9.3 White reference mark
9.3.1 Position and size in CCD direction
NOTE
Attention:
The white reference area must not cover the tap border.
For the position in CCD direction of the white reference control zone you have two
alternatives:
“Relative” x position
The x position of the white reference mark can be defined “relative” to the current image
window (ROI).
If defined
relative
, the reference position
moves
if the scan line length of the current scan
Window is changed.
“Absolute” x position
The x position of the white reference mark can be defined “absolute” within the maximum scan
window (for example 4K with a 4K allPIXApro). If defined
absolute
, the reference position
does not
move if the width of the current scan window is changed.
A1= First relative pixel of white reference (may be negative); see section 9.3.3
A2= First absolute pixel of white reference (see section 0)
B = Number of pixel for white reference (see section 9.3.6)
C = First image line of white reference (may be negative),
only used if
white control mode is set
to “sync mode” (see section 0
D = Number of image lines for white reference (see section 9.3.8)
The
Use absolute horizontal position of white reference
check box determines whether
relative or absolute white reference mode is used.
NOTE
If you use
Horizontal Binning
(see section 9.8.4 ), A1 and B refer to the
unreduced image.
If you use
Vertical scan line reduction
(see section 9.8.5 ), C refers to the
unreduced image, while D specifies the length of the white reference mark
within the reduced image.
