摘要： 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.
