Abstract
The present invention teaches an improved parallel telecine for converting a plurality of recorded images or frames of film, defined by a first and a second set of frames of film, to a digital data stream. The improved telecine comprises a plurality of image transfer or digitizing systems for respectively digitizing each of the recorded images or frames of film or groupings of frames of film. Each image transfer and digitizing system comprises an illuminator system for illuminating the respective frames or groupings of frames, and a camera system for converting the image of the respective frame or groupings of frames into a digital data stream. Each camera sensor additionally comprises a position sensor for detecting a first and a second pair of edges on a coordinated positional tag at the edge of the film frame. Further, each camera system comprises an aligning mechanism for aligning each camera system in response to the set of edges of the respective coordinated position tag detected by the position sensor.
