Abstract

PURPOSE: To improve resolution by dividing an image forming optical path into three colored optical paths, reading each formed image by photoelectric transducer (CCD) and substantially making each divided, colored and formed image flush with each other.
CONSTITUTION: Dichroic mirrors 2 and 3 have light spectroscopic and transmitting characteristics, and their faces 10 and 13 fully reflect light. Light which perpendicularly makes incident on the face 10, reflected by the dichroic mirror 2, passes through a route GNOP, and forms an image on the CCD 4. Light which passes through the dichroic mirror 2 and is reflected by the dichroic mirror 3 passes through a route GNHIJ, and forms an image on the CCD 5. Light which passes through the dichroic mirrors 2 and 3 passes through a route GNHEF, and forms an image on the CCD 6. Therefore, blue, red and green images are formed on the CCDs 4W6. Light split in plural colors perpendicularly goes out of the same plane 11 and forms images the same distance away from the plane 11; therefore the images in different colors are flush with the plane. Thus resolution of the titled device is improved, compared with that of a color stripe filter splitting light into two colors.
