Appl. No.:

09/876513

Inventors:

Theodore Mayer, III - Valley Village CA
Su Wen Wang - Walnut CA

Assignee:

Panoram Technologies, Inc. - Sun Valley CA

International Classification:

H04N 566

US Classification:

348383, 348745, 345 13, 353 30

Abstract:

Method and apparatus are provided for seamless integration of multiple video projectors. In addition to edge blending, projection artifacts in dark or black image regions caused by residual grays from non-perfect projector black levels are reduced. Overlapped and non-overlapped areas of the image are defined and then the minimum black level of the video signal in non-overlapped areas is boosted without affecting the bright portion of the video signal in order to create uniform black level. The bright portion of the image is then smoothed in the overlapped area with seamless edge blending techniques. The resultant projected image may be passed through a neutral density filter to lower the base black level of the now uniform overlap and non-overlap black regions. The image may also pass through a physical mask which is hard edged or graded and aligned to less than the overall overlap region and that when used, smooths the edge of transition between the non-overlapped and overlapped regions.

Abstract:

A process of configuring a media facility is provided. A source icon representing at least one media source is generated. Then, characteristics of the media source is encrypted in the source icon including settings and recalls for all devices in the signal path. Further, a media space representing an output device is generated. Then, characteristics of the output device is encrypted in the media space. The source icon and the media space are presented, for example, on a display system, to a user for selection. The user may select the source icon and apply it to the media space including settings and recalls for all devices in the signal path, for example, through dragging and dropping. Once the media source, the output device and/or other devices in the signal path between them have been configured, the user may store the configuration for a later recall.
