摘要
The features of the Mobile Media API (MMAPI) technology, which lets developers build multimedia application including video recording and image capture into phones from different manufacturers, are discussed. J2ME grants access to a phone's camera through the operational library MMAPI, which is used to retrieve, open and play multimedia contents from any source. The MMAPI manages the camera just like any other multimedia source, in a straightforward manner. It creates a video stream by putting together snapshots taken form the camera and an image obtained is simply one of thes snapshots, rescaled and reformatted when necessary. Improved MMAPI implementation will let the terminals exploit the full potential of smart camera phones.
