具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
移动终端可以根据自身方向自动调整屏幕显示方式，如横屏显示或竖屏显示。例如，移动终端横屏显示时的截屏图片为图1所示，竖屏显示时的截屏图片为图2所示。通过图1和图2可知，横屏显示与竖屏显示时截屏图片的长宽比不同。然而，大多数的计算机的显示窗口是16:9的显示比例。若计算机收到图1和图2所示的截屏图片，在16:9的显示窗口中显示时，横屏时的截屏图片的显示效果与图1基本相同；竖屏时的截屏图片的显示效果参见图3所示。通过图3可知，截屏图片被明显缩小，清晰度较差。若希望清楚显示，还需要进行放大处理。本公开实施例中，移动终端除了传输截屏图片，还传输截屏图片的方向信息，增加了传输的信息量，为计算机侧的显示提供了参考信息。计算机可根据方向信息适应性显示截屏图片，提高显示效果。
图4是根据一示例性实施例示出的一种传输图像的方法的流程图，如图4所示，该方法可以由移动终端实现，包括以下步骤：
在步骤401中，接收计算机发送的IP连接请求。
在步骤402中，根据收到的所述IP连接请求获得所述计算机的IP地址。
在步骤403中，获取截屏图片及截屏图片的方向信息。
在步骤404中，通过IP层根据收到的所述IP地址将所述截屏图片和所述方向信息发送给所述计算机。
本实施例中移动终端除了获取和传输截屏图片，还获取和传输截屏图片的方向信息。目的是将方向信息提供给对端的计算机，以便计算机根据方向信息更好的显示截屏图片，解决因移动终端的横屏或竖屏所导致的图片显示效果不佳的问题。并且，移动终端通过一次接收IP连接请求便可获得计算机的IP地址，实现后续的截屏图片的传输，简化了IP连接过程，提高了效率。
移动终端与计算机可以通过USB(Universal Serial Bus，通用串行总线)连接或无线连接，无线连接包括：wifi(Wireless Fidelity，无线保真)连接、蓝牙连接和NFC(Near Field Communication，近场通信)连接等。相关技术中移动终端与计算机通过上述连续发送传输信息，上述连接发送均属于物理层连接，彼此兼容性较差。为了使截屏图片的传输适用于各种连接方式，本实施例中采用IP层通信，通过IP层传输截屏图片，可兼容各种物理连接方式。
本实施例中的移动终端可以是手机、平板计算机等可以自动旋转屏幕的电子设备。计算机可以是笔记本电脑、台式计算机和台式一体机等一般不自动旋转屏幕的电子设备。
在步骤403中，获取截屏图片的方向信息有多种实现方式，如方式A1-方式A3。
方式A1：移动终端可以用一个专门的状态标识来标记当前的屏幕方向，并将该状态标识存储在预设的存储位置。本实施例中可以将该状态标识作为截屏图片的方向信息。所以可以从本地预设的存储截屏图片的方向信息的存储位置读取出方向信息。
方式A2：如图1所示，横屏时截屏图片的长宽比是16:9，长度大于宽度。如图2所示，竖屏时截屏图片的长宽比是9:16，长度小于宽度。因此，可以通过截屏图片的长度大于宽度来确定截屏图片为横屏显示时的截屏图片，以及通过截屏图片的长度小于宽度来确定截屏图片为竖屏显示时的截屏图片。所以，可以根据所述截屏图片的长宽比确定截屏图片的方向信息。
方式A3：移动终端通过本地的方向感应器可获知自身发生旋转，并自动进行屏幕旋转，所以移动终端可通过本地的方向感应器确定当前的方向，并可根据方向感应器提供的方向信息确定当前是横屏还是竖屏。因此，可以根据本地方向感应器确定的方向信息确定截屏图片的方向信息。例如，参见图5和图6所示。移动终端的方向在[0,45]、[125,225]或[315,360]时，为横屏显示，确定截屏图片的方向信息为表示横屏的方向信息；移动终端的方向在(45,125)或(225,315)时，为竖屏显示，确定截屏图片的方向信息为表示竖屏的方向信息。
