 本发明的最佳实施方式
本发明提供一种大尺寸照片加载的方法及系统，为使本发明的目的、技术方案及效果更加清楚、明确，以下对本发明进一步详细说明。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。
请参阅图1，图1为本发明一种大尺寸照片加载的方法较佳实施例的流程图，如图所示，其包括步骤：
S1、移动终端加载大尺寸照片时，将所述大尺寸照片按预设尺寸分割成多个子照片；
S2、依据用户对移动终端触摸屏的拖动操作方向，将下一子照片移动至当前子照片的位置并进行实时显示。
在本实施例中，针对按照拍摄尺寸显示的大尺寸照片，将大尺寸照片分割成多个子照片，移动终端按照用户的操作指令，每次只需加载分割得到的某个子照片，即加载过程只需占用相应子照片所对应的内存，与加载整张照片的方式相比，内存占用量显著降低，在不影响移动终端运行速度的前提下，轻松实现对大尺寸照片的加载、显示及查看等操作。
本发明所述的移动终端，可以是手机、平板电脑等可以显示照片的便携式电子设备。
所述的大尺寸照片一般是指拍摄尺寸较大或分辨率较高，在加载和显示过程中需要占用较大内存空间的照片。进一步的，对大尺寸照片进行定义，其可以是尺寸大小超过系统中默认的尺寸阈值（例如1000×1000像素）的照片；还可以是，移动终端通过检测当前可用内存空间的大小，根据当前可用内存空间的大小来实时调整尺寸阈值，当当前可用内存空间小于第一内存阈值（如总内存空间的1/3）时，则更新所述尺寸阈值为500×500像素，那么当某个大尺寸照片大于500×500像素，则判定为大尺寸照片，否则不判定为大尺寸照片。当当前可用内存空间大于第二内存阈值（如总内存空间的2/3）时，则更新所述尺寸阈值为1500×1500像素，那么当某个大尺寸照片大于1500×1500像素，则判定为大尺寸照片，否则不判定为大尺寸照片。而当当前可用内存空间的大小处于第一内存阈值与第二内存阈值之间时，则还是按照系统默认的尺寸阈值进行判定，例如还是按照尺寸阈值为1000×1000像素来判定，当某个大尺寸照片大于1000×1000像素，则判定为大尺寸照片，否则不判定为大尺寸照片。总之，所述大尺寸照片的尺寸可以是根据某个固定的尺寸阈值来判定，也可以是根据移动终端当前的可用内存情况实时判断（即尺寸阈值是不断更新的）的，这样可以方便用户根据移动终端当前内存情况进行大尺寸照片的设定，保证移动终端运行速度不受影响的前提下，顺利实现用户对大尺寸照片的加载和显示等操作。
进一步，如图2所示，所述步骤S1具体包括：
S11、获取待加载的大尺寸照片的尺寸；
S12、判断所述大尺寸照片的尺寸是否大于尺寸阈值；
S13、当所述大尺寸照片的尺寸超过尺寸阈值时，则对所述大尺寸照片进行分割。
在移动终端检测到用户加载照片的指令后，获取待加载大尺寸照片的尺寸，根据移动终端当前状态下的尺寸阈值进行判断，当待加载照片尺寸大于尺寸阈值时，则判定为符合要求的大尺寸照片，将该大尺寸照片分割成若干块符合预设尺寸的子照片；当待加载照片尺寸不大于尺寸阈值时，则判定该大尺寸照片的尺寸较小，将其整体加载后不会对移动终端的运行内存造成大影响，因此不对其进行分割，直接将照片整体加载到内存中。
针对分割大尺寸照片得到的子照片的尺寸，可以是用户根据个人习惯和喜好预先设定的（如50×50像素）；更优选地，设置子照片的大小与移动终端触摸屏的尺寸相同，设置方法可以是用户输入移动终端的触摸屏尺寸，此处更优选移动终端检测自身的触摸屏大小，将大尺寸照片分割成与移动终端触摸屏尺寸相同的若干子照片，本发明以后者为例进行说明。设置子照片的尺寸与移动终端触摸屏的尺寸相同，每次只有与子照片尺寸相同的显示内容显示在移动终端的屏幕上，方便后续对子照片进行拖动、查看等操作。
进一步，所述步骤S13还包括：
按照各子照片在所述大尺寸照片中所处的位置，对各子照片依次采用二维矩阵的形式进行编号。
为方便后续对子照片的移动操作和查看，将大尺寸按照预设尺寸分割后，通过二维矩阵对其进行编号，所述编号包括两个成员，命名为横向成员和纵向成员，横向成员用来指定子照片所在行，纵向成员用来指定子照片所在列，如图3所示，即将大尺寸照片分割成xm×ym个子照片，然后按各子照片在大尺寸照片中的位置用二维矩阵进行编号处理，如一子照片在大尺寸照片中位于第i行第j列，则该子照片的编号为[i，j]。
作为本发明更优选的实施例，较佳的，所述步骤S13之后还包括：
在分割后，先加载并显示处于大尺寸照片中心位置的子照片。这是因为拍照时，主要拍摄对象一般位于照片的中心处，并且从大尺寸照片的中心位置可以通过拖动触摸屏操作方便的查看不同位置的子照片，因此，选择处于中心位置的子照片为大尺寸照片的初始显示对象较为合适。当然，用户可以根据个人拍照习惯设置初始显示对象为某一位置的子照片，例如左上角的子照片或者右上角的子照片。
