ABSTRACT:
An image read-out apparatus includes a photoelectrical converting element whose spectral absorption peak only for green (G) light among light of three colors, red (R), green (G) and blue (B), agrees with the spectral absorption peak for green (G) light of a color photographic paper to be used for reproducing a color image recorded on a negative film. According to the thus constituted image read-out apparatus, it is possible to read out the color image recorded on the negative film or the reversal film and convert so-obtained image data to digital signals so as to enable reproduction of a color image having the same tone as that reproduced on the color photographic paper by a conventional method.
