Abstract

Control methods, a digital camera and a digital camera user interface that respond to arm, hand and/or finger gestures. The digital camera recognizes the arm, hand and/or finger gestures as inputs to its user interface and responds to implement predetermined tasks or operations.

Claims

1. A digital camera comprising:

imaging optics;

an image sensor for receiving images transmitted by the imaging optics; and

a processor coupled to the image sensor that implements a user interface comprising a motion detection algorithm that recognizes predetermined movements of a user and performs predetermined tasks corresponding to the predetermined movements.

2. The digital camera recited in claim 1 wherein the motion detection algorithm detects left and right motion in the images received from the image sensor.

3. The digital camera recited in claim 1 wherein the motion detection algorithm detects up and down motion in the images received from the image sensor.

4. The digital camera recited in claim 2 wherein prerecorded images on the camera are scrolled in response to the left and right detected motion.

5. The digital camera recited in claim 2 wherein a cursor/highlight is moved on the display in response to the detected motion.

6. The digital camera recited in claim 1 wherein the processor further comprises a training algorithm for training the motion detection algorithm to identify the predetermined movements of the user.

7. A system comprising:

a digital camera comprising a user interface comprising a motion detection algorithm that recognizes predetermined movements of a user and performs predetermined tasks corresponding to the predetermined movements;

an external display device, and

an electrical interface that allows prerecorded images contained in the camera to be displayed on the external display device; and

wherein motion detected by the motion detection algorithm of the camera causes predetermined tasks to be performed by the camera, and changes information displayed on the external display device.

8. The system recited in claim 7 wherein the interface comprises a motion detection algorithm that detects left and right motion in the images.

9. The system recited in claim 8 wherein the left and right motion of the images is reinterpreted by the motion detection algorithm as left and right, respectively.

10. The system recited in claim 7 wherein the interface comprises a motion detection algorithm that detects up and down motion in the images.

11. The system recited in claim 10 wherein prerecorded images on the camera are scrolled in response to the detected up and down motion.

12. The system recited in claim 7 wherein a cursor/highlight is moved on the display in response to the detected motion.

13. The system recited in claim 7 wherein the motion detection algorithm further comprises a training algorithm for training the motion detection algorithm to identify the predetermined movements of the user.

14. A control method comprising the steps of:

providing an external display device;

coupling an electrical interface to the external display device that allows prerecorded images to be displayed on external display device;

coupling a digital camera to the external display device by way of the electrical interface, which digital camera comprises an electrical interface comprising a motion detection algorithm that recognizes predetermined movements of a user and performs predetermined tasks corresponding to the predetermined movements;

performing one or more predetermined movements that cause predetermined tasks to be performed by the camera; and

detecting the one or more predetermined movements using the motion detection algorithm of the camera to cause one or more of the predetermined tasks to be performed by the camera, and change information displayed on the external display device.

15. The method recited in claim 14 wherein the detecting step further comprises the steps of detecting left and right motion in the images processed by the motion detection algorithm and interpreting the left and right motion as left and right, respectively.

16. The method recited in claim 14 wherein the detecting step further comprises the steps of detecting up and down motion in the images processed by the motion detection algorithm and interpreting the up and down motion as up and down, respectively.

17. The method recited in claim 14 further comprising the step of scrolling through the predetermined images on the camera in response to the detected movements.

18. The method recited in claim 14 further comprising the step of moving a cursor/highlight on the display in response to the detected movements.

19. The method recited in claim 14 further comprising the step of training the motion detection algorithm to identify the predetermined movements of the user.
