(6-7) Description of scan mode and functional limitation
●
Description of scan mode
This camera has the following 2 scan modes which are selectable by setting:
Scan mode
Operation
Frame rate: DUAL
Normal scan mode (NORMAL) Readout of all 5 megapixels
9 fps
Partial scan mode (PARTIAL)
Read out of approx. 1.93 megapixels (790 lines) at the
central area
18 fps
●
Normal scan mode ······· The image of all effective pixels is read out at a frame rate of 9 Hz.
●
Partial scan mode ········· The image of the central area of 790 lines in vertical width is read out at a frame rate of 18 Hz.
This mode is suitable for capturing the image only of the central area at a high speed.
●
Functional limitation by scan mode
Usable functions vary by the scan mode that is currently selected.
The functions marked with
○
in the following table are usable and those marked with
×
are not usable.

(Note) Carefully note that the operation is not guaranteed if an unusable function is selected.
(Note) Caution is required especially when control is executed using the write commands for the flag register among the
serial communication commands because the incompatibility between the selected scan mode and the selected
function is not warned. Setting of an inappropriate parameter results in operation failure.
(6-8) Typical setting procedure
(Example 1) This is the procedure for setting the gain for the
asynchronous shutter operation (1/1000 sec.).
[Explanation]
The left example of the setting procedure is for using the
camera in the asynchronous shutter operation. In the left
example, the operation mode is temporarily set to be the
continuous shutter operation because this makes it easier to
set the gain and others. In the case where the image output
state can be easily checked by way of repeatedly inputting
external trigger signal (Vinit) from a user device, the
operation mode should be set to be “Asynchronous Shutter”
from the beginning before setting the gain and others.
(Note) When the pulse width control mode is set for the
asynchronous shutter operation, the above described
method in which the continuous shutter mode is
temporarily set cannot be used (because the shutter
speed at the position “9” for the asynchronous shutter
mode is different from that for the continuous shutter
mode). If the camera is used in the pulse width
control mode, it is necessary to set the asynchronous
shutter operation and then set the gain and others
while actually inputting the trigger signal (Vinit) from a
user device.
(!)
This equipment is designed so that the pulse width
control mode can be set to OFF even when it is in the
asynchronous shutter mode and the mode switch is at
the position “9”. (Default condition)
(Note) This equipment is automatically put into the condition where the cyclic asynchronous shutter trigger is internally
generated (in the cyclic trigger state) when the menu is displayed.
When the menu is displayed in accordance with the procedure for setting the gain for the asynchronous shutter
operation as described in Fig. 6-3, it is not necessary to temporarily switch to the continuous shutter operation as
shown above.
