Description
本公开涉及一种显示补偿方法、显示补偿模块和显示装置。
显示器已经逐渐被各种电子设备所广泛应用，例如：广泛应用在移动电话、个人数字助理(英文:Personal Digital Assistant,简称：PDA)、数码相机、计算机屏幕或笔记本计算机屏幕中，而大尺寸的显示器逐渐成为电子设备的重要特色之一。
当用户在通过显示器观察图像时，由于从用户到显示器上的各个点的距离并不完全相同，所以用户观察到的图像会产生失真。这是由于人类的眼睛在观察物体时相当于一个凸透镜，物体在眼睛里成像的大小决定于物体两端与眼睛的夹角,夹角越大在眼睛里成像就越大，夹角越小在眼睛里成像就越小，所以观测同等大小的物体，当观测者与该物体距离较近时可以呈现出较大的图像，当观测者与该物体距离较近时则呈现出较小的图像。而当显示器的尺寸很大或者用户到显示器的距离很近，则显示器上靠近用户的点与远离用户的点到用户位置的距离差会很大，所以用户观察到的图像会产生失真，影响用户对显示器显示效果的体验。

图1示出了用户对位于不同位置的同等大小的物体进行观查时的视角示意图。
参照图1所示，W1、W2、W3、W4、W5、W6和W7分别为大小相同的物体，OP点为观察者所在位置。物体W1-W7到P点的距离关系为：W1>W2＝W3>W4＝W5>W6＝W7，物体W1-W7的两端与OP点形成的夹角分别为α1、α2、α3、α4、α5、α6、α7，其大小关系为：α1>α2＝α3>α4＝α5>α6＝α7。
图2示出了图1中用户观察到的物体影像的示意图。
参照图2所示，物体W1-W7在观察者眼中分别显示为：P1、P2、P3、P4、P5、P6、P7,其大小关系为：P1>P2＝P3>P4＝P5>P6＝P7。
图3示出了本公开实施例提供的显示补偿方法的流程图。
参照图3所示，按照本公开的实施例提供显示补偿方法，该方法的工作过程描述如下：
在步骤S1中，接收待显示图像信号。
在步骤S2中，获取用户位置，用户位置为用户对于显示装置的相对位置。
图4示出了本公开实施例提供的获取用户位置的装置的示意性结构图。
示例性地，参照图4所示，可以通过在显示器的四个角上分别安装的用于获取用户影像的摄像头40获取用户位置。当获取用户位置时，摄像头40分别获取用户影像，然后通过对用户影像进行分析处理，获取用户位置。当然还可以使用其他方法来获取用户位置，例如：通过传感器、红外感应器等方式。
再次返回参见图3所示的显示补偿方法。在步骤S3中、根据用户位置对待显示图像信号进行补偿，获取补偿后的图像信号。
在步骤S4中、输出补偿后的图像信号。
本公开实施例提供的显示补偿方法，能够获取用户相对于显示器的相对位置，并根据用户相对于显示器的相对位置对待显示的图像信号进行补偿，所以可以避免因用户到显示器上的各个点的距离不同，导致用户观察到的图像产生图像失真，进而本公开实施例可以提高用户对显示器显示效果体验。
具体地，例如，在上述步骤S3中，根据用户位置对待显示图像信号进行补偿，获取补偿后的图像信号可包括以下子步骤：
S31、将待显示图像信号转化为多个待显示子图像块。
示例性地，待显示子图像块的面积可以与显示器上一个像素点的面积相等，即显示器上有多少个像素点则将待显示图像信号转化为多少个待显示子图像块。例如：显示的像素点的个数为1024*768，则将待显示图像信号转化为1024*768个待显示子图像块。当然还可以使用其他
方案将待显示图像信号转化为多个待显示子图像块。例如：沿列方向将待显示图像信号转化为多个矩形待显示子图像块，或者沿水平方向将待显示图像信号转化为多个矩形待显示子图像块。
S32、根据用户位置分别对多个待显示子图像块进行补偿，获取补偿后的子图像块。
具体地，步骤S32中，根据用户位置分别对多个待显示子图像块进行补偿，获取补偿后的子图像块，包括：
S321、根据用户位置获取每一个待显示子图像块到用户位置的距离，其中，待显示子图像块到用户位置的距离为待显示子图像块覆盖于显示器上的几何图形的中心点到用户位置的距离。
S322、根据距离以及预设公式分别对多个待显示子图像块进行补偿。
示例性的：预设公式可以为：
其中，a为进行补偿的待显示子图像块到用户位置的距离，b为到用户位置距离最大的待显示子图像块到用户位置的距离；P为补偿系数，0≤P≤1，B为到用户位置距离最大的待显示子图像块的面积大小；A为进行补偿的待显示子图像块补偿后的面积大小。
S33、根据补偿后的子图像块获取补偿后的图像信号。
图5示出本公开实施例提供的将待显示图像信号转化为多个待显示子图像块的示意图。
