具体实施方式
以下结合附图对本实用新型的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本实用新型，并不用于限制本实用新型。
除非另作定义，本实用新型实施例使用的技术术语或者科学术语应当为本实用新型所属领域内具有一般技能的人士所理解的通常意义。本实用新型中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。
在显示设备的使用过程中，可以根据用户的需要，对显示图像进 行色域调整、GAMA调整等处理。以色域调整为例，终端设备可以采用3D LUT(Look Up Table，查找表格)技术对待调整图像的色域进行调整。具体地，根据待调整的图像中每个像素点的原始像素值，根据查找表格中的数据获得每个像素点的目标像素值，之后，根据每个像素点的目标像素值显示调整后的图像。
通常，色域调整参数(即，3D LUT中的数据)会在异构系统中传输。具体地，异构系统包括系统芯片和FPGA(Field-Programmable Gate Array，现场可编程门阵列)，其中，当系统芯片接收到用户的色域调整指令时，通过SPI(Serial Peripheral Interface，串行外设接口)向FPGA输出色域调整参数。而色域调整参数的数据量较大，参数的传输需要几帧的时间，且色域调整参数会进行动态更新，这样就可能导致同一帧图像中，部分区域的像素是根据原来的色域调整参数来进行像素值调整的，而另一部分区域的像素是根据更新的色域调整参数来进行像素值调整的，从而导致同一帧图像中不同区域的显示效果不一致。
图1为本公开的一些实施例中提供的视频数据处理装置的示意图，可选地，该视频数据处理装置100可以集成在FPGA中。如图1所示，该视频数据处理装置100包括：第一获取模块110、第二获取模块120、存储模块130和处理模块140。
其中，第一获取模块110配置为，响应于接收到的画质调整参数，判断所述画质调整参数是否满足预设条件，当所述画质调整参数满足预设条件时，将画质调整参数发送至存储模块130。
其中，画质调整参数可以由系统芯片发送给视频处理装置。例如，系统芯片在接收到用户所输入的画质调整指令时，生成的画质调整参数。画质调整指令可以为色域调整指令、Gama调整指令等。画质调整参数可以为：与Gama调整指令所对应的参数、与色域调整指令所对应的参数。以色域调整指令为例，该色域调整指令可以进一步包括： 将画面色域调整为第一色域的第一色域调整指令、将画面色域调整为第二色域的第二色域调整指令、将画面色域调整为第三色域的第三色域调整指令等。对于不同的色域调整指令，系统芯片所输出的色域调整参数也可以不同。
其中，第一获取模块110可以通过SPI接口接收系统芯片所发送的画质调整参数。SPI接口可以在第一时钟域(即SPI时钟域)下传输画质调整参数。其中，第一时钟域用于产生第一参考信号，该第一参考信号为时钟信号；SPI接口响应于第一参考信号的上升沿(或者下降沿、或者高电平状态、或者低电平状态)来进行数据传输，因此，第一时钟域下的数据传输速率与第一参考信号的时钟频率相关。
存储模块130配置为存储画质调整参数，并响应于帧同步信号的控制，将画质调整参数发送至处理模块140。其中，帧同步信号可以在本地时钟域下产生，帧同步信号的周期即为视频中的每帧图像的显示周期。另外，“响应于帧同步信号的控制，将画质调整参数发送至处理模块140”是指，从帧同步信号的有效状态的起始时刻开始，或者从帧同步信号处于有效状态的结束时刻开始，或者从帧同步信号的有效状态起始时刻与结束时刻之间的某一时刻开始，将画质调整参数发送至处理模块140，直至画质调整参数发送完毕。例如，有效状态为高电平状态。
第二获取模块120配置为获取原始视频数据，并响应于有效数据选通信号，将原始视频数据传输至处理模块140；其中，原始视频数据可以由视频源发送给视频数据处理装置100，有效数据选通信号的有效状态起始时刻与帧同步信号的有效状态起始时刻之间有预设时间间隔。该预设时间间隔即为每帧图像显示周期的帧消隐阶段。画质调整参数的传输时间段与原始视频数据的传输时间段无交叠。
