What is the "aperture problem"?..

Answer / kaladhar

The aperture problem arises as a consequence of the
ambiguity of one-dimensional motion of a simple striped
pattern viewed through an aperture. Consider one image that
can be used to construct apparent motion through an
aperture. The striped background is masked by an occluding
porthole. If we move the stripes upwards the pattern of
lines in the aperture shifts. If we move the stripes
leftwards the pattern within the aperture shifts in the
same way.
