Document Type and Number:
WIPO Patent Application WO/2024/007948
Kind Code:
A1
Abstract:
The present application discloses a stroboscopic image processing method and apparatus, an electronic device and a readable storage medium, in the technical field of image processing. The method comprises acquiring a first image captured under a stroboscopic light source, the first image being an original RAW domain image; performing high-frequency and low-frequency image separation on the first image, to obtain a first high-frequency image and a first low-frequency image; determining a target mask according to the first low-frequency image, a mask value in the target mask being negatively correlated with the brightness and the degree of banding of the region in the first low-frequency image corresponding to the mask value; performing filtering processing on the banding in the first low-frequency image according to the target mask, to obtain a second low-frequency image, a RAW domain value located in a first region of the second low-frequency image being greater than a RAW domain value located in a second region of the first low-frequency image, the first region and the second region corresponding to each other, and both including a region where a banding is located and not including a region where a dark region is located; superimposing the second low-frequency image and the first high-frequency image, to obtain an output image.
