<p>This motion sensor device is provided with an imaging sensor (501), a first and second light source (502, 503), and a control circuit (531) that is configured in a manner so as to control the imaging sensor (501) and the first and second light sources (502, 503). The control circuit (531) is configured in a manner so as to repeat an operation for imaging a first frame by means of the imaging sensor (501) while causing the first light source (502) to emit light at a first time, an operation for imaging a second frame by means of the imaging sensor (501) while causing the second light source (503) to emit light at a second time, and an operation for generating distance information to the subject on the basis of the first image acquired by imaging the first frame and the second image acquired by imaging the second frame, and the amount of light emission of the first light source (502) and the amount of light emission of the second light source (503) are controlled separately on the basis of information obtained from previous imaging.</p> |
