Abstract
An image generation device generates an output image based on input images captured by three cameras. An input image portion corresponding to an overlap region of imaging ranges of the cameras forms a lattice pattern in the output image. The lattice pattern uses, as a unit pattern, lattice points divided by circles drawn by waves around two cameras. Pixel values of the unit pattern are obtained by weight-averaging pixel values of first and second input images. A weighted average value of pixel values of the first input image is equal to or larger than a weighted average value of pixel values of the second input image in one of two unit patterns through which an abdominal line and a nodal line pass, and is equal to or smaller than the weighted average value of the pixel values of the second input image in the other one thereof.
