下面结合附图，通过具体地实施例及其应用场景对本申请实施例提供的笔迹的显示方法进行详细地说明。
请参见图1，本申请实施例提供一种笔迹的显示方法，该笔迹的显示方法应用于双系统电子设备的第一系统，如图1所示，方法包括如下步骤：
步骤101、在接收到在第二系统的显示界面中输入第一书写操作的情况下，获取第二系统的笔迹颜色信息，其中，笔迹颜色信息用于指示与第二系统对应的第一图层显示笔迹的第一颜色；
步骤102、获取双系统电子设备的显示屏的第一显示模式，其中，第一显示模式为N种预设显示模式中的显示模式，且不同预设显示模式具有不同的图像质量参数，N为大于1的整数；
步骤103、确定第一系统在第一显示模式下与颜色笔迹信息匹配的第一颜色值；
步骤104、在第二图层以第二颜色显示第一书写操作的第一笔迹，其 中，第二图层为与第一系统对应的图层，第二颜色为具有第一颜色值的颜色，第一笔迹与第二笔迹叠设，且第二笔迹为第二系统基于第一书写操作在第一图层显示的笔迹。
在本申请实施例中，在接收到在第二系统的显示界面中输入第一书写操作的过程中，第一系统获取第二系统的笔迹颜色信息，然后基于第二系统的笔迹颜色信息匹配第一系统在第一显示模式下与笔迹颜色信息所对应的颜色值，最终以匹配到的颜色值在与第一系统的对应图层上显示笔迹。如此，通过本申请实施例，可以避免在第一图层的笔迹和第二图层的笔迹出现颜色差异较大的情况，从而提升双系统电子设备显示在显示书写操作的笔迹的显示质量。
需要说明的是，上述双系统电子设备包括显示屏、第一系统第二系统，显示屏用于显示第一系统或者第二系统的显示界面，以及，接收用户输入的操作(如书写操作等)；第一系统和第二系统可以理解为分别设置有不同操作系统的设备或者装置，第一系统和第二系统均设置有处理器以及存储器以实现独立运行。上述第一系统和第二系统的操作系统可以是包括Windows系统或者Android系统。具体地，上述第一系统为设置Android系统的设备或者装置(后续简称“第一系统为Android系统”)且上述第二系统为设置Windows系统的设备或者装置(后续简称“第二系统为Windows系统”)。
其中，上述第一系统可以是上述双系统电子设备的主系统，且第二系统可以是双系统电子设备的辅系统，双系统电子设备的显示屏在显示第二系统的显示界面的情况下，实际上是第二系统的显示界面以视频流的形式在第一系统下进行显示，即双系统电子设备通过高清多媒体接口(High Definition Multimedia Interface，HDMI)将第二系统的显示界面编码后的帧数据并传输至第一系统，第一系统对接收到的帧数据进行解码后，将第二系统的显示界面在双系统电子设备的显示屏中进行显示。
另外，在第一系统下显示第二系统的显示界面的情况下，第一系统在第一显示界面中设置有第一图层和第二图层，第一图层用于显示第二系统的图像，而第二图层用于显示第一系统的图像，且第二图层可以是以透明 形式覆盖于第一图层上。
在上述步骤101中，在双系统电子设备的显示屏中显示有第二系统的显示界面的情况下，若双系统电子设备接收到用户在第二系统的显示界面中输入第一书写操作，则双系统电子设备的第二系统可以获取到用于指示其显示笔迹所采用的第一颜色的笔迹颜色信息，并将获取到的笔迹颜色信息发送给第一系统，第一系统可以获取到第二系统的笔迹颜色信息。
本申请实施例中，上述笔迹颜色信息可以是任何用于指示第二系统当前显示笔迹所采用的第一颜色的信息，具体地，该第一颜色信息可以包括第一颜色的名称和序号等中的至少一项。
