8.4 Frame rate
The frame rate of camera calculates with below formula with ROI and exposure time settings.
● Formula of frame rate
Frame rate [fps] = 1,000,000 / (Number of lines for one frame x 1 H time [usec.])
1 H time [usec.] = “Hnum” value / 96

* Number of lines for one frame is one of great value of below two values:
(a) Number of lines for one frame = Number of lines of sensor frame + 35
(b) Number of lines for one frame = Number of lines for exposing + 25
* Number of lines of sensor frame
When full resolution, Number of lines of sensor frame = Height setting of camera
When using decimation: Number of lines of sensor frame = Height setting of camera
When using binning: Number of lines of sensor frame = (Height setting of camera) x 2
* Number of lines for exposing = ((Exposure time [usec.] – 7.729) / 1 H time [usec.])
* Integer value (round down)
