The wor
15、k of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governme
16、ntal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for votin
17、g. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 12222 was prepared by Technical Committee ISO/TC 36, Cinematography. This second edition cancels and replaces the first edition (ISO 12222:1996), clause 2, T

20、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 machin
21、e-readable numbers, as well as the area scanned and the spectral characteristics of the scanner. 1.2 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 orig
22、inal photography or intermediate printing which also include the machine-readable key number described in 1.1. NOTEThese numbers normally are exposed onto the film at the time of manufacture. 1.3 This International Standard further specifies an area that may be used for optional manufacturer-specifi
23、c film-type identification information. 1.4 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. 1.5 Finally, this International Standard specifies an optional frame line index mark
24、for 35 mm and 65 mm films. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties
25、to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

28、aced at regular intervals, typically every 20 perforations for 16 mm film, 64 perforations for 35 mm film and 80 perforations for 65 mm film. For the purposes of this International Standard, the key numbers are latent-image exposed. 3.2 bar edge gbar code that point where the transmittance is halfwa

No latent information shall be placed along the upper edge of the film, as shown in Figur
32、e 1, Figure 2 and Figure 3. This area is reserved for data recording at the time of photography. This identification information is intended to be exposed onto film cut and perforated in accordance with ISO 69, ISO 491 or ISO 3023.

34、e. The film shall be supplied to the user with the lowest number at the outside of the roll unless the sales format of the unit shown states differently. The human-readable key number shall consist of two alphabetic characters and 10 numerical characters. For 16 mm film, this alphanumeric code shall
35、 be separated into three groups of four characters, as shown in Figure 1. For 35 mm and 65 mm film, this alphanumeric code shall be separated into groups of two alphabetic characters and two, four and four digits, separated by spaces, as shown in Figure 2 and Figure 3. 5.1.2 Alphabetic characters Th
36、e first two alphabetic characters of the key number identify the manufacturer and film type. The character set used shall be the normal upper-case letters A through Z. The first alphabetic character shall identify the film manufacturer, according to Table 1. Other letters are reserved for future ass
37、ignment by ISO/TC 36. The second character shall be a film-type identifier. The character is chosen at the discretion of the film manufacturer. Table 1 Manufacturer alphabetic codes 5.1.3 Numerical characters For the 10 numerical characters of the key number, only the digits 0, 1, 2, 3, 4, 5, 6, 7,
38、8 and 9 shall be used, and they shall be in normal counting sequence. It is recommended, although not required, that the “ten thousands” place not be allowed to increment within a single roll of film. 5.2 Human-readable key number specifications applicable to 16 mm film only 5.2.1 Dimensions The hei
39、ght and width of the human-readable key numbers shall be as specified in Figure 4 and Table 2. Note that the height of the first character is less than that of the others to allow for the reference mark specified in 5.2.2. The width of each human-readable character is left to the manufacturers discr
40、etion, but it should be wide enough for good legibility, while still maintaining dimension F. A character height-to-width ratio of 14 : 10 and a space between characters of 2/14 of a character height is recommended.

The frame immediately above the zero-frame reference mark is the one referenced by that key number. Other frames are specified by an offset which is written as (an) additional digit(s) separated from the key number by a plus sign. Figure 5 shows an example of this rule. 5.2.5 Repeat frequency
