Description

电视机的能效控制方法、装置及电视机
本申请要求于2016年3月30日提交中国专利局、申请号为201610191462.5、发明名称为“电视机的能效控制方法、装置及电视机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及电视机技术领域，尤其涉及一种电视机的能效控制方法、装置及电视机。
背景技术
绿色低碳、节能环保是社会关注的热点，为了使电视行业达到节能环保的要求，国家已正式实施《平板电视能效限定值及能效等级》标准，其中，一个重要的指标就是电视机的能效指数，即显示面积×亮度÷功耗。其中，电视机的能效指数可分为三级，一级能效指数为1.4cd/w，代表当前市场同类产品的最高水平；二级能效指数为1.0cd/w，代表当前市场同类产品的平均水平；三级能效指数为0.6cd/w，为市场的准入等级，主要用于淘汰市场上高能耗产品。因此，如何对电视机进行能效控制是本领域技术人员必须面对的问题。
电视机的能效控制可以分别从软件方面和硬件方面来实现。其中，在软件方面可以通过对帧数据进行相应的处理，降低画面质量，来提高电视机的能效。
通常情况下，电视机还配置有外部设备接口(例如，USB接口)，用户可以根据需求通过外部设备接口自行连接外部设备，对电视机的功能进行拓展，给用户带来丰富的个性化体验。但是，由于外部设备通常为第三方设备，其内部程序固化，设置有权限，使得外部设备输入的帧数据不能直接获得，从而无法控制电视机的能效。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装 置和方法的例子。
图1为本公开实施例提供的一种场景示意图，图中包括电视机1，电视机1上设有外部设备接口(例如，USB接口)，用户可以通过外部设备接口连接外部设备2，对电视机1的功能进行扩展，例如接收一些特定的频道信号或视频资源等。
其中，图1所示仅为本公开的一种场景示意图，图中电视机1以及与电视机1相连的外部设备2的具体类型、数量和对应关系都不限于图1中公开的具体形式，例如，外部设备2的数量可以为两个或两个以上的多个，外部设备2与电视机1的连接方式可以采用无线连接等，本领域的技术人员可以根据自己的需求自行选择，本公开对此不做限定。
图2为本公开实施例提供的一种电视机的能效控制方法流程示意图，如图2所示，该电视机的能效控制方法，包括如下步骤：
步骤S100：从应用层获取外部设备输入的帧数据的缓存地址。
在本公开实施例中，当外部设备通过外部设备接口与电视机连接后，外部设备中的帧数据通过外部设备接口传输至外部设备适配层，外部设备适配层将帧数据传输至缓存器中进行缓存，且将缓存器中帧数据的缓存地址传输至应用层。应用层接收到帧数据的缓存地址后，将缓存地址传输至显示适配层，显示适配层根据所述缓存地址在缓存器中查找与缓存地址相对应的帧数据，进而根据所述帧数据在显示屏上显示相应的图像。
虽然根据外部设备设定的程序，外部设备输出的帧数据在硬件层和适配层均处于封装状态，使帧数据无法在硬件层和适配层直接获取，但是，当外部设备适配层将帧数据传输至缓存器中进行缓存后，会将缓存器中的缓存地址传输至应用层。因此，在本公开实施例中，可以从应用层获取外部设备输入的帧数据的缓存地址。
步骤S200：查找与所述缓存地址相对应的帧数据。
由于缓存器中的帧数据和缓存地址具有一一映射的关系，因此，当缓存地址确定之后，即可唯一地确定帧数据。此时，由于已经在应用层获取到帧数据的缓存地址，因此，可以根据缓存地址，在缓存器中查找相对应的帧数据。其中，本公开实施例并不对帧数据的查找方式做具体限定，本领域技术人员可以根据实际需求选择不同的查找方式，其均应当落入本公开的保护范围之内。
步骤S300：从所述帧数据中提取出能耗参数信息。
电视机的能效是显示屏面积与能耗的比值，在显示屏面积一定的情况下，为了提高电视机的能效，只能降低电视机的能耗。由于显示屏上显示的图像质量可以影响电视机的能耗(图像质量越高，电视机的能耗越高)，因此，可以根据显示屏上显示的图像信息(即，帧数据)，确定电视机的能耗，进而对电视机执行相应的能效控制策略。
