    摘要: An autostereoscopic display device comprising a view forming module in registration with an image forming means. The image forming means has an orthogonal array of display pixels spatially defined by an opaque matrix. The view forming module provides at least two optical functions, namely a view forming function and a brightness non-uniformity reducing function. The view forming function modifies the direction of outputs of the display pixels such that the outputs of groups of the display pixels are projected in respective different directions as a plurality of views. The view forming function is provided by an array of parallel lenticular lenses arranged across the view forming module and having a first pitch. The brightness non-uniformity reducing function spreads the outputs of the display pixels such that brightness non-uniformities caused by imaging of the opaque matrix are reduced. The brightness non-uniformity reducing function defines a second pitch across the view forming module less than the first pitch, and further defines an effective spreading angle in a plane perpendicular to axes of the view forming elements substantially equal to or less than the angle between adjacent views projected by the view forming function. The brightness non-uniformity reducing function is provided by an array of lenses or a diffuser. In the case of an array of lenses, these lenses may be integrated with the lenticular lenses providing the view forming function in the form of lenses having a polygonal cross section.

    摘要: There is disclosed a multi-view autostereoscopic display device comprising an image forming means arranged over and in registration with a view forming module. The image forming means has a planar array of light emissive display pixels arranged in rows and columns for producing a display, the display pixels being spatially defined by an opaque matrix. The image forming means may, for example, be a LCD display panel. The view forming module is configurable to function as a plurality of view forming elements arranged in the width direction of the display device, each view forming element focusing the light output from an adjacent group of the display pixels into a plurality of views for projection towards a user in respective different directions. The view forming module may, for example, be an array of lenticular lenses. The geometry of the view forming elements defines a substantially periodic inter-element variation in the width direction of the display device, for reducing brightness non-uniformities in the views. The inter-element variation may, for example, be provided by varying at least one of the widths, the focusing powers and the relative positions of the geometric axes of the lenticular lenses in the width direction of the display device.

    摘要: An image processing system generates an output image from an input image through a depth-dependent transformation. The images are represented as respective pixel arrays. An input 1110 receives for each input pixel an associated input pixel value and input pixel depth. Each input pixel is associated with a respective reconstruction filter footprint. A video processor create the output pixels by, for each input pixel, transforming 1120 the input pixel to a transformed input pixel as a function of the associated input pixel depth and transforming the associated filter footprint to an transformed filter footprint as a function of the associated input pixel depth. The processor also performs a reconstruction filtering operation 1150 on a plurality of the transformed input pixels using the transformed filter footprints. An output 1160 is used for providing the output image for subsequent rendering.
