1. A method of improving trackability of an object within a video image performed by a processor, the method comprising: loading prior camera settings that were previously used and stored if the prior camera settings are available; and if saturation and hue differences between objects to be tracked and between the objects to be tracked and a background of the image do not exceed a threshold, searching the prior camera settings to find a setting that causes the saturation and hue differences between the objects to be tracked, and between the objects to be tracked and the background of an image to exceed the threshold.
