Embodiment 1

[0035] figure 1 It is a schematic flow chart of a screenshot method of the present invention, and the method includes the following steps:

[0036] S1. Detect the user's screen capture command, and obtain the current screen image data of the terminal according to the screen capture command; the screen capture command can be a common screen capture command in the prior art, such as a combination of home key + screen lock key, which will not be done here limit. The current screen image data is original screenshot image data, that is, the original interface image data presented at the moment of screenshot.

[0037] S2, analyzing the image data, and judging whether there is a first content in the image data; the first content is the content preset by the user, and the content can be specific text data or specific graphic data. This is not limited. The parsing of the image data is realized by a conventional image parsing algorithm in the field, which is not limited here.

[003...

Embodiment approach

[0042] As a preferred embodiment, the method also includes:

[0043] Receive the first content set by the user;

[0044] Parsing the image data, judging whether there is a first content in the image data, and if so, identifying one or more of the first contents of the image data, if all the first contents belong to the user If the first content is set, the rectangular area of ​​the image data where the first content is located is automatically cut off, and the remaining area of ​​the image data is automatically stretched to be consistent with the size of the image data; and automatically saved The stretched image data is screenshot image data.

[0045] Preferably, if the first content set by the user, that is, the privacy information, is wireless local area network information, battery level information, bluetooth signal information, and system mode information, and the first content analyzed in the image data obtained by screenshots is wireless local area network information...

Embodiment 2

[0052] The present invention proposes a screen capture device, which includes the following modules:

Abstract

The application relates to the technical field of the mobile terminal, and in particular relates to a mobile terminal screenshot method and device. The method comprises the following steps: identifying the content in an image data specific region, judging whether the content is the user preset content, namely, the privacy content, and then synthesizing the image data and the image covered by the preset content into screenshot data. Therefore, the user privacy is protected, and the modification trace on the screenshot image caused by deducting the preset content is avoided, and the vivid display of the screenshot image is realized. Furthermore, the stretching on the image data obtained after deleting a rectangular region of the image data cannot cause the serious distortion of the image since the occupied area of the rectangular region of the image data is small, and the user privacy is protected.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and in particular to a screen capture method and device for a mobile terminal. Background technique [0002] With the popularization of smart mobile terminals, more and more people need to save the content of the screen when using the mobile terminal. Usually, smart phones can capture the entire screen through hardware buttons or software operations or gestures. But often what people need is only a part of the screen. This means that they have to capture the entire screen, edit it in the image application software, and use it after cropping, marking and other operations. There are many steps. Today, with more and more emphasis on personalization, the use of screen patterns is also more and more about personalization and convenience. There is undoubtedly a great demand for randomly intercepting graphics of any shape. [0003] In the prior art, the document CN103530056A proposes...
