An image processing apparatus cuts out a plurality of background images and foreground images from a plurality of images, and stores a plurality of cutout foreground images and an alignment coefficient calculated from an image prior to cutout of each foreground image, the plurality of foreground images being stored in association with the alignment coefficient. Moreover, the image processing apparatus generates a background combined image by combining cutout background images, and selects any of the stored foreground images based on designation of a position in the background combined image. Then, image processing apparatus determines an alignment coefficient of the selected foreground image by using the alignment coefficient associated with the selected foreground image, and combines the selected foreground image and the background combined image.
