具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
当本发明实施例提及“第一”、“第二”等序数词时，除非根据上下文确定表达顺序之意，应当理解为仅仅起区分的作用。
本发明实施例中所涉及的终端，包括可穿戴设备、手机、平板电脑、笔记本电脑、UMPC(Ultra-mobile Personal Computer，超级移动个人计算机)、上网本、PDA(Personal Digital Assistant，个人数字助理)等，下面以可穿戴设备为例，对本发明的各个实施例进行介绍。
可穿戴设备常用的产品形态包括以手腕为支撑的watch类(包括手表、手环、腕带等)，以脚为支撑的shoes类(包括鞋、袜子或者将来的其他腿上佩戴产品)，以头部为支撑的Glass类(包括眼镜、头盔、头带等)，以及智能服装、书包、拐杖、配饰等，可以理解的，只要终端包括显示屏，具备用户可视的显示功能，均可以采用本发明实施例所提供的环境光检测方法。
图1为本发明实施例可穿戴设备的电路示意图。如图1所示，可穿戴设备100包括处理器110、屏幕120、环境光传感器130等部件。可穿戴设备100还可以包括存储器140、输入单元150、以及电源160等部件。本领域技术人员可以理解，图1中示出的可穿戴设备100的结构并不构成对可穿戴设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
下面结合图1对可穿戴设备100的各个构成部件进行具体的介绍：
处理器110是可穿戴设备100的控制中心，利用各种接口和线路连接整个可穿戴设备100的各个部分，通过运行或执行存储在存储器140内的软件程序和/或模块，以及调用存储在存储器140内的数据，执行可穿戴设备100的各种功能和处理数据，从而对可穿戴设备100进行整体监控。处理器110可以为应用处理器，也可以为基带处理器，还可以是集成的基带处理器和应用处理器，或处理器包括基带处理器和应用处理器。其中，应用处理器主要处理操作系统、用户界面和应用程序等，基带处理器负责数据处理与存储，主要组件为数字信号处理器、微控制器、内存等单元，主要的功能为基带编码/译码、声音编码及语音编码等，随着技术的发展，基带处理器还可以提供多媒体功能以及用于多媒体显示器、图像传感器和音频设备的相关接口。
屏幕120可用于显示由用户输入的信息或提供给用户的信息或可以显示可穿戴设备100的各种菜单。屏幕120可包括显示面板121，可选的，可以采用液晶显示屏(Liquid Crystal Display，简称LCD)、有机发光二极管(Organic Light-Emitting Diode，简称OLED)等形式来配置显示面板121。
进一步的，作为输入单元150的触摸面板151可覆盖屏幕120，当触摸面板151检测到在其上或附近的触摸操作后，可以通过Mobile Industry Processor Interface(简称MIPI接口)传送给处理器110以确定触摸事件的类型，随后处理器110根据触摸事件的类型在屏幕120上提供相应的视觉输出。虽然在图1中，触摸面板151与屏幕120是作为两个独立的部件来实现可穿戴设备100的输入和显示功能，但是在某些实施例中，可以将触摸面板151与屏幕120集成而实现可穿戴设备100的输入和显示功能。
