Subject state detecting apparatus for detecting dynamically moving subject

摘要

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.