本实施例中的方向信息包括表示横屏的方向信息和表示竖屏的方向信息，可以有多种 表现形式。例如，用“0”作为表示横屏的方向信息，用“1”作为表示竖屏的方向信息。
在步骤403中，获取截屏图片的过程可以因应用场景不同而有不同的实现方式。如方式B1和方式B2。
方式B1：收到截屏和传输指令时，进行截屏处理，获得截屏图片。之后，发送获得的截屏图片。该方式可以适用于一次性的截屏图片的获取和传输。
方式B2：对本地的界面进行截屏操作，获得截屏图片；将获得的截屏图片存储到帧缓存器(Framebuffer)；从帧缓存器中获取截屏图片。该方式可以适用于实时的双屏同步。在收到同步指令后，连续进行截屏处理；每获得一张截屏图片，便将该截屏图片存储到帧缓存器；然后从帧缓存器中读取截屏图片并进行发送，这样可缓解截屏和发送不同步的问题。以及，每发送一张截屏图片，可将该截屏图片从帧缓存器中删除，以便继续存储新的截屏图片。
为了提高传输效率，可以对所述截屏图片进行压缩，获得压缩后的截屏图片；通过IP层将所述压缩后的截屏图片和所述方向信息发送给计算机。
在步骤401中，移动终端通过接收IP连接请求，相当于建立了IP连接，简化了建立IP连接的过程。为了便于截屏图片的传输，本实施例可采用会话协议进行传输。因此，所述IP连接请求为基于IP层的RTSP(Real Time Streaming Protocol，实时流传输协议)会话连接请求，RTSP会话连接请求包括用于截屏图片传输的UDP端口号。下面针对RTSP会话连接过程进行介绍。
移动终端处于RTSP服务的启动状态。以计算机发起连接为例，参见图7所示。计算机预先获得有移动终端的IP地址，例如通过USB连接和wifi扫描等方式获得移动终端的IP地址。
在步骤701中，计算机根据移动终端的IP地址向移动终端发送RTSP会话连接请求，其中RTSP会话连接请求包含计算机的IP地址和UDP端口号，UDP端口号用于截屏图片的传输。
在步骤702中，移动终端向计算机发送RTSP会话连接响应。通过RTSP会话连接响应与计算机进行各种参数的协商，相当于将响应过程与参数协商过程合并，进一步简化了连接过程。
在步骤703中，移动终端保存计算机的IP地址和UDP端口号，以便后续进行截屏图片的传输。
有了图7所示的连接过程后，在步骤404中，通过IP层的RTSP会话，向所述IP地址和UDP端口号的计算机发送所述截屏图片和所述方向信息。
移动终端与计算机建立连接后，可能会发生网络断开。网络断开可能有两种情况。情况1：异常断开；其原因可能有移动终端故障或计算机故障等。情况2：正常断开；例如移动终端向计算机发送断开消息或暂停消息，计算机收到断开消息或暂停消息后，进行断开网络的处理。
前面主要是以移动终端的角度介绍了传输截屏图片的过程，截屏图片的接收端为计算机，下面以计算机的角度介绍传输截屏图片的过程。
图8是根据一示例性实施例示出的一种传输图像的方法的流程图，如图8所示，该方法可以由计算机实现，包括以下步骤：
在步骤801中，根据本地存有的移动终端的IP地址，向移动终端发送IP连接请求。
在步骤802中，通过IP层接收移动终端发送的截屏图片和截屏图片的方向信息。
在步骤803中，根据所述方向信息显示所述截屏图片。
本实施例中计算机除了接收截屏图片以外，还接收了截屏图片的方向信息，增加了接收的信息量。并且，计算机可以根据收到的方向信息更好的显示截屏图片，提高显示效果。另外，计算机通过IP层接收截屏图片和方向信息，兼容各种物理连接，不受物理连接形式的限制。
