参见图4，在一些实施例中，将系统分为四层，从上至下分别为应用程序(Applications)层(简称“应用层”)，应用程序框架(Application Framework)层(简称“框架层”)，安卓运行时(Android runtime)和系统库层(简称“系统运行库层”)，以及内核层。
框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。应用程序框架层相当于一个处理中心，这个中心决定让应用层中的应用程序做出动作。应用程序通过API接口，可在执行中访问系统中的资源和取得系统的服务。
如图4所示，本申请实施例中应用程序框架层包括管理器(Managers)，内容提供者(Content Provider)等，其中管理器包括以下模块中的至少一个：活动管理器(Activity Manager)用与和系统中正在运行的所有活动进行交互；位置管理器(Location Manager)用于给系统服务或应用提供了系统位置服务的访问；文件包管理器(Package Manager)用于检索当前安装在设备上的应用程序包相关的各种信息；通知管理器(Notification Manager)用于控制通知消息的显示和清除；窗口管理器(Window Manager)用于管理用户界面上的括图标、窗口、工具栏、壁纸和桌面部件。

在一些实施例中，如图5中所示，应用程序层包含至少一个应用程序可以在显示器中显示对应的图标控件，如：直播电视应用程序图标控件、视频点播应用程序图标控件、媒体中心应用程序图标控件、应用程序中心图标控件、游戏应用图标控件等。
在一些实施例中，直播电视应用程序，可以通过不同的信号源提供直播电视。例如，直播电视应用程可以使用来自有线电视、无线广播、卫星服务或其他类型的直播电视服务的输入提供电视信号。以及，直播电视应用程序可在显示设备200上显示直播电视信号的视频。

在一些实施例中，应用程序中心，可以提供储存各种应用程序。应用程序可以是一种游戏、应用程序，或某些和计算机系统或其他设备相关但可以在智能电视中运行的其他应用程序。应用程序中心可从不同来源获得这些应用程序，将它们储存在本地储存器中，然后在显示设备200上可运行。
目前，显示设备200通常使用ACR(Auto Content Recognition，自动内容识别)功能采集显示的内容进行内容识别，最终再将内容识别结果用于显示设备200的AQ(Audio Quality，声音质量)和PQ(Picture Quality，图像质量)的增强，以及内容推荐等，以提升用户使用显示设备200的体验感。
但是，ACR功能也存在一些缺点，例如其内容识别依赖于第三方服务商，再例如ACR功能只在特定的国家支持，其使用具有局限性等。为了避免ACR功能的前述缺点引发的问题，当前也有一些显示设备200使用AIPQ(Artificial Intelligence Picture Quality，智能图像模式切换)功能。AIPQ功能是利用机器学习模型识别显示设备200当前播放内容的场景，并根据识别到的场景自动应用具有场景针对性的PQ参数，给用户提供更佳的观看体验。这种功能不受第三方服务商的限制也可以在任何地区使用，使用范围更广。
但是，AIPQ功能的使用过程中如果存在无法识别的场景，那么显示设备200将会使用预存的默认PQ参数进行图像显示，然而根据默认PQ参数显示的图像很多时候不能满足用户观看显示设备200的体验要求。因此，当前显示设备200使用AIPQ功能也存在着影响用户体验感的问题。
基于以上问题，本申请实施例提供了一种图像显示方法及显示设备，将智能图像模式切换AIPQ功能与自动内容识别ACR功能结合，当智能图像模式切换AIPQ功能无法识别场景时，本申请的方案无需使用默认图像参数，也可以实现高质量图像的显示，保证目标图像能够满足用户观看显示设备200的体验要求，同时也能避免AIPQ功能和ACR功能同时使用时，图像质量参数的调整过程出现的冲突。
本申请实施例提供的显示设备200至少包括显示器275和控制器250，其中显示器275用于显示用户需要观看的目标图像，控制器250用于控制显示设备200响应用户输入的控制指令、设置图像质量参数以及根据图像质量参数显示目标图像等等。
当用户想要观看某个图像时，会向显示设备200输入指令，用以调整显示设备200当前显示的内容，用户可以通过按下遥控器上的按键向显示设备200输入指令，也可以通过向显示设备200说出想选择的内容进而向显示设备200输入指令。
