图片共享方法及装置
技术领域
本发明涉及通信技术领域，尤其涉及一种图片共享方法及装置。
背景技术
随着全球电视数字化的日益推进，电视，电脑，pad或手机等设备可以通过家庭无线局域网非常方便地进行相互访问或控制。通过连接家庭无线路由器或wifi等，TV可以访问局域网内其它设备共享的多媒体内容，也可以访问internet上海量的多媒体资源。
在家庭局域网中，越来越多的用户喜欢把手机或Pad上的图片分享到TV端的大屏幕上供多人一起欣赏，用户先将手机上的图片缓存到预设存储位置中，然后将所述图片的地址信息，如远程访问链接（Uniform Resource Locator ，URL）共享到TV端，TV端通过访问所述URL下载并显示所述图片，在TV上看图片就像和手机上浏览一样方便。但是随着手机拍摄图片的像素越来越高，存储在手机上的图片文件也越来越大，当用户共享图片到TV端时，终端才将当前共享的图片缓存到预设存储位置中，而当图片较大或者是网速较慢时，会出现用户在手机端切换为另一张图片时，TV端还没显示切换的图片，而是显示缓冲提示或者还是显示前一张图片，显然共享图片的速度较慢。
发明内容
本发明的主要目的在于提出一种图片共享方法及装置，旨在解决图片共享过程中，共享速度较慢的技术问题。
为实现上述目的，本发明提供的一种图片共享方法，所述图片共享方法包括以下步骤：
在检测到图片共享指令时，控制终端进入图片共享状态，并显示与所述图片共享指令对应的第三图片；
基于所述图片共享指令压缩所述第三图片以及与所述第三图片相邻的第四图片和第五图片，将压缩后的三张图片放入缓存中；
将缓存中所述第三图片的压缩文件对应的第三地址信息发送至预设的显示终端，以供所述显示终端基于所述第三地址信息获取所述压缩文件并显示；
在终端处于图片共享状态，且接收到图片切换指令时，显示与所述图片切换指令对应的第一图片；
将缓存中与所述第一图片的压缩文件对应的第一地址信息发送至预设的显示终端，以供所述显示终端基于所述第一地址信息获取所述压缩文件并显示，同时，将与所述第一图片的原文件对应的第二地址信息发送给所述显示终端，以供所述显示终端在接收到第一图片显示指令时，基于所述第二地址信息获取所述原文件并显示；
基于所述图片切换指令压缩与所述第一图片相邻的第二图片，将压缩后的第二图片放入缓存中。
优选地，所述在检测到图片共享指令时，控制终端进入图片共享状态，并显示与所述图片共享指令对应的第三图片的步骤之前，所述图片共享方法包括：

优选地，所述图片共享方法还包括：
在图片共享过程中，删除所述缓存中预设数量的图片，其中，删除的图片的存储时间早于保留的图片的存储时间。
此外，为实现上述目的，本发明还提出一种图片共享方法，所述图片共享方法包括以下步骤：
在终端处于图片共享状态，且接收到图片切换指令时，显示与所述图片切换指令对应的第一图片；

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种图片共享方法。
参照图1，图1为本发明图片共享方法第一实施例的流程示意图。
本实施例提出一种图片共享方法，所述图片共享方法包括：
步骤S10，在终端处于图片共享状态，且接收到图片切换指令时，显示与所述图片切换指令对应的第一图片；
在本实施例中，所述步骤S10之前，包括以下步骤：在检测到图片共享指令时终端进入图片共享状态，并且显示所述图片共享指令对应的第三图片，然后基于所述图片共享指令压缩所述第三图片以及所述第三图片相邻的第四图片和第五图片，最后将压缩后的三张图片放入缓存中，也就是说在图片在开始共享时，将第一张共享的图片作为第三图片，然后压缩所述第三图片以及所述第三图片相邻的第四图片和第五图片，并将压缩的各张图片对应的压缩文件放入缓存中，实现了在图片切换过程中，不论是将所述第三图片切换为第四图片，或者是将所述第三图片切换为第五图片，都已经将所述第三图片的压缩文件放入缓存中，可以直接将所述第三图片对应的压缩文件的地址信息发送至预设显示终端，而不用等到切换到所述第三图片时，才对第三图片进行压缩缓存。在第三图片切换为第四图片或第五图片时，此时，所述第四图片或第五图片作为所述图片切换指令对应的第一图片。
