Abstract: Apparatus for automatic control of an image storage device. The image storage device, of the type employing a liquid crystal, is utilized in an intermediate processing step during electrostatographic reproduction of the image. An automatic sequence of voltages and illuminations are applied to the image storage device for erasing previously stored images and for preparing the device for storage of an image. The stored image can be applied to a photoreceptor element of an electrostatographic machine for reproduction of the image. The liquid crystal image storage device can be utilized in conjunction with apparatus for displaying signal encoded data. The display of the signal encoded data can be in a format inconvenient for direct application to the photoreceptor, the image storage device serving as a buffer memory for the image. The stored image can be utilized in conjunction with the electrostatographic machine to provide single or multiple copies of the image.

Abstract: In a telecine equipment of the flying spot cathode-ray tube type with an oscillatory mirror, markers associated with the frames of a film are illuminated with a light spot of small dimensions, which substantially follows the motion of the marker associated with the frame being scanned. This is obtained by means of a small fixed light source, which is used for scanning the path followed by the marker associated with the film frame being scanned, using the same optical channel as for the frame scanning. This same optical channel, used in the reverse direction by means of a fixed mirror located behind the film, forms the image of the illuminated marker.

Abstract: A microform data acquisition processing and storage system in which data is fed from a computer, tape or cards to a cathode ray tube from whence an image produced on the tube is projected onto a photographic film or alternatively by means of an optical switching device an image of a document located on a document platen within the apparatus can be projected on to the same film without changing the film; the cathode ray tube is provided with a coating having a spectral peak between 500 and 600 nm so as to match the spectral peak of the image on the platen.

Abstract: A cathode ray tube pickup device comprises a photosensitive medium having a dielectric layer, a photoconductive layer and conductive layer, a charger for uniformly charging the surface of the photosensitive medium, a discharger for uniformly discharging the charged surface of the photosensitive medium, an optical fiber tube closely spaced from the surface of the photosensitive medium to effect negative image application thereon, and developing means for developing the surface of the photosensitive medium with a toner opposite in polarity to the charge in said surface.

Abstract: A camera for selectively filming at least two separate types of input images through at least one first and second object lens. Each first object lens is mounted on a part rotatable support which is in turn mounted on a rotatable lens carrier. Also mounted on the support are optical deflectors arranged to direct the image of a second object on to the film. In an alternative embodiment the second object lenses and deflectors are mounted on separate slides.

Abstract: An apparatus for automatically issuing an identification card, such as a commutation ticket, airline ticket, credit card, driver's license or the like, which has information forming means having an information storage device for electromagnetically storing a coded information to be described on a web of paper to provide the identification card, a keyboard arrangement having a plurality of keys corresponding to the contents stored in the information storage device, a control device for selecting items from among the contents stored in the information storage device by operating the keyboard arrangement, and an information compiling device for compiling all of the coded information selected by the keyboard arrangement into a video signal information, a copying unit including a photoreceptor drum having the outer peripheral surface adapted to bear a latent image and an optical fiber tube which converts the video signal information into rays of light carrying the respective images of the coded information.

Abstract: An optical picture recording system is constructed such that the lens is a linear lens, and the linear lens or the cathode ray tube is moved so as to confront the electron beam from the cathode ray tube with the linear lens at all times while, when recording one frame, the recording paper is moved in synchronism with movement of the linear lens or the cathode ray tube.

Abstract: An original bears a pictorial image, or the like. The original is illuminated with first and second light and the image on the original is projected onto a copy carrier. The spatial variation of the intensity of the first light after the first light has been modulated in intensity by the image on the original is detected. The contrast of the image projected onto the copy carrier compared to the contrast of the image on the original is changed by changing the spatial variation of the second light in dependence upon the detected spatial variation of the intensity of the modulated first light.

Abstract: To prevent a picture of cathode-ray tube, which picture is projected through an optical lens system from being imaged with a deformed shape on a flat plane because of the curved phosphor screen of cathode-ray tube, an optical lens system is provided having imaging characteristics such that the central portion of an image formed thereby is convex toward the optical lens system.

Abstract: An apparatus in which a charged photoconductive member is exposed to a light image of an original document. An array of solid state light emitters are employed to illuminate the original document. The light image of the original document is projected onto the charged photoconductive member to record thereon an electrostatic latent image.

Abstract: A film coated with a dispersion of an N-vinyl compound, an organic halogen compound and a sensitizer in gelatin is preheated at 60.degree.-120.degree.C before an imagewise exposure to sensitize the film and to destroy fog-nuclei. After the imagewise exposure the film is subjected to a red light flood exposure for intensifying latent image, heating for development and flood light exposure for fixing to give a negative image of high contrast. The preheating may be applied to a film once exposed to extinguish the resulting latent image and thereby to be subjected to another exposure.

Abstract: A method and apparatus for reproducing black and white and color copy having improved contrast of highlight and shadow areas of the copy by recording an optically-produced main image on a light-sensitive emulsion, directing the light emanating therefrom via television camera and electronically inverting the same and sending this signal through a video monitor having contrast and brightness control, and projecting the secondary negative image therefrom onto the light-sensitive emulsion in register with the main positive image.
