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 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.
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).
The metering refers to the way in which the camera measures the quantity of light 
to set the exposure.
A video format which is compressed as a JPEG image.
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.
