Abstract
A biological information acquisition device includes a near-infrared light source, a solid-state image sensor, and an information processing device, wherein the solid-state image sensor includes at least one specific pixel having a sensitivity peak in a specific wavelength band of 620 nm or more and 1100 nm or less, the information processing device is configured to repeatedly acquire (i) an emission image frame captured by the solid-state image sensor during an emission period of the near-infrared light source and (ii) a non-emission image frame captured by the solid-state image sensor during a non-emission period of the near-infrared light source, and the information processing device is configured to derive biological information on the basis of the emission image frame and the non-emission image frame.
