The first optical element guides light from a wide angle range in a forward slanting lower side direction onto the image pickup lens, and forms the light as an image in the image pickup element via the image pickup lens. The second optical elements guide lights from non-wide angle ranges in both left and right side directions onto the image pickup lens, and form these lights as images in the image pickup element via the image pickup lens.
