Glossary

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. 

This is a general zoom which can enlarge images with a lens and 
does not deteriorate quality of images.

An expression of the rate of compression used in a digital image. 
Higher quality images have a lower rate of compression, which 
usually results in a larger file size.

The number of pixels present in a digital image. High resolution 
images contain more pixels and typically show more detail than 
low resolution images.

Shutter speed refers to the amount of time it takes to open and 
close the shutter, and it is an important factor in the brightness of 
a photo, as it controls the amount of light which passes through 
the aperture before it reaches the image sensor. A fast shutter 
speed allows less time to let light in and the photo becomes 
darker and more easily freezes subjects in motion.

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. 

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.