环境光传感器130，可以检测环境光的亮度，可穿戴设备100可根据环境光的亮度来调节显示面板141的亮度。进一步的，可穿戴设备100中还可以包括其他传感器，例如：光传感器、运动传感器、密度传感器、指纹传感器等。具体地，光传感器可包括除环境光传感器以外的传感器，如接近传感器，可以检测是否有物体靠近或接触可穿戴设备100，可在可穿戴设备100 移动到耳边时，可穿戴设备100关闭显示面板141和/或背光。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别可穿戴设备100姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等。密度传感器可以检测到可穿戴设备100所接触的物质的密度。指纹采集传感器用于采集用户输入的指纹。可穿戴设备100还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
存储器140可用于存储软件程序或模块，处理器110通过运行存储在存储器140的软件程序或模块，从而执行可穿戴设备100的各种功能应用以及数据处理。存储器140可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据可穿戴设备100的使用所创建的数据(比如音频数据、图像数据等)等。此外，存储器140可以为高速随机存取存储器，还可以为非易失性存储器，例如至少一个磁盘存储器、闪存器件、或其他易失性固态存储器。
可穿戴设备100还包括给各个部件供电的电源160(比如电池)，优选的，电源可以通过电源管理系统与处理器110逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
可穿戴设备100还可以包括RF(radio frequency，射频)电路170、音频电路180、Wi-Fi(wireless fidelity，无线保真)模块190等，在此不再赘述。
通常，可穿戴设备在未被使用时，处于待机状态，屏幕无显示；而当用户需要浏览屏幕上显示的内容时，会触发终端点亮屏幕。在用户持续浏览内容的过程中，可穿戴设备移动后，可能会导致可穿戴设备所处的外界光，即环境光亮度发生了变化，为了让用户更好的浏览屏幕内容，可穿戴设备会根据环境光传感器对环境光亮度的检测结果调整屏幕亮度。
第一实施例：
以有机发光二极管OLED屏幕为例，图2为本发明实施例提供的一种可穿戴设备的结构示意图。如图2所示，屏幕120具有上表面1201、下表面1202，黑胶层1203位于屏幕的下表面1202，环境光传感器130设置于黑胶层1203的镂空区域1204。环境光传感器130可以置于FPC软板140上。环境光传感器的感光元件1301朝向屏幕120并位于屏幕120的下表面1202，环境光传感器130和屏幕120可以分别通过FPC与处理器110相连。
可以理解的是，本实施例中的黑胶层1203可以根据其具有的不同功能而具有不同的名称，例如，具有遮光的作用的遮光黑胶层、具有缓冲作用的缓冲黑胶层、具有缓冲和遮光的作用的缓冲遮光黑胶层等。黑胶层位于屏幕的下表面，可以是贴合，也可以直接放置，即本实施例中的黑胶层并不一定具有粘性，在此不做限定。
当环境光传感器130检测环境光亮度时，检测到的环境光亮度为穿透屏幕透射至环境光传感器130的感光元件1301上的外界的环境光亮度。因此，屏幕显示时，环境光传感器130会受到屏幕自发光或屏幕背光的影响，使得环境光传感器130的检测结果不仅包括了可穿戴设备所处的环境光的亮度，还包括了屏幕自发光或背光的亮度。
为了获得更准确的可穿戴设备所处的环境光的亮度，本发明实施例提供了一种可穿戴设备，包括处理器110、环境光传感器130和屏幕120，如图3所示为本发明实施例提供的一种可穿戴设备的电路示意图，其中，环境光传感器130、屏幕120分别与处理器110连接，当然，处理器可以为一个处理器，也可以为多个处理器的集合。例如，处理器包括应用处理器和基带处理器，其中应用处理器和基带处理器可以分开设置，也可以集成为一体，本发明实施例对此并不限定。本实施例中，处理器可以为应用处理器。可以理解的是，环境光传感器130、屏幕120分别与处理器110连接中的连接，可以为直接连接，也可以为间接连接。本发明实施例对比并不限定。
