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。
本发明实施例提供的调节屏幕色温的方法、装置、终端及计算机存储介质，通过检测终端的用户界面中的像素的RGB值，根据像素的RGB值获得用户界面的色调信息，根据预设的色调与色温的对应关系，获取与用户界面的色调信息相对应的色温值，最后根据获取的色温值调节屏幕的色温，使得终端可以随着用户界面的变化动态的调节屏幕的色温，以使屏幕的色温与用户界面相匹配，从而能够实现根据用户界面动态调节屏幕的色温，使用户界面显示的画面更加自然真实，增强了终端的显示效果，提升了用户体验。
以下通过具体实施例进行详细说明。
参见图1，提出本发明调节屏幕色温的方法第一实施例，所述方法包括以下步骤：
步骤S10：检测终端的用户界面中的像素的RGB值
终端可以实时的或每隔预设时间检测一次终端当前的用户界面中的像素的RGB值，优选地，当终端检测到当前的用户界面改变时，则进行一次检测。
终端可以只对用户界面中满足预设条件的像素的RGB值进行检测，如某一预设区域或用户指定区域的像素。本实施例优选对用户界面中所有像素的RGB值均进行检测。
所述RGB值，是指一个像素中所包含的红(Red)、绿(Green)、蓝(Blue)三个基准色的数值，不同的RGB值对应不同的颜色。例如，某一像素的颜色为黄色，则其对应的RGB值为(R255，G255，B0)，即红色值为255，绿色值为255，蓝色值为0。
步骤S11：对用户界面中所有像素的RGB值进行统计计算，获得用户界面中红绿蓝三个基准色的统计值
所述统计计算可以是求和计算或者平均值计算，对应的统计值则为求和值或平均值。例如，假设用户界面中包括N个像素，各像素对应的RGB值为(R1，G1，B1)、(R2，G2，B2)…(Rn，Gn，Bn)，对用户界面中所有像素的红绿蓝三个基准色进行求和运算，获得红色统计值为Rs＝(R1+R2+…+Rn)，绿色统计值为Gs＝(G1+G2+…+Gn)，蓝色统计值为Bs＝(B1+B2+…+Bn)。
在某些实施例中，只对用户界面中满足预设条件的像素的RGB值进行统计计算。例如，去除用户界面中的黑色、白色、纯绿色、纯红色或/和纯蓝色等像素后，剩下的像素则为满足预设条件的像素。
步骤S12：根据红绿蓝三个基准色的统计值计算用户界面中的红绿比值或/和蓝绿比值
用户界面中的红绿比值为Rs/Gs，蓝绿比值为Bs/Gs，用户界面中的红绿比值和蓝绿比值决定用户界面色调的冷暖程度。其中，红绿比值对应暖色调，红绿比值越大，则代表色调越暖；蓝绿比值对应冷色调，蓝绿比值越大，则代表色调越冷。
步骤S13：根据红绿比值或/和蓝绿比值获得用户界面的色调信息
色调信息可以以色调的冷暖等级来表示，如从冷到暖(从低到高)依次定义为1级～n级，将不同范围的红绿比值和蓝绿比值归类到不同的等级，随着红绿比值的逐渐增大、蓝绿比值的逐渐减小，色调冷暖等级逐级升高，从而根据用户界面中的红绿比值和蓝绿比值获得对应的冷暖等级。在某些实施例中，可以仅通过蓝绿比值和红绿比值中的其中一个值来定义色调的冷暖等级，如仅通过蓝绿比值来定义色调的冷暖等级，蓝绿比值越大，则对应的冷暖等级越低，从而根据用户界面中的蓝绿比值获得对应的冷暖等级；或者仅通过红绿比值来定义色调的冷暖等级，红绿比值越大，则对应的冷暖等级越高，从而根据用户界面中的红绿比值获得对应的冷暖等级。
色调信息也可以以色调值来表示，如将红绿比值与蓝绿比值的比值(红绿比值/蓝绿比值)或差值(红绿比值-蓝绿比值)作为色调值，色调值越大，对应的色调越暖，色调值越小，对应的色调越冷。
步骤S14：根据预设的色调与色温的对应关系，获取与用户界面的色调信息相对应的色温值
