Embodiment 1

[0061] Teachers need to explain the test papers during class, only need to obtain the test questions, and the rest are not required, such as figure 2 As shown, the steps to obtain the test question image are as follows:

[0062] S1: Preview and shoot the content of the test paper with a high-speed camera, and display the content of the test paper captured in the preview mode on the computer display screen in real time;

[0063] S2: Calculate the size ratio between the dynamic image on the computer display screen and the dynamic original image of the Altimeter;

[0064] Specific steps are as follows:

[0065] S201: Obtain the original image size of the high-speed camera dynamic image (the original image size can be obtained through the high-speed camera resolution size), the high-speed camera dynamic original image size is 4032×3016px;

[0066] S202: Obtain the dynamic image display image size of the computer display screen (the display image size can be obtained through the computer d...

Embodiment 2

[0085] During the experiment demonstration process, it is necessary to save the image of the equipment and operation method of the experiment demonstration. The rest of the operating environment and background are not required. The image acquisition steps are as follows:

[0086] S1: Take a picture of the experiment demonstration process with a camera, and display the dynamic image content taken in preview mode on the computer display screen in real time;

[0087] S2: Calculate the size ratio between the dynamic image of the computer display screen and the dynamic original image of the camera;

[0088] Specific steps are as follows:

[0089] S201: Obtain the original image size of the camera dynamic image (the original image size can be obtained by the camera resolution size), for example, the camera dynamic original image size is 4032×3016px;

[0090] S202: Obtain the dynamic image display image size of the computer display screen (the display image size can be obtained through the com...

Abstract

The invention discloses a method for defining static high-definition image photographing areas under dynamic image previews and relates to the technical field of image processing. The method comprisesthe following steps of S1, obtaining original dynamic images in real time and displaying the original dynamic images on a display screen, thereby obtaining display screen dynamic images; S2, calculating a size proportion between the display screen dynamic images and the original dynamic images; S3, intercepting image areas in the display screen dynamic images; and S4, on the basis of the size proportion, obtaining and displaying the image areas in the original dynamic images corresponding to the intercepted image areas. The problem that in an existing image interception mode, the interceptedimages are unclear and the original high-definition images cannot be obtained or the intercepted high-definition images are integrated images, secondary clipping needs to be carried out, and the operation is complex is solved.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for defining a static high-definition image shooting area under a dynamic image preview. Background technique [0002] At present, with the popularization and application of information-based teaching equipment, the traditional "blackboard + chalk" classroom teaching is gradually being upgraded to multimedia-assisted teaching based on computer networks, large-screen display devices, and voice systems. In order to further promote the application of school informatization teaching and improve teaching level and efficiency, more and more schools have introduced video display systems for shooting teaching materials (for example: experimental demonstrations, test paper explanations, example questions explanations, etc.). [0003] Real-time shooting of real objects and various printed materials through camera equipment, and synchronized to the large screen for displa...
