Glossary
DIS (Digital Image Stabilization)
This feature compensates in real-time for shaking and vibrating while shooting.
There can be a certain amount of image degradation compare to Optical Image
Stabilization.
EV (Exposure Value)
All the combinations of the camera's shutter speed and lens aperture that result in
the same exposure.
EV Compensation
This feature allows you to quickly adjust the exposure value measured by the
camera, in limited increments, to improve the exposure of your photos. Set the EV
compensation to -1.0 EV to adjust the value one step darker and 1.0 EV to one step
brighter.
Exif (Exchangeable Image File Format)
A specification to define an image file format for digital cameras created by the
Japan Electronic Industries Development Association (JEIDA).
Exposure
The amount of light allowed to reach the camera's sensor. Exposure is controlled by
a combination of the shutter speed, the aperture value, and ISO sensitivity.
Flash
A speed light that helps to create adequate exposure in low-light conditions.
Focal length
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.
Histogram
A graphical representation of the brightness of an image. The horizontal axis
represents the brightness and the vertical axis represents the number of pixels. High
points at the left (too dark) and right (too bright) on the histogram indicate a photo
that is improperly exposed.
H.264/MPEG-4
A high-compression video format established by international standard
organizations ISO-IEC and ITU-T and developed by the Joint Video Team (JVT). This
codec is capable of providing good video quality at low bit rates.
