PROBLEM TO BE SOLVED: To obtain a composition image in which a target subject has high quality, with a small processing amount.SOLUTION: At first, an image is captured by 3-stage exposure, the pixel level of low exposure image and intermediate exposure image is amplified, and matched to a high exposure image. Subsequently, a brightness synthetic ratio of each image is calculated on the basis of the low exposure image subjected to brightness matching. An image brightness synthetic ratio other than 0% in a target area is selected, and a composite image is generated by using only the image thus selected in the target area, and is substituted by a low exposure image, for example, in the other area. |
