此外，为实现上述目的，本申请还提出了一种计算机可读存储介质，所述计算机可读存储介质上存储有节目播放程序，所述节目播放程序被处理器执行时实现如上述任一项所述的节目播放方法的步骤。
本申请技术方案提出了一种节目播放方法，用于显示终端，通过获取目标 用户与所述显示终端的观看距离；基于所述观看距离获得选定分辨率转换算法；利用所述选定分辨率转换算法对获取到的目标节目进行分辨率转换，获得结果节目；播放所述结果节目。
由于，现有节目播放方法，显示终端利用显示终端具有的最复杂的分辨率转换算法，将目标节目转换为结果节目，此时，分辨率转换算法需要占用显示终端的大量运算资源和存储资源，导致显示终端的资源浪费，显示终端的用户体验较差。而用户在显示终端观看节目时，不同的观看距离对应的人眼可感知的最高分辨率也是不同的，本申请的播放方法，显示终端基于与目标用户的观看距离，确定与观看距离对应的选定分辨率转换算法，以利用所述选定分辨率转换算法对获取到的目标节目进行分辨率转换，获得结果节目，并不是利用显示终端具有的最复杂的分辨率转换算法对目标节目数据进行分辨率转换，使得显示终端在保证用户观看体验的前提下，运算资源和存储资源消耗降低。所以，利用本申请的节目播放方法，降低了显示终端的资源消耗，提升了用户体验。

基于上述硬件结构，提出本申请节目播放方法的实施例。
参照图2，图2为本申请节目播放方法一实施例的流程示意图，所述方法用于显示终端，所述方法包括以下步骤：
步骤S11：获取目标用户与所述显示终端的观看距离。
步骤S12：基于所述观看距离获得选定分辨率转换算法。
步骤S13：利用所述选定分辨率转换算法对获取到的目标节目进行分辨率转换，获得结果节目。
步骤S14：播放所述结果节目。
需要说明的是，本申请的执行主体是显示终端，显示终端安装有节目播放程序，显示终端执行节目播放程序时，实现本申请的节目播放方法。目标用户可以是正在使用显示终端的用户。
可以理解的是，在进行步骤S11时，可以是显示终端开启本申请节目播放程序的功能之后，显示终端时时刻刻都在进行观看距离的获取，显示终端每获取到一次新的观看距离，则执行一次本申请的节目播放方法；还可以是，在显示终端开启之后，显示终端时时刻刻进行观看距离的获取。同时，目标节目可以是显示终端正在播放的视频，也可以是显示终端获取的游戏数据和图片等。
具体应用中，目标节目的分辨率通常较低，例如480P、720P或1080P等，显示终端的尺寸通常较大，例如65寸等。为了保证用户的观看体验，需要将目标节目进行分辨率提升，以在较大的显示终端上播放清晰的节目。
进一步的，如图3所示，步骤S12包括：
步骤S121，基于所述观看距离获得增益参数；
步骤S122，在分辨率转换算法集合中确定出与所述增益参数对应的选定分辨率转换算法，所述分辨率转换算法集合包括不同增益参数对应的分辨率转换算法。
具体的，如图4所示，所述基于所述观看距离获得增益参数的步骤之前， 所述方法还包括：
步骤S123，获取所述显示终端的预置像素数量和预置屏幕尺寸；
相应的，所述基于所述观看距离获得增益参数的步骤，包括：
步骤S124，基于所述观看距离、所述预置像素数量和所述预置屏幕尺寸获得所述增益参数。
如图5所示，所述基于所述观看距离、所述预置像素数量和所述预置屏幕尺寸获得所述增益参数的步骤，包括：
步骤S125，基于所述预置屏幕尺寸和所述预置像素数量获得像素间距；
步骤S126，基于所述观看距离获得人眼分辨间距；
步骤S127，基于所述像素间距和所述人眼分辨间距，获得所述增益参数。
首先，需要说明的是，所述基于所述预置屏幕尺寸和所述预置像素数量获得像素间距的步骤，包括：基于第一预设参数、所述预置屏幕尺寸和所述预置像素数量，利用公式一，获得像素间距；
所述公式一为：
Figure PCTCN2021104949-appb-000001
其中，x为所述第一预设参数，x可以取2.5，dp为所述像素间距，L为所述预置屏幕尺寸，Pt为所述预置像素数量；
所述基于所述观看距离获得人眼分辨间距的步骤，包括：基于第二预设参数和所述观看距离，利用公式二，获得人眼分辨间距；
所述公式二为：
du＝y×D
其中，y为所述第二预设参数，y可以取0.0004，D为所述观看距离，du为所述人眼分辨间距；
所述基于所述像素间距和所述人眼分辨间距，获得所述增益参数的步骤，包括：基于所述像素间距和所述人眼分辨间距，利用公式三，获得所述增益参数；
所述公式三为：
Figure PCTCN2021104949-appb-000002
其中，K为所述增益参数，可以理解的是，在本申请中，增益参数在区间(0,1]中。
其次，分辨率转换算法集合包括多种分辨率转换算法，不同的分辨率转换算法对应的运算复杂度不同，即：在对相同分辨率的节目进行分辨率转换时，不同的分辨率转换算法对应的转换后节目的分辨率不同；分辨率转换算法越复杂，其对应的转换后节目的分辨率越高，在进行分辨率转换时，消耗的资源越多(复杂性、资源占用率和电能消耗量等越高)。
