The Low-Pass Filter
The image sensor that acts as the camera’s picture element is fitted
with a low-pass filter to prevent moiré. If you suspect that dirt or
dust on the filter is appearing in photographs, you can clean the
filter using the Clean image sensor option in the setup menu.
The filter can be cleaned at any time using the Clean now option,
or cleaning can be performed automatically when the camera is
turned on or off.
