Abstract
Disclosed are a high dynamic range imaging method and apparatus. The high dynamic range imaging method includes: (a) acquiring a first low dynamic range (LDR) image, a second LDR image, and a third LDR image having different exposure values; (b) applying the first, second, and third LDR images to a weight map estimation model to extract a weight map, and integrating the first, second, and third LDR images using the extracted weight map to generate an input feature map; and (c) applying the input feature map to a Swin-Fourier convolution network model to perform Fourier transform and convolution on the input feature map, and then connecting a reference feature map to generate a high dynamic range (HDR) image.
