1. A method of image processing, comprising the steps of:
- constructing a results key at a first processing station;
providing the results key to an image capture andprocessing device remote from the first processing station,where the image capture and processing device includes a digital camera with a lens and is operable to capture an image presented to a field of view of the image capture and processing device;
using the image capture and processing device remotely on a standalone basis without communication with the first processing station to analyze the field of view image from the digital camera in cooperation with the results key, andto provide an output signal based on the results of the analysis; and
wherein the analysis includes detecting specific human movement associated with a likelihood of possible injury or harm as indicated by an imminent risk of a person getting out of bed and provides an output signal to raise an alarm when said specific movement occurs,wherein the lens has a total field of view and the step of using the image processing and capture device includes performing the analysis using a selected portion less than the total field of view.

Abstract
An image processing sensor system functions as a standalone unit to capture images and process the resulting signals to detect objects or events of interest. The processing significantly improves selectivity and specificity of detection objects and events in a series of motions that may precede a patient who is at elevated risk of falling.

18. In an image capture and processing device that contains a digital camera with a lens that is used to detect human movements, the device comprising:
-
an image processor for analyzing the human movements on a standalone basis to ascertain specific movements related to at least one action selected from the group consisting of characteristic movement patterns consistent with a human getting out of bed; and an output port for providing an output signal when the specific movements occur in the field of view, wherein the image capture and processing device includes a camera with a lens, the lens having a total field of view; and further includes program instructions that when executed on the image processor causes the processor to perform the analysis using a selected portion less than the total field of view. - View Dependent Claims (19, 20, 22)
