Abstract
The image pickup device includes a plurality of plane mirrors arranged in the form of a polygonal pyramid, and a plurality of cameras disposed opposite the plane mirrors, respectively. The angle of incidence of a ray passing along the optical axis of a lens of the camera on the plane mirror is set to be less than 45 degrees.
Claims4