在步骤803中，根据所述方向信息显示所述截屏图片，可以有多种实现方式，如方式C1和方式C2。
方式C1：计算机的显示屏一般为16:9的显示屏，因此显示窗口一般也为16:9。这样的显示窗口较适合显示横屏截图时的截屏图片。因此根据方向信息确定截屏图片是横向的截屏图片时，可直接显示截屏图片。根据方向信息确定截屏图片是竖向的截屏图片时，按照显示窗口的长度对截屏图片进行放大显示。
方式C2：计算机根据所述方向信息控制用于显示所述截屏图片的窗口的比例和尺寸，通过所述窗口显示所述截屏图片。方式C2中，显示窗口的比例和尺寸不固定，根据截屏图片的情况进行调整。例如，根据方向信息确定截屏图片是横向的截屏图片时，显示窗口为16:9的比例，显示窗口的尺寸按照截屏图片的分辨率调整。根据方向信息确定截屏图片是竖向的截屏图片时，显示窗口为9:16的比例，显示窗口的尺寸按照截屏图片的分辨率调整。
在步骤801中，计算机存有移动终端的IP地址。例如，计算机安装有“手机助手”的应用，通过该应用获得移动终端的IP地址，不需要寻址过程。计算机可直接通过存储的IP地址向移动终端发送IP连接请求。并且为了便于截屏图片的传输，所述IP连接请求为基于IP层的RTSP会话连接请求，RTSP会话连接请求包括用于截屏图片传输的UDP端口号。连接过程可参见前面的介绍，此处不再赘述。则，在步骤802中，通过IP层的RTSP会话，在所述UDP端口号上接收所述移动终端发送的截屏图片和截屏图片的方向信息。
通过以上介绍可知，传输截屏图片的多个环节都可能有多种实现方式，下面通过几个实施例来详细介绍实现过程。
图9是根据一示例性实施例示出的一种传输图像的方法的流程图，如图9所示，包括以下步骤：
在步骤901中，移动终端收到截屏和传输指令时，进行截屏处理，获得截屏图片。
在步骤902中，移动终端从本地预设的存储截屏图片的方向信息的存储位置读取出方向信息。
在步骤903中，移动终端通过IP层将截屏图片和方向信息发送给计算机。
在步骤904中，计算机通过IP层接收移动终端发送的截屏图片和截屏图片的方向信息。根据方向信息确定截屏图片是横向的截屏图片时，继续步骤905；根据方向信息确定截屏图片是竖向的截屏图片时，继续步骤906。
在步骤905中，计算机直接在显示窗口中显示截屏图片。
在步骤906中，计算机按照显示窗口的长度对截屏图片进行放大显示。
例如，移动终端传输的截屏图片参见图2所示，计算机放大后显示的截屏图片参见图10所示。放大后的截屏图片显示较清晰。
图11是根据一示例性实施例示出的一种传输图像的方法的流程图，如图11所示，包括以下步骤：
在步骤1101中，移动终端对本地的界面进行截屏操作，获得截屏图片。
在步骤1102中，移动终端将获得的截屏图片存储到帧缓存器。
在步骤1103中，移动终端从帧缓存器中获取截屏图片。
在步骤1104中，移动终端根据所述截屏图片的长宽比确定截屏图片的方向信息。
在步骤1105中，计算机通过IP层接收移动终端发送的截屏图片和截屏图片的方向信息。根据方向信息确定截屏图片是横向的截屏图片时，继续步骤1105；根据方向信息确定截屏图片是竖向的截屏图片时，继续步骤1106。
在步骤1106中，选择适合于横屏显示的显示窗口，并在显示窗口中显示截屏图片。例如，选择16:9的显示窗口，显示窗口的尺寸按照截屏图片的分辨率调整。
在步骤1107中，选择适合于竖屏显示的显示窗口，并在显示窗口中显示截屏图片。例如，选择9:16的显示窗口，显示窗口的尺寸按照截屏图片的分辨率调整。
本实施例中通过调整显示窗口的比例，使其适应截屏图片，所以移动终端截屏时的截屏图片的显示效果与计算机上的显示效果基本一致，显示效果较好，优于图3所示的显示效果。
