The Joint Bi-level Image Experts Group (JBIG) is a group of experts nominated by national standards bodies and major companies to work to produce standards for bi-level image coding. The "joint" refers to its status as a committee working on both ISO and ITU-T standards. It is one of two sub-groups of ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 1 (ISO/IEC JTC 1/SC 29/WG 1), whose official title is ''Coding of still pictures''.〔(【引用サイトリンク】title=Programme of Work, (Allocated to SC 29/WG 1) )〕〔(【引用サイトリンク】title=JTC 1/SC 29 - Coding of audio, picture, multimedia and hypermedia information )〕 The Joint Bi-level Image Experts Group created the JBIG and JBIG2 standards. The group often meets jointly with the JPEG committee, which typically meets three times annually. ISO/IEC JTC1 SC29 Working Group 1 (working together with ITU-T Study Group 16 – VCEG〔(【引用サイトリンク】title=ITU-T Home : Study Groups : Study Group 16 - Question 6/16 – Visual coding )〕 and previously also with Study Group 8 – SG8〔(【引用サイトリンク】title=ITU-T Study Group 8 (Study Period 1997-2000) )〕) is responsible for both JPEG and JBIG standards.〔(【引用サイトリンク】 title=Joint Photographic Experts Group, JBIG Homepage )〕 It includes two sub-groups: the Joint Photographic Experts Group (JPEG SG) and the Joint Bi-level Image experts Group (JBIG SG).〔〔 In the mid-1980s, both CCITT (now ITU-T) and ISO had standardization groups for image coding: CCITT Study Group (SG) VIII (Telematic Services) and ISO TC97 SC2 WG8 (Coding of Audio and Picture Information). They were historically targeted on image communication. In 1986, it was decided to create the Joint (CCITT/ISO) Photographic Expert Group. In 1988, it was decided to create the Joint (CCITT/ISO) Bi-level Image Group – JBIG.〔 == Published Standards == JBIG have developed following standards, which were published by ISO/IEC and/or ITU-T: Note: The published JBIG2 standard was revised by later amendments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joint Bi-level Image Experts Group」の詳細全文を読む スポンサード リンク
