Video
digitizers
A
video
digitizer
is
a device that converts images into a digilal form
that the
computer
can
store
and
display. Many digitizers look like
small video cameras, and
in
a
sense
they arc. But instead
of
record·
ing an image
on
tape, they record the image in the computer's
memory,
where
you can modify the image
and
store it
on
disk.
Other
digitizers
can
scan printed
material-magazine
pages,
photographs,
drawings-and
convert them
to
digital form for
editing
and
storing
on
disk.
Additional
memory
Many users find themselves creating larger
documents
than
they
expected
or
buying powerful applications that
demand
more
memory. To ensure that your computer
can
handle these demands,
Apple has
engineered
its
computers
so
you can
add
memory
up
to
one
megabyte (in
2S6K
increments). Some
programs
can
run faster
when
extra
memory
is available.
Graphics
tablets
A
graphics
tablet
is
an
elearonically
sensitive tablet that connects
to the computer.
As
you
dnw
on
the tablet (with a stylus or
other
device), your work
appears
on
lhe screen. Most graphics tablets
contain a palette
of
colors that you can
work
into
your
creation.
Work created with a
gnphics
tablet can be saved
on
disk
and
printed.
Co-processors
A
co-processor
is a microprocessor that works with
or
overrides the
computer'S
own
microprocessor. A
co~processor
can
lake
advantage
of
software
developed
for
other
computers-software
that wouldn't otherwise work
on
an
Apple computer.
