Document Type and Number:
Japanese Patent JPWO2022138063
Kind Code:
A1
Abstract:
A biological measurement device includes a light emitting device, a sensor, and a processing circuit. The light emitting device irradiates a first region and a second region, which is located on an upper side relative to the first region, of a forehead of a subject with light. The sensor detects first scattering light generated by the light incident on the first region and second scattering light generated by the light incident on the second region and outputs detection signals according to intensities of the first and second scattering light. The processing circuit selects one of the first and second regions as a target region based on the detection signals and/or an image signal indicative of an image including a face of the subject and generates and outputs brain activity data indicative of a state of brain activity of the subject based on the detection signal in the selected target region.
