Abstract

A hand-held accessory for a camera-equipped device comprises a short-range transceiver to transmit signals to and receive signals from the camera-equipped device. A controller and a display are operatively connected to the short-range transceiver. The controller generates control signals responsive to user input, and conveys the control signals to the short-range transceiver for transmission to the camera-equipped device. The control signals control the camera functionality on the camera-equipped device. Images captured by the camera-equipped device may be displayed on the accessory display.

Claims

1. A hand-held accessory for a camera-equipped cellular communication device comprising:

a short-range transceiver to transmit signals to and receive signals from the camera-equipped cellular communication device having a flash;

a light sensor configured to measure light emitted by the flash device;

a controller operatively coupled to the short-range transceiver and configured to generate control signals to remotely control the camera-equipped device to;

activate the flash to emit light at a first predetermined luminosity to be measured by the light sensor;

control the camera-equipped device to adjust the intensity of the flash to a second luminosity responsive to the amount of light measured by the light sensor; and

activate the flash to emit light at a second luminosity to capture an image, the second luminosity being based on the amount of measured light; and

a display operatively coupled to the short-range transceiver to display the captured image.

2. The accessory of claim 1 wherein the short-range transceiver communicates with a corresponding short-range transceiver associated with the camera-equipped device using a short-range wireless interface.

3. The accessory of claim 1 further comprising a user interface operatively coupled to the controller to accept user input.

4. The accessory of claim 3 wherein the controller generates the control signals responsive to the user input.

5. The accessory of claim 3 wherein the user interface comprises a keypad.

6. The accessory of claim 3 wherein the user interface comprises a touch-sensitive screen.

7. The accessory of claim 1 wherein the control signals comprise first and second control signals that are generated responsive to first and second user inputs, respectively.

8. The accessory of claim 7 wherein the first and second control signals control the camera-equipped device to send the captured image to the display at first and second resolutions, respectively.

9. The accessory of claim 8 wherein the first resolution is lower than the second resolution.

10. The accessory of claim 1 wherein the control signals further remotely control a zoom function on the camera-equipped device.

11. The accessory of claim 1 wherein the control signals further remotely control a focus adjustment on the camera-equipped device.

12. The accessory of claim 1 wherein the control signals further remotely enable and disable a flash on the camera-equipped device.

13. The accessory of claim 1 wherein the controller digitally alters the captured image.

14. The accessory of claim 1 wherein the display comprises a LCD.

15. The accessory of claim 14 wherein the display is operative to display the captured images at a plurality of resolutions.

16. A method of remotely controlling a camera-equipped cellular communication device using a hand-held accessory comprising:

generating control signals to;

remotely activate a flash device associated with a camera-equipped cellular communication device to emit light at a first predetermined luminosity to be measured by a light sensor at a hand-held accessory;

remotely control the camera-equipped device to adjust the intensity of the flash device to a second luminosity responsive to the amount of measured light; and

remotely activate the flash device to emit light at the second luminosity to capture an image;

transmitting the control signals to the camera-equipped device using a short-range transceiver;

receiving signals from the camera-equipped device using the short-range transceiver; and

displaying the captured image on a display of the hand-held accessory.

17. The method of claim 16 wherein generating control signals comprises generating a first control signal responsive to a first user input, and a second control signal responsive to a second user input.

18. The method of claim 17 further comprising controlling the camera-equipped device to send the captured image to the display at first and second resolutions responsive to the first and second control signals, respectively.

19. The method of claim 18 wherein the first resolution is lower than the second resolution.

20. The method of claim 16 further comprising digitally altering the captured image for display.

21. The method of claim 16 further comprising generating the control signals responsive to user input.

22. The method of claim 16 further comprising controlling a zoom function of the camera-equipped device via the control signals.

23. The method of claim 16 further comprising controlling a focus adjustment of the camera-equipped device via the control signals.

24. The method of claim 16 further comprising enabling and disabling a the flash device associated with the camera-equipped device via the control signals.

25. The method of claim 16 further comprising displaying the captured image at a plurality of resolutions.

26. The method of claim 16 wherein the short-range transceiver communicates with the camera-equipped device using a short-range wireless interface.
