Zusammenfassung: | PURPOSE: A photographing apparatus and memory sharing method between chips are provided to efficiently share a memory within a chip in case an image signal processor chip of a mobile terminal is not used. CONSTITUTION: A frame memory prepares in an image signal processor chip(520). The image signal processor chip receives a video signal from an image sensor(510). A control processor chip(530) receives image information through a first serial interface. The control processor chip accesses a second serial interface to a frame memory. The control processor chip is a multimedia processor chip or a baseband chip. |