其中，上述第一颜色可以是双系统电子设备在接收到上述第一书写操作之前，根据用户输入的颜色选择操作确定的颜色，且该颜色选择操作可以是在第二系统下的至少一种预设颜色中选取颜色的操作，或者，也可以是调节颜色值(如RGB)以生成新的颜色的操作。
另外，在第二系统获取到上述颜色笔迹信息之后，上述第二系统可以是通过开放式拔插电脑规范(Open Pluggable Specification，OPS)将上述笔迹颜色信息发送至上述第一系统。
在此，以第一系统为Android系统，第二系统为Windows系统为例，在双系统电子设备接收到在Windows系统的显示界面书写“一”(即第一书写操作)的操作的情况下，且Windows系统设置的笔迹显示颜色为红色(即第一颜色)，此时，Windows系统可以获取到笔迹颜色信息为“红色”，并将获取到的笔迹颜色信息通过OPS发送给Android系统。
在上述步骤102中，在第一系统获取到第二系统发送的笔迹颜色信息之后，第一系统可以获取到双系统电子设备的显示屏当前的第一显示模式。
其中，上述第一显示模式可以是预先设置的多种显示模式中的一种，且上述多种显示模式中，不同显示模式具有不同的图像质量参数，该图像质量参数可以包括对比度、亮度、饱和度以及色温等中的至少一项。
例如，双系统电子设备的显示屏中预设有标准模式、明亮模式、鲜艳模式以及护眼模式等显示模式，在显示屏当前的显示模式为明亮模式情况 下，上述第一系统可以将明亮模式作为上述第一显示模式。
在上述步骤103中，在获取到双系统电子设备显示屏当前的第一显示模式的情况下，双系统电子设备的第一系统可以根据上述颜色笔迹信息，得到在第一显示模式下与笔迹颜色信息相匹配的第一颜色值。
需要说明的是，由于在不同的显示模式下，人眼对于颜色的感知存在差异，即对于同一颜色值，在不同显示模式下会发生细微的色差，那么，用户在不同显示模式下所观察的同一颜色，实际在不同模式下所对应的颜色值不同。
例如，在标准显示模式中，红色所对应的颜色值是(255，0,0)，但是在明亮显示模式下，由于受到显示屏的亮度等因素影响，使用(255，0,0)显示的“红色”和标准显示模式下的存在差异，因此，在明亮显示模式下，要想显示一样的红色，那么对应的颜色值可能为(205，0,0)。
本申请实施例中，上述在第一显示模式下与上述颜色笔迹信息匹配的第一颜色值，可以是双系统电子设备的第一系统根据预设的规则或者方法实现。具体地，上述步骤103，可以包括：
在第一系统的N个颜色值关系表中，确定与第一显示模式对应的第一颜色值关系表，其中，N个颜色值关系表与N种预设显示模式一一对应，且每一颜色关系表包括至少一组颜色与颜色值的映射关系；
在第一颜色值关系表中，确定与笔迹颜色信息所指示的第一颜色存在映射关系的颜色值为第一颜色值。
这里，上述双系统电子设备的第一系统可以根据预设的显示模式与颜色值关系表的对应关系，以及颜色值关系表中颜色与颜色值的映射关系，确定上述第一颜色值，从而使确定上述第一颜色值的过程中运算复杂度降低，进而提升双系统电子设备的处理效率。
在本申请实施例中，双系统电子设备的显示屏预设的多种显示模式中，每一种显示模式都对应一个颜色值关系表，每一个颜色值关系表中包含至少一组颜色和与其颜色对应的颜色值，因此，通过当前显示模式下对应的颜色值关系表，则可以匹配出和第一书写操作的笔迹颜色信息中的颜色对应的颜色值，即第一颜色值。
