2) Pulse width mode
・
The exposure time is determined by the pulse width (exposure time = pulse width + 2CLK).
・
The pulse width should be more than 50

11.3 WOI (Window Of Interest)
Only arbitrary areas can be read by specifying an address in horizontal and vertical directions.
Area setting has the following conditions.
・
Number of windows:
1 to 28
・
Setting position:
H: Integral multiple of 4 columns
V: Integral multiple of one row
・
Window size:
H: Integral multiple of 4 columns (minimum size: 16)
V: Integral multiple of one row (minimum size: 2)
・
Overlapping of windows:
Possible
・
Others
(1)Frame rate
There is no proportional relation between the window area and the frame rate.
(2)Set values of the coordinate and the size
Set the coordinate and the size to fit the effective pixel area. Values cannot set
beyond the effective pixel area.
(3)Complex operation
Complex operation with binning and sub sampling is not available.
(4)Memory
WOI setting can be saved in memory banks 1- 8.