在一些实施例中，画质调整参数可以在本地时钟域传输至处理模 块140，或者，画质调整参数可以在时钟频率更高的高速时钟域传输至处理模块140。
处理模块140配置为根据画质调整参数对原始视频数据进行数据处理，生成目标视频数据。该目标视频数据可以通过发送模块160发送至显示模组，以供显示模组根据目标视频数据进行显示。其中，发送模块160可以采用V-BY-ONE的标准进行数据发送。
需要说明的是，处理模块140接收到画质调整参数和原始视频数据的时间不同，当处理模块140接收到画质调整参数后，则可以对画质调整参数进行存储，并利用该画质调整参数对后续接收到的原始视频数据进行处理。在一些时间段，处理模块140可能未接收到画质调整参数，而仅接收到包括多帧图像数据的原始视频数据，这种情况下，处理模块140则可以利用当前存储的画质调整参数对原始视频数据进行处理。
在一些示例中，画质调整参数为利用3D-LUT来进行色域调整时所需要的参数，处理模块140具体可以根据画质调整参数对原始视频数据进行三维插值处理。
在本公开实施例中，系统芯片所输出的画质调整参数发送至视频数据处理装置100后，存储模块130先对接收到的画质调整参数进行缓存，之后，在帧同步信号的控制下，将画质调整参数发送至处理模块140；而第二获取模块120是在有效数据选通信号的控制下，将原始视频数据发送至处理模块140的，且画质调整参数的传输时间段与原始视频数据的传输时间段无交叠，从而使得处理模块140对同一帧视频图像进行处理时，是基于相同的画质调整参数来进行处理的，进而保证同一帧视频图像中不同区域的显示效果一致。
图2为本公开的另一些实施例中提供的视频数据处理装置的示意图，如图2所示，第一获取模块110包括：接收子模块112和校验子 模块113。
其中，接收子模块112配置为，接收系统芯片所发送的画质调整参数。
可选地，画质调整参数为串行数据，图3为画质调整参数的组成示意图，如图3所示，画质调整参数依次排列的：第一关键字HEAD、至少一个有效数据DATA0～DATAn、第二关键字END和校验值CRC。其中，校验值CRC由系统芯片所生成，并且，校验值CRC是对第一关键字HEAD、第二关键字END以及二者之间的有效数据DATA0～DATAn进行第一运算后得到的。
其中，接收子模块112具体可以包括：第一检测单元112a和第二检测单元112b，第一检测单元112a用于检测串行数据中的第一关键字，第二检测单元112b用于检测串行数据中的第二关键字，接收子模块112检测出第一关键字和第二关键字之后，可以进一步确定第一关键字与第二关键字之间的有效数据、以及第二关键字之后的校验码。
示例性地，为了区分出串行数据中的第一关键字、第二关键字和有效数据，可以将画质调整参数整体的位宽设置为32bit；将有效数据的位宽为30bit，并在有效数据的高两位补0，第一关键字的高两位和第二关键字的高两位分别选自“01”、“10”、“11”中的两者。例如，第一关键字为32位16进制数：FFFF_FFFF_FFFF_FFFF；第二关键字为32位16进制数：7FFF_FFFF_FFFF_FFFF。
示例性地，第一运算包括异或运算。
即，关键字CRC＝HEAD^DATA0^DATA1……^DATAn^END。
校验子模块113配置为，判断画质调整参数是否满足预设条件，当画质调整参数满足预设条件时，控制接收子模块112将画质调整参数输出至存储模块130；当画质调整参数不满足预设条件时，向系统芯片300发送数据请求信号，以使系统芯片300重新发送画质调整参 数。
可选地，校验子模块113具体被配置为，对接收到的画质调整参数中第一关键字、第二关键字、第一关键字与第二关键字之间的有效数据、以及校验值进行第二运算，并将该第二运算的结果与目标值对比，当第二运算的结果与目标值相等时，确定画质调整参数满足预设条件；否则，确定画质调整参数不满足预设条件，即，确定画质调整参数在传输过程中发生传输错误，此时，向系统芯片300发送数据请求信号，以请求系统芯片300重新发送画质调整数据。
其中，第二运算包括异或运算。第二运算的结果记作CRC’，则：
CRC’＝HEAD^DATA0^DATA1……^DATAn^END^CRC
