Abstract

A device may include a camera to capture an image; a sensor to measure, when the camera captures the image, information indicative of an angular displacement, about a line of sight of the camera, of an orientation of the device away from a reference orientation of the device; storage to store the measured information for rotating the image relative to a frame of the image based on the angular displacement.

Claims

1. A device comprising:

a camera to capture an image;

a sensor to measure information indicative of an angular displacement, about a line of sight of the camera, of an orientation of the camera away from a reference orientation of the camera when the camera captures the image; and

storage to store the measured information.

2. The device of claim 1, further comprising

a processor to rotate the image relative to the frame of the image based on the angular displacement, and wherein the storage stores the rotated image.

3. The device of claim 1, further comprising

a communication interface for transferring the measured information and the image to a computer for rotating the image relative to the frame of the image based on the angular displacement.

4. The device of claim 1, further comprising

an indicator to indicate when the angular displacement is zero.

5. The device of claim 1, further comprising

a processor to capture automatically the image when the angular displacement is zero.

6. A method comprising:

capturing an image in a camera;

when capturing the image, measuring information indicative of an angular displacement, about a line of sight of the camera, of an orientation of the camera away from a reference orientation of the camera;

storing the measured information for rotating the image relative to a frame of the image based on the angular displacement;

rotating the image relative to the frame of the image based on the angular displacement; and

storing the rotated image.

7. The method of claim 6, further comprising

transferring the measured information and the image to a personal computer for rotating the image relative to the frame of the image based on the angular displacement.

8. The method of claim 6, further comprising

indicating when the angular displacement is zero.

9. The method of claim 6, further comprising

automatically capturing the image when the angular displacement is zero.

10. A computer-readable medium comprising a data structure, the data structure comprising

a first data field to store an image captured by a camera;

and

a second data field to store information measured by a sensor when the camera captured the image, the measured information indicative of an angular displacement of an orientation of the camera away from a reference orientation of the camera.

11. A computer-readable medium comprising instructions to operate a processor for performing a method, the method comprising:

receiving measured information for rotating an image relative to a frame of the image, wherein the image was captured by a camera, wherein the measured information is indicative of an angular displacement, about a line of sight of the camera, of an orientation of the camera away from a reference orientation of the camera, and wherein the information was measured when capturing the image;

rotating the image relative to the frame of the image based on the angular displacement; and

storing or displaying the rotated image.

12. A device comprising:

means for capturing an image in a camera;

means for measuring, when capturing the image, information indicative of an angular displacement of an orientation of the camera away from a reference orientation of the camera; and

means for storing the measured information for rotating the image relative to a frame of the image based on the angular displacement.

13. The method of claim 12, further comprising

means for rotating the image relative to the frame of the image based on the angular displacement, and wherein the means for storing stores the rotated image.

14. The method of claim 12, further comprising

means for transferring the stored measured information and the image to a personal computer for rotating the image relative to the frame of the image based on the angular displacement.

15. The method of claim 12, further comprising

means for indicating when the angular displacement is zero.

16. The method of claim 15, further comprising

means for automatically capturing the image when the angular displacement is zero.
