Controlled nuclear fusion is the most promising clean energy resource of next generation. In magnetic confinement fusion Toka-maks,plasma-wall interactions cause damage to materials during long-time plasma discharge easily,which makes a great influence on safety and operation life of the instrument. The infrared endoscope in EAST that has a wide field of view can monitor the temperatures of upper and lower divertors,LHW antenna and movable limiter. In this paper,the image collecting and processing of the infrared CCD diag-nostic system in EAST during plasma discharge,and overall structure of the system,hardware and software design are introduced in de-tail,including image storage,playback,format conversion and remote transmission based on TCP protocol. Besides,the data acquisition and service system has been run successfully and stably in EAST,which provides relevant information for active control of heating power and plasma shape control,and further provides the safeguard for safe operation of the equipment,and it well satisfies all requirements of the experimental diagnosis.
