  • High contrast image apparatus employing optical filters to cause each image pick-up element to have its maximum sensitivity in a different spectral range
    Patent number: 5132802
    Abstract: To obtain high contrast images of objects which are in an area covered with rich vegetation and which additionally are given a camouflage coating, the wavelength specific differences in reflection behavior of the clutter and of the camouflage coating of the object are utilized. For this purpose, the apparatus according to the invention includes at least two image pick-up elements, particularly CCD cameras, whose output signals are fed to a signal processing arrangement whereby are combined. On the side of the object, respective optical filters are disposed in front of the image pick-up elements so as to cause each image pick-up element to have its maximum sensitivity in a different spectral range.
