Recently, the trends of medical information technologies are capturing digital image from medical analog information, medical image aquisition, transmission, storage and query as well as integration with hospital information system. Analog medical visual information from ultrasonic, MRI can be changed into digital medical information, and to connect with medical video information system which need frame editing, 3D modeling and rendering. The purpose of this study is to design multi graphic image authoring tool and development of digital video editing functionalities, which can be used usefully for medical visual editing tool as well as vector image production system. The implementation methodology is based on Object-Oriented Modeling with primitive, media and composition object with reusability and inheritance characteristics, which can be useful for interleaving various type of media into video stream. The system assesment is based on international recommendation ISO 15504 81W process capability determination. We select 6 processes from Engineering process of system requirement analysis and design category, and determine capability for selected SIW process for system assesment.
