Product data sheet
Horizontal input acquisition
window definition offset in
X (horizontal) direction
A minimum of ‘2’ should be kept,
due to a line counting mismatch
Odd offsets are changing the
C
stream to C
Maximum possible pixel
offset = 4095
Horizontal input acquisition
window definition input
window length in
X (horizontal) direction
No output
Odd lengths are allowed, but will
be rounded up to even lengths
Maximum possible number of
input pixels = 4095
Vertical input acquisition
window definition offset in
Y (vertical) direction
Line offset = 0
Line offset = 1
Maximum line offset = 4095
Vertical input acquisition
window definition input
window length in Y (vertical)
direction
No input lines
1 input line
Maximum possible number of
input lines = 4095
