1. 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.
