An imaging apparatus and method are provided for improving discrimination between parts of a scene enabling enhancement of an object in the scene. A camera unit (12) is arranged to capture first and second images from the scene (8) in first and second distinct and spectrally spaced apart wavebands. An image processing unit (14) processes the images so captured and processes polarimetric information in the images to enable better discrimination between parts of the scene. An image of the scene, including a graphical display of the polarimetric information, may be displayed on a visual display unit (16) thus enhancing an object in the scene for viewing by a user. Correlation parameters indicating, possibly on a pixel-by-pixel basis, the correlation between the actual image intensity (30) at each angle of polarisation and a modelled expected image intensity may be used to enhance the visibility of an object.
