8237779, Aug 7, 2012

Filed:

Apr 4, 2008

Appl. No.:

12/062761

Inventors:

Stephen W. Marshall - Richardson TX, US
Michael David McCormick - Allen TX, US
Henry William Neal - Allen TX, US
Stanford Porter Hudson - Dallas TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H04N 13/04

US Classification:

348 51, 348 42, 348 46

Abstract:

Video signals in a video stream are encoded by inserting reference signals in the video stream such that the encoded video stream carry both reference signals and video signals being coded. In the decoding stage, reference images generated from the reference signals are detected and used for identifying the encoded video signals based upon the profiles of the detected reference images. An imaging architecture capable of using the coding scheme comprises a shutter that can be implemented as a dual-processor configuration.

International Classification:

G06T 15/00

US Classification:

345419

Abstract:

A method is provided for animating a three-dimensional object using an animation rig. An exemplary method according to the invention is a method that defines a positional relationship between the location of one or more known points on first surface and an equal number of corresponding points on a virtual surface, and a time interval. The time interval is incremented, and the positional offsets of one or more known points on the first surface are determined. The corresponding point or points on the virtual surface are then transformed by the positional offset, and the change in animation rig control values for the transformed points on the virtual surface are calculated. The animation rig control values are then updated based on said calculations.

International Classification:

H05B 33/08
H02J 7/00
G02B 27/01

Abstract:

For controlling a level of luminance produced by a color light-emitting diode (LED) array, a method includes: for a predetermined flux bit-slice period, activating a color enable signal to select a primary color LED and to select a predetermined light flux magnitude set-point; selectively charging an energy storage device and discharging the energy storage device through the selected primary color LED to generate a light flux output during the flux bit-slice period; adjusting a rate of selectively charging the energy storage device to maintain a magnitude of the light flux output at the predetermined light flux magnitude set-point during the flux bit-slice period; and adjusting the predetermined light flux magnitude set-point over the life of the selected LED as the selected LED ages as a function of an anode-to-cathode voltage drop across the selected LED for a given magnitude of current flowing through the selected LED.

International Classification:

G02B 27/01

US Classification:

359630, 315210, 307 66

Abstract:

Light flux levels sensed from a color LED array control both current availability to the array and disable/re-enable a current bypass switch to shunt stored-energy current to or away from a selected LED. In continuous mode, a single flux pulse is created for the duration of a pre-established period. Feedback from the flux sensor pulses current to an energy storage device to maintain the light flux at a predetermined set-point. A particular dimming level is achieved by establishing both the pulse period and the flux magnitude. In discontinuous mode, one or more short flux pulses are created. Both the turn-on and the turn-off time of each flux pulse is controlled by alternately removing and then re-establishing a current shunt from the energy storage device to ground. Flux pulse magnitude is controlled by recognizing when the flux pulse has reached a predetermined set-point and re-establishing the current shunt to abruptly turn off current to the selected LED.
