28、ing all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standar
29、ds, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this prepara
30、tory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organiza
31、tions. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of
32、recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation
33、by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regiona
34、l publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this public
35、ation. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, o
36、r for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the corre
37、ct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61966-9 has been prepared by
38、 IEC technical committee 100: Audio, video and multimedia systems and equipment. This bilingual version (2013-03) corresponds to the monolingual English version, published in 2003-11. This second edition cancels and replaces the first edition published in 2000. This edition includes the following si
39、gnificant technical changes from the previous edition. a) In the light of issuing IEC 61966-2-2, the relevant reference IEC 61966-2-1 in Annex C has been replaced by IEC 61966-2-2 together with sRGB by scRGB. b) The previous Annex C has been replaced by the new Annex C where the previous Figure C.1
40、has been deleted. 61966-9 IEC:2003 5 The text of this standard was submitted to the national committees for voting under the Fast Track Procedure as the following documents: CDV Report on voting 100/666/CDV 100/722/RVC Full information on the voting for the approval of this standard can be found in

46、MENT Part 9: Digital cameras 1 Scope This part of IEC 61966 is applicable to the assessment of colour reproduction of digital cameras used in open computer systems and similar applications. A series of methods and parameters for colour measurements and management for use in multimedia systems and eq
47、uipment is applicable to the assessment of colour reproduction. This standard deals with digital cameras to capture colour still images and moving images for use in multimedia applications. The methods of measurement standardized in this standard are designed to make possible the objective performan
48、ce assessment and characterization of the colour reproduction of digital cameras which can capture colour still and moving images, and output colour information corresponding to red green blue digital image data. The measured results are intended to be used for the purpose of colour management in mu
49、ltimedia systems, typically in the Internet. This standard defines test charts, measurement conditions and methods of measurement, so as to make possible the colour management in open multimedia systems and comprehensive comparison of the results of measurements for assessment of digital cameras. Colour control within digital cameras is outwith the scope
