Image presampling filters
In a video camera, continuous information must be
subjected to a presampling ("antialiasing") filter.
Aliasing is minimized by optical spatial Iowpass filtering
that is effected in the optical path, prior to conversion
of the image signal to electronic form. AATF limitations
in the lens impose some degree of filtering. An addi- ...