色调与色温的对应关系，可以是色调的冷暖等级与色温值的一一对应关系，也可以是色调值与色温值的一一对应关系。用户界面的色调信息所显示的色调越冷，则对应的色温值越小。即随着色调冷暖等级的升高，对应的色温值也增大，随着色调冷暖等级的降低，对应的色温值也减小；随 着色调值的增大，对应的色温值也增大，随着色调值的减小，对应的色温值也减小。
步骤S15：根据获取的色温值调节屏幕的色温
本实施例中，当用户界面的色调较冷时，则相应的将屏幕的色温降低，让颜色偏暖一些；当用户界面的色调较暖时，则相应的将屏幕的色温升高，让颜色偏冷一些。从而，通过相互综合、相互冲抵，使得用户界面的最终显示效果更加自然真实，避免图像颜色失真，提高了终端的显示效果。
参见图2，提出本发明调节屏幕色温的方法第二实施例，所述方法包括以下步骤：
步骤S20：检测终端的用户界面中的像素的RGB值
终端可以实时的或每隔预设时间检测一次终端当前的用户界面中的像素的RGB值，优选地，当终端检测到当前的用户界面改变时，则进行一次检测。
终端可以只对用户界面中满足预设条件的像素的RGB值进行检测，如某一区域的像素。本实施例优选对用户界面中所有像素的RGB值均进行检测。
所述RGB值，是指一个像素中所包含的红(Red)、绿(Green)、蓝(Blue)三个基准色的数值，不同的RGB值对应不同的颜色。例如，某一像素的颜色为天蓝色，则其对应的RGB值为(R135，G206，B235)，即红色值为135，绿色值为206，蓝色值为235。
步骤S21：根据每一像素的RGB值计算每一像素中的红绿比值或/和蓝绿比值
像素中的红绿比值为R/G，蓝绿比值为B/G，像素中的红绿比值和蓝绿比值决定像素色调的冷暖程度。其中，红绿比值对应暖色调，红绿比值越大，则代表色调越暖；蓝绿比值对应冷色调，蓝绿比值越大，则代表色调 越冷。
步骤S22：对用户界面中所有像素的红绿比值或/和蓝绿比值进行统计计算，获得红绿比值或/和蓝绿比值的统计值
所述统计计算可以是求和计算或者平均值计算，对应的统计值则为求和值或平均值。例如，假设用户界面中包括N个像素，各像素对应的RGB值为(R1，G1，B1)、(R2，G2，B2)…(Rn，Gn，Bn)；则各像素对应的红绿比值为R1/G1、R2/G2…Rn/Gn，对用户界面中所有像素的红绿比值进行求和运算，获得红绿比值的统计值为[R/G]＝(R1/G1+R2/G2+…+Rn/Gn)；各像素对应的蓝绿比值为B1/G1、B2/G2…Bn/Gn，对用户界面中所有像素的蓝绿比值进行求和运算，获得蓝绿比值的统计值为[B/G]＝(B1/G1+B2/G2+…+Bn/Gn)。
在某些实施例中，只对用户界面中满足预设条件的像素进行红绿比值或/和蓝绿比值的计算以及统计计算。例如，去除用户界面中的黑色、白色、纯绿色、纯红色或/和纯蓝色等像素后，剩下的像素则为满足预设条件的像素。
步骤S23：根据红绿比值或/和蓝绿比值的统计值获得用户界面的色调信息
色调信息可以以色调的冷暖等级来表示，如从冷到暖(从低到高)依次定义为1级～n级，将不同范围的红绿比值和蓝绿比值的统计值归类到不同的等级，随着红绿比值的统计值的逐渐增大、蓝绿比值的统计值的逐渐减小，色调冷暖等级逐级升高，从而根据用户界面的红绿比值的统计值和蓝绿比值的统计值获得对应的冷暖等级。在某些实施例中，可以仅通过蓝绿比值的统计值和红绿比值的统计值中的其中一个值来定义色调的冷暖等级，如仅通过蓝绿比值的统计值来定义色调的冷暖等级，蓝绿比值的统计值越大，则对应的冷暖等级越低，从而根据用户界面中的蓝绿比值的统计 值获得对应的冷暖等级；或者仅通过红绿比值的统计值来定义色调的冷暖等级，红绿比值的统计值越大，则对应的冷暖等级越高，从而根据用户界面中的红绿比值的统计值获得对应的冷暖等级。
色调信息也可以以色调值来表示，如将红绿比值的统计值与蓝绿比值的统计值的比值(红绿比值的统计值/蓝绿比值的统计值)或差值(红绿比值的统计值-蓝绿比值的统计值)作为色调值，色调值越大，对应的色调越暖，色调值越小，对应的色调越冷。
