JPEG Multi-Picture Format (MPO, extension .mpo) is a JPEG-based format for storing multiple images in a single file. It contains two or more JPEG files concatenated together.<ref>{{cite web |url=http://www.cipa.jp/std/documents/e/DC-007_E.pdf |title=Multi-Picture Format |date=2009 |access-date=2015-12-30 |archive-date=2016-04-05 |archive-url=https://web.archive.org/web/20160405200235/http://cipa.jp/std/documents/e/DC-007_E.pdf  }}</ref><ref>{{citation|url=http://www.mtbs3d.com/phpbb/viewtopic.php?f=3&t=4124&start=15|title=MPO2Stereo: Convert Fujifilm MPO files to JPEG stereo pairs|website=Mtbs3d.com|access-date=12 January 2010|archive-date=31 May 2010|archive-url=https://web.archive.org/web/20100531020644/http://www.mtbs3d.com/phpbb/viewtopic.php?f=3&t=4124&start=15|url-status=live}}</ref> It also defines a JPEG APP2 marker segment for image description. Various devices use it to store 3D images, such as [[Fujifilm FinePix Real 3D W1]], [[HTC Evo 3D]], JVC GY-HMZ1U AVCHD/MVC extension camcorder, [[Nintendo 3DS]], [[Panasonic Lumix DMC-TZ20]], [[Panasonic Lumix DMC-TZ30|DMC-TZ30]], [[Panasonic Lumix DMC-TZ60|DMC-TZ60]], DMC-TS4 (FT4), and [[Sony]] DSC-HX7V. Other devices use it to store "preview images" that can be displayed on a TV.

In the last few years, due to the growing use of stereoscopic images, much effort has been spent by the scientific community to develop algorithms for stereoscopic image compression.<ref>{{citation|url=http://iplab.dmi.unict.it/publication/503|title=A new fast matching method for adaptive compression of stereoscopic images|journal=Three-Dimensional Image Processing|volume=9393|pages=93930K|author1=Alessandro Ortis|author2=Sebastiano Battiato|editor1-first=Robert|editor1-last=Sitnik|editor2-first=William|editor2-last=Puech|publisher=SPIE - Three-Dimensional Image Processing, Measurement (3DIPM), and Applications 2015|access-date=30 April 2015|bibcode=2015SPIE.9393E..0KO|year=2015|doi=10.1117/12.2086372|series=Three-Dimensional Image Processing, Measurement (3DIPM), and Applications 2015|s2cid=18879942|archive-date=3 March 2016|archive-url=https://web.archive.org/web/20160303232457/http://iplab.dmi.unict.it/publication/503|url-status=live}}</ref><ref>{{citation |url=http://iplab.dmi.unict.it/publication/49 |title=Adaptive Compression of Stereoscopic Images |author1=Alessandro Ortis |author2=Francesco Rundo |author3=Giuseppe Di Giore |author4=Sebastiano Battiato |publisher=International Conference on Image Analysis and Processing (ICIAP) 2013 |access-date=30 April 2015 |archive-date=3 March 2016 |archive-url=https://web.archive.org/web/20160303205755/http://iplab.dmi.unict.it/publication/49 |url-status=live }}</ref>
