Image reading apparatus
摘要:
Transmitted light from a transmitting original recording medium based on light from a first light source which emits light in at least the visible light range is introduced to a solid imaging element via an infrared cutout filter. Image information recorded on the transmitting original recording medium is read based on signals obtained from the solid imaging element. Transmitted light from a transmitting original recording medium, based on light from a second light source, which emits light only in the infrared range, is introduced to the solid imaging element without passing through the infrared cutout filter. Defect information of the recording medium itself is read based on signals obtained from the solid imaging element, so that the read defect information can be removed from the read image information. This enable the recorded image on the film to be read in a suitable manner.
