The shooting method in a surveillance video camera systems and surveillance video camera system

摘要

PPROBLEM TO BE SOLVED: To obtain high quality pictures in photographing an object image with a video monitor camera. PSOLUTION: A photographing condition (panning angle, tilting angle, and zoom magnification) at a predetermined photographing position (monitoring point) is set for a video monitor camera, and while the center coordinates of an electronic zoom segment position 49a on an imaging device 49 relative to the photographing position are calculated using a panning angle and a tilting angle, an electronic zoom magnifications in terms of the present optical zoom magnification is calculated from a zoom magnification, and a camera unit 40 is switched to a targeted photographing position, and electronic zoom processing is conducted from the electronic zoom segment position 49a. Then panning/tilting and optical zooming are driven in a direction offsetting electronic zoom processing, and an optical zoom processed picture is outputted. PCOPYRIGHT: (C)2004,JPO