当第一运算为异或运算时，则在画质调整参数传输准确的情况下，CRC’＝CRC^CRC＝0；因此，在一些实施例中，第一运算和第二运算均为异或运算时，目标值可以设置为0。
在一些实施例中，如图2所示，视频数据处理装置100还包括时序产生模块150，该时序产生模块150配置为，在第二时钟域(也即上文中的本地时钟域)下产生帧同步信号和有效数据选通信号。其中，帧同步信号的有效状态起始时刻与有效数据选通信号的有效状态起始时刻之间具有预设时间间隔，第二时钟域的时钟频率大于第一时钟域的时钟频率。例如，帧同步信号的有效状态起始时刻可以为帧同步信号的上升沿，帧同步信号的有效状态起始时刻与有效数据选通信号的有效状态起始时刻之间的预设时间间隔即为，一帧图像显示周期中的帧消隐阶段。其中，第二时钟域用于产生第二参考信号，该第二参考信号为时钟信号，时序产生模块150可以根据第二参考信号来生成帧同步信号和有效数据选通信号；发送模块160也可以根据第二参考信号来将目标视频数据发送给显示模组。例如，第二参考信号由本地晶振产生，例如，当本地晶振产生第m个第二参考信号的上升沿(或下 降沿)时，则帧同步信号处于上升沿；当本地晶振产生第n个第二参考信号的上升沿(或下降沿)时，则帧同步信号处于下降沿，m＞n，m、n均为整数。
其中，时序产生模块150输出的信号时序说明如下表1所示，其中，1VCLK表示第二时钟域中的一个时钟的时间；1Line表示显示一行的时间。
表1
时序参数名称 数值
HTT(行同步信号的周期) 2200(单位：1VCLK)
HAC(一行中的有效显示时间) 1920(单位：1VCLK)
HFP(行同步信号的前肩) 88(单位：1VCLK)
HSW(行同步信号的脉宽) 44(单位：1VCLK)
HBP(行同步信号的后肩) 148(单位：1VCLK)
VTT(帧同步信号的周期) 1125(单位：1Line)
VAC(显示周期中的有效显示时间) 1080(单位：1Line)
VFP(帧同步信号的前肩) 4(单位：1Line)
VSW(帧同步信号的宽度) 5(单位：1Line)
VBP(帧同步信号的后肩) 36(单位：1Line)
其中，存储模块130从帧同步信号的有效状态起始时刻开始，在第三时钟域下将画质调整参数发送至处理模块140，其中，第三时钟域用于产生第三参考信号，该第三参考信号为时钟信号；在第三时钟域下，存储模块130可以响应于第三参考信号的上升沿(或者下降沿、或者高电平状态、或者低电平状态)来进行数据传输，因此，第三时钟域下的数据传输速率与第三参考信号的时钟频率相关。第三时钟域的时钟频率大于第二时钟域的时钟频率。例如，第三时钟域的时钟频 率为第二时钟域的两倍。在第三时钟域下发送画质调整参数，从而保证画质调整参数在帧消隐阶段传输完毕。
其中，帧同步信号的有效状态起始时刻可以为上升沿时刻，而由于在实际的电路设计中，存储模块130难以直接检测到信号的边沿，因此，在实际应用中，可以在第三时钟域下根据帧同步信号生成脉冲信号，并在该脉冲信号的控制下发送画质调整参数。具体地，存储模块130包括：脉冲生成器132和第一存储器131，第一存储器131可以为RAM(random access memory，RAM)。脉冲生成器132配置为，在第三时钟域下生成脉冲信号，脉冲信号用于控制第一存储器131将画质调整参数输出至处理模块140。图4为本公开中的一些实施例中提供的一些信号的波形图，如图4所示，DE为有效数据选通信号。脉冲信号SOF的频率与帧同步信号VS的频率相同，脉冲信号SOF的上升沿时刻与帧同步信号VS的有效状态起始时刻相同；第三时钟域的时钟频率大于第二时钟域的时钟频率。
可选地，脉冲生成器132包括：第一生成单元和第二生成单元。其中，第一生成单元配置为，将帧同步信号VS延迟第一时间T1，以获得延迟信号VS_DLY(如图4所示)；其中，第一时间T1为第三时钟域的单时钟脉冲宽度。第二生成单元配置为，将延迟信号VS_DLY取反后，与帧同步信号VS进行与操作，得到脉冲信号SOF。
