Image monitoring device for elevator with image recording
First Claim
1. An image monitoring apparatus for an elevator, comprising:
- image recording means for recording a sequence of images of an interior of a car photographed by a camera, with a delay between the recording of successive images in the sequence of images of the interior of the car;
means for determining a moving amount of a passenger in the car based on a comparison between a newly photographed image in the sequence of images of the interior of the car and a previously photographed image in the sequence of images of the interior of the car;
means for detecting a violent behavior of the passenger in the car when the determined moving amount exceeds a reference value; and
means for displaying, arranged in the interior of the car, the sequence of images of the interior of the car when the violent behavior of the passenger in the car is detected, whereinthe image recording means reduces the delay between the recording of the successive images in the sequence of images of the interior of the car when the violent behavior of the passenger in the car is detected.

Abstract
An image monitoring apparatus for an elevator includes an image recording section configured to record a sequence of images of an interior of a car photographed by a camera, with a delay between the recording of successive images in the sequence. The apparatus also includes a detecting section configured to detect, based on an image in the sequence of images of the interior of the car, a violent behavior of a passenger in the car, and a display unit arranged in the interior of the car and configured to display the sequence of images of the interior of the car when the violent behavior of the passenger in the car is detected. The image recording section is further configured to reduce the delay between the recording of the successive images in the sequence of images when the violent behavior of the passenger in the car is detected.