例如，假设预设标准显示模式与颜色值关系表1对应，且颜色值关系表1包括红色和(255，0,0)的映射关系；以及，预设明亮显示模式与颜色值关系表2对应，且颜色关系表2包括红色和(205,0,0)的映射关系.那么，在上述笔迹颜色信息为“红色”且显示屏处于标准显示模式(即目标显示模式)的情况下，上述第一系统在确定颜色值关系表1(即第一颜色值关系表)中的颜色值(255，0,0)(即第一颜色值)与“红色”匹配；或者，在上述笔迹颜色信息为“红色”且显示屏处于明亮显示模式(即目标显示模式)的情况下，上述第一系统在确定颜色值关系表2(即第一颜色值关系表)中的颜色值(205，0,0)(即第一颜色值)与“红色”匹配。
另外，上述双系统电子设备可以根据用户在第二系统的书写操作习惯，第二系统预先将书写时常用的几种颜色在各个显示模式对应的颜色值关系表中建立档案，即添加颜色及颜色值的映射关系。例如，用户常用黑、白、红、黄、绿、蓝等颜色书写笔迹，则可以在预设的多个显示模式所对应的颜色值关系表中分别添加黑、白、红、黄、绿、蓝等颜色和所对应的颜色值。
需要说明的是，上述映射关系的建立可以是双系统电子设备根据用户的操作实现；或者，在上述步骤103之前，上述方法还可以包括；
在显示屏在第二显示模式下显示第二系统的显示界面的情况下，若接收到第二书写操作，则获取第一图层显示第二书写操作的笔迹的第二颜色值，其中，第二颜色笔迹为用于第二系统显示笔迹的第三颜色的颜色信息；
在第一系统中的第二颜色值关系表中，添加第三颜色与第二颜色值的映射关系，其中，第二颜色值关系表与第二显示模式对应。
这里，双系统电子设备可以在第二系统的显示界面历史进行第二书写操作的过程中，根据第二系统显示第二书写操作的笔迹所采用的第三颜色，以及第三颜色在第二显示模式下的颜色值，建立与第二显示模式对应的第二颜色值关系表，从而使构建颜色关系表的操作更便捷，且确定的与笔迹颜色信息匹配的颜色值更合适，进一步提升双系统电子设备显示笔迹 的显示质量。
例如，当前显示屏处于标准显示模式(即第二显示模式)的情况下，双系统电子设备的画布层接收到用户在Windows系统(即第二系统)的显示界面中使用黑色(即第二颜色)书写笔迹(即第二书写操作)时，若此时第二系统获取到书写笔迹的颜色黑色所对应的颜色值为(0,0,0)(即第二颜色值)，则在标准显示模式对应的颜色值关系表(即第二颜色值关系表)中添加黑色与(0,0,0)的映射关系；
或者，当前显示屏处于柔和显示模式(即第二显示模式)的情况下，双系统电子设备的画布层接收到用户在Windows系统(即第二系统)的显示界面中使用黑色(即第二颜色)书写笔迹(即第二书写操作)时，若此时第二系统获取到书写笔迹的颜色黑色所对应的颜色值为(10,10,10)(即第二颜色值)，则在柔和显示模式对应的颜色值关系表(即第二颜色值关系表)中添加黑色与(10,10,10)的映射关系，等等。
需要说明的是，上述第二系统获取到与各显示模式对应的颜色值关系表之后，可以通过OPS向第一系统发送指示信息，该指示信息可以携带有颜色值关系表以及用于指示各显示模式与颜色值关系表的对应关系的信息，以使第一系统获取到颜色值关系表以及用于指示各显示模式与颜色值关系表的对应关系的信息。
当然，上述确定第一系统在第一显示模式下与颜色笔迹信息匹配的第一颜色值，也可以是通过模型预测或者计算得到。具体地，上述步骤103，可以包括：
在第一系统中，将颜色笔迹信息输入至目标颜色值预测模型中，得到第一颜色值，其中，目标颜色值预测模型与第一显示模式关联。