步骤S24：根据预设的色调与色温的对应关系，获取与用户界面的色调信息相对应的色温值
色调与色温的对应关系，可以是色调的冷暖等级与色温值的一一对应关系，也可以是色调值与色温值的一一对应关系。用户界面的色调信息所显示的色调越冷，则对应的色温值越小。即随着色调冷暖等级的升高，对应的色温值也增大，随着色调冷暖等级的降低，对应的色温值则减小；随着色调值的增大，对应的色温值也增大，随着色调值的减小，对应的色温值则减小。
步骤S25：根据获取的色温值调节屏幕的色温
本实施例中，当用户界面的色调较冷时，则相应的将屏幕的色温降低，让颜色偏暖一些；当用户界面的色调较暖时，则相应的将屏幕的色温升高，让颜色偏冷一些。从而，通过相互综合、相互冲抵，使得用户界面的最终显示效果更加自然真实，避免画面颜色失真，提高了终端的显示效果，提升了用户体验。
从而，本发明实施例提供的调节屏幕色温的方法，终端可以随着用户界面的变化动态的调节屏幕的色温，以使屏幕的色温与用户界面相匹配，如当用户界面的色调较冷时，则相应的将屏幕的色温降低，让颜色偏暖一些；当用户界面的色调较暖时，则相应的将屏幕的色温升高，让颜色偏冷 一些。从而，通过相互综合、相互冲抵，使得用户界面的最终显示效果更加自然真实，避免画面颜色失真，提高了终端的显示效果，提升了用户体验。
参见图3，提出本发明调节屏幕色温的方法第三实施例，所述方法包括以下步骤：
步骤S30：检测终端的用户界面中的像素的RGB值
终端可以实时的或每隔预设时间检测一次终端当前的用户界面中的像素的RGB值，优选地，当终端检测到当前的用户界面改变时，则进行一次检测。
终端可以只对用户界面中满足预设条件的像素的RGB值进行检测，如某一预设区域或用户指定区域的像素。本实施例优选对用户界面中所有像素的RGB值均进行检测。
本步骤，可对用户界面中的所有像素的RGB值进行统计计算，获得红绿蓝三个基准色的统计值；也可以根据每一像素的RGB值计算每个像素中的红绿比值和/或蓝绿比值，在对用户界面中所有像素的红绿比值和/或蓝绿比值进行统计计算，获取红绿比值的统计值和/或蓝绿比值的统计值，具体请参见前述的S11、和S21～S22来实现。
步骤S31：根据所述RGB值获得所述用户界面的色调信息
具体的，像素中的红绿比值为R/G，蓝绿比值为B/G，像素中的红绿比值和蓝绿比值决定像素色调的冷暖程度。其中，红绿比值对应暖色调，红绿比值越大，则代表色调越暖；蓝绿比值对应冷色调，蓝绿比值越大，则代表色调越冷。
步骤S32：根据预设的色调与色温的对应关系，获取与所述用户界面的色调信息相对应的色温值
色调信息可以以色调的冷暖等级来表示，如从冷到暖(从低到高)依 次定义为1级～n级，将不同范围的红绿比值和蓝绿比值的统计值归类到不同的等级，随着红绿比值的统计值的逐渐增大、蓝绿比值的统计值的逐渐减小，色调冷暖等级逐级升高，从而根据用户界面的红绿比值的统计值和蓝绿比值的统计值获得对应的冷暖等级。在某些实施例中，可以仅通过蓝绿比值的统计值和红绿比值的统计值中的其中一个值来定义色调的冷暖等级，如仅通过蓝绿比值的统计值来定义色调的冷暖等级，蓝绿比值的统计值越大，则对应的冷暖等级越低，从而根据用户界面中的蓝绿比值的统计值获得对应的冷暖等级；或者仅通过红绿比值的统计值来定义色调的冷暖等级，红绿比值的统计值越大，则对应的冷暖等级越高，从而根据用户界面中的红绿比值的统计值获得对应的冷暖等级。
色调信息也可以以色调值来表示，如将红绿比值的统计值与蓝绿比值的统计值的比值(红绿比值的统计值/蓝绿比值的统计值)或差值(红绿比值的统计值-蓝绿比值的统计值)作为色调值，色调值越大，对应的色调越暖，色调值越小，对应的色调越冷。
步骤S33：根据获取的色温值调节屏幕的色温
