Paper Abstract

The original dynamic range of scene is generally limited to the capture sensors and display devices, and showed with the low dynamic range.Therefore, it is difficult to display the details in both dark and bright areas simultaneously. This paperadopted flexible thresholds combined with luminance map to improve the quality of image captured with unideal light distribution, and based on simple computation. The implementation effectively adjusts image contrast to both lowlight and highlight details while avoiding common quality loss due to halo-artifacts, desaturation and greyish appearance.
