modes, selecting one of the scanning mode; and preprocessing the image according to the current target area and the selected scanning mode. Compared with the prior art, the method provided by the invention mainly has a characteristic that: after carrying out self-defined
cutting on the obtained image in the target area, a plurality of thumbnails corresponding to the image in different scanning
modes are displayed and previewed by users in real time so as to help the users to rapidly select the most
ideal image processing scheme to finally obtain an image required by the users; therefore, the method is convenient and fast, and has a good user interaction experience.
