低了确定屏幕漏光量的成本，提高了屏幕漏光量的确定效率。
在一个实施例中，亮度漏光映射关系包括漏光映射表；根据目标显示内容和目标亮度级别从亮度漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，包括：根据目标显示内容的目标内容标识和目标亮度级别得到查表参数；按照查表参数在漏光映射表进行查询，得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
其中，亮度漏光映射关系包括漏光映射表，漏光映射表以列表或表格形式记载了屏幕在不同亮度级别显示各种显示内容的情况下分别对应的漏光量。具体地，在查询屏幕漏光量时，电子设备根据目标显示内容的目标内容标识和目标亮度级别得到查表参数。目标内容标识用于标识目标显示内容，如可以为目标显示内容的画面编号、内容名称等。不同的显示内容对应于不同的内容标识，从而可以通过内容标识对电子设备的各种显示内容进行区分。查表参数的形式可以与漏光映射表对应，如可以为(目标内容标识，目标亮度级别)或(目标亮度级别，目标内容标识)，或者也可以为“目标内容标识_目标亮度级别”等各种形式。得到查表参数后，电子设备按照该查表参数在漏光映射表进行查询，根据查询结果得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。例如，可以将查表参数中的目标内容标识和目标亮度级别，分别与漏光映射表中的内容标识和亮度级别进行比较，将匹配一致的内容标识和亮度级别所对应的屏幕漏光量，确定为屏幕在目标亮度级别显示目标显示内容的情况下所对应的屏幕漏光量。
本实施例中，根据目标显示内容的目标内容标识和目标亮度级别得到查表参数，按照查表参数从漏光映射表中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，对于屏幕漏光量的确定简化为一次查表处理，有效降低了屏幕漏光量确定的处理复杂度，降低了确定屏幕漏光量的成本，提高了屏幕漏光量的确定效率。
在一个实施例中，如图7所示，查询屏幕漏光量的处理，即从预设的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，包括操作702至操作706。
操作702，确定目标显示内容的目标内容标识。
其中，目标内容标识用于标识目标显示内容，如可以为目标显示内容的画面编号、内容名称等。不同的显示内容对应于不同的内容标识，从而可以通过内容标识对电子设备的各种显示内容进行区分。
具体地，在查询屏幕漏光量时，电子设备可以确定目标显示内容的目标内容标识，具体可以查询目标显示内容的内容描述信息，从而从该内容描述信息中确定目标显示内容的目标内容标识。
操作704，查询预设的内容漏光映射关系；内容漏光映射关系包括屏幕在显示各种显示内容的情况下分别对应的屏幕漏光量。
其中，内容漏光映射关系包括屏幕在显示各种显示内容的情况下分别对应的屏幕漏光量。屏幕在显示不同的显示内容时，屏幕自身发光的程度不同，从而屏幕因自身发光而产生的屏幕漏光量也不同。内容漏光映射关系可以通过穷举的方法得到，如可以令电子设备屏幕分别显示各显示内容，在屏幕显示各种显示内容时，测量对应的屏幕漏光量，进而建立内容漏光映射关系。
操作706，根据目标内容标识，从内容漏光映射关系中查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
具体地，确定目标显示内容的目标内容标识，且获得预设的内容漏光映射关系后，电子设备基于目标内容标识从内容漏光映射关系中查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。具体实现时，内容漏光映射关系可以包括各种显示内容的内容标识与对应屏幕漏光量之间的映射关系，电子设备可以通过目标内容标识与内容漏光映射关系中的各内容标识进行匹配，将匹配一致的内容标识所对应的屏幕漏光量，确定为屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
