Digitalzoom:Unlike optical zoom, digital zoom does not increasetile amount of visible detail. Instead,details vis-
ible using optical zoom aresimply enlarged, producing aslightly "grainy" image.
DPOF(Digital Print Order Format):A standard that allows pictures to be printed from "print orders" stored mml_°
in internal memory or on a memory card. Tile information in the order includes the pictures to be
printed and the number of copies of eachpicture. DPOF
EV(Exposure Value):The exposure value isdetermined by the sensitivity of the image sensor and the amount
of light that enters tile camera while the image sensor is exposed. Eachtime tile amount of light doubles, EV
increasesby one;each time the amount of light is halved,EVdecreasesby one. The amount of light entering the
camera carl be controlled by adjusting aperture and shutter speed.
ExifPrint:Astandard that allowsinformation stored with pictures to be usedfor optimal color reproduction dur-
ing printing.
JPEG(Joint Photographic Experts Group):Acompressed file format for color images. The higher tile compression
rate,the greater tile lossof information and more noticeable drop in quality when the picture isdisplayed.
MotionJPEG:An AVI(Audio Video Interleave)format that stores images and sound in a single file,with the images
recorded in JPEGformat. Motion JPEGfiles carl be played in QuickTime 3.0or later.
Smear:A phenomenon specificto CCDswhich causeswhite streaksto appear when very bright light sources,such
asthe sunor reflected sunlight, appear in the frame.
Whitebalance:Tile human brain automatically adapts to changes in the color of light, with tile result that objects
that appear white under one light source still appear white when the color of the light source changes. Digital
camerascarl mimic this adjustment by processing imagesaccording to the color of tile light source. This process
is known as"white balance."
