11、dies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizatio
12、ns, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the I
13、SO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. 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 least 75 % of the
14、member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 17321-1 was prepared by Technical Committee ISO/TC 42, Photography, i
15、n collaboration with ISO/TC 130, Graphic technology.This second edition cancels and replaces the first edition (ISO 17321-1:2006), of which it constitutes a minor revision with the following changes: in 4.3.3.4.2, the typographical error “senor image area” was corrected to “sensor image area”; in B.
16、2.6, a broken link to tools for non-linear optimization has been updated.ISO 17321 consists of the following parts, under the general title Graphic technology and photography Colour characterization of digital still cameras (DSCs): Part 1: Stimuli, metrology and test procedures Part 2: Consideration
17、s for determining scene analysis transforms Technical Reportiv ISO 2012 All rights reservedBS ISO 17321-1:2012ISO 17321-1:2012(E)IntroductionThe spectral responses of the colour analysis channels of digital still cameras (DSCs) do not, in general, match those of a typical human observer, such as def
18、ined by the CIE standard colorimetric observer. Nor do the responses of different DSCs ordinarily match each other. In characterizing DSCs, it is therefore necessary to take account of the DSC spectral sensitivities, illumination, and encoding colour space. This part of ISO 17321 will begin to addre
19、ss these considerations. This part of ISO 17321 defines stimuli (spectral illumination or a colour target), metrology and photographic test procedures for acquiring DSC characterization data. It specifies test procedures for “scenes”, the most general picture taking conditions where metameric colour
20、s and a range of illumination sources are encountered. It also specifies test procedures for hardcopy “originals”, a more narrowly defined picture-taking condition in which the illumination source and the colorants being imaged are pre-defined.ISO 17321 will distinguish among several possible image
21、representations in different colour encodings as depicted in Figure 1 which shows the diagram of a generic image workflow for digital photography.Figure 1 Generic image workflow for digital photographyThe DSC characterizations obtained using this part of ISO 17321 will be applicable to raw (sensor-r
22、eferred) DSC data. Two alternative methods are described for obtaining these characterization data. Method A, the spectral method, uses spectral lights as stimuli for measuring the colour performance of a DSC. Method B, the target method, involves the use of a physical colour test target under speci
23、fic lighting conditions to measure DSC colour performance. Annexes A to C recommend a laboratory set-up for photographing reflection targets, provide target patch selection criteria, and provide a digital still camera metamerism index.

24、2(E)Some operations (colour pixel reconstruction, flare removal, white balancing) can be performed without disqualifying the DSC data as being raw. However, operations that render the image data so that they become output-referred (ready to display or to print) generally do disqualify the data. With
