具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的具体实施例仅仅用于解释本申请。为了便于描述，附图中仅示出了与本申请相关的部分。
正如背景技术中提到的对显示面板显示不均进行补偿的方法的补偿精度不高，出现这种问题的原因在于：具有透明显示区的显示面板对主屏和副屏(透明显示区)的亮度一致性的要求比较高，经测试当主副屏的亮度差大于2％时人 眼可以明显感知，因此显示面板在显示不均的补偿过程中，对图像获取装置采集的亮度数据精度要求较高。然而图像获取装置对显示面板的亮度数据采集精度为±3％，无法满足精度要求，导致显示面板的补偿精度不高。
基于上述问题，本实施例提供了以下解决方案：
本实施例提供了一种图像获取装置的调节方法，图1是本申请实施例提供的一种图像获取装置的调节方法的流程图，参考图1，该方法包括：
S110、采用图像获取装置获取显示面板的设定显示区域显示预设灰阶时的m1组第一测试画面数据；其中，m1为大于2的自然数。
图像获取装置为可以采集亮度数据的设备，如可以为相机或其他亮度采集设备。设定显示区域可以为显示面板的任意显示区域，示例性的可以为显示面板的副屏区，其中副屏区的透光率大于显示面板其他显示区的透光率。第一测试画面数据包括显示面板的设定显示区域显示预设灰阶时每一像素点的亮度值，示例性的设定显示区域包括n个子像素，则每一组第一测试画面数据包括n个子像素的亮度值。可以采用图像获取装置拍摄m1次，得到m1组第一测试画面数据。m1的数值可以根据需要设置，为提高补偿速度可以设置m1小于或等于10，示例性的m1可以为3-10。
S120、根据m1组第一测试画面数据的数据偏差分布情况确定图像获取装置的采集参数。
采集参数可以包括光圈大小和曝光时间等。在自然界与生产中，一些现象受到许多相互独立的随机因素的影响，如果每个因素所产生的影响都很微小时，总的影响可以看作是服从正态分布。正态分布随随机变量的平均数、标准差的大小与单位不同而有不同的分布形态。正态分布也叫常态分布，是连续随机变量概率分布的一种，自然界以及人类社会中的很多现象都符合正态分布，例如不同地区的人类身高，学生成绩的好坏、照相机传感器白噪声等均按正态形式分布。因此，当图像获取装置的采集参数设置合理，没有由于参数设置不合理带来的采集偏差时，图像获取装置采集的数据的偏差符合正态分布。
m1组第一测试画面数据的数据偏差可以通过以下方式求取：根据m1组第一测试画面数据计算每一子像素的亮度均值，得到n个子像素的亮度均值，然后将每一组测试画面数据中每一子像素的亮度值与相应的亮度均值作差得到m1组亮度偏差，该m1组亮度偏差即为m1组第一测试画面数据的数据偏差，根据数据偏差的分布情况调整图像获取装置的采集参数，直至图像获取装置采集的m1组测试画面数据的数据偏差符合正态分布。
S130、将确定的图像获取装置的采集参数配置入该图像获取装置。
本实施例采用图像获取装置获取显示面板的设定显示区域显示预设灰阶时的m1组第一测试画面数据，根据m1组第一测试画面数据的数据偏差分布情况确定图像获取装置的采集参数，使图像获取装置采集的数据符合图像获取装置的采集参数没有偏差时的实际误差分布情况，通过后续误差处理即可得到反映设定显示区域实际显示情况的数据，提高了图像获取装置的数据采集精度，从而使得根据图像获取装置采集的显示数据对显示面板进行补偿时具有较高的补偿精度。
图2是本申请实施例提供的另一种图像获取装置的调节方法的流程图，可选的，参考图2，该方法包括：
S110、采用图像获取装置获取显示面板的设定显示区域显示预设灰阶时的m1组第一测试画面数据；其中，m1为大于2的自然数。
S121、将每一发光子像素的s组第一测试画面数据取均值，得到第一测试数据集S(s1，s2，s3……sn)，将每一发光子像素的t组第一测试画面数据取均值，得到第二测试数据集T(t1，t2，t3……tn)。其中，n为显示面板的设定显示区域中发光子像素的个数；s1，s2，s3……sn分别为n个不同发光子像素的s组亮度数据的均值；t1，t2，t3……tn分别为n个不同发光子像素的t组亮度数据的均值；s+t＝m1。
