具体实施方式
为使本申请示例性实施例的目的、技术方案和优点更加清楚，下面将结合本申请示例性实施例中的附图，对本申请示例性实施例中的技术方案进行清楚、完整地描述，显然，所描述的示例性实施例仅是本申请一部分实施例，而不是全部的实施例。
需要说明的是，本申请实施例以双系统的显示设备为例进行描述，显然，本申请色域空间动态调整方法也可以在单系统环境下运行。因此，基于本申请色域空间动态调整方法，本领域技术人员在不付出创造性劳动的前提下，所能够想到应用在任何系统环境下的技术方案都属于本申请的保护范围。
为便于用户使用，显示设备上通常会设置各种外部装置接口，以便于连接 不同的外设设备或线缆以实现相应的功能。而在显示设备的接口上连接有高清晰度的摄像头时，如果显示设备的硬件系统没有接收源码的高像素摄像头的硬件接口，那么就会导致无法将摄像头接收到的数据呈现到显示设备的显示屏上。
并且，受制于硬件结构，传统显示设备的硬件系统仅支持一路硬解码资源，且通常最大仅能支持4K分辨率的视频解码，因此当要实现边观看网络电视边进行视频聊天时，为了不降低网络视频画面清晰度，就需要使用硬解码资源(通常是硬件系统中的GPU)对网络视频进行解码，而在此情况下，只能采取由硬件系统中的通用处理器(例如CPU)对视频进行软解码的方式处理视频聊天画面。
采用软解码处理视频聊天画面，会大大增加CPU的数据处理负担，当CPU的数据处理负担过重时，可能会出现画面卡顿或者不流畅的问题。进一步的，受制于CPU的数据处理能力，当采用CPU软解码处理视频聊天画面时，通常无法实现多路视频通话，当用户想要再同一聊天场景同时与多个其他用户进行视频聊天时，会出现接入受阻的情况。
基于上述各方面的考虑，为克服上述缺陷，本申请公开了一种双硬件系统架构，以实现多路视频聊天数据(至少一路本地视频)。

为了维护方便，A芯片和N芯片所对应的子系统中，安装的应用程序可能存在不同，例如，A芯片对应的子系统中可以侧重于通过应用程序提高显示设备 的扩展功能，诸如电视直播、视频网站客户端、即时通讯等；而N芯片对应的子系统可以侧重于对显示设备本身的调整，诸如智能亮度调节、智能色彩调节、画面增强等。
相对应地，A芯片可以连接扩展应用程序对应的硬件设备，例如，安装在A芯片对应子系统中名称为“照镜子”的应用程序，其目的是通过A芯片内置的摄像头采集图像信号，并实时显示在屏幕上，以达到照镜子的效果。根据摄像头的产业规格，其可支持的色域空间为一个固定的标准值，例如常用的摄像头支持色域空间为BT.709，但随着对于高清影像的显示需求，显示技术不断发展，其支持的色域空间一般会比摄像头高，例如4k电视的色域空间为BT.2020标准。如此，通过“照镜子”应用程序所提供的图像归属的色域空间是BT.709，而电视机的显示色域空间为BT.2020，即存在色域空间差异，很容易在使用“照镜子”应用程序时，造成颜色失真。
色域空间，也称色彩空间，是指显示介质如屏幕、数码输出设备及印刷复制设备所能表现的颜色范围，根据应用场景的不同，包括多个色域标准，例如ITU国际电信联盟为高清电视制定的BT.709、BT.2020等。由于高清电视显示技术的发展，电视的色域空间也趋向越来越大。
同时，不仅限于显示功能的智能电视也得到发展，智能电视可在电视机的基础上通过内置或外接传感器、控制装置等，获得附加功能。例如，通过在电视机中内置摄像头，以采集图像数据，配合电视机中的软件应用，将采集到的图像数据实时显示在电视机屏幕上，从而实现“照镜子”、“边看边聊”等功能。
然而，受限于内置或外接设备的硬件情况，内置或外接设备所对应的色域空间与电视机显示的色域空间可能存在不同。例如，内置摄像头的色域空间采 用的是BT.709标准，而电视机显示的色域空间大于BT.709标准。这样的色域差异会造成电视机显示内置或外接设备所提供的图像时，出现部分颜色失真。例如，用大于BT.709标准的电视机显示BT.709标准的图像时，红色部分的颜色失真严重。
