摘要:
Die Erfindung betrifft eine Filmhaltevorrichtung (11,33,37,61) zum Halten eines intermittierend transportierten Laufbildfilms (71). Die Filmhaltevorrichtung besitzt eine Filmbahn (33) zum Führen des Laufbildfilms sowie eine Sperrgreifereinrichtung (61;61'), die aus einer Freigabestellung in eine Greifstellung bewegt werden kann. In der Greifstellung greift die Sperrgreifereinrichtung in die Transportebene des Laufbildfilms (71) ein, um einen in der Filmbahn (33) geführten Laufbildfilm lagegenau zu fixieren. Für das Eingreifen der Sperrgreifereinrichtung in die Filmtransportebene ist alternativ zu einer Referenzposition (79) wenigstens eine Alternativposition (77) auswählbar.
摘要:
A luminous source apparatus, an image projecting apparatus, and an image projection converting apparatus are provided, which reduce intensity variations in a projected image, or an electronic image obtained through electronization of the projected image. A photosensor detecting the light-emission quantity from a light-emission lamp is preferably set up, m order to regulate the current supplied with the light-emission lamp from a power according to a light-quantity detecting signal from the photosensor, so as to make the light-emission quantity from the light-emission lamp constant. Projected light-quantity onto a movie film can be regulated and an image obtained from a shooting section becomes an image having a good quality with little flicker.

In a film positioning system and method thereof, stable film positioning is accomplished. In the present invention, when a film is fed to a stop position by driving first feeding means and second feeding means synchronizing with each other and then the stop position is determined with the first feeding means or the second feeding means, a fixed tension is applied to the film by the other feeding means.

A lamphouse for a telecine allows the spectral composition of its output to be controlled electronically. A light beam (300) is bounced off mirrors to reduce its infrared content, then passes through three beam splitters (305, 310, 315) which split off the blue, red and green content. The blue, red and green beams pass through electronic shutters (320, 325, 330) and are then reflected off dichroic mirrors (335, 340, 345) to become a single beam (348) again. The spectral content of the single beam is controllable by turning the electronic shutters (335, 340, 345) corresponding to the blue, red and green beams on and off.
摘要:
A film scanner scans a frame of film three times by reciprocating a clapper gate assembly (160) holding the film (50) past a solid state line array sensor (210). Successive scans are in an opposite sense to the previous scan and R,G,B filter wheel (40) is placed in the optical path and advanced for each scan so that separate high resolution R,G and B scan are produced which can be combined to form a high resolution video signal.
