Attachment for a personal communication device

Abstract

A personal communication device, such as a smartphone handset comprises a main body incorporating a camera having a lens. An attachment for the personal communication device is detachably mountable to the main body by means of a cover. The attachment also comprises an optical device arranged to reflect light into the lens from a panoramic field of view. The optical device includes a convex mirror, which preferably reflects light from a 360° field of view into the camera. Such an arrangement enables the user to completely capture an image of his surroundings, so that the image is an objective record of a moment in time as experienced by the user. The invention is more portable and versatile than previous arrangements.

I claim: 
     
         1 . An attachment for a personal communication device comprising a main body incorporating a camera, the attachment comprising an optical device arranged to be detachably mountable to the main body in a fixed relationship with respect to the lens of the camera, the optical device being arranged to reflect light into the lens from a panoramic field of view. 
     
     
         2 . An attachment as claimed in  claim 1 , in which the optical device is arranged to reflect light from a panoramic field of view of at least 180°. 
     
     
         3 . An attachment as claimed in  claim 1 , in which the optical device is arranged to reflect light from a panoramic field of view of substantially 360°. 
     
     
         4 . An attachment as claimed in any one of  claim 1 , in which the optical device comprises a light capturing device in a housing, and the optical device is adjustable between an operating position and a stored position by relative movement between the light capturing device and a portion of the housing. 
     
     
         5 . An attachment as claimed in  claim 4 , further comprising an adjusting mechanism arranged to be operable by the user in order to control the position of one of the light capturing device and the portion of the housing between the operating and stored positions. 
     
     
         6 . An attachment as claimed in  claim 4 , in which the light capturing device has a first optical axis and the lens of the camera has a second optical axis, and the fixed relationship between the optical device and the main body is a such that the first optical axis is transverse to the second optical axis. 
     
     
         7 . An attachment as claimed in  claim 6 , in which the optical device further comprises a mirror arrangement arranged to reflect light from a direction substantially parallel to the first optical axis to a direction substantially parallel to the second optical axis. 
     
     
         8 . An attachment as claimed in any one of  claim 4 , in which the light capturing device comprises a convex mirror. 
     
     
         9 . An attachment as claimed in  claim 7 , in which the light capturing device and the mirror arrangement are located in a predetermined position and orientation with respect to each other in both the stored and operating positions. 
     
     
         10 . An attachment as claimed in  claim 1 , further comprising a cover, a first portion of which is arranged to house at least part of the optical device and a second portion of which is detachably mountable to the main body of the personal communication device. 
     
     
         11 . An attachment as claimed in  claim 10 , in which the second portion of the cover is resilient, so that it is attachable to the main body by being stretched over it. 
     
     
         12 . An attachment as claimed in  claim 10 , in which the second portion of the cover is detachably mountable to the main body by means of fasteners. 
     
     
         13 . An attachment as claimed in  claim 10 , in which the second portion of the cover is detachably mountable to the main body by means of a snap-fit or sliding fit arrangement. 
     
     
         14 . A combination of a personal communication device having a main body incorporating a camera, with an attachment; the attachment comprising an optical device arranged to be detachably mountable to the main body in a fixed relationship with respect to a lens of the camera, the optical device being arranged to reflect light into the lens of the camera from a panoramic field of view. 
     
     
         15 . A combination of a personal communication device and an attachment as claimed in  claim 14 , in which the person communication device is one of: a mobile phone; a smartphone; a personal digital assistant; a portable personal computer; or a handheld games console. 
     
     
         16 . A method of recording a panoramic image of a scene, comprising the steps of: attaching an optical device to a personal communication device having a camera such that the optical device has a fixed relationship with respect to a lens of the camera, the optical device being arranged to reflect light into the lens of the camera from a panoramic field of view; and
 sensing and recording an image of the panoramic field of view by means of the camera.
