Processing method for shot picture and device, equipment and medium

Abstract

The invention discloses a processing method for a shot picture, and the method comprises the steps: determining a target exposure time length and the target brightness of a target shot picture through a current environment parameter and a current equipment parameter of shooting equipment; and collecting the original picture under the target exposure duration to obtain the original picture with the original brightness smaller than the target brightness, thereby facilitating subsequent gain processing; and calculating to obtain a global gain value and a difference gain value for different gain processing methods, performing difference gain processing on a target region in the original picture according to the difference gain value during gain processing, and performing global gain processing on a remaining non-target region in the original picture according to the global gain value; and if the target area does not exist, performing global gain processing on the whole original picture. According to the invention, gain processing is selectively carried out on different objects in the picture, so that the picture can obtain the best balance between clearness and color fullness. In addition, the invention further provides a processing device and equipment for the shot picture and a medium.

Description

technical field [0001] The present invention relates to the technical field of camera picture processing, and in particular to a processing method, device, equipment and medium for shooting pictures. Background technique [0002] In the actual video shooting scene, it is difficult to take into account the image details of high and low light differences. For example, in a frame recorded by a driving recorder, the upper half of the frame is the sky, the lower half is the road, and the real focus of the frame is near the center line of the frame, including vehicles, license plates, and pedestrians. For this picture, the upper half of the picture pursues a glamorous visual perception, requiring contrast and visual saturation. Near the center line of the screen is the focus of video shooting, and it is required to be as clear as possible. Although the lower edge of the screen is an inevitable scene, the sense of this part of the screen is completely unimportant. If you simply ...

Problems solved by technology

If you simply increase the exposure time to make the blue sky and white clouds have a glamorous image, then these shooting points in the scene will inevitably lose details and line sense due to overexposure

And if you want to pursue the clear presentation of these overexposed objects, you must reduce the overall exposure time, and this will definitely reduce the overall bright and beautiful look of the picture.