色调与色温的对应关系，可以是色调的冷暖等级与色温值的一一对应关系，也可以是色调值与色温值的一一对应关系。用户界面的色调信息所显示的色调越冷，则对应的色温值越小。即随着色调冷暖等级的升高，对应的色温值也增大，随着色调冷暖等级的降低，对应的色温值也减小；随着色调值的增大，对应的色温值也增大，随着色调值的减小，对应的色温值也减小。
从而，当用户界面的色调较冷时，则相应的将屏幕的色温降低，让颜色偏暖一些；当用户界面的色调较暖时，则相应的将屏幕的色温升高，让颜色偏冷一些。从而，通过相互综合、相互冲抵，使得用户界面的最终显示效果更加自然真实，避免图像颜色失真，提高了终端的显示效果。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行前述的调节屏幕色温的方法。
参见图4，提出本发明调节屏幕色温的装置一实施例，所述装置包括分析计算模块401和调节模块402，其中：
分析计算模块401：用于检测终端的用户界面中的像素的RGB值，根据RGB值获得用户界面的色调信息。
分析计算模块401可以实时的或每隔预设时间检测一次终端当前的用户界面中的像素的RGB值，优选地，当分析计算模块401检测到当前的用户界面改变时，则进行一次检测。分析计算模块401可以只对用户界面中满足预设条件的像素的RGB值进行检测，如某一预设区域或用户指定区域的像素。本实施例优选对用户界面中所有像素的RGB值均进行检测。
在某些实施例中，分析计算模块401对用户界面中所有像素的RGB值进行统计计算，获得用户界面中红绿蓝三个基准色的统计值，根据红绿蓝三个基准色的统计值计算用户界面中的红绿比值或/和蓝绿比值，根据红绿比值或/和蓝绿比值获得用户界面的色调信息。
具体的，所述统计计算可以是求和计算或者平均值计算，对应的统计值则为求和值或平均值。例如，假设用户界面中包括N个像素，各像素对应的RGB值为(R1，G1，B1)、(R2，G2，B2)…(Rn，Gn，Bn)，分析计算模块401对用户界面中所有像素的红绿蓝三个基准色进行求和运算，获得红色统计值为Rs＝(R1+R2+…+Rn)，绿色统计值为Gs＝(G1+G2+…+Gn)，蓝色统计值为Bs＝(B1+B2+…+Bn)。
可选地，分析计算模块401也可以只对用户界面中满足预设条件的像素的RGB值进行统计计算。例如，去除用户界面中的黑色、白色、纯绿色、纯红色或/和纯蓝色等像素后，剩下的像素则为满足预设条件的像素。
用户界面中的红绿比值为Rs/Gs，蓝绿比值为Bs/Gs，用户界面中的红绿比值和蓝绿比值决定用户界面色调的冷暖程度。其中，红绿比值对应暖色调，红绿比值越大，则代表色调越暖；蓝绿比值对应冷色调，蓝绿比值越大，则代表色调越冷。
色调信息可以以色调的冷暖等级来表示，如从冷到暖(从低到高)依次定义为1级～n级，将不同范围的红绿比值和蓝绿比值归类到不同的等级，随着红绿比值的逐渐增大、蓝绿比值的逐渐减小，色调冷暖等级逐级升高，从而分析计算模块401根据用户界面的红绿比值和蓝绿比值获得对应的冷暖等级。在某些实施例中，可以仅通过蓝绿比值和红绿比值中的其中一个值来定义色调的冷暖等级，如仅通过蓝绿比值来定义色调的冷暖等级，蓝绿比值越大，则对应的冷暖等级越低，从而分析计算模块401根据用户界面中的蓝绿比值获得对应的冷暖等级；或者仅通过红绿比值来定义色调的冷暖等级，红绿比值越大，则对应的冷暖等级越高，从而分析计算模块401根据用户界面中的红绿比值获得对应的冷暖等级。
色调信息也可以以色调值来表示，如分析计算模块401将红绿比值与蓝绿比值的比值(红绿比值/蓝绿比值)或差值(红绿比值-蓝绿比值)作为色调值，色调值越大，对应的色调越暖，色调值越小，对应的色调越冷。
