A novel automated camera control method for capturing desktop presentations introduced. For this purpose, typical features of shots and their camerawork that appear frequently in TV programs are discussed. To realise those features in this automated video capturing system, the purpose of camerawork is classified from two points of view: target and aspect-of-target. Then, the correspondence between the classification and typical shots and cameraworks is considered. The virtual-frame control algorithm based on this idea is proposed, and the implementation in the video production system. Experimental results are shown that verified this method through two kinds of experiments: virtual video capturing using CG animations and real video capturing of real presentations.
