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申请，并不用于限定本申请。
请参照图1，本申请的第一实施例中，该电视机显示图效控制方法包括以下步骤：
步骤S10，获取环境亮度信息，并根据环境亮度信息确定图像白平衡色温；
在本步骤中，环境亮度信息为当前环境的亮度值，电视机可以通过光感传感器感应当前环境的亮度值，光感传感器将感应到的当前环境的亮度值传送到电视机的主处理器（CPU），CPU将所得到的当前环境亮度值进行白平衡运算处理，进而得到现场环境的白平衡色温数值，自动将白平衡色温数值设定到电视机的显示图效中，以符合现场环境的色温。
根据光感传感器，可以得知当前的环境状态是明亮的还是黑暗的，当环境状态是明亮时，计算得到的白平衡色温值较大，将白平衡色温值设定到电视机的显示图效中后，让画面看起来不会暗；当环境状态是黑暗时，计算得到的白平衡色温值较小，将白平衡色温值设定到电视机的显示图效中后，画面看起来比较温和，达到护眼的目的。
需要说明的是，在本申请的一种实施例中，光感传感器是实时获取当前环境的亮度值，根据环境亮度值的变化，计算出实时白平衡色温并设定到电视机的显示图效中，使电视机的显示图效智能化适应人眼。
在另一种实施例中，电视机内可以存储不同的环境亮度值对应的图像白平衡色温，在光感传感器实时获取到当前环境的亮度值后，将查询到的与当前环境的亮度值相对应的图像白平衡色温设定到电视机的显示图效中。当无法查询到与当前环境的亮度值对应的图像白平衡色温时，再进行计算，并将得到的图像实时白平衡色温设定到电视机的显示图效中。
另外，根据环境亮度值实时计算图像的白平衡色温所需要的运算量较大，导致计算过程中占用的内存较多，因此，在电视机内预设一个环境亮度变化阈值，当光感传感器感应到的当前环境亮度值与上次感应到的环境亮度值之间的差值小于环境亮度变化阈值时，不对当前环境亮度值进行计算，不改变电视机的显示图效中设置的图像白平衡色温。
可以理解的是，在环境亮度值变化很小时，直接采用当前电视机设置的图像白平衡色温；当环境亮度值变化较大时，将根据环境亮度值计算出的图像白平衡色温设定到电视机的显示图效中。
步骤S20，获取电视机的屏幕亮度信息，并根据环境亮度信息和屏幕亮度信息确定图像背光亮度值；
具体地，获取的屏幕亮度信息包括电视机的屏幕的最大亮度、屏幕的最小亮度以及当前屏幕的背光亮度值。屏幕的最大亮度为电视机屏幕能够调节到的最大的亮度；屏幕的最小亮度为电视机屏幕能够调节到的最小的亮度；当前屏幕的背光亮度值为获取操作发生时的屏幕的背光值。
在本步骤中，利用电视机的屏幕亮度信息与环境亮度信息确定图像的背光亮度值。例如，当环境亮度值增大时，结合屏幕亮度信息确定得到的背光亮度值增大，将背光亮度值自动设定到电视机的显示图效中，即，电视机的当前背光亮度值会自动调节到较高值，让画面看起来较为明亮；当环境亮度值降低时，结合屏幕亮度信息确定得到的背光亮度值降低，将背光亮度值自动设定到电视机的显示图效中，即，电视机的当前背光亮度值会自动调节到较低值，让画面看起来比较温和。
在一实施例中，电视机内可以存储不同的环境亮度信息和电视机的屏幕亮度信息对应的图像背光亮度值，在获得的当前环境亮度值和当前屏幕的背光亮度值后，将查询到的与其对应的图像背光亮度值设定到电视机的显示图效中。当无法查询到与当前环境的亮度值和当前屏幕的背光亮度值对应的图像背光亮度值时，再进行计算，并将得到的图像背光亮度值设定到电视机的显示图效中。
