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
Horizontal output acquisition
window definition number of
desired output pixels in
X (horizontal) direction
No output
Odd lengths are allowed, but will be
filled up to even lengths
Maximum possible number of input
pixels = 4095
For trigger condition: STRC[1:0] 90h[1:0] = 00; YO + YS > (number of input lines per field
conditions: YO > (number of input lines per field
For trigger condition: STRC[1:0] 90h[1:0] = 00; YO + YS > (number of input lines per field
conditions: YS > (number of input lines per field
Reference for counting are luminance samples.
If the desired output length is greater than the number of scaled output pixels, the last scaled pixel is repeated.