需要说明的是，帧同步信号VS、延迟信号VS_DLY均为在高电平状态和低电平状态之间切换的信号；将信号取反即为，将信号的高电平状态和低电平状态互换。将两个信号进行与操作得到脉冲信号即为，在两个信号均处于高电平状态的阶段，脉冲信号SOF处于高电平状态；而在其他阶段，脉冲信号SOF处于低电平状态。
在一些实施例中，第二获取模块120包括：接收器121、写内存控制器122和读内存控制器123。
其中，接收器121配置为在第四时钟域下接收原始视频数据，接收器121通过SDI(serial digital interface，串行数字)接口接收原始视频数据，并将接收到的串行数据转换为并行的视频数据。
其中，第四时钟域即为视频源的时钟域，第四时钟域用于产生第四参考信号，该第四参考信号为时钟信号，视频源响应于第四参考信号的上升沿(或者下降沿、或者高电平状态、或者低电平状态)来进行数据传输，因此，第四时钟域下的数据传输速率与第四参考信号的时钟频率相关。
写内存控制器122配置为，在第五时钟域下将原始视频数据写入第二存储器200。例如，第二存储器200为DDR(Double Data Rate，双倍速率)存储器，第五时钟域为DDR的读写时钟域。
读内存控制器123配置为，当有效数据选通信号达到有效状态时，在第五时钟域下读取存储器中的原始视频数据，并在第二时钟域下将原始视频数据发送至处理模块140。
其中，第五时钟域用于产生第五参考信号，该第五参考信号为时钟信号，写内存控制器122响应于第五参考信号的上升沿(或者下降沿、或者高电平状态、或者低电平状态)来将数据写入第二存储器；读内存控制器123响应于第五参考信号的上升沿(或者下降沿、或者高电平状态、或者低电平状态)来进行数据读取。因此，第五时钟域下的数据读取速率和数据写入速率与第五参考信号的时钟频率相关。
由于视频源的原始视频数据是在第四时钟域下传输给接收器121的，而处理模块140接收到的原始视频数据是在第二时钟域下传输的，因此，原始视频数据由视频源传输至处理模块140的过程中，需要进行跨时钟域的传输。而通过读内存控制器123、写内存控制器122的设置，可以实现数据的跨时钟域传输。另外，视频数据处理装置100还可以包括切换模块，该切换模块配置为，在接收器121未接收到原 始视频数据时，从第二存储器200或其他位置获取预先存储的预设图像数据，并输出至处理模块140，或直接通过发送模块160发送至显示模组，从而在视频数据处理装置100未接收到视频数据的情况下，显示模组仍能够显示预设的图像，该图像用于提示用户当前无视频数据输入。
图5为本公开的一些实施例中提供的视频数据处理方法示意图，该视频数据处理方法应用于上述视频数据处理装置100。结合图2和图5所示，该视频数据处理方法包括：
S10、第一获取模块110响应于接收到的画质调整参数，判断画质调整参数是否满足预设条件，当画质调整参数满足预设条件时，将画质调整参数发送至存储模块130。在一些实施例中，画质调整参数由系统芯片发送至第一获取模块110，第一获取模块110在第一时钟域下传输至第一获取模块110。例如，系统芯片通过SPI接口将画质调整参数发送至第一获取模块110，第一时钟域为SPI时钟域。
S20、存储模块130对画质调整参数进行缓存，并响应于帧同步信号的控制，将画质调整参数发送至处理模块140。
S30、第二获取模块120获取原始视频数据，并响应于有效数据选通信号，将原始视频数据传输至处理模块140；其中，画质调整参数的传输时间段与原始视频数据的传输时间段无交叠。在一些实施例中，帧同步信号和有效数据选通信号由时序产生模块150在第二时钟域下产生；其中，帧同步信号的有效状态起始时刻与有效数据选通信号的有效状态起始时刻之间具有预设时间间隔，第二时钟域的时钟频率大于第一时钟域的时钟频率。
S40、处理模块140根据画质调整参数对原始视频数据进行数据处理，生成目标视频数据。
需要说明的是，步骤S30的过程与步骤S10～S20的过程独立开。

S11、接收子模块112接收系统芯片所发送的画质调整参数。

