Frame Rate Control

The camera provides the following two methods for
frame rate control during internal continuous drive
operation.
Auto Frame Rate setting
The fastest frame rate is configured automatically based
on the current Exposure Time and Partial Scan settings.
This is the default frame rate control setting for the
camera.
To increase the frame rate, activate Partial Scan mode.
Depending on whether the exposure time is longer than
the frame period, the frame rate will be reduced
proportionally. Therefore shorten the exposure time as
necessary.
Setting parameter: AcquisitionFrameRateAuto = On
Frame Rate setting
The frame rate can be set manually. However, you
cannot increase the frame rate beyond the fastest setting.
In addition, if the exposure time is longer than the
configured frame period, the frame rate will be reduced
in proportion to the exposure time.
When you want to reduce network traffic, use this
setting to lower the frame rate while maintaining the
same Exposure Time setting.
Setting parameters: AcquisitionFrameRateAuto = Off
AcquisitionFrameRate = 0.0625
Frame rate indication
The camera has a frame rate display function for
verifying the frame rate obtained using the above
settings. By using this function, you can confirm that an
anticipated frame rate has been obtained.
Observation parameter: AcquisitionFrameRateActual

Look-Up Table (LUT)

The look-up table of the camera consists of 4,096 values,
with 12-bit input and 12-bit output. The look-up table
allows setting an arbitrary gamma curve or binarization.
Selectable from 0: Linear 1: Reverse 2: Binarization 3:
5-Point Linear Interpolated LUT 4: User Setting.
5-Point Linear Interpolated LUT
By specifying the input (X) and output (Y) each for 5
points as desired, you can create an LUT through linear
interpolation between the specified points.
The specified points are sorted by inputs (X), then an
LUT is created by linearly interpolating between (0,0)
and (X1,Y1), ..., then (X5,Y5) and (4095,4095).
Setting parameters:LinearInterpolationIndex = 1
LinearInterpolationInValue = X1
LinearInterpolationOutValue = Y1
LinearInterpolationIndex = 5
LinearInterpolationInValue = X5
LinearInterpolationOutValue = Y5
