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.
