具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种背光调节方法，参照图1，在本发明背光调节方法第一实施例中，该背光调节方法包括以下步骤：
步骤S10，根据终端当前所处的地理位置信息获取对应的背光增益曲线，所述背光增益曲线包括各时间点与背光增益值的映射关系；
本发明提供的背光调节方法主要应用于智能终端的背光调节系统，用于对背光的强度进行调节。该终端可以包括电视机、手机和平板等等。具体地，上述地理位置信息可以为终端当前所处的经纬度信息。一定范围的经纬度可以对应一背光增益曲线。应当说明的是，上述背光增益曲线可以根据上述地理位置信息计算得到，也可储存在服务器端，由终端将当前所处的地理位置信息发送到服务器端，以获取当前地理位置信息对应的背光增益曲线。上述背光增益值反映背光强度，上述背光增益曲线表示各时间点对应的背光强度变化曲线。
步骤S20，根据当前的时间点查询所述背光增益曲线上对应的背光增益值；
步骤S30，根据所述背光增益值调节所述终端的背光强度。
本实施例中，在每一时间点上均对应一背光增益值，可以理解的是，不同时间点上的背光增益值可以相同，也可以不同；例如在白天时的背光增益值大于在晚上时的背光增益值。在获取到上述背光增益曲线后，可根据当前的时间点在背光增益曲线上查找该时间点对应的背光增益值，然后根据该背光增益值对终端的背光强度进行调节。具体地，该背光强度与环境光线强度有光，当环境光线强度越强时，需要控制背光强度也要越强（即在白天的时候背光增益值越大）；当环境光线强度越弱时，需要控制背光强度也要越弱（即在晚上的时候背光增益值越小）。
可以理解的是，可以在终端设置特定的背光调节模式，以控制终端是否根据时间点调节终端的背光强度。具体地，在未开启该特定的背光调节模式时，可以按照现有的背光调节方式进行背光控制，只有当用户开启特定的背光调节模式时，才根据当前的时间点查询所述背光增益曲线上对应的背光增益值，然后根据所述背光增益值调节所述终端的背光强度。
本发明实施例通过根据终端当前所处的地理位置信息获取对应的背光增益曲线；根据当前的时间点查询所述背光增益曲线上对应的背光增益值；然后根据所述背光增益值调节所述终端的背光强度，从而实现了根据时间点对终端的背光强度进行自动调节，以使背光强度随时间的变化自动变化调节。因此本发明实施例提供的背光调节方法降低了背光调节的操作难度和电量的损耗。
进一步地，参照图2基于本发明背光调节方法第一实施例，在本发明背光调节方法第二实施例中，上述步骤S30包括：
步骤S31，根据终端预置用于控制背光强度的历史脉宽调制信号的历史占空比和所述背光增益值计算获得调整后的新占空比；
步骤S32，根据所述新占空比输出新脉宽调制信号至背光系统，以调整所述终端的背光强度。
在本实施例中，背光控制系统中设有用于控制背光强度的脉宽调制信号，该脉宽调制信号用于输出到背光控制系统的开关管中，以控制在周期时间内背光开启的时间长度。当脉宽调制信号的占空比越大，则表示周期时间内背光开启的时间越长，背光强度越强。在进行背光调整时，可以获取历史脉宽调制信号的历史占空比，然后根据该历史站空比和背光增益值重新计算调整后的新占空比。然后根据该新的占空比输出新脉宽调制信号至背光系统，从而调整终端的背光强度。可以理解的是，上述预置的历史脉宽调制信号包括第一脉宽调制信号和第二脉宽调制信号，该第一脉宽调制信号的占空比为第一占空比，该第二脉宽调制信号为第二占空比；上述历史占空比包括所述第一占空比和所述第二占空比。上述第一脉宽调制信号为用户在开启上述特定的背光调节模式前，背光系统中用于控制背光强度所输出的脉宽调制信号，上述第二脉宽调制信号为用户在开启上述特定的背光调节模式后，在当次调整前历史作为调整背光强度的脉宽调制信号。
应当说明的是，本实施例中，上述背光增益值为上述占空比的调节比例。在其他实施例中，还可以直接采用占空比值作为背光增益值形成背光增益曲线。
进一步地，参照图3，基于本发明背光调节方法第一实施例，在本发明背光调节方法第三实施例中，上述步骤S10包括：
步骤S11，获取所述终端当前所处的地理位置信息；
步骤S12，根据所述地理位置信息获取所述地理位置信息预置时间段内对应的时刻信息；
步骤S13，根据所述时刻信息计算获得所述地理位置信息对应的背光增益曲线。
