P. SCAN (P
rogressive Scan
)
Function
Unlike a regular Interlace Scan in which two fields of picture information are alternated to
create the entire picture (odd scan lines, then even scan lines), Progressive Scan uses
one field of information
(
all lines displayed in one pass
)
to create a clear and detailed
picture without visible scan lines.
While the player is in the Stop mode
,
hold the RSCAN button down for _
longer
than 1
second.
• The selection switches back and forth between "t .SCAN" and "7.SCAN" each time the
button is held down for a minimum of 1 second.
• The previous mode is indicated in the display first, followed by the selected mode in about
a second.

Progressive Scan
(FULL FRAME)
In interlaced
-scan video,
a frame
consists of two
Interlaced fields
(odd and even),
where
each field
contains every other horizontal fine In the frame.
The odd field of alternating
lines is displayed
first, and
then the even field is displayed to fill in the allemating
gaps left by the odd field to form
a single frame.
One frame, displayed every 1/30th of a second, contains
two interlaced fields, thus a total of 60 fields are
displayed every 1/60th of a second each.
The interlaced scanning method
is intended
for capturing
a still object.
The progressive scanning method scans one full frame of
video consecutively down the screen
,
line by line.
As opposed to the interlaced scanning process by which a
video image is drawn in a series of passes
,
you get an
entire Image drawn at one time.
The progressive scanning method
is desirable for dealing
with moving objects. A camera that has the ability to
capture moving objects Is called a'full frame shutter
camera'
