1. Imaging apparatus for improving discrimination between parts of a scene, wherein the imaging apparatus comprises 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, the image processing unit is arranged to use the polarimetric information to enhance the image of the scene displayed by the visual display unit so as to provide better discrimination between parts of the scene, the enhancement added by the image processing unit being controllable by a user.
