Assignee: nan
Field: Audio-visual technology (Electrical engineering)
Classification: CPC A  H | IPC A  H

Claim 0:
1. A multi-purpose video monitoring camera comprising:
a microprocessor;
a CMOS video camera operably coupled to the microprocessor;
a thermographic video camera operably coupled to the microprocessor and aligned with the CMOS video camera so that the thermographic video camera and the CMOS video camera have overlapping fields of view;
a display unit operably coupled to the microprocessor;
the microprocessor comprises a breathing detection module for calculating a breathing rate of a baby, and a suffocation detection module which is activated after the breathing rate of the baby determined by the breathing detection module falls below a predetermined threshold;
the suffocation detection module is configured to:
(1) obtain input from the CMOS video camera and the thermographic video camera;
(2) detect a position of a lead of the baby in the field of view of the thermographic video camera and perform face recognition on the input obtained in (1) to determine if a forehead of the baby is present in the field of view of the CMOS video camera;
(3) if output from (2) indicates that the forehead of the baby is not present, control a warning module of the microprocessor to output a warning signal;
(4) if output from (2) indicates that the forehead of the baby is present, perform face recognition on the input obtained in (1) to determine if a nose and a mouth of the baby is present in the field of view of the CMOS video camera;
(5) if output from (4) indicates that the nose and/or the mouth of the baby is not present, control the warning module to output a warning signal.