进一步，以大尺寸照片的中心位置为基准进行分割，按照预设尺寸的宽度向大尺寸照片上下两侧扩展，按照预设尺寸的长度向大尺寸照片左右两侧扩展，完成对大尺寸照片的分割，并对其按照二维矩阵方式进行编号。
在步骤S2中，当用户向某一方向拖动移动终端的触摸屏，随着当前子照片逐渐从移动终端的触摸屏上消失，下一子照片逐渐显示在移动终端的触摸屏上，用户可以通过对移动终端触摸屏不同方向的拖动，使得相邻的其他子照片替代当前子照片显示在移动终端的触摸屏上。在该过程中，移动终端通过判断用户拖动触摸屏的加速度大小是否超过预设的加速度阈值，或者判断用户拖动触摸屏的位移大小是否超过预设的位移阈值，当上述两个条件任一满足时，则将当前触摸屏上显示的子照片替换为下一相邻子照片，当否时，触摸屏上仍显示当前子照片；还可以是，当移动终端检测到用户拖动触摸屏时，判断用户拖动触摸屏的加速度大小是否超过预设的加速度阈值，并且判断用户拖动触摸屏的位移大小是否超过预设的位移阈值，当上述两个条件均满足时，则将当前触摸屏上显示的子照片替换为下一相邻子照片，当任一条件不满足时，触摸屏上仍显示当前子照片，这样，移动终端就能有效区分用户对屏幕拖动的原因是需要切换当前子照片，还是由于误操作所致，能够有效避免误操作过程中加载照片浪费系统内存甚至移动终端运行速度。
作为本发明更优选的实施例，所述步骤S2还包括：
当检测到用户对移动终端触摸屏的拖动操作方向为向右时，则将与当前子照片相邻的左侧子照片移动至当前子照片的位置并进行实时显示；
当检测到用户对移动终端触摸屏的拖动操作方向为向左时，则将与当前子照片相邻的右侧子照片移动至当前子照片的位置并进行实时显示；
当检测到用户对移动终端触摸屏的拖动操作方向为向上时，则将与当前子照片相邻的下方子照片移动至当前子照片的位置并进行实时显示；
当检测到用户对移动终端触摸屏的拖动操作方向为向下时，则将与当
前子照片相邻的上方子照片移动至当前子照片的位置并进行实时显示。
本实施例以用户向左拖动触摸屏为例进行说明，如图4所示（其中加粗的框内为当前触摸屏显示的内容，非加粗框内为分割后的子照片），当前触摸屏显示内容为编号为[2，1]（即第2行第1列）的子照片，若用户向左拖动触摸屏，那么该子照片右侧的编号为[2，2]（第2行第2列）的子照片逐渐向左移动，而编号为[2，1]的子照片也同时向左移动（移动速度与[2，2]的子照片相同），在移动一段距离后，编号为[2，1]的子照片最终被替换为编号为[2，2]的子照片，并进行显示，需说明的是，这两张照片是实时移动并显示的，也就是说在中间状态，这两张照片可以同时显示，当移动到位后，前一子照片消失，后一子照片显示。
基于上述方法，本发明还提供一种大尺寸照片加载系统，如图5所示，其包括：
照片分割模块100，用于将所述大尺寸照片按预设尺寸分割成多个子照片；
显示处理模块200，用于依据用户对移动终端触摸屏的拖动操作方向，将下一子照片移动至当前子照片的位置并进行实时显示。
进一步，如图6所示，所述照片分割模块100包括：

判断单元120，用于判断所述大尺寸照片的尺寸是否大于尺寸阈值；
分割单元130，用于当所述大尺寸照片的尺寸超过尺寸阈值时，则对所述大尺寸照片进行分割。
进一步，所述分割单元中，在进行分割时，按照各子照片在所述大尺寸照片中所处位置，对各子照片依次采用二维矩阵的形式进行编号。
进一步，所述预设尺寸设置为与移动终端触摸屏大小一致。
所述显示处理模块200包括：
右移显示单元，用于当检测到用户对移动终端触摸屏的拖动操作方向为向右时，则将与当前子照片相邻的左侧子照片移动至当前子照片的位置并进行实时显示；
左移显示单元，用于当检测到用户对移动终端触摸屏的拖动操作方向为向左时，则将与当前子照片相邻的右侧子照片移动至当前子照片的位置并进行实时显示；
上移显示单元，用于当检测到用户对移动终端触摸屏的拖动操作方向为向上时，则将与当前子照片相邻的下方子照片移动至当前子照片的位置并进行实时显示；
下移显示单元，用于当检测到用户对移动终端触摸屏的拖动操作方向为向下时，则将与当前子照片相邻的上方子照片移动至当前子照片的位置并进行实时显示。
关于上述模块单元的技术细节在前面的方法中已有详述，故不再赘述。
综上所述，本发明将大尺寸照片按照预设尺寸分割成多个子照片，依据用户的触摸屏拖动操作显示相应的子照片。通过本发明，用户在按照拍摄尺寸查看照片时，只需加载分割得到的某个子照片，所以加载的照片尺寸小于实际拍摄尺寸，从而大大降低用户在查看大尺寸照片时所占用的内存空间，保证在查看大尺寸照片时系统能够稳定运行，并及时对用户的操作进行响应。
