Chapter 9 Glossary of terms DPOF (Digital Print Order Format) This is for saving desired print settings on digital cameras. By entering which images to print and the number of copies of each, the user can automatically have the desired images printed by a printer or print lab that supports the DPOF format. Effective Pixel Resolution The number of pixels used in the CCD to create the image. EV (Exposure Value) A system for measuring exposure. EV0 is when the aperture is at f1 and the shutter speed is 1 second. The EV then increases by 1 each time the aperture increases by one F stop or the shutter speed increases by one increment. EV can also be used to indicate brightness and ISO settings. Exposure The amount of light used to capture an image. The exposure is determined by the time the shutter is open (shutter speed) and the amount of light that passes through the lens (aperture). Gross Pixel Resolution The total number of pixels in a CCD. Not all pixels are used to create the image. ISO A method for indicating film speed by the International Organization for Standardization (ISO). Higher ISO values indicate greater sensitivity to light, so images can be exposed even in low-light conditions. JPEG (Joint Photographic Experts Group) A compression format for color still images. Photographs (images) shot using this camera are recorded onto the xD-Picture Card in JPEG format when the Record mode is set to SHQ, HQ or SQ. By downloading these images to a personal computer, users can edit them using graphics application software or view the images using an Internet web browser. M (Manual) Mode The user sets both the aperture and shutter speed. NTSC/PAL (National Television Systems Committee/Phase Alternating Line) Television formats. NTSC is mainly used in Japan, North America, Taiwan and Korea. PAL is mainly used in Europe and China. 128

Glossary of terms
DPOF (Digital Print Order
Format)
This is for saving desired print
settings on digital cameras. By
entering which images to print and
the number of copies of each, the
user can automatically have the
desired images printed by a printer
or print lab that supports the DPOF
format.
Effective Pixel Resolution
The number of pixels used in the
CCD to create the image.
EV (Exposure Value)
A system for measuring exposure.
EV0 is when the aperture is at f1
and the shutter speed is 1 second.
The EV then increases by 1 each
time the aperture increases by one
F stop or the shutter speed
increases by one increment. EV
can also be used to indicate
brightness and ISO settings.
Exposure
The amount of light used to
capture an image. The exposure is
determined by the time the shutter
is open (shutter speed) and the
amount of light that passes
through the lens (aperture).
Gross Pixel Resolution
The total number of pixels in a
CCD. Not all pixels are used to
create the image.
ISO
A method for indicating film speed
by the International Organization
for Standardization (ISO). Higher
ISO values indicate greater
sensitivity to light, so images can
be exposed even in low-light
conditions.
JPEG (Joint Photographic
Experts Group)
A compression format for color still
images. Photographs (images)
shot using this camera are
recorded onto the xD-Picture Card
in JPEG format when the Record
mode is set to SHQ, HQ or SQ. By
downloading these images to a
personal computer, users can edit
them using graphics application
software or view the images using
an Internet web browser.
M (Manual) Mode
The user sets both the aperture
and shutter speed.
NTSC/PAL
(National Television
Systems Committee/Phase
Alternating Line)
Television formats. NTSC is mainly
used in Japan, North America,
Taiwan and Korea. PAL is mainly
used in Europe and China.
