Abstract

A wireless communication device for motion blur detection comprising a transceiver, an optical sensor, a motion sensor, a processor and a memory. The transceiver provides wireless communication with a remote device. The optical sensor captures an image, and the motion sensor generates motion information associated with the image captured by the optical sensor. The processor controls the wireless communication by the transceiver and, further, controls the identification and storage of the motion information associated with the image. The memory portion stores the image and the associated motion information. Upon storing, the device may transmit the image and the associate motion information to the remote device via a wireless communication link, whereby the image is processed based on the associated motion information.

Claims

1. A wireless communication device with motion blur detection comprising:

a transceiver configured to provide wireless communication with a remote device;

an optical sensor configured to capture an image;

a motion sensor configured to generate motion information associated with the image captured by the optical sensor;

a processor configured to control the wireless communication by the transceiver, the processor being further configured to control the identification and storage of the motion information associated with the image; and

a memory portion configured to store the image and the associated motion information.

2. The wireless communication device of claim 1, wherein the processor incorporates the motion information into metadata associated with the image and stores the metadata in the memory portion.

3. The wireless communication device of claim 1, wherein the optical sensor is configured to capture still image or motion video.

4. The wireless communication device of claim 1, wherein the motion sensor is an accelerometer, a gyroscope, or a second optical sensor.

5. The wireless communication device of claim 1, wherein the transceiver transmits the image and the associated motion information to the remote device via a wireless communication link.

6. The wireless communication device of claim 1, wherein the motion information includes translational motion information.

7. The wireless communication device of claim 6, wherein the translational motion information includes translational motion in at least two dimensions.

8. The wireless communication device of claim 1, wherein the motion information includes rotational motion information.

9. The wireless communication device of claim 8, wherein the rotational motion information includes rotational motion in at least two directions.

10. A method of a wireless communication device for motion blur detection, the method comprising:

capturing an image using an optical sensor of the wireless communication device;

generating motion information using a motion sensor of the wireless communication device;

storing the motion information in a memory portion of the wireless communication device; and

transmitting the image and the associate motion information to a remote device via a wireless communication link, whereby the image is processed based on the associated motion information.

11. The method of claim 10, further comprising:

determining whether the motion information is available; and

retrieving the motion information upon determining that the motion information is available.

12. The method of claim 10, further comprising detecting activation at a user interface of the method, wherein capturing an image and generating motion information occurs in response to detecting the activation of the user interface.

13. The method of claim 10, further comprising incorporating the motion information into metadata associated with the image before storing the metadata in the memory portion.

14. The method of claim 10, wherein transmitting the image and the associated motion information to a remote device via a wireless communication link includes transmitting the image and associated motion information while the device is not otherwise communicating wirelessly.

15. The method of claim 10, wherein transmitting the image and the associated motion information to a remote device via a wireless communication link includes transmitting the image and associated motion information while the device otherwise communicating wirelessly.

16. The method of claim 10, wherein the motion information includes translational motion information.

17. The method of claim 16, wherein the translational motion information includes translational motion in at least two dimensions.

18. The method of claim 10, wherein the motion information includes rotational motion information.

19. The method of claim 18, wherein the rotational motion information includes rotational motion in at least two directions.
