Kevin W Andresen, Kok S Chen: Method and system for rendering overlapping opaque graphical objects in graphic imaging systems. Apple Computer, Burns Doane Swecker & Mathis L, July 31, 2001: US06268859 (110 worldwide citation)

Objects in an image are rendered in a manner which dynamically avoids the rendering of obscured objects. Data pertaining to one object is stored in a designated memory location, such as a cache memory. Data for a subsequent object is compared with the stored data, and the area of intersection betwee ...

Kevin W Andresen: Image generation with dynamically consolidated list of image data. Apple Computer, Burns Doane Swecker & Mathis L, February 4, 1997: US05600768 (42 worldwide citation)

In an image generating device, descriptions of objects which constitute an image are stored in an intermediate form in a display list. The data which describes the objects is stored in an plurality of lists, where each list is related to a region of the image. To create each list, objects that appea ...

Kevin W Andresen, Robert C Fishman, Ted W Walker: Method and system for rendering achromatic image data for image output devices. Apple Computer, Burns Doane Swecker & Mathis, August 19, 1997: US05659407 (17 worldwide citation)

To reduce rendering time for an image to be generated, an image to be generated, such as a page of a document, is divided into non-overlapping regions. Within each region, a determination is made whether all of the data contained therein is achromatic. If so, achromatic data is rendered for a single ...

Kevin W Andresen, Allen M Chan, Robert C Fishman, Ted W Walker: Method and system for selectively rendering image data in a bi-level or multi-level format. Apple Computer, Burns Doane Swecker & Mathis, October 21, 1997: US05680526 (7 worldwide citation)

An image to be generated is analyzed to determine whether it is comprised solely of bi-level color data. If so, an indication is provided to a rendering device that a simpler rendering procedure, suitable for bi-level data, can be employed. However, full color information pertaining to the image is ...

Kevin W Andresen, Kok S Chen: Conversion of output device color values to minimize image quality artifacts. Apple Computer, Burns Doane Swecker & Mathis L, May 27, 2003: US06571011 (7 worldwide citation)

Undesirable artifacts appearing in color images, such as blooming or smudging around the edges of text, are avoided through selective reduction of the color gamut for objects which form the image. Individual component color values are modified by taking into account combinations of colors and their ...
