A mirror assembly ( 18 ) for displaying an image ( 15 ) in conjunction with the reflection ( 14 ') of a viewer comprises a mirror ( 2 ), which is equipped with a reflective polariser ( 13 ), arranged to reflect light ( 3 ) incident on its viewing side and transmit light ( 4 ) incident on its non-viewing side, where the reflected light ( 3 ) and transmitted light ( 4 ) may be of different polarisation. The image ( 15 ) is displayed by a device ( 5 ) located on the non-viewing side and focussed by a focussing element, e.g. one or more lenses ( 12, 12 a), onto an image plane. The image plane may be located between the mirror ( 2 ) and viewer ( 14 ), so that a perceived image ( 15 ') appears to stand out from the mirror ( 2 ). Alternatively, the image plane may be located so that the perceived image ( 15 ') forms a background in which the viewer's reflection ( 14' ) is immersed. The mirror assembly ( 1 ) may further comprise one or more detectors ( 19 ) for obtaining a silhouette ( 21 ) of the viewer ( 14 ). The silhouette ( 21 ) can be subtracted from an image ( 15 ) to produce a modified image ( 24 ) for display by device ( 5 ), thereby avoiding competition between the perceived image ( 15 ') and viewer reflection ( 14 ).