在本实施例中，所述图片切换指令的触发方式包括：a、人为触发，即当用户将显示界面显示的上一张图片滑动到当前图片时，触发图片共享指令。b、定时触发，即在图片共享状态下检测到图片定时切换指令时，触发图片切换指令，所述图片定时切换指令事先根据具体需要设置，如设置图片共享状态下的图片定时切换时间为5S，则在上一张图片显示的时间达到5S时，触发图片切换指令，并切换为下一张图片。
步骤S20，将缓存与中所述第一图片的压缩文件对应的第一地址信息发送至预设的显示终端，以供所述显示终端基于所述第一地址信息获取所述压缩文件并显示；
在本实施例中，接收到切换指令时在显示界面显示第一图片，根据上述实施例可知，所述第一图片对应的压缩文件已经放入缓存了，则在切换为所述第一图片时，可直接获取缓存中所述第一图片的压缩文件对应的第一地址信息，并将所述第一地址信息发送至预设的显示终端，以供所述显示终端基于所述第一地址信息获取所述压缩文件并显示。可以理解的是，本实施例中图片共享场景应用于多屏互动场景中，即基于DLNA（Digital Living Network Alliance，数字生活网络联盟）协议实现，首先，显示终端与终端建立连接关系，优选所述终端为手机，所述显示终端为电视机，建立所述连接关系后，所述终端发送压缩后的第一图片对应的URL给所述显示终端，显示终端访问所述URL以登录到所述HTTP服务器，最后，所述显示终端加载所述压缩后的第一图片并显示。
进一步地，为提高图片共享的清晰度，将缓存中所述第一图片的压缩文件对应的第一地址信息发送至预设的显示终端的同时，将与所述第一图片的原文件对应的第二地址信息发送给所述显示终端，以供所述显示终端在接收到第一图片显示指令时，基于所述第二地址信息获取所述原文件并显示。也就是说不仅可以将压缩后的各个图片放入缓存中，还可将压缩前的各个图片也放入缓存中，即实现了缓存中同时存储同一张图片压缩前和压缩后的两个状态，并且，发送压缩后的第一图片对应的地址信息和压缩前的第一图片对应的地址信息至显示终端，以供所述显示终端先访问压缩后的地址信息再访问压缩前的地址信息，即先加载显示压缩后的第一图片，并在加载完所述压缩后的第一图片接着加载所述压缩前的第一图片，实现了用户在查看图片时，先查看压缩后的图片，若此时用户还未切换到下一张图片，所述显示终端还可显示压缩前的同一张图片，即压缩后的图片下载完后直接无缝替换压缩前的图片显示，这样对于用户来说既可以快速看到图片，又不必忍受压缩带来的画质损失，既满足了用户查看图片的速度，又提高了图片显示的清晰度。
步骤S30，基于所述图片切换指令压缩与所述第一图片相邻的第二图片，将压缩后的第二图片放入缓存中。
基于所述图片切换指令，压缩所述第一图片相邻的第二图片，可以理解的是，在图片共享过程中，若是按照一定的顺序切换图片，如持续向一个方向切换图片时，所述第一图片相邻的图片中已经有一张是已经压缩的图片，如图片的上一张图片是已经压缩过的了，则优选在所述第一图片切换为当前图片时，仅仅压缩所述第一图片相邻且还未压缩的第二图片即可，即压缩所述图片相邻的下一张图片，最后，将压缩后的第二图片也放入所述缓存中。
