Processing method, device, equipment and medium of shooting pictures

Abstract

The invention discloses a method for processing a shooting picture, which includes: determining the target exposure time and the target brightness of the target shooting picture through the current environment parameters and the current equipment parameters of the shooting equipment. The original image is collected under the target exposure time to obtain an original image with an original brightness lower than the target brightness, which facilitates subsequent gain processing. Then calculate the global gain value and differential gain value for different gain processing methods. When performing gain processing, perform differential gain processing on the target area in the original picture according to the differential gain value, and perform differential gain processing on the target area in the original picture according to the global gain value. Non-target regions are processed with global gain. If there is no target area, the global gain processing is performed on the entire original image. The invention selectively performs gain processing on different objects in the picture, so that the picture can achieve the best balance between clarity and full color. In addition, a processing device, device and medium for photographing pictures are also proposed.

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.
