Embodiment Construction

[0056] Before the technical solutions of the embodiments of the present invention are described in detail, related technologies are first introduced and described.

[0057] In the related art, the same tone mapping curve, such as a gamma curve, can be used to perform tone mapping on the captured images of multiple frames, so as to preserve information such as color, contrast, details and the like in the images to the maximum extent. However, when the illumination of the shooting scene changes, using the same gamma curve to perform tone-mapping on the multiple frames of images captured will result in discontinuous and unnatural display effects in the overall video stream after tone-mapping processing.

[0058] Based on this, in various embodiments of the present invention, video data to be processed is acquired; the video data to be processed includes at least two images and attribute information respectively corresponding to the at least two images; The attribute information c...

Abstract

The invention discloses an image processing method, device, electronic equipment and storage medium. Wherein, the method includes: acquiring video data to be processed; the video data to be processed includes at least two images and attribute information respectively corresponding to the at least two images; using the attribute information respectively corresponding to the at least two images, Determine the values ​​corresponding to the at least two images respectively, and obtain at least two values; the values ​​represent the brightness value of the ambient light when the image is taken; based on the at least two values, determine the values ​​corresponding to the at least two images respectively Tone mapping curves of the at least two images; performing tone mapping processing on the at least two images respectively by using the tone mapping curves respectively corresponding to the at least two images, to obtain at least two processed images.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image processing method, device, electronic device and storage medium. Background technique [0002] With the rapid development of image processing technology and the increasing data volume of captured video images, it becomes more and more necessary to perform tone mapping processing on captured video images. In the related art, the same tone-mapping curve is used to perform tone-mapping on multiple frames of images captured, so as to maximize the retention of information such as color, contrast, details and the like in the images. However, when the illumination of the shooting scene changes, using the same tone mapping curve to perform tone mapping on the multiple frames of images captured will result in discontinuous and unnatural display effects in the overall video stream after tone mapping processing. SUMMARY OF THE INVENTION [0003] In view of this, embodiments...
