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.

Discharge: The capacity of rechargeable Ni-MH batteries will drop if they are repeatedly charged without ﬁ rst be-

ing fully discharged. Full capacity can be restored by repeatedly discharging the batteries using the o DIS-

CHARGE option in the camera setup menu and recharging them using a battery charger (sold separately).

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

ing printing.

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 images and sound in a single ﬁ le, with the images

recorded in JPEG format. Motion JPEG ﬁ les can be played in 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.
