Abstract

Described herein are methods and devices that employ wireless network to control the lighting of a target image scene or subject. As described, connected environments enable control of lighting devices within the environment through the use of a network. Some embodiments of the imaging devices described herein may employ the network to control lighting devices for the purpose of illuminating a target scene or subject. Certain embodiments may employ data regarding camera location, subject location, light bulb location, and the parameters of each light bulb in a room to calculate desired lighting parameters for capturing an image of the subject, and may further be able to wirelessly adjust the light bulb parameters to match the calculated parameters.

Claims

1. An image capture device comprising:

an image sensor configured to capture an image of a target subject;

a networking module configured to detect at least one illumination device proximate to the target subject, wherein the at least one illumination device is part of a networked environment;

a calculation module configured to calculate optimal lighting settings; and

a control module configured to adjust the at least one illumination device according to the optimal lighting settings.

2. The image capture device of claim 1, wherein at least one parameter is associated with the at least one illumination device.

3. The image capture device of claim 2, wherein the at least one parameter is one of brightness, type of light bulb, or location of the at least one illumination device.

4. The image capture device of claim 1, wherein the networking module comprises a wireless network connection to a proximity-based peer-to-peer network.

5. The image capture device of claim 1, wherein the networked environment is a connected home.

6. A method of image capture comprising:

receiving preview image data of a target subject on an image capture device;

receiving data representing at least one parameter of at least one light source in a local environment of the target subject;

calculating optimal lighting parameters for the target subject;

adjusting the at least one parameter of the at least one light source according to the optimal lighting parameters; and

capturing the image.

7. The method of claim 6, wherein calculating optimal lighting parameters comprises:

presenting the at least one parameter of the at least one light source to a user on a user interface of the image capture device; and

receiving user input regarding a setting for the at least one parameter.

8. The method of claim 6, wherein calculating optimal lighting parameters is carried out automatically by the image capture device.

9. The method of claim 6, wherein calculating optimal lighting parameters comprises determining a location of the target subject.

10. The method of claim 9, wherein determining a location of the target subject comprises using an auto-focus lens position of the image capture device to calculate an approximate distance of the target subject from the image capture device.

11. The method of claim 9, wherein determining a location of the target subject comprises updating the location as the target subject moves.

12. The method of claim 6, wherein calculating optimal lighting parameters comprises determining a location of the at least one light source.

13. The method of claim 12, wherein calculating optimal lighting parameters further comprises comparing the location of the at least one light source to a location of the target subject.

14. The method of claim 6, wherein adjusting the at least one parameter of the at least one light source is carried out via wireless communication over the network.

15. The method of claim 14, wherein the wireless communication is between the image capture device and the at least one light source.

16. The method of claim 14, wherein the wireless communication is between the image capture device and a control module of a connected home, wherein the control module communicates with the at least one light source.
