1.1.1. Have a Look!
Have a look at the following animation. By clicking on the red rectangle you get an enlarged view of a picture's detail.
At first you see a wonderful landscape with beautiful colours. You notice
that the image shows a lake with some mountains in the background. But if you
zoom in very close you can't identify an object anymore. You only see thousands
of tiny coloured elements. This is exactly the way objects are displayed on a
screen.
The next chapters will deepen the theory about
some aspects related to screens. Some issues you might have already heard in
other lectures, but since they are very important for the understanding of the
further units, we mention them anyway.
