AWB
Auto White Balance-the camcorder attempts to determine the color
temperature of the light and automatically adjust for that color
temperature variability.

temperature variability.
Compression
The process of encoding information using fewer bits cf. video, image or
sound file compression.
sound file compression.
Exif/JPEG
A compressed file format for digital cameras in which the images are
compressed using the baseline JPEG standard, described in ISO 12234-2,
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.
application segment at the beginning of the JPEG file.
Exposure Index
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.
FHD
Full High Definition. This implies 1080p video resolution.
fps Frames
per
second
HD
High Definition. This implies 720p video resolution.
HDMI
High Definition Multimedia Interface – Common connection to HD TVs
ISO Speed
A numerical value calculated from the exposure provided at the focal plane
of an electronic camera to produce specified camera output signal
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.

White Balance
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.
