### White Balance

In smart cameras that support color images, White Balance automatically evens out the gain values of red, green, and blue channels so the camera image will look the same as it does to the human eye. White will become white even if the lighting is not.

Example: The image prior to White Balance has a greenish color. The red, green, and blue histograms are not balanced.

The image after White Balance has no greenish color. The red, green, and blue histograms are balanced.

A toolbar in the Image view contains buttons for Auto Calibration, White Balance, Restore Factory White Balance, and, for Auto Focus cameras only, a Quick Focus button (not shown here). White Balance and Restore Factory White Balance buttons are only visible for color cameras.

Auto Calibrate button:

White Balance button:

Clicking this button will launch the Auto White Balance operation:

Restore Factory White Balance button:

Clicking this button will restore the white balance settings to factory defaults.

##### Color Image Display

Images are displayed in full color. Moving the mouse pointer over a pixels in a color image will display the RGB and HSI values of the current pixel.

##### Color Plane Display for Non-Color Tools

AutoVISION allows you to insert any of the standard tools into a color image (Count, Presence/Absence, Measure, etc.). These tools do not operate on color pixels, but they do operate on one of the monochrome color planes (typically luminance). The color plane is only displayed within the region of interest of the selected tool. The Count Tool is shown in this example:

The overall image remains in color, but within the region of interest of the Count Tool, the monochrome pixels being operated on are shown.
