20080298690 | Digital Photo Content Processing System and Method and Apparatus for Transmitting/Receiving Digital Photo Contents Thereof - A system for processing digital photo contents in a digital camera is disclosed. The system includes a content transmitting unit, and a content receiving unit. The content transmitting unit creates an image by photographing objects in a photographing area, requests supplementary information to at least one of persons in the photographing area, receives personal IDs from at least one of target persons, composes digital photo contents using the created image and the personal ID and stores the composed digital photo contents, and transmits after classifying the stored digital photo content by the received personal ID. The content receiving unit transmits an own personal ID when a request for supplementary information to identify a target person from a content transmitting unit of a photographer, receives digital photo contents composed using an image captured from the content transmitting unit and the personal ID, and displays the received digital photo contents. | 12-04-2008 |
