具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
在附图中，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。所描述的实施例是本公开一部分实施例，而不是全部的实施例。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。下面结合附图对本公开的实施例进行详细说明。
本公开实施例提供的调节屏幕亮度的方法，可以应用于终端自动调节屏幕亮度的场景。其中，本公开实施例提供的调节屏幕亮度的方法可以应用于手机、平板电脑、电视等具有显示功能的设备。
随着终端和网络技术的发展，越来越多的用户都有在终端上观看视频、打游戏以及阅读小说的习惯。由于终端的便携性，用户使用终端的场景也不固定。用户在不同的场景使用终端时，就需要随着场景亮度的不同，而不断的调解屏幕亮度来使得用户获得最好的显示体验。
相关技术中都是在用户前期手动调解屏幕亮度后得到的屏幕亮度历史数据的基础上，实现终端自动调整屏幕亮度调节策略。其中，较为智能的调节屏幕亮度的方法则是将当前的环境光强和显示场景等外界因素考虑进去，从而多方位的调节屏幕亮度。相关技术中需要用户自身使用调整后的屏幕亮度的大量历史数据作为参考依据，才能设计出合理的屏幕亮度调节策略。但是要获取大量的前期用户手动调整后的屏幕亮度历史数据需要花费大量的时间，导致形成屏幕亮度调节策略的时间严重滞后。而且用户在最初运行终端设备的时候，终端中没有存储任何屏幕亮度历史数据作为参考。这会导致用户在使用终端初期，产生不良的体验。
有鉴于此，本公开提供了一种调节屏幕亮度的方法，获取第一用户画像，确定与第一用户画像匹配的第二用户画像，并获取第二用户画像使用的屏幕亮度调节策略。进一步的，基于第二用户画像使用的屏幕亮度调节策略，确定第一用户画像的屏幕亮度调节策略。基于此，即使在初期可供终端参考的屏幕亮度调节策略不足的情况下时，终端也可以基于已有的屏幕亮度调节策略对屏幕亮度进行自动调节，同时，提升用户的体验感。
在下述公开实施例中，用户画像可以为包括用户属性、用户偏好、生活习惯、用户行为、职业等至少一项标签信息而抽象出来的标签化用户模型。
本公开一些可能的实施例中，可以将进行终端屏幕亮度调节的用户称为第一用户，例如，使用新终端的用户。将已进行过屏幕亮度调节(已有屏幕亮度调节配置)的用户称为第二用户。将进行终端屏幕亮度调节的第一用户的用户画像称为第一用户画像，将已有屏幕亮度调节配置的第二用户的用户画像称为第二用户画像。
图1是根据一示例性实施例示出的一种调节屏幕亮度的方法的流程图，如图1所示，调节屏幕亮度的方法用于终端中，包括以下步骤。
在步骤S11中，获取第一用户画像。
本公开一些可能的实施例中，可以在用户(即第一用户)进行屏幕亮度设置操作时，获取终端用户的用户画像(即第一用户画像)。比如，可以是在终端首次接收到进行亮度调节的用户输入(即终端被首次启动进行屏幕亮度调节)的情况下采集第一用户画像；又比如，可以是在终端预设配置开关被触发的情况下采集第一用户画像，该预设配置开关可以是终端上预先设置的用于启用本公开调节屏幕亮度方法对应功能的配置项开关(虚拟开关和/或物理开关)。在本公开一些可能的实施例中，可以在终端用户(即第一用户)首次使用本终端时，获取终端用户的用户画像(即第一用户画像)。比如，可以是在终端在出厂配置状态下首次启动(包括终端首次启动以及恢复出厂设置后的首次启动)的情况下采集第一用户画像。这里，在终端恢复出厂设置后可以适应理解终端用户首次使用本终端。
示例地，第一用户画像可以为本终端使用用户的用户画像，或者可以为本终端注册用户的用户画像。在通常场景下本终端使用用户和本终端注册用户一般为同一用户。
在本公开一些可能的实施例中，获取第一用户画像的步骤可以包括：显示提示信息。采集基于用户画像信息项所输入的画像信息，得到第一用户画像。其中，提示信息中包括用于提示用户输入用户画像信息项。
