Vision Processing Question

[Greg McKaskle]

Check to see how your camera's white balance is set. If it is set to auto, then it runs an algorithm that samples the image from time to time and tries to return an image that is balanced. For security or photography, that is a fine feature, but it messes with the actual colors returned. You probably want to turn it off and stick with a given white balance setting, or even the Hold setting. Another thing that will impact color to a lesser degree is the exposure, the amount of light that the camera receives. You may also need to calibrate and hold that.

The most important thing to learn from this is that lighting is not a constant, and that you should test it in different locations and learn how the camera reacts. You will either find the camera settings that are consistent, or you will become good at calibrating quickly and accurately. Either will pay off at the event(s).
