Patent ID: 8270801

Claim:
A video device, comprising: a video capturing unit having a field of view, the video capturing unit to capture a video, the video comprising a plurality of images; a position sensing unit to sense a first position information of the video device; an orientation sensing unit to sense which orientation the video capturing unit faces; a timer; a wireless communication unit rotatingly communicating with a plurality of portable communication devices some of which are in the field of view, and to receive second position information of each of the portable communication devices and personal information from each of the communication portable devices; and a central processing unit (CPU) to: begin the timer when the video capturing unit starts to capture the video and clear the timer and begin the timer again when the time of the timer reaches a predetermined time; obtain the second position of the portable communication device and the personal information through the wireless communication unit, the first position information from the position sensing unit, and the orientation from the orientation sensing unit when the time of the timer reaches the predetermined time; form a coordinate system and convert the first position information and the second position information into a set of coordinates according to the coordinate system, the origin of the coordinate system being the intersection of the determined orientation and the position sensing unit; determine whether one of the portable communication devices is in the field of view according to the coordinate system and the set of coordinates of the one of the portable communication devices; determine which person of one captured image corresponds to one of the portable communication devices according to the second position information of the one of the wireless communication units if the one of the portable communication devices is in the field of view, and associate the personal information from one of the portable communication devices with the determined person of the captured image; and generate a composite image according to the relationship between each determined person of the captured image and the personal information associated with each determined person of the captured image and generate a composite video including the composite images.
