1. A method of improving trackability of an object within a video image, comprising: determining whether camera settings cause saturation of the video image and hue differences between objects to be tracked and between the objects and a background of the video image to exceed a threshold; and if the saturation and hue differences do not exceed the threshold, searching the camera settings to find a setting that causes saturation and hue differences between objects and between the objects and the background of the image to exceed the threshold.
