具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。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任意组合。
图1为本发明实施例中发送方法的流程图，如图1所示，所述发送方法应用于发送终端，包括：
步骤S11、基于接收终端的指令，调整发送终端采集的图像信息的分辨率；
在本实施例中，所述指令用于控制所述发送终端对其采集的图像信息的分辨率进行调整并将所述调整后的图像信息发送至所述接收终端。其中，所述指令的信息包括所述接收终端的屏幕的分辨率。
步骤S12、将所述调整后的图像信息发送至所述接收终端。
在本发明实施例中，所述基于接收终端的指令，调整发送终端采集的图像信息的分辨率包括：按照所述发送终端采集的图像信息的默认分辨率为基准划分的等级，对所述图像信息的分辨率进行调整。
其中，可以通过以下方式实现按照所述发送终端采集的图像信息的默认分辨率为基准划分的等级，对所述图像信息的分辨率进行调整：所述接收终端与所述发送终端建立连接后，所述发送终端将自身的分辨率划分等级发送至所述接收终端，所述接收终端根据接收的发送终端的所述分辨率等级和接收终端自身的分辨率参数向所述发送终端发送指令，指示所述发送终端按照发送终端自身采集的图像信息的分辨率，即默认分辨率为基准划分的等级分辨率，对所述图像分辨率进行调整并发送至所述接收终端。
下面以默认分辨率参数为1280*720的投影仪为发送终端举例说明。表1为发送终端分辨率等级划分表，如表1所示，将所述发送终端投影仪的分辨率等级以默认分辨率1280*720为基准划分为五个等级，其中可将默认分辨率作为第一等级，所述发送终端按照所述接收终端发送的指令对所述发送终端采集的图像信息的分辨率进行调整，并将调整后的图像信息发送至所述接收 终端，其中，指令用于指示发送终端按照哪个等级对图像信息的分辨率进行调整。
1280*720像素 第一等级
960*540像素 第二等级
800*450像素 第三等级
640*360像素 第四等级
480*270像素 第五等级
表1
可选地，在另一实施例中，所述基于接收终端的指令，调整发送终端采集的图像信息的分辨率包括：按照调整比例，对所述发送终端采集的所述图像信息的分辨率进行调整；其中，所述调整比例为所述发送终端的默认分辨率的水平方向像素数与垂直方向像素数的比值。
发送终端，例如微型投影仪，是以其默认分辨率进行图像信息采集的，即发送终端采集的图像信息的分辨率在水平方向像素数和垂直方向像素数的比率是确定的。为保证接收终端接收到的图像不因分辨率调整而变形，因此，发送终端在根据所述接收终端的分辨率对采集的所述图像信息进行调整时，也须按照所述发送终端在水平方向像素数和垂直方向像素数的比值作为调整比例，对采集的所述图像信息进行调整，并将调整后的图像信息发送至接收终端。
可以通过如下方式实现按照调整比例对所述发送终端采集的所述图像信息的分辨率进行调整；其中所述调整比例为所述发送终端的默认分辨率的水平方向像素数与垂直方向像素数的比值：
若所述接收终端屏幕的分辨率比所述发送终端采集的图像信息的默认分辨率高时，所述发送终端基于所述接收终端发送的指令对采集的所述图像信息的分辨率不进行调整，并直接发送至所述接收终端；
若所述接收终端屏幕的分辨率比所述发送终端采集的图像信息的默认分辨率低时，所述接收终端可向所述发送终端发送指令，控制所述发送终端对其采集的图像信息的分辨率进行调整，并将所述调整后的图像信息发送至所述接收终端。其中，所述指令控制所述发送终端调整所述图像信息的分辨率 的规则为：将所述接收终端分辨率的水平方向像素数与所述调整比例的比值作为调整后所述图像信息的垂直方向像素数，将所述接收终端屏幕分辨率的水平方向像素数作为调整后所述图像信息的水平方向的像素数。
下面以通过具体示例说明本发明实施例的技术方案。
在本实例中，接收终端为智能手机，发送终端为智能投影仪。智能手机的主屏分辨率有2K，1080p，720p，960*540像素，854*480像素，800*480像素，480*320像素，320*240像素，220*176像素。假设智能投影仪的分辨率是1280*720像素，智能投影仪的分辨率的水平方向像素数与垂直方向像素数的比例为16/9，即调整比例为16/9。
当远程控制该智能投影仪的智能手机的屏幕分辨率是960*540像素时，调整比例也是16/9，此时可将所述智能投影仪采集的图像信息的分辨率直接调整为960*540，发送至所述接智能手机。
