Taking Images in Extremely High Dynamic Range Scenes by Fusing Multiple Exposed Images And Tone Reproduction

This paper presents an integrated color imaging system for taking images in extremely high dynamic range scenes. The system first fuses five differently exposed images in raw data such that the effective dynamic range of the fused raw data is extended to 256 times. Then it runs several edge detection iterations to extract the image details in different luminance levels and assigns larger dynamic range for highly populated regions.
