移动终端视频的呈现方法及装置 技术领域 本发明涉及通信领域， 具体而言， 涉及一种移动终端视频的呈现方法及装置。 背景技术 随着移动终端硬件技术的飞速发展， 越来越多新颖、 充满创意的新功能被引入移 动终端领域， 以增强手机的实用性和娱乐性， 为用户带来了更加丰富的操作体验和乐 趣。 近感感应功能就是其中的一种。 要实现近感感应功能， 首先， 要在移动终端中植 入近感感应器， 又称位移感应器。 通常情况下， 设置在手机听筒的两侧或者凹槽中。 其原理在于通过获取被监测对象的物理变化量， 计算出从传感器到被检测对象物的距 离。 目前， 移动终端的硬件支持在逐步升级， 用户的多媒体体验也正朝着多元化方向 发展， 尤其是， 视频播放器适用的文件格式已经从传统分辨率较低的， 如： .3gp, .flv 等格式转化为可以播放各种高清， 超清的， 如： .avi, .mkv 等格式的文件。 上述文件 类型通常采用视频文件与字幕文件分开处理的方式， 当视频播放时， 如果手机屏幕放 置太远， 视频上字幕或者声音就会显得较小； 如果手机屏幕放置太近， 又会觉得字幕 或者声音太大。 因此， 在相关技术中， 缺少用户在移动终端上观看视频时， 移动终端屏幕上的字 幕或者声音无法随着用户与移动终端屏幕之间距离的改变而做出适应性调整的解决方 案。 发明内容 本发明提供了一种移动终端视频的呈现方法及装置， 以至少解决相关技术中， 用 户在移动终端上观看视频时， 移动终端屏幕上的字幕无法随着用户与移动终端屏幕之 间距离的改变而做出适应性调整的问题。 根据本发明的一个方面， 提供了一种移动终端视频的呈现方法。 根据本发明的移动终端视频的呈现方法包括： 获取移动终端视频所在的屏幕与观 看移动终端视频的人眼之间的距离； 根据获取到的距离调节移动终端视频中字幕的大 小， 其中， 字幕的大小与获取到的距离成递增关系。 上述获取屏幕与人眼之间的距离包括： 感应获取到的距离是否等于预设距离； 在 不等于预设距离时， 确定获取到的距离相对于预设距离的偏移位移； 采用偏移位移和 预设距离计算出获取到的距离。 上述根据获取到的距离调节移动终端视频中字幕的大小包括： 确定获取到的距离 所在的预设距离区间对应的字幕大小； 将移动终端视频中字幕的大小调节至与预设距 离区间对应的字幕大小。 在根据获取到的距离调节移动终端视频中字幕的大小时， 还包括： 根据获取到的 距离调节移动终端视频中音量的大小，其中，音量的大小与获取到的距离成递增关系。 上述根据获取到的距离调节移动终端视频中音量的大小包括： 确定获取到的距离 所在的预设距离区间对应的音量大小； 将移动终端视频中字幕的大小调节至与预设距 离区间对应的音量大小。 根据本发明的另一方面， 提供了一种移动终端视频的呈现装置。 根据本发明的移动终端视频的呈现装置包括： 获取模块， 设置为获取移动终端视 频所在的屏幕与观看移动终端视频的人眼之间的距离； 第一调节模块， 设置为根据获 取到的距离调节移动终端视频中字幕的大小， 其中， 字幕的大小与获取到的距离成递 增关系。 上述获取模块包括： 感应单元， 设置为感应获取到的距离是否等于预设距离； 第 一确定单元， 设置为在感应单元输出为否时， 确定获取到的距离相对于预设距离的偏 移位移； 计算单元， 设置为采用偏移位移和预设距离计算出获取到的距离。 上述第一调节模块包括： 第二确定单元， 设置为确定获取到的距离所在的预设距 离区间对应的字幕大小； 第一调节单元， 设置为将移动终端视频中字幕的大小调节至 与预设距离区间对应的字幕大小。 上述装置还包括： 第二调节模块， 设置为根据获取到的距离调节移动终端视频中 音量的大小， 其中， 音量的大小与获取到的距离成递增关系。 上述第二调节模块包括： 第三确定单元， 设置为确定获取到的距离所在的预设距 离区间对应的音量大小； 第二调节单元， 设置为将移动终端视频中字幕的大小调节至 与预设距离区间对应的音量大小。 通过本发明， 当移动终端播放视频时， 采用实时获取该视频所在的屏幕与观看该 视频的人眼之间的距离， 并根据获取到的距离实时调节视频中字幕的大小， 如果屏幕 靠近用户， 则视频中字幕的大小就会随距离的减小而变小； 如果屏幕远离用户， 则视 频中字幕的大小就会随距离的增大而变大， 解决了相关技术中， 用户在移动终端上观 看视频时， 移动终端屏幕上的字幕无法随着用户与移动终端屏幕之间距离的改变而做 出适应性调整的问题， 进而达到了移动终端屏幕与用户之间距离的变化并不影响用户 观看移动终端视频中的字幕， 用户体验友好的效果。