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 application discloses an image processing method, device, equipment and storage medium, belonging to the technical field of image processing. The method includes: acquiring the brightness value of the ambient light incident on the image sensor, the ambient light comprising the illuminating light emitted by the illuminating lamp incident on the image sensor and the illuminating light incident on the image sensor by the illumination Other lights emitted by light sources other than lamps; determine the brightness value of the lighting light according to the brightness value of the ambient light and the proportion of the lighting light in the ambient light; determine the distance coefficient of the foreground object according to the brightness value of the lighting light , the distance coefficient is used to indicate the distance between the foreground object and the illuminator; according to the distance coefficient, the brightness value of the dark image area of ​​the video frame in the video captured by the camera is increased, and the brightness value of the dark image area is less than Target brightness threshold. The technical solution provided by the embodiment of the present application can solve the problem of poor camera shooting effect.

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 ...
