H.264/MPEG-4
A high compression video format established by international
standard organizations ISO lEO and ITU T and developed by the
Joint Video Team (JVT). This codec is capable of providing good
video quality at low bit rates.
Image sensor
The physical part of a digital camera that contains a photosite for
each pixel in the image, Each photosite records the brightness of
the light that strikes it during an exposure, Common sensor types
are QCD (Charge coupled Device) and CMOS (Complementary
Metal Oxide Semiconductor).
ISO sensitivity
The sensitivity of the camera to light, based on the equivalent film
speed used in a film camera, At higher ISO sensitivity settings,
the camera uses a higher shutter speed, which car/reduce blur
caused by carnera shake and low light, However, images with
high sensitivity are more susceptible to noise.
JPEG (Joint Photographic Experts Group)
A Iossy method of compression for digital images. JPEG images
are compressed to reduce their overall file size with minimal
deterioration of the image resdution.
LCD (Liquid Crystal Display)
A visual display cornmonly used in consurner electronics, This
display needs a separ_te backlight, such as CCFL or LED, to
reproduce colors.
Macro
This feature allows you to capture close tip photos of very small
objects. When using the macro feature, the camera car/maintain
a sharp focus on small objects at a near life size ratio (1:1).
Metering
The metering refers to the way in which the camera measures the
quantity of light to set the exposure.
MJPEG (Motion JPEG)
A video format which is compressed as a JPEG image.
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.
