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

b When the shutter is set to Auto, and the exposure

time decreases automatically

In either 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.

c 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.

When the above conditions are unavoidable, the trigger

inhibition period can be limited only while the image is

being output.

Keep in mind, however, that if the trigger inhibition

feature is enabled, the overlap trigger cannot be accepted

and the minimum trigger input cycle becomes longer

according to the exposure time.

On Sensitivity in Binning Mode

In the Binning mode, the vertical signal is factored in, so

the sensitivity is doubled. The frame rate is also doubled

and the exposure time is halved, so this effect is canceled

out.

On the other hand, when a shorter exposure time is set,

the effect of this inclusion appears, and the sensitivity

increases. When setting the exposure time in the

Binning mode, take this into consideration.

Auto Shutter Control and Absolute

Value Shutter Control

The auto shutter control function cannot be used in the

Absolute value control mode. When Shutter is set to

AUTO, the Absolute value control mode is

automatically canceled.

On Accuracy of Auto White Balance

This camera integrates the R, G and B levels within the

area specified by the AWB detection frame, and adjust

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 frame.

The correct color reproduction may not be obtained

during a normal scene shooting.
