IMAGE GENERATION DEVICE, COORDINATE CONVERSION TABLE CREATION DEVICE AND CREATION METHOD

An image generation device performs coordinate transformation, based on a coordinate transformation table, to a two-dimensional first image having a span in a horizontal direction and a vertical direction and acquired by overlooking and imaging an object from a first viewpoint at a first depression angle, and generates and outputs a second image which was obtained by overlooking the object from a second viewpoint which is different from the first viewpoint at a second depression angle which is different from the first depression angle. The coordinate transformation table is a table for transforming coordinates of a plurality of first selected pixels selected from a plurality of first pixels constituting the first image into coordinates of second selected pixels corresponding to a plurality of second pixels constituting the second image. The first selected pixels of the coordinate transformation table is set so that, when a region of the first image is divided into a plurality of regions in the vertical direction based on at least one pixel boundary line extending in the horizontal direction, an array pitch of the first selected pixels in a region on a lower side in the vertical direction of the first image becomes rougher than an array pitch of the first selected pixels in a region on an upper side in the vertical direction of the first image.
