 本发明的实施方式
为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
目前市场上的LCD、OLED、LED等显示设备或多或少都存在视角不佳的问题，尤其是当用户位于显示设备的斜方向观看时，由于视角存在倾斜，导致显示设备上的图像显示效果比较差，并且对于LCD液晶显示器表现得尤为突出。经研究表明，通过对视角的改善来提高显示效果的方式有很多，其中主要有：偏光片工艺及功能优化、RGB像素阵列物理分区、像素点gamma（显示器参数）补偿等，这些方法在一定程度上能够实现显示设备的色度视角改善，但需要牺牲显示设备其他性能（如，分辨率、对比度等），且色度视角提高的幅度有限，很难实现全视角改善。
因此，为了解决上述问题，本实施例提供一种图像显示方法，通过本实施例的方法可显示设备可以根据每一个像素点所对应的目标显示灰阶数据来对待显示图像进行显示，有助于保证该待显示图像中的每一个像素点都以最合适的灰阶数据进行显示，提高不同视角下的显示效果。具体实施时，本实施例首先获取待显示图像中每一个像素点所对应的视角。接着，本实施例可根据所述视角，获取与所述视角所对应的目标显示灰阶数据。由于本发明获取到了所述待显示图像中的每一个像素点对应的视角，以及每一个视角所对应的目标显示灰阶数据，这样显示图像时，就可以使用每一个视角所对应的目标显示灰阶数据进行显示。
举例说明，当电视机需要进行图像显示时，电视机会获取待显示图像上的每一个像素点的视角。比如，获取到A像素点的视角为1°、B像素点的视角为1.5°等。当获取到每一个像素点的视角后，电视机就会获取每一个视角所对应的目标显示灰阶数据，在本例中，目标显示灰阶数据是像素RGB基色所对应的灰阶数据，比如（155，90，200）。当得到每个视角对应的目标显示灰阶数据后，电视机就可以基于每一个视角对应的目标显示灰阶数据来对该待显示图像进行显示，这样就可以保证该待显示图像中每一个像素点均可以用最为合适的目标显示灰阶数据来进行显示，从而提高了图像显示质量，并且还对显示设备的色度视角进行了改善。
示例性方法
本实施例中的图像显示方法可应用于显示设备中，该显示设备具有显示屏，比如电视机、电脑、平板等智能终端产品。所述显示设备包括但不限于LCD、OLED、QLED、mini_LED、micro_LED等显示设备。具体实施时，如图1中所示，本实施例中的所述图像显示方法包括以下步骤：
步骤S100、获取待显示图像中每一个像素点所对应的视角。
在本实施例中，本实施例所要实现的是改善现有的显示设备因为各个像素点视角的差异而影响显示效果的问题。为了提高显示效果，本实施例控制显示设备在进行图像显示时，基于各个像素点的灰阶数据来对图像进行显示。为此，本实施例首先需要确定待显示图像中每一个像素点所对应的视角，以便在后续步骤中获取各个视角所对应的目标显示灰阶数据。
在一种实现方式中，如图1中所示，所述步骤S100具体包括如下步骤：
步骤S101、获取所述显示设备上的中心位置，并将所述中心位置作为垂直视角位置；
步骤S102、遍历所述待显示图像中的每一个像素点的位置信息，其中，所述待显示图像的尺寸信息与所述显示设备上的显示屏的尺寸信息匹配；
步骤S103、根据所述位置信息与所述垂直视角位置，计算每一个像素点与所述垂直视角位置之间的倾斜角度，并将所述倾斜角度作为所述视角。
