具体实施方式
以下结合附图对本发明的优选实施例进行详细说明，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
图1是本发明实施例提供的移动终端屏幕截图方法原理框图，如图1所示，步骤包括：
步骤S101：移动终端根据用户截图指令，对屏幕当前显示内容和屏幕当前未显示内容进行读取。
在步骤S101之前，需要预先设置用来启动屏幕截图功能的物理按键或滑屏图案，移动终端对所设置的物理按键或滑屏图案是否被触发进行检测，并当检测到所设置的物理按键或滑屏图案被触发时，生成用户截图指令。
移动终端包括前缓冲区和后缓冲区，在步骤S101中，移动终端从前/后缓冲区对屏幕当前显示内容进行读取，并从后/前缓冲区对屏幕当前未显示内容进行读取。
步骤S102：对所读取的屏幕当前显示内容和屏幕当前未显示内容进行合成，形成一张图片。
步骤S103：对所形成的图片进行屏幕截图，得到截图图片。
在步骤S103中，通过对所形成的图片进行缩放处理，将所述图片显示到屏幕上，形成预览界面；对用户在预览界面上选取的截屏区域进行裁剪，得到截图图片并保存。
进一步地，上述当前未显示内容是用来在当前显示内容之后显示的下一屏显示内容。也就是说，本实施例所提供的方法至少能够实现双屏截图，即执行一次截图动作，得到超过当前屏幕显示范围的两个屏幕内容的图片。
图2是本发明实施例提供的移动终端屏幕截图装置框图，如图2所示，包括：读取模块10、合成模块20和截图模块30。
读取模块10，配置为根据用户截图指令，对屏幕当前显示内容和屏幕 当前未显示内容进行读取。
合成模块20，配置为对所读取的屏幕当前显示内容和屏幕当前未显示内容进行合成，形成一张图片。
截图模块30，配置为对所形成的图片进行屏幕截图，得到截图图片。
进一步地，该装置还包括触发模块40，配置为根据用户操作生成用户截图指令。
具体地说，触发模块对预先设置的用来启动屏幕截图功能的物理按键或滑屏图案是否被触发进行检测，并当检测到所设置的物理按键或滑屏图案被用户触发时，生成用户截图指令。此时，读取模块10一次性读取移动终端的前后缓冲区和后缓冲区缓存，即从移动终端的前/后缓冲区对屏幕当前显示内容进行读取，从移动终端的后/前缓冲区对屏幕当前未显示内容进行读取。合成模块20对所读取的内容进行解析，并生成包含完整内容的一张图片。最后，截图模块30通过对所生成的图片进行缩放处理，将所述包含当前预览内容和当前未预览内容的图片显示到屏幕上，形成预览界面，并对用户在预览界面上选取的截屏区域进行裁剪，得到截图图片并保存。
其中，图1和图2提供的实施例中，合成得到的图片可以是由像素点构成的位图图片，例如可以是16色位图图片、256色位图图片、24位位图图片等等。
其中，当前未显示内容是用来在当前显示内容之后显示的下一屏显示内容，即图2提供的实施例至少能够实现双屏截图。
以双屏合成一张位图图片实现截图为例，在待截图界面，获取屏幕截图指令，读取帧缓冲区(Framebuffer)内两屏的像素数据，生成位图，实现双屏截图功能。其中，所述Framebuffer是指嵌入式系统中专门为图像处理单元(Graphic Processing Unit，GPU)所保留的一块连续的物理内存，在智能终端中，屏幕显示的图像数据(即像素数据)保存在Framebuffer中， LCD通过专门的总线从Framebuffer读取图像数据，显示到屏幕上。进一步地，根据Framebuffer的数量，可以分为单缓冲技术和双缓冲技术，目前智能终端系统主要采用双缓冲技术，也就是存在两个Framebuffer，包括前缓冲区(Front Buffer)和后缓冲区(Back Buffer)，当液晶显示器(Liquid Crystal Display，LCD)显示Front Buffer的内容时，中央处理器(Central Processing Unit，CPU)会向Back Buffer写入待显示的另外一张图片的像素数据。因此，对于双缓冲设备，Framebuffer中共保存了两张图片的像素数据。这样，在获取屏幕截图指令时，一次性读取Framebuffer中两张图片的像素数据，并生成一张位图，从而实现双屏截图功能。
图3是本发明实施例涉及的双缓冲技术示意图，如图3所示，在102中，屏幕(Screen)显示的是Front Buffer中的内容图像1；而此时，CPU会在后台向Back Buffer中写入图像2的数据。
