Biometric measurement device and biometric measurement system

A biometric measurement device comprising:

• an optical detection device;
• and
• a processing circuit, wherein
• the optical detection device includes a first filter configured to transmit red light, a second filter configured to transmit one of green light and blue light, a first optical detection element that detects light from a living body through the first filter, and a second optical detection element that detects light from the living body through the second filter,
• the processing circuit generates biological information of the living body on a basis of first light detected by the first optical detection element and second light detected by the second optical detection element, and
• the first filter is an interference filter including a dielectric multi-layer and suppresses transmission of at least a part of light in a wavelength range greater than or equal to 550 nm and less than or equal to 600 nm.

A biometric measurement system comprising:

• a light source that is installed on a mobile object and emits blue light for irradiating an occupant of the mobile object;
• an optical detection device that is installed on the mobile object and detects reflected light from the occupant generated by the blue light;
• and
• a processing circuit, wherein
• the optical detection device includes a first filter configured to transmit red light, a second filter configured to transmit the blue light, a first optical detection element that detects light from the occupant through the first filter, and a second optical detection element that detects the reflected light from the occupant through the second filter, and
• the processing circuit generates biological information of the occupant on a basis of light detected by the first optical detection element and light detected by the second optical detection element.