具体实施时，由于用户最佳的观看视角位置是位于显示设备正前方所在的位置处，该位置在显示设备上的投影即为该显示设备的中心位置。而待显示图像中的很多像素点都会与该中心位置之间存在偏离，因此就导致了每个像素点都会存在不同的视角。因此，为了可以准确获取到每一个像素点的视角，本实施实现获取显示设备上的中心位置，该中心位置即为所述显示设备的显示屏上的中心位置，该中心位置的正前方即为最佳观影位置，当用户处于最佳观影位置上进行观看时，此时用户的视线是与显示设备的显示屏垂直的。因此，所述显示设备的中心位置即为垂直视角位置。当获取显示设备的中心位置后，本实施例开始遍历该待显示图像中的像素点，在本实施例中，所述待显示图像是与显示设备的显示屏匹配的，也就是说待显示图像的尺寸信息与所述显示屏的尺寸信息相同的。比如，当显示屏的尺寸信息为1920*1080mm，则待显示图像的尺寸信息也为1920*1080mm。当遍历到每一个像素点后，本实施例就获取该像素点的位置信息，当得到每个像素点的位置信息后，本实施例即可根据每一个像素点的位置信息与所述垂直视角位置，得到每一个像素点的位置信息与垂直视角位置之间的倾斜角度，该倾斜角度即为每一个像素点的视角。具体实施时，本实施例在得到每一个像素点的位置信息以及所述垂直视角位置后，在垂直视角位置的正前方设置一固定点，分别以该固定点为起点，连接每一个像素点的位置以及垂直视角位置，这样垂直视角位置与该固定点之间的连线是垂直显示设备的，每一个像素点的位置与该固定点之间的连线是相对于垂直视角位置与该固定点之间的连线倾斜的，并且均相较于该固定点上。这样就可以基于每一个像素点的位置与该固定点之间的连线与垂直视角位置与该固定点之间的连线，得到每一个像素点与所述垂直视角位置之间的倾斜角度，从而得到每一个像素点的视角。
比如，当需要确定电视机上每一个像素点的位置信息时，本实施例首先获取电视机上的中心位置，并将该中心位置作为垂直视角位置A。接着，获取待显示图像上每一个像素点的位置信息，比如像素点1的位置信息为位置a，像素点2的位置信息为位置b。接着，在垂直视角位置A的正前方设置一固定点X，然后将所述固定点X分别与位置a、位置b以及垂直视角位置A连接，此时固定点X与垂直视角位置A的连线是垂直与电视机的，而固定点X与位置a的连线是和固定点X与垂直视角位置A的连线呈一倾斜角度1的，该倾斜角度1即为像素点1的视角。固定点X与位置b的连线，均是和固定点X与垂直视角位置A的连线呈一倾斜角度2的，该倾斜角度2即为像素点2的视角。
在其他实施例中，所述垂直视角位置不一定是所述显示设备的中心位置，在具体应用时，可根据显示设备的摆放位置以及摆放角度，自主设置显示设备上的其他位置处的点作为所述垂直视角位置，本实施例并不对此进行限定。
步骤S200、根据所述视角，获取与所述视角所对应的目标显示灰阶数据。
当得到每一个像素点所对应的视角后，本实施例即可根据每一个视角，获取与视角所对应的目标显示灰阶数据。在本实施例中，目标显示灰阶数据即为像素RGB基色的灰阶数据，灰阶数据为0-255。由于本实施例得到了每一个视角的目标显示灰阶数据，这样即便该视角对应的像素点的位置与垂直视角位置之间间隔较远，也同样可以得到该视角最为合适的目标显示灰阶数据，这样在进行图像显示时，可以提高显示质量。
在一种实现方式中，如图2中所示，所述步骤S200具体包括：
步骤S201、获取预设的若干视角和显示灰阶数据之间的映射关系；
步骤S202、根据所述若干视角与显示灰阶数据之间的映射关系，确定所述视角所对应的所述目标显示灰阶数据。
具体实施时，本实施例在获取到每一个像素点的视角后，将该视角与预设的所述若干视角与显示灰阶数据之间的映射关系进行匹配。在本实施例中，所述若干视角与显示灰阶数据之间的映射关系可设置成一个灰阶数据查找表。由于该灰阶数据查找表中设置有不同视角以及显示灰阶数据之间的映射关系，因此当将每一个像素点的视角与该灰阶数据查找表进行匹配时，就可以从该灰阶数据查找表中找到与该视角所对应的目标显示灰阶数据。为了改善显示效果，在本实施例中，目标显示灰阶数据为两个灰阶的组合数据，即RGB基色中的R基色对应的灰阶数据、G基色对应的灰阶数据、B基色对应的灰阶数据均为两个灰阶的组合，比如为高灰阶与低灰阶的组合，这样当显示设备使用该目标显示灰阶数据进行图像显示时，可基于该组合的灰阶数据进行分时显示，有利于提高各个像素点的显示效果。
