US Patent:

7134737, Nov 14, 2006

Filed:

Aug 31, 2001

Appl. No.:

09/945492

Inventors:

Ferran Vilanova - Barcelona, ES
Miquel Boleda - Barcelona, ES
James L. McCullough - San Diego CA, US

Assignee:

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

International Classification:

B41J 29/393

US Classification:

347 19, 358504

Abstract:

Absolute perceptual values are stored in the design lab, for maximum-density-tone cutoffs—preferably a maximum yellow-blue chrominance b* for yellow and minimum luminosity L* for other colorants. Automatic field operations in each printer then force the printer to subsequently print nominal full-saturation colorants so as to match the stored values. In addition to the stored cut-offs, black-and-white reference values measured in the printer are also used in linearizing printer response, for specific combinations of printing medium and printmode.

International Classification:

B41J 2/045

US Classification:

347 19, 347 14

Abstract:

PPS variation along a scan axis is found by shining a light beam from pen carriage to print-medium position and back to detector, and applying a pathlength/intensity correlation. Sensing is done while scanning, to find relative PPS profile along the track. With no medium in place this measures mechanical imperfections—and can be corrected by later deducting thickness of a medium. If medium is present, adjustment is omitted. For absolute values a plural-lamp sensor is calibrated for each lamp, at the PPS design point. Pagewide/webwide variants are included.

International Classification:

G06F 17/00
G06N 5/02

US Classification:

706 47

Abstract:

A system for creating an album is disclosed. In one embodiment, the system includes an image input configured to receive related images, an image memory coupled to image input, an image processor coupled to image memory, and an album output coupled to image processor. The image processor is configured to use game play with users to assign metadata labels to the related images and assign album layout rules based upon the story schema and metadata labels.

International Classification:

G06F 17/30

Abstract:

An example processor-implemented method for retrieving multimedia data in accordance with the present disclosure is determining whether each of a plurality of still frames satisfies at least one trigger qualification process for a trigger generation process, presenting for selection still frames from the plurality of still frames if the still frames satisfy the at least one trigger qualification process for a trigger generation process, receiving a selection of a still frame from among the presented still frames, and performing the trigger generation process on the selected still frame to generate a trigger for the selected still frame.
