The recording of lecture videos and disseminating them is becoming popular. However, recording and postprocessing daily lectures still demands much human effort and financial resources. Our goal is to develop a cost-effective and labor-saving video processing system that can record lectures in high-definition and process them for additional analysis and publishing. Our main idea is that high-definition recording itself is labor-saving. A stationary high-definition camcorder can record a lecturer and an entire classroom clearly so that notes can be read on a whiteboard and projector screen. Therefore, no camera operator is necessary during recording. We succeeded in implementing a cost-effective system without expensive hardware components for capturing a high-definition video signal. In this contribution, we describe the design and operational results of our system, which has recorded about 20 lectures every school week since 2010.
