Real-time Image Display System and HPI Communication Interface

摘要

In this paper.we introduce a cost-effective FPGAs (Cyclone EP1C12) as the core device of the embedded real-time image acquisition and display system.The system image acquisition device is the COMS image sensor OV7141,which provides the resolution of 640* 480 video signal to the FPGA. In the FPCA internal, by extracting brightness component, ping-pong conversion, 1/2 sampling , and finally transport the real-time video signal into TFT LCD and display. The paper also introduces the HPI module which communication with other equipments. This paper gives the system's hardware design diagram and software design module, and gives the simulation result of each module also.
