Abstract
An image reading apparatus in which extended image reading time is prevented when high quality image data is obtained, which image data is corrected by invisible light such as infrared light which is transmitted through an original. In a CCD scanner, visible light emitted from a light source is irradiated onto a photographic film. Infrared light emitted from the light source is reduced by an IR light reducing filter to be irradiated onto the photographic film. Visible light which has been transmitted through the photographic film is irradiated on a linear CCD by a lens unit, and the infrared light is reflected by a dichroic mirror to be irradiated on the linear CCD. Accordingly, the reading of invisible light can be effected at the same time that the reading of visible light is effected. It is therefore possible to prevent image reading time from becoming long due to the time required for the receiving of invisible light.
