Appl. No.:

10/232791

Inventors:

William J. Allen - Corvallis OR, US
James R Cole - Albany OR, US
Brian S Dixon - Albany OR, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G09G 5/00
H04N 3/27

US Classification:

345204, 345699, 348558

Abstract:

Signaling a display device to automatically characterize a video signal is disclosed. In a method of an embodiment of the invention, a display device that has a video signal characterization circuit is signaled to automatically characterize a video signal of a video source. A predetermined characterization image is provided on the video signal of the video source for the display device to automatically characterize.

Appl. No.:

10/690784

Inventors:

Brian S. Dixon - Albany OR, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G09G 5/02

US Classification:

345591, 345589

Abstract:

A method for adjusting color of images displayed in ambient light. A signal may be sensed from a plurality of spectral regions of an ambient light source to define a sensed signature of the ambient light source. The sensed signature may be compared to predetermined signatures of candidate light sources to identify a candidate light source that corresponds to the ambient light source. Images may be created so that the images are modified by a predefined color adjustment for the candidate light source identified.

US Classification:

348744, 348602, 348742, 348759, 348760, 353 84

Abstract:

A display system is configured to produce a color image formed of a plurality of differently colored images and may include at least one light source that directs light along an optical path, and at least one filter having a given optical filter characteristic. The display system may be selectively operable in a first state in which the optical path does not pass through a first filter during production of the plurality of differently colored images to form a color image having a first optical characteristic, and in a second state in which the optical path passes through the first filter during production of the plurality of differently colored images to form a color image having a second optical characteristic different than the first optical characteristic.

Abstract:

A display system may include an identifier configured to identify an image display condition associated with the display of an image produced by the display system, an apparatus configured to produce a plurality of differently colored images, and a display device. The images have color characteristics based on image information and the identified display condition. Differently colored images may be directed along associated portions of an optical path. The display device may be coupled to the apparatus and may be configured to display a color image formed of the differently colored images.

Appl. No.:

10/423365

Inventors:

Brian Dixon - Albany OR, US
Peter Howard - Junction City OR, US
David Ochs - Corvallis OR, US

International Classification:

G09G005/00

US Classification:

345/001100

Abstract:

A method for color management in a display system based on perception. A plurality of images may be displayed to a viewer using an additive display device. Each image of the plurality may have a different color adjustment and at least two colors. An input may be received from the viewer selecting an image of the plurality based on the viewer's color perception of such image relative to other images of the plurality. Subsequent images may be displayed according to the different color adjustment of the image selected.
