Abstract:
A device for reading color images, comprising:an optical input unit having a predetermined valid reading width for inputting three colors of RGB concurrently, said optical input unit comprising reflectors arranged facing each other at a distance substantially equal to the predetermined valid reading width;a first optical path for radiating an RGB light input from said optical input unit;a second optical path for radiating an RGB light input from said optical input unit in a path different than the first optical path;a third optical path for radiating an RGB light input from said optical input unit in a path different than the first optical path and the second optical path;an optical resolution unit receiving three RGB lights that are incident to said optical input unit through the first optical path, the second optical path and the third optical path to resolve one of the three RGB lights into an R light, resolve one of remaining two RGB lights into a G light and resolve the other one into a B light; anda photoelectric conversion unit comprising an R reading pixel, a G reading pixel and a B reading pixel corresponding to the R light, the G light and the B light obtained in said optical resolution unit, and converting the R light, the G light and the B light into an R signal, a G signal and a B signal.
