Abstract: A mobile imaging unit includes a 360-degree camera disposed on a golf cart, a motorized-zoom-lens-equipped camera on a motorized camera platform, a microphone, a GPS receiver, and a direction detector of a lens. The mobile imaging unit determines an imaging target area of the motorized-zoom-lens-equipped camera by using a current position and golf course map information, drives the motorized camera platform, and stores video data captured in a magnified state, with the video data being accompanied by time information and area identification information. A digest creating device selects, as video data to be subjected to image analysis and extraction of a highlight scene, either video data from the 360-degree camera or video data from the motorized-zoom-lens-equipped camera in accordance with the area identification information accompanying the stored video data.
