Abstract: An image composition apparatus that is capable of acquiring a high-quality composite image that keeps continuity of the gradation of the whole image. Different exposures are set for images to be taken. Each of taken images is divided into small regions. A measured value is found based on brightness values in each of the small regions. A comparison value for each of the small regions is calculated based on the measured value of a small region of one image and the measurement value of the same small region of another image. A representative value is calculated based on the comparison values calculated for the respective small regions. A level-matching gain used for compositing the image data of the images is calculated based on an exposure level difference and the representative value. The image data of the images of which the image levels are adjusted are composited by multiplying the gain.
