The apparatus comprises a light source to illuminate an edge-feature associated with a distal edge of the overhanging component, to create a shadow of the edge-feature on a region of the surface. The apparatus further comprises a camera arranged to capture sequential images of the region of the surface; and a processing unit. The processing unit is arranged to receive the images; detect an edge of the shadow in each of the received images, detect, in the received images, the appearance of a feature contiguous with the shadow edge; monitor how a detected feature changes over a time period; determine whether a change to the detected feature satisfies at least one predefined criterion for a subject exit event; and output a signal based on the determining.

The invention provides a central monitoring system based on a plurality of monitoring cameras and a central monitoring method. The central monitoring system conducts a central monitoring on the image from a plurality of monitoring cameras, which can reduce the monitoring burden on supervisors and reduce the occurring of missing abnormal events. Image processing is conducted based on respective image data of the plurality of monitoring cameras. Motion abnormity of a people can be calculated based on each camera, and display frame rate can be adjusted based on the abnormality. In this case, images from the monitoring cameras with large abnormity can be preferably seen; the monitoring burden on supervisors can be reduced; early discovery on abnormal events can be quickly realized and abnormal events can be quickly dealt with. The monitoring efficiency is improved through emphasizing and displaying the image of the monitoring camera adjacent to one monitoring camera where abnormality occurs or splicing among images.

This information processing method uses a computer to acquire first vehicle information, acquired from a vehicle monitored by a monitoring person, indicating the travel state and / or external state ofthe vehicle; determines the monitoring priority of the vehicle depending on the degree, based on first vehicle information, that monitoring of the vehicle by a monitoring person is necessary; on the basis of the monitoring priority, generates presentation information for monitoring of the vehicle; and causes a presentation device to output the presentation information.

An apparatus for detecting when a subject has exited an item of furniture is provided. The apparatus comprises a camera adapted to be arranged, when in use, below the underside of an item of furniture having an upper side for supporting a subject, the underside being opposite to the upper side, and a processing unit. The camera captures sequential images that do not include the upper side of the item of furniture, the images having a foreground corresponding to a region below the underside of the item of furniture and a background corresponding to a region adjacent the item. The processing unit receives images from the camera; detects, for each image, an edge corresponding to an edge of the item; detects the appearance of a feature contiguous with the edge; monitors how a detected feature changes over a time period; determines whether a change to the detected feature satisfies at least one predefined criterion for a subject exit event; and outputs a signal based on the determining.

An apparatus comprises a projector for fixed attachment to a moveable part of an item of furniture, which changes its position and / or orientation relative to a surface in response to a movement of a subject occupying the item of furniture. The projector is arranged to project a pattern onto the surface. At least one camera is arranged to capture sequential images of the surface. A processing unit is arranged to: receive the images from the at least one camera; detect the projected pattern in the received images; detect a change to at least one feature of the projected pattern in the received images; determine whether the detected change satisfies at least one predefined criterion for a subject exit event; and output a signal based on the determining.
