APPARATUS AND METHOD FOR GENERATING HIGH DYNAMIC RANGE IMAGE BASED ON SINGLE FRAME

摘要

PURPOSE: An apparatus and method for generating an image with a high dynamic band based on a single frame are provided to synthesize a plurality of LDR images and an HDR result image by generating the plurality of LDR images from one original image. CONSTITUTION: A histogram extension unit(110) generates a plurality of LDR(Low Dynamic Range) images with different luminance distributions by separating a luminance histogram of an original image into a plurality of partial histogram groups based on a preset critical value and extending the plurality of partial histogram groups. An HDR(High Dynamic Range) image synthesizing unit(120) generates an HDR result image by synthesizing the plurality of LDR images.