可以理解的是，提示信息至少包括用户姓名、用户性别、用户年龄、用户所在地区、用户职业，在本公开实施例中不对提示信息作具体限定。
在本公开一些可能的实施例中，在终端被首次启动进行屏幕亮度调节时，或者，终端在出厂配置状态下首次启动时，或者，终端预设配置开关被触发时，显示提示信息。示例地，在用户初次运行终端时，屏幕上显示开机设置界面，并显示需要用户进行画像采集的提示信息。其中，终端厂商可以自行设定用户画像包括的个人信息。在一些可能的实施例中，考虑到用户画像涉及到用户的个人隐私，在终端进行采集个人信息之前，需要向用户进行详细的说明，并保护用户的个人隐私。如果用户拒绝提供个人信息，则需要向用户说明终端无法开启本公开调节屏幕亮度方法对应功能。
在本公开实施例中，终端A采集到的用户画像信息包括，姓名：张三、年龄：34、性别：男、职业：厨师、地区：北京......终端B采集到的用户画像信息包括，姓名：李四、年龄：23、性别：男、职业：学生、地区：北京......终端C采集到的用户画像信息包括，姓名：王五、年龄：56、性别：女、职业：教师、地区：北京.....。本公开实施例通过用户输入画像信息的方式，得到对应使用终端的用户的用户画像，例如，获取第一用户的第一用户画像。
在本公开中，显示提示信息，采集用户基于用户画像信息项所输入的画像信息，得到目标用户画像。通过本公开，终端采集得到用户的用户画像，为后续终端自动调节屏幕亮度起到辅助作用。
在步骤S12中，确定与第一用户画像匹配的第二用户画像，并获取第二用户画像使用的屏幕亮度调节策略。
在本公开一些可能的实施例中，屏幕亮度调节策略包括屏幕亮度调节曲线。其中，屏幕亮度调节曲线用于表征需要调节的亮度对应的屏幕亮度参数。屏幕亮度调节曲线也称为屏幕亮度曲线，是一种屏幕亮度参数随设置的自变量变化的曲线。
在本公开实施例中，屏幕亮度调节策略可以以数据包的形式存储在服务器和终端中。屏幕亮度调节策略的数据包中可以包括：终端应用场景、用户使用时间、当前所处环境亮度、用户手动调节亮度等可以影响屏幕亮度调节策略的因素，与上述因素确定的屏幕亮度 参数之间对应关系。例如，夜间11点至12点，用户在终端上浏览视频，此时，屏幕亮度调节策略设定为30％。白天11点至12点，用户在终端上阅读小说，此时，屏幕亮度调节策略设定为80％。
在步骤S13中，基于第二用户画像使用的屏幕亮度调节策略，确定第一用户画像的屏幕亮度调节策略。
在本公开中，获取第一用户画像，确定与第一用户画像匹配的第二用户画像，并获取第二用户画像使用的屏幕亮度调节策略。进一步的，基于第二用户画像使用的屏幕亮度调节策略，确定第一用户画像的屏幕亮度调节策略。通过本公开，可以为终端用户适配已有的屏幕亮度调节策略，即使在初期可供终端参考的屏幕亮度调节策略不足的情况下时，终端也可以基于已有的屏幕亮度策略对屏幕亮度进行自动调节，能够缩短终端与用户之间的磨合期，提升用户的体验感。
在下述实施例公开中，将详细描述如何通过第一用户画像确定第二用户画像使用的屏幕亮度调节策略。
图2a是根据一示例性实施例示出的一种确定与第一用户画像匹配的第二用户画像的流程图，如图2a所示，确定与第一用户画像匹配的第二用户画像，包括以下步骤。
在步骤S22中，确定第一用户画像与多组用户画像中每一组用户画像之间的相似度，得到多个相似度。
在步骤S23中，将多个相似度中最大相似度对应的用户画像，作为第一用户画像匹配的第二用户画像。
在本公开实施例中，在获取到第一用户的第一用户画像之后，计算第一用户的第一用户画像与老用户的用户画像之间的相似度。其中，计算第一用户的第一用户画像与老用户的用户画像之间的相似度的度量方法包括：欧式距离，余弦相似度，皮尔顿相关系数等等。本公开实施例中，不对相似度度量方法进行具体限定。本公开一些可能的实施例中，为便于相似度运算，可以对用户画面的各个标签按照预设编号规则分别进行编号，然后通过编号向量的形式进行存储用户画像。
