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 disclosed a recording/reproducing system comprising an optical system for directing along a path of an electromagnetic radio ray from an object toward a recording medium, and a recording head disposed in the path for generating a charge latent image onto the medium. The feature of the system resides in that the recording head (system) forms the detection region which is not entirely subject to the influence of the electromagnetic radio ray and which is provided in a portion of the charge recording region of the medium, and in that a reproducing system discriminates the polarity of charges or the recording mode of the charge latent image recorded onto the medium by detecting the charges in the dectection region.

摘要： An electromagnetic radiation beam scanning system for scanning an object with an electromagnetic radiation beam. The scanning system comprises first and second beam-narrowing devices which are arranged so as to have elongated light-transmission regions, respectively, and which are overlapped each other so that the light-transmission regions intersect each other. Each of the beam-narrowing devices includes a light modulation layer showing an electro-optic effect, first and second electrodes disposed so as to sandwich the light modulation layer, first and second polarizers disposed so as to sandwich the light modulation layer and a power source for applying voltages to the first and second electrodes. The light modulation layer combined with the polarizers forms the elongated light-transmission region in response to application of the voltages to the first and second electrodes due to the power source so as to produce a narrowed beam when a light beam is incident thereon. The position of each of the light-transmission regions in each of the first and second beam-narrowing devices is arranged to be movable in response to variation of at least one of the application voltages due to the power source.

摘要： There is provided an apparatus for reproducing a charge latent image prerecorded on a recording medium composed of at least a photo-modulation layer and a charge holding layer laminated thereto and holding said charge latent image. The apparatus has two electrodes interposing the recording medium therebetween. The electrodes are connected to each other and one of which is spaced from the recording medium. A reading light is allowed to permeate the photo-modulation layer. The apparatus also has a vibrator which vibrates one of the electrodes to modulate an electric field generated between the electrodes by the charge latent image prerecorded on the recording medium. The reading light is then electro-optically modulated to reproduce the charge latent image.

摘要： A charge latent image is formed on a recording medium in response to information and a reference pattern so that the information and the reference pattern are recorded on the recording medium. During a reproducing process, the information is read out from the recording medium and an information signal representing the readout information is generated. In addition, the reference pattern is read out from the recording medium and a reference signal representing the reference pattern is generated. The information is demodulated from the information signal. The reference signal is used in the demodulation of the information from the information signal.

The image sensing device includes an photoconductive member responsive to the optical image on one surface thereof to produce an charge image corresponding to the optical image on the other surface under a predetermined electric field and a change holding member arranged so that an electrostatic latent image is formed on one surface thereof. The charge holding member is disposed to be opposed relation to the photoconductive member and first and second electrodes are respectively disposed on the photoconductive member and the charge holding member. Also included in the device is a voltage application circuit comprising a change-over switch and a power source so that a voltage of the power source is applicable to the first and second electrodes. The operation of the switch is controlled by a switch control unit so as to allow and interrupt the application of the voltage of the power source to the first and second electrodes. Discharging between the members is developed in response to application of the voltage thereto so that a charge image is formed on the charge holding member in correspondance with the charge image formed on the photoconductive member.
