Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a method to create a lecture video content easily from chalk and talk lecture video captured by a fixed HD camera for learning and teacher reflection. The proposing method is composed of the following process, (1) key areas of lecturer and characters are extracted from only each frame image, (2) vide scene is defined as the start of writing on the blackboard and the wipe of the blackboard, which is detected automatically from time change of character area and (3) learning-friendly lecture video is created.
The experimental results show that the proposed method can detect video scenes with high accuracy and create a video content, which is easy to watch even in low-resolution, using a representative image of the scene.
