Auto focus refers to a camcorder lens’ ability to

 

 

 

adjust its configuration in order to focus properly on

 

Auto Focus

 

a subject regardless of whether it is near or far from

 

 

the camcorder. Auto focus lenses generally provide

 

(AF)

 

 

 

vastly superior image quality than do their fixed

 

 

 

 

 

 

focus cousins since they do not have to rely on their

 

 

 

depth of field. Also known as: “AF”, “auto-focus”.

 

 

 

The adjustment of electronic still picture color

 

White

 

channel gains or image processing so that radiation

 

 

with relative spectral power distribution equal to that

 

Balance

 

 

 

of the scene illumination source is rendered as a

 

 

 

 

 

 

visual neutral.

 

 

 

With auto white balance, the camcorder attempts to

 

Auto White

 

determine the color temperature of the light and

 

Balance

 

automatically adjust for that color temperature.

 

(AWB)

 

Many people just leave the camcorder set to auto

 

 

 

white balance all the time.

 

 

 

A standardized ASCII file created in a digital

 

Digital Print

 

camcorder and stored on removable media along

 

Order

 

with the image files that indicate how many copies

 

Format

 

of which images should be printed. It also allows

 

(DPOF)

 

index prints, cropping, and text overlays to be

 

 

 

specified.

 

 

 

A compressed file format for digital camcorder in

 

 

 

which the images are compressed using the

 

Exif/JPEG

 

baseline JPEG standard, described in ISO 12234-2,

 

 

and metadata and thumbnail images are stored

 

 

 

 

 

 

using TIFF tags within an application segment at

 

 

 

the beginning of the JPEG file.

 

JPEG

 

Joint Photographic Experts Group. An image

 

 

compression method defined in ISO/IEC 10918-1.
