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.
