Abstract

A camera is attached to a first vehicle and directed away from the first vehicle in order to capture images of object that are near or which approach the first vehicle, including a second vehicle configured to receive and process image data. Data representing images that are captured by the camera of the first vehicle are transmitted to a second vehicle. The image data from the first vehicle is used to provide images of the exterior of the second vehicle from the perspective of the first vehicle.

First claim

What is claimed is:

1 . An apparatus for a vehicle, the apparatus comprising:
a first radio channel coupled to the vehicle, the first radio channel configured to receive a broadcast of a beacon, the beacon advertising that captured image data is available for reception via a second radio channel; a second radio channel coupled to the vehicle, the second radio channel configured to receive captured image data; and a display device inside the vehicle and configured to display images represented by the received captured image data.

2 . The apparatus of claim 1 , wherein the captured image data represents images of objects behind the vehicle.

3 . The apparatus of claim 1 , wherein the first radio channel is a low data-rate signaling channel configured to establish a connection via said first radio channel, and wherein the second radio channel is a high data-rate communication channel configured to receive captured image data in real time, after the connection via the first radio channel is established.

4 . The apparatus of claim 1 , wherein the beacon comprises a signal having information that identifies the location and identity of a vehicle broadcasting the beacon, said vehicle that broadcasts the beacon being capable of sharing captured image data via the second radio channel.

5 . The apparatus of claim 1 , wherein the beacon provides information identifying image data sharing capabilities.

6 . The apparatus of claim 1 , further comprising a directional antenna and wherein the beacon is received from the directional antenna from a first predetermined direction.

7 . An apparatus for a vehicle, the apparatus comprising:
a camera attached to a first vehicle and directed away from the first vehicle, the camera being configured to capture images and to provide captured image data; and a first radio channel configured to broadcast a beacon, which advertises that captured image data is available for transmission from the first vehicle; and a second radio channel configured to transmit captured image data.

8 . The apparatus of claim 7 , wherein the first radio channel is a low data-rate signaling channel configured to establish a connection, and wherein the second radio channel is a high data-rate communication channel configured to transmit capture image data in real time.

9 . The apparatus of claim 7 , wherein the beacon comprises a signal having information that identifies the location of the first vehicle and the identity of the first vehicle.

10 . The apparatus of claim 7 , wherein the beacon carries information identifying image data sharing capabilities of the vehicle.

11 . The apparatus of claim 7 , further comprising a directional antenna and wherein the beacon is transmitted from the directional antenna in a first predetermined direction.

12 . A method of sharing images captured by a camera attached to a first vehicle and which captures images of objects external to said first vehicle, the method comprising:
transmitting a shared-image-available beacon signal from the first vehicle using a first radio channel; selectively transmitting captured image data using a second radio channel responsive to reception of the beacon signal via the first radio channel.

13 . The method of claim 12 , wherein the step of transmitting a shared-image-available beacon signal additionally comprises transmitting the beacon signal at a low data rate, and wherein the step of selectively transmitting captured image comprises transmitting said captured image data via a high data-rate communications channel.

14 . The method of claim 12 , wherein the step of selectively transmitting captured image is performed after a wireless connection is established between the first vehicle and a second vehicle via the first radio channel.

15 . The method of claim 14 , wherein the connection is established when the first vehicle and the second vehicle are separated from each other by a distance that is less than a predetermined threshold.

16 . The method of claim 14 , wherein the step of transmitting a shared-image-available beacon signal additionally comprises transmitting information that identifies the location of the first vehicle and the identity of the first vehicle.

17 . The method of claim 14 , wherein the steps of transmitting a shared-image-available beacon signal and selectively transmitting captured image data comprises transmitting said signal and said data using a directional antenna.

18 . A method of displaying images in a first vehicle, which are captured by a camera attached to a second vehicle, the method comprising:
receiving at the first vehicle, a shared-image-available beacon signal using a first radio channel; selectively receiving at the first vehicle, captured image data using a second radio channel, after reception of the shared-image-available beacon signal via the first radio channel.

19 . The method of claim 18 , wherein the step of receiving a shared-image-available beacon signal additionally comprises receiving the beacon signal at a low data rate, and wherein the step of selectively receiving captured image comprises receiving said captured image data via a high data-rate communications channel.

20 . The method of claim 18 , wherein the step of selectively receiving captured image is performed after a wireless connection is established between the first vehicle and a second vehicle via the first radio channel.

21 . The method of claim 20 , wherein the connection is established when the first vehicle and the second vehicle are separated from each other by a distance that is less than a predetermined threshold.

22 . The method of claim 20 , wherein the step of receiving a shared-image-available beacon signal additionally comprises receiving information that identifies the location of a second vehicle and the identity of the second vehicle.

23 . The method of claim 20 , wherein the steps of transmitting a shared-image-available beacon signal and selectively transmitting captured image data comprises transmitting said signal and said data using a directional antenna.
