What Is High Resolution?

High resolution basically means that an image is reproduced with a high level
of detail. Usually it is referring to an image that is of very high quality, where
there is a lot of detail. When talking about high resolution, most people are
usually referring to digital images such as digital photographs, television
resolution either on a standard CRT screen, or digital TV set and computer
monitor resolution. High resolution is also referenced when talking about
digital cameras, scanners, photocopiers and printers.

Digital Camera Resolution

Digital camera resolution is usually measured by mega pixel.
1 Mega pixel (MP) means that there are one million pixels or one million
tiny dots that can be one of various colors creating an image.
Today, you can buy digital cameras that can record digital images of
either 1 mega pixel 1MP all the way up to 10MP or more.
The more mega pixels in an image, usually means a higher quality
resolution. It is important to note that most cameras have a setting
where you can choose the amount of mega pixels per picture. An image
with a higher number of mega pixels require more storage space, so many
people usually choose a lower mega pixel rate that delivers decent
resolution. In addition, many digital cameras can also take pictures
in a variety of aspect ratios.

Computer Monitor

Older monitor screens that are CRT (Cathode Ray Tube) are analog and
similar in resolution quality to standard TV sets. Their resolutions are
usually based on pixels or dots on a screen. These dots make up rows of
lines and ultimately an image. There are two common types of older analog
monitor standards VGA and SVGA. VGA usually has a pixel rate and
resolution of 640 pixels wide by 480 pixels in height. The SVGA monitor
can produce pixel resolution of 800 pixels wide by 600 pixels in height.
It is important to note that some operating systems allow monitors
connected to the computer to increase the resolution. For instance
computer users running Windows XP can enhance their resolution
up to 1024 by 768.

Digital computer monitors, such as LCD monitors, are a little trickier to
state standards, for since many monitors are in various sizes where
standards are not available or referred to. However for most monitors
that are a standard aspect ratio 4:3 (the shape of a standard TV set), the
resolution is usually 800 by 600, 1024 by 768, 1152 by 864
and 1600 by 1200. Remember that width comes first and then height.
These numbers represent the total number of pixels and can vary due to
your personal display settings on your computer's operating system.
