Detailed Description

The LightingChangeTester checks if the lighting has changed.

To know this can be important for a color calibration system. The calibration system has to extract green pixels from the image. Each such pixel must be added using the method addColor. If a new image is processed startImage has to be called. The method lightingHasChanged returns true, if the lighting has changed.
