Abstract:
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.

Claim (Index 2):
The apparatus of  claim 1 , wherein the camera is arranged to capture sequential images including at least part of the underside of the item of furniture, wherein the edge corresponding to an edge of the item of furniture comprises an edge of the at least part of the underside of the item of furniture, such that a first portion of each image adjacent a first side of the edge shows the underside of the item of furniture and a second portion of each image adjacent a second, opposite side of the edge does not show the underside of the item of furniture.
