Alias-Effekt
Fig 2
A physical motion of a camera at a constant shutter speed may create temporal aliasing known as the wagon wheel effect. The velocity of the camera, moving towards the right, constantly increases at the same rate . Halfway through the 24-second loop, the objects appear to suddenly shift and head in the reverse direction, towards the right.

When the resolution is reduced without proper filtering, aliasing appears in the form of a moiré pattern.
This full-sized image shows what a properly sampled image of a brick wall should look like with a screen of sufficient resolution.
