An image system which captures, along with the images, information defining both the position and the orientation of the camera along with the distance to the subject. The present invention uses a low-noise multi-wavelength light source which has sufficiently low noises at respective wavelengths, while being lasing at a multi-wavelength. The connector is mounted on a printed circuit board in a manner that a flange of the mating board abutting against a front edge of the printed circuit board and the base abutting against a top surface of the printed circuit board.
