Projector as light source for an image capturing device

1. A method comprising:

illuminating a work space using a lens of a projector;

defocusing the lens;

after defocusing the lens, capturing an image of the work space; and

after capturing the image, refocusing the lens.

2. The method of claim 1 wherein defocusing the lens comprises:

receiving, using a processor, a first signal that an image capturing device is about to capture an image;

sending, using the processor, a second signal to a motor coupled to the lens, the second signal instructing the motor to rotate the lens.

3. The method of claim 1 wherein refocusing the lens comprises:

sending, using a processor, a signal to a motor coupled to the lens, the signal instructing the motor to rotate the lens.

4. The method of claim 3 wherein the signal comprises a signal to return the lens to the position of the lens during said illuminating a work space using a lens of a projector.

5. The method of claim 1 further comprising, receiving, using a processor, a signal from a user input device to capture an image of the work space.

6. The method of claim 1 further comprising displaying the captured image.

7. A device comprising:

a projector comprising a lens;

an image capturing device;

a display; and

a processor coupled to the projector, the image capturing device, and the display, the processor comprising instructions for:

illuminating a work space using the lens;

defocusing the lens;

after defocusing the lens, capturing an image of the work space; and

displaying the captured image on the display; and

refocusing the lens after capturing the image.

8. The device of claim 7 further comprising a motor coupled to the lens, wherein the processor further comprises instructions for:

receiving a first signal that the image capturing device is about to capture an image;

sending a second signal to the motor instructing the motor to rotate the lens.

9. The device of claim 7 further comprising a user input device, wherein the processor further comprises instructions for receiving a signal from the user input device to capture an image of the work space.

10. A non-transitory computer readable medium encoded with instructions executable by a processor to:

illuminate a work space using a lens;

rotate the lens to defocus the lens;

after rotating the lens, capture an image of the work space with a camera; and

after capturing an image of the work space with a camera, rotate the lens to refocus the lens.

11. The non-transitory computer readable medium of claim 10 , wherein the instructions are further executable by the processor to:

receive a signal that the camera is about to capture an image;

rotate the lens using a motor coupled to the lens.

12. The non-transitory computer readable medium of claim 10 , wherein the instructions are further executable by the processor to:

display the captured image with a display device.
