A method for compressing an intensity dynamic range of an input image to a reduced
intensity dynamic range of an image display device includes defining a plurality
of units of the input image, determining a local mean estimate of an intensity
of each of the plurality of units of the input image, generating a contrast modification
processing value for each local mean estimate, and generating an output intensity
value, for each local mean estimate, by using only the generated contrast modification
processing value and an input intensity value.