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部分， 本发 明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图 中： 图 1是根据本发明实施例的移动终端视频的呈现方法的流程图； 图 2根据本发明优选实施例的移动终端视频的呈现方法的流程图； 图 3是根据本发明优选实施例的移动终端视频初始化设置界面的示意图； 图 4是根据本发明实施例的移动终端视频的呈现装置的结构框图； 图 5是根据本发明优选实施例的移动终端视频的呈现装置的结构框图； 以及 图 6是根据本发明优选实施例的移动终端视频的呈现装置的示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在不冲突的 情况下， 本申请中的实施例及实施例中的特征可以相互组合。 图 1是根据本发明实施例的移动终端视频的呈现方法的流程图。 如图 1所示， 该 方法主要包括以下处理： 步骤 S102: 获取移动终端视频所在的屏幕与观看移动终端视频的人眼之间的距 离； 步骤 S104: 根据获取到的距离调节移动终端视频中字幕的大小， 其中， 字幕的大 小与获取到的距离成递增关系。 相关技术中， 用户在移动终端上观看视频时， 移动终端屏幕上的字幕无法随着用 户与移动终端屏幕之间距离的改变而做出适应性调整。 采用如图 1所示的方法， 基于 近感感应， 能够根据人眼与移动终端屏幕之间的距离动态地改变移动终端视频中字幕 的大小， 从而极大地改善了用户的视觉体验。 在优选实施例中， 可以通过在移动终端上安装一个服务软件作为近感感应功能的 管理和控制中心， 在开机的时候被加载到移动终端的启动项中， 主要负责监控并感知 终端的近感感应事件， 待开启视频播放时候， 同步视频播放器的图像帧和服务软件的 字幕帧， 通过软件在视频播放器上层输出大小可变的动态字幕。 优选地，在步骤 S102中，获取移动终端视频所在的屏幕与观看该移动终端视频的 人眼之间的距离可以包括如下处理： 步骤 S1 : 感应上述获取到的距离是否等于预设距离； 步骤 S2: 在不等于预设距离时， 确定获取到的距离相对于预设距离的偏移位移； 步骤 S3 : 采用上述偏移位移和上述预设距离计算出获取到的距离。 在优选实施例中， 为了实时获取观看移动终端视频的人眼与移动终端屏幕之间的 距离， 通常可以初始化设置一个人眼与屏幕之间的默认距离 （即上述预设距离）， 如： 100mm。 每当人眼与屏幕之间的距离发生变化时， 可以通过获取变化后的距离相对于 默认距离的偏移位移， 即移动终端远离用户的方向为正向， 取值为正值； 移动终端靠 近用户的方向为反向， 取值为负值， 从而计算出变化后的人眼与屏幕之间的距离， 进 而调整移动终端视频中字幕的大小。 例如： 将观看移动终端视频的人眼与移动终端屏幕之间的默认距离设置为
100mm。 当移动终端向用户靠近 50mm， 由于移动方向为反向， 因此， 相对于默认距 离的偏移位移为 -50mm。 由此， 计算出当前人眼与移动终端屏幕之间的距离为 100+ ( -50) =50mm。移动终端视频中字幕因为人眼与屏幕之间的距离减小而缩小视频中字 幕的大小。 优选地，在步骤 S104中，根据获取到的距离调节移动终端视频中字幕的大小可以 包括以下操作： 步骤 S4: 确定获取到的距离所在的预设距离区间对应的字幕大小； 步骤 S5 : 将移动终端视频中字幕的大小调节至与预设距离区间对应的字幕大小。 在优选实施例中， 可以在移动终端内部预先存储近感设置索引表， 如表 1所示， 表 1
Figure imgf000007_0001
如上例所述， 观看移动终端视频的人眼与移动终端屏幕之间的默认距离设置为
