Abstract
A processing-target image creating device creates a processing-target image based on a plurality of input images. The processing-target image creating device includes a coordinates-associating part configured to associate coordinates on each input image plane on which each input image is positioned, coordinates on a space model onto which each input image is projected, and coordinates on a processing-target image plane, and an image adjusting part configured to adjust the processing-target image by determining for each input image a re-projection angle of a re-projection line joining the coordinate and the coordinate. The image adjusting part determines for each input image slopes of the re-projection lines such that each coordinate on the processing-target image plane corresponding to an infinity line in each input image corresponds with each other on a dividing line between image parts corresponding to each input image on the processing-target image plane.
