Objective:		Examination of objects with fluctuating exposure. We recommend
		to avoid this situation if possible because changes in the exposure
		make the application more unstable.

          ť 'Average Brightness'
          ť 'Delta Brightness'
          ť 'Update Reference Value'
          ť Window checker
          ť Creation of the exposure adjustment dependency
          ť Examination with a different brightness
          ť Changed 'Delta Brightness'
