9、tem for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees c
10、ollaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Stand
11、ards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publicatio

15、8 SWG “Test chart reproduction“ at BAM, Berlin on November, 1999. We actually showed three kinds of test chart as an Asian version and compared some measured image quality of them with DIN test charts. Although these is no published test chart in full agreement with ISO/lEC 15775 not yet now, we str
16、ongly feel to need the improvement on the current components in test charts for the better application of the current standard and the future standards. N1. Reference 1.

Outlines of Improvement We have been continuing to improve the Asian version. To agree the Asian version with the current standard, we need to amend the relating parts of the
18、 current standard. We have introduced two kinds of requirements (i.e. optional contents in the test charts and reproduction methods of the test charts) in these charts. N2-1.The requirements for amendments of the standard texts are mainly as follows: T3: achromatic test chart 1. Optional adoption of
19、 2 mm diameter center circles for Siemens-Stars in C1 2. Minimum L* value of 16 equidistant gray steps is 18.0 3. Optional change from “Landolt-ring“ to “lSO words“ in C4 4. Optional limitation of maximum spatial frequency, 60 lpi in raster lines in C5 5. Optional limitation of maximum spatial frequ