本实施例中，上述时刻信息包括晨光始时刻、日出时刻、白昼时长、日落时刻、昏影终时刻、黑夜时长等关键信息。上述预置时间段的时间长度可以根据实际需要进行设置，以下实施例中以一天为例作出详细说明。如图4所示，根据晨光始时刻t1、日出时刻t2、白昼时长△td、日落时刻t3、昏影终时刻t4、黑夜时长△tn计算出终端的背光增益曲线，其中t1、t2、t3、t4的值与终端所在的地理位置信息和当前的日期有关，并随终端的地理位置信息和当前日期的变化而动态变化；其中背光增益值x、y、z为预置值，且0<x<y<z；其中0时至t1时间段和t4至24时时间段表明终端所在地目前属于完全黑夜状态，这两个区间（即[0,t1]和[t4,24]区间）的背光增益值为x；t1至t2时间段为晨光始时刻至日出时刻之间的时段，其背光增益值由x迅速增加至y；t2至t2+1/4时间段为日出时刻至日出后十五分钟之间的时段，其背光增益值由y缓慢增加至z；t2+1/4至t3-1/4时间段为完全白天的时段，其背光增益值均为z；t3-1/4至t3时间段为日落时刻及其前十五分钟的时间段，其背光增益值由z缓慢降低至y；t3至t4时间段为日落时刻至昏影终的时间段，其背光增益值由y快速降低至x。
进一步地，参照图5，基于本发明背光调节方法第三实施例，在本发明背光调节方法第四实施例中，上述步骤S11包括：
步骤S111，当终端进入联网状态后，获取所述终端的IP地址；
步骤S112，根据所述IP地址获取所述终端的地理位置信息，所述地理位置信息包括经纬度信息。
本实施例中，上述终端可以通过3G/Wifi/Ethernet(无线网络/有线网络)进行联网。在终端联网后，可以获取终端的IP地址，根据该IP地址确定终端的经纬度信息，以确定终端当前所处的地理位置信息。可以理解的是，在其他实施例中，还可以采用其他方式确定终端的地理位置信息，例如可以通过GPRS定位系统获取终端的地理位置信息。
进一步地，参照图6，基于本发明背光调节方法第三实施例，在本发明背光调节方法第五实施例中，上述步骤S30之后还包括：
步骤S40，判断当前的时间点是否超出所述预置时间段；若是，则返回执行步骤S12；若否，则结束。
本实施例中，以上述预置时间段为一天为例作出详细说明。由于每一天的时刻信息都不一样，当当前的时间变为第二天时，则需要重新获取第二天的时刻信息，并生成第二天对应的背光增益曲线。然后根据重新生成的背光增益曲线对终端的背光强度进行调节。
本发明还提供一种背光调节装置，参照图7，在本发明背光调节装置第一实施例中，本发明提供的背光调节装置包括：
获取模块10，用于根据终端当前所处的地理位置信息获取对应的背光增益曲线，所述背光增益曲线包括各时间点与背光增益值的映射关系；
本发明提供的背光调节装置主要应用于智能终端的背光调节系统，用于对背光的强度进行调节。该终端可以包括电视机、手机和平板等等。具体地，上述地理位置信息可以为终端当前所处的经纬度信息。一定范围的经纬度可以对应一背光增益曲线。应当说明的是，上述背光增益曲线可以根据上述地理位置信息计算得到，也可储存在服务器端，由终端将当前所处的地理位置信息发送到服务器端，以获取当前地理位置信息对应的背光增益曲线。上述背光增益值反映背光强度，上述背光增益曲线表示各时间点对应的背光强度变化曲线。

调节模块30，用于根据所述背光增益值调节所述终端的背光强度。
本实施例中，在每一时间点上均对应一背光增益值，可以理解的是，不同时间点上的背光增益值可以相同，也可以不同；例如在白天时的背光增益值大于在晚上时的背光增益值。在获取到上述背光增益曲线后，可根据当前的时间点在背光增益曲线上查找该时间点对应的背光增益值，然后根据该背光增益值对终端的背光强度进行调节。具体地，该背光强度与环境光线强度有光，当环境光线强度越强时，需要控制背光强度也要越强（即在白天的时候背光增益值越大）；当环境光线强度越弱时，需要控制背光强度也要越弱（即在晚上的时候背光增益值越小）。
可以理解的是，可以在终端设置特定的背光调节模式，以控制终端是否根据时间点调节终端的背光强度。具体地，在未开启该特定的背光调节模式时，可以按照现有的背光调节方式进行背光控制，只有当用户开启特定的背光调节模式时，才根据当前的时间点查询所述背光增益曲线上对应的背光增益值，然后根据所述背光增益值调节所述终端的背光强度。