本发明实施例提供的可穿戴设备在屏幕被点亮后，在人眼视觉暂留时间内，所述处理器调整所述屏幕的第一亮度至第一阈值以下；在所述人眼视觉 暂留时间内，所述环境光传感器检测所述可穿戴设备所处的第一环境光的亮度。
其中，人眼视觉暂留时间是指人眼在观看物体时，物体成像于视网膜上，并由视神经输入人脑，从而人眼感觉到物体的像；当物体移去时，视神经对物体的印象不会立即消失，而要延续1/24秒左右的时间，1/24秒(s)这段时间就是人眼视觉暂留时间，也就是说如果图像停留或消失40毫秒(ms)以内，视神经对物体的印象不会消失，从而不会影响人眼对图像的识别。因此，人眼视觉暂留时间可以为1/24s或40ms。
其中，屏幕亮度的第一阈值是指在该亮度阈值以下时，几乎无屏幕自发光或背光进入环境光传感器130。在此亮度阈值以下，环境光传感器130可以检测到相对真实的环境光亮度，此时，能够进入环境光传感器130的非环境光亮度几乎为零。第一阈值可以为50坎德拉/平方米(cd/m2)。所述处理器调整所述屏幕的第一亮度至第一阈值以下，可以为处理器调整所述屏幕的第一亮度为50cd/m2，也可以为处理器调整所述屏幕的第一亮度为40cd/m2。可以看出，第一阈值以下包括第一阈值本数。另，第一阈值可以根据实际情况设定。
屏幕的第一亮度泛指屏幕被点亮时的亮度。
其中，屏幕120还可以为LCD屏幕，由于OLED屏幕和LCD屏幕的发光原理不同，因此，处理器110调整屏幕120的第一亮度至第一阈值以下，可以包括对不同屏幕的不同处理方式，例如：
当屏幕120为OLED屏幕时，处理器110调整OLED屏幕的亮度至第一阈值以下。由于OLED是自发光显示，其亮度是处理器通过控制OLED内部的亮度调节寄存器来实现调整的。那么，当调整屏幕亮度在第一阈值以下时，可以由处理器，例如应用处理器，通过控制亮度调节寄存器直接调整屏幕亮度，使屏幕亮度小于或等于第一阈值。
所述屏幕120为LCD屏幕时，处理器110调整所述LCD屏幕的背光亮度至第一阈值以下。由于LCD屏幕是靠背光照明的，因此，当调整屏幕亮度 在第一阈值以下时，可以由处理器，例如应用处理器调整背光亮度，使屏幕亮度小于或等于第一阈值。
进一步的，本发明实施例中，处理器110调整屏幕120的第一亮度至第一阈值以下，不仅可以调整整个屏幕的亮度至第一阈值以下，还可以调整环境光传感器130所在的屏幕区域的亮度至第一阈值以下，即只要保证环境光传感器130检测时，进入环境光传感器感光元件的亮度不包括屏幕自发光或背光的影响即可。
本发明实施例中，当屏幕被点亮时的亮度可以为第一亮度，在人眼视觉暂留时间内，处理器调整屏幕的第一亮度至第一阈值以下，环境光传感器在这种情况下完成对可穿戴设备所处环境的环境光亮度的检测。
也就是说，在屏幕被点亮后，在处理器将屏幕的亮度调整到足够低，使得屏幕内部光线，如背光或屏幕的自发光线，可以忽略时，对环境光进行检测，这样能够保证进入环境光传感器的光线为真实的环境光。同时，为了不影响人眼对屏幕的观察，包括调整屏幕的亮度至第一阈值以下以及环境光传感器检测可穿戴设备所处的环境光亮度，这两个过程需要在人眼视觉暂留时间内完成。本发明实施例通过这种方式，在可穿戴设备屏幕被点亮，显示屏幕内容的过程中，能够在人眼无察觉的情况下，消除进入环境光传感器的非环境光，环境光传感器可以相对准确的检测到环境光的亮度。
进一步的，本发明实施例的一种可穿戴设备，在所述人眼视觉暂留时间内，所述环境光传感器检测所述可穿戴设备所处的第一环境光的亮度之后，处理器还用于根据第一环境光亮度调整屏幕的第一亮度。
