Embodiment approach

[0143] The image brightness adjustment method in the present invention can individually adjust the brightness of the moving area in the video image, so that the brightness of a specific area in the video image can be changed accordingly according to the actual needs of the user, and the multi-frame video image can be presented with better quality. The best effect, the user can obtain clearer and complete image information, and the user's visual experience is excellent; therefore, the image brightness adjustment method can be applied to various technical fields, and the image brightness adjustment method is applied to teaching video images below In this, the implementation manner of the image brightness adjustment method of the present invention is described in this way, specifically as follows:

[0144] By obtaining teaching video images within a preset continuous time; the teaching video images include corresponding video information, which contains the teacher's lecture conte...

Abstract

The invention discloses an image brightness adjusting method and device. The image brightness adjusting method comprises: collecting a video image of a target area is collected; obtaining a motion area of the video image; dividing the motion area into a plurality of rectangular areas to determine a plurality of sub macro blocks; wherein the sub macro blocks are rectangles with preset pixel widthsand preset pixel lengths; and finally, carrying out brightness enhancement on the plurality of sub macro blocks according to an enhancement algorithm coefficient. Due to the fact that only the brightness of the moving area in the video image is independently adjusted, the display effect of the image is improved, and the efficiency of brightness adjustment of the moving area is improved by conducting sub-macro-block division on the moving area.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to an image brightness adjustment method and device. Background technique [0002] Image processing (Image Processing) technology refers to the analysis of images through various pixel processing methods, so that the processed images can achieve the preset effect, meet the different visual needs of users, and bring users a good visual experience. Image processing in traditional technologies usually adopts digital image processing methods. Digital image refers to the use of digital cameras, scanners and other electronic equipment to obtain image data. After in-depth processing and transformation of image data, the display state of the original image is changed, such as changing the color of the image. The image can be customized according to the actual needs of users. Change its own parameters so that the changed image can be widely used in various industrial technical fiel...
