1. An image synthesis system for synthesizing a global shutter image based on a rolling shutter image, the image synthesis system arranged to:
project a rolling shutter image captured by a rolling shutter camera in a moving aerial camera system, the rolling shutter image having a plurality of scanlines having associated different position and pose information, to a 3D object space, the 3D object space including information indicative of height of features in the 3D object space, by projecting each scanline of the rolling shutter image from a camera optical center determined for the scanline using the position and pose information associated with the scanline, each scanline having a different camera optical center, by ray tracing each pixel of the rolling shutter image from the rolling shutter image to the 3D object space; and
project, subsequently, from the 3D object space to a synthetic global shutter image by ray tracing each pixel from the 3D object space to the synthetic global shutter image.
