Camera operation modes
W-VIEW Mode can work with Free running mode, Edge trigger mode, Level trigger mode,
Synchronous readout trigger mode and Start trigger mode. The exposure time can be set
independently for the top and bottom areas with Free running mode, Edge trigger mode and Start
trigger mode.
Note
•
Please refer to 9-3-5 [Timing chart of camera operation modes] about the detail of timing
chart of these modes.

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 (Size of the area of one side)
Exp1 = 3 ms to 6 s
1H
= 32.4812 × 10
-6
Free running mode
1/(Vn×1H)
External trigger mode (Edge/Level)
1/(Vn×1H+Exp1+1H×10)
External trigger mode (Synchronous readout)
1/(Vn×1H+1H×18)
•
The Exp1 value has to be input to the calculation formula below in units of seconds.