显示设备200接收到用户的指令后，会选择相应的信号源通道播放播放用户想要观看的目标图像。为了保证目标图像的质量可以满足用户的要求，如图6所示，控制器250需要获取目标图像，然后利用智能图像模式切换AIPQ功能和/或自动内容识别ACR功能设置目标图像对应的目标图像质量参数，最后再控制显示器275根据目标图像质量参数显示上述目标图像。通常，AIPQ功能和ACR功能均能针对识别到的内容匹配或者计算出一系列图像质量参数，这种图像质量参数相比于显示设备200中默认的图像质量参数来说，能使目标图像显示得更加清晰并且图像的RGB亮度等更加优化，目标图像更加真实。
其中，AIPQ功能可以利用机器学习模型识别出目标图像的场景，并且根据场景匹配到具有场景针对性的图像质量参数。在实际应用时，针对于AIPQ功能能识别到的不同场景都会预先对应设置一些图像质量参数。例如，利用AIPQ功能可以识别出的场景包括草地、天空、人脸、建筑等，那么针对于草地、天空、人脸和建筑会分别预先配置一些较优的图像质量参数，如果识别目标图像的场景为草地，那么AIPQ功能就可以匹配到草地场景对应的图像质量参数，进而调整草地场景图像的清晰度、对比度、图像RGB亮度、色度等，使得目标图像中的草地及其他物体呈现得更加逼真。
ACR功能可以利用计算机算法直接识别多媒体内容，进而根据识别出的内容计算出该内容对应的一系列参数。本申请实施例中的ACR功能主要用于识别目标图像的内容，进而根据识别出的内容计算并设置一些图像质量参数，例如，利用ACR功能识别出目标图像中有人脸、有草地等，那么ACR功能可以考虑到人脸和草地的颜色特征，进而计算出符合人脸和草地特点的图像质量参数，以调整目标图像中人脸和草地显示的清晰度、对比度、图像RGB亮度和色度等，使得人脸和草地等事物呈现得更加逼真。
在一些实施例中，如图7所示，控制器250在获取目标图像之后，还需要判断目标图像所在的目标信号源是否存在于信号源白名单中，进而确定显示设备200当前是否可以利用AIPQ功能来设置目标图像参数。AIPQ功能的使用，需要截取显示设备200当前显示的图像，但是例如一些Netflix、Amazon、Youtube等第三方应用，会基于CSP(Content-Security-Policy，内容安全策略)的内容不允许对视频进行截屏，所以显示设备200对有版权保护的内容不能进行AIPQ操作，如果强制进行AIPQ操作会引起合作方的投诉，引起法务问题。基于这种情况，可以将不受CSP要求的信号源加入到信号源白名单中，通过判断信号源是否存在于白名单中，来判断该信号源所提 供的内容是否允许进行AIPQ操作。在目标信号源存在于信号源白名单中的情况下，可以利用AIPQ功能和/或ACR功能设置目标图像质量参数，而后控制器250控制显示器275根据目标图像质量参数显示目标图像；如果目标信号源不存在于信号源白名单，则目标信号源无法支持AIPQ操作，控制器250只能利用ACR功能设置目标图像质量参数，而后控制器250控制显示器275根据目标图像质量参数显示目标图像。
在一些实施例中，如图8所示，如果目标信号源存在于信号源白名单中，则控制器250还要继续判断利用AIPQ功能能否识别到目标图像的场景。因为，针对于AIPQ功能训练的机器学习模型虽然基于海量的样本图像场景，但是并不能保证一定涵盖了所有的场景，进而AIPQ功能能够识别出的场景也是有限的。例如机器学习模型中如果只训练出草地、天空、人脸、建筑四种场景，那么对于除这四种之外的场景AIPQ是识别不到的。如果利用AIPQ功能可以识别到目标图像的场景，那么控制器250才可以使用AIPQ功能设置目标图像质量参数，而后控制显示器275根据目标图像质量参数显示目标图像；如果利用AIPQ功能识别不到目标图像的场景，就需要控制器250利用ACR功能设置目标图像质量参数，而后控制显示器275根据目标图像质量参数显示目标图像。
如图7所示，如果目标信号源不存在于信号源白名单中，说明目标信号源目前不能支持AIPQ功能，控制器250可以利用ACR功能设置目标图像质量参数。但是，在使用ACR功能之前，控制器250还需要判断显示设备200的ACR功能是否可用，即判断显示设备200上的ACR功能是否开启。通常，支持ACR功能的显示设备200，会在其设置界面上显示有ACR功能的选项，默认状态下ACR功能是关闭的，如需开启，需要用户通过输入指令来控制其开启。
