具体实施例
为使本发明部分实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本发明各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本发明的第一实施例涉及一种电视控制方法，应用于包含图像采集模块、图像处理模块以及电视播放模块的电视控制系统。本实施例的电视控制方法的具体流程如图1所示。
步骤101：以预设周期定时采集可检测范围内的多幅图像。
其中，可检测范围内的图像是指以电视控制系统所在位置为拍摄位置，朝向电视播放方向拍摄的图像；即观看电视的用户所在区域的图像。
于本实施例中，图像处理模块内储存有预设周期；图像采集模块例如为摄像头，其在图像处理模块的控制下，以预设周期定时采集可检测范围内的多幅图像。预设周期例如为1.5分钟，即每隔1.5分钟采集一幅图像。在执行一次完整的电视控制方法中所采集的图像数目也可以根据需要设定；例如，采集的图像数目可以为20幅，其中，1.5分钟*20＝30分钟，即表示以30分钟为最小时长来判断是否久坐。然而，本实施例对预设周期以及采集的图像数目(判断是否久坐的最小时长，相当于下文提及的预设拍摄时长)不作任何限制，本领域技术人员可以根据实际需要设定。
另外，于其他实施例中，图像采集模块也可以为摄像头与微控制器的组合；此时预设周期可以储存于图像采集模块的微控制器中，摄像头直接受微控制器控制采集图像。
另外，上面所述的图像采集模块是定时采集图像(即通过定时拍照获取)；然不限于此，还可以通过录制视频图像的方式获取多幅图像。具体而言，在步骤101之前还可以包含如下步骤：图像采集模块获取预设拍摄时长内的可检测范围内的视频图像。此时步骤101实际上为：图像采集模块以预设周期从视频图像中定时采集多幅图像；即，从录制的视频图像中以预设周期截取多幅图像。其中，预设拍摄时长例如为30分钟，即表示以30分钟为判断是否久坐的最小时长；然不限于此，预设拍摄时长可以设定为用户自己认为的久坐状态的时长。
步骤102：判断电视播放模块是否处于播放状态。若是，进入步骤103；若否，进入步骤107。
即，图像处理模块会定时询问电视播放模块的状态，以便根据电视播放模块所处的不同状态采用不同的监测方法。或者，也可以由电视播放模块定 时主动向图像处理模块汇报其状态。
步骤103：判断各幅图像是否均包含用户的身体轮廓图像。若是，进入步骤104；若否，进入步骤105。
若电视播放模块处于播放状态，则图像处理模块会对各幅图像进行图像分析，判断各幅图像中是否均包含用户的身体轮廓图像。若各幅图像中均包含用户的身体轮廓图像，表示用户在该采集图像的时间段内(判断是否久坐的最小时长)一直在电视的观看区域。
步骤104：根据各身体轮廓图像的相对位置变化判断用户是否处于久坐状态。若是，进入步骤109；否则结束。
其中，步骤104可以有多种实现方式，本实施例中列举以下两种：
第一种实现方式：首先，图像处理模块根据相邻身体轮廓图像在相邻两幅图像中的相对位置，计算相邻身体轮廓图像的位置变化量；其次，图像处理模块判断相邻身体轮廓图像的位置变化量是否小于或等于预设变化量；若是，则图像处理模块判定用户处于久坐状态。
具体而言，多幅图像按照采集顺序依次排列；图像处理模块获取多幅图像中的相邻两幅图像中的两个身体轮廓图像，并分别计算两个身体轮廓图像在所述相邻两幅图像中的相对位置；根据两个身体轮廓图像的相对位置计算该两个身体轮廓图像的位置变化量。其中，相对位置可以通过选取参考点来计算；例如，以身体轮廓图像的中心点与其所在那幅图像的中心点为参考点计算身体轮廓图像的相对位置(例如以两个中心点的矢量差表示用户的身体轮廓图像相对于采集的图像的中心点的偏移)；此时，相邻身体轮廓图像的位置变化量为相邻身体轮廓图像的相对位置之差。
当相邻身体轮廓图像的位置变化量小于或等于预设变化量时，默认为用户位置没有发生变化。图像处理模块对所述多幅图像中的多组相邻图像的身体轮廓图像进行依次比较，若各相邻图像中的两个身体轮廓图像的位置均被 默认为没有发生变化，则表示在该采集图像的时间段内用户的位置没有发生变化，因此认定用户处于久坐状态。若在依次比较过程中，判断出存在一组相邻图像中的两个身体轮廓图像的位置发生变化，则认为用户位置发生变化；此时，不再进行后续判断，即认为该采集图像的时间段内用户并非处于久坐状态。
