Glossary
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.
MPO (Multi Picture Object)
An image file format that contains multiple images in a file. An
MPO file provides a 3D effect on MPO-compatible displays, such
as 3D TVs or 3D monitors.
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.
OIS (Optical Image Stabilization)
This feature compensates in real-time for shaking and vibrating
while shooting. There is no image degradation compared to
Digital Image Stabilization feature.
Optical zoom
This is a general zoom which can enlarge images with a lens and
does not deteriorate quality of images.
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 can reduce blur
caused by camera shake and low light. However, images with
high sensitivity are more susceptible to noise.
JPEG (Joint Photographic Experts Group)
A lossy method of compression for digital images. JPEG images
are compressed to reduce their overall file size with minimal
deterioration of the image resolution.
LCD (Liquid Crystal Display)
A visual display commonly used in consumer electronics. This
display needs a separate backlight, such as CCFL or LED, to
reproduce colors.
Macro
This feature allows you to capture close-up photos of very small
objects. When using the macro feature, the camera can maintain
a sharp focus on small objects at a near life-size ratio (1:1).