其中，画质调整参数为串行数据，该串行数据包括依次排列的：第一关键字、至少一个有效数据、第二关键字和校验值；其中，校验值是对第一关键字、第二关键字以及二者之间的有效数据进行第一运算后得到的。这种情况下，步骤S12具体包括：校验子模块113对接收到的画质调整参数中第一关键字、第二关键字、第一关键字与第二关键字之间的有效数据、以及校验值进行第二运算，并将第二运算的结果与目标值对比，当第二运算的结果与目标值相等时，确定画质调整参数满足预设条件；否则，确定画质调整参数不满足预设条件。
其中，第一运算和第二运算均可以为异或运算。
其中，步骤S20具体包括：S20a、存储模块130从帧同步信号的有效状态起始时刻开始，在第三时钟域下将所述画质调整参数发送至处理模块140，其中，所述第三时钟域的时钟频率大于所述第二时钟域的时钟频率。
如上文所述，存储模块130具体包括：脉冲生成器132和第一存储器131。这种情况下，步骤S20a具体包括：第一存储器131存储画质调整参数；脉冲生成器132在第三时钟域下生成脉冲信号，脉冲信号用于控制第一存储器131将画质调整参数输出至处理模块140；其中，脉冲信号的频率与帧同步信号的频率相同，脉冲信号的上升沿时刻与帧同步信号的有效状态起始时刻相同；第三时钟域的时钟频率大 于第二时钟域的时钟频率。
其中，脉冲生成器132在第三时钟域下生成脉冲信号，具体包括：脉冲生成器132将帧同步信号延迟第一时间，以获得延迟信号；并将延迟信号取反后，与帧同步信号进行与操作，得到所述脉冲信号；其中，第一时间为第三时钟域的单时钟脉冲宽度。
在一些实施例中，步骤S30具体包括：接收器121在第四时钟域下接收原始视频数据；写内存控制器122在第五时钟域下将原始视频数据写入第二存储器200；读内存控制器123在所述第五时钟域下读取所述存储器中的原始视频数据，并在第二时钟域下将原始视频数据发送至处理模块140。
利用视频数据处理装置100进行数据处理的过程参见上文描述，这里不再赘述。
图7为本公开的一些实施例中提供的显示系统的示意图，该显示系统可以为监视器系统、计算机、智能手机等终端设备。如图7所示，显示系统包括：显示模组400、系统芯片300和上述视频数据处理装置100。
其中，系统芯片300配置为，响应于画质调整指令，输出相应的画质调整参数。
显示模组400配置为，响应于视频数据处理装置100输出的目标视频数据进行显示。其中，显示模组400包括显示面板和驱动电路，驱动电路配置为根据目标视频数据为显示面板提供驱动信号，以控制显示面板进行显示。
图8为本公开的一些实施例中提供的显示系统的显示过程示意图，如图8所示，该显示过程包括：
当系统芯片300接收到画质调整指令时，进行步骤S1a：系统芯片300向视频数据处理装置100发送画质调整参数。
S1b、视频数据处理装置100的第一获取模块110接收到画质调整参数后，判断画质调整参数是否满足预设条件，若满足，则进行步骤S1c；否则，向系统芯片300发送数据请求指令，从而再次执行步骤S1a。
S1c、将画质调整参数输出至存储模块130，以使存储模块130对画质调整参数进行缓存。
S1d、当帧同步信号开始达到有效状态时，存储模块130将缓存的画质调整参数发送至处理模块140。
S1e、处理模块140根据接收到的画质调整参数对其内部原来存储的参数进行更新。
另外，视频源向视频数据处理装置100发送原始视频数据，从而使视频数据处理模块140执行步骤S2a至步骤S3。
S2a、视频数据处理模块140的写内存控制器122将接收到的原始视频数据向写入第二内存器。
S2b、视频数据处理模块140的读内存控制器123从第二内存器中读出原始视频数据。
S2c、读内存控制器123响应于有效数据选通信号，将原始视频数据发送至处理模块140。
S3、处理模块140当前存储的画质调整参数对原始视频数据进行处理，得到目标视频数据。
S4、显示模组根据目标视频数据进行显示。
其中，当系统芯片接收到画质调整指令时，则步骤S3中“当前存储的画质调整参数”即为系统芯片根据画质调整指令所发出的画质调整参数；当系统芯片未接收到画质调整指令时，则处理模块140保持其存储的画质调整参数不变，此时，视频源仍可以发送原始视频数据，此时，处理模块140可以根据未被更新的画质调整参数进行处理。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
