Abstract
A subject-state detecting apparatus has an active distance measuring sensor including a plurality of projectors for targeting measurement regions independently, and a photodetector for detecting reflection light from a subject that receives light thrown from the plurality of projectors. A measurement parameter decision section decides in advance a body parameter to be measured at present. 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 a state of the subject from the detection outputs of these sensors.
Claims10
A subject-state detecting apparatus comprising:
- a distance measuring section that has at least an active distance measuring sensor including a plurality of projectors for targeting measurement regions independently, and a photodetector for detecting reflection light from a subject that receives light thrown from said plurality of projectors;
- a measurement parameter decision section for deciding in advance a body parameter said distance measuring section is trying to measure;
- a distance measuring sensor setting section for setting a measurement region of said active distance measuring sensor and an additional distance measuring sensor in response to the body parameter decided to be measured;
- and
- a state decision section for analyzing at least one the measurement region of said active distance measuring sensor and a detection output of said additional distance measuring sensor, and for deciding a state of the subject with reference to prescribed criteria of judgement.
