Glossary
Digital zoom: Unlike optical zoom, digital zoom does not increase the amount of visible detail.  Instead, details vis-
ible using optical zoom are simply enlarged, producing a slightly “grainy” image.
DPOF (Digital Print Order Format): A standard that allows pictures to be printed from “print orders” stored 
in internal memory or on a memory card.  The information in the order includes the pictures to be printed 
and the number of copies of each picture.
EV (Exposure Value): The exposure value is determined by the sensitivity of the image sensor and the amount 
of light that enters the camera while the image sensor is exposed.  Each time the amount of light doubles, EV 
increases by one; each time the amount of light is halved, EV decreases by one.  The amount of light entering the 
camera can be controlled by adjusting aperture and shutter speed.
Exif Print: A standard for storing information with pictures for optimal color reproduction during printing.
HDMI (High-Defi nition Multimedia Interface): An interface standard for the transmission of images and sound that 
adds audio input to the DVI interface used to connect computers to displays.
JPEG (Joint Photographic Experts Group): A compressed fi le format for color images.  The higher the compression 
rate, the greater the loss of information and more noticeable drop in quality when the picture is displayed.
Motion JPEG: An AVI (Audio Video Interleave) format that stores sound and JPEG images in a single fi le.  Motion JPEG 
fi les can be played in Windows Media Player (requires DirectX 8.0 or later) or QuickTime 3.0 or later.
Smear: A phenomenon specifi c to CCDs which causes white streaks to appear when very bright light sources, such 
as the sun or refl ected sunlight, appear in the frame.
WAV (Waveform Audio Format): A standard Windows audio fi le format.  WAV fi les have the extension “*.WAV” and 
may be compressed or uncompressed.  The camera uses uncompressed WAV.  WAV fi les can be played using 
Windows Media Player or QuickTime 3.0 or later.
White balance: The human brain automatically adapts to changes in the color of light, with the result that objects 
that appear white under one light source still appear white when the color of the light source changes.  Digital 
cameras can mimic this adjustment by processing images according to the color of the light source.  This process 
is known as “white balance.”
