This filter is an anti-alias filter because by attenuating the higher frequencies (greater than the Nyquist frequency), it prevents the aliasing components from being sampled. Because at this stage (before the sampler and the ADC) you are still in the analog world, the anti-aliasing filter is an analog filter.

Digital Anti-Aliasing Filter ... An alternative method is to use a digital anti-aliasing filter. This avoids the noise and drift problems inherent in analog filter circuits, and is the natural approach when the signal is going to be processed digitally anyway.

The Anti-Aliasing filter (aka Optical Low-Pass Filter) is an optical element found in most modern digital cameras. As most digital cameras only measure one colour at each pixel, small points of light may not hit enough pixels to get all the necessary colour information.
