Actual Exposure Time
The actual exposure time is the exposure time specified in ExposureTime plus the image sensor
offset time below.
Image Sensor Offset Time
AP-1600T-USB 14.26 μs
AP-3200T-USB 13.73 μs
When ExposureMode is set to Timed and ExposureTime is set to 1 μs, the actual exposure time will
be as follows.
l
AP-1600T-USB : 1μ+ 14.26μs = 15.26 μs
l
AP-3200T-USB : 1μ+ 13.73μs = 14.73 μs
When ExposureMode is set to TriggerWidth , the exposure is slightly longer than the width of the
trigger signal.
l
AP-1600T-USB : If the exposure time needs to be 15.26μs, set the width of the Trigger Signal to the
camera to 1μ (= 15.26 - 14.26).
l
AP-3200T-USB : If the exposure time needs to be 14.73μs, set the width of the Trigger Signal to the
camera to 1μ (= 15.26 - 14.26).