这里，可以通过与第一显示模式关联的第一颜色值预测模型得到上述第一颜色值，从而使双系统电子设备确定过上述第一颜色值的方式更灵活多样。
需要说明的是，上述第一系统中可以针对不同的显示模式预设有不同的颜色值预测模型，且各颜色值预测模型可以是由以颜色信息作为输入且颜色值作为输出的计算公式组成；或者，各颜色值预测模型也可以是通过 大量的颜色与颜色值的标注数据，对深度学习模型进行训练得到的模型。
另外，在本申请实施例中，双系统电子设备的第二系统的显示界面以视频流的形式在第一系统下显示的情况下，第二系统向第一系统传输帧数据所采用的帧率对显示的笔迹颜色，即不同帧率下同一颜色的颜色值不同。因此，上述在第一系统中，将颜色笔迹信息所指示的第一颜色输入至目标颜色值预测模型中，得到第一颜色值，可以包括：
获取在第一系统下显示第二系统的显示界面的目标帧率；
在第一系统中，将目标帧率以及颜色笔迹信息输入至目标颜色值预测模型中，得到第一颜色值。
这里，双系统电子设备的第一系统在确定笔迹颜色信息对应的第一颜色值的过程中，将上述目标帧率以及颜色笔迹信息同时作为预测或者计算第一颜色值的指标，从而使确定的第一颜色值更准确，使得得出的第一颜色值所对应的颜色无限接近于第一颜色，因此，避免了在第一图层的笔迹和第二图层的笔迹显示颜色差异过大，进一步提升显示屏的显示质量。
在上述步骤104中，在确定与笔迹颜色信息相匹配的第一颜色值的情况下，在第一系统的第二图层以第一颜色值所对应的第二颜色显示第一书写操作的第一笔迹，在第二系统的第一图层以第一颜色显示和第一笔迹叠设的第二笔迹。
本申请实施例中，在双系统电子设备接收到第一书写操作过程中，第一系统的画布层可以是将第一书写操作的笔迹在其第二图层上进行显示，并将第一书写操作的笔迹发送至第二系统，以使第二系统在其第一图层上进行显示，且第二图层显示的第一笔迹覆盖第一图层上的第二笔迹。
其中，由于第二系统生成笔迹的速度通常比第一系统生成笔迹的速度慢，即第二系统在其对应的第一图层显示书写操作的笔迹存在一定延时，故在第二系统的第一图层显示的第二笔迹可以为第一笔迹的部分笔迹，当然，第二笔迹也可以为第一笔迹的全部笔迹。
用户使用红色书写笔迹“一”，匹配出在标准模式下红色所对应的第一颜色值为255，那么，在Android系统的图层(即第二图层)以255所对应的颜色(即第二颜色)来显示笔迹“一”，在Windows系统的图层(即 第一图层)以红色显示用户书写的笔迹的一部分的“一”或者完整的“一”(即第二笔迹)。
这里，上述双系统电子设备显示屏在不同的显示模式下，因为每一个显示模式的图像质量参数不同，在显示屏不同的显示模式下，相同的笔迹颜色显示也会存在差异。因此，在本申请实施例中，根据第一系统在当前显示模式下与颜色笔迹信息匹配的第一颜色值，来确定显示屏的笔迹显示颜色值，可以得到准确的显示屏的笔迹显示颜色，进而避免显示屏显示的笔迹出现颜色差异较大的情况。

这里，笔记的显示装置200可以通过在接收到在第二系统的显示界面中输入第一书写操作的过程中，获取第二系统的笔迹颜色信息，然后基于第二系统的笔迹颜色信息匹配第一系统在第一显示模式下与笔迹颜色信息所对应的颜色值，最终以匹配到的颜色值在与第一系统对应的图层上显示笔迹。如此，可以避免在第一图层的笔迹和第二图层的笔迹出现颜色差异较大的情况，从而提升双系统电子设备显示在显示书写操作的笔迹的显示质量。

颜色及颜色值映射关系添加单元，用于在第一系统中的第二颜色值关系表中，添加第二颜色与第二颜色值的映射关系，其中，第二颜色值关系表与第二显示模式对应。
