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 CCD (Charge-coupled Device) and CMOS
(Complementary Metal Oxide Semiconductor).
ISO sensitivity
The sensitivity of the camera to light, based on the equivalent lm speed used in
a lm 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 le 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).
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.
NFC (Near Field Communication)
NFC is a set of standards for radio communication at very close proximity.
You can use NFC-enabled devices to activate features or exchange data with other
devices.
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.
