(6-4) Description of menu display by OSD (On Screen Display)
This camera is equipped with the OSD function of imposing a text on the
output digital image signal. Using this function, the current setting status
of the camera can be displayed over the image of the capture board in
menu form.
(Note) This camera is basically designed so that all settings can be done
without this menu display by OSD just like the conventional
cameras of FC series. However the menu display allows the user
to quickly understand the current settings at a glance.
Furthermore, if the contents of the menu display are captured and
saved before collecting data using the camera, they serve as
useful information to be referred when comparing data or setting
additionally introduced cameras.
[Requirement for menu display]
The menu display requires a system that is capable of updating the captured image constantly responding to the timing of
FDV/LDV to be output from the camera on the side of the user's capture board.
When the asynchronous shutter mode is set for the camera, the repetitive asynchronous shutter operations are
automatically made at certain intervals to automatically refresh the image so that the menu display is updated. During this
process, the externally input trigger signals are ignored.
The display area of OSD is located on the upper left on the entire area of the captured image, and therefore this system
must be additionally capable of displaying this menu on the screen.
[ON/OFF of menu display]
If the OSD menu display does not appear on the capture image, perform the following procedure to display it:
Turn on the power in the normal manner → Set the mode switch to "1" → Apply an upward stroke to the UP/DOWN switch
To disable the output of the menu display, perform the same procedure except for applying a downward stroke to the
switch.
(Note) Since the ON/OFF setting of the menu display is a configuration item, it is automatically saved in the internal
EEPROM.
(Note) If the menu display is set to be ON in the asynchronous shutter mode, the repetitive trigger (cyclic trigger) that is
generated inside the camera is automatically input. Make sure to set the menu display to OFF when the camera is
used in the normal state (online state).
(Note) Note that the difference between the pulse width generated by the camera with the menu display turned on and
that provided by the actual user unit results in the difference in the brightness of image between those, when the
asynchronous shutter operation in the pulse width control mode is set (S.FORM=ASYNC/HIGH,
PWC=ENABLED).
[Description of display content]
MENU 1, 2, 3 or 4: Current setting is displayed.
The following is displayed:
"1": Setting content of Setting Group 1
"2": Setting content of Setting Group 2
"3": Setting content of Setting Group 3
"4": Setting content of Setting Group 4
MENU:
Current menu status is displayed.
When the menu is being displayed, "ON" is kept displayed.
When "(CYCLIC)" is displayed on the right, the camera is cyclically outputting the asynchronous shutter
image using the internal trigger to refresh the image.
When the asynchronous shutter mode is set and the menu is set to ON, the cyclic trigger input is
automatically selected. When the menu is set to OFF, the cyclic trigger input is automatically cancelled and
external trigger is ready to be received.

●
GAIN:
The left number is the gain setting value expressed in the decimal system.
When gain and offset set value coincides with preset value (four
levels of preset value), "SET" followed by corresponding preset No.
is displayed on the right side.
OFFSET:
The setting value of the digital signal offset is displayed in the
decimal system.
S.TIME:
The current shutter exposure time is displayed. The left number is
H number (horizontal synchronous time unit, in the case of high
speed shutter – range: 1 to number of horizontal lines in decimal
system) or V number (vertical synchronous time unit, in the case of
low speed shutter – range: 1 to 50 in decimal system). The right
number in parentheses shows the actual time.
The actual time is displayed after being converted in accordance
with the settings of the scan mode (all pixels/partial) and shutter
mode (HIGH/LOW).
