图2是本发明调节装置的结构框图；

图4是人眼的视野范围示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步详细说明。
如图1和图4所示，本发明公开了一种屏幕亮度调节方法，包括如下步骤：
获取人眼视野范围内可见光最大亮度区域所在位置；
根据可见光最大亮度区域所在位置的亮度和/或人眼瞳孔大小变化对屏幕亮度进行调节。
所述获取人眼视野范围内可见光最大亮度区域所在位置具体为，对获取人眼视野范围内可见光最大亮度区域所在位置进行判断，常规情况下，可见光最大亮度区域一般存在两种情况，一种为位于屏幕区域内(如图4中的B点)，即与屏幕亮度有关，另一种为位于屏幕区域外(如图4中的A点和C点)，即与环境光亮度有关，根据这一原理，当人眼视野范围内可见光最大亮度区域所在位置位于屏幕区域外，则获取当前屏幕区域外环境光亮度以及人眼瞳孔大小，根据屏幕区域外环境光亮度以及人眼瞳孔大小变化，对屏幕亮度进行调节。图6中L1和L2为人眼视野范围区域。
对屏幕亮度进行调节具体为提高屏幕亮度或降低屏幕亮度。
所述根据屏幕区域外环境光亮度以及人眼瞳孔大小变化，对屏幕亮度进行调节具体为判断环境光最大亮度是否大于屏幕亮度以及判断人眼瞳孔大小，当 环境光最大亮度大于屏幕亮度且人眼瞳孔缩小时，则提高屏幕亮度；当环境光最大亮度小于屏幕亮度且人眼瞳孔放大时，则降低屏幕亮度。
根据屏幕区域外环境光亮度以及人眼瞳孔大小变化，对屏幕亮度进行调节可采用以下公式计算出相应的屏幕亮度；
L＝kL0×exp(d/d0)，
其中k为比例系数，L0为标准环境光亮度下的面板亮度，d0为标准环境光下的人眼瞳孔大小，d为某一环境光下的人眼瞳孔大小；
通过上述公式的计算，可以计算出符合人眼亮度特性的显示曲线，但本发明不限于此，还可通过实验生成相应的关系表，根据人眼瞳孔大小以及环境光亮度建立对应关系，进行相应的调节。
当获取人眼视野范围内可见光最大亮度区域所在位置为屏幕区域内时，则根据环境光亮度变化对屏幕亮度进行调节。
当可见光最大亮度区域所在位置为屏幕区域内时，假设在第一环境中，B点为最大亮度，当人移动或所处环境变化到第二环境中，最大亮度还是B点时，设第一环境的环境光亮度为M，B点的亮度为L，第二环境的环境光亮度为N，则第二环境中B点的亮度为NL/M，由于第二环境中的环境光亮度可能大于第一环境中环境光亮度，也可能小于，所以B点的亮度可能升高，可能降低，因此屏幕亮度调节仅需根据当前屏幕亮度和当前环境光亮度的比值等比例提升或降低，这里的调节方法为现有技术中的调节方法，即将屏幕亮度调整至与环境光亮度相同即可。
如图2所示，本发明还公开了一种屏幕亮度的调节装置，所述调节装置包括：
光线感应器，用于获取人眼视野范围内可见光最大亮度；
亮度分析装置，用于分析可见光最大亮度的区域所在位置；并根据可见光最大亮度的区域所在位置的亮度和/或人眼瞳孔大小变化生成相应的控制信号；
亮度调节和控制装置，用于接收控制信号，并根据相应的控制信号对屏幕亮度进行调节。
所述调节装置还包括眼球追踪装置，用于获取人眼瞳孔大小变化。
所述控制信号为控制背光控制电路的电压的信号，对屏幕亮度进行调节具体为提高屏幕亮度或降低屏幕亮度。
所述亮度分析装置还包括对获取人眼视野范围内可见光最大亮度区域所在位置进行判断，当人眼视野范围内可见光最大亮度区域所在位置位于屏幕区域外，则获取当前屏幕区域外环境光最大亮度以及获取人眼瞳孔大小，根据屏幕区域外环境光最大亮度以及人眼瞳孔大小变化，生成相应的控制信号。
所述亮度分析装置还包括当获取人眼视野范围内可见光最大亮度的区域所在位置为屏幕区域内时，则根据环境光亮度变化生成相应的控制信号。
