EV (Exposure Value)
All the combir/ations ofthe c arneG's shutter speed and l ens
aperture that result inthe s ame exposure.
EV Compensation
This feature allows you t o quickly adjust the exposure value
measured by the c amera, inlimited increments, to improve the
exposure of y our photos, Set the EV compensation to1,0 EV t o
adjust the v alue one s tep darker and 1 .0 E V t oone s tep b righter.
Exif (Exchangeable Image File F ormat)
Aspecification todefine an image file t ormat tor d igital cameras
created by the , Japan Electronic Industries Development
Association (JEIDA).
Exposure
The a mount ot l ight allowed toreach the camera's sensor,
Exposure iscontrolled by acombir/ation of t he shutter speed, the
aperture value, and I SO sensitivity.
Flash
Aspeed light that helps tocreate adequate exposure in low light
conditions.
Focal length
The d istance from t he m iddle ot t he l ens toits focal point
(in millimeters), Longer focal lengths result innarrower angles ot
view a nd t he s ubject ismagnified. Shorter focal lengths result in
wider angles of v iew.
H.264/MPEG-4
Ahigh-compression video format established by international
standard organizations ISO IEC a nd I TU _This codec is capable
ofproviding good video quality at l ow bit r ates developed by the
Joint Video Team (JVT).
Image sensor
The p hysical part ot a digital eamera that eontains aphotosite for
each pixel inthe i mage, Each photosite records the b rightness of
the l ight that strikes itduring an exposure, Common sensor types
are Q CD ( Charge coupled Device) arid C MOS (Complementary
Metal Oxide Semiconductor).
ISO sensitivity
The s ensitivity of t he camera tolight, based on the e quivalent film
speed used inafilm camera. At h igher ISO ser/sitivity settings,
the c amera uses ahigher shutter speed, which can r educe blur
caused by camera shake and l ow light, However, images with
high sensitivity are m ore susceptible tonoise.
