Embodiment Construction

[0073] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0074] A video camera is an electronic device for shooting video, and it has been widely used in the field of monitoring and security at present. In practical applications, the shooting effect of cameras in low-illuminance environments (such as nighttime environments, foggy environments, or rainy environments) is usually poor, because objects in the environment (such as human faces or The light intensity of the light reflected by the camera from the vehicle, etc.) to the camera is generally small, and the image formed by the camera on the object in the video based on the light of this small light intensity is often relatively blurred.

[0075] In order to ensure the shooting effect in a low-light environment, an illuminating ligh...

Abstract

The invention discloses an image processing method and device, equipment and a storage medium, and belongs to the technical field of image processing. The method comprises the following steps: acquiring a brightness value of ambient light entering the image sensor, wherein the ambient light comprises illuminating light which enters the image sensor and is emitted by the illuminating lamp and otherlight which enters the image sensor and is emitted by other light sources except the illuminating lamp; determining the brightness value of the illumination light according to the brightness value ofthe ambient light and the proportion of the illumination light in the ambient light; determining a distance coefficient of a foreground object according to the brightness value of the illuminating light, wherein the distance coefficient is used for indicating the distance between the foreground object and the illuminating lamp; and increasing the brightness value of a dark image region of a videoframe in a video shot by the camera according to the distance coefficient, wherein the brightness value of the dark image region is smaller than a target brightness threshold. According to the technical scheme provided by the embodiment of the invention, the problem of poor shooting effect of the camera can be solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, equipment and storage medium. Background technique [0002] In practical applications, in order to ensure the shooting effect of the camera in a low-light environment, a lighting lamp can be installed in the camera, so that when the ambient illumination is low, the lighting lamp can be used to supplement the environment to ensure the shooting effect of the camera. [0003] In the related art, in order to avoid overexposure of a foreground object (such as a person) in a video captured by a camera, the brightness of the illuminating lamp should generally not be too high. [0004] However, when the brightness of the lighting is not high, the background area in the video shot by the camera will be darker, and when the background area is darker, many details in the background area will be difficult to see clearly, which will affect ...