在本公开一些可能的实施例中，终端获取得到的用户画像可以包括姓名、年龄、性别、职业和地区五方面的个人信息。示例地，针对姓名信息，可以基于姓氏进行编号，如张姓编号可以为1，李姓编号可以为2，其余姓氏编号以此类推；又如，姓氏为Smith的编号可以为11，姓氏为Miller的编号可以为12，姓氏为Johnson的编号可以为13，其余姓氏编号以此类推。针对年龄信息，0-10岁编号可以为1，11-20岁编号可以为2，其余年龄范围以此类推。针对性别信息，男性的编号可以为1，女性的编号可以为2，第三性别的编号 可以为3。针对职业信息，科学家编号可以为1，工程师编号可以为2，其余职业编号以此类推。针对地区信息，北京编号可以为1，上海编号可以为2，其余地区编号以此类推。
在本公开实施例中，终端将采集得到的用户画像通过编号向量的形式进行存储。例如，用户张三的用户画像的用户画像信息项如下，姓名：张三、年龄：34、性别：男、职业：厨师、地区：北京，则在终端中用户画像可以以编号向量存储为[1，4，1，5，1]。第一用户李四的用户画像的用户画像信息项如下，姓名：李四、年龄：23、性别：男、职业：学生、地区：北京，则在终端中用户画像可以以编号向量存储为[2，3，1，8，1]。第一用户王五的用户画像的用户画像信息项如下，姓名：王五、年龄：56、性别：女、职业：教师、地区：北京，则在终端中用户画像可以以编号向量存储为[3，4，2，3，1]。
在本公开实施例中，基于终端获取得到的第一用户画像，以及服务器中已经存在的第二用户画像，采用余弦相似度方法，进行相似度计算。根据相似度(similarity)公式
Figure PCTCN2022098965-appb-000001
计算第一用户的编号向量与第二用户的编号向量之间的相似度。如果similarity的值为1，则说明第一用户的画像信息与第二用户的画像信息完全匹配，终端会将该第二用户的屏幕亮度调节策略进行存储，并使用该屏幕亮度调节策略作为初始屏幕亮度调节策略。如果similarity的值为-1，则说明新用户的画像信息与第二用户的画像信息完全不匹配，终端会和其他在服务器中的第二用户画像信息重新进行匹配，并选择相似度最高的第二用户的屏幕亮度调节策略作为该终端初始屏幕亮度调节策略。
可以理解的是，上述公开实施例中提及到的选择哪种相似度度量方法，用户画像包括哪些个人信息，每一项个人信息的编号如何设置，以及是否需要配置不同的权重，都是由终端厂商自行定义，本公开不做具体限定。
在本公开中，确定第一用户画像与多组用户画像中每一组用户画像之间的相似度，得到多个相似度。将多个相似度中最大相似度对应的用户画像，作为第一用户画像匹配的第二用户画像。通过本公开，在用户刚拿到一台新终端时，避免了长时间搜集用户在不同环境下使用终端时的屏幕亮度，减少了时间成本，同时为新用户前期提供了良好的使用体验。
图2b是根据一示例性实施例示出的一种确定与第一用户画像匹配的第二用户画像的流程图，如图2b所示，包括以下步骤。
图2b包含步骤S21、S22和S23。其中，S22和S23与图2a中S22和S23的实施方式类似，因此本公开不再对S22和S23做进一步解释。
在步骤S21中，确定多组用户画像。
其中，多组用户画像为基于不同屏幕调节策略进行屏幕亮度调节的多个不同用户画像。
在本公开中，确定多组用户画像的步骤包括：确定终端的当前使用环境；确定符合当前使用环境的多组用户画像。终端的当前使用环境可以包括当前位置信息，如当前位置所在地区和/或当前位置所在时区等；终端的当前使用环境可以包括当前位置的天气情况。
在本公开实施例中，例如，确定用户使用终端的所处地区，比如：北京、上海、广州等等，根据地区确定屏幕亮度调节策略符合当前用户所处地区的多组用户画像。其中，当前使用环境还可以是天气，例如，晴天的时候终端屏幕亮度就会比较高，阴天的时候终端屏幕亮度就会比较低。