在一种实现方式中，本实施例中的所述若干视角和显示灰阶数据之间的映射关系（即灰阶数据查找表）是预先设置，并且存储在所述显示设备中，以便在需要的时候进行调用。具体地，本实施例在设置灰阶数据查找表时，首先采用预设的色彩分析设备（比如CA410色彩分析仪）分别获取不同视角下的RGB基色在0-255的灰阶数据范围内的亮度数据，并得到不同视角下所述RGB基色的亮度数据与灰阶数据之间的映射关系表。比如，在该映射关系表中，存储有0°视角（即垂直视角）的RGB基色的亮度数据与灰阶数据之间的对应关系、10°视角（即倾斜视角）的RGB基色的亮度数据与灰阶数据之间的对应关系、20°视角（即倾斜视角）的RGB基色的亮度数据与灰阶数据之间的对应关系等等。当得到该映射关系表后，本实施例即可获取垂直视角下所述RGB基色的第一灰阶数据以及对应的第一亮度数据。也就是获取到0°视角下RGB基色的第一灰阶数据以及对应的第一亮度数据。比如，获取到的垂直视角下的RGB基色的第一灰阶数据为（RGB：240，180，160），对应的第一亮度数据为195.4cd/m2。
接着，本实施例对所述垂直视角下所述RGB基色的第一灰阶数据进行拆分，得到所述垂直视角下所述RGB基色的第一灰阶数据所对应的第一显示灰阶组合数据，此时拆分的目的就是为了将第一灰阶数据拆分成两个灰阶数据，从而得到该第一显示灰阶组合数据。此时，所述垂直视角下所述RGB基色的第一灰阶数据与所述第一显示灰阶组合数据均对应所述第一亮度数据。也就是说，即便对第一灰阶数据拆分成了第一显示灰阶数据，其所对应的亮度数据不变，还是与第一亮度数据对应。
在进行拆分时，本实施例可对该RGB基色的第一灰阶数据整体进行拆分，该可以分别对该RGB基色中的R基色对应的灰阶数据、G基色对应的灰阶数据以及B基色对应的灰阶数据进行拆分。具体如下，当本实施例对该RGB基色的第一灰阶数据整体进行拆分时，本实施例首先得到所述垂直视角下所述RGB基色的整体灰阶数据，比如（RGB：240，180，160）。接着，对所述整体灰阶数据进行整体拆分，得到所述垂直视角下所述RGB基色的第一显示灰阶组合数据，其中，所述第一显示灰阶组合数据包括有R基色对应的灰阶组合数据、G基色对应的灰阶组合数据以及B基色对应的灰阶组合数据，且所述R基色对应的灰阶组合数据、所述G基色对应的灰阶组合数据以及所述B基色对应的灰阶组合数据均包括两个灰阶数据。比如，将（RGB：240，180，160），拆分为（RGB：108/212,84/156,74/144），即得到的第一显示灰阶数据。
而当本实施例采用分别对该RGB基色中的R基色对应的灰阶数据、G基色对应的灰阶数据以及B基色对应的灰阶数据的方式进行拆分时，本实施例首先得到所述垂直视角下所述RGB基色的整体灰阶数据，分别对R基色对应的灰阶数据、G基色对应的灰阶数据以及B基色对应的灰阶数据进行拆分，得到R基色对应的灰阶组合数据、G基色对应的灰阶组合数据以及B基色对应的灰阶组合数据，其中，所述R基色对应的灰阶组合数据、所述G基色对应的灰阶组合数据以及所述B基色对应的灰阶组合数据均包括两个灰阶数据。再根据所述R基色对应的灰阶组合数据、G基色对应的灰阶组合数据以及B基色对应的灰阶组合数据，得到所述垂直视角下的第一显示灰阶组合数据。比如将R基色的灰阶数据：200灰阶拆分为150灰阶和90灰阶。将G基色的灰阶数据：200灰阶拆分为150灰阶和90灰阶。将B基色的灰阶数据：200灰阶拆分为150灰阶和90灰阶，得到的第一显示灰阶数据即为（RGB：150/90,150/90,150/90）。在本实施例中，当对第一灰阶数据进行拆分时，可采用定值拆分，比如上述将（RGB：200,200,200）拆分为（RGB：150/90,150/90,150/90）；也可以采用不定值拆分，比如上述将（RGB：240，180，160）拆分为（RGB：108/212,84/156,74/144）。
