This study proposes that general users will produce UHD image contents or game background image. UHD realistic image gives reality with a 4K ultra high‐definition large screen. However, UHD contents are relatively lacked. In order to produce UHD contents, 4K images are needed. As shooting equipment is expensive, HD image is converted through upscale or pull down. Accordingly, in this study, we propose to take 4K definition static image with general camera to produce UHD contents, and to insert sound and effects and to sync using editing program. For experiment, we used 15 seconds' length image in 3840x2160 and 4096x2304 resolution respectively. In the experiment, it was found that image quality and volume increased and sense of reality changed according to definition and high frame rate. As another experiment, we used 15 seconds' length HD image in 3840x2160 resolution using high frame rate method. In the experiment, it was found that image quality, volume and sense of reality were changed according to high frame rate.

This research is to develop an expert system utilizing virtual reality and 3D image technologies for minimizing damages from natural disaster, especially storm and flood, which could be used as a training kid for people including the old. It also develops an expert system for storm and flood on very limited region, 3D animation application technology using optical motion capture techniques for heavy storm and flood, and 3D-based rendering technology using virtual reality techniques. This data based expert system should work exactly like real experts by adapting all expert knowledge and experience, so that users, especially the old and vulnerable residents not familiar with computer systems, could easily use the system by several button selections. The animated character based program will also be developed for the old and vulnerable residents to learn and understand what to do quite easily.
