    摘要： An adapter is provided for adapting an optical instrument, such as a camera (3) or a projector, to capture or display panoramic three-dimensional images. The adapter comprises a plurality of mirrors (1a, 1b, 1c), each of which has a reflective surface which is in the shape of a curved non-circular conic section rotated about an axis of symmetry (15a, 15b, 15c). The reflective surfaces have first foci which are spaced perpendicularly from a longitudinal axis of the adapter and which are angularly spaced around the longitudinal axis. For example, the conic section may be a hyperbola with first foci equidistantly spaced from the longitudinal axis and equiangularly spaced around 15b the longitudinal axis. The axes of symmetry (15a, 15b, 15c) of the mirrors (1a, 1b, 1c) converge to intersect the longitudinal axis at a point which is coincident with the front principal point of, for example, a camera lens (12). Thus, single shot capture of all the image data for the or each panoramic three-dimensional image may be performed.

    摘要： An autostereoscopic display comprises a pixellated transflective spatial light modulator which is arranged to provide a visual indication to an observer of the amount of crosstalk caused by reflection of ambient illumination. The display comprises a rear parallax barrier between a backlight and the modulator. Part of the barrier is formed as a screen blocking transmitted light from a first region of the modulator so that the pixels in this region are visible only by reflection of ambient illumination. In a second region, the pixels are illuminated with both transmitted and reflected light. A controller sets the pixels of the first region to maximum intensity and the pixels of the second region to a fraction of the maximum intensity. The fraction corresponds, for example, to a maximum amount of crosstalk which is permissible for autostereoscopic viewing. When the brightness of the first region is darker than or the same as the brightness of the second region, crosstalk is sufficiently low to permit autostereoscopic viewing.

    摘要： A method of rectifying a stereoscopic image consisting of left and right captured images comprises determining left and right rectification transformations. According to one aspect of the invention, statistics of the parameters of the stereoscopic image capture device used to capture the left and right images are used in the determination of the left and/or right rectification transformation.According to another aspect of the invention, the left and right rectification transformations are constrained to correspond to a transformation to a virtual alignment to a parallel camera set-up.Once the left and right rectification transformations have been determined they are preferably used to rectify the left and right images to eliminate, or substantially eliminate, vertical disparity from the rectified image pair. The left and right rectified images may then be displayed on a stereoscopic display device for viewing by an observer, or they may alternatively be stored for later use.

    摘要： An autostereoscopic display comprises an SLM which is controlled to provide an image display and a signal display. A parallax optic has a first portion which cooperates with the image display to form a plurality of viewing windows. A second portion of the parallax optic forms first and second images visible to an observer to allow the observer to distinguish between a desired orthoscopic viewing zone and undesirable viewing positions such as pseudoscopic positions. The pitch of parallax elements in the second portion is one and a half times the parallax element pitch in the first portion.

    摘要： A display device is provided that comprises a liquid crystal display panel (2) for displaying an image by spatial light modulation. The image is represented by a plurality of image elements each having an image data value (7). The display device further comprises a display controller (1) arranged to determine a signal voltage to be applied to the panel (2) for each image element in dependence upon its image data value (7) and a secondary data value (8) for the element, there being a predetermined mapping between the data values and the signal voltage. The secondary data values (8) are arranged to vary across the image so as to introduce variations in luminance as a result of the mapping. The mapping and secondary data values (8) are mutually arranged to take account of the signal voltage to on-axis luminance response of the panel (2) so that the luminance variations introduced on-axis tend to balance locally through spatial averaging to, and hence would not be perceivable by, an on-axis viewer (3). The panel (2) furthermore has a non-linear off-axis luminance to on-axis luminance relationship, so that at least some of the luminance variations introduced off-axis do not balance locally through spatial averaging to, and hence would be perceivable by, an off-axis viewer (4).
