在图1所示的画面显示控制设备中，所述画面显示控制设备通过处理器1001调用存储器1005中存储的画面显示控制程序，并执行下述画面显示控制方法各个实施例中的操作。
基于上述硬件结构，提出本申请画面显示控制方法实施例。
参照图2，图2为本申请画面显示控制方法第一实施例的流程示意图，所述方法包括：
步骤S10，获取待显示的视频信号；
步骤S20，基于预设的倍频模式，对所述视频信号进行倍频操作，得到与所述视频信号对应的倍频信号；
步骤S30，基于预设的显示器参数gamma表格，确定所述倍频信号对应的灰度线性值；
步骤S40，基于所述灰度线性值和所述倍频模式，对所述视频信号的序列单元帧进行扩展，得到倍频序列单元帧，以进行画面显示。
本实施例中的画面显示控制方法，通过对获取到的视频信号进行倍频处理，并获取倍频处理后的倍频信号在显示器参数gamma表格中匹配对应的灰度线性值，该灰度线性值是根据倍频信号确定，进而依据该灰度线性值进行驱动显示，上述灰度线性值与进行倍频的视频信号的灰度线性值相一致，利用了倍频技术提高了显示屏的灰度值，进而优化显示设备的显示效果，提高在高刷新率和超高刷新率的显示帧率情况下的显示质量。
以下将对各个步骤进行详细说明：
步骤S10，获取待显示的视频信号；
在一具体实施例中，显示设备接收到信号源发送的待播放视频信号，根据该视频信号进行视频播放，在显示设备与信号源之间的数据传输的过程中，信号源发送的视频信号包括：电视信号、静止图像信号和可视电视图像信号。而视频信号的形成原理是通过利用红绿蓝，RGB三种颜色不同比例地进行混合表示不同色彩。不同的视频信号有不同的视频帧率，而相同的视频在不同视频帧率的表现下，观看者会有不同的视觉感受，上述视频帧率是用于测量视频显示帧数的量度，而该量度的测量单位为每秒显示帧数FPS或赫兹HZ。
由于人类眼睛的特殊生理结构，当人类所看画面的帧率高于16的时候，就会认为是连贯的，此现象称之为视觉停留，每秒的帧数(fps)或者说帧率表示图形处理器处理场时每秒钟能够更新的次数，高的帧率可以得到更流畅、更逼真的动画，显示设备的播放质量得到提升，随着显示技术的不断发展，显示屏帧刷新率已经从24帧，48帧，60帧提高到120帧，144帧，240帧等高刷新率，用户的观影体验不断得到提升。
步骤S20，基于预设的倍频模式，对所述视频信号进行倍频操作，得到与所述视频信号对应的倍频信号；
在一些具体的实施例中，因为高帧率的视频提升了影院中显示设备的显示质量，所以通过提高视频帧的刷新率来提升影院显示设备的显示效果。而上述提高视频帧的刷新率的方式是对视频信号进行倍频处理，得到高刷新率和超高刷新率的视频信号，该高刷新率和超高刷新率的视频信号相对于倍频处理前的视频信号，其帧率数值大小相差十分大，能够很直接地优化显示设备的显示效果，进而提升用户的观影体验。
具体地，预先设置好的倍频模式包括倍频系数值以及倍频方式，倍频系数是指原视频信号中的视频帧率要进行扩大的倍数，倍频方式是指视频进行倍频处理是手动设置或是自动设置。根据对获取到的视频信号进行倍频处理，得到对应的倍频信号。倍频信号中的倍频帧率的计算方式为：原视频帧率x 倍频系数值。
例如，获取到一段视频信号1，该视频信号1的常规帧刷新率为48帧，显示设备根据该48帧的视频信号1进行自动的二倍频处理，得到该48帧的视频信号1对应的96帧倍频帧率；获取到另一段视频信号2，该视频信号2的常规帧刷新率为24帧，操作员通过显示设备对该常规帧刷新率为24帧的视频信号2进行手动的三倍频处理，得到该24帧的视频信号2对应的72帧的倍频帧率。
