6、age Mark (Blip) Used in Image Mark Retrieval Systems, This standard has been revised by the Micrographic Encoding Committee of the Association for Information and Image Management to include multisize image marks, their dimensions, location, and general use. This standard specifically describes the

7、characteristics of the image mark (formerly known as blip mark) on 16 mm film. It defines the use of the image marks in retrieval, and discusses the film control codes in the appendix. There are currently only two film control codes in general com- mercial use. Listed are the general characteristics

8、 but not included are the specific codes or their control which is available from the manufacturers. Suggestions for improvement gained from the use of this standard are welcome. They should be sent to the Chairman, AIIM Standards Board, Association for Infor- mation and Image Management, ll00 Wayne

27、ormat, orientation and placement of document images can be obtained from ANSIIAIIM MS14-1987. 4.2 Image Mark Location in Relation to Image Area. The preferred location for the image mark, as shown in Figure 4, shall be such that its leading edge shall coin- cide with the document image leading edge

28、within a tolerance of -0.00 mm and +0.26 mm (3-0.010 inch). The permissible location for the image mark, as shown in Figure 4, may range from the leading edge to the trailing edge of the document image. Where required, multisize image marks may extend beyond the image trailing edge, providing the im

29、age mark leading edge coincides with the document image leading edge as shown in Figure 4. The distances from the image leading edge, the image trailing edge, or document image center line to the image mark leading edge shall be uniform throughout the roll of film within the tolerance of f.13 mm (+0

30、.005 inches) (see LEADING END W Figure 3. Channel Identication Figure 5 for example). 4.3 Spacing. The distance between the trailing and leading edges of two consecutive image marks shall be 0.69 mm (0.027 inches) minimum (see Figure 2 for example). 5. Dimensions of Image Mark 5.1 Length, Single Siz

31、e. The minimum length of the single size image mark shall be 0.61 mm (0.024 inches) as shown in Table 1. The maximum length of the image mark shall be half the size of the document image or designated im- age area, whichever is greater, up to a maximum of 7.87 mm (0.310 inches). In cases where half

32、the length of the document image is less than 0.61 mm (0.024 inches), the minimum image mark length shall be 0.61 mm (0.024 inches). 5.2 Lengt., Multisie. The minimum anu maximum lengths of small, medium, and large image marks shall be as shown in Figure 2 and Table 1. 5.3 Height. The image mark hei

33、ght shall be at least 1.14 mm (0.045 inches) when measured across the film width and shall extend from a point that is a maximum of 1.02 mm (0.040 inches) to a point that is a minimum of 1.86 mm (0.074 inches) from the bottom (or. top) edge(s) of 2 AIIM MS8 88 m 3032348 0000558 7 m Preferred locatio

40、t of the Standard for Informa- tion and Image Management-Image Mark (Blip) Used in Image Mark Retrieval Systems, ANSUAIIM MS8-1988.) 1. General Film control codes are being used in some readers to veri the roll identification, set reader parameters, and provide information relative to both the image

41、s on the rol and reader set up. A film control code is a machine readable code used to identi the film information and control, or modify, retrieval terminal operation. Film control code consists of a start code, data code, and stop code encoded on film as various combinations of alternate marks and

42、 spaces. 2. Code Characteristics 2.1 Start Codes. Start codes should consist of one or two very large image marks, greater than 8.7 mm (0.38 inches), with a space separation equal or greater than a small im- age mark. 2.2 Stop Codes. Stop codes should consist of one or two very large image marks gre

43、ater than 8.7 mm (0.38 inches), with a prior space separation equal or greater than a small image mark. 2.3 Data Code. The data code shall be placed between the start and stop codes and should consist of marks and spaces whose length is the same as small, medium, and large image marks. 2.4 Code Mark

44、 Width. Code mark width across the film should be the same as image mark width, see Figure 2 and Table 1. 2.5 Code Mark Density. The density and measurement criteria should be the same as for image marks, see Figure 6. 2.6 Code Polarity. The polarity of the code marks should be the same as that of t

45、he image marks. 2.7 Code Channel. The channels reserved for film con- trol code should extend 2.16 mm (0.085 inches) from each edge of the film and should be the same as image mark channels, see Figure 2 and Table 1. 3. Code Sequence 3.1 General. In Channel A, when the film is moved for- ward, the s

46、tart code should be first followed by the data code, then followed by the stop code. In Channel B, when the film is moved forward in the reader, the sequence should be reversed with the stop code first, foilowed by the data code, then followed by the start code. 3.2 Retrieval Set Up Code. When used,

47、 the retrieval set up code may contain information required to set reader search parameters: to verify film roll number, to set the search program number, and/or to set other parameters relative to the roll identification, image mark polarity, and image position offset. 3.3 Image Address Code. When

48、used, the image address code may contain information required to set reader ad- dress registers. 4. Splices When used, a splice should not conflict with the dimensions of the film control code or image marks. NOTE: Colored splices, including silver metallic, opaque gray, and white may confuse the image counting sensor. 5 AIIM MSB BB m 1012348 0000561 7 m ANSI/AIIM MS8-1988 by Association for Information and Image Management 1100 Wayne Avenue, Suite 1100 Silver Spring, MD 20910 3011587-8202 ISBN 0-89258-126-3 Printed in the United States of America