在本公开中，通过对比不同用户之间的用户画像相似度，确定当前第一用户的屏幕亮度调节策略。其中的依据为：若不同用户之间的用户画像相似度最大，则说明第一用户的使用行为与相似度大的第二用户的使用行为最接近，可以将第二用户设置的屏幕亮度调节策略作为第一用户前期参考的屏幕亮度调节策略，即，第一用户的亮度使用习惯可以在前期先参考相似的用户群体的亮度使用习惯。基于此，本公开提供的一种调节屏幕亮度的方法，可以解决用户使用初期可供参考的屏幕亮度调节策略不足的问题，也能缩短形成最佳自动亮度曲线所花费的时间，同时提升用户使用终端时的体验感。
图3是根据一示例性实施例示出的一种调节屏幕亮度的方法的流程图，如图3所示，调节屏幕亮度的方法用于终端中，包括以下步骤。
在步骤S31中，监测用户在预定时间段内对终端所进行屏幕亮度调节所对应的屏幕亮度调节参数。
在步骤S32中，基于屏幕亮度调节参数，更新第一用户画像的屏幕亮度调节策略。
在本公开实施例中，在预定时间段内，基于用户调节后的屏幕亮度，调整屏幕亮度调节策略。例如，在终端中已经存在匹配后的屏幕亮度调节策略，基于新用户个人的使用习惯及使用场景，对自动导入的屏幕亮度调节策略，采用传统技术进行微调及优化。例如，结合环境光亮度，用户手调亮度，使用的应用程序和使用时间来进行自动亮度调节。如果用户在某个特定的时间，特定的环境光亮度和特定的应用程序上多次手动调整过自动亮度，那么这个应用程序的推荐自动屏幕亮度调节策略会做出调整，在接近这个时间和环境光亮度的屏幕亮度调节策略会调整为用户手动调节后屏幕亮度调节策略的平均值。例如，用户A有每天晚上在黑暗的情况下使用短视频应用程序的习惯，若第一天和第二天用户都认为屏幕亮度太低而调高了亮度，那么在第三天晚上且黑暗的环境下用户再使用短视频应用程序时，屏幕亮度将变为前两次用户手调后的屏幕亮度调节策略的平均值，实现自动提高屏幕亮度。
在本公开中，监测用户在预定时间段内对终端所进行的屏幕亮度调节参数，基于屏幕 亮度调节参数，更新第一用户画像的屏幕亮度调节策略。通过本公开，在终端已经存在一个初始屏幕亮度调节策略的情况下，还可以基于后期用户对屏幕亮度参数的调整，更新初始屏幕亮度调节策略，使该策略更加的适合用户使用。
图4示出了一种终端自动调节屏幕亮度的示意图。如图4所示，第一用户使用终端。在第一用户初次运行终端时，提示第一用户填写个人画像信息。若第一用户选择拒绝采集个人画像信息，则提示第一用户前期需要手动对屏幕亮度进行调节。若第一用户填写完成个人画像信息(第一用户画像信息)，则终端对第一用户画像信息进行解析，并将获取得到的第一用户画像信息按编号向量的形式进行存储，例如，第一用户画像信息可以包括但不限于姓名、性别、年龄等。终端采用相似度度量方法，例如，欧式距离，余弦相似度等，依次计算第一用户的编号向量与服务器中已经存储的第二用户的编号向量之间的相似度，并选取相似度最高的第二用户对应的屏幕亮度调节策略作为第一用户终端的初始屏幕亮度调节策略，导入至终端中进行使用。根据第一用户的使用习惯，对初始屏幕亮度调节策略进行优化，从而得到适合第一用户个人的屏幕亮度调节策略。基于此，前期终端通过获取用户画像，为第一用户匹配相似度最高的第二用户，将第二用户的屏幕亮度调节策略发送至第一用户的终端中，提升第一用户在前期的使用体验。由于发送至第一用户终端的屏幕亮度调节策略与第一用户的预期较为贴合，所以后期只需花费少量的时间，根据第一用户的使用习惯进行微调优化，就可以得到符合第一用户需求的屏幕亮度调节策略，减少了时间成本。
基于相同的构思，本公开实施例还提供一种调节屏幕亮度的装置。
可以理解的是，本公开实施例提供的调节屏幕亮度的装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。

获取单元101，用于获取第一用户画像；处理单元102，用于确定与第一用户画像匹配的第二用户画像，并获取第二用户画像使用的屏幕亮度调节策略；调节单元103，用于基于第二用户画像使用的屏幕亮度调节策略，确定第一用户画像的屏幕亮度调节策略。
一种实施方式中，处理单元102采用如下方式确定与第一用户画像匹配的第二用户画 像：确定第一用户画像与多组用户画像中每一组用户画像之间的相似度，得到多个相似度；将多个相似度中最大相似度对应的用户画像，作为第一用户画像匹配的第二用户画像。
