Abstract
A subject-state detecting apparatus has an active distance measuring sensor including projectors for targeting measurement regions independently, and a photodetector for detecting reflection light reflected from a subject that receives light projected by the light projectors. A measurement parameter decision section decides in advance a body parameter to be measured. In response to the parameter, a distance measuring sensor setting section sets a measurement region of the active distance measuring sensor and an additional distance measuring sensor. A state decision section decides state of the subject from the outputs of these sensors.
Claims11
A subject-state detecting apparatus comprising:
- a distance measuring section that has an active distance measuring sensor including a plurality of light projectors controlled independently in targeting respective measurement regions, and a photodetector for detecting reflection light reflected from a subject that receives light projected by said plurality of light projectors;
- a measurement parameter decision section for selecting, body parameters measured by said distance measuring section based on states of the subject and surroundings of the subject;
- a distance measuring sensor setting section for setting a measurement regions of said active distance measuring sensor, in response to the body parameters selected;
- and
- a state decision section for analyzing a detection output of said active distance measuring sensor from the measurement regions, and for determining a state of the subject with reference to prescribed judgment criteria.
