Abstract
A method of image processing includes: providing a radiance map, generating a first image in which an edge part is preserved and a flat part is smoothed by applying an edge preservation smoothing filter to the radiance map, generating a second image having a visually perceivable dynamic range by applying a correction curve to the first image, and generating a display image having corrected lightness by adjusting a hue value and a chroma value of the second image.
