stage
the moving platform used to mount the slide or film strip holder in
the scanner.
subsampling
the process of reducing the number of discrete pixels in an image by
throwing certain ones away or averaging several together to form a
single one.
tone wedge jump
posterization caused by having too few bits to represent the number
of tones needed in an image.
vector conversion
the conversion of information from scalar to vector. Vector informa-
tion is defined as having magnitude and direction. In other words, a
point in space can be defined in a cartesian coordinate system, and
there is a vector pointing towards that location in space. In imaging,
we can convert a pixel from a value at a particular x, y location, to a
vector number which defines its magnitude as well as its spatial loca-
tion in one number. This system is used extensively to mathematical-
ly represent randomly shaped objects so that computers can “draw”
them.
