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.

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 that allows information stored with pictures to be used for optimal color reproduction dur-

ing printing.

JPEG (Joint Photographic Experts Group): A compressed  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 images and sound in a single  le, with the images

recorded in JPEG format. Motion JPEG  les can be played in QuickTime 3.0 or later.

Smear: A phenomenon speci c to CCDs which causes white streaks to appear when very bright light sources, such

as the sun or re ected sunlight, appear in the frame.

WAV (Waveform Audio Format): A standard Windows audio  le format. WAV  les have the extension “*.WAV” and

may be compressed or uncompressed. The camera uses uncompressed WAV. WAV  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.”
