Definition
Auto White Balance-the camcorder attempts to determine the color
temperature of the light and automatically adjust for that color
temperature variability.
The process of encoding information using fewer bits cf. video, image or
sound file compression.
A compressed file format for digital cameras in which the images are
compressed using the 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.
A numerical value that is inversely proportional to the exposure provided to
an image sensor to obtain an image. Images obtained from a camera using a
range of exposure index values will normally provide a range of image
quality levels.
Full High Definition. This implies 1080p video resolution.
Frames per second
High Definition. This implies 720p video resolution.
High Definition Multimedia Interface – Common connection to HD TVs
A numerical value calculated from the exposure provided at the focal plane
of an electronic camera to produce specified camera output signal
characteristics using the methods described in the referenced standard. The
ISO speed should correlate with the highest exposure index value that
provides peak image quality for normal scenes.
Joint Photographic Experts Group. An image compression method defined in
ISO/IEC 10918-1.
Light Emitting Diode
On Screen Display – Usually a reference to the user interface of the
camcorder or camera.
Universal Serial Bus. A digital interface for connecting up to 64 devices in a
tiered-star topology. See http://www.usb.org.
Video Graphics Array. This is associated with 640 x 480 resolution and is
often call "standard definition"
The adjustment of electronic still picture color channel gains or image
processing so that radiation with relative spectral power distribution equal
to that of the scene illumination source is rendered as a visual neutral.