在本公开实施例中，帧数据中包含图像的详细信息，包括亮度、对比对、分辨率、像素值等。由于在本公开实施例中需要根据帧数据对电视机的能效进行控制，因此，在帧数据中提取与能耗有关的信息，即能耗参数信息。
步骤S400：根据所述能耗参数信息对所述电视机进行能效控制。
在本公开实施例中，能耗参数信息确定之后，即可根据能耗参数信息对电视机执行相应的能效控制策略。
例如，当能耗参数信息大于预设的能耗参数信息阈值时，说明电视机的当前能耗已经超出设定的能耗标准，则降低电视机的当前能耗，实现对电视机的能效控制；当能耗参数信息小于或等于预设的能耗参数信息阈值时，说明电视机的当前能耗没有超出设定的能耗标准，则保持电视机的当前能耗状态。其中，本公开实施例对降低电视机当前能耗的具体方式不做限定，本领域技术人员可以根据实际需要降低电视机相应器件的功耗，其均应当处于本公开的保护范围之内。
在本公开实施例中，通过应用层获取帧数据的缓存地址，根据缓存地址，查找与所述缓存地址相对应的帧数据，实现对外部设备输入的帧数据的获取，进而根据帧数据的相关信息，对电视机进行能效控制，实现外部设备输入帧数据时，电视机的能效控制。
本公开的另一实施例如图3所示，其在图2所示实施例的步骤S300可以包括以下步骤：
步骤S301：提取所述帧数据中的亮度数据作为能耗参数信息。
帧数据中包含用于在显示屏上显示的图像的详细信息，包括亮度、对比对、分辨率、像素值等。由于图像的亮度对电视机的能耗影响较大，因此，在本公开实施例中，可以提取帧数据中的亮度数据作为能耗参数信息。
当然，以上所示仅是本公开列举的一种具体实现方式，本领域技术人员可以 根据实际需要在帧数据中提取其它信息作为能耗参数信息，其均应当处于本公开的保护范围之内。例如，可以提取帧数据中的分辨率数据作为能耗参考信息。
本公开的另一实施例如图4所示，其在图3所示实施例的步骤S400中可以包括以下步骤：
步骤S401：判断所述亮度数据是否大于预设的亮度阈值。
容易理解的是，若电视机的当前能效符合能效标准，则不需要对电视机进行能效控制；若电视机的当前能效不符合能效标准，则需要降低电视机的当前能耗，即对电视机进行能效控制，使其达到能效标准。
在本公开实施例中，根据电视机的能效标准设定亮度阈值，即以亮度阈值作为电视机是否需要执行能效控制的判断标准。具体为，判断所述亮度数据是否大于预设的亮度阈值，当所述亮度数据大于预设的亮度阈值时，执行步骤S402；否则，结束流程。
步骤S402：对所述电视机执行能效控制。
电视机的能效是显示屏面积与能耗的比值，在显示屏面积一定的情况下，为了提高电视机的能效，只能降低电视机的能耗。在本公开实施例中，可以通过降低电视机能耗的方式提高电视机的能效，进而将电视机的能效控制在标准水平，实现电视机的能效控制。其中，本公开实施例对降低电视机能耗的具体方式不做限定，本领域技术人员可以根据实际需要采用不同的技术手段，其均应当落入本公开的保护范围之内。
由于图像的亮度对电视机的能耗影响较大，因此，以帧数据中的亮度数据作为是否需要执行能效控制的判定标准可以提高能效控制的准确度。
本公开的另一实施例如图5所示，其在图4所示实施例的步骤S402中可以包括以下步骤：
步骤S4021：将所述帧数据中的亮度数据调整至所述亮度阈值。
对于电视机而言，能耗主要取决于显示屏，即要降低电视机的整机能耗，就是要降低显示屏的能耗。其中，显示屏的能耗主要用来显示图像，因此，可以通过调整显示屏显示的图像降低显示屏的能耗。
另外，由于图像的亮度对能耗的影响较大，因此，在本公开实施例中，通过 调整图像的亮度降低显示屏的能耗，具体为，将所述帧数据中的亮度数据调整至所述亮度阈值。其中，帧数据即代表显示屏将要显示的图像的数据，帧数据中的亮度数据即代表图像的亮度。
