  • Monitoring system and monitoring method
    Patent number: 7212650
    Abstract: A camera picks-up at least two images of a region where an object is present. A monitoring unit monitors the object and displays the images of the object on a display for a user. The monitoring unit obtains a difference image of the two images, and removes an image of a moving object that may be considered as a background image from the difference image to thereby obtain an image of the object. The monitoring unit determines the image of the moving object as the background image based on an area of the image of the moving object. The monitoring unit determines a state of the object based on barycentric positions of the images of the moving objects in the difference image.
