Abstract

An embodiment of the invention relates to a method for High Dynamic Range (HDR) image creation by generating a mean difference curve for use in aligning the images of a sequence of images taken with different exposures, wherein the difference in exposure might derive from a difference in exposure time or a difference in aperture size. A further embodiment of the invention relates to a method for HDR image creation by generating images with different exposures from a single image. A further embodiment of the invention relates to a method for HDR video creation by generating frames with different exposures from a single frame.
