@ Focusing
If
you
look
at
an
object
through
a
magnifying
glass
and
move
it
closer
or
further
away
from your
eye,
you
will
reach
a
point
where
the
object
becomes
clearly
visible,
and
when
you
move
it
past
that
point,
it
will
become
blurred
again.
Being
focused
or
in
focus
means
that
the
subjéct
is
seen
with
optimum
clarity
and
sharpness.
The
distance
between
the
lens
and
the
point
where
the
rays
of
light
come
together
is
called
“focal
distance”
or
“focal
length”
and
it
depends
on
the
size
and
shape
of
the
lens.
ein Human Eyes
Human
eyes
have
lenses
as
well,
and
when
we
look
at
objects
at
different
distances,
the
shape
of
these
lenses
changes
automatically
so
that
we
can
always
see
these
objects
clearly.
®In the Movie Camera
The
image
of
the
subject
enters
the
Movie
Camera
through
the
lens
and
is
converted
into
an
electrical
signal
(video
signal)
for
recording
onto
magnetic
tape.
In
the
Movie
Camera,
the
“Auto
Focus”
system
automatically
adjusts
the
focal
distance
by
moving
the
focusing
lens
forward
or
backward.