需要说明的是，这里的预设变化量可以根据实际情况设定；例如预设变化量可以设定为用户的最小移动幅度。
第二种实现方式：首先图像处理模块根据各身体轮廓图像在各幅图像中的相对位置，计算任意两幅图像中的身体轮廓图像的位置变化量；其次，图像处理模块判断任意两幅图像中的身体轮廓图像的位置变化量是否均小于或等于预设变化量；若是，图像处理模块判定用户处于久坐状态。
具体而言，图像处理模块分别计算采集的各身体轮廓图像在各幅图像中的相对位置；并计算任意两幅图像中的身体轮廓图像的位置变化量。其中，这里的任意两幅图像包含采集的多幅图像中两幅图像的两两组合的所有情况。本方式中关于各身体轮廓图像在各幅图像中的相对位置的计算方式、两幅图像中的身体轮廓图像的位置变化量的计算方式、以及根据位置变化量判断用户是否处于久坐状态的判断方式，均与第一种实现方式中相同，此处不再赘述。
由上分析可知，第一种实现方式是依序对相邻两幅图像中的身体轮廓图像的位置变化量进行判断，当判断出存在一组相邻两幅图像中的身体轮廓图像的位置没有发生变化时即可停止后续判断，在一定程度上节省了处理时间，降低了处理功耗。而第二种实现方式需要判断任意两幅图像中的身体轮廓图像的位置变化量，相较于第一种实现方式而言，判断更加全面，可以避免遗漏用户缓慢移动的情况(即在每个预设周期内的移动幅度小于预设变化量，而多个预设周期内的整体移动幅度大于预设变化量)。
步骤105：判断各幅图像是否均未包含用户的身体轮廓图像。若是，进入步骤106；否则结束。
若电视播放模块均未包含用户的身体轮廓图像，表示用户在该采集图像的时间段内始终不在电视的观看区域；即表示用户已离开(此时进入步骤106，即切换至待机状态)。
需要说明的是，结合步骤103与步骤105的判断内容，当步骤105的判断结果为否时，表示采集的多幅图像中，有一部分图像包含用户的身体轮廓图像，而另一部分图像未包含用户的身体轮廓图像；即表示在该采集图像的时间段内，用户有一部分时间在电视的观看区域，且有一部分时间离开过电视的观看区域。这种情况下，说明在该采集图像的时间段内用户的位置发生过改变(不处于久坐状态，也不处于睡眠状态)，因此电视控制系统默认为用户看电视时处于相对健康的行为状态，不需要作出任何提醒。
步骤106：从播放状态切换至待机状态。
即，电视播放模块进入低功耗的工作模式；从而可以节能能耗。
较佳的，在电视播放模块进入低功耗的工作模式后，图像采集模块将预设周期增加预设时长。采集图像的预设周期变长，即采集图像的频率降低；换句话说，在预设的采集图像的时间段(即判断是否为久坐状态的最小时长)内采集的图像数目减少，从而可以减轻图像处理模块的处理负担，并进一步降低待机状态的功耗。
步骤107：检测多幅图像中是否存在预设触发信号。若是，则进入步骤108；否则结束。
其中，预设触发信号可以是手势轨迹或面部表情(包括眨眼等面部动作)。本领域技术人员应当知晓，预设触发信号可以通过现有的图像分析技术识别出来，此处不再赘述。
步骤108：从待机状态切换至播放状态。
其中，电视播放模块从待机状态切换至播放状态后，播放画面可以自行设定，例如可以为上次播放画面或者一个预设画面。
步骤109：产生久坐提示信息。
其中，久坐提示信息可以为视频画面提示，即在电视画面上播放预先储存的提示短片，提示短片内可包含头部运动、肩部运动、起立活动等示范性动作(也可以是预设的屏保图案)；或者，久坐提示信息可以为字幕提示，即在电视画面的预设区域显示文字提示信息；或者，久坐提示信息也可以为语音提示，即通过喇叭播放提示语音。本实施例对久坐提示信息的具体形式不作任何限定。
本发明的第二实施例涉及一种电视控制方法。第二实施例是在第一实施例基础上的改进，主要改进之处在于：在本实施例中，还可以根据身体轮廓图像判断用户是否处于睡眠状态，且当用户处于睡眠状态时电视播放模块进入待机状态；从而可以避免不必要的能耗。
