Title:
IMAGE MONITORING SYSTEM AND CAMERA
Document Type and Number:
Japanese Patent JP2012065312
Kind Code:
A
Abstract:
To provide an image monitoring system with excellent portability which can be operated even at a place where a network cannot be constructed.
When imaging in daytime or at a bright place, a camera 10 takes an image of a subject with a near-infrared cut filter mounted thereon and outputs a color image. When imaging in nighttime or at a dark place, while the near-infrared cut filter is removed from the camera 10 and an LED lighting 11 irradiates the subject with near-infrared rays in synchronization with the shutter speed of the camera 10, the camera 10 takes an image of the near-infrared rays reflected by the subject and outputs a monochromatic image. The image output from the camera 10 is input to a recorder via a dedicated cable.
