A control point detector detects controls points, with which moving images are associated with a region of a panoramic image, by detecting feature points between the panoramic image and a frame of part of the moving images. An alignment processing unit adjusts the alignment of the moving images relative to the panoramic image, based on the control points. A mapping processing unit maps the panoramic image and a still image frame of the moving images the alignment of which adjusted by the alignment processing unit, onto a three-dimensional (3D) panoramic space as textures. A 3D image generator generates a 3D panoramic image, when the three-dimensional panoramic image is viewed in a specified line of sight. When a moving image reproduction unit receives instructions to reproduce the moving images in the 3D panoramic image, the moving image reproduction unit reproduces the moving images.
