Abstract
An embodiment of the invention relates to a method for generating a radiance map in High Dynamic Range (HDR) image creation by calculating mean difference curves for a sequence of images taken with different exposures and a transformation curve from the mean difference curve by an algorithm approximated to the Debevec function, by the means of which a radiance map can be calculated from the taken images. A further embodiment of the invention relates to a unit for performing this method.
