Method for realizing screenshot through touch screen and mobile terminal

Abstract

The invention provides a method for realizing screenshot through a touch screen, and a mobile terminal. The method includes a first step of starting a partial screenshot function, cutting out a full screen image as an initialization selected area to display, a second step of catching and recording an input sliding track of a user in the initialization selected area, a third step of recognizing a closed curve contained in the sliding track and confirming an area surrounded by the closed curve to be the selected area, or recognizing the sliding track as an open curve (the sliding track divides the initialization selected area into at least two areas) and confirming one area to be the selected area according to a selection instruction of the user, and a fourth step of storing the range, corresponding to the selected area, of the full screen image to be a screenshot. Through adoption of the method, the user can intercept images with any shapes through an instant messaging client-side and sends the images to other instant messaging client-sides. Practicality of instant messaging (IM) software and flexibility in the screenshot process are greatly improved, and user experience is also improved.
