PURPOSE: An image composition device for synthesizing an efficient image is provided to supply efficient WDR about a camera by supplying an image and synthesize the efficient image. CONSTITUTION: An image composition device for synthesizing an efficient image is as follows. A histogram calculation unit(110) calculates an exposure histogram and exposure brightness signal. An exposure calculation unit(120) calculates the shutter speed. The synthesis parameter calculation unit includes the intensity level translation table calculation unit and color difference weight calculating unit. The intensity level translation table calculation unit calculates the intensity level translation table.
