Zusammenfassung:A device is provided that generates a composite image using a first image and a second image having different exposure conditions. The device includes an image input unit 10, a likelihood calculating unit 13, an exposure estimating unit 14, and a compositing unit 16. The image input unit 10 inputs the first image and the second image. The likelihood calculating unit 13 calculates a subject motion likelihood at each pixel based on a difference between the first image and the second image. The exposure estimating unit 14 estimates an exposure transform function that conforms the exposure conditions of the first image and the second image to each other based on the subject motion likelihood. The compositing unit 16 composites the first image and the second image by using the exposure transform function.