本实施例提出的图片共享方法，在终端处于图片共享状态且接收到图片切换指令时，先显示与所述图片切换指令对应的第一图片，然后压缩所述第一图片相邻的第二图片，并将压缩后的第二图片放入缓存中，最后将缓存中与所述第一图片的压缩文件对应的第一地址信息发送至预设的显示终端，以供所述显示终端基于所述第一地址信息获取所述压缩文件并显示，而不是每次在共享图片时，才将所述图片放入缓存中，本方案在显示当前图片时，就将缓存中所述当前图片的压缩文件对应的地址信息发送给显示终端，并压缩所述当前图片相邻的图片，实现了将当前图片进行共享时，直接将当前图片在缓存中对应的地址信息发送给显示终端，提高了图片的共享速度。
进一步地，为了提高图片共享的灵活性，基于第一实施例提出本发明图片共享方法第二实施例，在本实施例中，参照图2，所述步骤S10之前，所述图片共享方法包括：
步骤S40，在检测到图片共享指令时，控制终端进入图片共享状态，并显示与所述图片共享指令对应的第三图片；
步骤S50，基于所述图片共享指令压缩所述第三图片以及与所述第三图片相邻的第四图片和第五图片，将压缩后的三张图片放入缓存中。
步骤S60，将缓存中所述第三图片的压缩文件对应的第三地址信息发送至预设的显示终端，以供所述显示终端基于所述第三地址信息获取所述压缩文件并显示。
在本实施例中，所述图片共享指令的触发方式包括：a、在检测到用户基于所述预设的第三图片所在界面输入的触摸操作时，触发图片的共享指令，即检测到基于预设图片对应区域输入的长按指令时如按压所述图片的时间达到预设时间段如5秒时，触发图片的共享指令；或者在检测到基于预设图片对应区域输入的滑动触摸操作时，触发图片的共享指令。b、在检测到所述第三图片的定时共享指令时，触发图片共享指令，如事先设置所述第三图片的定时共享模式，在所述定时的时间到达时，触发图片共享指令。
在本实施例中，先基于所述图片共享指令压缩所述第三图片以及所述第三图片相邻的第四图片和第五图片，压缩所述第三图片、第四图片和第五图片后，将压缩后的三张图片放入缓存中，所述缓存可为所述终端预设的存储位置，本实施例中，优选终端为预设服务器，则相应的所述缓存为所述服务器中预设的根目录，所述服务器为HTTP（HTTP Hypertext Transfer Protocol，超文本传送协议）服务器，所述HTTP服务器中包含根（ROOT）目录，所述根目录用于存储压缩后的各个图片，即压缩后的图片缓存在所述服务器中的所述根目录中，并且在图片缓存到所述根目录时，根据缓存的图片生成所述缓存的图片对应的地址信息，如URL（Uniform Resource Locator，统一资源定位符），所述URL也可以理解为远程访问链接。
进一步地，为了提高图片共享的灵活性，基于第一实施例提出本发明图片共享方法第三实施例，在本实施例中，所述图片共享方法还包括：
在图片共享过程中，删除所述缓存中预设数量的图片，其中，删除的图片的存储时间早于保留的图片的存储时间。
在本实施例中，为了减小缓存中被占用的空间，优选在图片共享过程中，删除所述缓存中预设数量的图片，所述预设数量可根据具体的情况而定，本发明实施例中，优选删除所述缓存中预设数量的图片的方式为：在所述缓存中存储的图片数量达到预设阈值时，如3张时，此时若有第4张图片放入所述缓存中，则优选将所述4张图片中存储时间最早的一张图片进行删除，保证在图片共享过程中，所述缓存中始终存储低于或等于3张数量的图片。
本发明进一步提供一种图片共享装置。
参照图3，图3为本发明图片共享装置第一实施例的功能模块示意图。
需要强调的是，对本领域的技术人员来说，图3所示功能模块图仅仅是一个较佳实施例的示例图，本领域的技术人员围绕图3所示的图片共享装置的功能模块，可轻易进行新的功能模块的补充；各功能模块的名称是自定义名称，仅用于辅助理解该图片共享装置的各个程序功能块，不用于限定本发明的技术方案，本发明技术方案的核心是，各自定义名称的功能模块所要达成的功能。
本实施例提出的图片共享装置优选运行于被控终端（如智能手机以及电脑）中。
