ISO/IEC JTC1 SC29 Working Group 1 (working together with ITU-T Study Group 16 – SG16〔(【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 the JPEG and JBIG standards.〔(【引用サイトリンク】 title=Joint Photographic Experts Group, JBIG Homepage )〕 The scope of the organization includes the work of both the Joint Photographic Experts Group and Joint Bi-level Image Experts Group.〔 In April 1983, ISO started to work to add photo quality graphics to text terminals.

The group often meets jointly with the JBIG committee.〔 == Joint Bi-level Image experts Group == The Joint Bi-level Image experts Group (JBIG) is the second sub-group of the same working group (ISO/IEC JTC 1/SC 29/WG 1) as the Joint Photographic Experts Group, which focuses on binary images.〔 They created the JBIG and JBIG2 standard.〔〔 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 Photographic Experts Group」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
