Local Histogram Equalization (LHE), which is efficient for High Dynamic Range (HDR) compression, requires a large amount of calculation and induces unnatural image quality. Using checker-wise histogram acquisition and line buffer, memory accessing for local histograms is processed in O(1) time. For improving image quality, we proposed approximation of LHE by compositing gamma functions. Moreover the weighting of local histogram is developed by introducing mean values of bins for the suppression and control of halo effect. We set the range of parameters for controlling halo effect by sensitivity evaluation. |
