An image generating apparatus, which generates monitor image data from camera image data through a viewpoint transformation, includes a rear camera 1, an image processing controller 2, and a monitor 3. The image processing controller 2 sets a first virtual camera by viewpoint shift to have a downward viewpoint from a higher position than that of the rear camera 1, and sets a second virtual camera by rotating a viewpoint thereof upward or downward from the viewpoint of the rear camera 1, and generates the monitor image data of a close view viewed from the first virtual camera, and of an intermediate-to-distant view viewed from the second virtual camera, from the single camera image data captured by the rear camera 1. The monitor 3 displays a synthesis image in which a downward view of the close view and a perspective image of the intermediate-to-distant view are synthesized.