本实施例中，根据目标显示内容的目标内容标识，从预设的包括屏幕在显示各种显示内容的情况下分别对应的屏幕漏光量的内容漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，不需要耗费大量资源进行屏幕漏光计算，有效降低了确定屏幕漏光量的成本，提高了确定屏幕漏光量的处理效率。
在一个实施例中，屏幕漏光量确定方法还包括：获取屏幕的校准系数；根据校准系数对屏幕漏光量进行校准处理，得到校准后的屏幕漏光量。
其中，校准系数反映屏幕本身对屏幕漏光量带来的影响，屏幕由于材料、结构或工艺等因素不同，不同屏幕对漏光量有不同的影响，而该影响在屏幕定型时固定，不会有大幅度的改变。例如，屏幕自身对于光的透过率的不同，屏幕本身的形状、大小的不同等。
具体地，电子设备获取屏幕的校准系数，校准系数与屏幕相关，可以包括但不限于包括屏幕对光的透过率、屏幕本身的形状或面积等。校准系数可以由电子设备查询屏幕的属性信息得到，屏幕的属性信息中包括描述了屏幕本身的各种参数，如屏幕的厂商、屏幕对光的透过率、屏幕的形状和大小等。电子设备基于屏幕的校准系数，对查询获得的屏幕漏光量进行校准处理，以校正因屏幕本身因素导致的漏光量干扰，得到校准后的屏幕漏光量。
本实施例中，校准后的屏幕漏光量不仅反映了屏幕显示内容对漏光量的影响，还反映了屏幕本身对漏光量的干扰，校准后的屏幕漏光量能够准确反映屏幕在显示目标显示内容情况下的漏光情况，确保了屏幕漏光量的准确性。
在一个实施例中，获取屏幕的校准系数，包括：确定屏幕的透光参数；基于透光参数确定屏幕的校准系数。
其中，透光参数可以包括屏幕对于光的透过率，屏幕对于光的透过率与屏幕本身的材质、结构和工艺相关，还与屏幕的形状、大小等相关。屏幕对于光的透过率指光透过屏幕的光通量与射到屏幕上的光通量之比，用百分比表示。屏幕对于光的透过率反映了屏幕透过光线的能力，透过率越高，光透过屏幕的越多。
具体地，电子设备确定屏幕的透光参数，透光参数可以从屏幕的属性信息中提取得到，电子设备基于透光参数确定屏幕的校准系数，如可以对透光参数进行映射，得到屏幕的校准系数。本实施例中，基于屏幕的透光参数确定屏幕的校准系数，从而根据屏幕的透光能力确定校准系数对屏幕漏光量进行校准处理，可以校正因屏幕本身因素导致的漏光量干扰，得到提高屏幕漏光量的准确性。
在一个实施例中，漏光映射关系是根据标准屏幕在显示各显示内容的情况下分别对应的屏幕漏光量确定的。
其中，各显示内容为电子设备的屏幕所有能够进行展示的画面，不同的电子设备对应有不同展示的画面，而电子设备在不同的场景下也可能有不同展示的画面。如智能手机、笔记本电脑等电子设备，其屏幕能够展示的画面数量多，不受限制；而对于智能手表、智能手环等可穿戴电子设备，其屏幕展示的画面数量有限，如手表可以展示表盘、电话、音乐、邮件等不同的有限数量的画面。标准屏幕为展示显示内容的画面的电子设备的屏幕，标准屏幕与当前确定漏光量的屏幕可以为同一类型的屏幕，如均作为某一款智能手环的屏幕等。标准屏幕可以包括多个相同类型的电子设备的屏幕，从而可以基于多个相同类型电子设备的屏幕，构建漏光映射关系。例如，电子设备为一款智能手表A，则标准屏幕可以为多个智能手表A的屏幕，根据各个智能手表A的标准屏幕显示各显示内容，从而确定屏幕漏光量后构建智能手表A对应的漏光映射关系，在确定电子设备为智能手表A的屏幕漏光量时，可以基于智能手表A对应的漏光映射关系直接查询到在显示目标显示内容时所对应的屏幕漏光量。
具体地，电子设备确定屏幕的各显示内容时，可以获取电子设备的画面描述信息，画面描述信息记载了描述电子设备屏幕显示的各个画面的内容，如描述了智能手表在显示表盘时，屏幕具体显示的画面。电子设备对画面描述信息遍历进行分析，得到屏幕的各显示内容。例如，可以将不同功能场景对应的画面，划分为不同的显示内容；也可以将不同界面对应画面划分为不同的显示内容等。
