It is necessary to have them live in the complex electromagnetic circumstance. In order to make the equipment work efficiently and functionally, to forecast and to solve the EMC problems are important before realizing the whole system. Under the engineering practices of developing the 3\|dimension image processing equipment, the paper states how to set up the EMC models and deal with them in engineering. Further more, the physics characteristics of the electromagnetic interferes source and the electromagnetic interfere transmitting roads and the sensitive circuits which is easily wounded by interferes are analyzed in detail. Based on the analyzing, the forecasting of EMC is carried out. By the results, the EMC weak parts in the image processing equipment are easily founded in order that the EMC synthesizes can be realized. And using the step\|by\|step analyze\|synthesize methods the EMC problems can be solved well and the EMC aims are obtained. 信号处理 图像处理 电磁兼容 signal processing image processing EMC TP391.4 国家自然科学基金 （697750 2 2 ）;国家 863计划资助项目 （863 \|30 6 ZT0 4 0 6 3） 2003-01-01 2021-04-01 1
