ABSTRACT:
A portable terminal wirelessly transmits a taken still image to a predetermined base station. An image processor receives the still image and extracts a digital watermark from the image. Further, the image processor transmits additional information according to the digital watermark to the portable terminal. Accordingly, various services using a digital watermark technique can be provided by using a portable terminal which can process a high-definition image to which a digital watermark can be embedded.
