    • Disclosed is a visual communication signal (32) which comprises image model information (10) for generating 3-D images. The image model information (10) may comprise a 3-D image model, e.g. a 3-D wireframe model or a 3-D voxel map. Some of the generated 3-D images may have a relatively low image quality. The visual communication signal (32) further comprises image enhancement information (20) corresponding to at least part of the 3-D images for enhancing the image quality of the generated 3-D images. This image enhancement information (20) may comprise image information corresponding to one or more single viewpoints (22,24) and/or image information corresponding to one or more ranges of viewpoints (26,28). The visual communication signal (32) may be transmitted from a transmitter (30) to a receiver (34) in a visual communication system (40) such as a 3-D television system or a 3-D teleconferencing system. Alternatively, the visual communication signal (32) may be carried by a tangible medium, e.g. a CD-ROM or a DVD-ROM.

    • 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, 12a), 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´).
    • 用于与观看者的反射(14')一起显示图像(15)的反射镜组件(18)包括配备有反射光(3)的反射偏振器(13)的反射镜(2) 在其观察侧入射并透射入射在其非观看侧的光(4),其中反射光(3)和透射光(4)可以具有不同的偏振。 图像(15)由位于非观看侧的设备(5)显示,并且由聚焦元件聚焦。 一个或多个透镜(12,12a)到图像平面上。 图像平面可以位于反射镜(2)和观看者(14)之间,使得感知图像(15')看起来从反射镜(2)中脱出。 或者,图像平面可以被定位成使得感知图像(15')形成观看者的反射(14')被浸没的背景。 镜组件(1)还可以包括用于获得观察者(14)的轮廓(21)的一个或多个检测器(19)。 可以从图像(15)中减去剪影(21)以产生用于由设备(5)显示的修改图像(24),从而避免感知图像(15')和观看者反射(14')之间的竞争。