步骤S30，基于预设的显示器参数gamma表格，确定所述倍频信号对应的灰度线性值；
在显示设备进行视频显示的过程中，显示器参数gamma值是指处理位图的一种特殊效果的调整参数，gamma值是指在图像处理工作进行时，视频亮度输入值和显示设备输显示的视频亮度输出值之间的关系，该项数值直接影响到图像、视频中间值的色调或是中间层次的灰度，通过调整gamma值可以改变图像中间色调灰阶的亮度值，以增加图像的中间层次，而不会对暗部和亮部的层次有太大的影响，用户可以调整显示器的gamma值，以模拟在比较显示器上与原稿上的图像的反差时的观视条件。
在一具体的实施例中，基于预先设置好的显示器参数gamma表格匹配倍频信号的灰度线性值，实现图像灰度的线性变化，图像灰度变换方法有很多，如线性变换、指数变换、幂变换、对数变换等，其中，线性变换就是利用直线方程实现灰度值变换。
例如，15比特显示设备视频处理单元预先设置好的显示器参数gamma表格为0-32767（2
15）的原始区间灰度线性范围，8帧的视频信号1进行自动的二倍频处理后，对应的显示器参数gamma表格同时从0-32767的原始区间灰度线性范围扩展到0-65535（2
16）的倍频区间灰度线性范围，需要进行具体解释说明的是，虽然倍频后gamma区间范围从0-32767扩展到0-65535，但是倍频后的序列单元帧的gamma区间范围还是所述15比特显示设备的物理gamma区间范围0-32767。既视频信号的单帧2倍频后扩展成了2个序列单元帧，在所述15比特显示设备上就是2个物理gamma区间范围0-32767的序列单元帧。
步骤S40，基于所述灰度线性值和所述倍频模式，对所述视频信号的序列单元帧进行扩展，得到倍频序列单元帧，以进行画面显示。
在一具体实施例中，根据倍频信号对应的灰度线性值，获取灰度线性值对应的显示功率，驱动显示设备进行显示。
参照图3，图3为本实施例中画面显示控制方法涉及到的视频信号处理模块，具体包括：获取3D视频信号单帧（左右帧）的视频信号获取模块，倍频设置模块，以及显示驱动模块，其中上述倍频区间灰度在0-65535，两块序列单元左帧原始区间灰度各包括一个0-32767的倍频区间灰度，另外，两块序列单元右帧原始区间灰度各包括一个0-32767的倍频区间灰度。显示驱动模块则包括序列单元左帧1、序列单元左帧2、序列单元右帧1和序列单元右帧2。
具体的，参照图4，图4为本实施例的具体流程图。获取普通帧率的视频信号；将上述普通帧率的视频信号自动或手动2倍频；显示设备视频处理单元将视频信号代码值转换成倍频区间灰度线性值；显示设备视频处理单元将倍频区间灰度线性值除以倍频数求商和模，商是倍频后序列单元帧的原始区间灰度线性值，模是需要加1灰度线性值的序列单元帧数量；显示设备视频处理单元按照计算出来序列单元帧灰度值驱动显示屏显示。
本实施例画面显示控制方法，通过对获取到的视频信号进行倍频处理，并获取倍频处理后的倍频信号在显示器参数gamma表格中匹配对应的灰度线性值，该灰度线性值是根据倍频信号确定，进而依据该灰度线性值进行驱动显示，上述灰度线性值与进行倍频的视频信号的灰度线性值相一致，利用了倍频技术提高了显示屏的灰度值，进而优化显示设备的显示效果，提高了显示设备进行显示时的灰阶值，优化显示设备的显示质量。
进一步地，基于本申请画面显示控制方法第一实施例，提出本申请画面显示控制方法第二实施例。
画面显示控制方法的第二实施例与画面显示控制方法的第一实施例的区别在于，本实施例是对步骤S20，基于预先设置好的倍频模式，对所述视频信号进行倍频操作，得到与所述视频信号对应的倍频信号的细化，参照图5，具体包括：
