Abstract: An image scanner including a camera portion which is provided with a lens, a CCD sensor and an optical glass component having a uniform thickness and refractive index greater than 1. The optical glass component is movable into and out of an optical path extending between an original and the CCD sensor. By the selective insertion of the optical glass component into the optical path, focussing and defocusing an image of the original is provided at the CCD sensor.
