14、2-2000 iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject fo

15、r which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on

16、all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO

17、10198 was prepared by Technical Committee ISO/TC171, Micrographics and optical memories for document and image recording, storage and use.

25、d, the definitions given in ISO6196 and the following definition apply. 3.1 synchronization of a rotary camera timed movement of documents and microfilm in relation to the reduction ratio to record an accurate image on the film 4 Operating procedures 4.1 Image format The camera shall record images a

26、ccording to one or more of the formats specified in ISO6199 (simplex, duplex, duo or duo-duplex). 4.2 Documents 4.2.1 Document width The camera manufacturer shall state the maximum document width that can be filmed across the width of the film. This dimension depends on camera throat width, filming

27、format, reduction ratio and whether coding is used (for guidance, seeTable A.1 and Table A.2). 4.2.2 Other characteristics The camera manufacturer shall provide the minimum document length that can be photographed parallel to the axis of the film. Thisdimension depends on the characteristics of the

28、mechanical transport device. Normally, there is no maximum length in this direction. The camera manufacturer shall provide the specifications of the paper to be used with the camera, such as the weight and thickness, in the accompanying operators manual. 4.3 Rawstock film The camera shall use16mm ra

29、wstock microfilm as specified in ISO6148 and spools as specified in ISO1116. The manufacturer shall state the acceptable thickness of film in the operators manual. 1) To be published.ISO10198:1994(E) 2 BSI 02-2000 5 Mechanical characteristics 5.1 Synchronization of film and document The camera shall

30、 keep the film and document in synchronization during the filming, in order to meet image quality specification. 5.2 Positioning of documents The camera shall be equipped with a guiding device to facilitate the entry of the document and their transport within the camera. 5.3 Document feeding Usually

31、, documents are fed face up with heading forward and oriented according to the width of the throat. Documents can be fed into the cameras by hand or by automatic feeder. Automatic document feeders shall separate papers, sheet by sheet, for feeding into the camera, provided that the documents are sim

32、ilar in weight and thickness. 5.4 Document protection If the transport mechanism fails, it shall be possible to remove the document without irreparable damage. 5.5 Optional features The camera may be equipped with the following features: ability to record in duplex, duo or duo-duplex mode; dual film

33、 (magazines); removable camera heads; an exposure signal, indicating shutter opening and/or film transport operation; an automatic document counter/recorder capable of being reset to zero; indicators for lamp failure; information coding devices imprinters, cancelling devices, date and time stamps, f

34、ilm image marks (blips), frame numbering devices, etc.; devices for indicating the length of film available and the film movement; advance warning before running out of film; method to prevent or detect the simultaneous entry of more than one document at a time; automatic stop upon machine malfuncti

35、on. 5.6 Document delivery tray The documents, once microfilmed, should be delivered in their original order. The delivery tray shall be visible and easily accessible to the operator. 5.7 Noise emission The noise emitted by the camera, measured inaccordance with ISO7779, shall not exceed70dB(A) durin

36、g normal operation. Impulsenoise of equipment shall not exceed75dB. 5.8 Temperature The temperature of camera surfaces shall not exceed the values given in Table 1 after the camera has been operated in an area with an ambient temperature of23 C 2 C for1h. 6 Optical characteristics 6.1 Exposure Light

37、ing, lenses, and mirrors shall be adjusted so that when a full-size sheet of paper with uniform reflectance is filmed, the image density shall meet the following requirements: a) When measured in accordance with ISO5-2 and ISO5-3, the background density of a sheet of white paper with80% reflectance

38、shall be within the range0,8 to1,5 density units, this provides enough exposure latitude for (coloured) documents with a reflectance density as low as50%. b) When measured in accordance with ISO5-2 and ISO5-3, the difference in background density between any two points on the document shall be no gr

39、eater than0,3 density units. c) When recording the same type of document thebackground density from image to image from start of roll to end of roll shall not vary by more than0,3density units when measured in anon-information area on the centreline in the direction of travel of the document image.

40、This also applies to images in the duplex format. d) If both front and back of the documents are filmed then the background density shall not vary by more than0,3from front to back provided they are the same colour. e) When automatic exposure control is available and used, it shall respond in such a

41、 manner as to minimize underexposure of the leading and trailing edges of the document. f) A shutter shall be provided to protect the film from unwanted exposure when no document is being filmed. g) The camera shall be light tight to prevent film fog during extended periods of nonoperation. NOTE 1If

42、 a roll is partially exposed, completed later and then processed, latent image fade could cause density variations larger than0,2 from one end of the roll to the other.ISO10198:1994(E) BSI 02-2000 3 Table 1 Camera part temperature 6.2 Image quality A maximum variation of four test chart groups ofcha

43、racters of ISO test chart No.1 or test chart patterns of ISO test chart No.2 is allowed either within one document image or between any two images. 7 Alternative components If alternative components are available, e.g.camera heads, document feeders, etc., the user should not need tools to change or

44、remove them. 8 Climatic conditions The camera shall be capable of normal operation at temperatures within the range15 C to32 C and relative humidity within the range20% to75%. 9 Electrical supply The camera shall meet the voltage and frequency specifications of the country where it will be used. Ifp

45、ower supply voltage has a wide variation, a constant voltage device can be required. Such a device is usually subject to the camera manufacturers approval. 10 Electrical safety The camera shall meet the requirements of IEC950 for electrical safety. 11 Controls All operator controls shall be easy to

46、access and operate. 12 Markings The information below shall be legibly displayed on the camera in a durable manner: a) manufacturers or suppliers name or trademark; b) model or type of camera; c) serial number; d) nominal voltage, wattage and frequency of theelectricity supply in hertz; e) controls

47、marked in the language acceptable to the country in which the camera will be sold or in symbols specified in IEC417; f) reduction ratio; g) lamp identification specifications shall be in the area of the lamp housings; h) fuse specifications shall be adjacent to the fuse holder. 13 Operator manual Th

48、e camera shall be delivered with a manual containing operation and maintenance instructions written in a language acceptable to the country in which the camera will be used. A list of commonly required replacement parts that includes identification numbers, if used, shall accompany orbe part of the

49、operator manual.
