20090102855 | SUBPIXEL RENDERING FILTERS FOR HIGH BRIGHTNESS SUBPIXEL LAYOUTS - A display system comprises a display panel substantially comprising a subpixel repeating group tiled across the panel in a regular pattern. The subpixel repeating group comprises at least one white subpixel and a plurality of colored subpixels. The display system further comprises input circuitry configured to receive input image data indicating an image for rendering on the display panel, and subpixel rendering circuitry configured to compute an output luminance value for each subpixel of said display panel. The subpixel rendering circuitry multiplies data values of a spatial portion of the input image data by at least one image filter kernel which comprises a matrix of coefficients arranged such that each coefficient represents a fractional part of one of said data values of said spatial portion of said input image data. The subpixel rendering circuitry is further configured to sharpen the output luminance values using a luminance signal. | 2009-04-23 |

20090102857 | ANTIALIASING OF TWO-DIMENSIONAL VECTOR IMAGES - Described is a method of rendering an image. A transparency of a destination pixel and a transparency of a source pixel are determined at multiple sample positions in each pixel. A new pre-multiplied color is determined for the destination pixel in response to the transparencies of the destination pixel, the transparencies of the source pixel, a color of the source pixel and a pre-multiplied color of the destination pixel. New transparencies of the destination pixel are determined at the samples in the destination pixel in response to the transparencies of the source pixels and the transparencies of the destination pixel. The method of the present invention permits rendering of polygonal two-dimensional images while eliminating overdraw, therefore using less memory bandwidth than conventional methods for rendering typical two-dimensional vector images. Thus the method is suited for mobile computing and other applications with limited memory bandwidth. | 2009-04-23 |
20090102858 | VIRTUAL SPOTLIGHT FOR DISTINGUISHING OBJECTS OF INTEREST IN IMAGE DATA - Assistance systems are increasingly being used to assist vehicle drivers when driving their vehicles. To this end, a camera is used to record image data from the area surrounding a vehicle, and at least some of the image data ( | 2009-04-23 |