由此可以看出，当内置或外接设备所对应图像内容的色域空间与电视机显示的色域空间不同时，可能导致显示效果出现颜色失真，影响用户的观影体验。
为了缓解颜色失真的问题，本申请提供一种显示设备及色域空间动态调整方法。参见图8，为本申请一种色域空间动态调整方法的流程示意图。由图8、可知，本申请提供的显示设备包括：摄像头、显示器以及控制器，其中，所述摄像头被配置为采集环境图像数据，显示器被配置为显示用户界面，控制器与显示器之间建立通信连接，被配置为执行呈现用户界面，以及，判断当前启动应用是否为摄像头相关应用。其中，显示器的默认显示色域空间为第一色域空间，所述摄像头相关应用所提供图像归属的色域空间为与第一色域空间不同的第二色域空间。若是，则将显示器的显示色域空间转换为第二色域空间。
相应地，本申请提供的色域空间动态调整方法包括以下步骤：
S11：获取当前启动应用信息。
本申请提供的技术方案中，可以通过预定义的进程实时监控应用程序的启动情况，以获取当前启动应用信息。本申请中当前应用启动信息可以通过包名信息进行表示。
例如，当任一应用程序启动时，通过获取其对应的包名信息，确定当前启动的应用程序。所述包名信息是根据显示设备的机型状态而预设的程序描述文件，可以为一段字符串，当对应的应用程序启动后，可以在系统内存中获取该 字符串。示例地，“照镜子”程序对应的包名信息可以为“com.hisense.tv.mirror”。
对于双系统的显示设备，其应用程序对应的包名信息可以存储在由第二硬件系统创建或存储的包名集合文件中。包名集合文件可以由第二硬件系统中的一个分区进行存储。例如，在N芯片对应的子系统中，预先划分一个名为tvconfig的分区，并在tvconfig分区中按照显示设备的机型存储一个XML文件，作为包名集合文件。该XML文件中存储有各应用程序对应的包名信息。包名集合文件可以用来动态配置，以通知A芯片，诸如“照镜子”的应用程序启动后，需要调整色域空间。
在本申请的部分实施例中，如图9所示，获取当前启动的应用程序包名信息的步骤，还包括以下步骤：
S101：第一硬件系统从第二硬件系统中获取包名集合文件；所述包名集合文件包括所有应用程序的包名信息以及所提供图像归属的色域空间；
S102：所述第一硬件系统加载所述包名集合文件，以根据所述包名集合文件，监听各应用程序的启动状态；
S103：所述第一硬件系统从所述包名集合文件中提取当前启动的应用程序包名信息。
本实施例中，A芯片对应的第一硬件系统可以从N芯片对应的第二硬件系统分区中提取包名集合文件，即提取XML文件。为了便于后续确定应用程序所提供图像归属的色域空间，在本实施例中，可以在包名集合文件中进一步预设包名信息以及所提供图像归属的色域空间。例如，针对“照镜子”应用，其对应在包名集合文件的信息中，可以包括“com.hisense.tv.mirror”和“BT.709”。
可选的，在A卡芯片对应的第一硬件系统内，可以配置一个Activity Monitor  Service模块。该模块在系统开机后，启动运行，通过RPC通信接口读取第二硬件系统中的包名集合文件，以确定需要设置色域空间的应用包名信息。获取到包名集合文件后，可以根据包名集合文件监听各应用程序的启动状态。当任一应用程序启动后，Activity Monitor Service模块可以根据启动的应用程序，在包名集合文件中提取应用程序对应的包名信息。进一步地，还可以在包名集合文件中提取应用程序所提供图像归属的色域空间对应的信息。
为了实现上述功能，可以在N芯片对应的第二硬件系统内置Message Trans Service模块，在开机启动后从数据分离读取“照镜子”应用的包名信息，并保存在内存中，以供A卡对应的第一硬件系统进行后续判断。
由于N芯片是侧重于系统控制本身功能的芯片，因此N芯片所对应的第二硬件系统可以是基础系统。进一步地，可以通过云服务器与N芯片对应的第二硬件系统进行通信，以实现显示设备的云服务。相应的，第一硬件系统通过第二硬件系统获取包名集合文件的方式，可以实现N卡数据的分离功能，从而动态配置哪些应用程序需要调整色域空间，并且在应用程序有更新时，通过N卡系统配置云服务，以对包名集合文件进行实时更新，便于后续的应用拓展。另外，上述包名集合文件的管理方式还可以实现，根据从N芯片对应的第二硬件系统获取的包名进行适配，对应用程序进行统一设置，无需对每个应用程序进行设置，有利于管控。