具体的，当环境光传感器130完成对第一环境光亮度的检测后，处理器110可以根据环境光传感器130的检测结果调整屏幕的第一亮度，使屏幕的亮度调整为与环境光传感器130检测的环境光亮度对应的第二亮度，从而环境光传感器130完成一次检测，处理器完成一次屏幕亮度的调整。
需要说明的是，如果在一次检测中，环境光传感器130检测的环境光亮度未改变，则处理器110对屏幕亮度调整的幅度可以为零；如果环境光传感 器检测的环境光亮度相对于上一次环境光亮度变亮，则，处理器可以根据环境光亮度与屏幕亮度的对应关系，将屏幕亮度变亮；如果环境光传感器检测的环境光亮度相对于上一次环境光亮度变暗，则，处理器可以根据环境光亮度与屏幕亮度的对应关系，将屏幕亮度变暗。其中，环境光亮度与屏幕亮度的对应关系可以通过实验获得，也可以通过不断学习获得。该对应关系可以事先保存在终端中。
需要说明的是，可穿戴设备屏幕持续被点亮的过程中，可以以第一预定周期，不断对所述可穿戴设备所处环境的环境光亮度进行检测，其中，第一预定周期例如可以为：大于等于1s，且小于等于2s。也就是说，以第一预定周期，在人眼视觉暂留时间内，调整屏幕亮度至第一阈值以下并检测环境光亮度，根据检测的环境光亮度，调整屏幕亮度，从而，处理器110可以根据环境光的亮度来调整屏幕的亮度，保证人眼观察的舒适度。
可选的，在所述人眼视觉暂留时间内，所述环境光传感器130检测所述可穿戴设备所处的第一环境光的亮度之后，处理器110可以先恢复屏幕120的第一亮度，然后根据第一环境光的亮度，调整屏幕的第一亮度。当然，处理器110也可以如前所述，根据第一环境光的亮度，直接调整屏幕的第一亮度。
可以理解，如果从处理器110将屏幕120的第一亮度调整至第一阈值以下到环境光传感器130完成环境光亮度检测的时长小于人眼视觉暂留时间，则处理器可以在环境光传感器完成环境光亮度的检测后立即恢复屏幕的第一亮度。处理器还可以在到达人眼视觉暂留时间的时长时恢复屏幕的第一亮度。当恢复了屏幕的第一亮度后，处理器再根据环境光传感器的检测结果调整屏幕的第一亮度。
根据环境光传感器的检测结果，调整屏幕亮度，使得屏幕亮度能够更好的反应环境光的变化，提高用户的舒适度。
下面通过图4，描述环境光传感器检测可穿戴设备所处环境光的过程。图4为本发明实施例的可穿戴设备在对环境光检测时的执行时间示意图。
在t1时刻，可穿戴设备的屏幕被点亮，该亮度可以为第一亮度即屏幕被点亮时的亮度；
处理器例如应用处理器，在t2时刻开始执行对屏幕亮度的调整；
在t2到t3时间段内，处理器首先将屏幕亮度调整至40cd/cm2即第一阈值以下，屏幕在该亮度时，屏幕亮度可以忽略，对环境光传感器的影响也可以忽略，在该亮度下，环境光传感器开始对可穿戴设备所处的环境光进行测量，环境光传感器接收到处理器发送的执行检测的命令后，对可穿戴设备所处的环境光进行测量并获得检测结果，环境光传感器对可穿戴设备所处的环境光亮度测量完毕后，将测量的第一环境光亮度反馈给处理器，t2-t3时间段的时间长度小于或等于人眼视觉暂留时间，其优选可以为10ms-30ms，也就是说，处理器将屏幕亮度调整至第一阈值以下、环境光传感器对可穿戴设备所处的环境光的检测均是在t2-t3时间段内完成的；
处理器接收到环境光传感器反馈的检测完毕的消息后，可以在t3时刻先恢复屏幕的第一亮度；
在t3到t4时间段内，处理器可以根据检测出的第一环境光亮度，计算或通过查找预设对应表等方式获得与第一环境光亮度对应的屏幕亮度，并在t4时刻将屏幕调整至与第一环境光亮度对应的屏幕亮度；
可选的，处理器根据环境光传感器检测的第一环境光亮度计算或通过查找预设对应表等方式获得与第一环境光亮度对应的屏幕亮度的过程，也可以在t2到t3时间段内完成，那么，处理器会在t3时刻，根据已获得的与第一环境光亮度对应的屏幕亮度，调整屏幕亮度。
