5.4.1.1 Input
sub-section
Input: Crop – Horizontal and Vertical
The crop controls allow selection of a portion of the original image – the amount of horizontal and vertical cropping is
expressed as a percentage of the size of the original image.
The user can manually adjust the level of horizontal and vertical cropping. Horizontal cropping is done on an 8-pixel
basis. Vertical cropping is done on 4-line basis. To achieve non-symmetrical vertical or horizontal cropping, uncheck
the
Center
box underneath and position the image using the
Tilt
function described below.
Input cropping changes the scaling factor between the input and the output. If we crop the input (H&V) by 10%, the
output image is resized and scaled by +10%. By providing different H and V cropping, the user can produce an
anamorphic image.
The padlock icon appearing next to the data window allows the data to be “locked”. See the paragraph
Locking
controls
under
Output sub-section
below for a discussion of this option.
Input: Tilt
Once a smaller window has been established by cropping the input signal, it can be moved vertically (
Tilt
, expressed
in lines) within the original image to place the desired portion of the image in view. By default, a
Center
check box
beneath the Tilt scroll box forces the cropping window to be centered on the input window. When it is checked, the
necessary Tilt value will be calculated and displayed in the Tilt data window. You cannot tilt if the cropping value is
zero.
Input: Pan
Once this smaller window is established, it can be moved horizontally (
Pan
, expressed in pixels) within the original
image to place the desired portion of the image in view. A
Center
check box beneath the Pan scroll box forces the
cropping window to be centered on the input window. When checked, the necessary Pan value will be calculated and
displayed in the data window. You cannot Pan if the cropping value is zero.
5.4.1.2 Output
sub-section
Output: Side Panels
This scrollable data entry box is used to shrink the width of the image so that the output image has blanked areas on
each side of the displayed picture, which occupy the indicated percentage of the screen width. These areas are
symmetric about the center, so a setting of 25% side panels would show a bar 12.5% of the screen width on each
side of the image. 25% is the maximum value; entering a smaller value reduces the width of the side panels, but crops
the image top and bottom. This control is disabled when the input is 16:9.
Output: Anamorphism
This control box allows the output image to be resized asymmetrically. Anamorphism is expressed in percent, where
positive values indicate an increase in width with respect to height, and negative values a decrease in width with
respect to height.
Output: Position
This pulldown allows the positioning of the output picture when side panels are in use. The picture can be moved
totally to the left, centered or totally to the right. This control is not available in Auto AFD mode or Forced AFD mode.
The picture will be centered by default when an ARC Preset is selected.
Locking
controls
Represented by padlock icons, these buttons allow the
V Crop
,
H Crop,
Side Panels
and
Anamorphism
controls to be
“locked”. When a control is locked, user access to that control is disabled. Changes to unlocked controls will not affect
the data values of locked controls. There is some interactivity within the locking function, as follows:
•
If
either
V Crop
or
H Crop
is locked,
Anamorphism
is unlocked.
•
If
either
Side Panels
or
Anamorphism
is locked, the other is unlocked, along with
V Crop
and
H Crop
.
