FPGA による画像処理演算器の設計

Abstract

An image processing system with a FPGA has been developed. the system has the following functions.1) BMP images taken with a digital camera and stored in a PC are transferred to a SDRAM on a board including a FPGA through a PCI bus.2) Two images are read from the SDRAM and are processed by background subtraction method in the FPGA, and the resulted image is stored into the SDRAM.3) The result image are transferred to the PC via a PCI bus, and displayed. Processing time of background subtraction with the FPGA and with a software in a PC has been compared, and found that the former is several times faster then the latter.
