Abstract: A method for reducing scintillation in an image of a scene includes receiving an input sequence of images of the scene and grouping a first plurality of images of the sequence of images into a first subset of images comprising a first number of images that occur in sequence within the input sequence of images of the scene. The method also includes grouping a second plurality of images of the sequence of images into a second subset of images comprising a second number of images that occur in sequence within the input sequence of images of the scene. The method further includes generating a set of averaged images comprising an averaged image for the first subset of images and an averaged image for the second subset of image and outputting a composite image based at least the set of averaged images.

Abstract: Anisotropically mapping of texture information to each pixel required for display of each of plural polygons forming each scene on a CIG display in a computational efficient manner, uses the footprint of each transformed pixel silhouette, as mapped from image space into the texture array, to determine an anisotropic texture space area having both a related length and a related width, in which complete texels and texels fractions are covered by that pixel footprint. A set of un-normalized line equations characterizing a particular pixel footprint is used to determine whether each texel or subtexel in the vicinity of that pixel footprint is either enclosed or avoided by (i.e. inside or outside of) that projected pixel footprint.

Abstract: The total illumination of each pixel to be displayed by a real-time computer image generator, is determined for at least one source illuminating a scene to be displayed, by storing in an observer depth buffer data signals representing those portions of object polygons visible to the observer in each pixel of the display, and storing in a source depth buffer, associated with each of the at least one scene-illuminating light sources, data signals representing illumination intensity received by each polygon pixel viewable from that associated source. A data signal, for each displayable pixel in the observer depth buffer, is generated by combining in non-saturating manner the illumination intensity of each light source impingent upon the equivalent pixel in all of the associated source depth buffers.
