適用范圍：1 This International Standard specifies the position and dimensions of machine-readable identification numbers on 16 mm, 35 mm and 65 mm motion-picture film. These numbers are intended to be a machine-readable version of the latent image key number. This International Standard also specifies the encoding format to be used for these machine-readable numbers, as well as the area scanned and the spectral characteristics of the scanner. 2 This International Standard also specifies the position, dimensions and content of human-readable identification (key) numbers for use on 16 mm, 35 mm and 65 mm motion-picture films intended for original photography or intermediate printing which also include the machine-readable key number described in 1.1. NOTE These numbers normally are exposed onto the film at the time of manufacture. 3 This International Standard further specifies an area that may be used for optional manufacturer-specific film-type identification information. 4 This International Standard also specifies an area on the film which is not to be exposed by the film manufacturer, thus leaving it available for customer data recording. 5 Finally, this International Standard specifies an optional frame line index mark for 35 mm and 65 mm film.
