If the camcorder is moved while the shutter is open, the entire image may appear blurted
This occurs more otten when the shutter speed is slow Prevent camcorder shake by
raising the sensitivity, using a faster shutter speed Alternately, use a tripod, the DIS or OIS
function to stabilize the camcorder

GMOS is an image sensor producing images approaching the quality of GOD (charge
coupled device) sensors It consumes less power, meaning a longer battery life on your
camcorder

A feature that artificially increases the amount of zoom available with zoom lens (Optical
zoom) W/_en using the Digital zoom, the image quality will deteriorate as the magnification
increases

The amount of light allowed to reach the camcorder's sensor Exposure is controlled by a
combination of the shutter speed, the aperture value, and ISO sensitivity

The distance from the middle of the lens to its focal point (in millimeters) Longer focal
lengths result in narrower angles of view and the subject is magnified Shorter focal
lengths result in wider angles of view
The f number defines the brightness of lens Smaller number lens has generally brighter
image The f number is directly proportional to the focal length and inversely proportional
to the lens diameter

MPEQ 4 AVQ/H 264 defines the latest video coding format standardized by the ISO IE©
and the ITU T, in 2003 Compared with the conventional MPEQ 2 toFnat, MPEQ 4 AVQ/
H264 has more than twice the eflicieney Your camcorder employs MPEQ 4 AV©/H 264
to encode high definition videos

This is a general zoom which can enlarge images with a lens and does not deteriorate
quality of images
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 file size

The number of pixels present in a digital image High resolution images contain more
pixels and typically show more detail than low resolution images

Shutter speed refers to the amount of time it takes to open and close the shutter, and it
is an important faetor in the brightness of a photo, as it controls the amount of light which
pass through the aperture before it reaches the image sensor A fast shutter speed allows
less time to let light in and the photo becomes darker and more easily freezes subjects in
motion

This feature allows you to capture close up images of very srnall objects When using the
Tele Macro feature, the camcorder can maintain a sharp focus on small objects at a near
lite size ratio (1:1)

An adjustment of the intensities of colors (typically the primary colors red, green, and
blue), in an image The goal of adjusting the white balance, or color balance, is to correctly
render the colors in an image