100mm, 该默认距离位于距离区间 100mm-200mm， 该距离区间对应的字幕大小为 10 号字。 由于变化后的人眼与移动终端屏幕之间的距离为 50mm， 该当前距离位于距离 区间 <100mm， 该距离区间对应的字幕大小为 6号字。 需要说明的是， 上述根据获取到的距离调节移动终端视频中字幕的大小的方式并 不局限于查找近感设置索引表， 还可以包括但不限于以下方式： 方式一、 观看移动终端视频的人眼与移动终端屏幕之间的默认距离设置为 100mm, 视频中预设的字幕大小为 10 号字， 移动终端屏幕与人眼之间的距离每减小 10mm, 字幕大小即减小 1号字； 移动终端屏幕与人眼之间的距离每增加 10mm， 字幕 大小即增大 1号字； 方式二、 在观看移动终端视频的人眼与移动终端屏幕之间的距离区间以等差的方 式增长 （如： 差值为 50mm)， 视频中字幕的大小也以等差的方式增长 （如： 差值为 2 号字）， 最小字体可以预设为 8号字。 例如： 0mm-50mm对应 8号字， 50mm-100mm 对应 10号字， 100mm-150mm对应 12号字。 优选地，当执行步骤 S104,根据获取到的距离调节移动终端视频中字幕的大小时， 上述方法还可以包括： 根据获取到的距离调节移动终端视频中音量的大小， 其中， 音 量的大小与获取到的距离成递增关系。 优选地， 上述根据获取到的距离调节移动终端视频中音量的大小可以包括以下操 作： 步骤 S4: 确定获取到的距离所在的预设距离区间对应的音量大小； 步骤 S5 : 将移动终端视频中字幕的大小调节至与预设距离区间对应的音量大小。 在优选实施例中， 如上述表 1所示， 观看移动终端视频的人眼与移动终端屏幕之 间的默认距离设置为 100mm, 该默认距离位于距离区间 100mm-200mm， 该距离区间 对应的音量大小为 2级。 如果变化后的人眼与移动终端屏幕之间的距离为 50mm， 该 当前距离位于距离区间<100mm， 该距离区间对应的音量大小为 1级。 需要说明的是， 上述根据获取到的距离调节移动终端视频中音量的大小的方式并 不局限于查找近感设置索引表， 还可以包括但不限于以下方式： 方式一、 观看移动终端视频的人眼与移动终端屏幕之间的默认距离设置为
100mm，视频中预设的音量大小为 2级，移动终端屏幕与人眼之间的距离每减小 50mm， 音量大小即减小 1级； 移动终端屏幕与人眼之间的距离每增加 50mm， 音量大小即增 大 1级； 方式二、 在观看移动终端视频的人眼与移动终端屏幕之间的距离区间以等差的方 式增长 （如： 差值为 50mm)， 视频中音量的大小也以等差的方式增长 （如： 差值为 2 级）， 最小级可以预设为 1级。 例如： 0mm-50mm对应 1级， 50mm- 100mm对应 3级， 100mm- 150mm对应 5级。 下面根据图 2对上述优选实施方式做进一步的描述。 图 2根据本发明优选实施例的移动终端视频的呈现方法的流程图。 如图 2所示， 该流程可以包括以下处理步骤： 步骤 S202: 加载服务程序， 将该服务程序添加到开机启动任务项中， 在移动终端 开机后， 该服务程序被加载并在后台运行， 此程序相当于控制中心； 步骤 S204: 获取移动终端前台运行的视频播放器的当前状态； 如果播放器当前为 正在运行状态或者暂停状态， 则开启近感感应处理线程； 步骤 S206:监测是否有近感感应事件 /或者应用近感感应的相关事件发生；如果是， 则执行步骤 S208; 如果否， 则继续进行监测； 在优选实施例中， 近感感应事件可以通过移动终端感知近感传感器的输出信号进 行监测。 步骤 S208: 判断当前运行的播放器是否支持近感感应功能； 如果支持， 则继续执 行； 如果不支持， 则转到步骤 S226; 在优选实施例中， 图 3是根据本发明优选实施例的移动终端视频初始化设置界面 的示意图。 如图 3所示， 为了更好的控制近感感应功能， 增强用户体验， 在该优选实 施例中可以根据用户的需求设置人眼与屏幕之间的默认距离以及移动终端视频的初始 化音量， 并且在设置近感感应功能的同时， 可以对该功能进行必要的校准。 步骤 S210: 在处理近感感应线程中处理近感感应数据， 获得近感偏移位移以及方 向； 如果偏移位移未超出原距离区间， 则转到步骤 S206; 如果偏移位移超出原距离区 间， 则继续执行步骤 S212; 步骤 S212: 获取变化后的屏幕与人眼之间的距离相对于预设距离的偏移位移； 步骤 S214: 计算出当前屏幕与人眼之间的距离， 以调节字幕大以及音量大小； 步骤 S216: 开启视频处理线程， 该线程主要用于根据近感感应线程中得出的数据 执行进一步的操作； 步骤 S218: 获取同步的视频图像帧以及当前播放时刻等数据， 由此计算出字幕文 件中的当前播放位置； 步骤 S220: 从字幕文件中取出当前播放的字幕， 并在屏幕上输出成相应大小的字 幕， 同时返回步骤 S218继续执行； 步骤 S222: 从近感感应处理线程中获取音量大小， 设置成视频播放器的音量； 步骤 S224: 保存当前设置的字幕大小及音量大小， 同时返回步骤 S206继续执行