确定屏幕的各显示内容后，确定电子设备的标准屏幕在显示各显示内容的情况下分别对应的屏幕漏光量。具体可以由电子设备控制标准屏幕分别显示各显示内容，并在标准屏幕分别显示各显示内容时，测量相应的屏幕漏光量。标准屏幕与当前确定漏光量的屏幕属于同一类型电子设备的相同类型屏幕，电子设备建立各显示内容分别与对应的屏幕漏光量之间的映射关系，得到漏光映射关系。例如，电子设备可以确定各显示内容对应的内容标识，并建立各显示内容对应的内容标识与对应的屏幕漏光量之间的映射关系，得到漏光映射关系，从而可以通过目标显示内容的目标内容标识，在漏光映射关系中查询得到屏幕在显示目标显示内容的情况下的屏幕漏光量。
本实施例中，根据屏幕的各种显示内容，及标准屏幕在显示各种显示内容的情况下分别对应的屏幕漏光量，建立屏幕的漏光映射关系，从而根据标准屏幕在显示各显示内容的情况下分别对应的屏幕漏光量确定漏光映射关系，可以在确定屏幕的目标显示内容后，从漏光映射关系中直接查询得到对应的屏幕漏光量，不需要耗费大量资源进行屏幕漏光计算，有效降低了确定屏幕漏光量的成本，提高了确定屏幕漏光量的处理效率。
在一个实施例中，本申请还提供一种应用场景，该应用场景应用上述的屏幕漏光量确定方法。具体地，该屏幕漏光量确定方法在该应用场景的应用如下：
屏幕漏光量确定方法应用于智能手表或智能手环等显示画面数量有限的电子设备中，通过穷举的方法预先设定好每个显示画面的屏幕漏光量，并保存在系统内，当需要使用时直接通过查表的方式获取当前屏幕漏光量，从而省去截屏和计算的操作，减少电量消耗，并且漏光量不需要经过公式拟合后反推计算，可以更加准确的得到屏幕漏光量。
具体地，屏幕的漏光量主要由三个因素决定：一为屏幕显示内容，不同的显示内容，产生的漏光量不同；二为屏幕的亮度等级，不同的亮度等级下，产生的漏光量不同；三为屏幕自身的透过率，这个在屏幕模组定型时就已经基本固定，只会有小范围的分布波动，不会有大幅度的变化。对于屏幕显示内容和屏幕的亮度等级，可以组成一个漏光量的关系式函数，即漏光量L_data≈f(画面，亮度)，假设屏幕亮度一共256等级(0～255)，而电子设备屏幕画面一共有n个，那么可以预先构建漏光映射表格，如下表1所示。
表1
Figure PCTCN2022075534-appb-000001
对于屏幕自身的透过率，由于屏幕透过率虽然有小辐度的波动，但是整体是成线性变化的，所以，可以在漏光量L_data数据基础上乘以一个校准系数，即可完成校准。假设校准系数为cal,那么可以得出屏幕漏光L_data的关系式为L_data＝f(画面，亮度)*cal，由此关系式，只需要确定当时显示画面编号、亮度等级和校准系数，即可以准确的得到当时画面的漏光量L_data。
本实施例中，通过查表法获取当前画面的屏幕漏光量，从而省去截屏和计算操作，减少能量消耗并提高漏光计算准确性，提升用户体验。
图8为一个实施例中屏幕亮度调节方法的流程图。本实施例中的屏幕亮度调节方法，以运行于图1中的电子设备上为例进行描述。如图8所示，屏幕漏光量确定方法包括操作802 至操作808。
操作802，获取环境光感量；
操作804，确定屏幕在显示目标显示内容情况下所对应的屏幕漏光量；所述屏幕漏光量通过从预设的漏光映射关系中查询得到；
操作806，根据所述环境光感量和所述屏幕漏光量得到实际光感量；
操作808，基于所述实际光感量对所述屏幕进行亮度调节。
其中，环境光感量表征了电子设备屏幕当前的环境光强度，具体可以由电子设备通过设置的环境光传感器感知得到。环境光传感器可以感知周围光线情况，并告知处理芯片自动调节显示器背光亮度，降低产品的功耗。环境光传感器为热电效应原理，感应元件采用绕线电镀式多接点热电堆，其表面涂有高吸收率的黑色涂层，热接点在感应面上，而冷结点则位于机体内，冷热接点产生温差电势，在线性范围内，输出信号和太阳辐照度成正比。为减小温度的影响则配有温度补偿线路，为了防止环境对其性能的影响，则用两层石英玻璃罩，罩是经过精密的光学冷加工磨制而成的。