参照图5所示，图5中，OP表示用户位置，51表示进行补偿的待显示子图像块，52表示到用户位置距离最大的待显示子图像块，510表示显示器上待显示子图像块51覆盖于显示器的几何图形的中心点，520表示显示器上待显示子图像块52覆盖于显示器的几何图形的中心点。以显示器左下角O点位笛卡尔坐标系的原点，OP点到X、Y、Z轴上的投影分别为x、y、z，则OP点在笛卡尔坐标系的坐标为(x，y，z)；a表示510到OP的距离，b表示520到OP的距离。图5中以将待显示图像信号沿列方向划分为多个矩形待显示子图像块，用户位于显示器的左侧为例进行说明。
将待显示图像信号转化为多个待显示子图像块后，可通过显示器的
尺寸获取任一待显示子图像块的面积大小。然后将上述数据带入预设公式
中，即可获得进行补偿的待显示子图像块补偿后的面积大小。
上述公式中，因为b≥a,所以
由
可知，待显示子图像块距离用户位置距离越近，则待显示子图像块补偿后的大小越小。
图6示出本公开实施例提供的当用户位置位于显示器左侧时进行补偿后的显示信号的显示效果示意图。
参照图6，其中示出了用户位于显示器左侧时补偿后的图像信号的显示效果，显示图像由右向左逐渐减小。此外，图7示出了用户位置位于显示器右侧时补偿后显示信号的显示效果示意图；图8示出了用户位置位于显示器中心时补偿后显示信号的显示效果示意图；图9示出了用户位置位于显示器上侧时补偿后显示信号的显示效果示意图；图10示出了用户位置位于显示器下侧时补偿后显示信号的显示效果示意图。
参照图7、8、9、10所示，图中OP均代表用户位置，其中，图7为用户位于显示器右侧时补偿后的图像信号的显示效果，显示图像由左向右逐渐减小，图8为用户位于显示器中心时补偿后的图像信号的显示效果，显示图像由两边向中心逐渐减小，图9为用户位于显示器上侧时补偿后的图像信号的显示效果，显示图像由下向上逐渐减小，图10为用户位于显示器下侧时补偿后的图像信号的显示效果，显示图像由上向下逐渐减小。

本公开实施例提供的显示补偿模块，能够获取用户相对于显示器的相对位置，并根据用户相对于显示器的相对位置对待显示的图像信号进行补偿，所以可以避免因用户到显示器上的各个点的距离不同，导致用户观察到的图像产生图像失真，进而本公开实施例可以提高用户对显示器的显示效果的体验。
图12示出了本公开实施例提供的另一种显示补偿模块示意性结构图。
可选地，参照图12所示，补偿单元113可包括：
转化子单元1131，用于将待显示图像信号转化为多个待显示子图像块；
处理子单元1132，用于根据用户位置分别对多个待显示子图像块进行补偿，获取补偿后的子图像块；
获取子单元1133，用于根据补偿后的子图像块获取补偿后的图像信号。
可选地，处理子单元1132可以用于，根据用户位置获取每一个待显示子图像块到用户位置的距离，其中，待显示子图像块到用户位置的距离为待显示子图像块覆盖于显示器上的几何图形的中心点到用户位置的距离。
示例性地，预设公式可以包括：
其中，a为进行补偿的待显示子图像块到用户位置的距离，b为到用户位置距离最大的待显示子图像块到用户位置的距离；P为补偿系数，0≤P≤1，B为到用户位置距离最大的待显示子图像块的面积大小；A为进行补偿的待显示子图像块补偿后的面积大小。
本公开的一个实施例中提供一种显示装置，该显示装置包括上述任一实施例提供的显示补偿模块。
另外，显示装置可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本公开实施例提供的显示装置，能够获取用户相对于显示装置的相对位置，并根据用户相对于显示装置的相对位置对待显示的图像信号进行补偿，所以可以避免因用户到显示装置上的各个点的距离不同，导致用户观察到的图像会产生图像失真，进而本公开实施例可以提高用户对显示装置的显示效果的体验。
进一步地，显示装置包括显示面板，所述显示补偿模块位于所述显示面板上的非显示区域。
示例性地，可以将显示补偿模块的接收单元、补偿单元和获取单元设置于显示装置的黑矩阵区域，可以将显示补偿模块的检测单元设置于显示装置的边框上。显示补偿模块位于显示装置的非显示区域可以不影响显示装置的正常显示，此外，显示补偿模块位于所述显示面板上的非显示区域还可以在制作显示面板的工序中同时制作显示补偿模块，简化显示补偿模块的制作工艺流程。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
本申请要求于2015年5月20日递交的中国专利申请第201510259989.2号的优先权，在此全文引用该中国专利申请公开的内容作为本申请的一部分。
