Display layout of OSD
(6-7) 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) Basically, this camera is designed to perform all the settings without menu
display like a conventional FC series camera. However the menu display allows the
user to quickly gain an understanding of 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 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
OSD menu is set to be on as a factory default.
ON/OFF operation of the menu display is done using the serial communication command.
[ON/OFF switching procedure]
Set CR_L(0) (bit 0 of configuration flag) to 1 (OFF) or 0 (ON) following the procedure below.
①
Read out the current CR_L data.
Transmit the command
“RMCL” and acquire the return data.
→
Refer to (6-5).
[Example]
Right figure shows the example of transmitting the command
using the direct command input of TAKENAKA
’s communication
software for evaluation (FCTool)
It turns out that CR_L=0008
Based on this return data, CR_L(0)=0 and OSD menu display is set to ON now.
②
Change the least significant bit of CR_L data to 0(OFF) or 1(ON) and
rewrite the camera setting.
After having changed CR(0) which was read in procedure
①
to 1 or 0,
transmit it to the camera by
“WMCL” command.
[Example]
In the
“CR_L=H’0008”case above, menu setting is changed from ON to OFF by rewriting the camera setting with
CR_L(0)=1. Write the new data
“CR_L=H’0009” setting CR_L(0) to 1.
“WMCL” command is transmitted by the direct command input of FCTool In the right figure.
(Note) The above procedures
①
to
③
can be performed by clicking
”MENU OFF” or ”MENU ON” button on the main
window , when using FCTool.
③
Save CR data to enable the settings at next start-up.
As the CR data set on
②
are stored only on RAM, it will be lost at
the time of power-off. It is needed to send the
“SMCL” command
and to save the set values into the internal nonvolatile
ROM(EEPROM) to enable CR data even after next start-up.
[Example]
Right figure shows the example of transmitting the command
“SMCL” using the direct command of FCTool.
● Switching of the menu page
Set contents are displayed item by item on the plural menu pages.
“WMP” command is used to change the menu page.
[Example]
Right figure shows the example of transmitting the command
“WMP3”
using the direct command input of TAKENAKA
’s communication software for evaluation (FCTool) to switch the menu
page to
“MENU3”.