漏光映射关系包括屏幕在显示各种显示内容的情况下，分别对应的屏幕漏光量。具体地，可以预先确定电子设备需要显示的各种显示内容，并确定各种显示内容对应的屏幕漏光量，如可以通过控制电子设备的屏幕在显示各种显示内容时，测量得到电子设备的屏幕在显示各种显示内容时分别对应的屏幕漏光量。根据电子设备需要显示的各种显示内容及对应的屏幕漏光量，构建得到漏光映射关系。屏幕在显示内容时，屏幕自身会发光，而环境光传感器在感知环境光时，会检测到屏幕自身发光而产生的漏光，从而导致环境光感量存在一定误差。实际光感量表征了去除屏幕漏光量所引入的误差的实际环境光强度。
具体地，电子设备在进行屏幕亮度调节处理时，电子设备获取环境光感量，环境光感量由电子设备的环境光传感器感知得到。电子设备确定屏幕在显示目标显示内容情况下所对应的屏幕漏光量；屏幕漏光量通过从预设的漏光映射关系中查询得到。如可以将目标显示内容的目标内容标识与漏光映射关系中各种显示内容的内容标识进行匹配，将与目标内容标识匹配一致的内容标识对应的屏幕漏光量，确定为屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
确定屏幕在显示目标显示内容情况下所对应的屏幕漏光量后，电子设备根据环境光感量和屏幕漏光量得到实际光感量，如根据环境光感量和屏幕漏光量的差值得到实际光感量，并基于该实际光感量对屏幕进行亮度调节，如调亮屏幕或调暗屏幕。
本实施例中，通过从预设的包括屏幕在显示各种显示内容的情况下，分别对应的屏幕漏光量的漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，可以在确定屏幕的目标显示内容后，从预设的漏光映射关系中直接查询得到对应的屏幕漏光量，不需要耗费大量资源进行屏幕漏光计算，有效降低了确定屏幕漏光量的成本，提高了确定屏幕漏光量的处理效率。进一步利用屏幕漏光量根据环境光感量确定实际光感量，并基于实际光感量进行屏幕亮度调节，有效降低了屏幕亮度调节的成本，提高了屏幕亮度调节的处理效率。
在一个实施例中，确定屏幕在显示目标显示内容情况下所对应的屏幕漏光量，包括：确定屏幕的目标亮度级别；查询预设的亮度漏光映射关系；亮度漏光映射关系包括屏幕在不同亮度级别显示各种显示内容的情况下分别对应的漏光量；根据目标显示内容和目标亮度级别从亮度漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
其中，目标亮度级别表征电子设备的屏幕在进行显示时的亮度大小，目标亮度级别可以由用户设定，如用户在电子设备的显示亮度界面，通过亮度调节控件设置屏幕的目标亮度级别。电子设备可以查询屏幕的亮度级别信息，从而根据亮度级别信息得到屏幕的目标亮度级别。亮度漏光映射关系包括屏幕在不同亮度级别显示各种显示内容的情况下分别对应的漏光量，即对于相同的显示内容，屏幕以不同的亮度级别显示该显示内容时，屏幕的漏光量也不同。具体地，电子设备在屏幕的目标亮度级别后，电子设备查询预设的亮度漏光映射关系， 从亮度漏光映射关系中，根据目标显示内容和目标亮度级别，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。例如，可以根据目标显示内容的目标内容标识和目标亮度级别得到查询关系式，基于该查询关系式从亮度漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。

具体地，在查询屏幕漏光量时，电子设备可以确定目标显示内容的目标内容标识，具体可以查询目标显示内容的内容描述信息，从而从该内容描述信息中确定目标显示内容的目标内容标识。确定目标显示内容的目标内容标识，且获得预设的内容漏光映射关系后，电子设备基于目标内容标识从内容漏光映射关系中查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。具体实现时，内容漏光映射关系可以包括各种显示内容的内容标识与对应屏幕漏光量之间的映射关系，电子设备可以通过目标内容标识与内容漏光映射关系中的各内容标识进行匹配，将匹配一致的内容标识所对应的屏幕漏光量，确定为屏幕在显示目标显示内容的情况下所对应的屏幕漏光量。
