PROBLEM TO BE SOLVED: To efficiently generate and hold panorama images for regenerating a virtual space in building a walk-through virtual space, using IBR technique. SOLUTION: Plural pieces of frame data are generated and held, based on image data obtained by photographing, while moving plural image pickup devices to photograph in different directions. From the plural thus held pieces of frame data, a frame data group comprising frame data determined as being photographed at the same position are extracted as a frame data group comprising continuous frame data (S101-110). For the extracted frame data, the frame data are deleted, so that one piece of frame data exists for one position (S106, S111). In this way, in storing the frame data corresponding to the plural positions in a map, thinned-out frame data are stored to correspond to position in the map. |
