Exposure brightness control method, device, electronic equipment and storage medium

Abstract

The invention discloses an exposure brightness control method, device, electronic equipment and storage medium, which are used to solve the problem in the related art that the shooting effect is greatly affected due to the incorrect adjustment of the exposure brightness of an image acquisition device. In the embodiment of the present disclosure, the scene category to which the target image belongs is obtained by analyzing the brightness distribution characteristics of different image blocks of the same target image, and then the exposure brightness suitable for the current scene category is determined according to the scene category. That is, the exposure brightness suitable for the current actual situation (that is, the scene type) is selected to realize the exposure control, so that the control of the exposure brightness can be adaptive to different scene types. The method can realize automatic adjustment of exposure brightness and at the same time reduce or even avoid overexposure or severe underexposure of the collected image as far as possible compared with simply relying on the global illuminance value of the image to determine the exposure brightness.

Description

Technical field [0001] The present invention relates to the field of camera image technology, and more particularly to an exposure brightness control method, apparatus, electronic device, and storage medium. Background technique [0002] As the monitoring camera is more extensive, the scenario environment that needs to be monitored is not only complicated, but also needs to monitor the scene to surveillance. When the monitoring scene of different weather environment and time sections, the problem of most of the monitoring cameras is: [0003] First: Some surveillance cameras do not have adaptive exposure methods, need people to participate, and do not apply to monitoring of such complex and multi-change environments such as partially dark spaces. [0004] Second: Common adaptive exposure mode multi-reference images After adaptive exposure, this exposure method is easily easy to monitor the display of excessive or severe exposure, affecting the monitoring effect. Inventive conten...

AI Technical Summary

Problems solved by technology

[0003] First: Some surveillance cameras do not have an adaptive exposure method, which requires human participation, and is not suitable for monitoring complex and changeable environments such as some bright and dark areas

[0004] Second: The common adaptive exposure method refers to the global illuminance value of the image before performing adaptive exposure. However, this exposure method can easily cause the surveillance camera to appear overexposed or seriously underexposed, which affects the monitoring effect.
