摘要： 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.

摘要： There is provided a photosensitive medium for recording a charge latent image, composed of a photo-conductive layer having an electrode and a protective layer at each surface thereof. There is further provided a charge latent image recording method. A photo-conductive layer and a charge holding layer, each having an electrode at a surface thereof, are arranged to face each other through a gap. A predetermined voltage is applied across the photo-conductive layer and the charge holding layer through the electrodes to cause discharge thereacross. At the time, an electro-magnetic wave corresponding to the charge latent image intended to be recorded is emitted to the photo-conductive layer. The impedance of the photo-conductive layer is thus varied to record the charge latent image on the charge holding layer. In the method, the rise time constant of the voltage applied across the electrodes is adjusted to that of the discharge or more, and the potential of the charge latent image is adjusted to a discharge starting voltage or less.