当然，本实施例在计算所述垂直视角下所有的RGB基色的第一灰阶数据所对应的第一显示灰阶组合数据时，可先计算部分垂直视角下的第一显示灰阶组合数据，然后通过插值或者拟合的方法计算剩下的垂直视角下的第一显示灰阶组合数据。当得到所述垂直视角下所有的RGB基色的第一灰阶数据所对应的第一显示灰阶组合数据后，本实施例中映射关系表中所反映的映射关系即为：垂直视角→RGB基色的第一灰阶数据→第一亮度数据→第一显示灰阶组合数据。由于本实施例的显示设备存在倾斜视角的原因，而如果基于拆分后得到的灰阶组合数据来进行显示可以提高显示效果，改善因视角倾斜导致的观看效果不佳的问题。为此，本实施例需要获取其他的视角下各个像素RGB基色的显示灰阶组合数据。具体地，本实施例获取不同视角下所述RGB基色的第二灰阶数据以及对应的第二亮度数据，此时所获取的视角为除去0°视角（即垂直视角）以外的所有视角，这些视角都属于倾斜视角。而为了保证显示效果，则需要尽量保证显示设备的显示屏上各个区域的亮度相同或者相近。因此，本实施例基于亮度相同原则，根据所述第二亮度数据与所述映射关系表，确定所述垂直视角下，与所述第二亮度数据相同或者与所述第二亮度数据之间呈预设比例的第一亮度数据。也即是说，本实施例需要找到每一个倾斜视角所对应的亮度数据，在垂直视角下与之相同或者相近的亮度数据。当确定出与所述第二亮度数据相同或者等比例相同的第一亮度数据后，本实施例就将所述第一亮度数据所对应的第一显示灰阶组合数据作为所述不同视角下所述RGB基色的第二显示灰阶组合数据，因此就得到不同视角下所述RGB基色的第二亮度数据、第二灰阶数据以及第二显示灰阶数据之间的目标映射关系，即不同视角（即各个倾斜视角）→第二灰阶数据→第二亮度数据→第二显示灰阶数据。换句话说，本实施例是先创建映射关系A：垂直视角--RGB基色的第一灰阶数据→第一亮度数据→第一显示灰阶组合数据。然后再获取某一个倾斜视角的第二亮度数据和第二灰阶数据，基于亮度相同的原则，从映射关系A中找到与第二亮度数据相同或者等比例相同的第一亮度数据，进而再从映射关系A中找到该第一亮度数据对应的第一显示灰阶组合数据，因此，找到的第一显示灰阶组合数据即就作为该倾斜视角下的第二显示灰阶组合数据，因此创建的映射关系B即为：倾斜视角→RGB基色的第二灰阶数据→第二亮度数据→第二显示灰阶组合数据（该第二显示灰阶组合数据是基于映射关系A确定的）。
举例说明，创建的映射关系A为：0°视角→（RGB：240，180，160）→195.4cd/m2→（RGB：108/212,84/156,74/144）；0°视角→（RGB：200，220，150）→150.3cd/m2→（RGB：150/100,90/150,80/120）。