Γττί. ； 步骤 S226: 关闭视频处理线程； 步骤 S228: 结束近感感应监测。 在该优选实施例中， 通过无限循环一直监控前台视频播放器的运行状态， 并实现 根据检测到的近感感应数据来动态控制视频播放器的字幕和音量。 图 4是根据本发明实施例的移动终端视频的呈现装置的结构框图。 如图 4所示， 该移动终端视频的呈现装置主要包括： 获取模块 10， 设置为获取移动终端视频所在的 屏幕与观看移动终端视频的人眼之间的距离； 第一调节模块 20， 设置为根据获取到的 距离调节移动终端视频中字幕的大小，其中，字幕的大小与获取到的距离成递增关系。 采用如图 4所示的装置， 解决了相关技术中， 用户在移动终端上观看视频时， 移 动终端屏幕上的字幕无法随着用户与移动终端屏幕之间距离的改变而做出适应性调整 的问题， 实现了在用户观看移动终端视频的过程中， 移动终端可以根据屏幕与人眼之 间距离的实时变化， 动态确定适于观看视频的字幕和音量， 有效提高了用户的多媒体 体验。 优选地， 如图 5所示， 上述获取模块 10可以包括： 感应单元 100， 设置为感应获 取到的距离是否等于预设距离； 第一确定单元 102， 设置为在感应单元输出为否时， 确定获取到的距离相对于预设距离的偏移位移； 计算单元 104， 设置为采用偏移位移 和预设距离计算出获取到的距离。 优选地， 如图 5所示， 上述第一调节模块 20可以包括： 第二确定单元 200， 设置 为确定获取到的距离所在的预设距离区间对应的字幕大小； 第一调节单元 202， 设置 为将移动终端视频中字幕的大小调节至与预设距离区间对应的字幕大小。 优选地， 如图 5所示， 上述装置还可以包括： 第二调节模块 30， 设置为根据获取 到的距离调节移动终端视频中音量的大小， 其中， 音量的大小与获取到的距离成递增 关系。 优选地， 如图 5所示， 上述第二调节模块 30可以包括： 第三确定单元 300， 设置 为确定获取到的距离所在的预设距离区间对应的音量大小； 第二调节单元 302， 设置 为将移动终端视频中字幕的大小调节至与预设距离区间对应的音量大小。 上述各模块以及各单元相互之间优选的工作方式可以参见图 1至图 3的优选实施 例， 此处不再赘述。 图 6是根据本发明优选实施例的移动终端视频的呈现装置的示意图。如图 6所示， 服务程序被加载后， 可以通过无限循环和多线程技术一直监控视频播放器的状态以及 近感感应状态， 从而根据近感感应状态来动态改变视频播放时字幕的大小以及音量的 大小。 该服务程序还可以通过上述如图 3所示的设置页面设置初始的距离和音量的大 小， 用户可以灵活的配置自己喜好的距离和音量， 具有良好的实用性。 其中， 近感感 应事件监测模块（相当于上述感应单元）， 设置为在监测到近感感应事件或者应用近感 感应的相关事件后， 向近感感应处理模块发出指示； 近感感应设置模块， 设置为提供 近感感应功能的初始化设置， 如： 默认距离、 默认音量， 并保存至文件中； 近感感应 处理模块 （相当于上述第一确定单元、 计算单元、 第二确定单元以及第三确定单元）， 设置为处理接收到的近感感应数据， 判断是否需要对字幕和音量进行改变， 并且计算 出需要改变的大小等参数， 以供前台视频处理模块使用； 前台视频处理模块 （相当于 第一调节单元和第二调节单元），根据近感感应处理模块计算出的数据，动态调整同步 输出的字幕的大小， 以及播放音量大小的改变。 从以上的描述中， 可以看出， 上述实施例实现了如下技术效果 （需要说明的是这 些效果是某些优选实施例可以达到的效果）： 在观看视频的过程中，无需用户点击按键 或者触摸屏幕， 移动终端即可以根据人眼与屏幕之间距离的变化， 动态调整适于当前 视频使用的字幕的大小以及音量的大小， 从而有效提高了用户的体验。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以 将它们存储在存储装置中由计算装置来执行， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 或者将它们分别制作成各个集成电路模块， 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
