Abstract
Abstract There are provided an image information processing method and an apparatus thereof to process information carried by an electro-magnetic radiation beam by means of a photo-to-photo transducer. An intensity of an image information is adjusted by varying the intensity of an electro-magnetic radiation beam used for reading the information as electro-magnetic radiation beam information, which has been recorded on the transducer as a charge image. The electro-magnetic raidation beam information read out from the transducer is inverted by changing an operating range of a photo-modulation layer which is one of the components of the transducer. Furthermore, the electro-magnetic radiation beam information read out from the transducer is nonlinearly processed.
