Description

色温调节方法及装置
本申请基于申请号为201510131391.5、申请日为2015/3/24的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开实施例涉及显示技术领域，特别涉及一种色温调节方法及装置。
背景技术
光源的色温是指光源发出的光的光色与绝对黑体的光色相同时，绝对黑体的温度。通常，低色温的光源发出暖光，高色温的光源发出冷光。
液晶屏包括包含LED(Light Emitting Diode，发光二极管)的背光模组、导光板和液晶，背光模组中不同LED发出的蓝光、红光和绿光分别经各自对应的液晶偏转照射到导光板上，导光板再将上述三种光进行混合，得到液晶屏中每个像素对应显示的颜色。可见，液晶屏的色温主要取决于LED的色温。若LED的色温不同，在液晶屏显示白色画面时，用户所感觉到的颜色也不同，因此，需要对液晶屏的色温进行调节。
由于厂家通常会根据LED的色温对LED进行区块划分，相同区块内的LED的色温比较接近，因此，可以将不同区块的LED交叉排列在液晶屏上，这样混合得到的液晶屏的色温比较一致。比如，将色温为6500k的LED区块和色温为8100k的LED区块交叉排列，混合得到的液晶屏的色温在7300k左右。
发明内容

若所述色坐标值不在所述目标色坐标区域内，则调整所述像素对应的N种基色光中至少一种的分量值，直至调整后所述像素的色坐标值在所述目标色坐标区域内后停止，N为正整数。
根据本公开实施例的第二方面，提供一种色温调节装置，包括：
坐标获取模块，被配置为在液晶屏显示白色画面时，获取所述液晶屏中像素的色坐标值；
坐标检测模块，被配置为检测所述坐标获取模块获取的所述色坐标值是否在目标色坐标区域内，所述目标色坐标区域是包含目标色坐标值的区域，所述目标色坐标值是根据所述液晶屏的目标色温计算得到的色坐标值；
分量调整模块，被配置为当所述坐标检测模块检测出所述色坐标值不在所述目标色坐标区域内时，调整所述像素对应的N种基色光中至少一种的分量值，直至调整后所述像素的色坐标值在所述目标色坐标区域内后停止，N为正整数。
根据本公开实施例的第三方面，提供一种色温调节装置，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为：
在液晶屏显示白色画面时，获取所述液晶屏中像素的色坐标值；
检测所述色坐标值是否在目标色坐标区域内，所述目标色坐标区域是 包含目标色坐标值的区域，所述目标色坐标值是根据所述液晶屏的目标色温计算得到的色坐标值；
若所述色坐标值不在所述目标色坐标区域内，则调整所述像素对应的N种基色光中至少一种的分量值，直至调整后所述像素的色坐标值在所述目标色坐标区域内后停止，N为正整数。
本公开的实施例提供的技术方案可以包括以下有益效果：
通过在液晶屏显示白色画面时，获取液晶屏中像素的色坐标值；检测色坐标值是否在目标色坐标区域内，目标色坐标区域是包含目标色坐标值的区域，目标色坐标值是根据液晶屏的目标色温计算得到的色坐标值；若色坐标值不在目标色坐标区域内，则调整像素对应的N种基色光中至少一种的分量值，直至调整后像素的色坐标值在目标色坐标区域内后停止，由于不同分量值的基色光相互混合会产生不同色温的光，因此，可以通过调整基色光的分量值，使得调整后各种基色光混合得到的色温等于目标色温，解决了将不同区块的LED交叉排列在液晶屏上，液晶屏的色温仍然不一致的问题，达到了提高液晶屏的色温一致性的效果。
应当理解的是，以上的一般描述和后文的细节描述仅是示例性的，并不能限制本公开。

