Abstract: To provide an image reading apparatus which is capable of easily and quickly specifying a frame of a transparency original for which image reading is desired from the transparency original having a plurality of frames and of image reading with high accuracy at the time of final reading of a specified image. The image reading apparatus comprises: a carrier member holding a film-shaped transparency original which has a plurality of frames; an illuminating means illuminating the transparency original; and an image reading means reading image data of the transparency original illuminated by the illuminating means, in which when the image data is read in previewing, the carrier member is moved by a carrier moving means, and when final image reading of the image data is effected, the carrier member is moved by moving a carrier frame having the carrier moving means. The image data which has been read is outputted to an image display device connected to the image reading apparatus.

Abstract: A device for displaying photographic images by reading image data recorded on a film and displaying them on a display means, wherein the kind of the film is discriminated, at least either one of the number of frames displayed on a screen of the display means or the reading resolution of the image reader means is variably determined depending upon the kind of the film that is discriminated, and the images are displayed on the screen of the display means depending upon the determination by the determination means. The images of frames of a number determined depending upon the kind of the film are efficiently displayed on the screen of the display means and/or the images are displayed maintaining a proper resolution depending upon the kind of the film by varying the reading resolution of the image reader means.

Abstract: Provision is made of a carrier for holding a piece film cut every after several frames and a carrier for holding a long wound film contained in a cartridge and having a motor for frame-feeding. When the carrier is loaded, the carrier is driven at a high speed by a first stepping motor and is driven to a predetermined position, to optically detect whether the carrier is for holding the piece film or for holding the long wound film. When the carrier is for holding the piece film, the carrier is driven at a high speed by the first stepping motor and is prescanned. When the carrier is for holding the long wound film, the carrier is driven by a second stepping motor and is prescanned. In the main scanning, both of the carriers are driven by the second stepping motor at a low speed, so that image is read maintaining a high resolution.

Abstract: A film scanner includes: a film carrier having, an aperture for image reading, a film conveyor for conveying a film on which image information in each frame has been recorded, to the aperture one frame by one frame of the film, and a communication device for receiving a control signal to control the film conveyor; an image reader for optically reading the recorded image information on the film; a controller for generating the control signal; and a first outputting device connected with the communication device for outputting the control signal to the film carrier.

Abstract: In an apparatus for reproducing a photographed image on each frame of a developed photographic roll film, wherein each frame includes an image region on which the photographed image is provided and a memory region in which information with regard to the photographed image is stored, an information reader for reading the information stored in the memory region; a processing circuit for processing image signals photoelectrically obtained by an image reader on the bases of the information; and the processed image signals are displayed on the screen.

Abstract: The invention provides a tripod for use with a camera by which the camera can be set horizontally without any difficulty. The tripod includes a supporting base for supporting a camera thereon through screw mechanism. On the lower surface of the base is provided a central leg composed of a pliantly bendable rod like member. On both the sides of the central leg are symmetrically provided a pair of side legs, each of which is adapted to pivotally open in outwardly slanting direction to a stop position and is shorter than the central leg.

Abstract: A film feeding control device for a camera in which film perforations are arranged so as to pass through a detecting section of a photointerrupter during film feeding, which detects the presence of perforations by comparing an output signal from the photointerrupter when the perforations pass through the detecting section with a predetermined threshold limit value and which detects film feeding conditions according to the variation of the output signal, characterized in that the device includes: (i) calculating means for calculating an average value from maximum and minimum values of the output signal from the photointerrupter; (ii) judging means for establishing the average value as the threshold limit value and for discriminating the film feeding condition by comparing the output signal from the photointerrupter with the threshold limit value; and (iii) controlling means for controlling the feed of film according to the judged result by the judging means.

Abstract: In a process for the production of a high-hardness boron nitride film by vacuum-depositing a boron component on a substrate from a boron-containing vacuum deposition source and simultaneously irradiating the substrate with an ion seed comprising at least nitrogen from an ion-generating source, if the atomic ratio (B/N) between boron and nitrogen supplied from the vacuum deposition source and the ion seed is adjusted within a range of from 4 to 25, the ion acceleration energy of the ion seed is adjusted to 5 to 100 KeV per atom of the ion seed and vacuum deposition and irradiation are carried out in an atmosphere of a nitrogen atom or nitrogen compound activated at an energy level lower than that of the ion seed, the hardness and quality of the film are highly improved. Furthermore, if a negative bias voltage is applied to the substrate at the vacuum deposition and irradiation with the seed ion, the film-forming speed can be increased and the hardness and quality of the film are further improved.
