The calculation of the camera's acquisition time
The camera's acquisition time is related to the OffsetY and the height of the ROI. When the OffsetY and
height of the ROI is changed, it will affect the front-end acquisition frame period of the camera, then affect
the acquisition frame rate.
The specific calculation formulas are as follows:
1)
MARS-561-207GTM/C
When the pixel format is Mono8 or BayerGB8, row period (unit: μs):
T
row
=
1×176

=2.2
T
fot
=22.0
When the pixel format is Mono10 or BayerGB10, row period (unit: μs):
T
row
=
1×352
80
=4.4
T
fot
=44.0
Camera acquisition time (unit: μs):
T

2)
MARS-900-120GTM/C
When the pixel format is Mono8 or BayerGB8, row period (unit: μs):
T
row
=
2×152

=36.1
When the pixel format is Mono12 or BayerGB12, row period (unit: μs):
T
row
=
2×304
