A Procedure for Setting the Color
Enhancements

When setting the color enhancements on the camera, we recommend using the procedure outlined
below.

1. Arrange your camera so that it is viewing a scene similar to what it will view during actual

operation. Make sure that the lighting for the scene is as close as possible to the actual lighting
you will be using during normal operation. Using lighting that represents your normal operating
conditions is extremely important.

We recommend including a standard color chart within your camera’s field of view when you are
adjusting the color enhancements. One widely used chart is the ColorChecker® chart (also
known as the Macbeth chart).

2. Set the exposure auto, gain auto, and balance white auto functions to Off.

3. Reset the white balance by setting all BalanceRatio parameter values to 1.

4. Make sure the settings for gain and black level are at their minimums.

5. Set the LightSourcePreset parameter to the value that is most appropriate for your lighting. For

example, if you use tungsten incandescent light, select the Tungsten2800K light source preset.

6. Begin capturing images and check the basic image appearance.

7. Set the exposure time, black level, and gain so that you are acquiring good quality images. It is

important to make sure that the images are not overexposed. Overexposure can have a
significant negative effect on the fidelity of the color in the acquired images. Generally, the
settings for black level and gain should be as low as possible.

8. Adjust the white balance. Make sure a white or light gray object is imaged while white balance

is carried out. An easy way to set the white balance is to use the Once mode of operation on
the camera’s Balance White Auto feature.

9. If necessary, set the gamma value. When gamma is set correctly, there should be a smooth

transition from the lightest to the darkest gray scale targets on your color chart or on a gray
scale.

10. If necessary, fine-tune the colors and tonal values by adjusting brightness, contrast, hue, and

saturation.

11. Examine the colors and see if they are satisfactory at this point. If not, restart from step 3.

.

The procedure aims at producing a color reproduction on a monitor that is
optimized for human vision. The optimum for machine vision may require different
color enhancement settings.

To set the color enhancements:

Certain conditions outside the camera, such as the lighting, the camera lens, filter,
or the monitor settings are relevant to the reproduction of color in the image. If you
change any of these conditions, you will have to repeat the above procedure to
preserve optimum color reproduction.
