Abstract

A headset system connectable to a video source for receiving a video signal through a wired or wireless communication link comprises a head mounted device, a user interface and a base station. The head mounted device displays a video image to the user via an integrated video display and also comprises an integrated data image processor and optical lenses positioned in front the video display. The data image processor effects high speed real time modification of an image frame of the video signal. The video display is in communication with the data image processor for displaying processed images from the digital image processor. The user interface allows for building a user profile and storing the user profile in the memory of the digital image processor. The base station comprises an input interface connectable to the communication link, and an output interface for forwarding the communication signal to the video display.

Claims (24)

1. An integrated field-configurable headset system connectable to a video source including at least one camera and/or a computer for receiving a video signal through a wired or wireless communication link, the headset system comprising:

a head mounted device to be worn by a user for displaying a video image to the user, the head mounted device comprising:

a data image processor integrated within the head mounted device for effecting high speed real time modification of image frame of the video signal, a 3D stereoscopic decoder implemented into the data image processor for generating left and right image flows and first and second digital image processors implemented into the data image processor for respectively editing the first and second image flows;

a compact multiple screen display apparatus integrated into the head mounted device and defining a video display comprising a right micro-display and a left micro-display in communication with the data image processor for displaying augmented reality processed images from the data image processor each of the pair of digital processors being in communication with a respective one of the right and left micro-displays in order to effect high speed real time modifications of image frames of the video signal prior to displaying via the micro-displays; and

optical elements integrated in the head mounted device, the optical elements are of the kind to provide a wide field of view to improve immersion of the viewing experience to be as realistic as possible; and

a base station comprising:

a processor which comprises data storage capabilities;

a user interface for providing the user to select from amongst a set of pre-configured parameters displayed by the video display for building a user profile and storing the user profile in the processor;

an input interface connectable to the communication link; and

an output interface for forwarding the communication signal to the video display,

wherein the data image processor provides for real-time processing of the video signal according to;

(i) the stored user profile thereby compensating for an aberration in the eye of the user and the distance between the eyes of the user and the position of the video display;

(ii) both the stored user profile and a device parameter thereby compensating for the fish eye effect generated by the optical elements that provide the wide field of view;

(iii) a device parameter for compensating for an aberration of the video display, a distortion of the micro-displays and an aberration of the video signal, wherein the video signal is form of a red component, a green component and a blue component, wherein different wavelengths of the red, green and blue components lead to different aberrations of the eyes of a user, of components of the video display, and of perceptions of the user, the data image processor separately processes the red component, the blue component and the green component to compensate for the different aberrations,

thereby providing for the data image processor to compensate at the level of the head mounted device for distortions and/or aberations due to the eyes of the user, the optical elements, the video display, and the video signal while also accounting for the user profile prior to the augmented reality video image to the user.

2. A headset system according to claim 1 , wherein the user interface is integrated to the head mounted device.

3. A headset system according to claim 1 , wherein the base station is integrated to the head mounted device.

4. A headset system according to claim 1 , wherein the video signal comprises a left component and a right component, the data image processor provides for separately processing the left component and the right component.

5. A headset system according to claim 4 , wherein the data image processor processes the left component according to a parameter of a left eye of the user, and processes the right component according to a parameter of a right eye of the user.

6. A headset system according to claim 4 , wherein the data image processor processes the left component according to a parameter of a left component of the video display system; and processes the right component according to a parameter of a right component of the video display system.

7. A headset system according to claim 1 , wherein the data image processor provides for separately editing the first and second image flows according to aberrations of a left eye and of a right eye of the user and according to aberrations of a left display and of a right display of the video display system.

8. A headset system according to claim 1 , wherein the data image processor provides for dividing each image of the video signal into image blocks of an image matrix, and for defining a conversion matrix sized to match the image matrix, the conversion matrix comprising conversion blocks sized to match the blocks of the image matrix, wherein digitally processing the video signal comprises compensating each image block using a corresponding conversion block, wherein the conversion is selected from the group consisting of: a color conversion, generating a bitmap representation of the image, or to a transformation from a time domain to a frequency domain or any combination thereof.

9. A headset system according to claim 1 , wherein the data image processor provides for defining a pixel-wise conversion matrix, wherein digitally processing the video signal comprises compensating each pixel of the video signal with a pixel of the conversion matrix, wherein the conversion is selected from the group consisting of: a color conversion, generating a bitmap representation of the image, or to a transformation from a time domain to a frequency domain or any combination thereof.

10. A headset system according to claim 1 , wherein the video display merges video signals from a plurality of video source.
