A Method of Digital Camera Work Focused on Players and a Ball

We aim at the realization of automatic adaptive contents production system of commentary soccer video based on digital shooting technique which is composed of digital camera work and digital switching technique for small audience such as a fellow some enthusiast and a individual. The digital camera work is defined as virtual panning and virtual zooming. Also, the digital switching is defined as the change of some virtual camera by controlling rapid change of frame location or size on a HD(high definition) material video. In this paper, we describe a method of digital camera work technique focused on players and a ball as a sub-system of automatic contents production system for commentary soccer video. The produced video contents with digital camera work is subjectively evaluated by AHP (Analytic Hierarchy Process).
