Abstract

The invention provides an image previewing and processing method, which comprises the following steps: acquiring data of an image and position data of a target area, obtained by carrying out detection on the target area; displaying the image in an operating area, and drawing the periphery and vertex of the target area on the image; cutting a thumbnail of the image according to the target area, thereby displaying a plurality of thumbnails in different scanning modes; through previewing, and according to the plurality of displayed thumbnails in different scanning 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.

Description

technical field

[0001] The invention relates to image processing technology, in particular to an image preview and processing method. Background technique

[0002] At present, in mobile Internet devices, there are many softwares for processing and extracting photographed pictures.

[0003] These software usually have two functions:

[0004] 1) Correction of whiteboard image

[0005] Whiteboard images are images taken of conference whiteboards, bulletin boards, and other text-like rectangular objects. The information that the user is interested in in the whiteboard image is generally within the rectangular area, while the captured picture has unwanted edge areas outside the target rectangular area. The part outside the target area can be removed by image processing, and the trapezoid can be converted into a regular rectangular figure.

[0006] 2) Enhancement of the whiteboard image

[0007] The image is enhanced through different scanning modes, so that the text informat...