在另一些实施例中，分析计算模块401根据每一像素的RGB值计算每一像素中的红绿比值或/和蓝绿比值，对用户界面中所有像素的红绿比值或/和蓝绿比值进行统计计算，获得红绿比值或/和蓝绿比值的统计值，根据红绿比值或/和蓝绿比值的统计值获得用户界面的色调信息。
具体的，像素中的红绿比值为R/G，蓝绿比值为B/G，像素中的红绿比值和蓝绿比值决定像素色调的冷暖程度。其中，红绿比值对应暖色调，红绿比值越大，则代表色调越暖；蓝绿比值对应冷色调，蓝绿比值越大，则代表色调越冷。
所述统计计算可以是求和计算或者平均值计算，对应的统计值则为求和值或平均值。例如，假设用户界面中包括N个像素，各像素对应的RGB值为(R1，G1，B1)、(R2，G2，B2)…(Rn，Gn，Bn)；则各像素对应的红绿比值为R1/G1、R2/G2…Rn/Gn，分析计算模块401对用户界面中所有像素的红绿比值进行求和运算，获得红绿比值的统计值为[R/G]＝(R1/G1+R2/G2+…+Rn/Gn)；各像素对应的蓝绿比值为B1/G1、B2/G2…Bn/Gn，分析计算模块401对用户界面中所有像素的蓝绿比值进行求和运算，获得蓝绿比值的统计值为[B/G]＝(B1/G1+B2/G2+…+Bn/Gn)。
可选地，分析计算模块401可以只对用户界面中满足预设条件的像素进行红绿比值或/和蓝绿比值的计算以及统计计算。例如，去除用户界面中的黑色、白色、纯绿色、纯红色或/和纯蓝色等像素后，剩下的像素则为满足预设条件的像素。
色调信息可以以色调的冷暖等级来表示，如从冷到暖(从低到高)依次定义为1级～n级，将不同范围的红绿比值和蓝绿比值的统计值归类到不同的等级，随着红绿比值的统计值的逐渐增大、蓝绿比值的统计值的逐渐减小，色调冷暖等级逐级升高，从而分析计算模块401根据用户界面的红绿比值的统计值和蓝绿比值的统计值获得对应的冷暖等级。在某些实施例中，可以仅通过蓝绿比值的统计值和红绿比值的统计值中的其中一个值来定义色调的冷暖等级，如仅通过蓝绿比值的统计值来定义色调的冷暖等级，蓝绿比值的统计值越大，则对应的冷暖等级越低，从而分析计算模块401根据用户界面中的蓝绿比值的统计值获得对应的冷暖等级；或者仅通过红绿比值的统计值来定义色调的冷暖等级，红绿比值的统计值越大，则对应的冷暖等级越高，从而分析计算模块401根据用户界面中的红绿比值的统计值获得对应的冷暖等级。
色调信息也可以以色调值来表示，如分析计算模块401将红绿比值的 统计值与蓝绿比值的统计值的比值(红绿比值的统计值/蓝绿比值的统计值)或差值(红绿比值的统计值-蓝绿比值的统计值)作为色调值，色调值越大，对应的色调越暖，色调值越小，对应的色调越冷。
调节模块402：用于根据预设的色调与色温的对应关系，获取与用户界面的色调信息相对应的色温值，根据获取的色温值调节屏幕的色温。
色调与色温的对应关系，可以是色调的冷暖等级与色温值的一一对应关系，也可以是色调值与色温值的一一对应关系。用户界面的色调信息所显示的色调越冷，则对应的色温值越小。即随着色调冷暖等级的升高，对应的色温值也增大，随着色调冷暖等级的降低，对应的色温值也减小；随着色调值的增大，对应的色温值也增大，随着色调值的减小，对应的色温值也减小。
从而，当用户界面的色调较冷时，调节模块402则相应的将屏幕的色温降低，让颜色偏暖一些；当用户界面的色调较暖时，调节模块402则相应的将屏幕的色温升高，让颜色偏冷一些。从而，通过相互综合、相互冲抵，使得用户界面的最终显示效果更加自然真实，避免图像颜色失真，提高了终端的显示效果。
本发明实施例提供的调节屏幕色温的装置，可以随着用户界面的变化动态的调节屏幕的色温，以使屏幕的色温与用户界面相匹配，如当用户界面的色调较冷时，则相应的将屏幕的色温降低，让颜色偏暖一些；当用户界面的色调较暖时，则相应的将屏幕的色温升高，让颜色偏冷一些。从而，通过相互综合、相互冲抵，使得用户界面的最终显示效果更加自然真实，避免画面颜色失真，提高了显示效果，提升了用户体验。
