Abstract: A multi-frame image fusion method and system, an electronic device, and a storage medium are provided including performing image alignment based on a frame with highest exposure sharpness among a plurality of frames of images, wherein the image alignment includes extracting feature points of each of the plurality of frames to make the plurality of frames have a common spatial layout; calculating a fusion region of each frame based on local light source diffusion weight information in a spatial domain; performing image fusion on the plurality of frames with different exposures based on the fusion region, wherein the image fusion includes fusing the plurality of frames with different exposures into a fused image; and compressing the fused image to a preset dynamic range section. During the image fusion process, the local information is introduced into images to make the fused image possess a higher dynamic range and a lower halo.
