Abstract
An image reading method which can achieve highly accurate image reading with no color balance lost regardless of the type of recording media, that is, whether a film is a negative film or a reversal film, and thus is able to obtain in a stable manner a reproduced image of higher quality having excellent color balance and density balance. A reading light beam is irradiated on a transparent-type original, the transmitted light of the transparent-type original is separated into the three primary colors and is read by means of an photoelectric transducer device. If the transparent-type original is a negative film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made respectively in the three primary colors independently of one another and, if the transparent-type original is a reversal film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made uniformly in all of the three primary colors.
