An image generation device (100) generates an output image based on at least three input images obtained by taking images by at least three image-taking parts mounted to a body to be operated and having different optical axis directions. A coordinates correspondence part (10) causes coordinates on a columnar space model arranged to surround the body to be operated to correspond to coordinates on at least three input image planes on which the at least three input images are positioned, respectively. An output image generation part (11) generates the output image by causing values of the coordinates on the at least three input image planes to correspond to values of the coordinates on an output image plane on which the output image is positioned through coordinates on the columnar space model (MD). The columnar space model (MD) is a combination of a plurality of space model parts (MD1, MD2) each having a reference axis. The columnar space model corresponds to a pair of adjacent image-taking parts from among the at least three image-taking parts, and an optical axis of each of the pair of image-taking parts intersects with the reference axis of a corresponding one of the space model parts. |
