A vision system includes an image capturing arrangement for producing a plurality of first image signals of a scene based on electromagnetic energy received from the scene. A platform supports at least the image capturing arrangement for selectively positioning and repositioning the image capturing arrangement so that it images a series of different scenes. A memory is provided for storing scene-dependent parameters. At least one signal processor is operatively associated with the image capturing arrangement and the memory. The signal processor is configured to utilize at least one of the first image signals representing each of the scenes being imaged to adjust at least one image-capturing parameter to enhance image quality of the respective scene. The signal processor is also configured to utilize at least two of the first image signals received at different times that represent each of the scenes being imaged to generate, based on at least one predetermined criterion, a second image signal representing object motion arising in each of the scenes. The image-capturing parameter and the predetermined criterion are established on a scene by scene basis and stored in the memory for use by the signal processor upon imaging any given scene a subsequent time.