本发明实施例中的可穿戴设备，可以以t1到t3，或从t1到t4时间段的时间长度为第一预定周期，当处理器在t3时刻或t4时刻完成对屏幕亮度的调整。可以理解的是，在第一预定的周期内，可穿戴设备可以重复执行上述对可穿戴设备所处的环境光亮度的检测，进而保证可穿戴设备所处环境产生变化时，环境光传感器能够及时检测环境变化，处理器能够根据环境光传感器的检测结果及时调整屏幕亮度。
需要说明的是，由于环境光传感器是对从屏幕透射过来的环境光的检测，如果有用户手指在屏幕上的操作，会影响透射到环境光传感器的环境光，导致环境光传感器检测不准确。
为了避免这种操作带来的检测错误，本发明实施例中，根据第一环境光的亮度，调整屏幕的第一亮度具体可以为：
如果第一环境光的亮度小于所述环境光传感器130的上一次检测的环境光的亮度，所述处理器110还用于检测是否有触摸屏幕的操作；如果没有触摸操作，所述处理器根据所述第一环境光的亮度调整所述屏幕的所述第一亮度。
即，当第一环境光的亮度小于上一次检测的环境光时，可能是由于用户的触摸屏幕的操作导致的，那么此时处理器110还用于判断是否有触摸屏幕的操作，如果没有，则表示检测准确，处理器可以根据检测的第一环境光的亮度对屏幕的亮度进行调整。如果有，则表示检测结果可能受到了用户触摸屏幕操作的影响，则放弃本次检测结果，对屏幕亮度的调整幅度可以为零。其中，判断是否有触摸屏幕的操作可以采用现有技术来实现，在此不再赘述。
由于进一步判断了是否有用户触摸屏幕的操作，降低了检测误差。
可选的，本发明实施例的一种可穿戴设备，在所述人眼视觉暂留时间内，所述环境光传感器130检测所述可穿戴设备所处的第一环境光的亮度之后，处理器110可以恢复屏幕120的第一亮度；所述处理器110控制所述屏幕120的所述第一亮度的时长在第一预设范围；在所述人眼视觉暂留时间内，所述处理器调整所述第一亮度至所述第一阈值以下；在所述人眼视觉暂留时间内，所述环境光传感器130检测所述可穿戴设备所处的第二环境光的亮度；所述处理器根据所述环境光传感器检测的所述第一环境光的亮度和所述第二环境光的亮度，调整所述屏幕的所述第一亮度。
具体的，当环境光传感器130完成第一环境光亮度检测后，由处理器110记录该第一环境光的检测结果，并恢复屏幕120的第一亮度；屏幕在恢复第一亮度后，屏幕以第一亮度显示一段时间，保证人眼可以观看到屏幕内容后， 再执行第一次检测环境光亮度过程，即在人眼视觉暂留时间内，调整屏幕的第一亮度低于第一阈值，环境光传感器对第二环境光亮度进行检测，获得第二环境光亮度，此时，处理器根据第一环境光亮度和第二环境光亮度确定可穿戴设备所处的环境光亮度，处理器基于确定的环境光亮度对屏幕的第一亮度进行调整。
其中，处理器根据第一环境光亮度和第二环境光亮度确定可穿戴设备所处的环境光亮度，例如可以为：处理器将第一环境光亮度和第二环境光亮度进行求和再取平均的结果作为确定的可穿戴设备所处的环境光亮度。然后，处理器可以根据确定的环境光亮度对屏幕的第一亮度进行调整。
为了保证后续检测的第二环境光亮度与第一环境光亮度是在同样环境光条件下获得的，需要控制显示屏幕内容的时长在第一预设范围，第一预设范围是指屏幕点亮的时间长度能够保证用户可以获取到屏幕内容的一个时间长度范围，如果恢复屏幕的第一亮度的时长小于第一预设范围，就再次调整屏幕亮度至第一阈值以下，可能会由于人眼视觉暂留时间导致用户仍然停留在屏幕亮度在第一阈值以下的近似于黑屏的视觉状态中，而影响用户对屏幕内容的获取，因此，本发明实施例中，第一预设范围例如为：2倍人眼视觉暂留时间≤第一预设范围≤1s。
简单说，就是在人眼视觉暂留时间内，调整屏幕第一亮度至第一阈值以下，环境光传感器130检测第一环境光亮度；处理器110恢复屏幕120的第一亮度，并保持人眼能够获取屏幕内容的时长，然后，在人眼视觉暂留时间内，处理器再调整屏幕第一亮度至第一阈值以下后，环境光传感器检测第二环境光亮度。这样，处理器根据环境光传感器检测的第一环境光的亮度和第二环境光的亮度，调整屏幕的第一亮度。
