US Patent:

20070211074, Sep 13, 2007

Filed:

Mar 17, 2005

Appl. No.:

10/593195

Inventors:

Raymond Yeung - Los Angeles CA, US

Assignee:

TECHNICOLOR INC. - NORTH HOLLYWOOD CA

International Classification:

G09G 5/02
H04N 1/60
H04N 9/11

US Classification:

345604000

Abstract:

The invention provides a color processing system comprising an image capture device for capturing a scene and providing first color image data representative of the scene. A color space transformer is coupled to the image capture device for transforming the first color image data to second color image data. A first display device is coupled to the color transformer. The first display device displays the scene as represented by the second color image data. The color transformer includes a processor programmed to perform a matrix operation upon the first color image data by selecting matrix elements from a look up table (LUT) comprising pre-computed values.

International Classification:

H04N 9/64
H04N 5/781

US Classification:

348708, 386126, 348E09037

Abstract:

A method and system for determining correction information for the universal display of an original video sequence on a plurality of displays includes correcting an original video sequence using a first display, storing correction information related to the correction of the original video sequence using the first display, correcting the original video sequence using a different display, and determining and storing the differences between the correction information related to the correction of the original video sequence using the first display and using a particular, different display. Subsequently and prior to the display of the original video sequence, the original video sequence is corrected using a combination of the stored correction information related to the correction of the original video sequence using the first display and the respective determined differences, if any, related to a particular, different display on which the original video sequence is now to be displayed.

International Classification:

G11B 27/30
H04N 9/82
G11B 27/34
H04N 5/14

Abstract:

Methods and systems for generating and applying scene-stable metadata for a video data stream are disclosed herein. A video data stream is divided or partitioned into scenes and a first set of metadata may be generated for a given scene of video data. The first set of metadata may be any known metadata as a desired function of video content (e.g., luminance). The first set of metadata may be generated on a frame-by-frame basis. In one example, scene-stable metadata may be generated that may be different from the first set of metadata for the scene. The scene-stable metadata may be generated by monitoring a desired feature with the scene and may be used to keep the desired feature within an acceptable range of values. This may help to avoid noticeable and possibly objectionably visual artifacts upon rendering the video data.