例如，图像的当前亮度为500cd/m2，预设的亮度阈值为450cd/m2。经比较，判断图像的当前亮度(500cd/m2)大于预设的亮度阈值(450cd/m2)，则将图像的亮度调整至亮度阈值，即将图像的亮度调整至450cd/m2。由于亮度阈值是根据能效标准设定的亮度值，因此，将亮度数据调整至亮度阈值大小即可使电视机的能效达到能效标准。
在本公开实施例中，以亮度阈值为标准对图像的亮度进行调整，可以提高电视机能效控制的精度。
本公开的另一实施例如图6所示，其在图4所示实施例的步骤S402中可以包括以下步骤：
步骤S4022：将所述帧数据中的亮度数据调整至当前亮度数据的70％-80％。
本公开实施例与上述实施例基本相似，其同样通过降低图像的亮度降低电视机的能耗。其不同之处在于，在本公开实施例中，当判断所述亮度数据大于预设的亮度阈值时，直接将显示屏显示的图像的亮度调整至当前亮度的70％-80％，具体为，将所述帧数据中的亮度数据调整至当前亮度数据的70％-80％，其中，亮度数据的调整比例可以为70％-80％中的任一数据，本公开对此不做限制。
例如，图像的当前亮度为500cd/m2，预设的亮度阈值为450cd/m2，亮度数据的调整比例为80％。经比较，判断图像的当前亮度(500cd/m2)大于预设的亮度阈值(450cd/m2)，则将图像的亮度调整至当前亮度的80％，即将图像的亮度调整至400cd/m2。由于调整后的图像亮度低于亮度阈值，因此，通过对图像的亮度调整使电视机达到能效标准，实现对电视机的能效控制。
也就是说，在本公开实施例中不再以亮度阈值为标准对图像的亮度进行调整，而是直接根据图像的当前亮度等比例降低，减小电视机的数据处理量，易于实现。
本公开的另一实施例如图7所示，其在图4所示实施例的步骤S402中可以包括以下步骤：
步骤S4023：将所述电视机的背光灯亮度调整至当前背光灯亮度的70％-80％。
显示屏是通过背光灯来提供背光亮度，电视机打开后，背光灯就一直处于点亮状态，因此，在本公开实施例中，可以通过调整背光灯的亮度，降低电视机的能耗，进而实现电视机的能效控制。
其中，本领域技术人员可以根据实际需要选择70％-80％之中的任一数值作为背光灯的调整比例，本公开对此不做限制。
由于背光灯仅是电视机中的发光器件，因此，通过调整背光灯的亮度对电视机进行能效控制易于实现。
本公开的另一实施例如图8所示，其在图2所示实施例的步骤S200可以包括以下步骤：
步骤S201：查找与所述缓存地址相对应的两帧以上的帧数据，其中，所述两帧以上的帧数据为连续的帧数据。
由于帧数据为连续的数据流，因此，可以根据缓存地址，查找两帧以上的帧数据，用于在后续步骤中对帧数据的类型进行判断。其中，帧数据的数量可以为两帧以上的任意数值，例如，三帧、四帧或五帧等，本公开对此不做限制。
本公开的另一实施例如图9所示，其在图8所示实施例的步骤S300中可以包括以下步骤：
步骤S311：判断所述帧数据是否为动态帧。
通常情况下，电视机播放的画面包括动态画面(例如，电视剧或电影)和静态画面(例如，静态图片)。其中，动态画面所对应的数据帧为动态帧，静态画面所对应的数据帧为静态帧。
由于电视机播放动态画面时的能耗较高，播放静态画面时的能耗较低，因此，仅需在电视机播放动态画面时对电视机进行能效控制。在本公开实施例中，当查找到与缓存地址相对应的帧数据后，首先判断帧数据是否为动态帧，当判断所述帧数据为动态帧时进入步骤S312；否则，结束流程。
步骤S312：提取所述帧数据中的亮度数据作为能耗参数信息。
在本公开实施例中，当帧数据为动态帧时，提取所述帧数据中的亮度数据作为能耗参数信息。也就是说，只有当帧数据为动态帧时，才提取帧数据中的亮度数据以在后续步骤中对电视机进行能效控制；当帧数据为静态帧时，不需要对电 视机进行能效控制，则不需要提取帧数据中的亮度数据。
在本公开实施例中，以帧数据的类型作为电视机的能效控制条件，实现对不同的帧数据采用不同的能效控制策略，进而提高电视机的能效控制精度。
本公开的另一实施例如图10所示，其在图9所示实施例的步骤S311可以包括以下步骤：
