Abstract

The invention discloses an image acquisition method, device, system, terminal equipment and storage medium. The method includes: receiving and displaying image data; the image data comes from a multimedia device; monitoring the operation on the display screen; parsing the focus instruction corresponding to the operation; acquiring the position information of the operated area on the display screen; sending the position information to the multimedia device to Make the multimedia device focus on the target area, where the target area is the area corresponding to the location information on the multimedia device. The present invention receives the image data from the multimedia device, and after performing the focusing operation on the display screen, accurately acquires the position information of the operated area on the display screen, so that the area corresponding to the position information on the multimedia device can be accurately focused, and the operation is convenient and accurate high.

Description

technical field [0001] Embodiments of the present invention relate to multimedia equipment technologies, and in particular to an image acquisition method, device, system, terminal equipment, and storage medium. Background technique [0002] With the development of science and technology, multimedia teaching has become one of the forms of daily teaching. In the process of multimedia teaching, images of the objects to be displayed can be captured by cameras or high-speed cameras on the physical booth, and the captured images can be projected onto the screen for viewing. The viewer can observe the object to be displayed more clearly through the projection on the screen. [0003] At present, when using a physical booth or a high-speed camera to capture images, the user generally needs to manually adjust the camera of the physical booth or the high-speed camera to focus, and it is difficult to ensure the accuracy of the focus during the manual adjustment process. Contents of th...
