| Research Abstract |
For the sustainable development of the educational material of the daily-life kinetical phenomena in the introductory course of physics, a high-speed video system with a rate of 400 frames per second (fps) was arranged. The system is composed of a low-resolution (504 x 121 pixels on the specification sheet) white-and-black (8 bit per pixel) CCD camera connected to a PCI board which is installed in a desktop PC, and free and commercial softwares for the image processing and the video rendering. The remarkable merits are
1. needless of the special light source (usual brightness under the sunlight is enough),
2. an about 6-second continuous shooting (almost moving bodies in the classroom is within one second),
3. needless of the hardware trigger (the triggering time will be found in one of the images),
4. an efficient cyclic development (about 30 minutes for obtaining body position, rotating and convoluting images, trimming, and the video rendering) with a small data volume (about 300 M bytes for one shoot).
For comparison with the conventional stroboscope equipment, the present system has a large advantage for the accessibility impression of the students, which is often missed in the conventional analysis-oriented experiments. In the learning material spotlighting the daily-life phenomena, the sustainable development is quite important because teachers who find a novel interesting phenomenon must study its contributing factors and re-create the phenomena without irrelevant factors. Some images and videos are opened to the public through a web site (mainly in Japanese) http: //www. e. chiba-u.jp/〜tkato/BorderlessPhysicsEducation/.
