1.1.1. Have a Look!

remark

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.
