The best full description of JPEG is the textbook “JPEG Still Image Data Compression
Standard” by William B. Pennebaker and Joan L. Mitchell, published by Van Nostrand
Reinhold, 1993, ISBN 0-442-01272-1. Price US$59.95, 638 pp.
The book includes the complete text of the ISO JPEG standards (DIS 10918-1 and draft
DIS 10918-2). This is by far the most complete exposition of JPEG in existence, and we
highly recommend it.
The JPEG standard itself is not available electronically; you must order a paper copy
through ISO or ITU. (Unless you feel a need to own a certified official copy, we
recommend buying the Pennebaker and Mitchell book instead; it’s much cheaper and
includes a great deal of useful explanatory material.) In the USA, copies of the standard
may be ordered from ANSI Sales at (212) 642-4900, or from Global Engineering
Documents at (800) 854-7179. (ANSI doesn’t take credit card orders, but Global does.)
It’s not cheap: as of 1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus
7% shipping/handling. The standard is divided into two parts, Part 1 being the actual
specification, while Part 2 covers compliance testing methods. Part 1 is titled “Digital
Compression and Coding of Continuous-tone Still Images, Part 1: Requirements and
guidelines” and has document numbers ISO/IEC IS 10918-1, ITU-T T.81. Part 2 is titled
“Digital Compression and Coding of Continuous-tone Still Images, Part 2: Compliance
testing” and has document numbers ISO/IEC IS 10918-2, ITU-T T.83.
Some extensions to the original JPEG standard are defi ned in JPEG Part 3, a newer ISO
standard numbered ISO/IEC IS 10918-3 and ITU-T T.84. IJG currently does not support
any Part 3 extensions.
The JPEG standard does not specify all details of an interchangeable fi le format. For the
omitted details we follow the “JFIF” conventions, revision 1.02. A copy of the JFIF spec