在一些实施例中，如图9所示，在目标信号源不存在于信号源白名单中的情况下，控制器250继续判断显示设备200的ACR功能是否可用，如果ACR功能可用，则控制器250可以利用ACR功能设置目标图像质量参数，而后控制器250控制显示器275根据目标图像质量参数显示目标图像；如果ACR功能不可用，则控制器250需要获取显示设备200中预设图像质量参数作为目标图像质量参数，而后再控制显示器275根据目标图像质量参数显示目标图像。
针对于上述目标信号源不存在于信号源白名单中并且ACR功能可用的情况，本申请实施例可以在AIPQ功能不可用的情况下，直接利用ACR功能设置目标图像质量参数，避免AIPQ功能不可用时使用默认图像参数造成的目标图像不能满足用户需求的问题。
如图8所示，如果利用AIPQ功能可以识别到目标图像的场景，那么控制器250才可以使用AIPQ功能设置目标图像质量参数。但是一些情况下，显示设备200的ACR功能有可能可用，如果ACR功能可用，那么控制器250就可以利用AIPQ功能和ACR功能共同设置目标图像质量参数，这样能最大程度地优化图像质量参数。
因此，在一些实施例中，如图10所示，如果利用AIPQ功能可以识别到目标图像的场景，应当先利用AIPQ功能设置目标图像对应的第一图像质量参数，控制器250控制显示器275根据第一图像质量参数显示，此时显示出的图像作为待处理图像。而后，控制器250还可以继续判断显示设备200的ACR功能是否可用。如果ACR功能不可用，则控制器250直接将AIPQ功能设置出的第一图像质量参数作为目标图像质 量参数使用，而此时待处理图像即为目标图像；如果ACR功能可用，则控制器250继续利用ACR功能设置待处理图像的目标图像质量参数，而后再控制显示器275根据目标图像质量参数显示目标图像。
针对于上述利用AIPQ功能可以识别到目标图像的场景并且ACR功能可用的情况，本申请实施例可以在AIPQ功能的基础上再次使用ACR功能，可以最大程度地优化图像质量参数，进而使得根据这种图像质量参数显示的目标图像更加满足用户的需求。
另外，在先利用AIPQ功能设置图像质量参数的基础上再利用ACR功能进一步设置目标图像质量参数，可以有效避免控制器250分别利用AIPQ功能和ACR功能设置同一个目标图像的图像质量参数时，因为两种功能的识别内容重叠而产生的图像质量参数设置冲突的问题。
如图8所示，如果利用AIPQ功能识别不到目标图像中的场景，则控制器250只能利用ACR功能设置目标图像质量参数。但是在一些情况下，显示设备200的ACR功能可能不可用，比如该功能在默认状态是关闭的，如果一直没有用户去控制开启，那么该ACR功能一直是不可用的。因此，在一些实施例中，如图11所示，如果利用AIPQ功能识别不到目标图像中的场景，那么在控制器250使用ACR功能之前，还可以继续判断显示设备200的ACR功能是否可用。如果ACR功能可用，则控制器250可以利用ACR功能设置目标图像质量参数，而后控制器250控制显示器275根据目标图像质量参数显示目标图像；如果ACR功能不可用，则控制器250需要获取显示设备200中预设图像质量参数作为目标图像质量参数，而后再控制显示器275根据目标图像质量参数显示目标图像。
针对于上述利用AIPQ功能可以识别不到目标图像的场景并且ACR功能可用的情况，本申请实施例可以利用ACR功能设置目标图像质量参数，避免了在AIPQ功能识别不到场景时使用默认图像参数造成的目标图像不能满足用户需求的问题。
并且，目前显示设备200上的AIPQ功能也是可以被控制开启或者关闭的。例如，如果用户没有预先将AIPQ功能关闭，那么控制器250如果检测到当前的目标信号源处于信号源白名单中，则设置界面上的AIPQ功能就被调整为打开状态；如果目标信号源不处于信号源白名单中，则设置界面上的AIPQ功能就被隐藏，即变为不可用。
根据以上内容可知，本申请实施例提供的显示设备200，可以结合AIPQ功能和ACR功能设置目标图像的目标图像质量参数，以使得根据目标图像质量参数最终显示的目标图像能够满足用户的观看需求。并且，当AIPQ功能无法识别目标图像的场景但是ACR功能可用时，本申请实施例的方案也可以使用ACR功能设置的目标图像质量参数，避免使用默认图像参数，进而实现高质量图像的显示，保证根据目标图像质量参数显示的目标图像能够满足用户观看显示设备200的体验要求，同时也能避免AIPQ功能和ACR功能同时使用时，图像质量参数的调整过程出现的冲突。
