6.7 White-Balance Control

The White-Balance Control is used to adjust the gains of the individual color channels to correct for variations in the

color of scene illumination. The White-Balance Control is shown below:

The histograms give a graphic illustration of the spectrum of the image, showing what and how often specific colors

appear in an image. The mean of the histogram is displayed textual and as a white vertical line on the histogram. In a

well-balanced image of a white scene the histogram means should all be the same.

Pressing the Auto Balance button enables Auto White-Balance. Auto White-Balance modifies the individual color

channel gains to attempt to insure that the means of the histograms are all equal, thus insuring a well-balanced image.

The individual channel gains can be manual adjusted using the sliders on the White-Balance Control.

White Balance Control Panel

There are also 4 Simulated Film Speed buttons on the control. These buttons change the baseline gain on all color

channels to simulate a change in film speed. Increasing the simulated film speed increases the sensitivity of the camera,

but can cause increased noise in the image.

The B/W button tells the SharkEye™ application that an optional black and white image sensor is being used rather than

then standard color sensor.

6.8 Lens Control (optional)

The Lens Control Dialog can be displayed by selecting Windows/Lens Control from the main menu bar. The Lens

Control Dialog allows for the control of an optional motorized zoom lens in the SharkEye™ camera. The top row of

buttons controls the zoom of the lens. Pressing one of these buttons can set the focal length. The bottom row of buttons

controls the aperture of the lens. Pressing one of these buttons can set the f-stop of the lens.

Note: Lens control only works on SharkEye™ cameras equipped with a motorized zoom lens.
