Abstract: According to one embodiment, an image detection system includes an imaging apparatus, an edge extraction unit, a specific-edge extraction unit, a candidate area extraction unit, and a to-be-detected area determination unit. The edge extraction unit extracts edges each representing a boundary line between areas with different features. The specific-edge extraction unit extracts specific edges including at least remaining edges present in background image and input image. The candidate area extraction unit extracts candidate areas for a preset area to be detected. The to-be-detected area determination unit determines the area to be detected from candidate areas extracted.

Abstract: According to one embodiment, an elevator system includes a camera, a passenger detection module and a controller. The camera is capable of imaging a particular range in a direction from a vicinity of a door of a car to a hall when the car arrives at the hall. The passenger detection module detects presence or absence of a passenger who intends to get into the car by focusing on movement of a movable body within a specific area by using a plurality of time-series continuous images which are captured by the camera. The controller controls an opening/closing operation of the door based on a detection result of the passenger detection module. A width of the area is being set greater than at least a width of the door.

Abstract: According to one embodiment, a user detection system includes a camera, a boundary detector, a user detector and a controller. The camera is installed in a peripheral region of a door, and captures a running region when opening or closing the door and a region near the door. The boundary detector detects a boundary between a first structure and a second structure in the region near the door based on an image captured by the camera. The user detector detects whether there is a user in the running region based on a result detected by the boundary detector. The controller controls an open/close operation of the door based on a result detected by the user detector.

Abstract: According to one embodiment, an elevator passenger detection system comprises an image capturing unit, a detection area setting unit, and a detection processing unit. The image capturing unit captures an image in a predetermined range including a vicinity of a doorway at which a door is opened or closed, from an inside of a car. The detection area setting unit sets a detection area on a front return panel provided on at least one of sides of a doorway of the car, on the captured image obtained by the image capturing unit. The detection processing unit detects presence of a passenger or an object, based on the image in the detection area set by the detection area setting unit.
