Camera cell phone with integrated wireless mouse

1. An accessory for a hand-held electronics device having an integrated camera unit, comprising:

a member, sized and shaped for attachment along an outer surface of the hand-held electronics device, the member having an aperture defined therethrough, the aperture being positioned along the member such that when the member is attached to the hand-held electronics device, the aperture is positioned adjacent the camera unit of the hand-held electronics device to allow for image capture thereby;

a light element disposed within the aperture; and

a lens mounted in a stationary position within the aperture of the member to modify an optical power of the camera unit,

wherein the accessory is used as a retrofit means for providing wireless mouse functionality to the hand-held electronics device.

2. The accessory of claim 1 , wherein the member has a substantially U-shaped profile with an open end for engaging with a portion of the hand-held electronics device.

3. The accessory of claim 1 , further comprising suspending elements projecting outward from a lower portion of the member such that when the member is placed on a surface, the suspending elements elevate the member away from the surface.

4. The accessory of claim 1 further comprising an accessory battery separate from a battery of the electronics device, and an accessory charging connector configured to engage a charging connector of the hand-held electronics device such that when the accessory and the electronics device are combined, the accessory battery is charged in parallel with the battery of the electronics device via a charger of the electronic device.

5. The accessory of claim 1 further comprising a host interface for engagement with a peripheral interface of the hand-held electronics device, wherein the accessory draws power for the light element through the host interface.

6. The accessory of claim 5 further comprising first and second buttons on sides opposite the aperture, wherein a state of the first and second buttons is communicated through the host and peripheral interfaces to the hand-held electronics device, and by a wireless peripheral interface to a computer for use in manipulating a command element.

7. The accessory of claim 1 , wherein the light element is a light emitting diode or laser diode, wherein the diode emits monochromatic light having a peak wavelength that is approximately equal to a wavelength of peak sensitivity of at least one of a plurality of types of photosites of an image sensor of the integrated camera unit.

8. The accessory of claim 1 , wherein the hand-held electronics device is at least one of a cellular telephone and a device having a cellular telephone functionality.

9. The accessory of claim 1 , wherein the lens causes the camera unit to capture an unfocused image of a surface when the accessory and hand-held electronics device are placed thereon.

10. The accessory of claim 1 , further comprising software code stored in a memory within the hand-held electronics device, which when executed by the hand-held electronics device, causes the hand-held electronics device and the accessory to together function as an electronic mouse.

11. An accessory for a hand-held electronics device having an integrated camera unit, comprising:

a member for attachment along an outer surface of the hand-held electronics device, the member having an aperture defined therethrough, the aperture being positioned along the member such that when the member is attached to the hand-held electronics device, the aperture is positioned adjacent the camera unit of the hand-held electronics device to allow for image capture thereby;

a light element disposed within the aperture; and

a lens mounted in a stationary position within the aperture of the member to modify an optical power of the camera unit, wherein the accessory and the hand-held electronics device together function as an electronic mouse.

12. The accessory of claim 11 , wherein the light element is a light emitting diode or laser diode, and wherein the diode emits monochromatic light having a peak wavelength that is approximately equal to a wavelength of peak sensitivity of at least one of a plurality of types of photosites of an image sensor of the integrated camera unit.

13. The accessory of claim 11 , wherein the lens causes the camera unit to capture an unfocused image of a surface when the accessory and hand-held electronics device are placed thereon.
