Manual gain
Manually configure gain values to adjust the image
brightness.
Auto gain
Automatically adjust the image brightness.
You can also use the EV compensation function to set
compensation between –2.0 EV and +2.0 EV in 0.25 EV
steps.
Iris Control Function
This function allows you to adjust the exposure using the
lens iris. Use a DC iris lens and adjust the iris.
Notes
• Video iris type lenses are not compatible.
• You cannot manually operate the iris.
Auto iris function
Automatically adjust the iris to adjust the image
brightness.
You can also use the EV compensation function to set
compensation between –2.0 EV and +2.0 EV in 0.25 EV
steps.
Lens adjustment function
This camera is equipped with a function that allows
precise adjustment of auto iris lens movement for DC
iris lenses. You can make precise adjustments to image
brightness and lens movement speed with this function.
Detection Area Settings
This camera obtains the data necessary for automatic
exposure adjustment from the image itself. You can
select the location of the detection area from which
luminance data is obtained (luminance detection area).
Note
You cannot use both the auto gain function and the auto
iris function at the same time. When both functions are
enabled, the auto gain function is given priority.
Lookup Table
The lookup table of this camera consists of 1,024 entries
of 10-bit inputs and 10-bit outputs.
The lookup table allows you to configure a gamma curve
or binarization.
The parameters that can be configured are as follows.
0: Equivalent of
γ
=1
1: Equivalent of
γ
=0.45
2: Equivalent of
γ
=2.2
3: Reverse
4: Binarization (1 to 1,023 threshold)
Filter Function
This camera allows simple image processing on the
hardware using the 5 × 5 image filter.
On color models, individual configuration of RGB filter
coefficients is possible.
Images before and after filter processing can also be
transferred to memory simultaneously.
VIDEO Format
In order to support various types of image processing
libraries, this camera is equipped with multiple formats
for image transfer.
Ten output modes are available for color models, and
two output modes are available for black and white
models.
The output modes that can be selected are as follows.
• Y8:
An output mode that uses Y8 bit to represent 1 pixel.
• RAW8 (color models only):
An output mode without color processing that uses 8
bits to represent 1 pixel.