因此，如图10所示，在本申请的部分实施例中，所述方法还包括以下步骤：
S104：第二硬件系统根据当前安装的应用程序创建包名集合文件，或者，从云端服务器获取包名集合文件；
S105：存储所述包名集合文件；
S106：通过通信接口，将所述包名集合文件发送至所述第一硬件系统。
本实施例中，所述包名集合文件可以由第二硬件系统，根据当前安装的应用程序自动创建，也可以通过云端服务器进行统一配置。其中，云端服务器可以由生产商统一进行包名集合文件的管理，以统一发布更新服务。在创建或获取包名集合文件后，第二硬件系统可以将包名集合文件进行存储，以在每次开机启动后，通过通信接口，将文件发送给第一硬件系统，供A芯片对应的第一硬件系统进行判断。
可见，本实施例中，包名集合文件由N卡对应的第二硬件系统完成，可以通过第二硬件系统直接从云服务器获取更新数据，以不断完善包名集合文件。同时，可以减少第一硬件系统内存空间的占用，使第一硬件系统能够更流畅的运行应用程序。
在本申请的部分实施例中，如图11所示，第二硬件系统可以通过以下步骤对包名集合文件进行更新，以实现应用拓展：
S1041：第二硬件系统从云端服务器获取包名更新数据；
S1042：根据所述更新数据，修改存储的所述包名集合文件；
S1043：通过通信接口，将修改后的包名集合文件发送至所述第一硬件系统。
本实施例中，N芯片对应的第二硬件系统可以通过从云端服务器下载的方式，获取包名集合文件的更新数据，具体的更新方式，可以是由第二硬件系统定期查询下载，也可以是由云端服务器统一实时发布。在获取到更新数据后，第二硬件系统可以根据获取的更新数据，对存储的包名集合文件进行修改，替换包名集合文件中包名信息和应用程序所提供图像归属的色域空间数据。并且，在替换数据后，可以在开机启动后，通过通信接口将修改后的包名集合文件发送 至第一硬件系统，以使第一硬件系统按照修改后的包名集合文件进行后续判断，确定应用程序所提供图像归属的色域空间。
S12：判断当前启动应用是否为摄像头相关应用，其中，所述摄像头相关应用所提供图像归属的色域空间为与默认显示色域空间不同的第二色域空间。
本申请提供的技术方案中，当前启动应用所提供图像归属的色域空间为，与默认显示色域空间相同的第一色域空间，或与默认显示色域空间不同的第二色域空间。其中，第一色域空间为默认显示色域空间，归属第一色域空间的应用为无需转换色域空间的应用。例如“电影”应用、“电视直播”应用等，为了突出画面色彩的层次感，需要通过广色域来显示，因此电影应用所提供图像归属的色域空间应当与显示色域空间相同，即为显示设备所支持的最大色域空间。因此，根据“电影”应用的包名信息“com.hisense.tv.movie”，可以确定“电影”应用所提供图像归属的色域空间为第一色域空间。
第二色域空间是指代与默认显示色域空间不同的色域空间，需要进行色域转换才能获得更好的显示效果，归属第二色域空间的应用也可以有多种。例如“照镜子”应用，受限于摄像头硬件所能够提供的最大色域空间，“照镜子”应用所支持的最大色域空间可能无法达到显示色域空间的范围，即“照镜子”应用所提供图像归属的色域空间与显示色域空间不同，是内置或外接设备所能够达到的最大色域空间。因此，根据“照镜子”应用的包名信息“com.hisense.tv.mirror”，可以确定“照镜子”应用所提供图像归属的色域空间为第二色域空间。
需要说明的是，在本申请提供的技术方案中，显示色域空间可以为当前显示设备所支持的色域空间，所述第一色域空间和第二色域空间可以是预先对每 个应用进行的统一分类。如果应用程序所提供图像归属的色域空间与显示色域空间相同，则对应应用属于第一色域空间；如果应用程序所提供图像归属的色域空间与显示色域空间不同，则对应应用属于第二色域空间。例如，显示设备的最大色域空间标准为BT.2020，则“照镜子”等非BT.2020色域空间的应用归属于第二色域空间的分类；而“电影”等BT.2020标准色域空间的应用，或者其他对色域空间没有限制的应用归属于第一色域空间的分类。
