These artifacts are two of the most common effects of aliasing . Aliasing is defined to occur when a continuous signal (in this case the image projection of the geometric model of a scene) is sampled (converted to discrete pixels) using sample locations (pixels) that are too widely spaced relative to ...

Antialiasing of Interlaced Video Animation

Temporal aliasing will occur if there is overlap (see: Figure 2) with the sideband to the right at (60 Hz, 0 cycles per scanline). This type of problem also appears in motion pictures.
