Abstract :
This paper analyzes the limitations of zoom function which can not be achieved in current 3G video phone. A 3G video phone solution for free-level zoom is proposed. The solution proposed in this work mainly consists of software components, according to which hardware needs to be selected. It also gives the video phone terminal structure, block diagram for H.324M video phone terminal, the main software functional blocks and the overall work flow chart of the designed solution. The free-level zoom function of video phone is realized by adding zoom settings software module and zoom control software modules, as well as by the use of a menu or shortcut keys.
