US Patent:

53070550, Apr 26, 1994

Filed:

Jul 6, 1992

Appl. No.:

7/908937

Inventors:

Herbert B. Baskin - Berkeley CA
Joseph A. DuVivier - Oakland CA
Eugene Sanders - Oakland CA

Assignee:

General Parametrics Corporation - Berkeley CA

International Classification:

G09G 302

US Classification:

345 1

Abstract:

A method for controlling a system for presenting to an audience images on a primary display or displays that incorporates a auxiliary monitor. The auxiliary monitor may be used in a variety of ways to assist in the presentation of information on the primary display. The preferred embodiment of the present invention contains a hand-held display control including an array of key switches providing control of the main monitor and an auxiliary monitor allowing the operator to view any one of several options. These options include a duplicate of the image being displayed on the main monitor, the next image to be displayed on the main monitor, any other image available from the image generator, a list of the images available from the image generator, and notes associated with each image or with the entire presentation.

International Classification:

G06F 1562

US Classification:

364521

Abstract:

A method and apparatus for assigning color values (or gray scale) to picture display locations. A large frame buffer is written into with each memory location (preferably one bit) corresponding to a separate element of an image. The frame buffer contents are then mapped into a smaller space. The frame buffer memory has a color value assigned to each location of the memory. The memory has a larger number of locations than the number of color picture display locations. Each location is also assigned one of a plurality of weights. A number of color patterns are created and stored, with each color pattern being a bit pattern designed to produce the desired color when applied to the color values of the memory locations. A representation of a desired image is written into the memory using the color patterns, with each memory location corresponding to a separate element of the image. A group of bits in adjacent memory locations are combined with their weighting factors to produce each color value for each color picture display location.

International Classification:

G09G 128

US Classification:

340703

Abstract:

A high resolution, multicolor frame buffer memory and sequential read/write logic provides high speed access and reduced memory requirement for a scanning display. Frame buffer memory bits are assigned corresponding display location color values according to a selected pattern and color distribution scheme. Current display locations and neighboring display locations, including subsequent and/or preceding display lines, are examined to assemble color information for each current display location, such that a plurality of color values are combined for each display location, even though the frame buffer memory only stores one color value for each display location.
