通过上述步骤S311获取到A终端当前显示的图片的参考点在图片调节操作前的第一坐标值(x1，y1)和图片调节操作后的第二坐标值(x2，y2)后，先分别计算所述第一坐标值(x1，y1)与参考坐标轴原点的距离d1以及所述第二坐标值(x2，y2)与参考坐标轴原点的距离d2。具体地，所述第一坐标值(x1，y1)与参考坐标轴原点的距离d1＝(x1 2+y1 2)1/2；所述第二坐标值(x2，y2)与参考坐标轴原点的距离d2＝(x2 2+y2 2)1/2。然后，根据所述第一坐标值(x1，y1)与参考坐标轴原点的距离d1以及所述第二坐标值(x2，y2)与参考坐标轴原点的距离d2，计算所述距离d2与所述距离d1的比值k，也即k＝d2/d1＝(x2 2+y2 2)1/2/(x1 2+y1 2)1/2，将计算获得的所述比值k作为所述图片调节操作对应的调节系数。本领域技术人员可以理解的是，还可以通过其他方法计算所述调节系数。例如，可直接通过计算所述第二坐标值(x2，y2)中参数x2与所述第一坐标值(x1，y1)中参数x1的比值，将计算获得的所述参数x2与所述参数x1的比值作为所述调节系数。
之后，A终端发送携带所述调节系数信息的图片调节指令至所述B终端，以供所述B终端根据所述调节系数，调节所述B终端当前显示的图片的尺寸，对所述图片进行同步放大或者缩小处理。