在界面需要刷新时，终端进入104状态，Screen通过总线读取并显示Back Buffer中的内容图像2，同时，CPU会在后台向Front Buffer中写入图像3的数据。
以上即为双缓冲技术的基本原理，双缓冲技术提高了屏幕图像刷新的效率，在后台缓冲区同时保存了当前界面显示的图像数据和待显示的另外一幅图像的数据；
图4是本发明实施例提供的移动终端屏幕截图方法流程图，如图4所示，步骤包括：
步骤S202：终端接收屏幕截图指令，启动屏幕截图功能。
其中，所述的屏幕截图指令可以是系统或用户预设的物理热键组合键操作，比如同时按下组合键：音量+和音量-，也可以是预设的多点触控手势轨迹，比如用户在屏幕中执行预设图案的滑屏操作。
步骤S204：读取并解析帧缓冲区图像数据，生成位图。
以linux内核的移动终端为例，帧缓冲区被映射为设备节点文件/dev/fb0，可以通过类似普通文件的读取方式，打开并读取该文件的内容，具体的，该文件中包含了Front Buffer和Back Buffer的内容。之后，将读取得到的数据进行解析，并生成一个位图(Bitmap)，具体的，此处生成的位图的内容包含了两幅图片的数据，位图的尺寸相当于终端屏幕尺寸的两倍。
步骤S206：显示图片预览界面。
将步骤S204得到的位图进行缩小，把位图的所有内容完整的显示在终端屏幕上，形成预览界面；具体的，位图缩小的比例可以在40％至60％，例如可以是50％，以便于屏幕可以完整显示位图内容。
步骤S208：裁剪图片。
在预览界面，存在一个可以改变大小和位置的区域选择框，该选择框的形状可以是矩形或圆形等形状；用户可以拖动选择框非边框位置改变其在预览界面的位置；用户可以拖动选择框的边框，改变选择框的大小。
用户可以使用该选择框对预览的图片进行裁剪：在选择框内的图片内容将会被保留下来，选择框外的图片内容将会被舍弃；当选择框的大小占满整个屏幕时，预览界面的所有图片内容将会被保留。
S210：保存图片。
在用户裁剪完毕后，可以对图片进行保存，在终端的文件系统中生成最终的截图图片。具体的，用户可以通过点击预览界面内的保存按钮执行保存动作，或通过预设的物理按键执行保存动作。
图5是本发明实施例提供的移动终端屏幕截图装置结构示意图，如图5所示，移动终端包括：数据获取模块32、图像显示模块34和控制模块36，其中，数据获取模块32实现了图2实施例的读取模块10和合成模块20的功能，图像显示模块34和控制模块36实现了图2实施例的截图模块30的 功能。
数据获取模块32，配置为获取屏幕截图指令，读取帧缓冲区的像素数据，并生成位图；
图像显示模块34，配置为将生成的位图显示到终端屏幕上，例如以预览界面的形式显示。
控制模块36，配置为控制最终的图片截取区域和保存图片，即控制图片裁剪区域，并将图片裁剪区域内的内容保存为最终图片。
综上所述，本发明实施例具有以下技术效果：
本发明实施例利用双缓冲技术，实现了单次屏幕截图动作获取两屏图像数据的功能，增强了终端截屏功能，提高了用户体验。
本发明实施例提供的移动终端屏幕截图装置中的读取模块、合成模块、截图模块、触发模块等模块都可以通过移动终端中的处理器来实现；当然也可通过具体的逻辑电路实现；在具体实施例的过程中，处理器可以为中央处理器(CPU)、微处理器(MPU)、数字信号处理器(DSP)或现场可编程门阵列(FPGA)等。
需要说明的是，本发明实施例中，如果以软件功能模块的形式实现上述的移动终端屏幕截图方法，并作为独立的产品销售或使用时，也可以存储在一个计算机可读取存储介质中。基于这样的理解，本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机、服务器、或者网络设备等)执行本发明各个实施例所述方法的全部或部分。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read Only Memory)、磁碟或者光盘等各种可以存储程序代码的介质。这样，本发明实施例不限制于任何特定的硬件和软件结合。
相应地，本发明实施例再提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，该计算机可执行指令用于执行本发明各实施例中提供的移动终端屏幕截图方法。
尽管上文对本发明进行了详细说明，但是本发明不限于此，本技术领域技术人员可以根据本发明的原理进行各种修改。因此，凡按照本发明原理所作的修改，都应当理解为落入本发明的保护范围。
