Abstract:
To be able to scan the sprocket holes of a film with improved precision by means of a film scanner, in which a correction signal is generated for compensating picture steadiness errors, it is proposed that the light source generates light in the infrared range, and that the scanning sensor(s) is (are) sensitive in the infrared range.
