PROBLEM TO BE SOLVED: To generate a diagram viewing an object directly above and obliquely from a position in a detected three-dimensional space by detecting the position of the object in the three-dimensional space by using a plurality of photographed still pictures. SOLUTION: An image shift amount is detected from an image signal obtained by a lens group 21 and a CCD group 22, and data obtained by an angular velocity sensor 33 are recorded in a recording medium 14 together with the image signal. In the case of reproduction, a position of the object in a three-dimensional space is detected from the recorded data and the image signal. A diagram viewing the object directly above the position and a diagram viewed obliquely from the position are generated based on the position. In the case of photographing, a locus L of a moved digital camera is indicated on the diagrams viewed just above and viewed obliquely. Selecting an optional position in the diagrams viewed just above and viewed obliquely can display an image that is viewed from the selected position. |
