Glossary
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.

MJPEG (Motion JPEG)
A video format which is compressed as a JPEG image.
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.

Quality
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.

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