步骤S21，获取所述视频信号中的原始帧率和原始序列单元；
步骤S22，对所述原始帧率和原始序列单元进行基于所述倍频模式的倍频操作，得到对应的倍频帧率和倍频序列单元，所述倍频模式至少包含倍频参数值；
参照图6，步骤S22具体包括：
步骤S221，通过所述倍频模式中的预设操作方式，将所述原始帧率的信号源按照预设刷新速率进行增强，得到对应的倍频帧率，所述刷新速率与所述倍频模式中的倍频参数值一致；
步骤S222，通过所述倍频模式中的预设操作方式，将所述视频信号中的序列单元按照预设扩展倍数进行扩展，得到对应的倍频序列单元，所述预设扩展倍数与所述倍频模式中的倍频参数值一致。
在一具体实施例中，以15比特显示设备和48帧3D视频信号2倍频为例，所述显示设备接收所述视频信号根据预设的模式包括自动倍频或者手动倍频。所述显示设备视频处理单元原始gamma表为0-32767（2
15）的原始区间灰度线性范围，48帧3D视频信号2倍频后gamma表同时从0-32767的原始区间灰度线性范围扩展到0-65535（2
16）的倍频区间灰度线性范围。
此处要特别说明的是，虽然倍频后gamma区间范围从0-32767扩展到0-65535，但是倍频后的序列单元帧的gamma区间范围还是所述15比特显示设备的物理gamma区间范围既0-32767。既视频信号的单帧2倍频后扩展成了2个序列单元帧，在所述15比特显示设备上就是2个物理gamma区间范围0-32767的序列单元帧。
在本实施例中，通过对获取到的视频信号进行倍频处理，通过高刷新率以及超高帧刷新显示技术，减少播放过程中的画面闪烁，增加画面刷新率提高显示设备画面显示质量。
进一步地，基于本申请画面显示控制方法第一、第二实施例，提出本申请画面显示控制方法第三实施例。
画面显示控制方法的第三实施例与画面显示控制方法的第一、第二实施例的区别在于，本实施例是对步骤S30，基于预先设置好的显示器参数gamma表格，确定所述倍频信号对应的灰度线性值的细化，参照图7，具体包括：
步骤S31，获取与所述倍频信号对应的图像代码值；
步骤S32，基于所述gamma表格，将所述图像代码值转换为灰度线性值，所述图像代码值为非线性值。
在一具体实施例中，以16比特显示设备和24帧视频信号4倍频为例，上述显示设备视频处理单元将视频信号代码值转换成上述倍频区间灰度线性范围内的灰度线性值。例如：倍频区间灰度值为1027的线性值，1027除以4得到的商是256，模是3。即上述视频信号代码值对应的原始区间灰度线性范围的灰度线性值是256，3个序列单元帧需要加1。通过4倍频提高显示设备灰度的方法的1-4序列帧对应的灰度线性值是256，257，257，257，组成了倍频区间灰度值为1027的线性值。
进一步可以理解的是，预设的gamma表是按公式算出来的数值，可能是n的倍数也可能不是n的倍数，若是n的倍数那么余数就是0，若不是n的倍数那么余数就是1到n-1之间的一个值。同时，倍频区间灰度值分配给倍频后的序列单元帧对应的线性值可以是相同，也可以是不同，但不同仍在倍频区间范围内，且与视频信号对应的原始区间灰度线性值的差值在预设阈值（如1或2）内。
在本实施例中，通过将视频信号的倍频帧率对应的图像代码对照序列单元帧对应的gamma表格转化为线性值，使得显示设备能够对视频信号进行播放，在一定程度上实现了高刷新率和超高刷新率的画面显示。
进一步地，基于本申请画面显示控制方法第一、第二、第三实施例，提出本申请画面显示控制方法第四实施例。
画面显示控制方法的第四实施例与画面显示控制方法的第一、第二、第三实施例的区别在于，本实施例是对步骤S40，基于所述倍频信号对应的灰度线性值，确定对应的显示功率，基于所述显示功率对画面进行显示控制的细化，参照图8，具体包括：
