摘要： 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.

摘要： A switchable autostereoscopic display device comprises a display panel having an array of display pixel elements for producing a display, the display pixel elements being arranged in rows and columns. An imaging arrangement directs the output from different pixel elements to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement is electrically switchable between at two 3D modes, wherein the effective position of the imaging arrangement is shifted laterally between the modes with respect to the display pixel elements by an amount which is a non-integer multiple of the pitch between the pixel elements. These two modes enable the resolution per mode to be increased, by adding views at inter-pixel locations, or enables the number of views to be increased.

摘要： A multi-view autostereoscopic display device comprises: a backlight having a plurality of backlight areas arranged in a width direction of the display device; a spatial light modulator arranged over and in registration with the backlight, the spatial light modulator having an array of display forming elements arranged in rows and columns for modulating light received from the backlight; and a view forming layer arranged over and in registration with the spatial light modulator, the view forming layer having a plurality of view forming elements arranged in the width direction of the display device, each view forming element being configured to focus modulated light from adjacent groups of the display forming elements into a plurality of views for projection towards a user in different directions. The backlight is switchable to activate different ones of the backlight areas in different portions of a driving cycle of the display device so that, in the different portions of the driving cycle, modulated light from the active backlight areas is incident on each view forming element with respective different angles of incidence. In this way, the overall viewing angle or the effective three dimensional display resolution may be increased.
