A wide dynamic range (WDR) hardware apparatus and a photographing apparatus including the WDR hardware apparatus are provided where the WDR unit applies weight coefficients to a luminance signal of a small size image having a first exposure time and a luminance signal of a small size image having a second exposure time longer than the first exposure time. The system combines the luminance signals applied weight coefficients, applies weight coefficients to a luminance signal of an original size image having the first exposure time and a luminance signal of an original size image having the second exposure time, and combines the luminance signals applied weight coefficients. |
