Abstract

One or more display elements of an apparatus provide light representative of distant objects and near objects and at least one optical element of the apparatus is responsive to the light representative of the near objects, for providing video images of the near objects at one or more near focal lengths, and is responsive to the light representative of distant objects, for providing video images of the distant objects at one or more far focal length and positioned for viewing at an elevation above the video images of the near objects.

Claims

1. Apparatus, comprising:

at least one processor and at least one memory including a computer program, the at least one memory and the computer program configured to, with the at least one processor, cause the apparatus to process at least one video signal comprising images of distant objects and images of near objects wherein the images of the near objects are plenoptic images optimized for spatial resolution at the expense of angular resolution and the images of the distant objects are plenoptic images optimized for angular resolution at the expense of spatial resolution, the apparatus further comprising;

at least one display element, responsive to the at least one processed video signal, for providing light representative of the distant objects and for providing light representative of the near objects; and

at least one optical element, responsive to the light representative of the near objects from the at least one display element, for providing video images of the near objects at one or more near focal lengths, and responsive to the light representative of distant objects from the at least one display element, for providing video images of the distant objects at one or more far focal lengths and positioned for viewing above the video images of the near objects.

2. The apparatus of claim 1, wherein the at least one memory and the computer program are configured to, with the at least one processor, cause the apparatus to retrieve the video signal from the at least one memory.

3. The apparatus of claim 2, wherein the at least one memory and the computer program are configured to, with the at least one processor, receive a streaming video signal from a network over a wired or wireless connection to the apparatus and cause the apparatus to process said received streaming video signal for providing said processed streaming video signal to said at least one display element for said providing light representative of distant objects and for providing light representative of near objects.

4. The apparatus of claim 1, further comprising a receptacle for receiving a portable memory device insertable into the receptacle, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to retrieve the video signal from the portable memory device after insertion of the portable memory device in the receptacle.

5. The apparatus of claim 1, wherein the images of at least the distant objects are quasi panoramic or wide field-of-view images.

6. The apparatus of claim 1, wherein the images of the distant objects are quasi-panoramic or wide field-of-view images and the images of the near objects are not quasi-panoramic or wide field-of-view images.

7. The apparatus of claim 1, further comprising:

at least one light capturing element, responsive to light reflected from the distant objects, for providing captured light reflected from the distant objects, and responsive to light reflected from the near objects, for providing captured light reflected from the near objects, wherein the captured light reflected from the far objects is reflected from the distant objects positioned at one or more positions above the near objects and the captured light reflected from the near objects is reflected from the near objects positioned at one or more positions below the far objects;

at least one light sensor, responsive to the captured light reflected from the distant objects and to the captured light reflected from the near objects, for providing at least one sensed signal; and

at least one processor, responsive to the at least one sensed signal, for providing the at least one video signal comprising the images of the distant objects and the near objects.

8. The apparatus of claim 7, wherein the at least one memory and the computer program are configured to, with the at least one processor, cause the apparatus to store the video signal from the at least one processor in the at least one memory.

9. The apparatus of claim 7, further comprising a receptacle for receiving a portable memory device insertable into the receptacle, wherein the at least one memory and the computer program are configured to, with the at least one processor, cause the apparatus to retrieve the video signal from the portable memory device either automatically or upon user command after insertion of the portable memory device in the receptacle.

10. The apparatus of claim 7, wherein the images of at least the distant objects are quasi-panoramic or wide field-of-view images.

11. The apparatus of claim 7, wherein the images of the distant objects are quasi-panoramic or wide field-of-view images and the images of the near objects are not quasi-panoramic or wide field-of-view images.

12. The apparatus of claim 7, wherein the video signal is a streaming video signal and wherein the at least one memory and the computer program are configured to, with the at least one processor, send the streaming video signal to a network over a wired or wireless connection from the apparatus.
