Abstract

A video module including a video sensor having a sensor video signal output terminal, a timing signal terminal, and an image field of pixel elements responsive to incident light to generate sensor video signals; a processor having a sensor video signal input terminal coupled to the output terminal, a host signal input terminal for accepting a host signal, a timing signal terminal, video pixel signal combining means responsive to the sensor video signal and the host signals simultaneously to develop display video signals where each of the pixel elements is individually manipulated and controlled, and a display video signal output terminal for outputting the display video signals; a video display having a thin screen disposed along an axis passing through the center of and perpendicular to the image field and facing oppositely from the image field, a display video signal input terminal, and a timing signal terminal, wherein the video signals generate video images on the screen; and a timer for providing timing signals.

Claims

1. Video module means comprising:

video sensor means having an image field of pixel elements responsive to incident light to generate sensor video signals, a sensor video signal output terminal, and a timing signal terminal;

processor means having a sensor video signal input terminal coupled to said output terminal, a host signal input terminal for accepting a host signal, a timing signal terminal, video pixel signal combining means responsive to said sensor video signal and said host signals simultaneously to develop display video signals where each of said pixel elements is individually manipulated and controlled, and a display video signal output terminal for outputting said display video signals;

video display means having thin screen means disposed substantially on an axis in the center of and perpendicular to said image field and facing oppositely from said image field, a display video signal input terminal, and a timing signal terminal, wherein said video display means receives display video signals for said screen means to display video images; and

timer means having a timing signal terminal for providing timing signals.

2. Video module means as recited in claim 1 wherein said video pixel signal combining means is:

for SUMming said host signals and a function of said sensor video signals, to develop said display video signals.

3. Video module means as recited in claim 1 and further comprising mounting means for positioning said module means so that said optical axis is co-axial with a line of sight;

and wherein said sensor means and display means each includes a respective focussing means, the display focussing means being focusable so that displayed images are focussed onto virtual images which, to an observer viewing along the line of sight toward said screen means, appear the same size that images sensed by said sensor means would appear if seen by the observer from the same viewpoint without said module means.

4. Video module means as recited in claim 3 and wherein virtual images appear to be in a virtual image plane located at the same distance as the sensor focussing means focal plane from the observer.

5. Video module means as recited in claim 1 wherein said combining means comprises:

physical image control means including sensor video signal buffer means;

simulation video signal buffer means; and

summation circuit means, wherein said host signals include simulation video signals, and sensor control signals which control said combining means to SUM said simulation video signals and said sensor video signals to develop said display video signals.

6. Video module means as recited in claim 5 wherein

said host signals further include display mode program control signals;

said physical image control means further includes sensor control signal buffer means for applying said sensor control signals; and

said combining means further comprises display mode program control means responsive to said display mode program control signals for configuring the operational mode and resolution of said module.

7. Video module means as recited in claim 5 wherein video input signals are SUMmed in a transparent overlay to develop said display video signals.

8. Video module means as recited in claim 5 and further comprising host means for providing said host signals.

9. Video module means as recited in claim 8 and further comprising means for wirelessly communicating said sensor and host signals between said module means and said host means.

10. Video module means as recited in claim 8 wherein sensor video signals are processed by said host means to provide said simulation video signals.

11. Video module means as recited in claim 8 wherein said host means includes pattern recognition means for inspecting said sensor video signals to recognize features that may be imaged from a physical environment and, in response, to develop said display video signals.

12. Video module means as recited in claim 8 and further comprising second module means and binocular mounting means for displaying views in three dimensions.

13. Video module means as recited in claim 8 wherein said module means comprises tracking means for determining the position of said module relative to its physical environment.

14. Video module means as recited in claim 13 wherein said host means can track positions of said module in said physical environment.
