Biometric measurement device, biological measurement system, and biological measurement method

Abstract

To provide a biometric device, a biometric system, and a biometric method capable of acquiring position information on a body site to be measured in a direction perpendicular to the ground.SOLUTION: A biometric device includes: a detection part for detecting biomagnetism of a subject; an irradiation part for emitting a radioactive ray to the subject; an imaging part having a light reception surface for receiving a radioactive ray for imaging the subject on the basis of the radioactive ray from the irradiation part; a marker part imaged by the imaging part; and a processing part for outputting biological information on the basis of a result of the detection by the detection part and a result of the imaging by the imaging part. The processing part specifies the position of the marker part with respect to the detection part. The marker part and at least part of the subject are disposed side by side in a first direction intersecting with the normal line of the light reception surface between the irradiation part and the light reception surface.SELECTED DRAWING: Figure 1
