Frame rate calculation
The calculation formula of frame rate and the value of frame rate are as below.
■
Calculation formula
Vn = Number of vertical line
(The center of the set area is the middle of the sensor.)
Exp1 = 3 ms to 10 s
1H
= 32.4812 × 10
-6
Free running mode
1/(Vn/2×1H)
External trigger mode (Edge/Level)
1/(Vn/2×1H+Exp1+1H×10)
External trigger mode (Synchronous readout)
1/(Vn/2×1H+1H×18)
•
The Exp1 value has to be input to the calculation formula below in units of seconds.