显示画面可以是显示单色画面，也可以是显示灰阶图。当显示单色画面时显示面板上只有一种颜色的子像素发光，比如当显示面板显示红色画面时，显示面板上的红色子像素发光，其他颜色的子像素不发光。当显示面板显示灰阶图时，即所有子像素均发光，且显示灰阶相同。
在显示面板显示单色画面的情况下，显示画板的设定显示区域显示预设灰阶可以是显示面板中的单色子像素发出预设亮度的光，该预设亮度与单色子像素在显示预设灰阶的灰阶图时的亮度相同。当显示面板显示灰阶图时，显示画板的设定显示区域显示预设灰阶可以是显示画面显示预设灰阶的灰阶图。
当显示面板显示单色画面时，一个发光子像素即显示面板的一个子像素，如显示面板显示红色画面时，一个发光子像素为一个红色子像素。当显示面板显示灰阶图(即所有子像素均发光，且显示灰阶相同)时，一个发光子像素可以是显示面板的一个子像素，也可以是显示面板的一个像素单元，如一个像素单元包括红色子像素、绿色子像素和蓝色子像素。
此外，s和t的和等于m1，s和t的值可以相等。以一个发光子像素为例，其前s组第一测试画面数据分别为s11，s12，s13……s1s，后t组第一测试画面 数据分别为t11，t12，t13……t1t，则s组第一测试数据的均值s1＝(s11+s12+s13+……+s1s)/s，t组第一测试数据的均值t1＝(t11+t12+t13+……+t1t)/t。可以对m1组第一测试画面数据进行编号，从其中任意选择s组得到s组第一测试画面数据，剩余的t组作为t组第一测试画面数据，示例性的，可以直接选择第1-s组得到s组第一测试画面数据。
S122、计算S/T，并将S/T中等于1的数据剔除，得到第一样本数据。
S/T＝(s1/t1，s2/t2，s3/t3，……，sn/tn)。理想状态下，图像获取装置的精度非常高没有采集误差，则每一次采集的图像应该相同，s1/t1，s2/t2，s3/t3，……，以及sn/tn均为1，由于图像采集误差的存在导致每一次采集的图像略有不同，则s1/t1，s2/t2，s3/t3，……sn/tn中部分值不等于1，为了避免等于1的数据影响误差的分析，因此将等于1的数剔除，只剩余不等于1的部分数据，这样得到的第一样本数据更能对采集误差进行体现。
S123、计算第一样本数据中处于(u-p，u+q)区间内的样本数据的第一比例；其中，u为期望均值，p和q为预先设定的样本参数。
当图像获取装置的采集参数设置合理，没有由于参数设置不合理带来的采集偏差时，第一样本数据应大体符合正态分布。u，p和q可以根据图像获取装置的随机误差分布情况确定。示例性的，可以设置u＝1，p＝q＝0.1。
S124、当第一比例小于设定比例时，根据第一比例调节图像获取装置的采集参数，并采用调节参数后的图像获取装置重新采集第一测试画面数据，直至第一比例大于或等于设定比例。
由于图像获取装置在采集图像时是对显示面板进行逐行采集，显示面板显示画面时也是逐行显示，由于图像采集方式和显示方式的影响，使得图像获取装置在获取图像时，显示画面会出现多个横向条纹，对于整个显示面板而言，横向条纹变化时位置固定。但对于面积比较小的设定显示区域条纹在不同的时候可能位于设定显示区域的不同位置甚至会移出该设定显示区域，当图像获取装置的采集参数不合理时，图像获取装置拍摄的图像有时有条纹有时没条纹，且不同图像中条纹的位置可能不同，因此当拍摄的图像的个数较少时，每次采集的数据偏差较大，数据不符合设定的正态分布。此时，第一比例小于设定比例，图像获取装置的样本数据较分散。