在本申请提供的技术方案中，所述第一色域空间和第二色域空间还可以是，根据应用所提供图像支持的色域空间，与当前显示色域空间之间进行对比而产生的两个相对的状态分类，即同一个应用在不同的使用阶段所提供的图像，可以归属于不同的色域空间。例如，当前启动的应用程序为“照镜子”，其所提供图像支持的最大色域空间为BT.709，如果当前显示色域空间也是BT.709，则此时“照镜子”应用所提供图像归属的色域空间为第一色域空间。又例如，当前启动的应用程序还是“照镜子”，其所提供图像支持的最大色域空间为BT.709，而当前显示色域空间是BT.2020，则此时“照镜子”应用所提供图像归属的色域空间为第二色域空间。
本申请提供的技术方案中，如果显示设备中包括前述双系统，可以通过A芯片对应的第一系统确定应用程序所提供图像归属的色域空间。具体判断方法可以为，第一硬件系统在监听到当前启动的应用程序后，获取应用程序对应的包名信息。并且根据包名信息，在包名集合文件中匹配当前应用所支持的色域空间，再通过对比应用程序支持的色域空间，与当前显示色域空间，确定当前应用所提供图像归属的色域空间是第一色域空间还是第二色域空间。
本申请的部分实施例中，如图12所示，判断当前启动应用是否为摄像头相 关应用的步骤，包括：
S201：获取当前启动应用的包名信息；
S202：根据所述包名信息，匹配预设摄像头相关应用包名信息；
S203：如果所述包名信息与预设摄像头相关应用包名信息相同，确定当前应用程序为摄像头相关应用。
在本实施例中，可以根据当前启动应用的包名信息与预设的摄像头相关应用包名信息进行匹配，并且根据匹配结果确定当前应用是否为摄像头相关应用。例如，当前启动应用的包名信息为“com.hisense.tv.mirror”，相应的与预设摄像头相关应用的包名信息相同，则确定当前启动应用为摄像头相关应用。
S13：若是，则将所述显示器的显示色域空间转换为所述第二色域空间。
本申请提供的技术方案中，为了缓解色差，可以通过软件方式将显示器的显示色域空间转化为第二色域空间。例如，当前启动的应用程序为“照镜子”，应用程序支持的最大色域空间为BT.709，当前显示色域空间为BT.2020，确定当前应用程序所提供图像归属色域空间为第二色域空间。此时，通过广色域的显示设备显示“照镜子”应用所提供图像，容易出现色彩失真。因此，可以通过调整显示设备的显示色域空间，将显示色域空间设置为第二色域空间，即，将显示设备当前显示色域空间调整为BT.709，以缓解应用程序与显示设备对应的色域空间差异，缓解色彩失真问题。
本申请提供的技术方案中，如果显示设备为上述双系统设备，由于N芯片对应的第二硬件系统主要用于对系统基础功能进行控制和调整，因此，可以通过N芯片对应的第二硬件系统将显示色域空间调整为第二色域空间。可选的，可以通过在第二硬件系统中定义一个进程，例如hstvos进程，这一进程在系统 开机后，可以保持后台运行，当A芯片对应的第一硬件系统，判断当前启动的应用程序需要调整色域空间时，可以通过RPC通信接口传递设置信号，以激活hstvos进程运行设置，从而将显示色域空间调整为第二色域空间。
需要说明的是，本申请以“照镜子”应用启动过程为例，描述上述色域空间的动态调整方法。在实际应用中，可以根据具体的应用环境完成对显示色域空间进行的不同调整。例如，在显示设备从“照镜子”应用切换至“电影”应用时，由于为适应“照镜子”，显示色域空间已被调整为BT.709，而“电影”应用需要广色域提高显示质量，因此，还需要将显示色域空间还原回BT.2020标准的色域空间。即在本申请的部分实施例中，所述方法还包括：第二硬件系统通过设置接口，将显示色域空间设置为所述第二色域空间；或者，第二硬件系统通过还原接口，将显示色域空间设置为所述第一色域空间。
