Moir\ufffd is always a problem if the sensor pattern is regular (e.g., rows and
columns) and if there are equally regular features in the image that
approach or exceed the resolution of the sensor.  The only solutions are to
put more pixels in the sensor, randomize the sensor pattern (which is why
film never shows moir\ufffd), or blur the image so that no part of the image
exceeds the resolution of the sensor.
