text: This type of distortion is known as moiré, and most digital cameras try to limit this via an anti-aliasing filter which smooths over the higher spatial frequencies (softening un-resolvable detail) and allowing only the lower frequencies (hence the alternate term ‘low pass filter’) to pass through the sensor.
