We are developing an Automatic Camera control system for Education: ACE, which captures a lecture using both a blackboard and a screen. ACE focuses on an oblect ex plained by a teacher. When this recording strategy is real ized, it is necessary for ACE to extract a teacher's behavior and his/her explaining object. In this paper, we describe our algorithm to estimate a teacher's behavior by image processing and the camera control strategy to take suitable shots. We have applied ACE to recording a real lecture to validate it.
