Unlike optical zoom, digital zoom does not increase the amount of visible detail. Instead,
details visible using optical zoom are simply enlarged, producing a slightly "grainy" image.
(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.
(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.
A standard that allows information stored with pictures to be used for optimal color
reproduction during printing.
(Joint Photographic Experts Group): A compressed file 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 Picture Experts Group): MPEG-4 is a movie file format that uses compression to
create files suitable for web distribution. MPEG-4 files can be played in QuickTime 7.0 or
later.
A phenomenon specific to CCDs which causes white streaks to appear when very bright
light sources, such as the sun or reflected sunlight, appear in the frame.
(Waveform Audio Format): A standard Windows audio file format. WAV files have
the extension "*.WAV" and may be compressed or uncompressed. The camera uses
uncompressed WAV. WAV files can be played using Windows Media Player or QuickTime 3.0
or later.
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."
