Abstract

A camera flash device, method and computer program for communicating between a primary camera flash device and other camera flash devices comprising: detecting orientation and position of the camera flash device and range of a primary subject in focus on the camera flash device; locating other networkable camera flash devices for communication; receiving subject data for a real time image of a subject from one or more of the located networkable camera flash devices; determining from subject data which networkable camera flash devices are pointing at the primary subject; determining two or more camera flash devices for use in a picture; and synchronizing determined two or more camera flash devices for flash operation when one or more of the camera flash devices takes a picture of the primary subject.

First claim

What is claimed is:

1. A camera flash device comprising:
detectors for detecting the orientation and position of the camera flash device and the distance from a subject in focus on the camera flash device;
a camera network identifier for locating networkable camera flash devices for communication across a network, wherein the camera network identifier is configured to locate the networkable camera flash devices in response to a picture button on the camera flash device being partially depressed, and wherein the camera flash device is configured to set the camera flash device as a master camera flash device in response to the picture button being partially depressed;
a camera network database for receiving subject data for real time image subjects from one or more of the networkable camera flash devices;
a primary subject camera identifier for determining from subject data which networkable camera flash devices are focused on the subject;
a camera flash option engine for determining two or more subject camera flash devices for use in a picture; and
a camera flash synchronization engine for synchronizing said two or more subject camera flash devices for flash operation when one or more of the subject camera flash devices takes a picture of the subject.

2. The camera flash device of claim 1 , wherein the camera flash option engine is for determining camera flash setting options for the networkable camera flash devices.

3. The camera flash device of claim 1 , wherein the camera flash option engine is further for selecting an optimum camera flash setting option.

4. The camera flash device of claim 1 , wherein the camera flash device requests one or more of the networkable camera flash devices to take one or more pictures of the subject.

5. The camera flash device of claim 1 , wherein the camera flash device receives camera capability data from the networkable camera flash devices.

6. The camera flash device of claim 1 , wherein the camera flash device determines a range of camera conditions from the networkable camera flash devices.

7. The camera flash device of claim 6 , wherein the camera flash device determines a range of camera settings suitable for the range of conditions and communicates the camera settings to the networkable camera flash devices.

8. The camera flash device of claim 6 , wherein the range of camera conditions from the networkable camera flash devices comprises a respective amount of background light on the primary subject and a respective amount of foreground light on the primary subject.

9. The camera flash device of claim 1 , wherein camera settings are optimized according to an individual camera flash device capability.

10. The camera flash device of claim 1 , wherein the network is a peer-to-peer network.

11. The camera flash device of claim 1 , wherein the networkable camera flash devices exchange the one or more pictures.

12. The camera flash device of claim 1 , wherein the camera network identifier for locating networkable camera flash devices for communication across a network is configured to locate networkable camera flash devices in a restricted part of the possible network area, wherein the restricted part of the possible network area comprises an area of the primary subject.

13. A method for communicating between a primary camera flash device and other camera flash devices comprising:
detecting orientation and position of the primary camera flash device and distance from a subject in focus on the primary camera flash device;
locating other networkable camera flash devices for communication across a network in response to a picture button on the primary camera flash device being partially depressed, wherein the primary camera flash device is configured to set the primary camera flash device as a master camera flash device in response to the picture button being partially depressed;
receiving subject data for a real time image of the subject from one or more of the networkable camera flash devices;
determining from the subject data which networkable camera flash devices are pointing at the subject;
determining two or more camera flash devices for use in a picture; and
synchronizing two or more of the camera flash devices for flash operation when one or more of the camera flash devices takes a picture of the subject.

14. The method of claim 13 , further comprising:
determining camera flash setting options for primary camera flash device and the networkable camera flash devices.

15. The method of claim 13 , further comprising:
selecting an optimum camera flash setting.

16. The method of claim 13 , further comprising:
requesting one or more of the networkable camera flash devices to take one or more pictures of the subject.

17. The method of claim 13 , further comprising:
receiving camera capability data from the networkable camera flash devices.

18. The method of claim 13 , further comprising:
determining a range of camera conditions from the networkable camera flash devices.

19. The method of claim 18 , further comprising:
determining a range of camera settings most suitable for the range of conditions and communicating the camera settings to the networkable camera flash devices.

20. A computer program product for communicating between a primary camera flash device and other camera flash devices, the computer program product comprising:
one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
program instructions to detect orientation and position of the primary camera flash device and distance from a subject in focus on the primary camera flash device;
program instructions to locate networkable camera flash devices for communication across a network in response to a picture button on the primary camera flash device being partially depressed, wherein the primary camera flash device is configured to set the primary camera flash device as a master camera flash device in response to the picture button being partially depressed;
program instructions to receive subject data for a real time image of a subject from one or more of the networkable camera flash devices;
program instructions to determine from the subject data which networkable camera flash devices are pointing at the subject;
program instructions to determine two or more camera flash devices for use in a picture; and
program instructions to synchronize the two or more camera flash devices for flash operation when one or more of the networkable camera flash devices takes a picture of the subject.