在步骤101中，在液晶屏显示白色画面时，获取液晶屏中像素的色坐标值。

在步骤103中，若色坐标值不在目标色坐标区域内，则调整像素对应的N种基色光中至少一种的分量值，直至调整后像素的色坐标值在目标色坐标区域内后停止，N为正整数。
综上所述，本公开实施例提供的色温调节方法，通过在液晶屏显示白色画面时，获取液晶屏中像素的色坐标值；检测色坐标值是否在目标色坐标区域内，目标色坐标区域是包含目标色坐标值的区域，目标色坐标值是根据液晶屏的目标色温计算得到的色坐标值；若色坐标值不在目标色坐标区域内，则调整像素对应的N种基色光中至少一种的分量值，直至调整后像素的色坐标值在目标色坐标区域内后停止，由于不同分量值的基色光相互混合会产生不同色温的光，因此，可以通过调整基色光的分量值，使得调整后各种基色光混合得到的色温等于目标色温，解决了将不同区块的 LED交叉排列在液晶屏上，液晶屏的色温仍然不一致的问题，达到了提高液晶屏的色温一致性的效果。
图2是根据另一示例性实施例示出的一种色温调节方法的流程图，该色温调节方法应用于包含液晶屏的终端中，如图2所示，该色温调节方法包括如下步骤。
在步骤201中，在液晶屏显示白色画面时，获取液晶屏中像素的色坐标值。
色坐标用于在色度图上确定一个点，该点表示了该色坐标所对应的发光颜色。常用的色坐标的横轴为x轴，纵轴为y轴，此时色坐标值表示成(x，y)。比如，白炽灯色的色坐标值是(.463，.420)。
色温是根据色坐标计算出来的，与色坐标之间存在对应关系。比如，7300k的色温对应于(.30，.32)的色坐标值。其中，根据色坐标计算色温是比较成熟的技术，此处不作赘述。
由于本实施例需要调整液晶屏的色温一致性，在一种实现方式中，可以将调整液晶屏的色温转换为调整液晶屏中像素的色坐标值。本实施例中，在液晶屏显示白色画面时，通过测量设备测量像素的色坐标值。由于液晶屏的中心区域的发光比较均匀，因此，为了提高色坐标值的准确性，可以对液晶屏的中心区域中像素的色坐标值进行测量。
在步骤202中，检测色坐标值是否在目标色坐标区域内，目标色坐标区域是包含目标色坐标值的区域，目标色坐标值是根据液晶屏的目标色温计算得到的色坐标值。
本实施例中，终端可以预先设置液晶屏的目标色温，再根据目标色温计算目标色坐标值，再将液晶屏中像素的色坐标值调整到该目标色坐标值，从而保证液晶屏的色温一致性。
由于将像素的色坐标值精确地调整到目标色坐标值的难度较大，因此， 为了降低调整难度，可以基于目标色坐标值设置目标色坐标区域，用户对在该目标色坐标区域内的色坐标值所对应的色温的感知相同。
目标色坐标区域可以根据目标色坐标值计算得到。假设对色坐标值中x和y的允许误差都是0.005，且目标色坐标值是(.30，.32)，此时的目标色坐标区域是由(.295，.315)、(.305，.315)、(.295，.325)和(.305，.325)这四个顶点组成的所有坐标值。
在终端检测色坐标值是否在目标色坐标区域内是，若色坐标值在目标色坐标区域内，则确定不需要调整液晶屏的色温，结束流程，若色坐标值不在目标色坐标区域内，则确定需要调整液晶屏的色温，执行步骤203。
在步骤203中，若色坐标值不在目标色坐标区域内，则调整像素对应的N种基色光中至少一种的分量值，直至调整后像素的色坐标值在目标色坐标区域内后停止，N为正整数。
由于像素的发光颜色是由N种基色光混合得到的，且不同分量值的基色光混合得到的发光颜色不同，因此，像素的色温与基色光的分量值相关，若需要调整像素的色坐标值，可以调整像素对应的N种基色光中至少一种的分量值。其中，分量值用于指示一种基色光在发光颜色中所占的比例，且所有基色光的分量值之和等于1。