另外，根据环境亮度信息和屏幕亮度信息计算图像背光亮度值所需要的运算量非常大，导致计算过程中占用的内存较多，则，在电视机内预设一个环境亮度变化阈值与屏幕背光亮度变化阈值，当光感传感器感应到的当前环境亮度值与上一刻感应到的环境亮度值之间的差值小于环境亮度变化阈值，且当前屏幕的背光亮度值与上一刻屏幕的背光亮度值之间的差值小于屏幕背光亮度变化阈值时，不对环境亮度信息与屏幕亮度信息进行计算，不改变电视机的显示图效中设置的图像白平衡色温与图像背光亮度值。
可以理解的是，在环境亮度值和当前屏幕的背光亮度值均变化很小时，直接采用当前电视机设置的图像白平衡色温与图像背光亮度值；当环境亮度值或者当前屏幕的背光亮度值变化较大时，根据环境亮度信息和屏幕亮度信息计算出图像白平衡色温与图像背光亮度值，并将其设定到电视机的显示图效中。
因此，利用屏幕亮度信息结合电视机所处环境来自动调节电视机的背光，无需用户手动操作即可完成背光亮度的调节过程，实现电视背光的智能动态调节，获得最佳观影效果的背光亮度值。
步骤S30，获取片源亮度信息，并根据片源亮度信息、环境亮度信息以及屏幕亮度信息确定图像亮度响应曲线；
具体地，在本实施例中的片源亮度信息为片源的当前信号图效的直方图。根据片源的当前信号图效的直方图，可以获取当前信号图效的状态，例如，识别当前信号画面是黑镜头画面、冰雪画面还是艳阳高照画面等，即，识别当前信号图效是亮画面还是暗画面。通过识别出来的当前画面的状态、亮画面占比、暗画面占比、环境亮度信息和屏幕亮度信息来确定图像亮度响应曲线。
在一种实施例中，电视机内可以存储不同的片源亮度信息、环境亮度信息和屏幕亮度信息对应的图像亮度响应曲线，直接查找获取到的图像亮度响应曲线，将图像亮度响应曲线设定到电视机的显示图效中；也可以预存不同的片源亮度信息、环境亮度信息和屏幕亮度信息对应的图像亮度响应曲线生成参数，并根据该生成参数生成图像亮度响应曲线。在查询不到片源亮度信息、环境亮度信息和屏幕亮度信息对应的图像亮度响应曲线时，再通过计算得到图像亮度响应曲线，并将其设定到电视机的显示图效中。
因此，根据不同的片源亮度信息、环境亮度信息和屏幕亮度信息得到不同的图像亮度响应曲线，将图像亮度响应曲线设定到电视机的显示图效中，使得不同的片源画面对应不同的亮度响应曲线，使电视机的显示图效在提高显示效果的同时更加适应人眼的需求。
需要说明的是，步骤S10、S20与S30之间并不存在运行的先后关系，即，同时获取到环境亮度信息、屏幕的亮度信息以及片源的亮度信息，再通过对三种信息的分别计算同时得到图像白平衡色温、图像背光亮度值以及图像亮度响应曲线，再进行步骤S40。
步骤S40，将图像白平衡色温、图像背光亮度值以及图像亮度响应曲线设定到电视机的显示图效中。
本实施例中，通过获取的环境亮度信息、电视机的屏幕亮度信息以及片源亮度信息，计算得到电视的图像白平衡色温、图像背光亮度值以及图像亮度响应曲线，自动将电视的图像白平衡色温、图像背光亮度值以及图像亮度响应曲线设定到电视机的显示图效中，使电视机的最终显示图效智能化适应人眼，电视机的显示图效自动进行调节，且在保护人眼的同时展现最佳的观影效果。
进一步地，请参照图2，基于第一实施例，在本申请的第二实施例中，所述步骤S20包括：
步骤S21，获取电视机的屏幕的最大亮度、屏幕的最小亮度以及当前屏幕的背光亮度值；
步骤S22，根据电视机的屏幕的最大亮度与电视机的屏幕的最小亮度计算出亮度转换系数；
步骤S23，根据环境亮度信息与当前屏幕的背光亮度值计算出环境转换系数；
步骤S24，根据环境亮度信息、环境转换系数以及亮度转换系数计算出图像背光亮度值。
