PURPOSE: A wide backlight compensating apparatus is provided to increase the sharpness of an image after extracting edge information from the image by controlling the brightness of the image and to obtain an image of high contrast. CONSTITUTION: An edge extracting unit(131) extracts an edge having a first exposure time from a brightness signal. A brightness fusion unit(133) applies weight to the brightness signal. A reducing unit(134) reduces the output of the brightness signal having a second exposure time. A post-processing unit(136) combines the output of the edge extracting unit and the output of the brightness fusion unit. |
