The technology evolution of multimedia video processing has been widely applied in daily life with the applications of digital cameras, mobile TVs, digital CAM-Coders, portable multimedia players, DVD players, digital TVs, network videos, and surveillance videos. Moreover, the multimedia video processing has also been applied in the autotronics applications like automobile TVs, digital audio/video, GPS 3D navigation, rear view camera systems, as well as some new intelligent car technologies in developing like black-box for cars, and various video/image supplementary systems for car driving. According to this technology development trend, the famous leading companies in car manufacturing like BENZ, BMW, AUDI, VOLVO, TOYOTA, HONDA, NISSAN, FORD, and Continental AG, all deeply involved in developing the novel intelligent technologies for car driving. For pursuing the market share of this new technology, the domestic autotronics companies work closely with ITRI and ARTC to invest the research in this area. With this trend, it would be seen that there will be prosperous evolution in the various video/image supplementary technology for safety car driving in the near future. Using these technologies will further improve the safety in driving and reduce the car accident events as well. However, this technology development trend also induces great design challenges in this area in the aspects of high design complexity, much data storage requirement, high memory bandwidth, and high processing power. Following this technology trend and the goal of the 4C area research in NSC National Intelligent Electronics Project (NIEP), we propose a brand new project entitled “ISDRS: Intelligent Safety Driving Recording System and its key technology development” for bringing brand new applications for 4C area in the coming future according to the basis of our past research results in SOC. The design concept of the proposed ISDRS system is shown in Fig. 11-1. In this project, we would like to investigate the interesting research topics including high dynamic range night vision processing, panoramic video synthesis and H.264 video encoding with watermarking, car collision prevention technology, pedestrian/human detection technology, mobile traffic video transmission, and high performance circuit design technology as well as the 3-D integration and prototype for ISDRS system. Combining the above mentioned technologies could effectively induce various novel applications in the area of autotronics in the near future. Moreover, we will develop some advanced video/image processing technology in this project to enhance the research capability of Taiwan in this area. The plan of the main project and its associated sub-projects are shown in the following: In the three-year period of this project, we plan to deliver the following items: (1) ISDRS: Intelligent Safety Driving Recording System Prototype; (2) High-performance tone mapping algorithm and hardware accelerators for night scenes; (3) Panoramic video synthesis algorithm and hardware accelerators; (4) H.264 video encoder IP supporting panoramic video synthesis and watermarking; (5) Round view car collision prevention algorithm and hardware accelerators; (6) Pedestrian/human detection algorithm and hardware accelerators; (7) Mobile traffic video transmission algorithm; (8) Low power high performance circuit design technology and the ISDRS 3-D integration
