Title: Tiled, flat-panel displays with color-correction capability
Inventor: GREENE RAYMOND G
IPC: G06F3/14
Filed: 1997-03-25
Abstract: The present invention features a tiled, flat-panel, color display (20) that has a color-correction capability (24). The display is a tiled mosaic of individual display tiles (22), such as AMLCDs. Column and row inputs that are typically provided for a single display tile system are distributed over a plurality of display tiles. The color purity is achieved for the display by sorting the tiles into groups, matching their color coordinates, and correcting non-uniformities optically (e.g., by using a graded neutral density filter (28) having a grading function being the inverse of the brightness distribution non-uniformities) and/or electronically. Then, each individual tile in the mosaic is color-corrected via a multiplexed controller/driver circuit (12).

IPC: G06T15/50
Filed: 1998-01-20
Abstract: A system and method of determining, and subsequently using in a rendering engine, an illumination map. The illumination map is employed by the rendering engine to avoid having to calculate the contributions of lights in the scene during rendering, thus reducing the rendering time. In one embodiment, the system and method is used to determine the illumination values from the contribution of one or more lights to one or more texture mapped objects. This illumination map can either be stored independently of the texture picture to be mapped or can be combined with the texture picture to obtain an illuminated texture picture for subsequent rendering independent of the light sources. In another embodiment, the present invention is used to determine the illumination values for one or more objects represented by a polygon mesh. This illumination map can be stored independent of the material and color of the object or can be combined with the color and material information and stored in the object definition. In either of these cases, this illumination map represents the illumination values at the vertices of the polygons, the rendering engine and/or hardware linearly interpolating the remainder of the rendering information for each polygon. The illumination values can be determined either by summing the contribution of the lights in a scene at points of interest or by evaluating the entire shade tree defined for the scene at those points of interest. In this latter case, the contributions of reflections, refractions, transparencies and any procedural functions defined for the scene are considered in determining the illumination values. Evaluation of the entire shade tree also allows other options, such as the ability to generate 2D textures from procedural 3D textures or to generate a texture that contains the result of a blending between multiple textures.

Title: Filter structure and method
Inventor: LARSSON PATRIK
IPC: G06F17/10
Filed: 1998-08-19
Abstract: Multiported register files are employed to implement the input delays necessary for finite impulse response (FIR) filter operation. A multiported register file is a memory, typically small, with at least one read port and one write port. Data written into the multiported register file may be read out therefrom in anydesired order. The multiported register file may have additional output ports from which the data stored therein may be read out, also in any desired order, and independent from the order of any other output port. At least one output of eachmultiported register file is coupled to the input of the next stage of the FIR filter, if any. In addition, each multiported register file feeds data from one output to the multiply-add portion of its associated stage of the FIR filter. When the introduction of at least one sample delay for a particular sample is necessary, the multiported register file storing that sample is operated to supply, as an output, data that was previously stored therein, regardless of any data currently being supplied to it as input. In contrast, when no sample delay is required for a particular sample to reach a particular multiported register file, the multiported register files in the path of that sample are operated in a lookthrough mode. The read and write addresses, as well as the write enable signals for each multiported register file may be supplied in apipelined manner.
