Sensor Readout (Sensor Output)
This signal indicates that exposure has completed and the CCD has entered the video output sequence, Output is
available from the GPO1, 2 or 3 terminals. The sensor readout signal is asserted before optical black and the effective
pixel area is output. If the following trigger signal is input when this signal is asserted, horizontal line noise may occur
in an image. The trigger shift function (page 22) can effectively prevent noise contamination.
The time required for the CCD to start OB (optical black) and effective pixel output after sensor readout signal assertion
is shown below. OB is not output from a camera.
* When VBIN=2, increase of approximately 3 µs.
**When OFFSETX= 0, OFFSETY= 0, shortest value.