步骤S41，获取所述倍频模式的倍频参数值；
步骤S42，基于所述灰度线性值以及所述倍频参数值，获得倍频序列单元帧和倍频区间灰度线性值。
参照图9，步骤S42具体包括：
步骤S421，将所述灰度线性值除以所述倍频参数值，计算得出所述灰度线性值除以所述倍频参数值的模和所述灰度线性值除以所述倍频参数值的商；
步骤S422，基于所述灰度线性值除以所述倍频参数值的模，确定序列单元帧的增加数量，并根据所述增加数量添加序列单元帧，确定进行显示的倍频序列单元帧；
步骤S423，基于所述灰度线性值除以所述倍频参数值的商，确定序列单元帧的原始区间灰度线性值，并根据所述原始区间灰度线性值确定进行显示的倍频区间灰度线性值。
在一具体实施例中，显示设备视频处理单元根据将所述倍频区间灰度线性范围除以所述倍频数并求模（余数），其中，经过运算得到的模的值就是就是需要增加1个灰度线性值的序列单元帧的数量，经过运算得到的商就是序列单元帧的原始区间灰度线性值。
具体地，以15比特显示设备和48帧视频信号2倍频为例，显示设备视频处理单元将视频信号代码值转换成倍频区间灰度线性范围内的灰度线性值。例如：倍频区间灰度值为1025的线性值，1025除以2得到的商是512，模是1，即上述视频信号代码值对应的原始区间灰度线性范围的灰度线性值是512，1个序列单元帧需要加1，上述通过2倍频提高显示设备灰度的方法的1-2序列单元帧对应的灰度线性值是512，513，组成了倍频区间灰度值为1025的线性值。
以16比特显示设备和24帧视频信号4倍频为例，显示设备视频处理单元将视频信号代码值转换成倍频区间灰度线性范围内的灰度线性值。例如：倍频区间灰度值为1027的线性值，1027除以4得到的商是256，模是3，即上述视频信号代码值对应的原始区间灰度线性范围的灰度线性值是256，3个序列单元帧需要加1，上述通过4倍频提高显示设备灰度的方法的1-4序列单元帧对应的灰度线性值是256，257，257，257，组成了倍频区间灰度值为1027的线性值。
步骤S43，基于所述倍频区间灰度线性值，确定所述倍频序列单元帧中进行显示的倍频区间灰度线性值，基于所述倍频区间灰度线性值对画面进行显示。
其中，所述基于所述倍频区间灰度线性值，确定所述倍频序列单元帧中进行显示的倍频区间灰度线性值，基于所述倍频区间灰度线性值对画面进行显示的步骤包括：
将所述倍频区间灰度线性值按照预设方式插入所述倍频序列单元帧中；
根据所述按照预设方式插入所述倍频序列单元帧中的倍频区间灰度线性值，确定所述倍频序列单元帧中进行显示的倍频区间灰度线性值，并基于所述倍频区间灰度线性值对画面进行显示控制。
在一具体实施例中，将倍频区间灰度线性值按预设方式插入到倍频序列单元帧中，如上述倍频序列单元帧对应的倍频区间灰度线性值是256，257，257，257，还可以是256，256，257，257。普通倍频技术的序列单元帧对应的gamma线性值是相同的固定值，而本方案申请实施例提出的画面控制方法经过倍频处理后的倍频序列单元帧对应的gamma线性值是可以不同的。
在本实施例中，通过对获取到的视频信号进行倍频处理，并获取倍频处理后的倍频信号在显示器参数gamma表格中匹配对应的灰度线性值，该灰度线性值是根据倍频信号确定，进而依据该灰度线性值进行驱动显示，上述灰度线性值与进行倍频的视频信号的灰度线性值相一致，利用了倍频技术提高了显示屏的灰度值，进而优化显示设备的显示效果，提高在高刷新率和超高刷新率的显示帧率情况下的显示质量。
