PROBLEM TO BE SOLVED: To provide a technology of tracing a particular object at all times, generating its video image and providing a video image resulting from viewing the object from an easy to see position by automatically and optionally controlling a viewpoint position and a sight line direction. SOLUTION: Video information items from a multiple-lens imaging section 1 comprising many cameras located at different viewpoint positions and different sight line directions are composed into a video image in an optional viewpoint position and an optional sight line direction. An object position and direction detection section 2 detects the position and the direction of the object and a virtual camera position and direction calculation section 3 calculates the viewpoint position and the sight line direction of a virtual camera with respect to the object. Further, a video generating section 4 uses multiple-lens video data from the multiple-lens imaging section 1 to generate an image according to the information about the viewpoint position and the sight line direction of the virtual camera transmitted from the virtual camera position and direction calculation section 3.
