ABSTRACT:
An image reading device for photographic printing comprising an optical lens mechanism, a monochrome CCD image device arranged at a focal position on an optical axis of the optical lens mechanism, a filter rotation plate having a plurality of color filters rotatably arranged on the optical axis, and a cut filter for blocking unnecessary light arranged on the optical axis, wherein a light quantity correction means for obtaining stepwise spectral characteristics is arranged on the optical axis. The reflected light due to the conventional ND coating and the influences of the boundary plane and the parallel degree between the cut filter and the color filter are disappeared, whereby the occurrence of flare, ghost and color divergence can be prevented.