采用调节参数后的图像获取装置重新采集m1组第一测试画面数据，重新计算S和T，以及S/T，根据新的S/T剔除等于1的样本值，得到新的第一样本数据，继续判断新的第一样本数据中处于(u-p，u+q)区间内的样本数据的第一比例是否大于或等于设定比例，当第一比例大于设定比例后，图像获取装置采集 的数据符合图像获取装置的实际误差分布情况，将此时的采集参数确定为图像获取装置最终的采集参数。此时图像获取装置的采集参数较为合理，使得图像获取装置每次拍摄可拍摄到设定显示区域的全部误差特征，使得图像获取装置每次拍摄的图像的重复性较好，通过后续误差处理即可得到反映设定显示区域实际显示情况的数据，根据该显示数据得到的补偿值的精度较高。示例性的，可以设置设定比例大于或等于60％，示例性的为70％，80％，90％，95％等。
S130、将确定的图像获取装置的采集参数配置入图像获取装置。
本实施例采用图像获取装置获取显示面板显示预设灰阶时的m1组第一测试画面数据，将每一发光子像素的前s组第一测试画面数据取均值，得到第一测试数据集S(s1，s2，s3……sn)，将每一发光子像素的后t组第一测试画面数据取均值，得到第二测试数据集T(t1，t2，t3……tn)，并将S/T中等于1的数据剔除，得到第一样本数据，通过剔除S/T中等于1的值，避免等于1的数据影响误差的分析，使得得到的第一样本数据更能对采集误差进行体现。并通过计算第一样本数据中处于(u-p，u+q)区间内的样本数据的第一比例，当第一比例小于设定比例时，根据第一比例调节图像获取装置的采集参数，并采用调节参数后的图像获取装置重新采集第一测试画面数据，直至第一比例大于或等于设定比例，使得图像获取装置的采集重复性较好，采集的数据符合图像获取装置的实际误差分布情况，通过后续误差处理即可得到反映设定显示区域实际显示情况的数据，使得图像获取装置具有较高的数据采集精度，根据图像获取装置获取的显示数据得到的显示面板的补偿值的精度较高。此外，本实施例仅需采集较少组的第一测试画面数据，通过对数据进行均值运算等处理，其可以较快地对图像获取装置的采集参数进行调整。
图3是本申请实施例提供的又一种图像获取装置的调节方法的流程图，可选的，参考图3，在采用图像获取装置获取显示面板的设定显示区域显示预设灰阶时的m1组第一测试画面数据之前，还包括：
S170、采用图像获取装置获取显示面板的设定显示区域显示预设灰阶时的m2组第二测试画面数据；其中，m2大于m1，且m2为自然数。
S180、将每一发光子像素的a组第二测试画面数据取均值，得到第三测试数据集A(a1，a2，a3……an)，将每一发光子像素的b组第二测试画面数据取均值，得到第四测试数据集B(b1，b2，b3……bn)。其中，a1，a2，a3……an分别为n个不同发光子像素的a组亮度数据的均值，b1，b2，b3……bn分别为n个不同发光子像素的b组亮度数据的均值；a+b＝m2。
S190、计算A/B，并将A/B中等于1的数据剔除，得到第二样本数据。
S200、根据第二样本数据确定u，p和q。
本实施例设置m2为较大的数值，示例性的m2可以设置为大于或等于100的整数，如设置为200，300，400或500等，使得第二测试画面数据的数据量较大，从而使得第二测试画面数据能够将设定显示区域的多种条纹偏差情况均能采集到，第二样本数据能够反映显示面板的设定显示区域的实际显示数据的误差分布情况。
通过将A/B中等于1的数据剔除，得到反映误差真实情况的第二样本数据。统计第二样本数据中每一数值点的个数，得到第二样本数据的分布图，横轴为数值，纵轴为个数。图4是本申请实施例提供的一种红色R、绿色G和蓝色B子像素的第二样本数据分布图，图5是本申请实施例提供的又一种R、G和B子像素的第二样本数据分布图。参考图4和图5，图4示出了预设灰阶为64灰阶时设定显示区域的R子像素、G子像素和B子像素的第二样本数据的分布图，图5示出了预设灰阶为255灰阶时设定显示区域的R子像素、G子像素和B子像素的第二样本数据的分布图。可以根据第二样本数据的分布图，确定样本均值，可以设置u＝样本均值，(u-p，u+q)可以设置为第二样本数据中数据量所占比例为设定比例的区间。
