摘要： A color imaging system for use as an electronic still camera, for example, includes a color separator for separating the optical image of a subject from a lens into a plurality of different color images, an optical shutter selectively openable for transmitting the optical image of the subject to the color separator, a photoconductive layer for converting the different color images into respective electric charge images, and an information recording medium for recording images corresponding to the electric charge images under an electric field developed between the photoconductive layer and the information recording medium. The timing with which the optical shutter is opened and the timing with which the electric field is generated by the power supply, are controlled by a control unit depending on imaging conditions selected by the user. The color imaging system also has an optical viewfinder for allowing the user to visually observe the optical image of the subject introduced by the lens.

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.

摘要： Time sequential information is written to a first light-to-light conversion element, and the thus-written time sequential information is thereafter written from the first light-to-light conversion element to a second light-to-light conversion element in the form of two-dimensional information. With this arrangement, the time sequential information can be converted with high resolution to the two-dimensional information in real time operation without involving a brightness gradient or shading.
