Abstract
A color input image apparatus characterized by a support assembly, a sensor assembly, a beam forming assembly located between the support assembly and the sensor assembly, and a projector assembly located between the beam forming assembly and the sensor assembly. Apertures of the beam forming assembly and the projection assembly subtend substantially the same beam angle to minimize the deleterious effects of stray light. The beam forming assembly produces red, green, and blue component beams by transmissive filtering of light emanating from a portion of the color image. The beam forming assembly is positioned in the more position-tolerant object space of the apparatus, and matched apertures are used throughout to minimize the effects of stray light. Embodiments of the assembly can input an image from either color transparencies or from opaque color originals.