本实施例通过采集较大样本量的m2组第二测试画面数据，将每一发光子像素的前a组第二测试画面数据取均值，得到第三测试数据集A(a1，a2，a3……an)，将每一发光子像素的后b组第二测试画面数据取均值，得到第四测试数据集B(b1，b2，b3……bn)，并剔除A/B中等于1的值，得到第二样本数据，使得第二样本数据可以反映真实的误差情况，并根据第二样本数据的分布情况确定u，p和q。根据u，p和q以及设定比例调整图像获取装置的采集参数，使得图像获取装置采集的第一样本数据的分布形式与第二样本数据的分布形式相符，此时图像获取装置的采集参数较为合理，使得图像获取装置每次可拍摄到设定显示区域的全部误差特征，使得图像获取装置每次拍摄的图像的重复性较好，通过后续误差处理即可得到反映设定显示区域实际显示情况的数据，进一步提高图像获取装置的数据采集精度，根据图像获取装置获取的显示数据得到的显示面板的补偿值的精度较高。
可选的，调节方法还包括：
将每一发光子像素的m1组第一测试画面数据取均值得到第五测试数据集E(e1，e2，e3……en)，其中，e1，e2，e3……en为n个不同发光子像素的m1组亮度数据的均值；计算S/E和T/E，将S/T，S/E和T/E中等于1的数据剔除得到第一样本数据。
通过将S/T，S/E和T/E中等于1的数据剔除，使得得到的第一样本数据更能对采集误差进行体现，从而根据第一样本数据调节图像获取装置的采集参数时使得参数调整更为准确。
可选的，调节方法还包括：
将每一发光子像素的m2组第二测试画面数据取均值，得到第六测试数据集C(c1，c2，c3……cn)，其中，c1，c2，c3……cn为n个不同发光子像素的m2组亮度数据的均值；计算A/C和B/C，并将A/B、A/C和B/C中等于1的数据剔除，得到第二样本数据。
通过将A/B、A/C和B/C中等于1的数据剔除，使得得到的第二样本数据更能对图像获取装置的图像采集误差进行体现。
可选的，采用图像获取装置获取显示面板的设定显示区域显示预设灰阶时的m1组第一测试画面数据，包括：
采用图像获取装置获取显示面板的副屏区显示预设灰阶时的m1组第一测试画面数据；其中，显示面板包括主屏区和副屏区，副屏区的像素密度小于主屏区的像素密度。
副屏区为显示面板的透明显示区，设置为设置摄像头等光学传感器。副屏区的像素密度小于主屏区的像素密度，相同显示灰阶下，同颜色的子像素中，副屏区的子像素的发光亮度大于主屏区子像素的发光亮度，因此对显示面板进行补偿时，主屏区和副屏区需要分别进行数据采集和补偿值计算。然而，副屏区的面积较小，采用图像获取装置采集图像时容易出现较大的采集偏差。采用本实施例的方案调整图像获取装置的采集参数后采集副屏区的测试画面数据，使得图像获取装置每次拍摄可拍摄到副屏区的全部误差特征，使得图像获取装置每次拍摄的图像的重复性较好，通过后续误差处理即可得到反映副屏区实际显示情况的数据，根据该显示数据得到的补偿值的精度较高。
本实施例还提供了一种显示面板的补偿方法，图6是本申请实施例提供的一种显示面板的补偿方法的流程图，参考图6，该方法包括：
S310、采用本申请任意实施例的图像获取装置的调节方法调节图像获取装置的采集参数。
S320、采用调节参数后的图像获取装置采集多个不同预设灰阶下的测试画面数据。
S330、根据多个不同预设灰阶下的测试画面数据和目标亮度确定显示面板 的补偿值。
多个不同预设灰阶下的测试画面数据包括显示面板的待补偿区域的所有子像素的亮度值。采用参数调节完毕的图像获取装置采集多个不同灰阶下的测试画面数据，通过对该测试画面数据进行一定的处理可以得到设定显示区域的实际显示亮度数据，根据实际亮度数据和目标亮度可确定每一子像素的补偿值。
示例性的，可以采用参数调节完毕的图像获取装置采集f组测试画面数据，f小于m1，并求取f组测试画面数据的均值，根据均值和目标亮度求取显示面板每一子像素的补偿值。其中，f可以为2或3等。
本实施例还提供了一种图像获取装置的调节装置，图7是本申请实施例提供的一种图像获取装置的调节装置的示意图，参考图7，该装置包括：