其中，调整像素对应的N种基色光中至少一种的分量值，包括：调整N种基色光中至少一种所对应的液晶的驱动电压值，驱动电压值与分量值呈正相关关系。
对于每一种基色光，该基色光的分量值由该基色光的灰阶决定，该基色光的灰阶由对应的液晶的偏转角度决定，而液晶的偏转角度由该液晶所对应的驱动电压控制，因此，调整基色光的分量值可以转换为调整该基色光所对应的液晶的驱动电压值。一个驱动电压控制一种基色光所对应的液晶。其中，驱动电压值越大，液晶的偏转角度越大，光的透过率越高，从 而使得基色光的灰阶越高，基色光的分量值越大。
其中，基色光为蓝光或红光或绿光，调整N种基色光中至少一种所对应的液晶的驱动电压值，包括：
1)根据色坐标值判断像素的色温是高于目标色温还是低于目标色温；
2)若像素的色温高于目标色温，则执行增加蓝光所对应的液晶的驱动电压值、减少红光所对应的液晶的驱动电压值、减少绿光所对应的液晶的驱动电压值中的至少一种操作；
3)若像素的色温低于目标色温，则执行减少蓝光所对应的液晶的驱动电压值、增加红光所对应的液晶的驱动电压值、增加绿光所对应的液晶的驱动电压值中的至少一种操作。
当像素的色温高于目标色温时，说明像素的发光颜色偏暖，此时需要执行增加蓝光所对应的液晶的驱动电压值、减少红光所对应的液晶的驱动电压值、减少绿光所对应的液晶的驱动电压值中的至少一种操作。比如，只增加蓝光所对应的液晶的驱动电压值，或，只减少红光所对应的液晶的驱动电压值，或，同时减少红光和绿光各自所对应的液晶的驱动电压值、或既增加蓝光所对应的液晶的驱动电压值，也同时减少红光和绿光各自所对应的液晶的驱动电压值等。
由于对液晶屏的亮度影响由大到小的基色光是绿色、红色和蓝色，因此，为了降低调整基色光的分量值对亮度的影响，可以优先增加蓝光所对应的液晶的驱动电压值，再减少红光和绿光各自所对应的液晶的驱动电压值。
在第一种实现方式中，执行增加蓝光所对应的液晶的驱动电压值、减少红光所对应的液晶的驱动电压值、减少绿光所对应的液晶的驱动电压值中的至少一种操作，包括：
1)增加蓝光所对应的液晶的驱动电压值；
2)在蓝光所对应的液晶的驱动电压值达到蓝光的极限电压值后，执行减少红光所对应的液晶的驱动电压值、减少绿光所对应的液晶的驱动电压值中的至少一种操作。
其中，在增加蓝光所对应的液晶的驱动电压值时，终端可以按照预定步长增加驱动电压值，比如，将预定步长设置为0.05v，则终端可以每次将蓝光所对应的液晶的驱动电压值增加0.05v，检测此时的色坐标值是否在目标色坐标区域内，若此时的色坐标值不在目标区域内，则继续将蓝光所对应的液晶的驱动电压值增加0.05v；若此时的色坐标值在目标区域内，则结束调整流程。或者，终端可以对预定步长进行收敛，按照收敛后的预定步长增加驱动电压值。比如，初始的预定步长是0.2v，终端将蓝光所对应的液晶的驱动电压值增加0.2v，检测此时的色坐标值是否在目标色坐标区域内，若此时的色坐标值不在目标区域内，且此时的色坐标值大于目标色坐标区域的最大值，则将预定步长设置为-0.1v，将蓝光所对应的液晶的驱动电压值减小0.1v；若此时的色坐标值不在目标区域内，且此时的色坐标值小于目标色坐标区域的最大值，则将预定步长设置为0.2v，继续将蓝光所对应的液晶的驱动电压值增加0.2v。
终端可以为每种基色光设置一个极限电压值，并限定基色光所对应的液晶的驱动电压值小于等于该极限电压值。当蓝光所对应的液晶的驱动电压值达到蓝光的极限电压值时，色坐标值还是不在目标色坐标区域内，此时需要执行减少红光所对应的液晶的驱动电压值、减少绿光所对应的液晶的驱动电压值中的至少一种操作。其中，减少红光所对应的液晶的驱动电压值和减少绿光所对应的液晶的驱动电压值的流程与上述增加蓝光所对应的液晶的驱动电压值的流程类似，此处不赘述。
