(I3A)Approved July 17, 2002 American National Standards Institute, Inc.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other cri

Substantial agreement means much more thana simple majority, but not n

11、ional Standard ANSI/I3A IT10.7466-2002.)This I3A standard has been developed in order to meet the industry need for a com-plete, fully documented, publicly available definition of a wide-primary scene-referredextended color-gamut RGB color encoding. This encoding provides a way to repre-sent scene-r

12、eferred images that does not limit the color gamut to those colors capa-ble of being displayed on a CRT monitor, or require the use of negative RGBcolorimetry co-ordinates. An extended color-gamut scene-referred color encoding is particularly desirable forprofessional photography applications. For e

13、xample, colors captured by digital cam-eras, as well as conventional capture devices such as photographic film, may be out-side those that can be represented within the color gamut of a typical monitor or othertypes of output devices. Likewise, scene-referred images will generally have a largerlumin

14、ance dynamic range than output-referred images since they have not beenmodified by a color rendering process to fit the images within the limitations of theoutput media and apply appropriate tone/color reproduction aims. Retaining the un-rendered scene-referred image data has the advantage that it p

15、reserves the option tomake decisions about how a particular image should be rendered. For example, ascene-referred image of a back-lit scene can retain information about both the darkforeground region and the bright background region of the scene. This informationcan be used to make a properly expos

16、ed print of either the foreground region or thebackground region, or alternatively can be used to create an improved image by ren-dering the two regions differently. By using a standard scene-referred extended col-or-gamut color encoding, images can be stored, interchanged and manipulatedwithout res

17、tricting the image to a particular rendering intent or output device. TheReference Input Medium Metric RGB (RIMM RGB) color encoding specified in thisI3A standard meets the needs of these types of applications. An extended dynamicrange version of this color encoding known as Extended Reference Input

18、 MediumMetric RGB (ERIMM RGB) is also specified for use with high-dynamic range inputsources. (E)RIMM RGB is intended to be a companion to the output-referred ROMMRGB color encoding specified in ANSI/I3A IT10.7666-2002. Both color encodingsare based on the same “wide RGB“ color space to facilitate t

19、he development of im-age processing algorithms and simple color rendering transformations to convertscene-referred RIMM RGB images to rendered output-referred ROMM RGB images.Within ISO/TC42, work has begun to develop ISO 22028, “Extended colour encodingfor digital still image storage, manipulation

20、and interchange“. Work on this standardmay progress as part of a new joint project team between ISO/TC42 and IEC/TC100that is being set up in accordance with JTAB Decision 3/2000. After an internationalstandard specifying RIMM-RGB is published, it is anticipated that this I3A standardwill be withdra
