Abstract
A telecine scanner, with which the horizontal picture steadiness errors are reduced by the film guidance in the area of the film gate 5, includes a first guiding element 11 supporting one of the longitudinal edges of the film 4 at at least two points in the film gate 5 in the area of the radiation path 6. In addition, two guiding elements 12 are provided, which are spaced substantially centrically apart from the first guiding element 11 and engage the other longitudinal edge of the film 4.
Claims10
A telecine scanner having a light source and an opto-electronic sensor, in which film is transported in a radiation path between the light source and the opto-electronic sensor and is guided transversely to the transport direction, characterized in that said telecine scanner comprises at least a first guiding element for contacting one of the longitudinal edges of the film at least at two distinct non-continuous points in the area of the radiation path.
A telecine scanner, in which the film is transported in the radiation path between a light source and an optoelectronic sensor and is guided transversely to the transport direction, wherein a first guiding element is configured to contact an outer longitudinal edge of the film in the area of the radiation path and is concave shaped with respect to said outer longitudinal edge of the film.
