A multi-dimensional image data enhancement system is configured to reduce the effect of blanking areas on the large kernel processing of pixel data. Thus, when pixels comprising blanking data are processed, additional blanking data can be added to the blanking data such that the additional 'fictional blanking data' will occupy an area within the kernel size instead of image data in an adjacent frame or non-related areas of the current frame.

A method and system are disclosed that correct pixel values for output on a video display utilizing gamma correction. The method provides improved gamma correction by determining a first range of pixel values to be displayed on the video display and then determining a second range of pixel values to be displayed on the same display. Next, the method determines a first level of gamma correction to be provided for the first range of pixel values. This first level of gamma correction is provided at a first level of precision. Next, the method provides a second level of gamma correction to the second range of pixel values at a second level of precision. The second level of precision is different than that of the first level and is typically less than the first level.

Video display system utilizing gamma correction

A procedural solid texturing system which uses a parameterized function capable of reproducing the most common procedural solid textures, specifically wood, marble, clouds and fire ( ). This model is simple enough to be implemented in hardware, and can be realized in VLSI with as little as 100,000 gates. The invention also includes a method for antialiasing the parameterized procedural textures ( ). The antialiasing includes an expression for the necessary box filter width, a technique for efficiently box filtering the procedural texture by either MIP mapping the color table or using a summed area color table ( ).

A device for improving pixel rendering performance in a computer graphics system. The device includes a pixel resolution buffer containing a plurality of pixel storage locations to store pixel values. A depth value is provided for each pixel storage location in the pixel resolution buffer, to store a closest depth for polygons that cover the pixel. A subpixel resolution buffer is also included with a least two subpixels corresponding to each pixel storage location in the pixel resolution buffer.
