Filed:

Apr 9, 2002

Appl. No.:

10/119591

Inventors:

Terrence J. Coleman - San Diego CA
Ken George - Bluffdale UT

Assignee:

Evans Sutherland Computer Corporation - Salt Lake City UT

International Classification:

G09G 500

US Classification:

345613, 345614, 382269

Abstract:

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.

Abstract:

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.