本申请实施例还提供了一种图像显示方法，该方法主要包括前述实施例中控制器250所执行的步骤，如图12所示，该方法主要包括：
步骤S101，获取用户需要观看的目标图像；步骤S102，利用智能图像模式切换AIPQ功能和/或自动内容识别ACR功能设置所述目标图像对应的目标图像质量参数；步骤S103，控制显示器275根据所述目标图像质量参数显示所述目标图像。
另外，在步骤S102中，还可以判断目标图像所在的目标信号源是否存在于信号源 白名单中、判断利用AIPQ功能能否识别目标图像的场景以及判断显示设备200的ACR功能是否可用。并且，根据不同的判断结果进行不同的图像质量参数设置操作。
在一些实施例中，在目标信号源不存在于信号源白名单中的情况下，判断显示设备200的ACR功能是否可用。如果ACR功能可用，则可以利用ACR功能设置目标图像质量参数，而后控制显示器275根据目标图像质量参数显示目标图像；如果ACR功能不可用，则需要获取显示设备200中预设图像质量参数作为目标图像质量参数，而后再控制显示器275根据目标图像质量参数显示目标图像。
在一些实施例中，在目标信号源存在于信号源白名单中的情况下，还要判断利用AIPQ功能能否识别到目标图像的场景。如果利用AIPQ功能可以识别到目标图像的场景，那么可以使用AIPQ功能设置目标图像质量参数，而后控制显示器275根据目标图像质量参数显示目标图像；如果利用AIPQ功能识别不到目标图像的场景，就需要利用ACR功能设置目标图像质量参数，而后控制显示器275根据目标图像质量参数显示目标图像。
在一些实施例中，在目标信号源存在于信号源白名单中并且利用AIPQ功能可以识别到目标图像的场景的情况下，应当先利用AIPQ功能设置目标图像对应的第一图像质量参数，控制显示器275根据第一图像质量参数显示，此时显示出的图像作为待处理图像。而后，还可以继续判断显示设备200的ACR功能是否可用。如果ACR功能不可用，则直接将AIPQ功能设置出的第一图像质量参数作为目标图像质量参数使用，而此时待处理图像即为目标图像；如果ACR功能可用，则继续利用ACR功能设置待处理图像的目标图像质量参数，而后再控制显示器275根据目标图像质量参数显示目标图像。
在一些实施例中，在目标信号源存在于信号源白名单中并且利用AIPQ功能识别不到目标图像的场景的情况下，也要判断显示设备的ACR功能是否可用。如果ACR功能可用，则可以利用ACR功能设置目标图像质量参数，而后控制显示器275根据目标图像质量参数显示目标图像；如果ACR功能不可用，则需要获取显示设备200中预设图像质量参数作为目标图像质量参数，而后再控制显示器275根据目标图像质量参数显示目标图像。
本申请实施例中，结合上述目标图像所在的目标信号源是否存在于信号源白名单中、利用AIPQ功能能否识别目标图像的场景以及显示设备200的ACR功能是否可用的各种结果，还可以形成如图13所示的图像显示方法。
如图13所示，针对于目标信号源不存在于信号源白名单中并且ACR功能可用的情况，本申请实施例可以在AIPQ功能不可用的情况下，直接利用ACR功能设置目标图像质量参数，避免AIPQ功能不可用时使用默认图像参数造成的目标图像不能满足用户需求的问题。
如图13所示，针对于利用AIPQ功能可以识别到目标图像的场景并且ACR功能可用的情况，本申请实施例可以在AIPQ功能的基础上再次使用ACR功能，可以最大程度地优化图像质量参数，进而使得根据这种图像质量参数显示的目标图像更加满足用户的需求，同时也能避免AIPQ功能和ACR功能同时使用时，图像质量参数的调整过程出现的冲突。
如图13所示，针对于利用AIPQ功能可以识别不到目标图像的场景并且ACR功 能可用的情况，本申请实施例可以利用ACR功能设置目标图像质量参数，避免了在AIPQ功能识别不到场景时使用默认图像参数造成的目标图像不能满足用户需求的问题。
为了方便解释，已经结合具体的实施方式进行了上述说明。但是，上述示例性的讨论不是意图穷尽或者将实施方式限定到上述公开的具体形式。根据上述的教导，可以得到多种修改和变形。上述实施方式的选择和描述是为了更好的解释原理以及实际的应用，从而使得本领域技术人员更好的使用所述实施方式以及适于具体使用考虑的各种不同的变形的实施方式。
