Abstract:
1. A video device comprising: a first video camera arranged m record a first video image of a first field of view and is operable to output a first stream of video dam based on the first video image; a second video camera arranged to record a second video image of a second field of view and is operable to output a second stream of video data based on the second video image; a view synthesizer operable to perform selectively one of generating a stitched video image stream, generating a first picture-in-picture video image stream and generating a second picture-in-picture video image stream, the generating of a stitched video image stream comprises stitching an adjusted first video image stream and an adjusted second video image stream, the adjusted first video image stream being based, on the first video image stream, the adjusted second video image stream being based on the second video image stream, the stitched video image stream having a third field of view, the generating of a first picture-in- picture video image stream comprises replacing a first portion of the adjusted first video image stream corresponding to a first portion of an adjusted first video image with a second portion of the adjusted second video image stream corresponding to a second portion of an adjusted second video image, the generating of a second picture-in-picture video image stream comprises replacing a third portion of the adjusted second video image stream corresponding to a third portion of the adjusted second video image with a fourth portion of the adjusted first video image stream corresponding to a fourth portion of the adjusted first video image; a controller operable to instruct said view synthesizer to output a raw video signal as one of the adjusted first video image stream, the adjusted second video image stream, the stitched video image stream, the first picture-in-picture video image stream and the second picture-in-picture video image stream; and an encoder operable to encode the raw video signal into an encoded signal.
