Abstract

Apparatus comprising framestore demultiplexing means (32) for creating a specific area of interest which has a higher image update or frame rate than a surrounding area (FIG. 7). The apparatus may be used in simulators such as flight simulators, air traffic control simulators, and driving simulators.

Claims

1. Apparatus comprising framestore demultiplexing means for creating a specific area of interest which has a higher frame rate than a surrounding area.

2. Apparatus according to claim 1 and including tracker means for use with the framestore demultiplexing means.

3. Apparatus according to claim 2 in which the tracker means is a head slaved tracker means.

4. Apparatus according to claim 2 and in which the tracker means is for tracking the specific area of interest.

5. Apparatus according to claim 1 and including a high speed video switcher for use with the framestore demultiplexing means in order to create the specific area of interest.

6. Apparatus according to claim 1 and including a video switch that selects data at sub-frame level from image sources that may update at different but synchronous rates.

7. Display apparatus comprising apparatus according to claim 1.

8. Display apparatus according to claim 7 and which is a large array display apparatus.

9. A simulator comprising display apparatus according to claim 8.

10. A simulator according to claim 9 in which the simulator is a flight simulator, an air traffic control simulator, or a driving simulator.
