3-2-2 Standards for photo recording on card
The DZ-MV350E records photos on SD memory card or MultiMediaCard, conforming to Exif and the
DCF standard. The DZ-MV350E also supports DPOF to facilitate printing of photos recorded on SD
memory card or MultiMediaCard.
(1) Exif (Exchangeable image file format)
Exif is a file format based on JPEG, and is used for recording photos on digital cameras.
Almost all devices that handle photos, such as digital cameras, use high-compression and high-
quality JPEG: To apply JPEG, the basic photo technique, to devices, the file format, etc., used must
be specified. To meet this requirement, Exif was established by JEIDA
Exif has also been adopted for storage media other than SD memory card and MultiMediaCard.
(2) DCF (Design rule for Camera File system) standard
The DCF standard further strictly specifies the Exif specifications in order to enhance compatibility
between various makers and models of digital cameras. It clearly defines the storage names of JPEG
files and folders conforming to Exif, along with additional information, such as recording date,
recording device, etc.
The widespread use of digital cameras has increased the need for direct exchange of images between
devices, including playback of recorded images on another camera or cameras made by other
companies, direct image output on printers, etc.: To meet this demand, the DCF standard was
established by JEIDA

memory card and MultiMediaCard.
Almost all digital cameras conform to the DCF standard, which makes it a de facto standard of
digital camera.
*1: JEIDA stands for Japan Electronic Industry Development Association. JEIDA merged with EIAJ
(Electronic Industries Association of Japan), and the Japan Electronics and Information Technology
Industries Association (JEITA) was formed.
(3) DPOF (Digital Print Order Format)
DPOF included in card navigation functions of DZ-MV350E allows user to record print information
along with recorded photos, such as the selection of recorded photos to be printed and specification
of number of prints, on SD memory card or MultiMediaCard.
The print information thus stored on card means user does not need to select scenes and specify the
number of prints later at photo lab or on home-use printer, thereby facilitating printing.
The DPOF standard was jointly proposed by Cannon, Kodak, FUJIFILM and Matsushita in 1998, so
that photos recorded on compact memory card could easily be output. DPOF also conforms to
storage media other than SD memory card and MultiMediaCard, and is accepted by numerous
companies, including Hitachi.
. The DCF standard can also be adapted to storage media other than SD