当像素的色温低于目标色温时，说明像素的发光颜色偏冷，此时需要执行减少蓝光所对应的液晶的驱动电压值、增加红光所对应的液晶的驱动 电压值、增加绿光所对应的液晶的驱动电压值中的至少一种操作。比如，只减少蓝光所对应的液晶的驱动电压值，或，只增加红光所对应的液晶的驱动电压值，或，同时增加红光和绿光各自所对应的液晶的驱动电压值、或既减少蓝光所对应的液晶的驱动电压值，也同时增加红光和绿光各自所对应的液晶的驱动电压值等。
由于减小基色光的分量值会降低液晶屏的亮度，为了降低调整基色光的分量值对亮度的影响，可以优先增加红光或绿光各自所对应的液晶的驱动电压值，再减少蓝光所对应的液晶的驱动电压值。
在第二种实现方式中，执行减少蓝光所对应的液晶的驱动电压值、增加红光所对应的液晶的驱动电压值、增加绿光所对应的液晶的驱动电压值中的至少一种操作，包括：
1)执行增加红光所对应的液晶的驱动电压值、增加绿光所对应的液晶的驱动电压值中的至少一种操作；
2)在红光和绿光所对应的液晶的驱动电压值都达到各自的极限电压值后，减少蓝光所对应的液晶的驱动电压值。
其中，增加红光和绿光各自所对应的液晶的驱动电压值和减少蓝光所对应的液晶的驱动电压值的流程与增加蓝光所对应的液晶的驱动电压值的流程类似，此处不赘述。
在步骤204中，根据调整后基色光的分量值，调整基色光对应的伽马曲线，伽马曲线的调整趋势与分量值的调整趋势相同。
由于液晶屏的显示效果还与亮度和对比度相关，因此，在调整完基色光的分量值，使得像素的色坐标值位于目标色坐标区域内之后，终端还需要对调整的基色光的伽马曲线进行调整，从而调整液晶屏的亮度和对比度，以提高液晶屏的显示效果。比如，当调整了蓝光的分量值后，需要对蓝光的伽马曲线进行调整；当调整了绿光和红光的分量值后，需要分别对红光 的伽马曲线和绿光的伽马曲线进行调整。
其中，伽马曲线的调整趋势与分量值的调整趋势相同。比如，当增加基色光的分量值时，将伽马曲线向上平移；当减少基色光的分量值时，将伽马曲线向下平移。
根据伽马曲线的曲线特性可知，灰阶越小，亮度变化越小，灰阶越大，亮度变化越大，因此，可以分段设置伽马曲线的调整幅度，以提高调整伽马曲线的准确性。比如，对灰阶较小的伽马曲线段设置第一调整幅度，对灰阶较大的伽马曲线段设置第二调整幅度，且第一调整幅度小于第二调整幅度。其中，对伽马曲线的调整幅度可以是计算得到的数值，也可以是经验值，本实施例不作限定。
综上所述，本公开实施例提供的色温调节方法，通过在液晶屏显示白色画面时，获取液晶屏中像素的色坐标值；检测色坐标值是否在目标色坐标区域内，目标色坐标区域是包含目标色坐标值的区域，目标色坐标值是根据液晶屏的目标色温计算得到的色坐标值；若色坐标值不在目标色坐标区域内，则调整像素对应的N种基色光中至少一种的分量值，直至调整后像素的色坐标值在目标色坐标区域内后停止，由于不同分量值的基色光相互混合会产生不同色温的光，因此，可以通过调整基色光的分量值，使得调整后各种基色光混合得到的色温等于目标色温，解决了将不同区块的LED交叉排列在液晶屏上，液晶屏的色温仍然不一致的问题，达到了提高液晶屏的色温一致性的效果。
另外，通过根据调整后基色光的分量值，调整基色光对应的伽马曲线，伽马曲线的调整趋势与分量值的调整趋势相同，可以在调整了液晶屏的色温后，对液晶屏的亮度和对比度进行调整，以提高液晶屏的显示效果。
