Metering
The metering refers to the way in which the camera measures the quantity
of light to set the exposure.
MF (Manual Focus)
A system that manually focuses the camera lens on the subject.
You can use the focus ring to focus on a subject.
MJPEG (Motion JPEG)
A video format which is compressed as a JPEG image.
MPO (Multi Picture Object)
An image le format that contains multiple images in a le. An MPO le
provides a 3D eect on MPO-compatible displays, such as 3D TVs or 3D
monitors.
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).
IP (Internet protocol) address
An IP address is a unique number that is assigned to every device that is
connected to the internet.
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.