本实施例的电视控制方法具体流程如图2所示；其中，步骤201～203、步骤206～211与第一实施例方式中的步骤101～103、步骤104～109对应相同；本实施例中新增了步骤204与步骤205，具体说明如下。
步骤204：根据各身体轮廓图像分析用户的眨眼频率。
其中，本领域技术人员应当知晓，利用现有的眼球追踪技术或者根据眼皮的开合变化，即可根据各身体轮廓图像分析出用户的眨眼频率，此处不再赘述。
步骤205：根据眨眼频率判断用户是否处于睡眠状态。若是，进入步骤208；若否，进入步骤206。
其中，图像处理模块中预设有眨眼频率阈值，该眨眼频率阈值表示用户 处于清醒状态的最低眨眼频率，该眨眼频率阈值可由用户自己设定或者根据经验值出场预置。当从多幅图像中分析出的眨眼频率小于该眨眼频率阈值时，表示用户处于睡眠状态。
本发明的第三实施例涉及一种电视控制方法。第三实施例是在第二实施例基础上的改进，主要改进之处在于：在本实施例中，还可以根据身体轮廓图像判断用户是否处于近距离观看状态，且当用户处于近距离观看状态时进行提醒；从而，避免用户因在不知不觉中长时间的近距离观看而造成对眼睛的伤害。
本实施例的电视控制方法具体流程如图3所示；其中，步骤301～311与第二实施例方式中的步骤201～211对应相同；本实施例中新增了步骤312与步骤313，具体说明如下。
步骤312：根据各身体轮廓图像在各幅图像中的相对比例判断用户是否处于近距离观看状态。若是，则进入步骤313；否则结束。
具体而言，图像处理模块计算各身体轮廓图像在各幅图像中所占的面积比例；面积比例越大，表示观看距离越近。图像处理模块内预设有面积比例阈值，面积比例阈值可以由用户自行设定，表征用户认为的近距离观看的界限。当根据采集的图像计算出的面积比例大于或等于该面积比例阈值时，表示用户处于近距离观看状态。
步骤313：产生近距离观看提示信息。
其中，近距离观看提示信息可以为视频画面提示，即在电视画面上播放预先储存的提示短片；或者，近距离观看提示信息可以为字幕提示，即在电视画面的预设区域显示文字提示信息；或者，近距离观看提示信息也可以为语音提示，即通过喇叭播放提示语音。本实施例对近距离观看提示信息的具体形式不作任何限定。
需要说明的是，本实施例实际上也可以是在第一实施例上的改进，即将 本实施例中的步骤312、步骤313加入到第一实施例中的步骤109之后；本领域技术人员应当能够理解，此处不再赘述。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包含相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本发明第四实施例涉及一种电视控制系统，应用于第一、或第二、或第三实施例的电视控制方法。如图4所示，电视控制系统包含：图像采集模块、图像处理模块以及电视播放模块。
图像采集模块用于以预设周期定时采集可检测范围内的多幅图像；图像处理模块用于判断电视播放模块是否处于播放状态；
图像处理模块还用于在电视播放模块处于播放状态时，判断各幅图像是否均包含用户的身体轮廓图像；
图像处理模块还用于在各幅图像均包含用户的身体轮廓图像时，根据各身体轮廓图像的相对位置变化判断用户是否处于久坐状态
电视播放模块还用于在用户处于久坐状态时，产生久坐提示信息。
较佳的，所述电视播放模块还用于在各幅图像均未包含身体轮廓图像时，从所述播放状态切换至待机状态。
较佳的，所述图像处理模块还用于判断所述电视播放模块是否处于待机状态，并在所述电视播放模块处于待机状态时，检测所述多幅图像中是否存在预设触发信号；所述电视播放模块还用于在所述多幅图像中存在预设的播放触发信号时，从所述待机状态切换至所述播放状态。
以上所述的电视控制系统与第一实施例所述的电视控制方法相对应。
进一步的，所述图像处理模块还用于在各幅图像均包含用户的身体轮廓图像，且在根据各身体轮廓图像在的相对位置变化判断所述用户是否处于久坐状态之前，根据各身体轮廓图像分析所述用户的眨眼频率，并根据所述眨眼频率判断所述用户是否处于睡眠状态；所述电视播放模块还用于在所述用户处于睡眠状态时，从所述播放状态切换至待机状态。
以上所述的电视控制系统与第二实施例所述的电视控制方法相对应。
