Panorama image generation program, panorama image generation apparatus, and panorama image generation method

A panorama image generation apparatus that generates a panorama image based on video encoded data obtained by encoding a motion picture photographed by means of a moving camera, comprising:

• a decoding processing section that decodes the video encoded data to acquire a frame image and motion vectors;
• a camera position information generation section that calculates movement information of the frame image based on the motion vectors and calculates camera position information representing the position of the camera based on the movement information of the frame image;
• and
• a display data generation section that generates display data obtained by processing the frame image based on the camera position information corresponding to the frame image.
