Outline of Final Research Achievements

A distance learning system (the resolution of animation, 320x240 pixels) worked on Windows7 was developed and it was tried to use by school teachers. The teachers judged the animation on this system had too low resolution to use it in a classroom. We tried to improve resolution and to develop hardware for video synthesis. We thought, the difficulty of using the video synthesis system was caused by that a display indicated only a single video signal. We proposed the new digital video signal format without concept of full screen size or frame rate. Using this video signal, we designed autonomous video cameras which decided an indication point and a reduced scale rate by discussing each other, and a display which indicated them. We obtained the patent of Image Display Apparatus (pat. No. 5548898).
