1. An imaging apparatus for discrimination between parts of a scene, the imaging apparatus comprising: at least one camera arranged to capture a first image from the scene at a first region of wavelengths, corresponding to a first waveband, and a second image from the scene at a second region of wavelengths, corresponding to a second distinct waveband; an image processing unit for processing the images so captured; and a visual display unit, wherein: the visual display unit is configured to display an image of the scene; the imaging apparatus is so arranged that the images detected by the at least one camera include polarimetric information that can be extracted by the image processing unit; and the image processing unit is arranged to extract polarimetric information from both the first and second images and to produce a third image of the scene for display by the visual display unit, the third image comprising complementary information from the polarimetric information extracted from both the first and second images, the complementary information, when displayed by the visual display unit, providing discrimination in the third image between parts of the scene.