当获取到10°视角（即为倾斜视角）的RGB基色的第二灰阶数据（RGB：150，120，190）的第二亮度数据为150.3cd/m2时，则就可以从映射关系A中找到与150.3cd/m2对应的是（RGB：150/100,90/150,80/120），因此（RGB：150/100,90/150,80/120）即为10°视角（即为倾斜视角）的RGB基色的第二灰阶数据（RGB：150，120，190）所对应的第二显示灰阶组合数据，因此也就创建了映射关系B：10°视角→（RGB：150，120，190）→150.3cd/m2--（RGB：150/100,90/150,80/120）。基于同样的方法，可得到其他视角下的RGB基色的第二灰阶数据所对应的第二显示灰阶组合数据。最后，当遍历完所有的倾斜视角（即0-90°的视角）后，即可得到所有视角下的第二显示灰阶组合数据，该第二显示灰阶组合数据即为所述目标显示灰阶数据，因此就创建了所述若干视角与显示灰阶数据之间的映射关系，即得到了所述灰阶数据查找表。这样，当所述显示设备获取到每一个像素点的视角后，就可以根据该灰阶数据查找表找到与该视角所对应的目标显示灰阶数据。
步骤S300、根据所述目标显示灰阶数据，对所述待显示图像进行显示。
由于本实施例获取到每一个像素点的视角所对应的所述目标显示灰阶数据后，因此显示设备在进行图像显示时，可基于目标显示灰阶数据进行显示，使得该待显示图像中每一个像素点都以最为合适的目标显示灰阶数据进行显示。此外，本实施例中的所述目标显示灰阶数据是由两个灰阶数据组合而成的，因此显示设备在进行显示时，可基于这两个灰阶数据进行分时显示，提高显示效果。
在一种实现方式中，如图4所示，所述步骤S300具体包括：
步骤S301、根据所述目标显示灰阶数据，得到所述目标显示灰阶数据中的R基色对应的灰阶组合数据、G基色对应的灰阶组合数据以及B基色对应的灰阶组合数据；
步骤S302、根据所述R基色对应的灰阶组合数据、所述G基色对应的灰阶组合数据以及所述B基色对应的灰阶组合数据，对所述待显示图像进行显示。
由于所述目标显示灰阶数据是由两个灰阶数据组合而成的，因此，在进行显示时，本实施例获取每一视角的目标显示灰阶数据，然后得到所述目标显示灰阶数据中的R基色对应的灰阶组合数据、G基色对应的灰阶组合数据以及B基色对应的灰阶组合数据；比如上述得到的R基色的灰阶组合数据为150/100，G基色的灰阶组合数据为90/150，B基色的灰阶组合数据为80/120），并将所述目标显示灰阶数据写入显示设备的芯片中。由于每个视角下的目标显示灰阶数据都是基于亮度数据相同或者比例相等的原则，根据垂直视角下的RGB基色的灰阶组合数据得到的，因此显示设备基于每一像素点的视角所对应的RGB基色的灰阶组合数据进行图像显示时，可以实现显示设备色度视角的改善，提高显示器不同视角下的观看体验，具有很好的市场应用前景。如图5所示，对显示设备所显示的图像进行色度视角测量，色度视角测量结果如图5所示，其中横坐标为显示设备旋转角度，纵坐标为色度偏差，从图5中可以看出，采用本实施例的显示方法之后，显示设备所显示的图像的色度视角有明显改善。
综上，本实施例首先获取待显示图像中每一个像素点所对应的视角。接着，本发明根据所述视角，获取与所述视角所对应的目标显示灰阶数据。由于本发明获取到了所述待显示图像中的每一个像素点对应的视角，以及每一个视角所对应的目标显示灰阶数据。这样当该待显示图像进行显示时，显示设备可以根据每一个像素点所对应的目标显示灰阶数据来对待显示图像进行显示，这样有助于保证该待显示图像中的每一个像素点都以最合适的灰阶数据进行显示，提高不同视角下的显示效果。
示例性装置
如图6中所示，本实施例还提供一种图像显示装置，该装置包括：视角获取模块10、灰阶数据获取模块20以及图像显示模块30。具体地，所述视角获取模块10，用于获取显示设备上的垂直视角位置，并根据所述垂直视角位置确定待显示图像中每一个像素点所对应的视角。所述灰阶数据获取模块20，用于根据所述视角，获取与所述视角所对应的目标显示灰阶数据。所述图像显示模块30，用于根据所述目标显示灰阶数据，对所述待显示图像进行显示。
在一种实现方式中，所述视角获取模块10包括：
