Abstract

一种拍摄图像的方法，基于拍摄指令，在所述四边形图像内选定至少一个焦点，并以所述至少一个焦点对焦拍摄至少一张初始图像，其中，所述四边形图像包括第一组对边和第二组对边，所述第一组对边的对边夹角小于所述第二组对边的对边夹角，第一边为所述第一组对边中较短的一边，所述至少一个焦点包括第一焦点，所述第一焦点在所述四边形图像内且在第一边一端的部分区域中；然后校正为矩形图像后，得到最终图像并输出。通过选定与被拍摄的矩形目标远端对应的部分区域中的点作为焦点进行对焦拍摄初始图像，能够提高初始图像中与所述矩形目标远端对应的部分区域的分辨率，以增加该部分区域的校正插值的来源像素，提高最终图像的清晰度。
