Abstract
This paper introduces a super high definition (SHD) image special effecting system focusing on system architecture and key hardware technologies. Recently, super high definition imaging has been investigated as a next generation communication media beyond HDTV. Requirement of industries, such as contents production and entertainment or electronic museums, to the SHD imaging system, is to realize processing images with special effect in reasonably quick response- time. Image processing like dissolve, fade in/out, wipe and filtering are indispensable for professional editing system as well as for entertainment or museum usage. These processing are useful techniques to generate seamless scene change. However, handling of SHD images is difficult, because only 2.8 nano second per pixel is allowable time for real time image processing. In this system, the following key technologies are employed: VLSI technologies based upon GaAs, parallel processing architecture, switching data path architecture with triplet frame buffer, and 2 input 1 output high speed ALU architecture. This system can be applied for several applications such as remote editing and printing, CSCW (computer supported cooperative work) for designing, remote education, electronic museum, and electronic catalogue.
