Thermal Sensor Settings

Opacity

Sets the opacity of the thermal overlay image. The lower the value, the more of the background (i.e., the image of the optical image sensor) will show.

Scaling

Sets the scaling of the thermal overlay image. You can change this value to adjust the thermal overly image to the focal length of the optical image sensor.

Horizontal Offset

Use this parameter to move the thermal overlay image in horizontal direction (based on 1280x960 pixels). Positive values move the overlay image to the right, negative values to the left. 0 centers the image, the maximum value is ±640.

Vertical Offset

Use this parameter to move the thermal overlay image in vertical direction (based on 1280x960 pixels). Positive values move the overlay image up, negative values down. 0 centers the image, the maximum value is ±480.

Overlay Mode

Color Palette

Sets the color palette that is used to show the different temperatures in the thermographic image.

Show Color Palette

Displays the current color palette at the bottom of the image. The leftmost color of the palette corresponds to the lowest, the rightmost color to the highest temperature in the image.

Linear Mode

The linear mode allows using extended radiometry features (Thermal Radiometry event). Note that activating this option influences the colors of the live image.

Manual Temperature Adjustment

Getting precise temperature readings from the thermal sensor is only possible, if all variables and disturbances are known. Since they influence the measurement, you can then add a corresponding offset.. By factory default, the camera has been calibrated so that it properly measures the temperatures for objects with a maximum emission ratio in the close-up range. If these basic conditions are not met, you can improve measurement accuracy by manually adjusting the following parameters (if the manual temperature adjustment is deactivated, the factory default settings are used).

Value Range

Sets the value range of the displayed temperatures, i.e., the range between the lowest and the highest temperature that is to be displayed. A small value range results in noticeably higher sensitivity (i.e., the smallest difference in temperature that can be shown) compared to a large value range.

Automatic Adjustment

Automatically determines the minimum and maximum temperature values for color mapping. Deactivate automatic adjustment if you want to set custom limits.

Allow Immediate Updates

Activates immediate updates of the minimum and maximum temperature values in the color palette if the temperatures of the scene changes drastically. Deactivate immediate updates to get a continuously adapted color palette even when temperatures changes are large.

Update Speed

Sets the speed with which the minimum and maximum temperature values in the color palette are adjusted to the changes in temperature of the scene.

Level of Detail

Controls the contrast amplification of a thermal image. This is especially useful when there are only little differences in temperature in the image; selecting Medium or High will enhance contrasts, thus showing noticeably more image details.

Temperature Control Mode

Full Image Area: All pixels of the full image or the defined temperature control windows are used to determine the current thermal range.

Visible Image Area: Only the pixels of the visible image section are used to determine the current thermal range.

Temperature Windows

Temperature control windows are defined image areas that are used for automatic adjustments. To facilitate the positioning of temperature control windows, you can select from a number of pre-defined windows.

Show Windows

On: Displays the defined measurement window(s) with green frames in the image. Exclusion windows are shown with a red frame.

The Histogram option shows additional parameters of specific image processing features in the image.
