Monitor subject monitoring device and method, and monitor subject monitoring system

A subject monitoring method comprising:

• an image data accepting step of accepting image data of a subject to be monitored;
• a physiological data accepting step of accepting physiological data of the subject;
• a first body state determination step of, based on the image data of the subject accepted in the image data accepting step, determining a first body state of the subject as being one of a normal state and an abnormal state;
• a second body state determination step of, based on the physiological data of the subject accepted in the physiological data accepting step, determining a second body state of the subject as being one of the normal state and the abnormal state;
• and
• a notification control step of,
• in a case in which each of the first and second body states of the subject determined by the first and second body state determination steps, respectively, is the abnormal state, issuing a notification indicating that the subject is in the abnormal state, and
• in a case in which one of the first and second body states of the subject, determined by the first and second body state determination steps, respectively, is not the abnormal state, causing whichever of the first and second body state determination steps that made the not abnormal state determination to re-perform the determination, and then determining whether or not the subject's abnormal state-indicating notification should be issued, based on a result of the re-performed determination.

A subject monitoring apparatus comprising:

• an image data input unit for inputting image data of a subject to be monitored;
• a first body state determination unit, based on the image data of the subject input from the image data input unit, to determine a first body state of the subject;
• a physiological data input unit for inputting physiological data of the subject;
• a second body state determination unit, based on the physiological data of the subject input from the physiological data input unit, to determine a second body state of the subject;
• and
• a notification control unit, configured to:
• issue a notification indicating that the subject is in an abnormal state, when each of the first and second body states of the subject determined by respective ones of the first and second body state determination units is the abnormal state, and
• in response to ascertaining a situation where the body state of the subject determined by one of the first and second body state determination units is a given first abnormal state, and the body state of the subject determined by a remaining one of the first and second body state determination units is not a second abnormal state corresponding to the first abnormal state, cause the remaining one of the first and second body state determination units to re-perform the determination for a given period of time or a given number of times, and issue the subject's abnormal state-indicating notification when the corresponding body state of the subject is determined to be the second abnormal state within the given period of time or the given number of times.

A subject monitoring apparatus comprising:

• a plurality of monitoring units adapted to provide respective data resulting from monitoring of the subject;
• a plurality of body state determination units operable, in response to said data of the subject from said plurality of monitoring units, respectively, to determine a body state of the subject as being either a normal state or an abnormal state;
• and
• a notification control unit operable to:
• (i) issue a notification indicating that the subject is in an abnormal state, when each of the body states determined by said plurality of body state determination units is the abnormal state, and
• (ii) if the body state determined by at least one of the plurality of body state determination units is not the abnormal state, cause the at least one of the plurality of body state determination units to re-perform the determination, and then issue a notification that the subject is in the abnormal state, based on a result of the re-performed determination, if each of the body states determined by said plurality of body state determination units is the abnormal state.
