PROCESSING TARGET IMAGE GENERATION DEVICE, PROCESSING TARGET IMAGE GENERATION METHOD, AND OPERATION SUPPORT SYSTEM

A processing-target image generation device (100) generates a processing-target image which is an object to be subjected to an image conversion process for acquiring an output image based on an input image taken by an image-taking part. A coordinates correspondence part (10) causes input coordinates, spatial coordinates, and projection coordinates to correspond to each other, the input coordinates being on an input image plane on which the input image is located, the spatial coordinates being on a space model (R1, R2) on which the input image is projected, the projection coordinates being on a processing-target image plane (R3) on which the processing-target image is positioned and the image projected on the space model is re-projected.
