本申请涉及显示技术领域，尤其涉及一种背光调整的方法及装置。
背光调节技术已经广泛应用于显示领域，对显示器的背光调节通常有手动调节和自动调节两种调节技术，其中，自动背光调节技术，当环境光照强度发生变化时，根据环境光照强度与背光值之间的映射关系，确定出当前环境光照强度对应的背光值，并对显示器的背光值进行调整，由于用户个体感光的差异，在自动调节之后结合手动调节，以使得显示器的背光值适配用户对光强亮暗的需求。目前，在自动背光模式下，通过用户手动拖动亮度条的位置的变化来确定对应的背光调节因子，再基于所述背光调节因子对显示器的背光值进行调整。虽然相关技术背光调节技术能够基本满足用户对光照强度亮暗的需求，但是通过这种方法确定的背光调节因子的大小，而不能反映用户调整后的背光值小于自动背光值，还是调整后的背光值大于自动背光值，即不能反映用户调大或调小背光值的规律，不能真正适配用户对背光值抑制或补偿的需求，导致用户的体验效果不佳。

实施例一
以下结合说明书附图对本申请实施例所提供的一种背光调整的方法做进一步详细的说明，该方法具体实现方式可以包括以下步骤(方法流程如图1所示)：
步骤101，电子设备处于自动调节背光的模式下，采集自动调节的第一背光值和基于用户调整规律得到的第二背光值；
电子设备包括触控显示屏或亮度调节按键。电子设备处于自动调节背光的模式下，环境光照强度与自动调节的背光值之间存在着预设的映射关系，基于环境光照强度确定出对应的自动调节的第一背光值，电子设备将背光值调整到第一背光值，由于不同用户的感光能力不同，在自动背光调节的基础上用户可以通过在触控显屏上拖动亮度条来调整背光值得到第二背光值，也可以通过亮度调节按键来调整背光值得到第二背光值，电子设备采集自动调节的第一背光值和基于用户调整规律得到的第二背光值，其中，所述用户调整规律包括用户习惯将自动背光值调大或将自动背光值调小的规律。
例如，在环境光照强度为500勒克斯(LX)时，基于环境光照强度与自动调节的背光值之间的映射关系，确定出对应的自动调节的背光值为20，而用户在使用电子设备的过程中，屏幕的背光值为20对于用户来说太亮了，用户需要通过手动拖动触控显示屏上的亮度条或通过亮度调节按键将背光值调整到15，以适应用户的亮度需求，电子设备采集环境光照强度为500勒克斯(LX)时，电子设备自动调节的第一背光值为20和基于用户调整规律得到的第二背光值为15。
步骤102，电子设备基于所述第一背光值和所述第二背光值，确定背光调节因子；
电子设备基于操作系统中预设的算法，根据第一背光值和第二背光值计算背光调节因子。
背光调整因子体现了用户调整后的背光值与自动背光值之间的关系，具体的，电子设备通过下式计算所述背光调节因子：
Adj＝(user-AutoBri)/(MaxBri-MinBri)
其中，Adj为所述背光调节因子，user为所述第二背光值，AutoBri为所述第一背光值，MaxBri为最大背光值，MinBri最小背光值。
电子设备预先将背光值的范围设置为[MinBri，MaxBri]，电子设备基于环境光照强度确定出对应的自动调节的背光值，用户会在自动调节的背光值的基础上拖动电子设备的亮度条来调整背光值，用户调整后的背光值可能大于自动调节的背光值，也可能小于自动调节的背光值，当用户调整后的背光值大于自动调节的背光值时，电子设备会对显示屏幕的背光值进行补偿，当用户调整后的背光值小于自动调节的背光值时，电子设备会对显示屏幕的背光值进行抑制，因此，为了确定电子设备对显示屏幕的背光值进行补偿或抑制区域，以自动调节的背光值为基准参数，确定背光调整因子的取值范围。
参见图2所示，电子设备基于所述AutoBri将背光值调整的范围分为第一区域和第二区域，其中，所述第一区域的范围为[MinBri，AutoBri]，所述第二区域的范围为[AutoBri，MaxBri]，然后，检测所述第二背光值所在的区域，若检测到所述第二背光值所在的区域为所述第一区域，则确定所述背光调节因子为负值，若检测到所述第二背光值所在的区域为所述第二区域，则确定所述背光调节因子为正值，当AutoBri最大背光值，user为最小背光值时，背光调整因子为-1，当AutoBri最小背光值，user为最大背光值时，背光调整因子为1，进而确定所述背光调节因子的取值范围为[-1,1]。
步骤103，当电子设备检测到环境光照强度由第一光照强度变化到第二光照强度时，确定所述第二光照强度对应的第三背光值，其中，所述第三背光值为所述第二光照强度对应的自动调节的背光值；
电子设备中包括光电传感器、光敏器件(如光敏电阻、光电二极管)和光照强度感应开关等。当电子设备通过光电传感器、光敏器件或光照强度感应开关检测到环境光照强度由第一光照强度变化到第二光照强度时，基于环境光照强度与自动调节的背光值之间的预设映射关系，确定第二光照强度对应的自动调节的第三背光值。例如，基于预设的映射关系确定出环境光照强度为300LX时，对应的自动调节的背光值为30，当电子设备检测到环境光照强度从500LX变化到300LX时，即可确定第三背光值为30。
步骤104，电子设备基于所述背光调节因子对所述第三背光值进行调整得到所述第二光照强度对应的满足所述用户调整规律的第四背光值。
当电子设备基于操作系统预设的算法计算得到背光调节因子之后，电子设备将所述背 光调节因子作为输入参数，利用以下公式对所述第三背光值进行调整得到所述第二光照强度对应的满足所述用户调整规律的第四背光值：
gamma＝3.0^(-Adj)
Value＝AutoBri/255
AdjAutoBri＝Math.round((Value^gamma)*255)
其中，gamma为背光值的抑制补偿的中间系数，Value为所述第三背光值的归一化值，AdjAutoBri为所述第四背光值，用来表示满足用户调整规律的背光值与自动调节的背光值以及背光调整因子之间的关系；Math.round()表示一个计算函数，该函数用于表示对计算结果进行四舍五入。
例如，电子设备显示器最小的背光值MinBri设置为0，最大的背光值MaxBri为255。当电子设备检测到光照强度的第二光照强度为300LX时，首先，电子设备采集得到自动调节的第一背光值为30，采集基于用户调整规律得到的第二背光值为25，然后，基于电子设备基于预设的算法计算出背光调节因子Adj＝-1/51，再基于所述背光调节因子的值，确定出背光的抑制补偿的中间系数gamma＝3.0^(1/51)和自动调节的背光值对应的归一化值Value＝2/17，最后，基于gamma和Value值确定出满足用户调整规律的第四背光值AdjAutoBri＝29。
