Traditional high dynamic range (HDR) image generation algorithms such as multi-exposure fusion need to capture multiple images for algorithm fusion, which is not only slow but also occupies a lot of storage space, which limits the application of multi-exposure fusion technology. In this paper, the frequency division multiplexing method is used to separate the sub-images with different exposure values from a single snapshot image successfully. The resolution of HDR images generated by this method is almost the same as that of the traditional multiple exposure methods, the storage space is greatly reduced and the imaging speed is improved.
