Patent Images
1. A device, comprising:
- a camera with a field of view;
a proximity detector arranged to detect an object in the field of view, the proximity detector being separate from the camera, and a sensing area of the proximity detector overlapping with the field of view of the camera and at least a portion of the field of view of the camera is non-overlapping with the sensing area; and
a controller to;
receive images from the camera;
receive a proximity indicator from the sensing area of the proximity detector overlapping with the field of view of the camera, wherein the proximity indicator originates from the proximity detector and indicates absence or presence of the object within the sensing area that overlaps with the field of view of the camera, wherein the proximity detector has a threshold distance and provides the proximity indicator in response to detecting the object within the threshold distance; and
process the images from the camera to provide an occupancy indication based on the proximity indicator, wherein a first occupancy detection technique is used in the absence of the object from the sensing area, and a second occupancy detection technique is used when the object is present in the sensing area, wherein the first technique is different from the second technique and uses lower power than the second technique.

Abstract
System and techniques for an occupancy sensor are described herein. Images from a camera can be received. Here, the camera has a certain a field of view. A proximity indicator from a proximity detector can be received when an object enters the field of view. The images from the camera are processed to provide an occupancy indication. A first technique is used for the occupancy indication in the absence of the proximity indicator and a second technique is used otherwise.
