4. Camera Functions
4.1.1 ROI (Region Of Interest)
By setting Width, Height, Offset X, and Offset Y, you can output only the image of the desired area. Output Height
As the size gets smaller, the frame rate increases.
| Feature | Value | Description |
|---|
| WidthMax / HeightMax | (Read Only) | Maximum output size of the image. |
| Width / Height / Offset X / Offset Y | (Integer) | Changes the image output size and offset in pixel coordinates.
WidthMax ≥ Offset X + Width
HeightMax ≥ Offset Y + Height |
＊Frame rate changes due to ROI can be checked through the ‘Resulting Frame Rate’ Feature.

4.1.2 Binning
This is a function that cumulatively reads adjacent pixels in the horizontal or vertical direction. Same as Decimation
While it has higher resolution, binning can also increase sensitivity by about two times because video signals are added.
Because digital binning is applied, the frame rate does not increase, but when ROI is applied together, the frame rate increases.
You can do it.

2,147,483,647
(Unit : 12bit DN) | Sets the Histogram Max value. Brightness corresponding to the setting is stretched to 4095. |
＊Ex) When Min = 320, Max = 2000 are set, 20DN and 125DN based on 8 bits are stretched to 0DN and 255DN, respectively.
4.10.4 Auto Contrast
Auto Contrast is a function that automatically corrects the image by setting the factor and target. The factor setting value is set to the target.
Correct the image by stretching it to the set value. Factor Low and Factor High are the lowest and lowest pixels in the entire image, respectively.
This is the upper percentage value, and Target Low and Target High are 12bit DN values (0~4095).
| Feature | Value | Description |
|---|
| Auto Contrast Mode | Off | - Off : Manually set Contrast and Brightness
- Once : Turns Auto Contrast off when each factor reaches the target brightness
- Continuous : Continuously adjusts Contrast and Brightness |
| Once | |
| Continuous | |
Auto Contrast Factor
Low | 0 ~ 50
(Unit : %) | Sets Auto Contrast Factor Low. This is the lower percentile of all image pixels. |
Auto Contrast Factor
High | 0 ~ 50
(Unit : %) | Sets Auto Contrast Factor High. This is the upper percentile of all image pixels. |
Auto Contrast Target
Low | 0 ~ Auto
Contrast Target
High-1
(Unit : 12bit DN) | Sets Auto Contrast Target Low. Brightness (DN) corresponding to Auto Contrast Factor Low is stretched to the target brightness (DN). |
| Feature | Value | Description |
|---|
| Auto Contrast Target High | Auto Contrast Target Low+1 ~ 4095
(Unit : 12bit DN) | Sets the Auto Contrast Target High value. Brightness (DN) corresponding to Auto Contrast Factor High is stretched to the target brightness (DN). |
| Contrast Update Feature | Command | Updates Contrast, Brightness, Histogram Stretch Min, and Histogram Stretch Max. |
＊If the original video is too dark, noise may increase.
4.11 Sensor Cooling Control
This function controls the sensor temperature. The sensor temperature that guarantees the best quality is 15℃. for this
A thermoelectric cooler is built inside the sensor.
Sensor temperature can be controlled automatically/manually. In automatic mode, the Sensor Cooling Target set temperature (℃) is
Applies to Cooling. Voltage is controlled by comparing sensor temperature and case temperature in real time. Manual mode is
Regardless of the target temperature, the Sensor Cooling Voltage set voltage (V) is applied to cooling. both modes
The voltage applied to actual cooling can be checked in Sensor Cooling Applied Voltage. The default setting is
Same mode, target temperature is 15℃.
| Feature | Value | Description |
|---|
| Sensor Cooling Auto | Off | Enables or disables Sensor Cooling Auto. |
| On | |
| Sensor Cooling Target | 10 ~ 40
(Unit : ℃) | Sets the sensor target temperature. This setting is valid only when Sensor Cooling Auto is On. |
Sensor Cooling
Voltage | -6 ~ 6
(Unit : V) | Sets the voltage applied to sensor cooling. This setting is valid only when Sensor Cooling Auto is Off. |
Sensor Cooling

＊Sensor temperature and case temperature can be found in ‘Device Temperature Selector’ and ‘Device Temperature’ in the ‘Device Control’ category.
You can check. You can update the current temperature using the 'Temperature Update Feature'.
＊The case temperature displayed in 'Device Temperature' and the case temperature applied to the cooling algorithm are those of the camera's internal frame.
It's temperature.
＊Power consumption may increase depending on the degree of sensor cooling. Target temperature (automatic) considering power consumption and image quality
mode) or voltage (manual mode).
＊The maximum cooling range of the built-in thermoelectric cooler is 40℃. In automatic mode, the sensor temperature and case temperature
The target temperature is automatically adjusted so that the difference does not exceed 40℃. Therefore, the case temperature is 40℃ higher than the target temperature.
If it rises, the sensor temperature may also rise, and additional heat dissipation measures must be taken as necessary.
＊Heat generation may increase depending on the voltage applied to cooling. When setting voltage in manual mode, Sensor temperature and Case
Both temperature and ambient temperature must be considered.