需要说明的是，亮度转换系数为电视机的屏幕的最大亮度与屏幕的最小亮度的比值；环境转换系数为当前环境的亮度值与当前屏幕的背光亮度值的比值。同一台电视机的屏幕的最大亮度和最小亮度为固定值，则亮度转换系数是不变的，而环境转换系数是根据获取的当前环境的亮度值与当前屏幕的背光亮度值的不同而动态变化。
具体的，如果环境变亮，即，当前环境亮度值增大，则环境状态转换系数增大，根据环境亮度信息、亮度转换系数与环境转换系数计算得到的图像背光亮度值较大；当环境变暗时，即当前环境亮度值降低时，则环境状态转换系数降低，根据环境亮度信息、亮度转换系数与环境转换系数计算得到的图像背光亮度值较小。
进一步地，请参照图3，基于第一实施例，本申请的第三实施中，所述步骤S40具体包括：
步骤S50，判断计算出的图像的背光亮度值是否大于预设的第一背光亮度阈值；
步骤S41，若是，将图像白平衡色温、第一背光亮度阈值以及图像亮度响应曲线设定到电视机的显示图效中。
步骤S51，若否，判断计算出的图像的背光亮度值是否小于预设的第二背光亮度阈值；
步骤S42，若是，将图像白平衡色温、第二背光亮度阈值以及图像亮度响应曲线设定到电视机的显示图效中。
电视机内预存有图像的第一背光亮度阈值和第二背光亮度阈值，其中，第一背光亮度阈值大于第二背光亮度阈值。第一背光亮度阈值可以是图像能调整到的最大的背光亮度值，也可以是用户设定的适应用户自身观影要求的背光亮度值；第二背光亮度阈值可以是图像能调整到的最小的背光亮度值，也可以是用户设定的适应用户自身观影要求的背光亮度值。
具体的，在一实施例中，通过判断计算出的图像的背光亮度值是否大于预设的第一背光亮度阈值，在计算出的图像的背光亮度值大于第一背光亮度阈值时，用第一背光亮度阈值代替计算到的图像背光亮度值，即，将图像白平衡色温、第一背光亮度阈值以及图像亮度响应曲线设定到电视机的显示图效中，让电视机的显示图效在满足用户需求的同时，保护人眼并达到最佳观影效果。
在另一实施例中，还可以判断计算出的图像的背光亮度值是否小于预设的第二背光亮度阈值，在计算出的图像的背光亮度值小于第二背光亮度阈值时，用第二背光亮度阈值代替计算到的图像背光亮度值，即，将图像白平衡色温、第二背光亮度阈值以及图像亮度响应曲线设定到电视机的显示图效中，让电视机的显示图效在满足用户需求的同时，保护人眼并达到最佳观影效果。
在一实施例中，还可以先判断计算出的图像的背光亮度值是否大于预设的第一背光亮度阈值，若否，再判断计算出的图像的背光亮度值是否小于预设的第二背光亮度阈值，若是，将白平衡色温、第二背光亮度阈值以及图像亮度响应曲线设定到电视机的显示图效中；若否，将图像白平衡色温、计算出的图像背光亮度值以及图像亮度响应曲线设定到电视机的显示图效中。
可以理解的是，只有计算出的图像的背光亮度值小于第一背光亮度阈值且大于第二背光亮度阈值时，才将图像白平衡色温、计算出的图像背光亮度值以及图像亮度响应曲线设定到电视机的显示图效中。
本实施例中，利用屏幕亮度信息结合电视机所处环境信息来自动调节电视机的背光，无需用户手动操作即可完成背光亮度的调节过程，实现电视背光的智能动态调节，且获得最佳观影效果的背光亮度值。
进一步地，请参照图4，基于第二实施例，本申请的第四实施例中，所述步骤S30包括：
步骤S31，获取片源的当前信号图效的直方图；
步骤S32，根据当前信号图效的直方图计算出画面平均亮度；
步骤S33，根据当前信号图效的直方图与画面平均亮度计算出平均图像电平；
步骤S34，根据平均图像电平、环境亮度信息、电视机的屏的最大亮度以及亮度转换系数计算出图像亮度响应曲线。
