| Number | Title | Issue Date |
| 6426755 | Graphics system using sample tags for blur A graphics system and method for performing blur effects, including motion blur and depth of field effects, are disclosed. In one embodiment the system comprises a graphics processor, a sample buffer, and a sample-to-pixel calculation unit. The graphics p... | 07/30/2002 |
| 6100872 | Display control method and apparatus A display control method and apparatus for quantizes input data to binary or multivalued data and delivers the quantized data to a display device such as a matrix panel display. When input data is quantized as by the error-diffusion method and displayed, ... | 08/08/2000 |
| 6069609 | Image processor using both dither and error diffusion to produce halftone images with less flicker and patterns An image processing device has an error distribution unit, and a multiplier. The error distribution unit carries out an error distribution operation to artificially increase the number of shades to be displayed on a display. The multiplier multiplies an i... | 05/30/2000 |
| 5630036 | Image data compression method involving deleting data in areas where predicted color value, based on color change between adjacent pixels, is small, and image data processing device implementing same method An image data compression method in which reductions in data amount are achieved by deleting some pixel data. Compression is achieved by performing a reading step to read an image as plural pixel data and a deleting step to delete some of the pixel data. ... | 05/13/1997 |
| 5600763 | Error-bounded antialiased rendering of complex scenes An antialiased rendering algorithm that guarantees that each pixel of the output image is within a user-specified error tolerance of the filtered underlying continuous image wherein an object-space octree is used to cull hidden geometry rapidly, and a qua... | 02/04/1997 |
| 5570461 | Image processing using information of one frame in binarizing a succeeding frame An image processing apparatus eliminates problems encountered in binarizing processing when an A/D-converted multivalued frame image is entered continuously and the image is displayed continuously on a binary-image display device. In terms of binarizing p... | 10/29/1996 |
| 5481662 | Method of and apparatus for modifying base separation figure An original figure corresponding to a contracted white separation figure is extracted as an objective figure (step T2), and original figures adjacent to the objective figure are then extracted (step T3). When a white separation figure corresponding to a c... | 01/02/1996 |
| 5063375 | Method and apparatus for shading images The present invention provides unique methods and apparatus for shading curves, polygons and patches, implementing Phong, Gouraud and other shading techniques in the rendering of images on a cathode ray tube or other display device. The present invention ... | 11/05/1991 |
| 4878182 | Multiple pixel generator A system for generating multiple pixels in a single machine cycle employs a plurality of parallel vector generators. Each of the parallel generators is initialized with an error term which is calcualted in accordance with Bresenham's algorithm. The signs ... | 10/31/1989 |