另外，对于本申请提供的显示设备，由于摄像头相关应用程序数量，占所有应用程序数量的比例较小，相应应用使用的频率也不高。在多数情况下，显示设备的显示色域空间不会进行调整。因此，在运行需要调整色域空间的应用程序后，还可以自动将显示色域空间调节回第一色域空间，使得显示色域空间为显示设备所支持的最大色域空间。
即在本申请的部分实施例中，如图13所示，所述方法还包括以下步骤：
S401：接收所述摄像头相关应用的停止指令；
S402：若已接收到所述停止指令，则将显示色域空间还原为所述第一色域空间。
其中，所述停止指令为在退出所述摄像头相关应用程序时自动生成的指令。例如，在运行完“照镜子”应用后，用户退出“照镜子”应用。此时，第一硬 件系统可以通过检测内存中的应用运行状态，确定“照镜子”应用在退出时产生的停止指令。所述停止指令可以在判断内存中的应用包名信息不再处于激活状态而生成；也可以通过用户控制器的操作状态生成，如检测到电视机遥控器的退出键被按下时生成停止指令。根据接收停止指令的情况，可以判断是否已退出应用程序，如果已退出应用，可以将显示色域空间还原回默认显示色域空间。
针对应用程序而对显示色域空间进行调整包括设置和还原，而设置和还原过程可以发生在应用的打开、切换和关闭应用时。其中，切换应用程序可能存在多种情况，针对不同的情况，可以进行相应的控制。例如，当前显示设备是从“照镜子”应用切换到“电影”应用，由于两者所提供的图像的色域空间是不同的，因此需要第二硬件系统将显示色域空间进行调整，即调整为“电影”应用对应的BT.2020；如果当前显示设备上的应用切换，是从“电影”应用切换到“照镜子”应用，则需要第二硬件系统将显示色域空间从BT.2020调整到BT.709；如果当前显示设备上的应用切换，是从“电影”应用切换到“电视直播”应用，由于两者所提供图像归属的色域空间是相同的，因此，无需对显示色域空间进行调整，以提高应用切换的速度。
由以上技术方案可知，本申请提供一种显示设备及色域空间动态调整方法，通过实时监听显示设备中的应用程序启动状态，判断当前启动应用是否为摄像头相关应用，若是则将显示器的显示色域空间转换为与摄像头相关应用所提供的第二色域空间，或者调整摄像头采集的环境图像数据进行色域空间转换。所述方法可以根据启动的应用程序动态调整显示色域空间，改善显示色域空间与应用程序对应的色域空间之间的差异，缓解颜色失真的问题。
在本申请的另一个实施例中，还可以将摄像头采集的环境图像数据进行色域空间转换，以使环境图像数据符合显示器的色域空间。因此，在本申请中，还可以按照如下步骤进行动态调整：
S21：获取当前启动应用信息以及摄像头采集的环境图像数据；
S22：判断当前启动应用是否为摄像头相关应用，其中，所述摄像头相关应用所提供图像归属的色域空间为与默认显示色域空间不同的第二色域空间；
S23：若是，则将所述摄像头采集的环境图像数据进行色域空间转换。
对应于上述色域空间的动态调整方法，本申请实施例还提供一种显示设备，用于实现上述调整方法，显示设备包括：显示器、摄像头以及控制器，其中，控制器与显示器建立通信连接，该显示器被配置为显示用户界面及环境图像数据，所述显示器默认显示色域空间为第一色域空间；该摄像头被配置为采集环境图像数据，所述摄像头所提供图像归属的色域空间为与所述第一色域空间不同的第二色域空间；控制器被配置为执行呈现用户界面，以及，判断当前启动应用是否为摄像头相关应用；若是，则将所述摄像头采集的环境图像数据进行色域空间转换。
本实施例与上述实施例的区别在于，本实施例是通过将所述摄像头采集的环境图像数据进行色域空间转换的方式，实现动态调整。例如根据默认显示色域空间，将图像中的色彩进行变换，从而消除环境图像数据与默认显示色域空间之间的差异，缓解色差。

显示设备还可以内置控制装置和通信装置，例如红外遥控接收装置和网络接口，通过控制装置和通信装置可以实现对显示装置画面展示功能的控制，还可以对存储器中安装的应用进行更新或卸载，以满足不同的使用需求。