可以理解的是，片源亮度信息是指片源的当前信号图效的直方图。根据片源的当前信号图效的直方图计算出画面平均亮度，从而得到画面的明亮程度。根据当前信号图效的直方图与画面平均亮度计算出平均图像电平，平均图像电平高，是指大部分图像变得具有亮度成分，即，画面的亮画面占比高；相反的，平均图像电平低，是指黑色所占图像的面积变得较多，即，画面的暗画面占比高。
本实施例中，根据平均图像电平、环境亮度值、电视机的屏的最大亮度以及亮度转换系数计算出亮度响应曲线，将亮度响应曲线设定到电视机的显示图效中，相当于对原有的亮度响应曲线进行了微调，在提升电视机的显示图效的观赏效果的同时保护人的眼睛。
进一步地，请参照图5，基于上述实施例，在本申请的第五实施例中，所述电视机显示图效控制方法包括：
步骤S10，获取环境亮度信息，并根据环境亮度信息确定图像白平衡色温；
步骤S21，获取电视机的屏幕的最大亮度、屏幕的最小亮度以及当前屏幕的背光亮度值；
步骤S22，根据电视机的屏幕的最大亮度与电视机的屏幕的最小亮度计算出亮度转换系数；
步骤S23，根据环境亮度信息与当前屏幕的背光亮度值计算出环境转换系数；
步骤S24，根据环境亮度信息、环境转换系数以及亮度转换系数计算出图像背光亮度值；
步骤S31，获取片源的当前信号图效的直方图；
步骤S32，根据当前信号图效的直方图计算出画面平均亮度；
步骤S33，根据当前信号图效的直方图与画面平均亮度计算出平均图像电平；
步骤S34，根据平均图像电平、环境亮度信息、电视机的屏的最大亮度以及亮度转换系数计算出图像亮度响应曲线；
步骤S40，将图像白平衡色温、图像背光亮度值以及图像亮度响应曲线设定到电视机的显示图效中。
具体地，在电视机开机播放后，电视机自动获取到当前环境亮度值、电视机的屏幕的最大亮度、屏幕的最小亮度、当前屏幕的背光亮度值以及片源的当前信号图效的直方图；通过当前环境亮度值确定图像白平衡色温；通过当前环境亮度值、电视机的屏幕的最大亮度、屏幕的最小亮度以及当前屏幕的背光亮度值确定图像背光亮度值；通过当前环境亮度值、电视机的屏幕的最大亮度、屏幕的最小亮度以及片源的当前信号图效的直方图确定出图像亮度响应曲线；将图像白平衡色温、图像背光亮度值以及图像亮度响应曲线设定到电视机的显示图效中，使电视机的最终显示图效智能化适应人眼，在保护人眼的同时展现最佳的观影效果。
另外，在另一种实施例中，如果用户在一种环境下对电视机自动调节的显示图效的显示效果不满意，可以对电视机的图像白平衡色温与图像的背光亮度值进行手动调节，电视机的处理器自动对调节后的图像白平衡色温与图像的背光亮度值进行存储，在再一次处于同样的环境下时，用存储好的图像白平衡色温与图像的背光亮度值代替计算得到的图像白平衡色温与图像的背光亮度值，即将存储好的图像白平衡色温、存储好的图像的背光亮度值以及计算得到的图像亮度曲线设定到显示图效中。此外，用户也可以只对图像白平衡色温与图像的背光亮度值之中的一种进行调节，同样将调节后的数据存储，在再一次处于同样的环境下时，将其设定到电视机的显示图效中。
需要说明的是，本申请的第一至第四实施例中的显示图效的控制方法不仅仅适应于电视机，还可以适应于具有播放显示功能的其他设备中，如电脑、手机、平板等。
此外，为实现上述目的，请参照图6，本申请还提供一种电视机，所述电视机包括存储器100、处理器200、光感传感器300及存储在存储器上并可在处理器上运行的计算机程序，处理器执行计算机程序时实现如上第一实施例中的电视机显示图效控制方法的步骤，具体包括：