由于采用了两次环境光亮度的检测结果确定可穿戴设备所处的环境光亮度，使得检测结果更加准确。
为进一步提高检测结果的准确性，本发明实施例进一步的采用如下获得可穿戴设备所处的环境光亮度的技术方案：
当环境光传感器完成第一环境光亮度检测后，处理器记录该第一环境光亮度的检测结果，处理器恢复屏幕的第一亮度并保持第一预设范围，例如1/6s；再执行一次检测环境光亮度的过程，即在人眼视觉暂留时间内，调整屏幕的第一亮度低于第一阈值，环境光传感器对第二环境光亮度进行检测，以获得第二环境光亮度；当第一环境光亮度与第二环境光亮度的差值大于或等于第二阈值时，例如50cd/m2，则认为第一环境光亮度或第二环境光亮度中有至少一个不准确，丢弃前一次即第一环境光亮度的检测结果，按照第一环境光亮度的检测方法，进行第三环境光亮度的检测，即：在人眼视觉暂留时间内，调整屏幕的第一亮度低于第一阈值，环境光传感器对环境光亮度检测，获得第三环境光亮度。如果第二环境光亮度与第三环境光亮度的差值仍然大于或等于第二阈值，则继续重复检测环境光的步骤，直至获得连续两次环境光亮度的差值小于第二阈值时，根据连续两侧检测的环境光亮度确定可穿戴设备所处的环境光亮度，例如可以对连续两次环境光亮度求和再取平均的方式，确定环境光亮度，处理器根据最终确定的环境光亮度来调整屏幕的第一亮度。
由于根据连续两次较小误差的环境光亮度检测结果来确定环境光的亮度，从而使得环境光亮度检测的结果更准确。
第二实施例：
可以参考图2和3，本发明第二实施例还提供一种可穿戴设备。其中，可穿戴设备包括处理器110、环境光传感器130和屏幕120。环境光传感器130、屏幕120分别与处理器110相连接。环境光传感器130的感光元件朝向屏幕并位于所述屏幕下表面。当屏幕120被点亮后，在人眼视觉暂留时间内，处理器110控制图像数据，所述控制后的图像数据的灰阶值小于或等于第一阈值；在人眼的视觉暂留时间内，环境光传感器130检测可穿戴设备所处的第一环境光的亮度。
具体的，该可穿戴式设备可以包括FPC软板140，环境光传感器130可 以置于FPC软板140上，环境光传感器130可以通过FPC软板140与处理器110相连接。可选的，屏幕120也可以通过FPC软板与处理器110相连接，其中，屏幕120与处理器110连接的FPC软板可以与环境光传感器130连接处理器110的FPC软板140可以相同，也可以不相同，本实施例对此并不限定。
可以理解的是，环境光传感器、屏幕分别与处理器连接中的连接，可以为直接连接，也可以为间接连接；当然，处理器可以为一个处理器，也可以为多个处理器的集合。例如，处理器包括应用处理器和基带处理器，其中应用处理器和基带处理器可以分开设置，也可以集成为一体，本发明实施例对此并不限定。本实施例中，处理器可以为应用处理器。
进一步的，请参阅图2，终端还可以包括黑胶层1203，黑胶层1203位于屏幕的下表面1202，环境光传感器130设置于黑胶层1203的镂空区域1204，屏幕可以为有机发光二极管OLED屏幕。
本实施例中的黑胶层1203可以根据其具有的不同功能而具有不同的名称，例如，具有遮光的作用的遮光黑胶层、具有缓冲作用的缓冲黑胶层、具有缓冲和遮光的作用的缓冲遮光黑胶层等，黑胶层位于屏幕的下表面，可以是贴合，也可以直接放置，即本实施例中的黑胶层并不一定具有粘性，在此不做限定。
进一步的，处理器控制图像数据，所述控制后的图像数据的灰阶值小于或等于第一阈值的具体方式例如，
可以为：
处理器调整所述屏幕显示的图像数据，所述调整后的图像数据的灰阶值小于或等于第一阈值。
