A region-of-interest setting portion sets, during image pickup, a region of interest in an image picked up using a camera built in portable equipment. A component image generation unit generates a component image in which, with the image picked up using the camera built in the portable equipment, posture information of the portable equipment and the region-of-interest information set by the region-of-interest setting portion are associated. A panoramic image generation unit combines a plurality of component images between which the posture of the portable equipment is different to generate a synthesis image.