当远程控制该智能投影仪的智能手机的屏幕分辨率为960*640像素时，此时对待发送的所述图像信息的调整指令为：智能手机水平像素960与所述调整比例16/9相比得到调整后所述图像信息的分辨率的垂直方向像素数为540，将所述接收终端手机设备屏幕分辨率水平方向上的像素作为所述图像调整后水平方向上的像素，即960。因此按照智能手机发送的指令，智能投影仪将采集的图像信息的分辨率从1280*720调整为960*540，然后将所述调整分辨率后的图像信息发送至智能手机。
如此，所述智能手机根据智能投影仪发送的所述图像信息对智能投影仪进行远程控制操作。
图2是本发明实施例中发送终端的示意图，如图2所示，本发明实施例的发送终端包括：调整模块11和发送模块12；其中，
所述调整模块11，设置为基于接收终端的指令，调整发送终端采集的图像信息的分辨率；
所述发送模块12，设置为将所述调整后的图像信息发送至所述接收终端。
可选地，所述调整模块是设置为：按照所述发送终端采集图像信息的默认分辨率为基准划分的等级对所述图像信息的分辨率进行调整；或者按照调 整比例对所述发送终端采集的所述图像信息的分辨率进行调整，其中所述调整比例为所述发送终端的默认分辨率的水平方向像素数与垂直方向像素数的比值。
图3是本发明实施例的接收方法的流程图，如图3所示，所述接收方法应用于接收终端，包括：
步骤S21、与发送终端建立连接并获取所述发送终端采集的图像信息的分辨率；
步骤S22、根据所述获取的所述发送终端采集的图像信息的分辨率与所述接收终端的配置参数，向所述发送终端发送指令；其中，所述配置参数包括所述接收终端屏幕的分辨率；所述指令用于控制所述发送终端对其采集的图像信息的分辨率进行调整并将所述调整后的图像信息发送至所述接收终端。
可选地，在另一本发明实施例中，所述接收方法还包括：接收所述发送终端发送的图像信息。
下面结合具体示例说明本发明实施例的技术方案。
在该示例中，接收终端为智能手机，发送终端为微型投影仪。智能手机通过Wi-Fi(Wireless-Fidelity)等近距离通信方式与微型投影仪建立连接；建立连接后，智能手机在建立连接的同时获取微型投影仪采集的图像信息的默认分辨率。智能手机根据获取到的投影仪采集的图像信息的分辨率和智能手机自身的配置参数，包括处理器运行参数、屏幕分辨率参数等，向微型投影仪发送指令。
若智能手机屏幕的分辨率小于微型投影仪采集的图像信息的分辨率，则智能手机向微型投影仪发送指令，用于控制微型投影对其采集的图像信息的分辨率调整至适应所述智能手机显示的分辨率，并将调整后的图像信息发送至智能手机。
在对智能手机和微型投影仪的分辨率进行判断分析后，智能手机也可根据接收的所述图像信息的流畅性来决定是否向所述微型投影仪再次发送指令，以调整图像信息的分辨率，从而保证智能手机接收所述图像信息的流畅 性。当智能手机接收所述图像信息流畅连贯时，智能手机即可根据所接受的所述图像信息对所述传输终端微型投影仪进行远程操作控制。
可选地，在本发明实施例中，可以通过以下至少一种方式实现向所述发送终端发送指令：
根据接收所述图像信息的接收速率向所述发送终端发送指令；
根据接收所述图像信息的接收网络的信号强度向所述发送终端发送指令。
在本发明实施例中，所述接收终端可以检测接收图像信息的接收网络的信号强度或接收速率，当检测到所述接收网络的信号强或接收速率高时，可向所述发送终端发送调高所述图像分辨率的指令；当检测到所述接收网络的信号弱或接收速率低时，则可向所述发送终端发送调低所述待发送图像分辨率的指令。
其中，所述接收网络的信号因不同的网络设备可能会存在不同的标定值。目前很多网络设备将网络信号大于-66dbm定义为信号强度非常好，网络速率能到达比较理想的状态；将信号小于-79dbm定义为没有信号。在以Wi-Fi方式建立连接时，接收网络的信号对接收速率的影响比较大，若Wi-Fi信号小于-71dbm，网络速率锐减。因此接收终端可根据实时检测接收网络的信号对所述发送终端发送指令。例如当所述接收终端实时检测到接收网络的信号锐减到小于-71dbm时，向所述发送终端发送调低分辨率指令；当所述接收终端实时检测到接收网络信号大于-66dbm时，向所述发送终端发送调高分辨率指令。此外，所述接收终端可实时检测每秒钟接收图像信息的数据帧量，例如当接收的数据帧量为每秒钟等于或大于20帧时，可向所述发送终端发送保持或调高分辨率的指令。
可选地，所述接收终端与所述发送终端建立连接的方式包括但不限于：
Wi-Fi连接、ZigBee(基于IEEE802.15.4标准的低功耗局域网协议)连接、蓝牙(Bluetooth)连接、NFC(Near Field Communication，近距离无线通讯技术)连接。
