The work of preparing International Standards is normally carried out through isO technica committees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeenestablishedhas liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnica Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. This second edition cancels and replaces the first edition (isO 6328:1982), which has been technically revised. In this revision, the description of the process of evaluating images has been expanded. The specifications of the resolving power camera's objectives have been altered slightly, and the illustration of a resolving-power camera include the target. This second edition also contains many other changes, most of which were made for the sake of clarity of understanding. Among these changes is a clarification of part of the scope. The definitions have also been expanded; some terms have been substituted for others in order for their usage to be more consistent and their power target" replaces “test chart". Other terms introduced or clearly defined include “target polarity", “limiting element" and"IsO resolving power". Annex A of this International Standard is for information only. @ ISO 2000 - All rights reserved ISO 6328:2000(E) Introduction observable when recorded on the material. It combines the effects of modulation transfer function, graininess and assessment of quality. The method is particularly useful for appraising materials that will be viewed at high described by a single factor. This is particularly the case for low-contrast continuous-tone products.
