PAL (Phase Alternate Line)
A video color encoding standard used in numerous countries throughout
Africa, Asia, Europe, and the Middle East.
Quality
An expression of the rate of compression used in a digital image. Higher
quality images have a lower rate of compression, which usually results in a
larger le size.
RAW (CCD raw data)
The original, unprocessed data, collected directly from the camera’s image
sensor. White Balance, contrast, saturation, sharpness, and other data can
be manipulated with editing software before the image is compressed into
a standard le format.
Resolution
The number of pixels present in a digital image. High resolution images
contain more pixels and typically show more detail than low resolution
images.
Noise
Misinterpreted pixels in a digital image that may appear as misplaced or
random, bright pixels. Noise usually occurs when photos are shot with a
high sensitivity or when a sensitivity is automatically set in a dark place.
NFC (Near Field Communication)
NFC is a set of standards for radio communication at very close proximity.
You can use NFC-enabled devices to activate features or exchange data
with other devices.
NTSC (National Television System Committee)
A video color encoding standard used most commonly in Japan, North
America, the Philippines, South America, South Korea, and Taiwan.
Optical zoom
This is a general zoom which can enlarge images with a lens and does not
deteriorate quality of images.
