    摘要: An image conversion apparatus for converting an image recorded on an original into an electrical signal upon reception of illumination light (7) transmitted through the original (6), includes a moving device (2) for mechanically moving the original (6) while holding (5) the original, an optical device (3) for focusing the illumination light transmitted through the original (6) on a focal plane as an image, and an image sensor device (4) for converting the image focused on the focal plane into an electrical signal. The moving device and the optical device share a single base (1), and a shielding device (1a) for preventing a lubricant from being scattered from the moving device to the optical device is formed between the moving device and the optical device.

    摘要: Apparatus for the reproduction of video signals via an intermediate cine film includes a video signal source (1) and a marker generator (5) for marking the video signals. The marked signals are raecorded via a film recorder (9) onto a cine film (11) for archiving. Regeneration of the original video signal from the cine film (11) includes removing the marking from the film (11) using a scanner (33), a marker detector (39) and comparator (46) in order to provide unmarked signals for further broadcast, or the like.

    摘要: In a method of converting on optical signal into an electronic video signal by means of cathode ray tube ('CRT') scanning means (42), each image is scanned in a plurality of scanning operations with each scanning operation using a different area (32,34) of the screen of the CRT scanning means and the signals resulting from the plurality of scanning operations are combined to provide the electronic video signal. Light from the CRT scanning means is passed through deflection means (48) operable to deflect light from respective ones of the plurality of different areas (32,34) of the screen of the CRT scanning means (42) along the same path into an objective lens so that the same area of a film gate positioned in the optical path beyond the objective lens is scanned in each scanning operation. The output of the CRT scanning means (42) is monitored by means of a photoelectric device operable to provide an output signal when a blemish is detected on the screen of the CRT scanning means. The output signal is applied to an analogue-to-digital converter used to process the electronic video signal to cause the video signal level immediately prior to detection of the blemish to be maintained while the blemish persists.

    摘要: Es wird eine Vorrichtung zur punktweisen Abtastung einer Bildvorlage, insbesondere eines Diapositivs oder eines Super-8-Films, für deren Wiedergabe in Fernsehgeräten angegeben, die ein angetriebenes Schlitzblendensystem mit zwei in parallelen Ebenen relativ zueinander bewegtem Schtitzblenden aufweist. Zur konstruktiv und fertigungstechnüsch wesenlich einfacheren Gestaltung der Abtastvorrichtung bei gleichzeitiger Volumenreduzierung für deren Unterbringung ist vorgesehen, daß die Schlitzblenden (11, 12) zumindest im Bereich der Bildvorlage (20) sich gegeneinander in gegensinniger Bewegungsrichtung verschieben und die Schlitze (15, 16) in den beiden Schlitzblenden gegenemander und in die jeweilige Bewegungsrichtung (37, 338) geneigt ausgerichtet sind. Dabei wird mittels der einen, ersten Schlitzblende (11) die nach Fernsehnorn erforderliche abzutastende Zeilenzahl n der Bildvorlage (20) und mittels deranderen, zweiten Schlitzblende (12) die nach Fernsehnorm erforderliche Bildfrequenz bestimmt.

    摘要: A film scanner (200, 300) includes a specular surface (240, 340) for changing a path and a direction of lights for focusing an image, which is filmed on a film, on a sensing module (250, 350). With such a disposition, a height of the film scanner (200, 300) is shortened, and a volume of the film scanner (200, 300) is shortened as a result. The film scanner (200, 300) is also burnt with a driver program on a circuit board, which implements or carries an image processing module (270, 370), so that the film scanner (200, 300) is capable of scanning the image filmed on the film without being connected to a computer, and conveniences in usage and carry of the film scanner (200, 300) is introduced as a result.
