(6-6) Description of menu display by OSD (On Screen Display)
This camera is equipped with the OSD function of superimposing a
character information 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-driven form.
(Note) This camera is basically designed so that all settings can be
done without this menu display by OSD just like the existing
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 operation of menu display]
It can be switched by entering the argument [H'0 to H'4] to the communication command "H'20".
0
: OFF
1 to 4: Menu 1 to 4
(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 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 user unit results in the difference in the brightness of image(shutter speed) between those
when the asynchronous shutter operation in the pulse width control mode is set.
[Description of display content]
MENU 1, 2,3 or 4: Current setting is displayed.
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 decimal system. (Range: 0 to 255).
OFFSET:
The set value of the digital signal OFFSET is displayed in decimal system. (Range: 0 to 255)