步骤S3111：将所述两帧以上的帧数据进行两两比对。
在本公开实施例中，每一帧帧数据代表一个图像，将帧数据进行两两比对即将每一帧所代表的图像进行两两比对。
例如，帧数据共有两帧，分别为第一帧数据和第二帧数据，则将第一帧数据和第二帧数据进行比对；再如，帧数据共有三帧，分别为第一帧数据、第二帧数据和第三帧数据，则将第一帧数据和第二帧数据进行比对，将第一帧数据和第三帧数据进行比对，将第二帧数据和第三帧数据进行比对。
步骤S3112：判断是否存在两帧的帧数据不同。
若两帧的帧数据相同，则代表两个图像相同，即电视机播放的图像为静态图像；若两帧的帧数据不同，则代表两个图像不同，即电视机播放的图像为动态图像。因此，可以通过不同帧之间的比对结果判断帧数据的类型。
在本公开实施例中，当存在任意两帧的帧数据不同时，进入步骤S3113；否则，结束流程。
例如，当帧数据包括三帧，分别为第一帧数据、第二帧数据和第三帧数据时，当其中的任意两帧的帧数据不同时，即确定所述帧数据为动态帧，进入步骤S3113。
步骤S3113：确定所述帧数据为动态帧。
当存在两帧的帧数据不同时，说明电视机播放的两个图像不同，则电视机播放的图像为动态图像，动态图像所对应的帧数据为动态帧。
在本公开实施例中，通过对任意两帧的帧数据进行对比，判断帧数据的类型，判断结果准确可靠。
需要指出的是，在本公开实施例中以缓存器为例对帧数据的缓存位置进行示例性说明，但并不应当将其作为本公开保护范围的限制，本领域的技术人员可以 根据实际需要采用其它的存储器件对帧数据进行缓存，其均应当落入本公开的保护范围之内。
基于同一公开构思，本公开实施例还提供了一种电视机的能效控制装置。图11为本公开实施例提供的一种电视机的能效控制装置结构示意图，如图11所示，该电视机的能效控制装置包括：
缓存地址获取模块11100，被配置为从应用层获取外部设备输入的帧数据的缓存地址。
在本公开实施例中，当外部设备通过外部设备接口与电视机连接后，外部设备中的帧数据通过外部设备接口传输至外部设备适配层，外部设备适配层将帧数据传输至缓存器中进行缓存，且将缓存器中帧数据的缓存地址传输至应用层。应用层接收到帧数据的缓存地址后，将缓存地址传输至显示适配层，显示适配层根据所述缓存地址在缓存器中查找与缓存地址相对应的帧数据，进而根据所述帧数据在显示屏上显示相应的图像。
虽然根据外部设备设定的程序，外部设备输出的帧数据在硬件层和适配层均处于封装状态，使帧数据无法在硬件层和适配层直接获取，但是，当外部设备适配层将帧数据传输至缓存器中进行缓存后，会将缓存器中的缓存地址传输至应用层。因此，在本公开实施例中，可以从应用层获取外部设备输入的帧数据的缓存地址。
帧数据查找模块11200，被配置为查找与所述缓存地址相对应的帧数据。
由于帧数据和缓存地址具有一一映射的关系，因此，当缓存地址确定之后，即可唯一地确定帧数据。此时，由于已经在应用层获取到帧数据的缓存地址，因此，可以根据缓存地址，查找相对应的帧数据。
能耗参数信息提取模块11300，被配置为从所述帧数据中提取出能耗参数信息。
电视机的能效是显示屏面积与能耗的比值，在显示屏面积一定的情况下，为了提高电视机的能效，只能降低电视机的能耗。由于显示屏上显示的图像质量可以影响电视机的能耗(图像质量越高，电视机的能耗越高)，因此，可以根据显示屏上显示的图像信息(即，帧数据)，确定电视机的能耗，进而对电视机执行相应的能效控制策略。
在本公开实施例中，帧数据中包含图像的详细信息，包括亮度、对比对、分辨率、像素值等。由于在本公开实施例中需要根据帧数据对电视机的能效进行控制，因此，在帧数据中提取与能耗有关的信息，即能耗参数信息。

本公开另一实施例，如图13所示，图12中的能效控制模块，包括：

在本公开实施例中，根据电视机的能效标准设定亮度阈值，即以亮度阈值作为电视机是否需要执行能效控制的判断标准。

由于图像的亮度对电视机的能耗影响较大，因此，以帧数据中的亮度数据作为是否需要执行能效控制的判定标准可以提高能效控制的准确度。