当可见光最大亮度区域所在位置为屏幕区域内时，假设在第一环境中，B点为最大亮度，当人移动或所处环境变化到第二环境中，最大亮度还是B点时，设第一环境的环境光亮度为M，B点的亮度为L，第二环境的环境光亮度为N，则第二环境中B点的亮度为NL/M，由于第二环境中的环境光亮度可能大于第一环境中环境光亮度，也可能小于，所以B点的亮度可能升高，可能降低，因此屏幕亮度调节仅需根据当前屏幕亮度和当前环境光亮度的比值等比例提升或降低，这里的调节方法为现有技术中的调节方法，即将屏幕亮度调整至与环境光亮度相同即可。
根据屏幕区域外环境光最大亮度以及人眼瞳孔大小变化，生成相应的控制信号具体为判断环境光最大亮度是否大于屏幕亮度以及判断人眼瞳孔大小，当环境光最大亮度大于屏幕亮度且人眼瞳孔缩小时，则提高屏幕亮度；当环境光最大亮度小于屏幕亮度且人眼瞳孔放大时，则降低屏幕亮度。
根据屏幕区域外环境光亮度以及人眼瞳孔大小变化，对屏幕亮度进行调节可采用以下公式计算出相应的屏幕亮度；
L＝kL0×exp(d/d0)，
其中k为比例系数，L0为标准环境光亮度下的面板亮度，d0为标准环境光下的人眼瞳孔大小，d为某一环境光下的人眼瞳孔大小；
通过上述公式的计算，可以计算出符合人眼亮度特性的显示曲线，但本发 明不限于此，还可通过实验生成相应的关系表，根据人眼瞳孔大小以及环境光亮度建立对应关系，进行相应的调节。
本发明的调节装置中，亮度分析装置可包括第一亮度分析装置、第二亮度分析装置、第三亮度分析装置，其中：
第一亮度分析装置，用于分析可见光最大亮度的区域所在位置；
第二亮度分析装置，用于当人眼视野范围内可见光最大亮度区域所在位置位于屏幕区域外时，获取当前屏幕区域外环境光最大亮度以及根据人眼瞳孔大小，生成相应的控制信号。具体地，当人眼视野范围内可见光最大亮度区域所在位置位于屏幕区域外时，第一亮度分析装置向第二亮度分析装置发送获取指令。
第三亮度分析装置，用于当获取人眼视野范围内可见光最大亮度的区域所在位置为屏幕区域内时，根据环境光亮度变化生成相应的控制信号。具体地，当人眼视野范围内可见光最大亮度区域所在位置位于屏幕区域内时，第一亮度分析装置向第三亮度分析装置发送获取指令。
本发明中光线感应器以及眼球追踪装置均设置与人眼相对的位置处。
下面结合本发明的屏幕亮度调节方法及调节装置对本发明的具体流程进行相应的描述(如图3所示)；
步骤S1、光线感应器获取人眼视野范围内可见光最大亮度；
步骤S2、第一亮度分析装置根据光线感应器获取人眼视野范围内可见光最大亮度判断可见光最大亮度所在位置是否位于屏幕区域外；
步骤S3、当人眼视野范围内可见光最大亮度区域所在位置位于屏幕区域外时(是)，第二亮度分析装置获取当前屏幕区域外环境光最大亮度以及根据人眼瞳孔大小，生成相应的控制信号并发送至亮度调节和控制装置；
步骤S4、当获取人眼视野范围内可见光最大亮度的区域所在位置为屏幕区域内时(否)，第三亮度分析装置根据环境光亮度变化生成相应的控制信号并发送至亮度调节和控制装置；
步骤S5、亮度调节和控制装置根据相应的控制信号对屏幕亮度进行调节。
在本发明中，亮度调节和控制装置调节屏幕亮度具体为调节屏幕的背光， 也就是说通过调整背光控制电路的电压，实施调控。
本发明通过在显示装置(如手机或显示器)中加入人眼亮度感光装置，通过环境光亮度感应和人眼瞳孔大小感应两方面结合来调节显示装置亮度，提高人眼观看舒适性，达到健康护眼的效果。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