具体来说，处理器可以通过调整屏幕正在显示的图像数据，使当前的图像数据的灰阶值降低，并小于或等于第一阈值。
还可以为：
处理器插入图像数据，所述插入的图像数据的灰阶值小于或等于第一阈 值。
具体来说，处理器在当前屏幕正在显示的图像数据中插入新的图像数据，新的图像数据的灰阶值小于或等于第一阈值，这样新的图像数据覆盖了正在显示的图像数据。
需要说明的是，本实施例中的第一阈值与第一实施例中的第一阈值不同。
其中，图像数据的灰阶值在第一阈值以下，是指图像数据为全黑或近似于黑色，例如，第一阈值＝RGB(50,50,50)，就是说，当图像数据的R、G、B的灰阶值均在小于或等于50时，可以认为图像数据近似为黑色，此时，能进入环境光传感器的屏幕内部光线几乎为零，对于人眼来说，屏幕也几乎为黑色。
下面以插入图像数据的灰阶值小于或等于第一阈值为例简单进行说明。图5为本发明实施例在屏幕显示的内容中插入近似于黑色图像数据帧的示意图。如图5所示，在显示一帧图像数据之后，插入一帧近似于黑色图像，该近似于黑色图像的一帧图像数据可以覆盖于正在显示的图像数据之上，对于人眼而言，还停留在前一帧图像数据，并不会影响人眼查看屏幕显示的内容，在所述人眼视觉暂留时间内，环境光传感器130完成对可穿戴设备所处环境光亮度的检测。
其中，图像数据可以为图像帧，考虑到在所述人眼视觉暂留时间内，插入的近似于黑色图像帧的时间内环境光传感器130是否能够完成检测，本发明实施例中，可穿戴设备可以根据图像帧数来调整插入的近似于黑色图像帧的数目，只要插入的近似于黑色图像帧的总时长小于人眼视觉暂留时间，环境光传感器能够在这段时间内完成环境光亮度的检测即可。
进一步的，所述处理器，还用于根据第一环境光的亮度，调整所述图像数据的灰阶值。
其中，所述处理器，根据第一环境光的亮度，调整所述图像数据的灰阶值，具体可以为：
如果所述第一环境光的亮度小于所述环境光传感器的上一次检测的环境 光的亮度，所述处理器还用于检测是否有触摸屏幕的操作；
如果没有触摸操作，所述处理器根据所述第一环境光的亮度调整所述图像数据的所述灰阶值。
其中，所述处理器控制图像数据，具体为：
所述处理器控制屏幕区域的全部图像数据，或所述环境光传感器所在的屏幕区域的图像数据。
本发明实施例的另一种可穿戴设备在屏幕被点亮后，在人眼视觉暂留时间内，在处理器控制图像数据，控制后的图像数据的灰阶值至足够黑时，使得屏幕内部光线可以忽略，此时环境光传感器完成对环境光亮度的检测，这样保证了进入环境光传感器的光线为真实的环境光。需要说明的是，为了不影响人眼对屏幕内容的观察，处理器控制图像数据，控制后的图像数据的灰阶值小于或等于第一阈值以及环境光传感器检测可穿戴设备所处的环境光亮度的两个过程，需要在一个人眼视觉暂留时间内完成。本发明实施例的另一种可穿戴设备通过这种方式，在可穿戴设备屏幕被点亮显示屏幕内容过程中，在人眼无察觉的情况下，消除了进入环境光传感器的非环境光，环境光传感器可以检测到相对真实的环境光亮度。
本发明实施例进一步给出实现上述终端实施例中对应的检测环境光亮度的方法。
对应于本发明第一实施例的一种可穿戴设备，图6为本发明实施例的一种检测环境光亮度的方法的流程示意图。如图6所示，该方法包括：
步骤601、当屏幕被点亮后，在人眼视觉暂留时间内，所述终端调整所述屏幕的第一亮度至第一阈值以下。
具体的，所述屏幕可以为有机发光二极管OLED屏幕，所述终端调整所述OLED屏幕的亮度至第一阈值以下；或
所述屏幕为液晶显示LCD屏幕，所述终端调整所述LCD屏幕的背光亮度至第一阈值以下。
进一步的，所述终端不仅可以调整整个屏幕的第一亮度值至第一阈值以 下，还可以调整所述环境光传感器所在的屏幕区域的亮度至第一阈值以下。
其中，所述第一阈值可以为50cd/cm2。
