20100004020 | MOBILE TERMINAL AND COMPOSITE PHOTOGRAPHING METHOD USING MULTIPLE MOBILE TERMINALS - A mobile terminal and composite photographing method using multiple mobile terminals are provided. The composite photographing method uses multiple mobile terminals. A master mobile terminal composes an incomplete composite photograph, generates a participant list of slave mobile terminals, and sends the incomplete composite photograph and participant list to a first slave mobile terminal in the participant list. The first slave mobile terminal receives the incomplete composite photograph and participant list, further composes the received composite photograph, determines whether the composed composite photograph is complete, sends, when the composed composite photograph is incomplete, the composed composite photograph to a second slave mobile terminal in the participant list, and sends, when the composed composite photograph is complete, the composed composite photograph to all mobile terminals having participated in composite photographing. Hence, several users at distinct locations can jointly produce a composite photograph. | 01-07-2010 |