本实施例中，根据目标显示内容的目标内容标识，从预设的包括屏幕在显示各种显示内 容的情况下分别对应的屏幕漏光量的内容漏光映射关系中，查询得到屏幕在显示目标显示内容的情况下所对应的屏幕漏光量，不需要耗费大量资源进行屏幕漏光计算，有效降低了确定屏幕漏光量的成本，提高了确定屏幕漏光量的处理效率。
在一个实施例中，在根据环境光感量和屏幕漏光量得到实际光感量之前，还包括：获取屏幕的校准系数；根据校准系数对屏幕漏光量进行校准处理，得到校准后的屏幕漏光量。
其中，校准系数反映屏幕本身对屏幕漏光量带来的影响，屏幕由于材料、结构或工艺等因素不同，不同屏幕对漏光量有不同的影响，而该影响在屏幕定型时固定，不会有大幅度的改变。具体地，电子设备获取屏幕的校准系数，校准系数与屏幕相关，可以包括但不限于包括屏幕对光的透过率、屏幕本身的形状或面积等。校准系数可以由电子设备查询屏幕的属性信息得到，屏幕的属性信息中包括描述了屏幕本身的各种参数，如屏幕的厂商、屏幕对光的透过率、屏幕的形状和大小等。电子设备基于屏幕的校准系数，对查询获得的屏幕漏光量进行校准处理，以校正因屏幕本身因素导致的漏光量干扰，得到校准后的屏幕漏光量。
进一步地，根据环境光感量和屏幕漏光量得到实际光感量，包括：根据环境光感量和校准后的屏幕漏光量得到实际光感量。
得到校准后的屏幕漏光量后，电子设备根据环境光感量和校准后的屏幕漏光量得到实际光感量，从而提高了实际光感量的准确性，确保了亮度调节的效果。
本实施例中，校准后的屏幕漏光量不仅反映了屏幕显示内容对漏光量的影响，还反映了屏幕本身对漏光量的干扰，校准后的屏幕漏光量能够准确反映屏幕在显示目标显示内容情况下的漏光情况，确保了屏幕漏光量的准确性，从而提高了实际光感量的准确性，确保了亮度调节的效果。
在一个实施例中，获取屏幕的校准系数，包括：确定屏幕的透光参数；基于透光参数确定屏幕的校准系数。
其中，透光参数可以包括屏幕对于光的透过率，屏幕对于光的透过率与屏幕本身的材质、结构和工艺相关，还与屏幕的形状、大小等相关。具体地，电子设备确定屏幕的透光参数，透光参数可以从屏幕的属性信息中提取得到，电子设备基于透光参数确定屏幕的校准系数，如可以对透光参数进行映射，得到屏幕的校准系数。本实施例中，基于屏幕的透光参数确定屏幕的校准系数，从而根据屏幕的透光能力确定校准系数对屏幕漏光量进行校准处理，可以校正因屏幕本身因素导致的漏光量干扰，得到提高屏幕漏光量的准确性。
在一个实施例中，漏光映射关系是根据标准屏幕在显示各显示内容的情况下分别对应的屏幕漏光量确定的。
其中，各显示内容为电子设备的屏幕所有能够进行展示的画面，不同的电子设备对应有不同展示的画面，而电子设备在不同的场景下也可能有不同展示的画面。具体地，电子设备确定屏幕的各显示内容时，可以获取电子设备的画面描述信息，画面描述信息记载了描述电子设备屏幕显示的各个画面的内容，如描述了智能手表在显示表盘时，屏幕具体显示的画面。电子设备对画面描述信息遍历进行分析，得到屏幕的各显示内容。例如，可以将不同功能场景对应的画面，划分为不同的显示内容；也可以将不同界面对应画面划分为不同的显示内容等。
确定屏幕的各显示内容后，电子设备确定标准屏幕在显示各显示内容的情况下分别对应的屏幕漏光量。具体可以由电子设备控制标准屏幕分别显示各显示内容，并在标准屏幕分别显示各显示内容时，测量相应的屏幕漏光量。电子设备建立各显示内容分别与对应的屏幕漏光量之间的映射关系，得到漏光映射关系。例如，电子设备可以确定各显示内容对应的内容标识，并建立各显示内容对应的内容标识与对应的屏幕漏光量之间的映射关系，得到漏光映射关系，从而可以通过目标显示内容的目标内容标识，在漏光映射关系中查询得到屏幕在显示目标显示内容的情况下的屏幕漏光量。
本实施例中，根据屏幕的各种显示内容，及标准屏幕在显示各种显示内容的情况下分别对应的屏幕漏光量，建立屏幕的漏光映射关系，从而根据标准屏幕在显示各显示内容的情况 下分别对应的屏幕漏光量确定漏光映射关系，可以在确定屏幕的目标显示内容后，从漏光映射关系中直接查询得到对应的屏幕漏光量，不需要耗费大量资源进行屏幕漏光计算，有效降低了确定屏幕漏光量的成本，提高了确定屏幕漏光量的处理效率。
