FPGA によるITU-656 ビデオカメラのインターフェイスおよび画像演算器の設計

Abstract

High-speed processing is necessary to perform image processing in real time. Hardware processing with FPGA is one of the ways to process images fast. A system processing images from video camera in real time has been designed. The system has the following blocks. 1) An interface circuit getting images from camera, de-inter-race and transfer them to SDRAM. 2) An image Processor. Two images read from the SDRAM are processed by subtraction and segmentation to 2 values. Then the resulted image is stored into the SDRAM. The processing speed with the FPGA was enough to perform real-time processing.
