PROBLEM TO BE SOLVED: To contract a subject in a lower half of a photographing image.SOLUTION: In a image data conversion device, a photographing image of a subject to be projected from a fish-eye lens is stored in a storage part. A coordinate conversion is performed to the photographing image. Linearity toward a central position 34 of a horizontal line 31 is kept, and a linear shape of the subject orthogonal to a horizontal plane of a real space is kept parallel with a vertical axis of a display screen, and the linear shape of the subject orthogonal to a vertical plane including an optical axis of the fish-eye lens is kept parallel with a horizontal axis. As a result, although the photographing image is captured by the fish-eye lens, a display image can be formed that has an excellent perspective based on a linear line. |