步骤602、在所述人眼视觉暂留时间内，所述终端的环境光传感器检测所述终端所处的第一环境光的亮度。
本发明实施例中，当屏幕被点亮时，在人眼视觉暂留时间内，调整屏幕的第一亮度至第一阈值以下，环境光传感器在这种情况下完成对可穿戴设备所处环境的环境光亮度的检测。通过这种方式，在可穿戴设备屏幕被点亮，显示屏幕内容的过程中，能够在人眼无察觉的情况下，消除进入环境光传感器的非环境光，环境光传感器能够检测到相对真实的环境光的亮度。
进一步的，在步骤602之后还可以包括：
步骤603、所述终端恢复所述屏幕的所述第一亮度；所述终端根据所述第一环境光的亮度，调整所述屏幕的所述第一亮度。
具体的，当终端根据所述第一环境光的亮度，调整所述屏幕的所述第一亮度时，具体为：如果所述第一环境光的亮度小于上一次检测的环境光的亮度，所述终端检测是否有触摸屏幕的操作；
如果没有触摸操作，所述终端根据所述第一环境光的亮度调整所述屏幕的所述第一亮度。
与步骤603可替换的，在步骤602之后还可以包括：
步骤604、所述终端根据所述第一环境光的亮度，调整所述屏幕的所述第一亮度。
具体的，当终端根据所述第一环境光的亮度，调整所述屏幕的所述第一亮度时，具体为：如果所述第一环境光的亮度小于上一次检测的环境光的亮度，所述终端检测是否有触摸屏幕的操作；
如果没有触摸操作，所述终端根据所述第一环境光的亮度调整所述屏幕的所述第一亮度。
由于进一步判断了是否有用户触摸屏幕的操作，降低了检测误差。
与步骤603或604可替换的，在步骤602之后还可以包括步骤605-609， 其中，
步骤605、所述终端恢复所述屏幕的所述第一亮度；
步骤606、所述终端控制所述屏幕的所述第一亮度的时长在第一预设范围；
其中，第一预设范围是指屏幕点亮的时间长度能够保证用户可以获取到屏幕内容的一个时间长度范围，第一预设范围例如为：2倍人眼视觉暂留时间≤第一预设范围≤1s。
步骤607、在所述人眼视觉暂留时间内，所述终端调整所述第一亮度至所述第一阈值以下；
步骤608、在所述人眼视觉暂留时间内，所述环境光传感器检测所述终端所处的第二环境光的亮度；
步骤609、所述终端根据所述环境光传感器检测的所述第一环境光的亮度和所述第二环境光的亮度，调整所述屏幕的所述第一亮度。
根据第一环境光的亮度和第二环境光的亮度，调整屏幕的第一亮度的方式与第一实施例中所示终端的调整方法相同，在此不再赘述。
由于根据连续两次较小误差的环境光亮度检测结果来确定环境光的亮度，从而使得环境光亮度检测的结果更准确。
对应于本发明第二实施例的可穿戴设备，图7为本发明实施例的另一种检测环境光亮度的方法的流程图示意。如图7所示，该方法包括：
步骤701、当屏幕被点亮后，在人眼视觉暂留时间内，所述终端控制图像数据，所述控制后的图像数据的灰阶值小于或等于第一阈值。

步骤702、在所述人眼的视觉暂留时间内，所述终端的环境光传感器检测所述终端所处的第一环境光的亮度。
进一步的，在步骤702之后还可以包括步骤703：
步骤703、所述终端根据所述第一环境光的亮度，调整所述图像数据的所述灰阶值。
在终端根据所述第一环境光的亮度，调整所述图像数据的所述灰阶值时，具体为：如果第一环境光的亮度小于所述环境光传感器的上一次检测的环境光的亮度，所述终端检测是否有触摸屏幕的操作；如果没有触摸操作，所述终端根据所述第一环境光的亮度调整所述图像数据的所述灰阶值。
本发明实施例当屏幕被点亮时，在人眼视觉暂留时间内，控制图像数据，控制后的图像数据的灰阶值小于或等于第一阈值，环境光传感器在这种情况下完成对可穿戴设备所处环境的环境光亮度的检测。通过这种方式，在可穿戴设备屏幕被点亮，显示屏幕内容的过程中，能够在人眼无察觉的情况下，消除进入环境光传感器的非环境光，环境光传感器能够检测到相对真实的环境光的亮度。
