Abstract
An apparatus for HDR image processing is provided. The apparatus determines an imaging sensitivity value. The apparatus then compares subsets of imaging information with the determined imaging sensitivity value and applies a gamma correction to each subset of imaging information using a gamma low contrast curve or a gamma high contrast curve based on the comparison to obtain the gamma corrected subset of imaging information.
