Notes on the Camera
Operations
If Frame Rate Decrease Occurs
On this camera, frame rate may decrease depending on
your shutter settings.
a
When the exposure time is shorter than one frame,
and the exposure time setting is shortened using the
shutter
In this case, the camera tends to skip 1 frame image,
resulting in a decrease in the frame rate. Keep this in
mind when using an application that switches exposure
times frequently.
b
With a long exposure
In long exposure mode, the exposure time is set
longer than the image transmission cycle. In this
case, frame rate decreases according to the exposure
time.
When Using Trigger Mode
This camera is set to accept a trigger at the fastest
possible timing and it can accept overlap of the next
trigger signal during video transmission as the default
setting. For this reason, a trigger inhibition period is not
available. Thus, if a trigger signal is input before the
CCD can change to the state where it can accept
exposures, multiple exposures can occur, and it cannot
capture the correct image. Design the trigger generation
circuit so that the trigger cycle is not faster than
necessary.
For the same reason, a malfunction may occur when
noise overlaps a trigger signal. In this case, suppress
noise in the trigger generation circuit.
Accuracy of Auto White Balance
This camera integrates the R, G and B levels within the
area specified by the AWB detection area, and adjusts
the R and B gains so as to equalize each level. For this
reason, the correct white balance is obtained when a
white subject is shot on the whole detection area.
The correct color reproduction may not be obtained
during a normal scene shooting.
Note on CompactFlash
This camera does not perform proper shutdown
procedures through software when the system restarts in
response to the watchdog timer, or when the external
power source is cut off. As a result, the file system of the
CompactFlash may be damaged depending on your
operating system or applications. Be sure to take proper
precautions such as configuring a protection (EWF,
CHKDSK, etc.) for the CompactFlash.
Error Message during BIOS Startup
When starting up the BIOS for the first time after
purchase or after prolonged periods of disuse, a
“SystemError” message may appear. Although this
camera is equipped with an RTC (real-time clock), it is
not equipped with a backup battery. As a result, the
clock may stop and the above error message may appear
after prolonged periods of disuse. This message
indicates that the clock time is incorrect. To correct the
clock, connect a mouse and keyboard, select Run Setup,
and then adjust the calendar and clock settings in the
BIOS setup screen. To proceed without adjusting the
clock, select Continue. The BIOS will then start up
properly.
