摘要：
An apparatus includes a digital camera configured to capture a plurality of images of a region of a body of a subject, a photoplethysmography (PPG) sensor configured to sense blood flow information from the subject, and a processor in communication with the digital camera and the PPG sensor. The processor is configured to analyze a blood flow information signal from the PPG sensor and determine a heart rate frequency and/or a breathing rate frequency of the subject. The processor is also configured to analyze the plurality of images and determine whether or not a portion of the region of the body is modulating at a frequency that is similar to the heart rate frequency and/or the breathing rate frequency of the subject.
