Abstract

The invention discloses an image acquiring method as well as a device and a mobile terminal. The image acquiring method comprises the following steps: monitoring an image displayed on a target screen, so as to confirm whether the image displayed on the target screen is changed or not; if the image displayed on the target screen is changed, taking a picture of the image displayed on the target screen, and confirming whether the same image exists in a database or not; if the same image does not exist in the database, storing the image displayed on the target screen in the database. By adopting the image acquiring method as well as the device and the mobile terminal, images which are displayed continuously can be automatically stored, and thus good convenience for later browsing is brought to users.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image acquisition method and device, and a mobile terminal. Background technique [0002] With the development of science and technology, academic exchanges are becoming more and more frequent, and the way of communication is also more and more inclined to multimedia playback, for example, teaching through a projector. [0003] When listening to a lecture taught by a projector, the listener can only browse the PPT courseware at the speed of the lecturer. Sometimes the speed of the lecturer is too fast for us to watch the PPT courseware, or the listener wants to record the PPT. When reading some content, the lecturer has already turned to the next page, which greatly reduces the efficiency of the lecturer's listening to the lecture. [0004] In order to solve the above problems, the existing technical solution is usually to video record the lecture. This incr...
