(!) Sometimes light and dark may be reversed because of vertical binning of image signal when the image signal
becomes excessively saturated. In that case, lower the image signal level (e.g. by
lens a notch)
(!) If the double speed scanning is used in the color camera (FS11000GE), it becomes difficult to obtain the normal
color image as the color information is also added up.
[Terminology] Preset shutter ·········· This refers to the shutter speed setting other than those specified by the pulse width
[Terminology] Pulse width control ····· This is the way of setting and controlling of the shutter speed by the width of the Vinit
[Terminology] High speed shutter ····· This means the shutter of which shutter speed is shorter than 1 frame duration (=1
[Terminology] Low speed shutter ······ This means the shutter of which shutter speed is longer than 1 frame duration. The

Image signal is output from light-and-left output ports simultaneously. High speed
readout is realized by using two output ports.( High frame rate)
Image signal is output from single output port. Stable image can be obtained by using
single output port sacrificing the frame rate to some extent.
Electronic shutter is not used.
Exposure time of image sensor is equivalent to one frame duration.
Exposure is continuously performed for each frame.
Repeats exposure regardless of external trigger input (Vinit).
Repetition pitch is per frame.
Electronic shutter is released each time the external trigger is input (Vinit).
The shortest repetition pitch is [exposure time + 1 frame duration].
Shutter ,of which the exposure time is less than one frame, is used.
The exposure time can be set as a preset shutter speed at 9 different levels both for
the continuous shutter/asynchronous shutter operations.
The shutter, of which the exposure time is two frames or over, is used.
(Only for continuous shutter mode) The exposure time can be set as a preset shutter
speed at 9 different levels.
(Note) This camera allows this setting only for the continuous shutter mode.
Only in the case of asynchronous shutter setting, the shutter, of which the exposure
time corresponds to the pulse width (during L level) of the external trigger input
(Vinit), is released.
Exposure time can be set as nH (n = 1 or larger integer number) in H (horizontal
synchronous time) unit.
The readout for each frame is conducted by the all pixel readout scanning.
The readout for each frame is conducted by the double speed scanning (2 lines
binning). Image data is vertically compressed in half.
control. More specifically, the shutter speed is set by the shutter switch positions
from "1" to "9" for the continuous shutter operation, or the shutter switch positions
from "1" to "9" (PWC (Pulse width control mode)=DISABLED) or from "1" to "8"
(PWC (Pulse width control mode)=ENABLE) for the asynchronous shutter operation.
The shutter speed is defined in the Table 6-1.
signal that is externally input in the asynchronous shutter mode. With this camera,
this is selected by setting PWC to "ENABLED" and the shutter switch position to "9"
in the asynchronous shutter mode.
vertical synchronous time). The shutter speed is set as a preset fixed length of the 9
different levels that are determined by the position of the shutter switch (continuous
shutter and asynchronous shutter).
