In the "Color" dialog, adjust the white balance, color gain, and color correction.

Click on in the toolbar to open the dialog.

Auto features

Depending on the camera model, the functions can be executed directly in the camera or on the host PC. Use the radio buttons to switch between running on the camera or on the host.

Auto white balance

Here, you set whether the white balance should be performed permanently or only once.

•Off: Deactivates the automatic white balance.

•On: The camera adjusts the white balance continuously.

•Once: The camera adjusts the white balance once.
Point the camera to a white surface and enable "Once". The white balance setting is saved. After the adjustment, the setting returns to the "Off" state.

•Skip frames
Here, enter the number of frames that will be skipped in freerun mode for auto control. The higher the frame rate, the higher the value should be. If the value is too small, the control may starts to oscillate, or the system may be overloaded. Increase the value in this case.

ROI for auto white balance

You can either set the ROI with the camera image ROI or set it separately. Set the ROI for the camera image first and then set the ROI (see “Position and size” dialog).

1.Click to open the settings for the ROI. The ROI is bound to the camera image ROI by default.

2.Click on to set the ROI separately from the camera image ROI.

3.Click on to display the ROI in the camera image.

4.You can set the ROI via the Width and Height sliders and then move the ROI via X/Y offset. The ROI must be within the camera image ROI (see Sub-regions for auto-algorithms (Exposure, Gain, BalanceWhite, Autofocus)).

5.Or click on to draw the ROI directly in the camera window with the mouse.

6.To reset the ROI, click on .

Red, Green, Blue

Here, you set the gain of the individual color channels. Depending on the model, this is either analog or digital gain (if the model does not offer analog gain).

•Red/Green/Blue
Set the gain of the respective color channel using the slider or enter the value directly in the input field behind the slider.

For color cameras, we recommend setting the green gain to the minimum value and using only the red and blue gains. You can display the intensity line for assistance. In this window the color values of a pixel line are displayed graphically.

Color correction host / color correction camera

You use this to control whether a color correction matrix is used to optimize color reproduction. Depending on the camera model, the color correction can be executed directly in the camera or on the host PC.

•Auto: Enables color correction.
Color correction on the camera is enabled if the source pixel format is a debayered color format. Color correction in the host is enabled if the target pixel format is a debayered color format. Color correction is not available for RAW Bayer formats.

•Off: Disables color correction.

Color correction matrix

Via the drop-down list, you can choose between predefined and own color corrections, see Color correction. If you select the "custom0" setting, you can use the matrix below to adjust the color correction for your application.

The following formula is used for calculation:

Therefore, for an own color correction, the color correction matrix must be filed with the nine values for color correction.

Saturation

You can use the switch to enable control of color saturation during post-processing on the host. This allows fine-graded amplification or attenuation of the color saturation. Use the slider to increase or decrease the color saturation. The factor 2.0 corresponds to a value of 200 %. The default value is 1.0 (100 %).