本申请中，分辨率转换算法集合包括三种分辨率转换算法：A分辨率转换算法、B分辨率转换算法和C分辨率转换算法，A分辨率转换算法、B分辨率转换算法和C分辨率转换算法等级依次降低(等级越高，复杂性、资源占用率和电能消耗量等越高，转换后节目的分辨率越高)。同时，增益参数越高，对应的分辨率转换算法等级越高。在本申请中，在增益参数为1时，对应等级最高的A分辨率转换算法，将增益参数对应的(0,1)区间划分为两个区间，一个区间对应C分辨率转换算法，另一个区间对应B分辨率转换算法；其中，将增益参数对应的(0,1)区间划分为两个区间的具体划分策略，此处不做限定。
进一步的，如图6所示，步骤S13之前，所述方法还包括：
步骤S131，基于所述增益参数和所述显示终端的预置分辨率，获得选定分辨率；
步骤S13包括：
步骤S132，利用所述选定分辨率转换算法将所述目标节目的分辨率转换为所述选定分辨率，以获得所述结果节目。
其中，如图7所示，步骤S13具体包括：
步骤S133，在所述目标节目的分辨率小于预设分辨率时，对所述目标节目 进行预插值处理，以获得具有所述预设分辨率的预处理节目，并利用所述选定分辨率转换算法将所述预处理节目的分辨率转换为所述选定分辨率，获得所述结果节目；或，在所述目标节目的分辨率大于或等于所述预设分辨率时，利用所述选定分辨率转换算法将所述目标节目的分辨率转换为所述选定分辨率，获得所述结果节目。
需要说明的是，参照上述描述，增益参数和选定分辨率是具有映射关系的，增益参数和选定分辨率可以是线型关系(通常对于一个固定的显示终端，预置分辨率是定值，预置分辨率即为线型关系中的参数)，增益参数和选定分辨率也可以是非线型关系，此处不做限定。其对应关系是：增益参数越大，选定分辨率越大即可。
具体应用中，预设分辨率可以是用户根据需求设定的，本申请不做限制。
进一步的，通常，所述选定分辨率小于所述预置分辨率；如图8所示，步骤S14之前，所述方法还包括：
步骤S141，对所述结果节目进行图像拉伸处理，获得具有所述预置分辨率的输出节目；
相应的步骤S14包括：
步骤S142，播放所述输出节目。
例如，目标节目是480P标清节目；显示终端为65寸(预置屏幕尺寸)4K(预置分辨率)，即L为65寸，预置分辨率为4K*2K，对应的预设像素数量为Pt＝4K*2K；预插值处理部分对应的预设分辨率为2K*1K，目标用户的观看距离为D为4m，即，增益参数和选定分辨率是线型关系。
首先，显示终端将获取到的480P标清节目，确定其分辨率小于预设分辨率，对其预插值处理，获得分辨率为2K*1K的预处理节目。基于第一预设参数(2.5)、所述预置屏幕尺寸和所述预置像素数量，利用公式一，获得像素间距dp为0.00094米，并基于第二预设参数(0.0004)和所述观看距离，利用公式二，获得人眼分辨间距du为0.0016米，最后，基于所述像素间距和所述人眼分辨间 距，利用公式三，获得所述增益参K＝0.5875。基于增益K为0.5875，在分辨率转换算法集合中确定C分辨率转换算法为选定分辨率转换算法。
其次，基于增益参数和选定分辨率线型关系，获得选定分辨率：选定分辨率＝(0.5875*4K)*(0.5875*2K)＝(2.35K)*(1.175K)；并利用所述C分辨率转换算法将所述预处理节目的分辨率(分辨率为2K*1K)转换为所述选定分辨率(2.35K*1.175K)，获得所述结果节目。
最后，显示终端将具有选定分辨率(2.35K)*(1.175K)的结果节目，进行图像拉伸处理，转换为分辨率为4K*2K的输出节目，并驱动显示终端的屏幕进行显示。
在目标用户观看过程中，获取的目标用户的观看距离D变化，则再次执行本申请的节目播放方法。比如，获取目标用户与屏幕的观看距离D＝2时，du为0.0008，则得到增益参数K＝1，则选择A分辨率转换算法对预处理节目晰度提升处理，以得到最终的输出节目的分辨率为4K*2K。
本申请技术方案提出了一种节目播放方法，用于显示终端，通过获取目标用户与所述显示终端的观看距离；基于所述观看距离获得选定分辨率转换算法；利用所述选定分辨率转换算法对获取到的目标节目进行分辨率转换，获得结果节目；播放所述结果节目。
由于，现有节目播放方法，显示终端利用显示终端具有的最复杂的分辨率转换算法，将目标节目转换为结果节目，此时，分辨率转换算法需要占用显示终端的大量运算资源和存储资源，导致显示终端的资源浪费，显示终端的用户体验较差。而用户在显示终端观看节目时，不同的观看距离对应的人眼可感知的最高分辨率也是不同的，本申请的播放方法，显示终端基于与目标用户的观看距离，确定与观看距离对应的选定分辨率转换算法，以利用所述选定分辨率转换算法对获取到的目标节目进行分辨率转换，获得结果节目，并不是利用显示终端具有的最复杂的分辨率转换算法对目标节目数据进行分辨率转换，使得显示终端在保证用户观看体验的前提下，运算资源和存储资源消耗降低。所以， 利用本申请的节目播放方法，降低了显示终端的资源消耗，提升了用户体验。
通过人眼分辨间距与像素间距之间的倍率，来选择预先设置的不同复杂程度级别的分辨率转换算法，来获得符合人眼实际观看要求的节目。可见，只有在显示终端屏幕较大、用户观看距离较近时，显示终端确定的选定分辨率转换算法复杂度才会较高，当用户处于较远距离，或显示终端尺寸较小，显示终端不会采用较复杂的分辨率转换算法进行分辨率转换，避免显示终端资源浪费，节省电能消耗，提升用户体验以及更加节能环保。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
